<P>PROBLEM TO BE SOLVED: To provide a card processor performing judgment for oneself and taking measures when transmission from an upper device is cut off by some problem to suppress suffered damage to the minimum. <P>SOLUTION: From a detection result of a sensor detecting a card, it is decided whether a card is present in the inside or not, and it is decided whether the card is present in a return port or not. When a time counted by a first timer reaches a prescribed time T1 as a communication part does not receive a command from the upper device in a state that it is decided that the card is present in the inside, card return/retaking-in processing is executed as communication error processing for coping with the non-reception of the command. In the card return/retaking-in processing, the card present in the inside is returned to the return port under the reaching of the counted time of the first timer to the prescribed time T1, and thereafter, the card is taken in the inside when a time counted by a second timer reaches a prescribed time T2 as the card is not extracted from the return port in a state that it is decided that the returned card is present in the return port. <P>COPYRIGHT: (C)2007,JPO&INPIT |
