Abstract: A light path adjustment mechanism includes a bracket, a light valve, a carrier, a first axis, a second axis and an optical plate member. A surface normal of a surface of the light valve crosses the bracket to define an intersection closest to the surface of the light valve, and the bracket has an end point furthest from the intersection measured in the direction of the surface normal. A distance between the intersection and the surface measured in the direction of the surface normal is smaller than a distance between the intersection and the end point measured in the direction of the surface normal.

Abstract: A driving device that can be prevented from being damaged is provided. Abase member includes a frame-shaped part that rotatably supports a movable part via a shaft part provided on an inner circumference side of the frame-shaped part, and an elastic structural part extending to an outer circumference side of the frame-shaped part. The elastic structural part of the base member is joined to the pedestal, and this allows the difference in amount of thermal deformation generated on the base member and the pedestal to be absorbed by deformation of the elastic structural part, thereby preventing the driving device from being damaged.

Abstract: A method for controlling a planar drive system with a stator unit and a rotor includes moving the rotor to a rotational position on the stator unit. In the rotational position, each magnet unit of the rotor covers a coil group of the stator unit which is not covered by any other magnet unit of the rotor, in each orientation of the rotor relative to the stator unit. The method includes actuating the coil groups which are covered by the magnet units of the rotor in the rotational position, generating a stator magnetic field by each actuated coil group, and rotating the rotor about an axis oriented perpendicular to a surface of the stator unit by a predetermined angle, by way of the stator magnetic fields of the actuated coil groups covered by the magnet units of the rotor. A planar drive system is adapted to perform the method.

The driving yoke is disposed to oppose the driving coil in the direction orthogonal to the first direction. When current is applied to the driving coil, the movable body is configured to move in the direction orthogonal to the first direction by electromagnetic interaction between the driving coil and the driving yoke.
