Abstract
A tip attachment provided with a mount fittable to a mount receptacle in the tip part of an endoscope is made to appear within the visual field of an observing optical system provided in the tip part before the tip attachment comes to separate from a predetermined fitted state so that the tip attachment may be prevented in advance from dropping.
