Abstract

PURPOSE: To enable high-accuracy focus detection by bending an optical path through a reflecting mirror, arranging one element of a detecting means on this optical path, and moving the reflecting mirror in the same moving direction with the focus adjusting lens of a photographic system for the focus detection of the photographic system.
CONSTITUTION: The reflecting mirror 6 is introduced as part of a photodetecting means, the optical axis L2 of a photodetection lens 5 is bent, and the photodetection part 7 which is one element for focus detection is arranged on the bent optical path on a substrate 8. Thus, the focus group 1a of the photographic system 1 and the reflecting mirror 6 are both moved in the same direction. Consequently, a focus detector is obtained which is simplified in mechanism and capable of high-accuracy focus detection while maintaining the size of the whole camera with good balance.
