Abstract

PURPOSE:To prevent malfunction when the operating condition is not well arranged yet, by furnishing a holding part which holds annex circuit, a lid, a lid switch, and a lever switch interlocking with a lever. CONSTITUTION:To insert an annex circuit in an electric appliance, first a lid 6 is opened to deactuate a lid switch 11, followed by insertion of the annex circuit into a holding part, and then a lever switch is turned on. The lid 6 is shut to cause the lid switch 11 to be turned on, and a control part 9 is formed that the annex circuit is connected. To take out this annex circuit, the lid 6 is opened to turn off the lid switch 11, and the control part 9 is informed that the annex circuit is going to be taken out. Taking-out of the annex circuit is done by moving the lever, and the lever switch is put in off state. Thereby a time lag is generated from opening of the lid 6 till an IC card 4 is set off, and in the meantime the control part 9 either interrupts or ends the information processing for the IC card 4, and thus the condition is accomplished in which control of the body 1 can be performed normally.
