Claims

[Claims for Utility Model Registration] In an optical telemeter device that measures information on a rotating body that is attached to a fixed body so as to be able to rotate relative to it, a secondary coil that is attached to the rotating body and connected to a power supply circuit and a secondary coil that is attached to the fixed body and A rotary transformer configured with a primary coil that is inductively coupled to the secondary coil in a non-contact manner and that has a different winding diameter than the secondary coil and is arranged concentrically with the secondary coil; are arranged in parallel along the axial direction of the rotating body and are divided into annular sections between the fixed body and the rotating body, and an optical transmission line that is attached to the rotating body and opens to the optical transmission line and is connected to the conversion circuit. a light-emitting element that emits light in response to a transmitted signal; and a non-contact light-emitting element that is open to the optical transmission path, is attached to a fixed body, and is arranged in a relative positional relationship that does not receive direct light from the central beam of the light-emitting element. An optical telemeter device consisting of a light receiving element optically coupled to a light receiving element.
