WIPO Patent Application WO/2022/181640
Kind Code:
A1
Abstract:
A reflector drive device (101) that comprises a reflector holding member (4) that can hold a reflector (1) that bends light, a first support member (5) that supports the reflector holding member (4) such that the reflector holding member (4) can swing around a swing axis (SA1), a second support member (6) that supports the first support member (5) such that the first support member (5) can swing around a swing axis (SA2) that has an axial direction that is orthogonal to the axial direction of swing axis (SA1), a first drive mechanism (MD1) that makes the reflector holding member (4) swing around swing axis (SA1), and a second drive mechanism (MD2) that makes the first support member (5) swing around swing axis (SA2). The first drive mechanism (MD1) includes a magnetic field generation member (7) and a coil (8) that is opposite the magnetic field generation member (7). The magnetic field generation member (7) and the reflector holding member (4) are arranged so as to be incapable of moving relative to one another, and the coil (8) and the second support member (6) are arranged so as to be incapable of moving relative to one another.
