Abstract

PURPOSE:To branch a function to continuous starting or initial starting, by providing the titled device with a timer clocking time at the disconnection of an electric power for the whole system and connecting a means outputting an initializing signal individually at the connection of the electric power source to each control part. CONSTITUTION:A power-off time timer 6 in a power-off timer unit 2 detects electric power supply from an electric power unit 1, i.e. power-off of a system electric power source, discriminates whether the power-off is long or short and outputs the detecting signal to a signal line 11. An initializing signal which is turned off for a fixed period when electric power is supplied to a microprocessor 7 in a control unit 3 and the microporcessor 7 is started is outputted from the microprocessor 7 to a signal line 12 through a driver circuit 8. In said constitution, restarting of the system after the restoration of the electric power source from power-off or disconnection is divided into continuous starting continuing operation under a condition at the power-off and initial starting from an initial value.
