    Abstract: An endoscope operation mechanism includes: a dial operating an endoscope function; a detection sensor that has a sensor rotation shaft to which rotation of a dial rotation shaft of the dial is transmitted and detects the rotation amount, and that outputs an electrical signal in accordance with the detected rotation amount to a control portion performing driving control of a driving source of the endoscope function; an initial position reversion mechanism applying a rotational force to the dial rotation shaft in an opposite direction to the direction in which the dial rotation shaft is rotated, to thereby cause the rotational position of the dial to return to an initial position; and a switching mechanism switchable between a first state in which a rotational force from the initial position reversion mechanism is applied to the dial rotation shaft, and a second state in which the rotational force is not applied.

    Abstract: An insertion device sets engage range which it prescribed in return power to the neutral position by elastic force of the spring and rotation resistance force by the slide power by elastic member for dial portion performing curving operation of a curving portion. If a rotary angle is beyond an engage range, the dial part lets a rotary point of view to order return in an engage range and, if there is a rotary angle in an engage range, the dial part keeps a target part in an observation field of vision.
