PHOTOMETRIC ELEMENT HOLDING STRUCTURE FOR LENS SHUTTER CAMERA

摘要

PURPOSE:To hold two photometric elements with good position accuracy by simple structure by forming fitting parts where photodetectors for photometry are held at positions corresponding to photodetection lenses provided to a camera main body and holding the photodetectors for photometry integrally by the frame of a lens shutter unit. CONSTITUTION:The photodetectors 26a and 26b for photometry are fitted to the fitting parts 27 and 28 provided to the frame 23 of the lens shutter unit 22. Then the lens shutter unit 22 is fixed to the body 13 of the camera to fix the photodetectors 26a and 26b to the body 13 at the same time. At such a time, the photodetectors 26a and 26b are positioned corresponding to the photodetection lenses 29a and 29b provided to the front cover 11 of the camera. Consequently, the fitting of the photodetecting elements for photometry to the camera body is facilitated and the photodetectors 26a and 26b themselves can be mounted while maintaining specific position accuracy.
