PROBLEM TO BE SOLVED: To provide a device constitution, in which power consumption can be further reduced when a device is moved into a power saving mode or the like by switching a power supply system according to the operating state of the device, with respect to a device equipped with plural power supply circuits. SOLUTION: When the moving condition to a power saving mode of a system is fulfilled, the low-speed of the operating speed of a CPU 13 is obtained, and a mode signal MS supplied from the CPU 13 is inverted so that the operation of an A power source circuit 11 can be stopped by a power source control circuit 20. Also, the power control circuit 20 transmits a control signal to a power supply interrup switch circuit 21, so that an A output line La can be conducted with a B output line Lb. |
