<p>PURPOSE:To exactly write a data, even if an AC voltage is cut off and a reset signals is sent out by constituting the titled device so that a central processor sends out an inhibit signal in a period in which the possibility of a malfunction is high, at the time of inputting a reset signal of data write, etc. CONSTITUTION:When a central processor 10 is executing an operation in which the possibility of a malfunction is high, by inputting a reset signal of data write, etc., this central processor 10 sends out an inhibit signal H in this period. In such a state, when a DC voltage output level of a power source stabilizing circuit 2 drops, a reset signal B is sent out of this power source stabilizing circuit 2, this reset signal B is sent to a gate circuit 11 for converting the inhibit signal H to a gate signal, and thus, when the inhibit signal comes not to exist, the reset signal is sent to the central processor 10 and the central processor 10 is reset. In such a way, even if an AC voltage is cut off and the reset signal is sent out, a data can be written exactly.</p> |
