By selectively operating the solenoids, the control plates can be positioned to provide a plurality of different movements for the sensing member.
- FIG. 1 is a side view of the record material feeding mechanism.
- FIG. 2 is a detailed plan view of a receipt member showing the data of the merchandise transaction.
- FIG. 3 is a schematic representation of the timing operation of the printing of various types of data on the receipt member and the paper feed cam member.
- FIG. 1 there is shown a side view of the record material feeding mechanism of the present embodiment which is located within an electronic cash register or data terminal device 20.
- the feeding mechanism includes a drive roller 21 rotatably mounted on a stud 22 secured to the framework of the terminal device 20.
- a pressure roller 23 rotatably mounted to the framework of the terminal device coacts with the drive roller 21 to engage and drive a ribbon of receipt paper 24 upon which is printed the data of the transaction.
- the receipt paper 24 is moved from a supply roll 25, rotatably mounted to the framework of the device, over a system of rollers 26, past a printing station 27 which prints the data on the receipt paper 24, past the roller 28 to the drive roller 21.
- the drive roller 21 moves the receipt paper 24 past a knife mechanism (not shown) which cuts the receipt paper to provide a receipt 30 (FIG. 2) which is given to the customer.
- the receipt 30 has printed thereon data 31 concerning each item transaction, a total transaction 32, a consecutive number 33, the date 34 and a logo 35 which is the same on each receipt 30.
- the drive roller 21 is required to provide a long feed of the receipt paper 24.
- the logo 35 is automatically printed on the receipt paper.
- the drive roller 21 will provide a short feed. When a feed distance is required which falls between the distance obtained by a long and short feed operation, a middle feed of the receipt paper 24 will be selected. When a non-print operation occurs, a non-feed is required of the drive roller 21.
- the selection of the type of operation the terminal device 20 is to perform is controlled by a set of transaction keys 36 located on the keyboard of the device.
- the depression of the appropriate transaction key 36 will control the length of the feed of the receipt paper 24 in a manner which will now be described.

- a spring clutch 40 Connected to the feed gear member 38 through a spring clutch 40 is a sector pinion 41 which is engaged and rotated by a sector member 42.
- the spring clutch 40 will allow the sector pinion 41 to rotate the feed gear 38 only in a counterclockwise direction as viewed in FIG. 1. Clockwise rotation of the pinion 41 will disengage the spring clutch 40 from engagement with the feed gear member 38.
- the sector member 42 is rotatably mounted on a stud 43 secured to the framework of the terminal device 20.
- a spring 44 mounted between a stud 45 on the sector member 42 and a stud 46 in the framework of the terminal device normally urges the sector member 42 in a counterclockwise direction and the sector pinion 41 in a clockwise direction.
- the lower end of the sector member 42 is pivotally connected to one end of a link member 47, the other end of which is rotatably secured to one end of a feeler member 48 rotatably mounted on a stud 50 secured to the framework. It will be seen from this construction that rotation of the feeler member 48 will produce a like rotation of the sector member 42.
- a motor operated cam shaft 51 to which is mounted a cam member 52.
- a cam follower arm 54 Rotatably mounted on a stud 53 secured to the framework of the terminal device is a cam follower arm 54 to which is rotatably mounted a pair of rollers 55 which in turn engage the peripheral surface of the cam member 52.
- Rotatably secured to the arm 54 is a link member 56 which, under the action of a spring 57 mounted between the stud 46 and a finger portion 58 of the link member 56, will normally rock the arm 54 and rollers 55 clockwise into engagement with the cam member 52.
- the other end of the link member 56 is pivotally connected to one end of a feed arm 60 which in turn is rotatably secured to the framework, the other end of the feed arm 60 being positioned adjacent a stud 61 mounted on the sector member 42. It will be seen from this construction that movement of the link member 56 to the left as viewed in FIG. 1 will rock the feed arm 60 counterclockwise resulting in the clockwise rotation of the sector member 42. As will be described more fully hereinafter, the clockwise rotation of the sector member 42 will result in the drive roller 21 feeding the receipt paper 24 a distance commensurate with the length of rotation of the sector member 42.
- the feeler member 48 (FIG. 1) has a bent over sensing surface 62 which is positioned adjacent a pair of control plates 63, 64 rotatably mounted on a stud 65 secured to the framework of the terminal device.
- the control plate 63 includes a pair of control surfaces 66, 67 while the control plate 64 includes the control surfaces 68, 70.
- the control plate 63 has mounted thereto a stud 71 located adjacent to and in the plain of movement of the control plate 64 and a second stud 72 to which is secured one end of a spring 73.
- the spring 73 normally urges the control plate 63 in a counterclockwise direction as viewed in FIG. 1.
- This rotational movement of the plate 63 by the spring 73 is controlled by a latch member 73 which is rotatably mounted on a stud 75 secured to the framework and located adjacent the control plate 63.
- the latch member 74 has a hook portion 76 which normally engages a bent over foot portion 77 of the control plate 63 holding the control plate in a home position against the action of the spring 73.
- a spring 78 mounted between a stud 80 located on the link member 47 and a finger portion 81 of the latch member 74 normally urges the latch member in a counterclockwise direction into engagement with the foot portion 77 of the control plate 63 and against the action of the spring 73.
- the other end of the latch member 74 is engaged by one end of a rotatably mounted armature member 82, the other end of which is located adjacent an associated electromagnetic member 83 mounted to the framework of the terminal device by means of screws 84.
- Energizing of the electromagnetic member 83 will rock the armature member 82 counterclockwise as viewed in FIG. 1 which in turn rotates the latch member 74 clockwise against the action of the spring 78, thereby releasing the control plate 63 to the action of the spring 73.
- control plate 64 There is associated with the control plate 64 a similar arrangement which includes a spring 79 for rotating a latch member 85 which normally latches a foot portion 86 of the control plate 64 under the action of a spring 87.
- An armature member 88 associated with an electromagnetic member 90 engages the end of the latch member 85 and operates to rock the latch member 85 clockwise against the action of the spring 87 upon energizing of the electromagnetic member 90.
- the cam shaft 51 (FIG. 1) is rotated 360 during the printing of each line of data on the receipt 30 (FIG. 2).
- FIG. 3 there is shown a schematic diagram of the timing of operation of various mechanisms which occur during a printing operation.
- the data to be printed is set up on typewheels (not shown) located in the printer 27.
- the logo 35 (FIG. 2) is printed on the receipt paper 24.
- the feeding of the receipt paper is made.
- the feeding of the receipt paper is controlled by the length of rotation of the sector member 42.
- the cam 52 (FIG. 1) will rock the cam follower arm 54 first clockwise and then counterclockwise between 280 and 330 of rotation of the cam shaft 51.
- the clockwise rotation of the arm 54 about the stud 53 will rock the feed arm 60 in a clockwise direction allowing the sector member 42 to be rotated counterclockwise by the spring 44.
- This movement of the sector member 42 is normally limited by the engagement of the stud 61 against the arm 60.
- Counterclockwise rotation of the sector member 42 will rotate the pinion 41 but not the gear 38 due to the spring clutch 40 connection.
- the cam 52 will rock the cam follower arm 54 in a counterclockwise direction allowing the arm 60, through its engagement with the stud 61, to rock the sector member 42 in a clockwise direction against the action of the spring 4.
- This clockwise rotation of the sector member 42 will rotate the gear 38 and the drive roller 21 through the gear 37 by the action of the spring clutch 40 on the gear 38.
- the clockwise rotation of the drive roller 21 will feed the receipt paper 24 due to the coaction between the drive roller 21 and the pressure roller 23 in a manner well known in the art.
- the length of feed of the receipt paper 24 is dependent on the length of rotation of the sector member 42 in a clockwise direction.
- This length of clockwise movement as controlled by the action of the feeler member 48 in sensing one of the sensing surfaces on the control plates 63, 64 as the sector member 42 is being moved counterclockwise by the spring 44.
- the sensing surfaces 66 and 67 of control plate 63 control a middle feed and non-feed operation respectively while sensing surfaces 68 and 70 of control plate 64 control a short and long feed operation respectively.
- neither of the electromagnetic members 83, 90 are energized resulting in the positioning of the control plates 63, 64 in the position shown in FIG. 1.
- the feeler member 48 will be rotated in a counterclockwise direction allowing the sensing surface 62 of the feeler member 48 to engage the surface 68 of the control plate 64 thereby selecting a short feed.
- This movement of the feeler member 48 will condition the sector member 42 to rotate the pinion gear 41, feed gear 38 through the action of the spring clutch 40, gear 37 and drive roller 21 so that the receipt paper 24 is moved through a distance commensurate to the sensing movement of the feeler 48. As shown in FIG. 3, this short feed movement occurs between 280 and 330 of rotation of the cam shaft 51.
- the electromagnetic member 90 When a total print operation is selected, the electromagnetic member 90 is energized resulting in the clockwise rotation of the latch member 85 by the armature 88 and the releasing of the control plate 64 to the action of the spring 79.
- the spring 79 will rotate the plate 67 clockwise until it is stopped by a stud 91 mounted on a link member 92.
- the sensing surface 62 of the feeler 48 In this position of the control plates 63, 64, the sensing surface 62 of the feeler 48 will move down between the control plates until it engages the surface 70 of the control plate 64. This movement constitutes a long feed of the receipt paper 24 by the rollers 21, 23.
- the electromagnetic member 83 When a non-feed condition is required, such as occurs in a non-print operation, the electromagnetic member 83 is energized, thereby releasing the control plate 63 to the action of the spring 73.
- the clockwise movement of the plate 63 is limited by the engagement of the stud 71 on the control plate 63 with the control plate 64. This movement will position the surface 67 of the control plate 63 adjacent the sensing surface 62 of the feeler 42, thus preventing any clockwise movement of the feeler 42.
- both of the electromagnetic members 83, 90 will be energized. Energizing of the member 83 will result in the control plate 63 being rotated counterclockwise by the spring 73 until the stud 71 engages the edge of the control plate 64. Energizing of member 90 will allow the spring 72 to move both control plates 63, 64 counterclockwise until the control plate 64 engages the stud 91. In this latter position, the surface 66 of the control plate 63 will be sensed by the surface 62 of the feeler 48, thus providing a middle feed movement of the drive roller 21. After each feed movement, the control plates 63, 64 are rotated in a clockwise direction to their home position by the stud 91.
- This restoring movement is controlled by the cam shaft 51 in which the link 92 is cam actuated for rotation about a stud 93 in a clockwise direction to allow the stud 91 to return the control plates 63, 64 to their home position wherein the latch member 76, 85, under the action of their springs 78, 87, will latch the control plates in their home position as shown in FIG. I.
