PROBLEM TO BE SOLVED: To precisely transmit information on the reason for automatic turn-off to a user by providing a notice control means for presenting trouble information from a trouble information storage means when a main switch put in the off- state is turned on by the user. SOLUTION: A power supply control part comprises a CPU 3031 taken as the center, decoders 3032-3034, extended I/O 3035-3041, a ROM 3242 and a RAM 3043. The CPU 3031 is connected to the ROM 3242 and the RAM 3043 to monitor a trouble detecting sensor through decoders 3032-3041. When any trouble occurs, a trouble occurrence generating signal transmitted from a specified detecting sensor is taken in, and a trouble code corresponding to the trouble occurrence signal is retrieved from the ROM 3242 to be stored in the RAM 3043. The CPU 3031 displays the stored trouble code on a liquid crystal display part after a main switch operation key and a trouble state release key are simultaneously turned on by the user. |
