INFORMATION PROCESSING DEVICE AND UNAUTHORIZED PROCESSING DETECTION METHOD

To further strengthen a function for preventing illegal alteration due to an illegal opening of a housing.SOLUTION: An information processing device detects whether a housing is in an open state or a closed state, and includes: switch means having a reflection surface on the outer surface; light emitting means arranged to emit light of an arbitrary wavelength toward a reflection surface of the switch in a closed state of the housing; light receiving means arranged to receive the light emitted from the light emitting means via the reflecting surface of the switch in the closed state of the housing; and control means for detecting an abnormality around a switch on the basis of the amount of light received by the light receiving means.SELECTED DRAWING: Figure 1 【課題】筐体の不正開放にかかる不正改造抑止用機能をより強固にする。【解決手段】情報処理装置は、筐体の開状態と閉状態の何れの状態であるか検出するとともに、外面に反射面を有するスイッチ手段と、筐体の閉状態において、任意の波長の光をスイッチの反射面に向けて送出するように配置された発光手段と、筐体の閉状態において、スイッチの反射面を介して発光手段から送出された光を受光するように配置された受光手段と、受光手段の受光量に基づいてスイッチ周囲の異常を検出する制御手段と、を有する。【選択図】図１
