Abstract

PROBLEM TO BE SOLVED: To make maloperation of power source switch surely preventible by making a device to have such constitution that a power source is shifted to an off-state after it is confirmed whether the power source switch can be turned off or not, when the power source switch is turned off at the time of a power saving mode. SOLUTION: When such instruction is given at the time of a power saving mode that a power source switch 44 is turned to an off-state from an on-state, a central processing unit 40 returns a mode of a data processing device from the power saving mode to normal mode conforming to a program stored in a ROM 41 without turning off the power source switch 44 instantly by a power source switch control circuit 43. And, the device 40 displays a message confirming whether the power source switch 44 may be turned off or not on a screen display device 46 through an outer I/F circuit 45. Then, when message that a power source may be turned off is inputted from an input device 47, first, the central processing unit 40 turns off the power source section 44 through a power source switch control circuit 43.
(57)【要約】 【課題】 省電力モード中によるユーザの電源オン指示 が電源オフ指示となっていることを明示して、電源スイ ッチの誤操作を確実に防止することである。 【解決手段】 省電力モード時に電源スイッチ44によ りOFF指示した場合、本当に電源スイッチをOFFし てよいかどうかを画面表示装置46に表示し、該画面表 示装置46でオフ指示されたことを確認して、電源スイ ッチ制御回路43が電源をオフ状態に遷移させる構成を 特徴とする。
