An exchangeably insertable ink ribbon cassette, for a printer has a storage space for an ink ribbon and a transport device for the ink ribbon that can be driven through a reduction driving gear by an electric motor. The liability to repair of the printer is reduced in that the electric motor (12) and the reduction gear (15, 16) are arranged in a drive housing (6) fixedly integrated with the housing of the ink ribbon cassette and means (7 to 10) are provided for establishing a current connection between the motor (12) and the printer by means of a detachable contact connection.

Exchangeably insertable ink ribbon cassette for a printer

A printing device and a carriage transport motor are mounted separately on a carriage and driven in a step-wise manner. The motor shaft rolls over a rubber guide at least under the influence of the weight of the motor, while a driving pinion on the shaft engages a rack.
