Beschreibung
Zusammenfassung:	An optical distance measurement apparatus includes a casing, a light emitting unit, a mirror, a rotating unit, a light receiving unit, a window portion, and a reference angle marker. The light emitting unit emits laser light. The mirror is arranged inside the casing and reflects the laser light that is emitted from the light emitting unit. The rotating unit rotates the mirror. The light receiving unit includes a light receiving element for receiving incident light. The window portion is provided in the casing and is for emitting the laser light that is reflected by the mirror outside the casing. The reference angle marker is provided in at least either of the casing and the window portion, and is detected by the light receiving unit based on a rotation angle of the mirror being a reference rotation angle that is prescribed in advance.
