  • Patent number: 5433583
    Abstract: A card loading device includes an elevator, a roller, a card loading port, and two sensors for detecting the feeding of cards, exhausting the feeding of cards and the reloading of cards. The elevator raises/lowers a plurality of accumulated cards. The roller is arranged at a card feed position and rotated clockwise to feed a card located at an uppermost position of the accumulated cards and brought into contact with the roller when the elevator is raised. The card loading port has an opening slightly larger than a thickness of a card and loads a card fed by the roller. The two sensors can detect the proper and the improper loading of a fed card at the card loading port. When a card has been improperly loaded, the sensors send a signal that reverses the roller direction (counterclockwise) and lowers the elevator, thereby exhausting the card from the card loading port.

  • Patent number: 5424522
    Abstract: A card convey device includes a card convey unit, a punching unit, a counting unit, and a control unit. The card convey unit selectively conveys a card in a discharging direction and an opposite direction thereto. The punching unit punches the card which slows down, while the card is conveyed by the card convey unit in the discharging direction. The counting unit is enabled after a punching operation is performed by the punching unit, and counts the number of times of repetition of a reciprocal card convey operation in the opposite direction and the discharging direction. The control unit controls a convey operation of the card convey unit and repeatedly reciprocally conveys the card in the opposite direction and the discharging direction until the count value of the enabled counting unit reaches a predetermined count value. When the count value of the counting unit reaches the predetermined count value, the control unit conveys the card in the discharging direction and discharges the card.
