Abstract
A flexible, tubular extension guide has its one open end fixed to a control section housing constituting a grip or operation section of an endoscope and its external free end connected to an eyepiece section of an observation system. The guide can be bent in any direction such that the eyepiece section can be set in any desired position, and self-retained at that bent position. The base end portion of an optical fiber bundle of an observation system is introduced into the guide and the base end of the bundle is directly optically connected to the eyepiece section.
