<p>PROBLEM TO BE SOLVED: To eliminate wasteful power consumption in unnecessary circuits by subdividing a feeding system into circuit blocks, noticing the utilization of color information and feeding only to a circuit block that is needed for the information processing of an execution object. SOLUTION: When a SW5 of a trigger switch 18 is turned on, a feeding control signal VCT 1 is turned on, a feeding SW1 is turned on, power supply is fed to a feeding system VDD 1, and an FDD 14 and an SSG circuit 8 goes into an operation state. When a spindle motor of the FDD 14 is started and reaches a prescribed speed and a lock signal for motor control is outputted, a feeding control signal VCT 2 is turned on, a feeding SW2 is turned on, power supply is fed to a feeding system VDD 2 and an imager 9, a process circuit I 10, an AE circuit 15, an AF circuit 16, an AWB circuit 17 become respectively in an operation state. Thus, feeding stop, etc., to the FDD, etc., are performed at with reguing timing during a corresponding time accompanying the operation of the switch 18.</p> |
