发明名称 Distance measuring device of camera
摘要 In a distance measuring device of a camera, a distance measuring optical system unit has light-emitting and light-receiving elements for distance measurement. The distance measuring optical system unit is rotated from one end of a photographing screen to the other end thereof to perform a distance measuring operation. The distance measuring optical system unit is rotated and stopped in a set distance measuring range by a cam rotated by a DC motor and a driven arm portion of the distance measuring optical system unit. Distance measuring object ranges of the distance measuring optical system unit are switched by a switch. For example, the distance measuring object ranges are set with respect to many-point distance measurement or one-point distance measurement.
