2. Description of the Related Art Electronic and electrical equipment operates by receiving power from a power supply built therein or from an external power supply. Generally, the supply and cutoff of the electric power depend on human judgment. There is a switch for turning on / off the power supply between the power supply and the operation circuit of the electronic / electric device. Such manual switches, where it is important not to work carelessly, are operated by reasonably strong human power. It is a principle of the machine that the operation and stoppage of the electrically driven machine is performed artificially.

[0003] A technique for non-artificially enabling a computer to operate at a set time is realized by using a real-time clock built in the computer. In most cases, the setting of the automatic operation start time depends on the OS and the BIOS.

This is possible only when the power of the computer is already turned on.

If the operation of the machine needs to be stopped automatically when the environment deteriorates, the principle of the machine is not applied exceptionally. In order to automatically turn on the power of a computer automatically turned off after a certain period of time when the environment deteriorates, a technology that provides a timer on the computer side
This is known from JP-A-4-247508. This technology is an automatic power control technology that automatically responds to physical phenomena, and is not an artificial control technology.

[0005] A power supply control technique for operating an electronic device such as a computer at a desired time without relying on artificial judgment, not by human power, and without being restricted by a spatial position, has been proposed.
Not known at all. It is required that the initial conditions of the operation of the electronic device be given unconditionally in terms of time and space.

[0006]

SUMMARY OF THE INVENTION An object of the present invention is to provide a power supply controller, a power supply control system, and a power supply controller capable of giving an initial condition of operation of an electronic device in a time and space free manner.
It is to provide a power control method.
