To detect the moving speed of a car without machining an in-hoistway member in an elevator.SOLUTION: The speed detection device fitted to a car for detecting the speed of the car in a hoistway through which the car moves up and down comprises: a detection unit that image-detects the surface states of a pair of guide rails laid oppositely to each other in a hoistway along the moving path of the car; and a calculation unit that calculates a car speed on the basis of the image difference of the guide rail surfaces detected by the detection unit.SELECTED DRAWING: Figure 1

    【課題】エレベーターにおいて、昇降路内部材への加工を行わずにかごの移動速度を検出する。【解決手段】かごが昇降する昇降路内部のかごの速度を検出するかごに取り付けられる速度検出装置であり、かごの移動経路に沿って昇降路内に対向して敷設される一対のガイドレールの表面状態を画像検出する検出部と、検出部が検出したガイドレール表面の画像差分からかごの速度算出を実行する演算部と、を備える速度検出装置の提供。【選択図】 図1
