Abstract
An endoscope comprises an insertion portion, an operation portion body provided at a proximal end side of the insertion portion, a knob provided in the operation portion body, the knob configured to rotate around a rotation shaft, and a turn locking mechanism provided in the knob. The turn locking mechanism includes a lock button reversibly translatable from a first position to a second position, a lock bar connected to the lock button, the lock bar extending from an inside surface of the lock button, and a fixed member attached to the operation portion body. When the lock button is in the second position, the lock bar engages the fixed member to prevent the knob from rotating around the rotation shaft.

An operation portion for use with an endoscope, comprising:
- a knob configured to rotate around a rotation shaft;
- a lock button provided at the knob, the lock button configured to translate between a first position and a second position;
- a first lock bar extending from an inside surface of the lock button;
- a second lock bar extending from the inside surface of the lock button;
- and
- a fixed wall provided in the knob,
- wherein the first lock bar is separated from the second lock bar with the rotation shaft interposed therebetween,
- wherein, when the lock button is in the second position, at least one of the first lock bar and the second lock bar penetrates completely through the fixed wall to prevent the knob from rotating around the rotation shaft, and
- wherein, in a view along the rotation shaft, the lock button is located on an opposite side of the rotation shaft from the fixed wall.
