有して成る接触式位置検出装置。 A movement amount detection means for measuring the movement amount of a workpiece attached to a feeding table and fed in one direction from a preset origin position, and a front end of the workpiece reaches a position a certain distance from the origin position in the movement direction of the workpiece. The limit sensor includes a sense rod that is arranged to be movable forward and backward in the direction of movement of the workpiece and is pressed against the front end of the workpiece in the direction of movement of the workpiece, and a sense rod that is moved at a predetermined distance from the origin position. A photoelectric switch is provided which forms a light beam in a direction perpendicular to the direction of movement of the sense rod at a remote position and obtains a detection signal when the light beam is interrupted by a part of the sense rod, and the detection signal is obtained from the origin position. A contact type position detection device comprising calculation means for calculating the distance from the origin position to the front end of the workpiece based on the amount of movement of the feed table until the workpiece is moved.
