PROBLEM TO BE SOLVED: To provide an endoscope device whose grip part is provided at a base end of an insertion part to be inserted into the inside of a body cavity and includes a loading part for a battery and an operation switch for operating ON/OFF of an endoscope electric drive part in the grip part, and which includes a reasonably configured lock mechanism for a battery lid and/or a detachable connector on the base end of the insertion part to improve safety and simplicity.SOLUTION: There is configured a lock mechanism including: a lock function for inhibiting a battery lid 22 of a battery loading part 21 provided in a grip part main body 20 from being opened, by an operation switch 40, lid lock member 50, lock hole 22a, engaging projection 11a, and the like and/or a lock function for inhibiting a detachable connector 11 of the insertion part from being disconnected. The lock mechanisms lock operation is performed by operation of the operation switch 40 for operating ON/OFF of an endoscope electric drive part. The lock mechanism is made to be in the lock state at least when the endoscope electric drive part is in the ON state. Thereby, opening of the battery lid and disconnection of the detachable connector are inhibited when observing the inside of the body cavity.COPYRIGHT: (C)2015,JPO&INPIT【課題】体腔内に挿入される挿入部の基端に把持部が設けられ、電池の装填部及び内視鏡電気駆動部のON・OFFを操作する操作スイッチが把持部に設けられた内視鏡装置において、電池蓋及び/又は挿入部基端の着脱コネクタのロック機構を合理的に構成して、安全性及び簡素性を向上した装置を提供する。【解決手段】操作スイッチ40、蓋ロック部材50、ロック穴22a及び係合突起11a等により、把持部本体20に設けられた電池装填部21の電池蓋22の開放を阻止するロック機能、及び/又は挿入部の着脱コネクタ11の離脱を阻止するロック機能を有したロック機構が構成される。このロック機構は内視鏡電気駆動部のON・OFFを操作する操作スイッチ40の動作によりロック操作され、少なくとも内視鏡電気駆動部のON状態でロック状態とされる。これにより体腔内観察時に電池蓋の開放、着脱コネクタの離脱を阻止する。【選択図】図2
