<p>PURPOSE:To correctly supply a power source to a device to be operated after a delay and to cause the action of a system to be smooth by confirming that the supply of an ac power is started and executing a control to cause a power unit to start the supply of a dc power to a main body device after a delay for a prescribed time from the supply starting time. CONSTITUTION:A power unit 2 of a power source control device having a delaying timer senses the supply start of the ac power, and a COM signal is inputted to a power source control unit 1 having a delaying timer. After a timer 3 is activated by the input and the set and prescribed time passes, a switch 4 is operated, the output of a Power Off signal 7 is stopped, and simultaneously, a Power On signal 8 is outputted. A power source output control circuit 5 of the power unit 2 to receive the signals 7 and 8 starts the supply of the dc power to the main body device. After the delay of a specific time from the time when the supply of the ac power is started, the supply of the dc power to the main body is made possible to be started.</p> |
