PROBLEM TO BE SOLVED: To avoid the interference between a shutter integrated with a lens frame and a transmission photosensor, and to reduce the exterior dimensions. SOLUTION: The shutter 42 is installed in a second lens frame 14. The first transmission photosensor 17 is installed in the inner face of an external wall 5a, on the photographed object side of a first optical block case 5, and at the same time, a second transmission photosensor 18 is installed in an external wall 5b of the CCD light-receiving side. A first light-shielding plate 19 is installed on the surface of the photographed object side of a first lens frame 11, and at the same time, a second light-shielding plate 20 is arranged at one side of a light-shielding plate installing member 43 and the member 43 is installed in the bottom of the second lens frame 14. In this way, the second light-shielding plate 20 is arranged on the side opposite to the second lens frame 14 side for the shutter 42, and the interference between the shutter 42 and the second transmission photosensor 18 is avoided. Also, a part of the projection plane of the second transmission photosensor 18 and the shutter 42, to the surface perpendicular to an optical axis, is arranged so as to overlap with each other, thereby reducing the length in the direction perpendicular to the optical axis.
