Abstract

PURPOSE:To reduce a play required for switching a transmission system at the time of reversing a carrier, by switching the operation of the transmission system through an axial movement of a gear on the transmission system side. CONSTITUTION:When a carrier is moved, a gear shaft 19 is moved downward under a thrust load. By the movement, a ratchet part 10a and a ratchet part 20a are engaged with each other, and a gear 20 is rotated. Therefore, a coupling shaft 16 is rotated, whereby a driving roller for a ribbon cassette 25 is driven to circularly move a ribbon contained in the cassette. When the carrier is reversed and is moved backward, the gear shaft 19 is moved upward under a thrust load, whereby the ratchet parts 19a and 22a are engaged with each other, and a gear 22 is rotated. Switching of operations of transmission systems 14, 15 is conducted by the axial movement of a gear 13 on the transmission system side, and the amount of the movement may be small, so that a play required for switching the transmission systems at the time of reversing the carrier is reduced.
