PROBLEM TO BE SOLVED: To provide a theatrical light optical axis inspecting device in which an inspection space can be saved while securing the distance required for inspecting an optical axis of a theatrical device.SOLUTION: An optical axis inspecting device 1 for a theatrical light comprises a light incidence section 13 which accepts light emitted from a theatrical light 2 that is an inspection object, a light receiving section 4 which receives the light made incident from the light incidence section 13 and outputs a signal corresponding to the light, light reflectors 5-9 between the light incidence section 13 and the light receiving section 4 for reflecting light on a path of light made incident from the light incidence section 13, and a casing 11 formed from a material through which light is not transparent, so as to cover the path of light. The light reflectors 5-9 are disposed within the casing 11 in such a manner that the path of light becomes a predetermined length. |
