DRIVE DEVICE AND DISTANCE MEASURING DEVICE
FIG20 is a perspective view illustrating a structure of a base, a first magnet, a second magnet, a first facing member, and a second facing member according to Example 5
FIG20 is a perspective view illustrating the structures of the base 12, the first magnet 41, the second magnet 42, the first facing member 51, and the second facing member 52 according to Example 5. In the figure, the drive unit 20, the first coil 31, and the second coil 32 are omitted. The drive device 10 according to this example is the same as the drive device 10 according to at least one of the embodiment and Examples 1 to 4 except for the structures of the first magnet 41, the first facing member 51, and the second facing member 52. Further, the distance measurement apparatus 90 according to this example has the same configuration as the distance measurement apparatus 90 according to Example 1.

['1. A drive device comprising: a support; a first movable portion swingable in two axial directions with respect to the support; a first magnet positioned inside the first movable portion and a second magnet positioned outside the first movable portion when viewed from a first direction; and a first coil on which magnetic flux from the first magnet acts and a second coil on which magnetic flux from the second magnet acts.', '2. The drive device according to claim 1, further comprising: a magnetic member including one or more facing members facing at least one of the first magnet and the second magnet, wherein the first coil is fixed to the first movable portion, passes between the first magnet and the magnetic member, and does not pass between the second magnet and the magnetic member when viewed from the first direction, and the second coil is fixed to the first movable portion, passes between the second magnet and the magnetic member, and does not pass between the first magnet and the magnetic member when viewed from the first direction.', '8. The drive device according to any one of claims 2 to 7, wherein a second movable portion is swingably attached to the first movable portion, and the second movable portion is swingable with a first axis as an axis such that an angle of a reference surface is variable with respect to the first movable portion.']
