  • Publication number: 20180218180
    Abstract: An attaching structure of a card processing unit may include the card processing unit and an attaching frame. The attaching frame includes a frame side restriction part that restricts a movement of the card processing unit in a conveying direction, a thickness direction and a width direction of a card, and the card processing unit includes a processing unit side restriction part structured to engage with the frame side restriction part. For example, the frame side restriction part includes an engaging part structured to engage with a part of the processing unit side restriction part to restrict the movement of the card processing unit. The engaging part is an elastic piece capable of being elastically deformed from a restricting position where the movement of the card processing unit is restricted to a release position and the engaging part is engaged with the processing unit side restriction part by snap fitting.

  • Patent number: 9751707
    Abstract: The purpose of the present invention is to provide a card conveying mechanism capable of conveying a card in a horizontal direction and allowing for less space in a higher-level apparatus to be taken up even if the card conveying mechanism is capable of making the card parallel to the horizontal direction or tilting the card relative to the horizontal direction. The card conveying mechanism is provided with a card holder that has a draw and feed mechanism for drawing and feeding a card and temporarily holds the card therein, a draw and feed driving mechanism for driving the draw and feed mechanism, a carriage where the card holder is mounted, a carriage driving mechanism for moving the carriage linearly in a horizontal direction perpendicular to a direction in which the card is drawn into the card holder and a rotating mechanism for rotating the card holder with respect to the carriage around an axis in which the carriage moves.
