特徴とする相対位置検知装置。 A plurality of pairs of light-emitting elements and light-receiving elements are arranged in a direction orthogonal to the direction of relative displacement of the two members on one of the two members that are relatively displaced, and each A light-shielding member is provided between the light-emitting element and the light-receiving element that form a pair, and records optically readable position information.
In a relative position detection device that detects the relative position of the two members by a combination of a light receiving element that receives light information from the light shielding member, the light emitting element and the light receiving element forming the pair are arranged such that at least the light receiving element are set at positions shifted by a distance that do not receive light emitted by adjacent pairs of light emitting elements, and positional information of the light shielding members corresponding to the pair of elements is set at positions shifted by the same distance in the same direction. relative position sensing device.
