To suppress the occurrence of an image noise by suppressing an influence, on an imaging signal, of a signal indicating that an input reception part receives an operation input, when the signal is transmitted.SOLUTION: An endoscope according to an embodiment comprises: a cable for transmission of an imaging signal; an input reception unit; a cable for transmission of an operated signal; and a timing control unit. The input reception unit is provided on the same side as an image pickup device with respect to the cable for transmission of an imaging signal and when receiving an operation input, outputs an input signal. The cable for transmission of an operated signal transmits an operated signal indicating that the input reception unit has received the operation input, and forms a composite cable obtained by integration with the cable for transmission of an imaging signal. The timing control unit is provided on the same side of the image pickup device with respect to the cable for transmission of an imaging signal and receives a synchronization signal and the input signal, the timing control unit outputting the operated signal in response to timing of the reception of the synchronization signal, as a result of the reception of the input signal.SELECTED DRAWING: Figure 2 【課題】入力受け部が操作入力を受けたことを示す信号が伝送される際に、当該信号から撮像信号が受ける影響を抑え、画像ノイズが発生することを抑える。【解決手段】実施形態の内視鏡は、撮像信号伝送用ケーブルと、入力受け部と、被操作信号伝送用ケーブルと、タイミング制御部とを備える。入力受け部は、撮像信号伝送用ケーブルに対して撮像素子と同じ側に設けられ、操作入力を受けることにより被入力信号を出力する。被操作信号伝送用ケーブルは、入力受け部が操作入力を受けたことを示す被操作信号を伝送し、撮像信号伝送用ケーブルと一体化された複合ケーブルをなす。タイミング制御部は、撮像信号伝送用ケーブルに対して撮像素子と同じ側に設けられ、同期信号及び被入力信号が入力し、被入力信号が入力することにより、同期信号が入力するタイミングに応じて被操作信号を出力する。【選択図】図２
