置計測装置。A laser beam emitter consisting of a laser emitter that is driven by a step motor to make the beam axis perpendicular to the rotation axis and emits a laser beam from one end, and a part of the object to be measured. A light-receiving element and a light-receiving element group for receiving and sensing the laser beam are installed at two different points on a light-receiving stand attached to the holder, respectively, and the light-receiving element group consists of a large number of light-receiving elements arranged in parallel in a direction perpendicular to a plane containing the two points. It consists of a light receiving section and a numerical control section which calculates a minute turning angle of the laser emitter from the number of steps of the step motor and at the same time adjusts the turning angle based on the input signal from the light receiving element, and it is capable of adjusting the absolute position of the light receiving stand. A position measuring device characterized by measuring a direction.
