摘要： An actuator includes a swing portion swingable about a first axis orthogonal to a central axis extending vertically and about a second axis orthogonal to the first axis and intersecting the central axis. An angle detector includes a pair of first angle detection elements above a non-magnetic structure and extending in the second axis direction with the first axis interposed therebetween when viewed from the central axis direction, and a pair of second angle detection elements extending in the first axis direction with the second axis interposed therebetween. Each of the first angle detection elements and each of the second angle detection elements include a columnar magnetic structure between the swing portion and the non-magnetic structure in the central axis direction, and a detection coil along the outer periphery of the magnetic structure.

摘要： The present invention provides a reflector scanner including a frame, a mirror portion connected to inside of the frame via a first elastic member stretching along a second axis, a first and a second drive portions. The frame includes a frame-shaped portion and a set of bridge portions and is held turnably about a first axis. The first drive portion includes: first paired magnets disposed to be opposed to one another such that the first paired magnets interpose the frame on the first axis; a first coil wired in a first annular portion formed by one bridge portion and a portion of the frame-shaped portion at one side of the first paired magnets with respect to the one bridge portion, the one bridge portion being closer to one magnet of the first paired magnets than the mirror portion; and a second coil wired in a second annular portion formed by the other bridge portion and a portion of the frame-shaped portion at the other side of the first paired magnets with respect to the other bridge portion, the other bridge portion being closer to the other magnet of the first paired magnets than the mirror portion. The second drive portion includes: second paired magnets disposed to be opposed to one another such that the second paired magnets interpose a region between the set of bridge portions of the frame on the second axis; and a third coil wired at least in the region between the set of bridge portions of the frame-shaped portion.

摘要： A multiview side mirror device for eliminating blind spots includes a shell that is mountable to a vehicle so that a front face of the shell, which is open and substantially planar, faces a rear of the vehicle. First and second mirrors are operationally engaged to first and second actuators, respectively, which are attached to and positioned in the shell and operationally engageable to a side mirror controller of the vehicle. The first mirror is substantially planar while a front facet of the second mirror curves convexly between its opposing ends. The first and second mirrors are positioned in an upper and lower portions of the front face, respectively. The side mirror controller can selectively actuate the first and second actuators to corotate the first and second mirrors, respectively, about their respective horizontal axes, and to counterrotate the first and second mirrors, respectively, about their respective vertical axes.
