PURPOSE:To reduce an area of an end diameter by placing an illuminating means such as a solid light emitting element coaxially to an objective lens system, on the outside circumference of the objective lens system placed on the tip of a tip constituting part of an endoscope inserting part. CONSTITUTION:A lens supporting frame 15 is provided in the axial direction of a tip constituting part of an endoscope inserting part 1 formed in the shape of a pipe, and an objective lens system 5 is incorporated. Solid light emitting elements 2, 3 and 4 for R, G and B are placed coaxially at an interval of about 120 deg. in a ring-shaped flange part of the tip surface of the lens supporting frame 15, and a solid image pickup element 6 is provided in the rear of the objective lens system 5, photodetects an optical image formed by the objective lens system, converts it to an electric signal and outputs it. In this way, this device is constituted so as to execute a color display basing on this electric signal. |
