Abstract: A lens barrel assembly for use with a digital still camera includes an outer barrel having a front end and a rear end. An inner barrel is inserted in the outer barrel in an optical axis direction. The outer barrel moves forwards relative to the inner barrel, to shift between a short size position and a long size position, and when in the short size position, shifts from the inner barrel at a smallest shifting amount, and when in the long size position, shifts from the inner barrel at a largest shifting amount. A vent is formed in the outer barrel, and disposed close to the front end. A filter is water-impermeable and air-permeable, and secured to the vent in a closed manner. Also, a vent cover is secured to the outer barrel, for covering the vent.

Abstract: A first drive shaft is disposed with a first piezoelectric element at one end and a second piezoelectric element at the other end. A second drive shaft is disposed with the second piezoelectric element at one end and a third piezoelectric element at the other end. First and second lens holding frames are frictionally engaged with the first and second drive shafts respectively in a slidable manner. The first, second and third piezoelectric elements are expanded and contracted according to a drive signal and move the first and second lens holding frames in an axial direction respectively. When the moving velocity of the first and second lens holding frames are reduced, the phase difference between the drive signals, which are output to the respective piezoelectric elements, is adjusted so that the moving velocity becomes higher.

Abstract: 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.

Abstract: A heat sink is attached to a subject-side end portion of a barrel body of a lens barrel. The heat sink is provided with a large number of radiation fins formed in whorl. A heat pipe is disposed between the heat sink and a mount-side end portion of the barrel body. A CCD is fixed to the mount-side end portion of the barrel body. Heat of the CCD is transferred to the heat pipe via the mount-side end portion. Successively, the heat is efficiently transferred to the heat sink by the heat pipe. The heat having been transferred to the heat sink is efficiently radiated into the air by the whorl-like radiation fins regardless of conditions of the lens barrel.

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.
