カートリツジの駆動機構。[Claims for Utility Model Registration] (1) A printing device having a reciprocating carrier, a printing head mounted on the carrier, and a removably installed ink ribbon cartridge containing an ink ribbon, The carrier is rotatably provided with a drive shaft capable of engaging with the feed roller of the carriage, a first gear is mounted on the drive shaft, and a main shaft is rotatably provided with a second gear on the carrier. A third pulley is fixed to the main shaft and is supported by a rope stretched in the direction of movement of the carrier, and is always in mesh with the second gear and is swingably supported. and a fourth gear are provided in a form that meshes with the third gear, and the third and fourth gears each include an arm that swingably rotates about a fixed point of the carrier by a rotation shaft. A third shaft is provided at a position sandwiching the fixed point above, and rotates in a specific direction depending on the rotational direction of the main shaft.
Alternatively, an ink ribbon cartridge drive mechanism is configured such that only the fourth gear meshes with the first gear and the drive is always rotated in a constant direction. (2) The ink ribbon cartridge according to claim 1, in which the rotational drive means comprises a pulley fixed to the main shaft and a rope wound around the pulley and stretched in the direction of movement of the carrier. drive mechanism.
