Abstract: A switching device is provided that includes a switching mechanism unit and a switch drive control circuit. In the switching device, an operating member is maintained in an ON position by the sucking force of a permanent magnet and a yoke, despite the pushing force of a biasing unit, when the permanent magnet is in an ON position. The yoke is magnetized in such a manner as to reduce the magnetic force of the permanent magnet, when a coil wound around the yoke is energized by the switch drive control unit. The operating member and a switching member are moved from the ON position to the OFF position by virtue of the pushing force of the biasing unit, thereby shutting a feed line.

Abstract: A piezoelectric actuator having a frame portion includes a drive shaft for frictional engagement with an engageable barrel arm of a lens unit. First and second piezoelectric elements are supported on the frame portion, and provided with first and second ends of respectively the drive shaft. A drive pulse generator supplies the piezoelectric elements with a drive signal to expand or contract the piezoelectric elements, and moves the engageable barrel arm in an axial direction by an alternately repeating sequence of shifting the drive shaft at low and high speeds in the axial direction. In the shifting at the high speed, the piezoelectric elements shift the drive shaft in a backward direction quickly, to move the drive shaft in the backward direction relative to the engageable barrel arm being stationary with inertial force.
