PROBLEM TO BE SOLVED: To provide an insertion device in which an operation part is provided to the insertion part or an operation part is fitted to the insertion part, capable of appropriately recognizing a cause for an operation stoppage of the operation part.SOLUTION: An insertion device includes: a power control part for controlling a state of supplying power to a driving source based on input of an operation at an operation input part； and a driving force transmission unit for transmitting driving force to an operation part when an operation member is operated in a state of being connected to the operation part. The insertion device includes a state detection part for detecting at least one of a driving state of the driving source that changes according to a load on the driving source, and an operation state of the operation member that changes according to a load on the operation member and a transmission state of the driving force to the operation member, and a transmission control part for controlling an index sound transmission state based on the result of the detection by the state detection part.SELECTED DRAWING: Figure 2【課題】挿入部に動作部が設けられる、又は、挿入部に動作部が取付けられる挿入装置において、動作部の動作が停止する原因を適切に認識可能な挿入装置を提供すること。【解決手段】挿入装置は、操作入力部での操作の入力に基づいて、駆動源への電力の供給状態を制御する電力制御部と、動作部に接続された状態で作動部材が作動されることにより、駆動力を前記動作部に伝達する駆動力伝達ユニットと、を備える。前記挿入装置は、 前記駆動源への負荷に対応して変化する前記駆動源の駆動状態、及び、前記作動部材への負荷及び前記駆動力の前記作動部材への伝達状態に対応して変化する前記作動部材の作動状態の少なくとも一方を検出する状態検出部と、前記状態検出部での検出結果に基づいて、指標音の発信状態を制御する発信制御部と、を備える。【選択図】図２
