Claims

[Claims for Utility Model Registration] (1) A substantially U-shaped ink ribbon that removably holds an ink ribbon cassette, which is made by extending a wide ink ribbon such as a field-sequential type ink ribbon between a pair of reel cores held in a cassette case. The ink ribbon cassette has a mount frame, a spool that engages with a take-up reel core of the ink ribbon cassette is attached to one side plate of the mount frame, and the ink ribbon is wound up by rotating the spool with a motor. In the hoisting device, a spool rotation shaft is formed integrally with the spool so as to extend through the side plate of the mount frame to the outside thereof; a cylindrical spur gear fixed to the rotational drive shaft of the motor so as to be parallel to the spool rotation shaft; 1. A winding device for an ink ribbon cassette, comprising: a drive gear attached to the spool; and friction clutch means interposed between the drive gear and the spool rotating shaft. (2) In claim (1) of the utility model registration, the friction clutch means includes a clutch plate attached to the spool rotating shaft so as to rotate therewith, and a link between the clutch plate and the drive gear. 1. A winding device for an ink ribbon cassette, comprising a friction plate made of felt or the like disposed on the ink ribbon cassette. (3) In claim (1) of the utility model registration, a first spring is provided between the holding member and the spool to bias the spool inward of the mount frame. The ink ribbon cassette winding device is further characterized in that a second spring is installed between the spool rotating shaft and the drive gear to press the drive gear toward the friction clutch means. (4) In claim (2) of the utility model registration, the clutch plate has a cylindrical portion that is fitted onto the spool rotation shaft, and the holding member slides on the spool rotation shaft via the cylindrical portion. A winding device for an ink ribbon cassette, which is capable of movably holding an ink ribbon cassette.
