ンクリボン巻取り機構。[Claim for Utility Model Registration] It is connected to the ribbon shaft on the unwinding side and rotates by pulling out the ink ribbon as the carriage moves for printing, and when the carriage returns to the printing start position, the driving force of the motor is applied. The unwinding side gear rotates to wind up the ink ribbon that has been fed out by the motor, and the winding side ribbon shaft is connected to the unwinding side gear that rotates to wind up the ink ribbon fed out by the motor. A fixed type thermal printer comprising: a take-up side gear that rotates to take up the ribbon; and a ribbon gear that transmits the rotational force of a ribbon clutch gear connected to a drive motor to the unwind side gear and the take-up side gear. In the ink ribbon winding mechanism, the ribbon gear is composed of an unwinding side ribbon gear and a winding side ribbon gear which are coaxially connected to each other so as to be able to rotate independently of each other by meshing with the unwinding side gear and the winding side gear, respectively. A fixed type ink ribbon winding mechanism for a thermal printer, characterized in that the unwinding side gear is released from the connection with the winding side gear when the carriage moves for printing.
