<p>PURPOSE:To realize power saving by suppressing power consumption in standby time to a necessary minimum by setting a mode at a sleeping mode in a standby state, and prohibiting a function other than that of a data reception part. CONSTITUTION:This system is equipped with a device 1 having a microprocessor 3 provided with the sleeping mode and the data reception part 4, and an external device 2 connected to the data reception part 4 and transmits a signal to start an operation to the device 1. The sleeping mode of the microprocessor 3 can be cancelled by a signal to cancel the sleeping mode from the external device 2 received by the data reception part 4. Also, the microprocessor 3 can rush into the sleeping mode by the completion of processing or a cancel signal from the external device received by the data reception part 4. Thereby, it is possible to suppress the power consumption in the standby time to a required minimum.</p> |
