成の位置検出装置。A light source that moves together with a moving object, and a plurality of comb teeth that are provided along a path of movement of the light source and have gradually different lengths, and are arranged oppositely so that the comb teeth of approximately corresponding lengths mesh with each other. a photoconductive material film in a meandering strip pattern formed such that the meandering length is gradually different between the set of comb-teeth-shaped foils; It consists of a resistive element that forms an electrical resistance between the strip-shaped foils, and a spot of light from the light source that is approximately longer than the maximum meandering length of the photoconductive material film of the meandering strip pattern increases the resistance as the object moves. moving on the element, and the light-receiving area of the photoconductive film changes in accordance with the movement of the object, and the electrical resistance value of the comb-teeth of the set changes,
A position detection device configured to detect the position of the object based on the electrical resistance value.
