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.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. 【課題】少なくも動作中の消費電力と動作仕様が異なる複数種類の移動体検出手段を用いて、省エネ性及び利便性の向上を両立させる。【解決手段】第１の人感センサ２８として焦電型センサを用い、第２の人感センサ３０として使用者の動作形態を検出可能なジェスチャーセンサを用い、第１の人感センサ２８はモードの種類に関わらず常時電力供給するが、第２の人感センサ３０はスリープモード時は電力の供給を遮断することで、消費電力を抑制している。また、第１の人感センサ２８で移動体を検出した時点で、第２の人感センサ３０に電力を供給し、第２の人感センサ３０による検出結果に基づいて動作形態を判別し、第１の人感センサ２８による検出精度よりも高い精度で、使用者に関する情報（処理の種類等）を得て、利便性を損なうことなく、かつ、必要最小限の電力消費を実現した。【選択図】図７
