Abstract

PURPOSE:To enable accurate focussing of pick up lens and to simplify the system for small sizes system, by detecting the photo detector element which best receives the reflected light flux from the object desired to be detected for the distance, from the arrangement of a plurality of photo detection elements. CONSTITUTION:The light for distance detection is produced from the fixed light source 5, and light flux is projected with the parabola reflection mirror 5 toward the objected body OB. The light reflected is received at the photo detection lens 6 and received at the photo electric receiver 7 provided fixedly. The photo detection elements 71, 72...7n are provided corresponding to the object distance l1, l2...ln, and the reflected light flux corresponding to the object distances can independently be received by the photo detection elements. With this constitution, even if it is applied to the automatic focussing system such as cameras, the adjustment to sufficiently guarantee accurate focussing of pick up lens can be very easy.
