Claims

[Claims for Utility Model Registration] A reflective position detection device for detecting the position of a target mark on a detection surface having a target mark having a reflectance different from that of surrounding parts, which comprises a plurality of light receiving optical fibers at least at the detection end. are arranged closely so that the tip surfaces thereof have a predetermined shape, and the tip surfaces of the plurality of light emitting optical fibers are arranged on the outer periphery in a predetermined positional relationship with respect to the light receiving optical fibers, an optical fiber assembly including a plurality of light-receiving optical fibers and a plurality of light-emitting optical fibers integrally formed; a light source provided opposite to the rear end surface of each light-emitting optical fiber of the optical fiber assembly; a photoelectric element provided facing each rear end face of the light-receiving optical fiber; a calculation means for processing output signals from each of the photoelectric elements to output a positional deviation signal; and a detection end of the optical fiber assembly. a moving means for relatively moving the target mark on the detection surface in the vicinity of the target mark.
