PROBLEM TO BE SOLVED: To provide a rigid scope system in which a locking mechanism realizing locking and unlocking of a photographing apparatus of a rigid scope is incorporated into a bayonet mount without using an additional component such as a lever operated from outside. SOLUTION: A mount frame closure 22 having an inner flange 22b at the distal end is fixed so as to surround a rigid scope insertion part 14a formed at the front face of the photographing apparatus. At the inner flange 22b, a bayonet female part 22c for making a bayonet pawl 13c projecting from an eyepiece part 13 in a radial direction pass through is notched. Inside the mount frame closure 22, a lock ring 21 is fixed in which a recessed part 21a with which the bayonet pawl 13c engages from an axial direction is formed only at a part which is not overlapped with the bayonet female part 22c. Between the recessed part 21a and the inner flange 22b, a leaf spring 23c for biasing the bayonet pawl 13c toward the recessed part 21a is provided. COPYRIGHT: (C)2006,JPO&NCIPI
