Abstract

PURPOSE:To prevent a control part and elements from being broken by static electricity by grounding the contactor of a contact block through a high resistance circuit when the contactor abuts the input/output terminal of a memory card for the 1st time, and connecting it to a control part a specific time later. CONSTITUTION:The contact piece of a switch 23 is fallen down on the side of a contact (b) and connected to the high resistance circuit 25 before the contactor 17a of the contact block contacts the terminal of the IC card. When the contactor 17a contacts the terminal of the IC card, the static electricity of the IC card is discharged through the switch 23 and high resistance circuit 25. The contact piece of the switch 23 is switched from the side of the contact (b) to the side of a contact (a) the specific time after the contactor 17a contacts the terminal of the IC card, and then the data on the IC card is read in a control part.
