Abstract
This endoscope apparatus is provided with an elongate flexible insertable part; a winding unit with a supporting structure having a winding member connected with the insertable part at the base end for winding up and housing the insertable part; an illuminating device for emitting an illuminating light for the endoscope; and an observing device for producing an image of an object to be observed. An external apparatus forming one or both of the illuminating device and observing device is provided separately from the winding member. A flexible connecting means is extended axially out of the side of the winding member and operatively connects the insertable part to the external apparatus.
