Patent ID: 7788507

Claim:
A control apparatus, comprising: an oscillating device which oscillates a clock signal of predetermined frequency by supplied power; an input device which has at least a port into which a specific signal is supplied; a switching device that switches ON and OFF supply of the power to said oscillating device; and a control device which at least controls ON and OFF power supply of an electronic device based on said clock signal oscillated by said oscillating device when said switching device is in ON status; wherein said switching device switches ON supply of the power to said oscillating device, if said specific signal is supplied into said port when supply of the power to said oscillating device is in OFF status; wherein the control apparatus further has an instruction device which, after receiving input operation by the user and supplying a first control signal associated with a content of said operation into said port, supplies to said input device a second control signal that is identical to said first control signal, wherein said control device has at least: a discriminating device which discriminates the content of operation associated with said second control signal based on said clock signal oscillated from said oscillating device when said switching device is switched to ON; a determining device which determines whether the content of operation discriminated by said discriminating device matches predetermined content or not; and a power supply control device which turns ON the power of said electronic device, when it is judged that said content of operation matches the predetermined content by said determining device.
