Abstract
A galvanometer mirror is capable of inclining a reflective mirror around an axis, and has springs. An end of the spring in the vicinity of a movable part is inserted into a second holder, and is then electrically connected to each of terminals. Flexible cables are soldered to these terminals, respectively. Thus, coils are able to receive currents passing through the flexible cables and the terminals, respectively.
Claims6
A galvanometer mirror comprising:
- a movable part having an optical element and a plurality of coils;
- a supporting part for supporting said movable part so that said movable part can be inclined around an axis;
- and
- a fixed part having at least a magnetic circuit for applying a magnetic field to said coils,
- wherein said supporting part has an electric conductive elastic part that inclines said movable part around said axis as a result of torque around said axis caused by said magnetic field and supplies electric power to said coils.
