摘要： A stepping motor comprises first to third coil portions and first to second rotors. The first rotor has a cylindrical shape and a circumferential surface thereof is magnetically-polarized so as to alternately arrange south poles and north poles. The first rotor is disposed inside the first and second coil portions, and is rotated by magnetic fields generated at a time when the first and second coil portions are energized. The second rotor has a disk shape and a surface thereof is magnetically polarized so as to alternately arrange south poles and north poles. The second rotor is disposed such that edge areas of both surfaces thereof are interposed between the second and third coil portions. The second rotor is rotated by magnetic fields generated at a time when the second and third coil portions are energized.

摘要： A lens frame holding a taking lens is movably connected to a driving shaft via a connector. A guide member is disposed at a lower portion of the lens frame so as to separate from the connector by about 180 degrees around an optical axis. The guide member is movably attached to a guide rod. A light emitter is disposed on a lateral side of the lens frame so as to separate from the connector by about 90 degrees around the optical axis. The light emitter applies the light to a light receiver of a line sensor confronting the light emitter. The line sensor sends a light-reception signal, which is outputted from the light receiver, to a lens-position controller. Positional information of the taking lens is obtained on the basis of the light-reception signal so that a position of the taking lens is accurately detected.

摘要： 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.

摘要： A piezoelectric actuator includes a piezoelectric element, having first and second ends, for expansion or contraction to shift in response to a drive signal. A drive shaft is frictionally engaged with an engageable portion of a lens unit, has first and second axial ends, for shifting together with the piezoelectric element by contact between the first end and the first axial end, to move the engageable portion linearly upon expansion and contraction of the piezoelectric element with a difference between its expanding and contracting speeds. A retaining frame includes a first support panel, provided with the second end secured thereto, for supporting the piezoelectric element. A second support panel is provided with the second axial end secured thereto, for supporting the drive shaft. A biasing panel portion of the second support panel biases the drive shaft to press the first axial end on the first end of the piezoelectric element.

摘要： An imaging device moves a taking lens in an optical-axis direction by a hollow stepping motor of a claw-pole type comprising a disk-shaped hollow magnet and stators. The magnet is disposed in a direction perpendicular to the optical axis. The stators are respectively adjacent to both surfaces of the magnet in the optical-axis direction. When the magnet is rotated, attractive force caused by the respective stators is applied in the optical axis direction. It is prevented that the magnet and a rotary barrel are attracted in the direction perpendicular to the optical axis. Thus, electric power consumption is prevented from increasing due to friction with upper and lower covers, and abnormal noise is prevented from occurring due to the friction.
