From the detection result of a sensor for detecting a card (4), whether or not the card (4) exists in the inside (22), and whether or not the card (4) exists in a return area (23) are determined, respectively, and in the state where it is determined that the card (4) exists in the inside (22), if the time counted by a first timer (7) has reached a time while a command from a host system (1) is not received by a communication unit (17), then it carries out the communication error process of addressing that the command is not received. That is, the card (4) in the inside (22) is returned to the area (23), and subsequently, in the state that it is determined that the returned card (4) exists in the area (23), if the time counted by a second timer (8) reaches a second time while the card (4) is not taken out from the area (23), the card (4) is taken to the inside (22). |
