Power supply control apparatus and power supply control method

摘要

A power supply control apparatus for reducing the frequency of running a specific process in an electronic device when the device power turns on or off too soon after being turned off by monitoring the operating state of the power switch. When the power supply control apparatus detects an operation turning the power to the hybrid processing apparatus 1 off, the power supply control apparatus continues supplying power for as long as needed to complete a given shutdown process. However, if the power supply control apparatus 50 detects an operation turning the device power on again after the power supply stops but before reaching a predetermined reset voltage a reset and restart command is applied to the electronic device. More particularly, if an operation turning the power on again is detected during the period while the power supply is maintained to complete the shutdown process after the operation turning the power off is detected, the command restarts the electronic device without running a process normally run after start up such as a cleaning process in a printer.
