Claims

[Scope of utility model registration request]

(1) In a printer equipped with a carriage that carries a print head and a ribbon cassette containing an ink ribbon and moves back and forth, a gear plate rotatably supported by the carriage and coaxially connected to the gear plate are provided. A sangya which is rotatably supported, two planetary gears meshed on both sides of this gear and rotatably supported by the gear plate, and an idle gear connected to one of these two planetary gears. a blade bond drive gear that is integrally formed coaxially with the ribbon roller and rotatably supported by the carriage; and a gear break spring that elastically inhibits rotation of the two planetary gears. and a means for transmitting the reciprocating motion of the carriage to the rotational motion of the sangya.

(2) The means for transmitting the reciprocating motion of the carriage to the rotational motion of the sangya is characterized by meshing with a gear fixed to the printer or coaxially fixed to the phone rack and the sangya. A ribbon feeding mechanism according to claim (1) of the utility model registration.

(3) 1 The means for transmitting the reciprocating motion of the carriage to the rotational motion of the sangya includes a lipon mouthpiece whose both ends are fixed to the printer with an appropriate tension, which is fixed coaxially and integrally with the sangya. 3. The ribbon feeding mechanism according to claim (1) of the utility model registration, characterized in that the ribbon is wound around a pulley. ′
