A data write apparatus includes a card conveyor path, a recording head, a sensor circuit, a Central Processing Unit (CPU), a drive circuit, and an enable section. A magnetic card is conveyed in the card conveyor path. The recording head is arranged on the card conveyor path and performs a recording operation on the magnetic card by energizing a winding coil. The sensor circuit is arranged on the card conveyor path near the recording head and detects the magnetic card conveyed in the card convey or path to output a detection signal. The CPU outputs write data to be written on the magnetic card in response to the detection signal from the sensor circuit. The drive circuit energizes the winding coil of the recording head on the basis of the write data from the CPU to perform the recording operation. The enable section enables the drive circuit for a predetermined time after the write data is output from the CPU to limit energization of the winding coil of the magnetic head to a time equal to or less than the predetermined time.

Apparatus for writing data on a magnetic card and preventing heat damage

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.

Card loading device

A card convey device includes a first convey path, a second convey path, a third convey path, jam detector, convey controller, and card sorter. The first convey path conveys a loaded card. The second convey path is branched from the first convey path and conveys a non-defective card distributed from cards conveyed from the first convey path. The third convey path is branched from the first convey path and conveys a defective card distributed from the cards conveyed from the first convey path. The jam detector detects jam of a card occurring in each of the first, second, and third convey paths. The convey controller conveys a card through each of the first, second, and third convey paths at a predetermined speed, stops a convey operation of the card when the jam detector detects jam of the card, and reconveys the card in response to a reconvey command. The card sorter distributes the card conveyed from the first convey path to one of the first and second convey paths on the basis of non-defective/defective information of the card, and forcibly distributes a reconveyed card from the first convey path to the third convey path.
