Abstract

PURPOSE:To prevent the read miss of amount information caused by the vibration of an equipment, etc., by inhibiting the reception of a magnetic card in the course of operation of the equipment. CONSTITUTION:When the insertion of a card 16 is completed, a sub- microcomputer 46 discriminates again whether a laundry machine is in the course of operation or not, and if it is in the course of operation, the card 16 is discharged immediately. The operating state of the laundry machine can be discriminated in accordance with whether a main microcomputer 3 is sending out a signal to a driving circuit 7 or not. Also, it can be discriminated by detecting the electric conduction state of a load of drainage solenoid valves 5, 6, etc., by a photocoupler. In such a manner, the read miss of amount information caused by the vibration of the equipment, etc., can be prevented.
