Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a state diagnostic device for a main rope, a sheave, and/or pulleys, that is implementable at an elevator installation site.SOLUTION: Provided is a state diagnostic device M1 of an elevator having a main rope 4, a sheave 3 with a groove on its outer peripheral part in which the main rope 4 passes; and pulleys 5, 6 and 7. A hoistway 8 in which the elevator is installed, includes: an irradiation unit for irradiating at least one object among the sheave 3, the pulleys 5, 6 and 7, and the main rope 4, as a target, with light; and an analysis unit for analyzing strength of an arbitrary wavelength of reflection light reflected on a surface of the target.SELECTED DRAWING: Figure 1 【課題】エレベーター設置現場において実施可能な主索、シーブ及び／またはプーリの状態診断装置を提供する。【解決手段】主索４と、前記主索４が通される溝を外周部に備えるシーブ３、及びプーリ５、６、７を有するエレベーターの状態診断装置Ｍ１であって、エレベーターが設置された昇降路８内において、前記シーブ３、プーリ５、６、７及び主索４の少なくとも一を対象物として光を照射する照射ユニットと、前記対象物の表面で反射した反射光の任意波長の強度を解析する解析ユニットと、を有する。【選択図】図１
