PROBLEM TO BE SOLVED: To provide a diagnosing device with which it is possible to prevent an observation error or observation mistake arising from subjective preconception or inaccurate standards in the observation of a working model, etc., and perform objective diagnosis.SOLUTION: A diagnosing device 100 comprises a line light emission unit 502 for irradiating a linear laser beam toward the top face of a working model place horizontally, a dot light emission unit 501,and a control unit 500 for controlling the on/off of lighting of each of the emission units. Each of the line light emission unit 502 and the dot light emission unit 501 is disposed in the diagnosing device 100 so that, with one of the irradiation position of the linear laser beam on the top face of the working model and the irradiation position of a dot-shaped laser beam defined as a point of reference, laser beams for the other are irradiated by superimposition.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2020,JPO&INPIT【課題】作業模型などの観察における主観からの思い込み、あるいは不正確な基準から生じる観察誤差や観察ミスなどを防ぎ客観性を有する診断を行うことができる診断装置を提供する。【解決手段】診断装置１００は、水平に載置された作業模型の上面に向けて線形状のレーザ光を照射するライン光出射部５０２、ドット光出射部５０１、出射部それぞれの点灯又は消灯を制御する制御部５００を有する。ライン光出射部５０２、ドット光出射部５０１それぞれは、作業模型の上面における線形状のレーザ光の照射位置、又は、点形状のレーザ光の照射位置のいずれか一方を基準にして他方のレーザ光が重畳して照射されるように診断装置１００に配設される。【選択図】図１
