<P>PROBLEM TO BE SOLVED: To improve an energy-saving property and convenience by using plural types of mobile detection means at least having different operation specifications of consumption power from one in operation. <P>SOLUTION: As a first human detection sensor 28, a pyroelectric sensor is used, as a second human detection sensor 30, a gesture sensor capable of detecting an operation form of a user is used. The first human detection sensor 28 always supplies electric power regardless of a type of a mode, but the second human detection sensor 30 blocks to supply electric power in a sleep mode, so that consumption power is suppressed. At a time point when the first human detection sensor 28 detects a mobile body, electric power is supplied to the second human detection sensor 30 and an operation form is discriminated on the basis of a detection result by the second human detection sensor 30. This enables acquiring of information on a user (types of processing, etc.) with higher accuracy than that of the first human detection sensor 28, and realization of minimum requirement electric power consumption without losing convenience. <P>COPYRIGHT: (C)2013,JPO&INPIT |
