groove. Correction 1984. 3.11 The scope of claims for utility model registration is amended as follows. O Utility Model Registration Claims (1) An insertion device in which an objective lens is fixed to the tip member, and an image transmission means on the rear end side of the objective lens and an illumination means for emitting illumination light from the end surface are housed adjacently. In the endoscope, a filter member can be attached and detached in front of the objective lens, and a transparent member can be attached and detached in front of the end face of the illumination means, through a frame member on the distal end side of the insertion section. What is claimed is: 1. An endoscope characterized by being provided with a mounting means. (2) The filter member and the transparent member are formed in the shape of a disk divided into two so as to respectively cover the observation window and the illumination window in the tip member, as described in claim 1 of the utility model registration claim. endoscope. (3) The filter member is a neutral density filter that reduces the amount of transmitted light, or a filter that only passes light of a specific wavelength;
Alternatively, the endoscope according to claim 1, which is a utility model, is characterized in that the filter has a low transmittance at a specific wavelength. (4) The mounting means is characterized in that the filter member and the transparent member can be fixed by forming a screw in the frame member that is screwed into the threaded portion formed on the outer periphery of the tip member. The endoscope according to scope 1. (5) The mounting means is capable of fixing the filter member and the transparent member by press-fitting the outer periphery of the tip member into the inner peripheral surface of the frame member, as set forth in claim 1 of the utility model registration claim. Endoscope. (6) The endoscope according to claim 1, wherein the frame member is fixed so as to be covered with a plate-shaped protective member on the side facing the outside of the filter member and the transparent member. (7) The frame member is characterized in that a reflective member and a light guide are disposed facing each other in front of where the filter member and the transparent member are disposed, respectively. The endoscope described. (8) The frame member is characterized in that it is provided with a means for attaching and detaching the protective member, such as by providing a groove into which a plate-shaped protective member that covers the end face facing the outside of the reflecting member and the light guide is inserted.
