The card inverting unit may include a card holding part, a card drawing and feeding mechanism, and a rotating mechanism that rotates the card holding part. A conveyance path may be provided inside the card holding part. The conveyance path may be linear. The card drawing and feeding mechanism may include two drive rollers, and two pad rollers. A distance between a center of the drive roller and a center of the thermal head may be shorter than a length of the card. The thermal head may print on the card while the card conveyance mechanism conveys the card. The rotating mechanism may rotate the card holding part such that the conveyance path is inclined.
