Claim Text:
1. A sensor device comprising: a light emitting unit that emits light; a light receiving unit that is configured to detect the light emitted by the light emitting unit; a fixing frame; a fixing bracket that supports one of the light emitting unit and the light receiving unit, and is fixedly mounted to the fixing frame; and a movable bracket that supports the other of the light emitting unit and the light receiving unit, and is movably mounted to the fixing frame; wherein the movable bracket is configured to oscillate so that the light receiving unit receives the light emitted by the light emitting unit wherein the movable bracket includes a first reference portion that is an oscillation fulcrum of the movable bracket and a first adjustment portion that allows the movable bracket to be oscillated, and the movable bracket is configured to oscillate by using the first reference portion as the oscillation fulcrum at a predetermined angle in a first direction, further comprising: an intermediate movable that is provided between the other of the light emitting unit and the light receiving unit mounted to the movable bracket and the movable bracket; wherein the intermediate movable bracket includes an engagement portion that is an oscillation fulcrum of the intermediate movable bracket, and the intermediate movable bracket is configured to oscillate by using the engagement portion as the oscillation fulcrum in a second direction crossing the first direction.
