Abstract:
The purpose of the present invention is to reduce the influence on video signal transmission by a solid-state image capture element or on a signal line for transmitting drive power to a sensor or a tip-end light source or the like due to bending of a flexible tube. The present disclosure provides an endoscope comprising: a connector portion connected to a controller equipped with a power supply; an operating portion connected to the connector portion; and an insertion portion to be inserted into an area to be examined. The connector portion is provided, on the operating portion side thereof, with a bending-prevention portion and a flexion portion successively from the connector portion. The endoscope has a rotating mechanism for enabling rotation of the bending-prevention portion and the flexion portion. A first substrate disposed in the connector portion has a first wireless feeding device for transmitting power from the power supply. A second substrate disposed in the flexion portion has a second wireless feeding device for receiving power transmitted wirelessly from the first wireless feeding device.
