DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] 1. Field of the Invention [0002] The present invention relates to a power-off control device for controlling power-off of electronic equipment.

[0002]

2. Description of the Related Art Today, personal computers, printers, fax machines, and many other devices connected to an AC power supply are overflowing in offices and homes. Furthermore, these are kept connected to the AC power supply even in an environment where they are not used, and the display such as a clock of each device,
Not a little power is wasted due to the standby operation for shortening the start-up time.

[0003] Further, in a device using an AC adapter, there is a situation where power is wasted on the AC adapter side even if the main power switch on the device side is turned off. Under such circumstances, laws and regulations on energy saving are being strengthened in order to improve the global environment such as solving global warming.

[0004]

However, at present, energy saving fundamental activities depend on human work such as disconnecting an AC outlet. A
Regarding the C power supply, the condition in use such as that related to safety, such as Japanese Utility Model Application No. 6-8538, “Home power supply monitoring system”, and Japanese Patent Application No. 10-219434, “Printer power supply monitoring device”. Although there was a feature of performing monitoring, there was no solution to the problem of safely turning off the AC power supply of the device.

For example, if only the AC power supply is turned off, there are already commonly used breakers and outlets with SW. However, if the AC power supply is turned off by the breaker, the system may be destroyed especially in a computer. In addition to the high performance, there is a problem that the power is also turned off during the operation of the OA equipment.
