。[Claims for Utility Model Registration] A cam is rotated in accordance with the transmitted driving force from a driving force transmission switching mechanism that switches the transmission destination of the driving force from the motor according to the rotational direction of the motor, and the cam is rotated in accordance with the displacement of the cam. A head up-down mechanism is mounted on a carriage that moves the thermal head in the printing direction. In the carriage mechanism of a printer that performs printing, the carriage mechanism is provided between the cam of the head up-down mechanism and the driving force transmission switching mechanism, and is configured to transmit the driving force of the rotational force generated by the predetermined pressure to the cam. A printer carriage mechanism comprising rotational force damping means for damping transmission to a switching mechanism.
