た面発光形踏切障害物検知装置。[Scope of Claim for Utility Model Registration] (1) Consists of a projector, a movable mirror, a reflector, and a light receiver installed in the projector, with the projector located on one side of the level crossing, and the reflector and receiver located on the other side of the level crossing. The movable mirror is arranged on the side, and the movable mirror is set to reflect the light beam from the light source on a predetermined side surface on the receiver side, and the reflected light beam is received by the receiver via the reflection plate. This is because the movable mirror is placed in a position that does not block the reflected light beam transmitted between it and the reflecting plate, and the movable mirror is set to rotate in opposite directions vertically within an angular range of θ with one point as a fulcrum. A surface-emitting type level crossing obstacle detection device. (2) A movable mirror is housed in the projector, and the movable mirror is rotated vertically in an angle range of θ with one point as a fulcrum, and the light beam from the light source is directed to a predetermined position on the receiver side of the movable mirror. A surface-emitting type level crossing obstacle detection device equipped with a light projection mechanism that is set to project light onto the side and projects a light beam from the projector to the receiver side in an angle range of θ.
