    摘要: An ink ribbon cartridge may include a supply roll; a winding roll; and a power transmission mechanism to transmit power from a drive source to the supply roll and the winding roll. A direction in which an ink ribbon is wound by the winding roll is a ribbon winding direction and a direction in which the ink ribbon is wound by the supply roll is a ribbon rewinding direction. The power transmission mechanism may include a winding side one-way clutch to transmit a driving force in the ribbon winding direction to the winding roll and cut off transmission of the driving force in the ribbon rewinding direction to the winding roll; and a supply side one-way clutch to transmit the driving force in the ribbon rewinding direction to the supply roll and cuts off transmission of the driving force in the ribbon winding direction to the supply roll.
