摘要： In a zoom lens device of the present invention, an aperture at a predetermined zooming step that is other than a telephoto end and a wide-angle end is smaller than apertures at the other zooming steps, and the predetermined zooming step is used only when a macro shooting mode is chosen. In the present invention, the predetermined zooming step between the telephoto end and the wide-angle end is set only for the macro shooting mode, and the aperture in the macro shooting mode is small enough to make the field depth large. Therefore, the simple and inexpensive lens device can perform the macro shooting.

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 first lens holder is connected with a rotary barrel through a helicoid mechanism, and moves in an optical axial direction when the rotary barrel rotates. A second lens holder is connected with the rotary barrel through a cam mechanism. The cam mechanism is constituted of a cam portion that is disposed on a front end surface of the rotary barrel and cam followers that are disposed on a rear end surface of the second lens holder. The cam portion is formed to have sloped surfaces inclined along a circumferential direction and these sloped surfaces are in contact with the cam followers. When the rotary barrel rotates, the cam followers shift in the optical axial direction along the sloped surfaces, thereby moving the second lens holder back and forth in the optical axial direction.

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 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.

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： In a lighting unit for projecting forward diverging light emitted from a light source, a prism is disposed forward of the center of the light source. The prism has a first light incident surface through which light emanating obliquely forward from the light source enters the prism, a total reflection surface which reflects forward in total reflection light passing through the first light incident surface, a second light incident surface which is a positive refracting surface and through which light emanating mainly forward from the light source enters the prism and a light emanating surface through which light passing through the second light incident surface and light reflected by the total reflection surface emanate from the prism. A reflecting mirror reflects mainly forward light emanating sideways and rearward from the light source.
