PROBLEM TO BE SOLVED: To provide a device with a lock which has good operability and can enhance accuracy of determination by effectively shutting off disturbance light.SOLUTION: A device with a lock includes a biometric authentication device 2 in which a palm or a finger is used as a body part 1 to be authenticated and an authentication-operation-use recess 4 which is formed in a device casing 3 and which is open in the front of the device casing 3. The device with the lock operates the lock when the biometric authentication device 2 succeeds in authentication to the body part 1 to be authenticated, which is positioned by a read guide 6 disposed in a bottom wall 5 of the authentication-operation-use recess 4. In addition, a ceiling of the authentication-operation-use recess 4 is provided, in a protruding manner, with a transparent filter cover 7 having a filter function to cut off a wavelength component of radiation light to the body part 1 to be authenticated by the biometric authentication device 2.COPYRIGHT: (C)2011,JPO&INPIT【課題】操作性が良好で、かつ、外乱光を効果的に遮断して判定精度も高めることのできる錠付き装置の提供を目的とする。【解決手段】手の平、または手指を被認証部位1とする生体認証装置2と、装置筐体3に形成され、該装置筐体3の正面に開放される認証操作用凹部4とを有し、認証操作用凹部4の底壁部5に配置される読み取りガイド部6により位置決めされた被認証部位1に対する生体認証装置2による認証成立を条件に錠操作が行われる錠付き装置であって、前記認証操作用凹部4の天井部には、生体認証装置2による被認証部位1への照射光の波長成分をカットするフィルタ機能を有する透明なフィルタカバー7が突設される錠付き装置【選択図】 図3
