Claims

[Scope of utility model registration request]

A side plate is provided to rotatably support one end of two parallel rotating shafts, at least one of which is driven by a drive unit, and a pair of side plates are provided which hold the ribbon in a wound state from both ends and are respectively fitted to the rotating shafts. A ribbon cassette having a spool is provided, a guide shaft is provided at one end of which is held by the side plate and guides the ribbon from the spool on the supply side to the printing section, and a light emitting element and a light receiving element are arranged facing each other with the ribbon in between. A detector having one end fixed to the side plate is provided at a position upstream of the guide shaft, and a rotation fulcrum located near the upstream side of the detector and abutting the ribbon, a ribbon guide that guides the ribbon in a straight line between the light emitting element and the light receiving element and around the outer periphery of the guide shaft; A pressing body is provided so as to be rotatable, one end of which is fixed to the side plate, and which comes into contact with the ribbon guide and retracts the ribbon guide from the ribbon when the rotating shaft and the spool are fitted together. Ribbon guiding device.
