Abstract
A pipe-like extension guide is inserted into a control section housing (operation section) through an insertion hole in the side wall of the control section housing connected to the base end of an elongated sheath. An elongated cut out is formed in the side wall of the inserted end portion of the extension guide, and the base end portion of an optical fiber bundle for observation is introduced through the cutout into the extension guide such that the end face of the bundle aligns with an eyepiece held in an eyepiece section which is fitted over the guide. The end surface of the extension guide is intimately abutted against the inner wall of the housing.
