Abstract
An operating unit for an endoscope is provided in which focusing and/or zooming operations can be easily performed using a hand holding an operating unit, without removing a hand holding an insertion unit from the insertion unit. An optical system operating member for performing focusing and/or zooming operations on an observation optical system is disposed at a position where the optical system operating member is operable by the thumb of a hand holding an operating unit. The optical system operating member is arranged to be coaxially rotatable with a bending operation member disposed on a side face of the operating unit.
