Endoscope containing solid-state image pickup element

Abstract

Abstract PURPOSE:To observe the whole periphery, and also to execute easily the operation without requiring an image rotator and also the correction of azimuth by structuring an image pickup means so that it can be driven to rotate without interposing a mirror or a prism. CONSTITUTION:As for an endoscope 1, a hard tip part 3 is formed on the tip of a flexible inserting part 2, the almost whole area of the tip side is covered with a transparent cover 4, the rear end part of the opening side is fixed to the outside periphery of a tip part body 3A, and a rotary tip part 3B which becomes freely rotatable is formed on the inside of the cover 4. To the front part (top part) of the inside of the cover 4, the stator side of a rotation driving motor is fixed with a screw, etc., its revolving shaft 6A is fitted and contained, etc. into the recessed part of the rotary tip part 3B, and the rotary tip part 3B is driven to rotate together with a rotation of the revolving shaft 6A. A recessed part is formed in the direction orthogonal to the revolving shaft 6A of the motor 6 and an objective lens system 8 fixed to a cylindrical lens frame 7 is contained, and a solid-state image pickup element 9 is provided on its image forming position and an image pickup means for executing the image pickup of image of an object in front of the optical axis (namely, the side opposed directly to the revolving shaft 6A) of the objective lens system 8 is contained.
