摘要： A chopping secondary mirror system is provided, in which magnetic circuits of a driving motor for causing a secondary mirror to chop about its rotation axis are mounted to the secondary mirror via a driving motor mounting so that the magnetic circuits function as a balancing mass to position the center of gravity of a whole chopping section on said rotation axis. The driving motor mounting is secured to the secondary mirror at the center of the secondary mirror. Leaf springs are used as vibration damping springs of a reaction force compensator.

摘要： Provided is a reflector oscillating apparatus in which the positions of a reflector and a compensating plate are detected so as to perform positioning with a high degree of positional accuracy (closed-loop control). Further, since the reflector and the compensating plate are driven by a couple of forces, no reaction forces by drive forces are applied to a rotary shaft and a support section, and accordingly, it is possible to enhance the positioning accuracy and to realize a short transient time and a large amplitude. Further, the magnetic circuit is commonly used so that the dimensions of a motor, that is, the height thereof in particular, can be reduced, irrespective of a large drive force. Accordingly, the reflector oscillating apparatus can be greatly miniaturized. Further, by commonly using the magnetic circuit, the impedance of the coil can be reduced, thereby it is possible to drive the apparatus at a high speed with a low drive voltage.
摘要翻译：提供了一种反射器振荡装置，其中检测反射器和补偿板的位置，以便以高位置精度（闭环控制）进行定位。此外，由于反射器和补偿板由一对力驱动，因此驱动力没有反作用力施加到旋转轴和支撑部，因此，可以提高定位精度并实现短瞬时时间和幅度较大。此外，通常使用磁路，使得马达的尺寸，特别是其高度可以减小，而与大的驱动力无关。因此，反射器振荡装置可以大大地小型化。此外，通过通常使用磁路，可以减少线圈的阻抗，从而可以以低驱动电压高速驱动装置。

摘要： A carriage assembly for a disc operating apparatus comprising a frame, a carriage movably supported in the frame relative to the disc, an optical lens or magnetic head mounted on the carriage for recording and reproducing information on the disc, and a radial guide arrangement permitting movement of the carriage in a radial direction relative to the disc. The assembly also comprises a radial drive arrangement including an electromagnetic coil mounted to the carriage and a permanent magnet mounted to the frame. The permanent magnet is electromagnetically coupled with the electromagnetic coil for driving the carriage in the radial direction of the disc. The electromagnetic coil includes two sections which sandwich the carriage and are shaped to come into contact with each other at both sides thereof, whereby the cross section of the electromagnetic coil is hexagonal in a plane parallel to a surface of the disc. As a result, the dimensions in the radial direction of the carriage assembly are decreased.
