Abstract

<P>PROBLEM TO BE SOLVED: To effectively defog the lens surface of a rigidscope. <P>SOLUTION: A light guide 12 for illumination is inserted into a rigid scope inserting part, and a light guide 13 for heating is inserted threreinto independently of the light guide 12. The light guide 12 guides an illumination light to the tip of the rigidscope, and the light guide 13 guides the light for defogging to the tip of the rigidscope. Each of the lights can be independently controlled. In the control of the illumination light, since the amount of the light for the defogging is prevented from being changed, the lens surface can be appropriately heated so that the occurrence of fogging on the lens surface can be effectively prevented. <P>COPYRIGHT: (C)2004,JPO
