第１項記載の変位量測定装置。[Claims for Utility Model Registration] (1) A support having a slit and connected to an object whose displacement is to be measured and movable in accordance with the displacement of the object, and a light beam directed toward the slit of the support. It consists of a light source that can emit light and an optical position detector that can receive the light irradiated from the light source through a slit, and detects changes in the position of the incident light on the optical position detector caused by the movement of the slit as the object is displaced. and is configured to measure and display the amount of movement of the position, and further comprises a control circuit that controls the amount of light from the light source so as to keep the total amount of light incident on the optical position detector constant. Quantity measuring device. (2) The displacement measuring device according to claim 1, wherein the measurement display is a digital display.
