Electric apparatus capable of turning off a power supply circuit automatically to inhibit resuming of operation until safety is ensured at the time of restoration from abnormal stop
 In the electric apparatus of the present invention, when the supply of electric power to a primary power supply circuit is started, a check is made to see if the apparatus has been turned ON by operation of a switch device S, by collation with the contents stored in a memory (not shown), and in accordance with the result of the collation a control system circuit makes control to continue or interrupt the supply of electric power to the primary power supply circuit. Therefore, in the case of a rise from an abnormal condition such as power failure, the supply of electric power to the primary power supply circuit can be interrupted rapidly. Thus, whether a trouble has occurred or not during power failure can be checked before resuming the operation and the occurrence of a danger can be prevented thereby.
