摘要:
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. The drive arrangement is especially useful for the ink ribbon cassettes of printers.
