Claims

[Scope of utility model registration request]

a type ring rotatably fitted onto the drive shaft and having a plurality of type letters formed at predetermined intervals in the circumferential direction on the outer periphery; A gear shaft having a plurality of notches formed at predetermined intervals in the circumferential direction, a lock pawl that can be selectively engaged with and detached from the notches of the gear shaft, and between the type ring and the gear shaft. The gear shaft is rotatably supported, and one end is inserted into a retaining hole provided in the gear shaft, and the other end has a ratchet pawl that can be freely engaged and detached from a notch formed on the outer periphery of the drive shaft. The rotating shaft is provided on a tangent to the drive shaft, and the notch of the drive shaft has one side surface of the other end of the ratchet pawl that can be supported without any force acting in the radial direction of the drive shaft. The other end of the ratchet claw fits into the notch of the drive shaft during the type selection cycle, and the locking claw engages with the gear shaft when moving from the type selection cycle to the printing cycle. One end of the ratchet pawl is pressed against one side wall of the engagement hole by fitting into a predetermined notch of the gear shaft and applying a pressing force to the gear shaft in a direction opposite to the rotational direction of the drive shaft. A printer characterized in that the ratchet pawl is rotated to separate from the notch of the drive shaft.
