J E ROMEHLE MELSON F568 FKMO TAPE CARTRIDGE AND READER The instant invention relates to apparatus for storing and reading information bearing elongated flexible members such as recording tape orfilm and more particularly to such apparatus including cartridge means for storing and feeding such FIG. 13 is a fragmentary view of the cartridge of FIG. 12 showing operation on the tape of the cartridge.

FIG. 14 is a side view of tape transport apparatus showing modifications to the apparatus of FIG. 12 and tape or film which may be readily and easily loaded into print- Numerous applications of tapes necessitate storage thereof for subsequent use. It is typical to enter data through a Flexowriter device which by the selective operation of its typewriter keyboard, simultaneously prepares a paper tape by punching or printing. The prepared paper tape is then ready for use as an input recording to a computer, data processor and the like. Such tapes must be carefully handled to prevent tearing or any damage which may affect feeding of the tape and damage or alteration to the data stored therein. Also data entered into the tape may fall into the categories of program subroutines, permanent lists and the like which will be reused frequently. This necessitates numerous removal and replacements of the tape upon the processing unit.

The instant invention contemplates'the use of a tape car- FIG.- is a side view of tape transport apparatus showing further modifications to the apparatus of FIG. 14.

It can be seen from the foregoing description that the instant invention provides a simple, easy-to-use cartridge for paper tape or other forms of tape which facilitates storage, transportation, use and protection of the tape by provision of a housing'which substantially completely surrounds the stored tape andprovides simple straightforward operative coupling with either tape readers, printers or computers and peripheral tridge which substantially fully encloses the tape and its reversible takeup and feed reels. An access opening is provided for engaging the tape by read (or punch) means when the cartridge is positioned relative to the reading station. Since positioning and/or removal of the cartridge does not require any physical handling whatsoever of the tape, it remains immune from physical strain or damage or other abuse while being removed, replaced, transported, stored or otherwise used.

It is therefore one object of this invention to provide a novel tape transport and apparatus for reading same for use in computers, data procemrs and the like.

Another object of the instant invention is to provide a novel tape cartridgeremovably mounted upon a tape reading station, for recording or readout purposes, which tape is immediately accessible to the read or write head assembly and yet is substantially fully enclosed by the cartridge housing to,

facilitate handling, storage and other use.

These and other objects of this invention will become apparent when reading the accompanying description and drawings in which:

FIG. 1 is a side view of a tape cartridge assembly designed in accordance with the principles of the instant invention and showing the interior components thereof with the front cover being substantially completely removed.

FIG. 2 is an end view of the assembly of FIG. 1 with certain of the parts removed for clarity showing the manner in which the cartridge is maintained in the operative position of the reading station. I

FIG. 3 is a detailed view of alternative reading means to that of FIG. 2.

FIGS. 4 and 5 are side in bottom views respectively, of a punching means for the tape housed in the cartridge.

FIG. 6 and 7 are perspective views showing alternative guide means for removably positioning the cartridge in the operative position.

FIG. 8 is a sectional view of FIG. 6 taken along 8-8 showing the means for coupling the driving means to the cartridge takeup and feed reels.

FIG. 11 shows another preferred embodiment in which the switches 36 are each comprised of sensing fingers 37 which are biased toward the tape and will close a circuit (contained within the switch housing) when momentarily entering a hole punched in the tape.

FIG. 12 is a side view of a tape cartridge with a sidewall removed and means for drawing the tape out of the cartridge.

input-output devices.

There is shown in FIG. 1 a design for a tape carrying magazine or cartridge 10 and electromechanical reading or sensing means for codes provided on the tape thereof as a plurality of holes in the tape disposed in the form of coded recordings, such as binary digital codes. The magazine 10 which is shown with one wall 13 I thereof substantially completely removed so as to reveal the internal contents of the magazine, includes a housing 11 of substantially rectangular parallelepiped shape having sidewalls 12 and 13, end walls l4, l5 and front 16 and rear wall 17. The sidewalls l2 and 13 are shaped and fabricated of sheet metal or are molded of plastic to define means for bearingly supporting the shafts 23 and 24 of a plurality of reels l9 and 20 of paper or plastic tape 2]. Reel 19 serves as a supply means for said tape and 20 as a takeup means therefor although the tape may be driven in either of two directions by the means described hereafter for activating the code sensing means.

The tape 21 unwinds from reel 19 around a first idler wheel 25 supported in rotation by either or both the sidewalls l2 and 13 of the cartridge and then passes between guides 27 and 28 which may be formed integral of the material of either of said cartridge walls or may comprise small idler wheels supported thereby.

An opening 18 is provided in the end wall 15 of the cartridge housing 11 through which the tape 21 passes permitting access to the tape of the reading device. The tape thereafter passes between guides 29 and 30 which are similar in function to guides 27 and 28, and thence around an idler wheel 25' before returning to the coil 22b of said tape disposed on the takeup reel 20.

The entire cartridge or magazine assembly 10 is supported on a base 39 (see FIG. 6) such as a housing containing computing circuits or output means adapted to receive signals derived by a bank of transducers supported thereby for reading the tape. The housing or base 39 also contains means for driving a plurality of shafts, one of which 44 is illustrated in FIG. 2, which shafts are operatively removably coupled to the shafts 23 and 24 of the reels for driving the tape from one reel to the other after mounting of the cartridge on the housing or base 39. The base 39 includes guide means for receiving and retaining the cartridge 10 in a predetermined .position with respect to a plurality of reading transducers also supported thereby. The guide means in FIG. 1 includes a pair of spacedapart angular supports 32 and 34 adapted to receive and predeterrninately position the cartridge housing 11 with respect to a bank of electromechanical switches 36 which are disposed thereby to position their actuator arms 37 across the tape whereby each actuator arm scans a particular channel or band area of the tape containing punchings or cutouts 21P as shown in FIG. 5. The channel recordings 21? run longitudinally along the tape and parallel to each other and a lateral row of cutouts or markings disposed across the tape may, for example, define a code representing a number, character or word. The actuator arms 37 of the electromechanical switches 36 are adapted to ride in and out of the openings 21F in the tape as the tape is driven therepast and to close and open a cir cuit as they are so actuated for generating electrical pulses to define binary or other forms of codes recorded on the tape.

Switches 36 are shown mounted at one end of the leg 33 of angular bracket 32 and are positioned thereby to permit their actuator arms 37 to engage the tape 21 and to ride in and out of the holes in each channel of the tape.

Other features of the invention illustrated in FIGS. 1 and 2 include means for locking the cartridge in position. A rotatable arm 41a is mounted at the end of a post 41b secured to base 39. The ann-4la is adapted to be rotated to frictionally engage the wall of the cartridge to retain same predeterminately in position. For removal of the cartridge, the arm 41a is rotated out of. the way to clear the cartridge wall. Also shown in FIGS. 1 and 2'is a pin 40 one or more of which are disposed in holes or receptacles 41 associated with base 39.

The pins 40 are urged by coil springs in the receptacles 41 to engage the sidewalls of the cartridge, yet may be retracted to permit the cartridge to beremoved from the stops by the illus'- photomultiplier tubes or photoelectric semiconductors 46 is mounted on a'bracket 33 secured to the reader housing base 39 with each cell thereof positioned to read a respective channel of the tape; A line light source 46L is removably mounted on the base 39 aligned with the cells 46 in a position such that it will pass through the opening 18a in the housing 11 behind the tape when the cartridge is in operative position on base 39. The light source or lamp 46L may also be "automatically retractable to clear the tape if necessary and is .used to highlight the markings on the tape or pass light thru the eutouts therein. Y v A In FIG. 4 is shown means for punching holes in a paper or plastic tape 21 while disposed in a magazine l0. While the housing 11 thereof is securely held in a clamp or frame 31. A plurality of punches or marking tools are shown secured to a block 48 and each comprising a solenoid or fluid cylinder 49 adapted to project a shaft 50 thereof containing a punching die or printing marker adapted to engage the tape when actu ated and provide cutouts or markings therein as codes. In other words, the devices 49 are arranged as a bank and each operative to project and retract a respective finger or punch 50 which is aligned with a respective channel or track of the tape. The devices 49 may comprise solenoids, air or hydraulic cylinders or servo motors which are operated by electrical or of reading switches or contact elements of the type illustrated in FIG. 1. The magazine housing 11 isreceived by a pair of flanged tracks 51 and 54 each of which has flared end portions 52 and 55. and stop end portions 53 and 56 at the other ends thereof for prepositioning the open edge with respect to the reading bank 57. U n

FIG. 7 illustrates a tape reading device including amount or housing 39'for respective flanged brackets 5 I I7 the housing 11 moved normal with respect to the sidewall of housing 39'.-as illustrated by the direction of arrow A. Flared side portions 52' and 55 of the bracke s 51' and 54"facilitate receipt of .the housing of 11' and side flanges 53 and 56 of said brackets preposition 11' with respect to a mount 58 fora bank of reading transducers such as photomultipliertubes or the like.

Whereas in the arrangement of FIG. 7 the shafts of the tape reels mounted within the magazine 11 may be pushed to en gage the ends of drive shafts of respective servo motors mounted within housing 39' for coupling thereto the arrangement illustra ed in FIG. 6 does not permit simple engagement of the shafts of the tape reels with driving means therefore.

Accordingly,'in FIG. 8 means are provided for automatically coupling the drive shafts of the servo motors used-to drive the reels situated within the tape housing with the shafts of reels after the cartridge is predeterminately located in operative relationship with respect to housing 39. A drive motor 59 is illustrated in FIG. 8 having its housing movable longitudinally within a slide bearing 65 supported by the walls of housing 39. A solenoid 63. is mounted against the front wall'39a of housing 39 and has an actuator. arm 64 which engages an extension 59' of the housing for motor 59. Thus, when the arm 64 of the push-pull solenoid 63 is operative to retract, it moves motor 59 and its shaft in a direction to 'efl'ect coupling of an end fitting 61 mounted on shaft 60 with arf end fitting 23' mounted v v on the shaft 23 of tape reel 20.Thereafter motor 59 may be operative to effect rotation of its shaft60 in a bearing supported in a housing 62 secured to wall 390 for rotating the reel 20 and driving the tape past the housing 58 for the bank of FIG. 9 shows an end'view of the'arrangement of FIG; 4

3 wherein the projecting die-punch members 50 are arranged 'to fluid pulses fed to each on respective input lines 51 which are respective tracks of the tape 21, by spark generating electrodes or other suitable means for in the tape.

Notation 47 of FIG. 4 refers to a bucking 'means in the form of a bar or plate attached either to the walls of the magazine 11 or the base 39 on which mount 48 is supported and positioned so as to be disposed immediately behind the tape 21 in alignment with the projectable elements of devices 49 to support the tape when it is punched or marked on. The device 47 may comprise a rigid bar or projection or a resilient member stationarily mounted or rotatable to cooperate with the projectable member 50 or a printing wheel replacing the marking device 49. Backing means 47 is preferably provided with a plurality of apertures associated and aligned with the projecting punching elements.

In FIG. 5 is shown an arrangement of printing or punching devices 49 which are staggered so as to permit close lateral spacing of the marking elements of each across the tape. Any staggered arrangement of the solenoids or fluid cylinders 49 may be effected provided that the inputs 51 to each are providing marks or cutouts pierce tape 21 and at least partially enter the openings prov vided in backing plate 66. g

FIG. 10 shows an alternative arrangement for reading information into tape 21 in electrostatic fashion. A backing plate 67 immediately beneath tape 21 is electrically grounded at 68. The support housing 58 is providedwith a plurality of electrodes 36 which are selectively pulsed with a relatively high voltage signal creating a spark across the relatively small gap between electrodes 36 and grounded plate 67. In a modified form of the device of FIG. 10, it may similarly be used for reading recording on the tape 21 by employing flexible sensing fingers which bear against tape 21 and, by momentarily protruding through associated punches in tape 21, complete an electrical circuit indicative of one binary state.

FIG. 11 shows another preferred embodiment in which the switches 36' are each comprised of a sensing finger 37 which is biased toward the tape and will close a circuit (contained within the switch housing) when momentarily entering a hole punched in the tape.

FIG. 12 and 13 illustrate a modified form of the invention in removably securable against a wall of a housing of a reader. or

scanner 39forl the tape in the cartridge and means associated properly energized to provide the proper markings or cutouts with the reader housing are operative thereafter for engaging the tape in order to drive same and/or control tension in the tape as it is driven and, in apreferred form of the invention, when the direction of movement of the tape is reversed.

Conventional tape transport devices which require manual threading of tape, include means for longitudinally pulling the tape during its acceleration and/or reverse movement of the tape so as to maintain a constant tension on the tape and prevent the tape from slackening in a manner which would d 54' which 'are vertically spaced apart to receive a magazine II. which is prevent it from being properly read. Slack may be taken up during the longitudinal movement of the tape by engaging the tape and displacing it normal or oblique to the longitudinal movement of the tape, the displacement being controllable by preset means or means responsive to an electrical signal generated when a sensing means senses the relaxation of tension in the tape.

In FIG. 12, the tape cartridge 70 is shown predeterminately positioned on the tape transport or reader housing 39 by the means hereinbefore described with the shafts l9 and of the reels 19 and 20 coupled to the drive shaft means associated with the reader 39 as described. The tape magazine 70 includes a housing 71 having sidewalls, one of which 72 is shown while the other is removed in FIG. 12 so as to reveal the contents of the housing. Lower and upperend walls 74, 75, and a rear wall 73 join said side walls and the front wall of the housing is defined by wall portions 76 and 76' which extend only a short distance from the upper and lower walls so as to define an opening to the housing 71 through which the tape 21 may be moved as illustrated in FIG. 13.

When the magazine 70 is first positioned against the sidewall of housing 39 by the positioning pins 391 or the means hereinbefore described, the portion of tape 21 passing through the open portion 70' of the housing which is defined by recesses in the sidewalls of the housing, is positioned, as shown, ofi the bank of transducers 83 and between respective pairs of rollers designated by notations 87, 88 and 87', 88'. The pairs of rollers 87, 88 and 87, 88 are automatically operative thereafter whereby at least one roller in each pair moves normal to the tape to engage same against the other roller for longitudinally drivingsaid tape and/or moving the tape in a manner to take up the slack thereof in response to the variations in the tension in the tape and/or acceleration or reverse drive of the tape.

The tape 21 is shown feeding from the periphery of the coil formation thereof provided on reel 19 to a first idler 77 and then around the inside of asecond idler 78 which is disposed closer to the opening than 77 and around which the tape may be drawn by the movement of roller 88 in a direction outwardly from the magazine housing 71 as shown, for example, in FIG. 13. Supported by the housing '82 of the transducer assembly 81 is a bar 84 which rotationally supports a pair of free wheeling rollers 85 and 85' at the ends thereof which guide the tape 21 in movement past the transducer head bank 83 while the tape is drawnout of the recess portion 70' of the housing 70 as illustrated in FIG. 13. The movement of rollers 88 and 88', which may be capstans or depressor rolls, outwardly from the housing 70 as illustrated in FIG. 13 may be operative to drawn the tape against rolls 85 and 85' and preposition same with respect to the transducer bank 83 as illustrated in FIG. 13 for operatively coupling the tape and the transducers thereof for performing the functions of reading and/or recording on the tape and predeterminately positioning the tape in operative relation to the transducers of bank 83.

Rollers 87, 88 and 87', 88' are supported on respective shafts, at least two of which are driven by respective drive motors or are free wheeling depending on the mode of tape drive to be employed. The shafts of each pair of rollers are guided in respective paths substantially normal to the surface of the tape defined by slotted openings 86 and 86' in the sidewall of housing 39 which extend a sufficient degree away from the housing 71 to pennit the tape to be drawn a predetermined degree out of the housing as illustrated in FIG. 13.

When reading or recording on the tape has been terminated and it is desired to replace the magazine 70 with another magazine, the rollers 87, 88 and 87', 88' are driven by servo motor operated means (not shown) or spring returned to the positions illustrated in FIG. 12 while the servo driving reels 19 and 20 are operated to either return all of the tape to the supply reel or to merely take up the slack in the tape so that it assumes the attitude illustrated in FIG. 12 and clears heads 83 as well as the rollers 87, 88, and 87', 88' permitting the magazine to be removed from the housing 39 without damage to the tape.

The transducer or bank of transducers 83 may comprise any suitable means for reading or recording on the tape such as those described or other means such as magnetic recording and/or reproduction heads, assuming that the tape 21 is magnetic recording tape.

Two other means for controlling tape tension or eliminating the difficulties encountered by slackened portions of the tape are illustrated in FlGS. 14 and 15. in FIG. 14 the tape 21 has been driven out of the magazine housing 71 by a powered roller 88a which is operatively connected to a servo motor and means for moving the shaft thereof along a slotted hole 86a in the sidewall of the tape reader housing 39. Powered roller 88a moves the tape 21 into alignment with the open end of a subhousing 89 which defines a long column, the lower end of which is connected to a vacuum pump to reduce the pressure therein for the purpose of maintaining tension on a looped portion of the tape defined in FIG. 14 by the notation 21a. The sidewall 90 of column 89 has a width substantially equal to the width of the tape so that when air is drawn from the lower end 89' of column 89 by connecting a vacuum pump to a tube 93 coupled thereto, the tape loop 21a will be drawn into the column and maintained therein under constant tension even if it is in motion along the path defined by the various tape guide means associated with the magazine and the reader housing 39. Wheel 88a may be merely operative to position the tape 21 in alignment with the open end of the housing of column 89 whereafter the tape may be drawn by air pressure into the housing or the wheel 88a may be operative to rotate upon aligning the tape with the open end of the column 89 so as to drive sameinto said column as shown after which the wheel 88a may be retracted to permit the movement of the tape without interference thereby. Notations 91 and 92 refer to the rounded upper ends of the wall 90 of the column 89 to permit the tape to be driven thereover without excessive wear on the tape with the tape blocking off volume 89' of column 89.

FIG. 15 illustrates a modified form of the invention in which wheel 88a draws the tape immediately above the open end of column housing 89 against an idler wheel 94 which cooperates with 88a in driving a portion of the tape into the column 89. In FIG. 15 the column 89 is shown as receiving looped portions of the tape to provide substantial slack within the column when operated without applying suction to the bottom of the column so that the downstream portion 21 of the tape may be driven from the slack portion thereof situated within the housing 89.

Variations in the tape magazines and the transducer and transport means hereinbefore described are noted as follows.

The multiple feed and takeup reels for the tape may be replaced by an endless loop of tape and means for maintaining same in a spiral coil formation within the magazine housing whereby the tape slack takeup or drive means described or modifications thereof may be provided to operate on the tape as described.

It is also noted that certain of the features of the invention illustrated in FIGS. l2-l5 may be applied to the embodiments illustrated in the figures 18 for reading and/or recording on tape mounted on a magazine or cartridge.

Various forms of recording and scanning may be employed by using the proper transducers cooperating with the tape by the means described. For example, signals may be magnetically recorded and reproduced from steel or plastic tape containing magnetic oxide, thermoplastic recording means such as one or more electron guns generating beams for scanning the predeterminately positioned tape and optical scanning means may also be utilized. The recording transducers may also comprise reciprocating printing means and/or rotary printing wheels selectively operable to engage the tape as it is driven.

The described rollers operative to engage and draw the loop of tape out of the cartridge may be replaced by other means such as fingers, suction devices or the like operative to engage and hold the tape and to move along slotted guides as described or on pivoted and/or lineally actuated arms.

Automatic means for loading and unloading tape cartridges on the reader may be provided.

Also, banks of side-by-side arrayed cartridges as described may be serviced by a single bank of recording and/or reproduction transducers in one or more of the forms as described wherein the arrayed cartridges are selectively movable to position a selected cartridge in operative relation with said bank of transducers or the means mounting the bank of transducers is selectively movable to bring said transducers' into operative relation with a selected cartridge to perform the transducers described are noted and are illustrated in FlGS. 8

and 11. In FIG. 8, the mount 58 for the photoelectric reading transducers is shown as being pluggable and connectable against the sidewall 39a of the reader housing 39 toperrnit quick replacement thereof. Wire pairs extending from the reading transducers 46 mounted in 58 are shown'connected to male connector plugs 42 mounted onthe wall of the housing 58 which engages the wall 394. Plugs 42 engages female receptacles 43 mounted on wall 390 each of which receptacles is connected to a respective wire of a bundle 46' thereof which extends to the output or computing circuits of the reader device 39. Screws or quick-connect fasteners (not shown) may be used to fastening subhousing 58 to the main housing so that it may be easily removed and replaced if necessary.

In FIG. 11, the bank 36' of switches or feeler contact anns 37 is shown secured to a mount 70 which is removably secured to housing 39 with screws S. Pluggable leads. extending from the transducers of bank 36 such as illustrated in FIG. 8 may also. be employed in the arrangement of FIG. 1 l to permit quick disconnection and replacement of the bank of transducers or switches.
