Abstract

PURPOSE:To make easy the light axis alignment by changing the factor of amplification of projected or received light amount in interlocking with the slide of the projective element and to obtain stable detection characteristics through automatic sensitivity adjustment. CONSTITUTION:The photo detector 2a is provided at the focus of the lens 6, the projective element 1a which can be slided on the light axis at the back of the element 2a, and the sensitivity adjuster 8 changing the amplification factor of projected or received light amount in interlocking with the slide of the element 1a is provided. Thus, the alignment of light axis is easily made with the slide of the element 1a, automatically the sensitivity adjustment can be made in interlocking with the operation of the light axis adjustment, and stable detection characteristics can be obtained.
