PURPOSE:To improve the return rate of a portable storage medium by resetting an electrical connection to the portable storage medium and sending and receiving information again, at the time of sending and receiving the information to and from the portable storage medium are not executed normally. CONSTITUTION:An IC card inserted into a card insertion port 6 is carried by the rotation of a driving roller 33, and stopped at a position opposed to a connecting rear part 200 for executing an electrical connection. As a result, a solenoid 60a operates, a probe 61a contacts the contact 62a of the IC card, when the communication is not executed normally, it is considered that it is caused by the deficiency of an insertion of the IC card, the deficiency of the electrical connection to the IC card, etc. In such case, the communication processing is repeated by executing a position adjustment for forming back and forth a little the inserted IC card along a carrying path 32. When a normal communication cannot be executed even if the position adjustment is executed N times, the IC card is discharged.
