ることを特徴とする移動体の位置検出機構。[Claims for Utility Model Registration] A first reflector 2 attached to the upper surface 1A of the moving body 1 that moves in a straight line, a second reflector 3 attached to the lower surface 1B of the moving body 1, and a plurality of holes 4A. A hole is formed corresponding to the detection position of the moving body 1 and fixed parallel to the moving direction of the moving body 1, and the portion other than the hole 4A blocks the path of light through the first reflector 2 and the second reflector 3. A light shielding plate 4, a light projector 5 that projects light onto the first reflector 2, the light projected from the projector 5 is reflected by the first reflector 2, and the reflected light from the first reflector 2 passes through the hole 4A. and a light receiver 6 that emits light onto the second reflector 3 and receives the reflected light of the second reflector 3, and when there is a light reception output of the light receiver 6, the movable body 1 is at the detection position. A position detection mechanism for a movable body, characterized in that when it is determined that there is a light receiving output from the light receiver 6 and there is no light reception output from the light receiver 6, it is determined that the movable body 1 is not at the detection position.
