ABSTRACT:
Disclosed is a read/write apparatus for magnetic card, which includes a card conveyance passage along which a flexible magnetic card is guided. The passage has a direction changing portion where the direction of the passage is gradually changed, and a downstream portion where the passage extends vertically of the apparatus. By virtue of this arrangement the apparatus can be small in depth size and have a thin body.
When an additional insertion button of the apparatus is depressed by a customer, zero value is written on the magnetic card and the card is returned. Upon insertion of an additional card, the sum of the balance of the additional card and the previous card is transmitted to an external information processing unit installed in a vending machine, to permit a single sales operation within the sum of the balances.
