ABSTRACT:
An operation device for an endoscope is provided including a casing having a through hole and a rotation shaft extending externally from the through hole. The device further includes a first operation unit having a base section located outside the casing such that it is rotatably mounted on the rotation shaft, and an extension section having a finger-operated member at an outer end portion, and a second operation unit having a base section located outside the first operation unit such that it is rotatably mounted on the rotation shaft, and an extension section extending radially from the base section and having an intermediate portion bending toward the casing and a button attached to an outer end. The rotation path of the button is created over the same plane as that of the finger-operated member and spaced apart from that of the finger-operated member at a predetermined angle. A bending operation unit is situated outside the second operation unit and rotatably mounted on the rotation shaft so that a bending tube section of the endoscope may be bent. The operation unit can be readily operated with the same fingers which have gripped the operation body. This assures an improved operability.
