Patent ID: 8210438

Claim:
A medium processing device for use with a card; in which the card is inserted through an insertion slot, then the card is transferred so as to reach a back end of a card path while at least a part of a tail end of the card is exposed from the insertion slot, and thereafter processing operation for information to/from the card is carried out in response to manual performance of pulling out the card; the medium processing device comprising: a contact structure that comes into contact with a terminal of an integrated circuit mounted on an IC card at a back end position of the card path; a detection means for detecting the card that has been inserted into the back end position where the terminal and the contact structure contact each other; a locking means for locking the card at the back end position; and a control means for controlling execution and cancellation of locking operation by the locking means; wherein the control means executes locking operation by the locking means as soon as the detection means detects insertion of the card that has been inserted into the back end position, and afterwards, in a state that the contact structure has come into contact with the card, an activation process in which the card is judged whether the card is an IC card or not is executed and, when the card is not activated in response to the activation process for the integrated circuit, the card is judged that the card is not an IC card and the locking operation by the locking means is canceled.
