Abstract
A card read/write device of the type comprising an inlet sensor disposed at a card insertion inlet, a shutter which opens in response to the detection signal from the inlet sensor, a transportation mechanism driving sensor disposed backwardly of the shutter, a card transportation mechanism disposed backwardly of the second-mentioned sensor for transporting the inserted card backwardly and a card information read/write means disposed within the card transportation mechanism, characterized in that when the trailing end of the card passes past the transportation mechanism sensor in the case of returning the card, the card transporting mechanism is deactivated and when the transportation mechanism driving sensor is turned on again under these conditions, the card transportation mechanism is activated again to transport the card backwardly so that the read/write operation of the card is accomplished.
