  • Patent number: 7565855
    Abstract: A sales slip printer for segments (26) that are to be separated from a continuous paper strip (14) with a V-shaped knife (18) and a stacking tray (24) for the segments (26) separated from the continuous paper strip (14) located behind an output channel (12), which is separated from the output channel (12) by projections (28) extending in the side edge areas of the output channel (12), and a slide (30), which pushes through the already separated edges of the continuous paper strip (14) into the stacking tray (24) between the projections (28) during a cutting action.

  • Patent number: 6637959
    Abstract: Printing device with means for conveying paper A printing device (10) comprises a lower part (12) and an upper part (14) that is mounted on said lower part (12) such that it can pivot about a pivot axis (16). A print head (18) and a holding trough. (62) for a recording medium supply roll (64) are arranged in the lower part (12) , and a conveying device (24, 30) for a recording medium (66), and a print backing support (36) spatially associated with the print head (18) are arranged in the upper part (14). The upper part (14) has two side walls (42) which laterally enclose a recording medium supply roll (64) put into the holding trough (62).

  • Patent number: 6059471
    Abstract: A device for transporting a sheet (18) to be printed in a printer is described, with a carriage (14) which is designed for receiving the sheet and which can be displaced on a fixed stand (12) perpendicularly to the line direction between a starting position for inserting and removing the sheet and an end position moved into the printer. Mounted on the carriage (14) is a releasable clamping device (26) which comprises a bearing surface (22) for the sheet (18) and a clamping lever (35) spring-loaded in the clamping direction. The latter is provided with an actuating cam (48) which co-operates with a control bar (40) provided on the stand (12), in such a way that the clamping device (26) is opened in the starting position, closes after this starting position has been passed in the direction opposite to the end position and opens again when the carriage (14), coming from the end position, reaches the starting position.

  • Patent number: 5613788
    Abstract: A cutting device for cutting a print carrier in a printer (10), especially in a till printer, has a blade (22) which is movable along at least one guideway (28) against a fixed counterblade (24) and which, in an open setting, frees an opening (20) to allow the printer carrier to be passed through and, in a closed setting, has at least partially cut through the print carrier. The blade (22) can be moved between the open setting and the closed setting by an adjusting mechanism. The blade (22) has at least two guide elements (38), which are disposed at a distance apart on the side facing away from the cutter (42) of the blade (22). The adjusting mechanism (30) engages in the guide elements (38) in order to adjust the blade (22).

  • Patent number: 4822189
    Abstract: A drive arrangement for an ink ribbon cassette or the like having a transport roll arranged inside of the cassette permits the cassette to be inserted and ejected in a direction perpendicular to the transport roll axis relative to the receiving compartment of a ribbon device and also provides an automatic coupling between the transport roll and a drive shaft forming part of the device. The drive shaft is shiftable between a coupling position and a decoupling position set back from the coupling position against the force of spring means. On the forward end of the cassette as it is inserted perpendicular to the transport roll axis is a ramp which during the inserting movement of the cassette runs against the drive shaft and pushes it to its decoupled position. When the cassette reaches its fully inserted position the drive shaft automatically catches into the transport roll. Special actuating means are provided for decoupling the drive shaft from the transport roll.

  • Patent number: 4651609
    Abstract: The invention relates to a device for selectively notching or severing a paper strip (18), e.g. a cashier's bill, in a printer. The cutter (2) is pushed to and fro by means of a sliding block (38) arranged on it by way of a pivot, which block engages in a slide track (28). The sliding block (38) can assume two different angular positions in the slide track (28), in which the pivot (36) connecting the slide block (38) with the cutter (2) is located either radially inside or outside of the center line of the slide track (28), so that the cutter (2) reaches different end positions, in one of which the paper strip (18) is notched and in the other of which it is severed. The setting of the different angular positions of the sliding block (38) takes placed automatically through a choice of the rotation direction of the crank disk (26) showing the slide track (28).

  • Patent number: 4642449
    Abstract: The invention relates to a cashbox for a cash register, with a money drawer mounted in a cash case so as to be slidable in a moving-in and a moving-out direction, a sliding drive for the money drawer with spring means which act on the money drawer, are stressed when the latter moves in, and supply the force for moving the money drawer when it has moved in and also a lid operationally connected with the money drawer which lid swings open when the latter is moved out and swings shut when it moves in.

  • Patent number: 4638908
    Abstract: An insert for a money drawer for receiving coins, currency, bills and the like including a relatively large area lower tray defining a plurality of relatively long and relatively deep compartments running from front to rear of the lower tray and sized to accommodate paper currency, a relatively small area upper tray defining a plurality of relatively short and relatively shallow compartments running from front to rear of the upper tray and sized to receive metal currency, and coacting means on the lower tray and on the upper tray for removably mounting the upper tray in the upper rear region of the lower tray so that the upper tray overlies the rear portions of the relatively long currency compartments defined by the lower tray.

  • Patent number: 4637326
    Abstract: A money box arrangement particularly for use in the cashier's stations of department stores, on bank counters or the like is proposed. This money box arrangement in particular will make possible a simple and secure carrying of the money between the cashier's station and a central cash office. It comprises a cash insert (10) which can be taken out of the cashbox (4) of a cash register (2), a portable strongbox (12) for receiving the cash insert (10) as well as other reserve money not located in this place, and moreover comprises a cover (14) which can serve for closing off the cash insert (10) and for closing off the portable strongbox (12). This arrangement makes it possible for the change in the cash insert (10) and the reserve money to be carried securely between the cashier's station and the central cash office.
