Oderman et a1 198/33 AB [451 July 10, 1973 Primary Examiner-Richard E. Aegerter Assistant Examiner.1ames W. vMiller Attorney-J. T. Cavender, Wilbert Hawk, Jr. and Richard W. Lavin 57] ABSTRACT A mechanism for positioning a record member on a platform, rotating the platform 180 and then removing the record member from the platform is disclosed. Included in the mechanism is a pair of drive rolls mounted on a rotatably mounted platform which en gages and positions a record member on the platform. The platform is then rotated during which movement the drive rolls are disabled. Upon reaching a 180 rotation of the platform, the drive rolls are again operated to remove the record member from the platform. A stationary drive member positioned adjacent the platform will alternately engage each drive roll upon the positioning of the platform in a horizontal plane.

14 Claims, 3 Drawing Figures ROTATING MECHANISM BACKGROUND OF THE INVENTION The present invention is utilized in a creditcard printer in which information is encoded on one side of the card in the form of color bars and on the other side in human readable form. The use of color bars to encode information on a tag or other type of record medium is fully disclosed in US. Pat. No. 3,671,722. To provide as high a rate of operation of the printing of the credit card as possible, the credit card is required to be moved from a display station where the information to be printed is read by an operator to a printing station where the information to be encoded is printed with the credit card being rotated to present the proper printing surface to the printing mechanism in as short a time as possible. In some instances the encoded information is to be printed on the same side as the human readable information is printed. Thus the card is to be tranported to the printing mechanism without rotation of the card occurring.

SUMMARY OF THE, INVENTION Therefore it is an object of this inventionto provide a mechanism for rotating a record member 180. It is another object of this invention to provide a mechanism for rotating and feeding a record member through a predetermined distance, which is simple in'operation, low in cost, and compact inconstruction. In carrying out these objects of the invention, there is provided a rotatably mounted platform on which are mounted a pair of drive rolls which coact upon the positioning of a record member therebetween. A stationary drive member positioned adjacent the platform engagesone of the driverolls when the platform is in a home position. Operation of the drive rolls will position a record member on the platform, thereby initiating a rotation of" the platform through 180 by 'a second drive means. Rotationof the platform will disengage the operated drive roll from the stationary drive member. Completion of the rotation of the platform will engage the other drive roll with the drive member resulting in the record member being driven from the platform. If the platform is not rotated, the drive rolls will feed the re- FIG. 1 is a front view of the rotating mechanism vshowing the drive rolls and the support guides.

DESCRIPTION OF THE PREFERRED EMBODIMENT Referring to FIG. 2, there is shown a side view of the rotating mechanism which. includes a triangular-shaped body member 20 (FIG. 3) to whichis mounted a constantly operating motor 21. The drive shaft 22 of the motor 21 will transmit the rotational movement of the motor by means of a hub member 23 pinned to the shaft 22 and a drive belt 24 to a second hub member 25 rotatably supported on a drive shaft 27 journaled in the body 20. A spring clutch 28 having one end secured to the drive shaft 27 is positioned adjacent the hub member 25..As will be explained more fully hereinaf- 2 ter, release of the spring clutch 28 will couple the rotation of the hub member 25 to the drive shaft 27.

A drive belt 30 (FIGS. 1 and 2) mounted on the hub member 25 will transmit rotation of the hub 25 to a I idler hub member 31 rotatably mounted on the body member 20 and to a hub member 32 pinned to a drive shaft 33 journaled in the body member 20. Pinned to the other end of the shaft 33 is a drive roll 34 which normally engages one of two drive rolls 35, 36 rotatably mounted on studs 37, 38 secured to a platform 40. The

platform 40 is secured to a shaft 41 (FIGS. 2 and 3) journaled within the body 20. Pinned to the shaft 41 adjacent the platform 40 is a gear member 42 which engages a second gear member 43 pinned to the shaft 27. It will be seen from this construction that rotation of the drive shaft 27 and gear 43 will result in the rotation of the platform 40. As shown in FIGS. 1 and 2, riveted to the front of the platform 40 are two sets of guide supports 44 which are separated by the drive rolls 35, 36. The drive rolls 35, 36 are mounted with their peripheral edges separated by less than the thickness of a record member such that the positioning of a record member onthe guide supports and between the rolls will allow one of the rolls which is being driven by the drive'roll34 to drive both-the rec-0rd member and the other drive roll. It is obvious that the feed rolls can be mounted to engage each other such that both rolls will be operated by the drive roll 34. This will depend on 41 is an arm assembly 45 having its free end rotatably secured to a plunger'46 of a solenoid 47. As shown more clearly in FIG. 2,-the arm assembly 45 has a pair of spread apart ends 52, 53 secured together. A spring 48 secured to the end of the plunger 46 normally urges the plunger 46 and the arm asesembly 45 in aclockwise direction upon the deenergizing of the solenoid 47. In this latter position, one end 52 (FIG. 2) of the arm assembly 45 will engage and hold one end 50' of the spring clutch 28 in a position which disengages the clutch from the hub member 25.

In the operation ofthe mechanism, the motor 21 will be operated continuously thereby rotating the hub member 25 and the drive roll 34 in the mannerdescribed previously. Upon'the positioning of a credit card within one set of the guide supports" 44 and into engagement with the drive rolls 35, 36, the credit card,

the photo-cells have sensed that the credit card has.

been positioned on the platform 40, the solenoid 47 (FIG. 3) is energized rocking the. arm assembly 45 counter-clockwise. This movement removes the end 52 of the assembly from engagement with the end 50 of the spring clutch 28 thereby releasing the spring clutch which couples the drive shaft 27 to the movement of the hub member 25. Rotation of the shaft 27 will, through the engagement of the gears 42, 43, rotate the platform 40 and the credit card through a l rotation. Initial rotational movement of the platform 40 will disengage the drive roll 35 from the drive roll 34 as viewed in FIG. 1, thus stopping the movement of the rolls 35, 36 and the credit'card. Upon completion of the movement of the platform 40, the drive roll 36 will engage the drive roll 34 resulting in the movement of the credit card off the platform. As the credit card is being transported from the platform, another credit card is being positioned within the guide plates 44 preparatory to another rotational operation. It will be seen from this construction that the rotation of the credit card consumes very little time in the movement of the card between printing stations and that the movement of the card on the rotating mechanism is a by-product of the operation of the rotating movement. It should also be pointed out that the rotation of the credit card occurs within its own length which provides for a very compact construction.

After the solenoid 47 has been energized to release the spring clutch 28 as described previously, the solenoid will be immediately deenergized thereby allowing the spring 48 to rotate the arm assembly 45 clockwise as viewed in FIG. 3. The movement of the arm assembly 45 will bring the end portion 53 of the arm assembly into engagement with a cam surface 51 (FIGS. 2 and 3) which is secured to the shaft 27. At this time, the cam surface 51 will prevent the arm assembly 45 from moving to an engaging position with the end 50 of the spring clutch 28. Upon the completion of one revolution of shaft 27, the cam surface 51 will position the end portion 52 ofthe arm assembly 45 into engagement with the end 50 of the spring clutch 28, thereby disabling the spring clutch from engagement with the hub member 25. This action disengages the shaft 47 from the hub member 25, thus stopping the platform 40. With this construction the platform 40 can only be rotated through 180 upon each operation of the solenoid 47.

under certain conditions, the operator will want to encode the information in color bars on the same side of the credit card as the human readable information is located. When this is to occur, the operator will interrupt the energizing circuit to the solenoid 47 which allows the drive roll 34 to continuously operate the drive rolls 35, 36 thereby transporting the record card through the guide supports 44 on the platform 40 to the printing station. Thus the mechanism functions as a transport mechanism irrespective of whether a rotation of the card is required.
