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. When the card loading port is empty, the sensors send another signal, again reversing the roller direction (clockwise) and raising the elevator, thus reloading the cards into the loading port.
