An operating device has a pair of linear members () made of a shape memory alloy and contracting axially due to heat generated by electrification and generating tension in the contracting direction, a drive lever () supported to pivot about a pivot shaft (), a pair of drive rods () respectively connected to both sides of the drive lever () with the pivot shaft () being disposed between the sides of the drive lever (), and a power supply circuit for selectively electrifying the linear members (). One end of each of the linear members () is fixed to a stationary member, and the other end is connected to each of the drive rods ().

Operating device, position-switching device, and magneto-optical recording/reproducing apparatus

A brushless motor comprises a rotor which is rotatable on an axis of the brushless motor and which include permanent magnets arranged circumferentially thereon, an output member connected to the rotor to rotate with the rotor, and a stator which includes electro-magnetic coils energized in order to rotate the rotor, and has a first space which receives the output member therein and a second space which extends from the first space to the outside of the stator so that an output power of the brushless motor is transmitted from the output member to the outside of the brushless motor through the second space.
