To provide a technique which allows users to easily recognize the state of measurement by a displacement measurement device which includes a sensor head with no electric circuits.SOLUTION: A displacement measurement device 1 includes: an optical system; a sensor head 30 with no electric circuits; a controller 100; a first optical fiber for conveying illumination light from a light projector 10 to the sensor head 30; and a second optical fiber for conveying reflected light from the sensor head 30 to the controller 100. The controller 50 has a first mode for measuring the distance between the sensor head 30 and the reflection position and a second mode for showing whether the distance between the sensor head 30 and the reflection position corresponds to the middle of a defined distance range according to the state of light projection by the light projector 10.SELECTED DRAWING: Figure 1 【課題】電子回路を有していないセンサヘッドを含む変位計測装置の計測状態をユーザが容易に認識するための技術を提供する。【解決手段】変位計測装置１は、光学系を有し、かつ電子回路を有していないセンサヘッド３０と、コントローラ１００と、投光部１０からの照射光をセンサヘッド３０に伝達する第１の光ファイバと、センサヘッド３０からの反射光をコントローラ１００に伝達する第２の光ファイバとを備える。制御部５０は、センサヘッド３０と反射位置との間の距離を計測する第１のモードと、センサヘッド３０と反射位置との間の距離が規定距離範囲の中央部にあるかどうかを投光部１０の投光状態によって示す第２のモードとを有する。【選択図】図１
