Rotary cash drawer mechanism for currency dispenser
US 3880320 A
Abstract
An automatic banking unit at a remote customer station having a mechanism to dispense currency in response to the presentation of coded card means for verification and authorization followed by keyboard entries of data necessary to actuate the currency dispensing mechanism from which a selected number of paper money bills is delivered to a rotary cash drawer pocket normally located in a drawer "home" currency-receiving position. The drawer then rotates to an "open" position which permits the customer to remove the currency from the pocket. Upon removal, the drawer returns to a "dump" position for dumping any object remaining in the pocket. Then the drawer returns to "home" position, ready for another dispensing cycle of movement. The rotary drawer is equipped with sensor means which detect the presence or absence of currency in the drawer pocket so as to signal the fact that currency has been completely removed by a customer when removing currency from the drawer in open position. The drawer is equipped with locking mechanism to hold the drawer locked in "home" position, except during a dispensing cycle of movement; and also is equipped with means to prevent reverse movement of the drawer toward open position during its movement toward "dump" position.

PATENTEUAPRZQIHYS SHEET 5 BF 7 N19. 8 ow ROTARY CASH DRAWER MECHANISM FOR CURRENCY DISPENSER BACKGROUND OF THE INVENTION 1. Field of the Invention The invention relates to a currency dispenser actuated by a coded card after card verification. and more particularly to a rotary cash drawer construction having a pocket which receives a requested amount of currency from a stored currency supply in the dispenser mechanism of a remote banking unit and delivers the requested currency in the drawer pocket to a location readily accessible for removal by the requesting customer. Also. the invention relates to a currency dispenser cash drawer construction providing maximum security against attack. having a large delivery pocket providing maximum accessibility when open yet protecting the contents of the open pocket against air currents. and which construction may be easily serviced and has minimum possibility of injury to the customer user.

2. Description of the Prior Art Prior currency dispensers have a variety of means for delivering the currency being dispensed to the customer-user. Some currency dispensers have sliding or linearly-movable drawers containing currency dispensed, which drawers are moved to one or more open positions. In one known movable drawer type, the drawer is delivered to a partially-open position and then is pulled by the customer to a fully-open position to permit the currency therein to be removed by the customer. Another movable drawer type dispenser has a hinged drawer head which must be moved to a hinged-open position by the customer to remove from the drawer the currency being dispensed.

Other prior currency dispensers have delivered or ejected the currency being dispensed through a narrow slot. This places limitations upon the amount of currency or the thickness of a packet or sheaf of bills being dispensed.

Many difficulties and undesirable characteristics are present in the construction. operation or use of such prior dispenser cash drawer or delivery devices, including the requirement that the customer must manipulate a drawer or part thereof in use. Also, complications are involved in providing security against attack or unauthorized access in order to meet banking or underwriter requirements. The projection of a drawer from the facia of a banking unit when the drawer is in open position may result in the projecting drawer being bumped by or injuring a user. Complications may arise in providing a sliding drawer motion for opening and closing the drawer and at the same time in avoiding the possibility of customer injury by pinching a hand. The possible retention of undesired objects in the drawer presents a problem, as well as accessibility of the open drawer to air currents which may blow currency from the open drawer. The inability to abort a dispensing cycle in the event of a miscount of currency delivered to the drawer, or a change in the customers request characterizes prior devices. The limitation in the size of a packet of currency that may be delivered through a slot also can be a problem. Finally, prior devices involve complications in providing means to detect the presence or absence of an object in the drawer.

countered in the construction. operation or use of prior dispenser cash delivery devices.

SUMMARY OF THE lNVENTlON Objectives of the invention include providing a currency dispenser rotary cash drawer construction which eliminates the requirement of any drawer manipulation by the customer. which presents a large pocket opening or recess containing the currency being delivered for full. free and easy access by the customer for removal of the delivered currency, and which does not project outward of the facia of the dispenser unit but in which the recessed pocket provides protection against wind currents; providing such a rotary cash drawer construction which is rugged in structure. which has maximum security protection against attack, which at no time has an access passageway through the drawer rotor. and which is easy to construct. operate and service; providing such a rotary cash drawer construction which is movable between open". home and dump positions by drive mechanism including two drive motors. one of which provides a positive drive in one direction. and the other of which comprises a friction drive to avoid injury to a user who may have his hand in the rotary drawer pocket as the drawer moves away from open position. and which only can be engaged to drive in one direction at any one time and has simple driving movement controls; providing such a rotary cash drawer construction which presents a staging area for receiving from the currency supply the currency to be delivered. so that the delivered currency can be dumped by an abort operation in event of a miscount of currency delivered to the drawer pocket from the currency supply. or in event the customer wishes to change a request for currency to be dispensed. and in which the abort operation dumps currency from the pocket at the dump position; providing such a rotary cash drawer construction with simple detector means to determine the presence or absence of currency or other objects in the rotary drawer pocket. which detector means is free of parts movable relative to the drawer components; providing such currency dispenser rotary cash drawer construction having maximum currency-receiving and dispensing pocket volume in relation to a minimum amount of space required for the device; and providing a new rotary cash drawer construction for currency dispensers which achieves the stated objectives in a safe. effective, easily-serviced manner. and which solves problems. and satisfies needs existing in the field of coded card-operated currency dispensers.

These and other objects and advantages may be obtained by the new rotary cash drawer construction for currency dispensers. the general nature of which may be stated as including in a banking unit of the type in which currency is delivered in requested amounts from a supply in the banking unit to a dispenser drawer. and in which the drawer moves to an open" position for dispensing the currency to a customer-user; the combination of a banking unit housing having a recessed facia wall formed with a relatively wide, elongated slot having spaced upper and lower edges. through which housing slot access is gained to currency being dispensed;

DESCRIPTION OF THE PREFERRED EMBODIMENT In typical automatic banking unit for dispensing currency in response to the presentation by a bank customer of coded card means is indicated at 1. Such currency-dispensing unit I may be energized upon a customer presenting or entering a coded card into slot 2. Then the coded card is verified to confirm that it is an authorized card and that the user thereof is the authorized user.

After card and customer verification has been carried out, keyboard entries may be made by the customer at 3 in accordance with instruction presented to the customer at instruction panel 4. The entries among other matters indicate the amount of currency that the customer desires to withdraw. As a result of proper keyboard entries. the currency is discharged from a currency supply to conveyor means which delivers it to the pocket 38 of the rotary cash drawer generally indicated at 6. The supply of currency is held in a protected location within the housing of banking unit I.

This currency supply and delivery mechanism is generally indicated by the block 7 in FIG. I, and is equipped with conveyor means 8 which delivers the requested amount of currency to the rotary cash drawer 6. The currency supply and conveyor mechanism 7-8 which delivers currency to the cash drawer 6 forms no part of the invention but may comprise a standard unit such as shown in Whitehead Et Al US. Pat. No. 3,760,158.

The rotary cash drawer 6 has rotor support frame means including an upper frame member 9, a lower frame member 10, and end frame members 11 and 12. Frame members 9 and 10 preferably have flanges 13 and 14 which are bolted at 15 through flange bolt holes 16 and through a housing wall portion 17 to a frame member 18, L-shaped in cross section (FIG. 2). The housing wall 17, upper and lower frame members 9 and 10 and mounting frame member 18 each preferably is made of relatively heavy protective plate metal of the required thickness to provide the necessary security against unauthorized access by an intruder to the interior of the housing of remote unit 1. Thus. the rotary cash drawer assembly 6 is located within and has security protection by the secure housing of unit 1.

The banking unit housing 1 preferably has a recessed facia indicated at 19 in FIG. 1, and this facia may be trimmed with a trim member indicated generally at 20. The trim member 20, frame member 18 and housing wall 17 jointly are formed with a relatively wide elongated slot having spaced upper and lower edges 21 and 22, and access is gained to the rotary cash drawer 6 through the slot defined by edges 21 and 22 in a manner to be described.

The rotary cash drawer 6 has a rotor 23. Rotor 23 has a cylindrical outer wall 24 with a cylindrical outer surface 240 and is provided with stub shafts 25 and 26 journaled, respectively, in bearings 27 and 28 mounted in the end frame members 11 and 12. Rotor stub shafts 25 and 26 project outwardly. axially, respectively. from transverse rotor partition walls 29 and 30. A recessed annular cavity 31 and 32 is formed in the ends of rotor 23 beyond partition walls 29 and 30, respectively, and surrounding portions of stub shafts 25 and 26, as shown in FIGS. 5 and 6. Thus. rotor 23 is rotatable between the spaced upper and lower support frame members 9 and 10, as shown in FIGS. 13-15. Lower frame member 10 is cut away behind its flange 14, as indicated at 33 in FIG. 13 and in dotted lines in FIG. 3, to leave only fingers 34 projecting rearwardly from either end of the lower frame member 10.

A portion of the rotor 23 as shown in FIGS. 4, 9, 10 and 13-16 projects forwardly beyond the front surfaces 35 of the flanges 13 and 14 of upper and lower frame members 9 and 10. The projecting rotor portion also projects through the housing slot between the upper and lower slot edges 21 and 22 (FIGS. 1 and 2).

A longitudinally-extending arcuate slot 36 is formed in the cylindrical rotor wall 24, and a liner member 37 extending axially of rotor 23, generally U-shaped in transverse cross section, is mounted within the cavity formed by cylindrical rotor wall 24 with the spaced open liner U-edges 37a and 37b aligned with the spaced edges 36a and 36b which form the arcuate rotor slot 36 (FIGS. 13-15). The aligned rotor slot edges 36a and 36b and liner edges 37a and 37b define spaced rotary cash drawer lips which are adapted, when the rotor 23 is in the open" position shown in FIGS. 3, 4, 5 and 13 to be aligned with the spaced housing slot edges 21 and 22.

Rotor 23 is rotatably movable between the open" position shown in FIG. 13, the home" position shown in FIG. 15, and the *dump" position shown in FIG. 14.

The U-shaped liner 37 thus forms a pocket generally indicated at 38 which opens through the opening defined by the arcuate slot 36 and liner edges 37a and 37b. When the rotor 23 is in the open" position of FIG. 13. the U-walls of liner 37 preferably extend generally horizontally. as shown; and there is full. easy and free access through the larger opening to the pocket 38.

The opening of pocket 38 is directed inwardly. upwardly within the banking unit housing when the rotor 23 is in the home" position. shown in FIGS. 2 and 15. When the rotor 23 is in the dump" position of FIG. 14, the opening of pocket 38 is directed downwardly within the banking unit housing above a tray 39 movably mounted within the housing.

The liner 37 is supported within the rotor 23 by angle brackets 40 bolted at 41 and 42, respectively, to end portions of the liner 37 and rotor partition walls 29 and 30 (FIGS. 6-8).

Rotor 23 preferably is counterbalanced to compensate for the arcuate slot 36 by mounting weights 43 and 44, respectively. in the recessed end cavities 31 and 32 of the rotor (FIGS. 7 and 8). the weights 43-44 being held in place by screws 45. A boss 46 is formed integrally of rotor partition wall 30 (FIG. 8) projecting through the weight 44, and a rotor control stop pin 47 is mounted on boss 46 projecting from the right-hand end of rotor 23 (FIGS. 3. 7 and 8) for a purpose to be described.

A pair of sensor sight openings 48 formed in each rotor partition wall 29 and 30, and the openings 48 of each pair are located at diametrically opposite positions (FIGS. 6 and 7). These locations of the openings 48 of each pair are disposed vertically one above the other. as shown in FIGS. 6 and 7 when the rotor is in the "open" position. illustrated in FIG. 6.

A series of four prisms 49. 50, 51 and 52 is mounted on the exterior of the U-shaped leg walls of liner 37 (FIGS. 6, 13, 14, 15 and 18). The prisms thus are located in the moon-shaped cavities formed between the rotor wall 24 and the leg walls of U-shaped liner member 37.

Each prism preferably is a molded and polished plastic part with a mounting flange 53 (FIG. 18) and a prism cylinder 54 having a flat face 55, an angled face 56, and an end face 57 arranged at right angles with the flat face 55 at the underend of the cylinder 54 and formed as a part of the underside of flange 53. Openings 58 are formed in the liner walls to expose the prism end faces 57 to the interior of the liner pocket 38. The prisms are held in place by mounting bolts 59.

Electric eye bulbs 60a and 60b are mounted. respectively, on the end frame members 11 and 12 outside of openings 61 and 62 formed therein which are aligned with the upper openings 48 (FIG. 6) when the rotor is in open" position; and light sensor photocell switches 63 and 64 are also mounted, respectively, on frame members 11 and 12 opposite openings 65 and 66 in end members 11 and 12. The photocells and openings 63-66 are aligned as shown in FIG. 6 with the lower openings 48 in the rotor partition walls 29 and 30.

Thus. a light beam from the electric eye bulb 60a (FIG. 6) is directed through openings 61 and 48 and through the flat face 55 of prism 49, and part of the beam is reflected from angle face 56 and passes through the end face 57 of prism 49 and is directed downward to the end face 57 of prism 51 and is partially reflected by the prism angle face 56, and passes outward from prism flat face 55 toward the Iefi through aligned openings 48 and 6S striking photocell 63. The

path of such light beam is shown in FIG. 6 by the dotdash line 67.

A similar light beam is projected from electric eye bulb 6011 through prisms 50 and 52 and the beam strikes photocell 64. The purpose of these light beams and the electric eye-photocell systems is described below.

Rotor 23 is rotatable in either direction between limits of movement controlled by the stop member 68 (FIGS. 3 and 11) having an adjustable stop abutment 69 for the open" position and an adjustable stop abutment 70 for the dump" position. Stop member 68 is mounted on the inside face of the end frame member 12 (FIG. 3). Stop abutment 70 is engaged by rotor control stop pin 47 to limit clockwise rotor movement, viewing the right end of the mechanism (FIG. 4), as shown in FIG. 12 wherein the rotor is in dump" position with the slot 36 opening downward.

Stop abutment 69 is engaged by stop pin 47 to limit counterclockwise rotor movement when the rotor is in open" position, as indicated in FIGS. 3 and 10. At this time. the rotor access slot 36 is directed to the left in FIG. 10 or opens toward the viewer in FIG. 3.

When the rotor 23 is in home" position (FIG. 11), the access slot 36 opens upwardly toward the right viewing FIG. 11; and at this time, a lock pin 71 is projected through an opening 72 in the upper frame member 9 and into an aligned opening 73 in the rotor wall 24 communicating with the recessed cavity 32. The stop pin 71 is shown engaged in the home" position illustrated in FIG. 11 and is shown disengaged in other positions illustrated in FIGS. 3, 6, l and 12. Lock pin 71 is actuated by a solenoid 74. A rotor movement control printed circuit optical limit switch plate or panel 75 is mounted by bolts 76 and spacers 77 (FIGS. 6 and at the right-hand end of the mechanism (FIG. 6). Panel 75 on its outer face has an open sensor 78, a home sensor 79, and a dump" sensor 80; and these sensors are adapted to have light beams interrupted by movable fingers mounted on the rotor.

The movable finger means consist of an inner disc 81 with a projecting L-shaped finger 82 and an outer disc 83 with a projecting L-shaped finger 84. The discs 81 and 83 are relatively adjustable rotatably with respect to each other and may be clamped in adjusted position by screws 85. The assembly of discs 81 and 83 on a hub 86 is adjustably mounted on the projecting end 87 of stub shaft 26.

Finger 84 of outer disc 83 interrupts light in home" sensor 79 which acts as a limit switch to control operation of the drive motors for the rotor 23, to be described; while finger 82 selectively actuates open sensor 78 (FIG. 10) or dump sensors 80 (FIG. 12) as limit switches to control the drive motors for rotor movement. The printed circuit optical limit switch panel 75 and its components are of typical construction and panel 75 is connected by a cable 88 with the circuitry. to be described, for controlling the operation of the rotary cash drawer 6.

A motor mount plate 89 is pivotally mounted at 90 to end frame member 11. Plate 89 normally is biased in a counterclockwise direction by spring 91, viewing FIGS. 9 and 16. A drive motor 92 is mounted on a lower portion of plate 89 having a drive gear 93 adapted to be moved to a position engaging gear 94, mounted on the stub shaft 25 of rotor 23. The motordrive gear means 92-94 provides a positive drive means engageable with the rotor 23 to rotate the rotor in one direction, counterclockwise viewing FIG. 12, and clockwise viewing FIGS. 13, I4, 15 and 16 from dump" position to home position, and also drives rotor 23 from the home to the open" position of FIGS. 9. I0 and 13.

There is a second separate drive motor 95 mounted on an upper portion of plate 89 having a friction drive wheel 96 adapted to engage the periphery of the rotor 23 (FIG, 16) when the plate 89 is rotated clockwise (FIG. 16) by the action of a solenoid 97 connected by a linkage 98 with bracket means 99 mounted on the upper end of motor mount plate 89.

Plate 89 when rotated clockwise, as shown in FIG. 16, disengages the gear drive and engages the friction drive 96 with rotor 23. Thus, when friction drive motor 95 is energized, drive wheel 96 rotates rotor 23 counterclockwise viewing FIG. 16 from open" position back to dump position. This rotor movement is clockwise from the open' position of FIG. 10 to the dump position of FIG. 12.

Preferably, movement of plate 89 is guided and controlled by the bushing pins 100 extending through slots 101 in the lower end of plate 89.

A segment ratchet wheel 102 is mounted on the outer end of stub shaft 25. Ratchet pawl 103 may be moved in a position to engage the ratchet teeth of wheel 102 to prevent clockwise movement of the rotor 23 (FIG. 16) as the rotor is being rotated counterclockwise by the friction drive wheel 96 from the open" position to the dump position. Pawl 103 is activated to ratchet wheel engaging position by push rod 104 connected at 105 with plate 89. Thus, when plate 89 is moved clockwise (FIG. 16), by solenoid 97 to engage friction drive wheel 96 with rotor 23 and motor 95 is energized to to tate rotor 23 in a counterclockwise direction, push rod 104 moves pawl 103 to ratchet engageable position.

When the gear drive 92-94 is engaged and the friction drive 96 is disengaged (FIG. 9), push rod 104 moves pawl 103 to the position of FIG. 9 in which it does not engage ratchet wheel 102. It is necessary to prevent retrograde movement of rotor 23 when it is being moved from open" to dump" position by the friction drive, in order to prevent anyone from backing up the rotor for any purpose whatsoever during friction drive operation to and at dump position. Thus, an unauthorizd person cannot gain access to or remove material in the rotor pocket that is intended to be dumped.

On the other hand, the friction drive is necessary to prevent injury to the hand of an authorized user if trapped in the pocket during rotor movement away from open" position.

A transformer 106, relays 107, etc., may be mounted on a housing 108 located on top of the upper frame member 9. Circuitry, cable harnesses, terminal strips, etc., may be located on or within the housing 108 from which circuitry to the motors, solenoids, electric eyes, photocells and control panels may extend for operating the mechanism in accordance with a programmed cycle of movement.

The electric eye 60a and 60b and photocell 63 and 64 systems provide beams of light as described and as illustrated by the dot-dash line 67, when the rotor 23 is in open" position to determine the presence or ab sence of any object such as paper money in the pocket 38.

In other words, if paper money has been delivered to the pocket 38 in the "home" position and the rotor 23 moved to open position to render the money accessible to a customer, the paper money lying on the lower leg of liner 37 (viewing FIG. 6) will interrupt either the beam 67 or a similar beam emanating from electric eye 64. Interrupted light beams may provide a control of circuitry in one condition. When the customer removes the paper money, the beam 67 and the similar one at the right of FIG. 6 will no longer be interrupted. Thus, energized photocells 63 and 64 provide another condition which senses the absence of anything in the pocket. This may be used to inititate a next step in the programmed operation of the rotor.

CYCLE OF ROTOR OPERATlON IN GENERAL Assume that the rotatable cash drawer 6 is in a waiting condition with the rotor in home" position. as shown in FIGS. 1, 2, ll and 15. A customer desiring to obtain currency from the automatic banking unit l, presents his coded card in the usual manner to the slot 2 after which the customer is directed to key in various information so that the card may be checked and the amount entered as to currency which the customer desires the unit to dispense.

Keying in the amount activates the currency supply and delivery mechanism 7 to deliver the requested amount of money to the conveyor 8 which discharges the currency into the open pocket 38 of the rotor 23. The money count, meanwhile, is verified by the delivery mechanism 7. Upon verification, a signal activates the circuitry for the rotary cash drawer 6 to energize solenoid 74 to retract the lock pin 71 (which is the deadlock for the rotor in home" position) to retracted position of FIGS. 6, l and 12.

At the same time, positive gear drive motor 92 is energized to rotate rotor 23 from home position to open" position of FIGS. 6, l0 and 13. When in open position, the electric eye photocell sensor system becomes operative. The money in the pocket 38 is accessible for removal by the customer. When the money has been removed, the sensor light beam system is re-established, signaling the friction drive motor 95 to be energized and the solenoid 97 to move plate 89 to engage the friction drive and rotate the rotor 23 from "open" position back to "dump" position of FIGS. 12 and 14. Thus, anything which may have been left in the pocket 38, or placed therein by a customer or an unauthorized person, is dumped from the rotor into tray 39.

[n the event that the customer does not remove the currency to be dispensed from the pocket 38 while the rotor 23 is in open position during a predetermined period of time, at the end of such lapsed time period, the rotor moves automatically from open" to dump position in order to dump the currency that was not removed.

After arriving at dump position and dwelling there for the necessary time to permit completion of the dumping operation, the programming of the equipment disengages the friction motor drive and engages the direct gear drive of the rotor to move the rotor from dump position to home" position. This completes the cycle and renders the equipment ready for the next cash dispensing operation.

Situations may arise in which the improved construction provides extra security and safe, accurate and protective operation. Among other matters, these may be described by two examples.

First, if the count of money supplied from the currency supply and delivery mechanism 7 is incorrect, the mechansim 7 delivers a signal to interrupt the programmed operation and directly energize the friction drive from motor to rotate rotor 23 from the home position of FIG. 15 to the dump" position of FIG. l4, thereby dumping the incorrect amount of money that had been delivered to the pocket 38.

Second, if a customer changes his mind regarding the amount of money being requested before the money has been made accessible at the slot between edges 2] and 22. the customer may depress a stop button at keyboard 3 which interrupts further operation of the entire money dispensing procedure and signals the rotor control to move the rotor to dump position.

In either instance, after the rotor 23 has been moved to dump" position and anything remaining in its pocket 38 discharged to tray 39, the normal cycle of operation again takes over and moves the rotor back to home" position, ready for the next cash-dispensing operation.

In each example, the operation of the rotary cash drawer is aborted, and anything in the rotor pocket 38 is dumped. Such capability involves what we believe to be a completely new concept in the automatic currency-dispensing field.

The dumping concept of the new rotary cash drawer provides further advantages in that the larger and readily-accessible pocket 38 with a wide opening permits objects other than currency or paper money to be contained therein, such as sacks of banking media, for example, checks, currency and coin to be deposited. Because of this capability, the rotary cash drawer can be used as a depository in which banking media may be deposited in the pocket 38 when the rotor 23 is in open" position and then in its cycle of operation, the material deposited will be dumped at the "dump" position into the tray or other receptacle.

Special protective features of the improved mecha nism include the provision of the horizontal rib I09 in the liner base wall which tilts any paper currency off of a vertical position, when rotor 23 is in open position, and which otherwise might have laid flat on the liner wall; so that it falls over by gravity when the rotor 23 is in the open" position of FIG. [3 and comes to rest on the liner bottom wall of the open pocket 38.

Other safety features characterizing the mechanism of the invention involve the deadlock 71 for the rotor when in "home" position. The deadlocking pin 71 is inaccessible from the exterior of the housing of the remote unit 1 and thus performs the same function as the bolt work for safes or vault doors. Further, the noback" pawl and ratchet mechanism 103-]02 prevents the rotor from being backed away to an open" position when the gear drive is disengaged and the rotor is driven by its friction drive away from open" position.

Another safeguard characterizing the improved mechanism is the light beam sensor systems which effectively signal or sense the presence or absence of objects in the pocket when in open" position. This is accomplished in a very simple manner involving no moving parts requiring adjustment, servicing and upkeep other than electric eye bulbs or photocells.

A further safeguard to the programmed operation 01 the rotary cash drawer involves the sensor control plate 75, its printed circuit, its optical cells 78, 79 and 80, and the optical interrupting fingers 82 and 84. This mechanism senses and provides limit switch control for the operation of the rotor by sensing the arrival. of the rotor at each of the home," open and dump positions.

Inspection of FIGS. 2, 13, 14 and 15 indicate that at no time is a through opening presented by the rotary cash drawer mechanism from the exterior to the interior of the unit, and that there is always a heavy protective plate wall presented guarding the interior of the unit. This wall may be formed of metal of required thickness and composition to present the necessary security against attack in accordance with bank security and underwriter's specifications.

WlRlNG DIAGRAM FIG. 17 is a schematic diagram for the wiring for the programmed operation of the rotary cash drawer 6. The wiring is illustrated typically in some of the other views of the drawings by cables, harnesses. wires, etc. In FIG. 17, several terminal strips. T-1, T-2, T-3, 8-16 and PWR-9, are shown as well as relays 107-SSR1, l07-SSR2 and l07-SSR3. Each of the relays may have a number of pin connections to provide the circuitry programmed operation.

Components illustrated, described and identified above and indicated in FIG. 17, include a transformer indicated at 106', the solenoid for the rotor lock pin 71 indicated at 74; the photocell light beam switch sensors indicating the presence or absence of currency in the pocket identified at 63 and 64', the light bulbs 60a and 60b; the friction drive motor 95; the gear drive motor 92; the drive plate solenoid 97; and the printed circuit board 75 carrying the rotor home" sensor 79, the rotor open" sensor 78, and the rotor dump" sensor 80, which function as limit switches. Connection for such components are indicated diagrammatically at terminal strip 5-16, and the various power supply connections are shown at PWR-9.

The various components and terminals or terminal pins for the wiring, illustrated in FIG. 17, may be contained in or on the control housing 108. The circuitry thus represented in FIG. 17 connects and controls the components for operation of the mechanism in the manner described.
