PURPOSE:To efficiently arrange respective parts without disturbing the actions of the respective parts as for the arrangement in a lighting type finder and an autofocusing assembling part in a camera and to make the camera small in size and compact. CONSTITUTION:A 1st optical system 1 for confirming the image of an object is constituted of an objective lens 2, a half mirror 3 and an ocular 4. A 2nd optical system for superposing a field frame on the image of the object is constituted of lighting means 6 and 8 illuminating the field frame, the field frame 7 transmitting a part of a light beam, the half mirror and the ocular. An autofocusing optical system which performs range-finding by projecting infrared light to the object and receiving the reflected light therefrom is juxtaposed with the lighting type finder consisting of the 1st and the 2nd optical systems. The lighting means and the field frame of the 2nd optical system are arranged between the light projecting optical system 10 and the light receiving optical system 13 of the autofocusing optical system. Then, the optical path of the 2nd optical system and the optical path of the autofocusing optical system are crossed to be arranged. |
