To provide a rope vibration period measurement device, etc., for an elevator, which are able to easily calculate accurate tension of each rope.SOLUTION: When a rope used to raise or lower a cage in an elevator 1 vibrates due to the application of force to the rope, a measurement device 10 measures the period of vibration of the rope. The measurement device 10 comprises: a light receiving unit that receives light from the rope; and an information processing unit 16 that specifies, based on light received by the light-receiving unit, a one-side moment at which the rope reaches a one-side position where the rope changes the direction of movement in vibrating motion and the-other-side moment at which the rope reaches the other-side position where the rope changes the direction of movement in the vibrating motion.SELECTED DRAWING: Figure 2

    【課題】エレベーターにおいて各ロープの正確な張力を算出し易いエレベーターのロープ振動周期測定装置等を提供すること。【解決手段】測定装置10は、エレベーター1においてカゴを昇降するのに用いられるロープが力を付与されることで振動している際に、そのロープの振動の周期を測定する。測定装置10が、ロープからの光を受光する受光部と、ロープが振動運動において移動方向を変える一方側位置に到達した一方側時、及びロープが振動運動において移動方向を変える他方側位置に到達した他方側時を、受光部が受信した光に基づいて特定する情報処理装置16と、を備えるようにする。【選択図】図2
