In a replaceable ribbon cartridge (12) for printers in which the ribbon (14) can be guided out of the cartridge through an exit opening (16) and at the end of a tension segment extending outside the cartridge can be reintroduced into the cartridge through an entrance opening (18), there is arranged on the cartridge (12) in the zone of the tension segment at least one deflection slide (24, 26) displaceable in a direction approximately perpendicular to the ribbon plane between a position of retraction into the cartridge (12) and an extended position deflecting the ribbon (14). Through the deflection slide or slides (24, 26), the ribbon (14) is generally spread away from the cartridge sufficiently so that upon insertion of the cartridge into the printer, it places itself around the printer head. During the last phase of insertion, the deflection slides (24, 26) are retracted, as by means of rams (56) arranged on the printer, so that during the subsequent ribbon advance, the ribbon (14) can become tensioned in its guide.

Replaceable ribbon cartridge for printers

Printing or recording apparatus for the selective printing of single sheets or margin-perforated endless paper in which for the endless paper operation a separate conveying unit can be put in place on the printer housing which unit is provided with conveying means engaging in the perforated margin of the endless paper. The sight case of the conveying unit is arranged over the feed opening as well as the delivery unit for the single sheets. A movable lid permits access to these openings for the single-sheet operation but covers these completely and in a soundproofing way for endless paper operation. Connected with the movable lid there is a prop which in the closed position of the lid automatically lifts off the platen the feed rolls not required in this operating state.

Printing and typing apparatus for the selective printing of single sheet

Printing apparatus with a roller platen and a plastic strip for holding paper against the roller platen even if insufficient paper is fed through to reach the usual guide rollers. The plastic strip is arranged in a closed loop and is connected to the print element to move with it in the line direction. The strip has a perforation for the penetration of printing type or the like.

Printing or typing apparatus with a rotating platen as well as guide

Apparatus for guiding an ink ribbon for a printer, with top edges standing perpendicularly to and inclined forward toward the printing plane, over which the ink ribbon laid on flange plates which act as slides when fed further and threads in itself. At the same time means for the quick fixing of the print head are provided on the apparatus serving for the guiding of the ink ribbon.

Device for the mounting of a printing head and for the mounting and

A magazine for a cash dispensing machine including a lock which can be activated at a loading station to trip if later tampered with thereby to prevent installation of the magazine.

Portable certificate magazine

A spring clutch for a step drive, such as for form feeds in office machines, comprising drive and driven hubs rotatable about a common axis and having respective axially adjacent parts surrounded by a coil torsion spring which, in an unstressed condition, has a diameter greater than that of the hub parts, the spring having one end anchored for rotation with the drive hub, and the other end coupled to a clutch actuating member through the intermediary of a slip clutch mechanism having a slip torque which is greater than the torque required to wind the coil torsion spring onto the hub parts.

Wrap around spring clutch

An intermittent drive for a single-element printing typewriter, calculator or similar machine. The drive comprises a drive shaft couplable via a cycle clutch to a driven shaft and a governor disposed on the driven shaft to couple it with and maintain it at the same speed as the drive shaft during the clutch cycle. The governor comprises a friction wheel having a generally circular cross-section provided with flattened portions. During the clutch cycle, when the clutch engages the driven shaft, the friction wheel contacts a roll fixed to the drive shaft preventing the driven shaft from leading the drive shaft in response to reflected forces. At the end of the clutch cycle, when the clutch is disengaged, the friction wheel has rotated so that a flattened portion of the friction wheel faces the roll, and driven shaft is free from the rotation of the drive shaft.
