  • Publication number: 20220099833
    Abstract: A mirror module includes a pair of deflecting mirrors which deflect a transmission wave and a reflected wave in a direction in accordance with a rotation angle of a reflecting surface and rotates in accordance with drive of a motor. A dividing plate divides the pair of deflecting mirrors into two portions of a transmission deflecting portion and a reception deflecting portion. Each of the pair of deflecting mirrors includes shielding portions through which passage of the transmission waves is suppressed on at least one of a side surface closer to a transmissive window in a state where the reflecting surface faces the transmitting portion out of both side surfaces located across a rotational axis at the transmission reflecting portion or a side surface farther from the transmissive window in a state where the reflecting surface faces the receiving portion out of both side surfaces located across the rotational axis at the reception deflecting portion.

  • Publication number: 20220099811
    Abstract: In a ranging device, a mirror support has a pair of deflection mirrors installed on both surfaces. A pair of partition plates are installed to bookend the pair of deflection mirrors and the mirror support in a direction normal to the reflective surfaces of the deflection mirrors. A clip grips and secures the pair of deflection mirrors, the mirror support, and the pair of partition plates. A motor rotates these components. Each partition plate includes a plate-like portion extending along a plane normal to the axis of rotation so as to partition a corresponding reflective surface into two regions, and an upright portion extending along the corresponding reflective surface from a position on the plate-like portion where the plate-like portion faces the corresponding reflective surface. The clip grips the pair of deflection mirrors and the mirror support via the upright portion in the direction normal to the reflective surfaces.
