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 display arrangement for the charging condition in a strobing circuit of a photographic camera with a built-in strobe-flash device includes a display lamp, serving to indicate that charging in the strobing circuit has been completed, and a controller for a main switch of the camera. The display lamp is covered by the controller as the controller is moved to turn the main switch OFF, and uncovered again as the controller is moved to turn the main switch ON, in order to bring the camera in a state ready for photographing. Thus, the display lamp is invisible even though the display lamp is on when the main switch is in the OFF state. In this manner, the strobing circuit can be arranged so as to be always charged, and thereby to make charging in the strobing circuit independent from the ON-OFF state of the main switch.

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 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： Modes of a camera are classified into groups according to their type. On an LCD panel, the different groups are displayed on different rows, and modes to be selected out of each group are displayed in different columns. Group selection is accomplished by vertically manipulating a selector button, and mode selection out of each group is accomplished by laterally manipulating the selector button. This makes possible displaying of selectable modes classified by group on the LCD panel in a way perceivable at a glance. Furthermore, the choice of a group and that of a mode within each group are matched in the mode display arrangement to facilitate the operation for mode selection.

摘要： The present invention provides a camera which can release creep of a moving member, preventing the moving member disposed within the camera from breaking due to creeping. The camera includes a barrier base rotating in response to the driving force of a motor so as to open/close a barrier upon rotation, and a stopper for restricting the moving area of the barrier base. When opening/closing the barrier, the barrier base is rotated until it abuts against the stopper, and then is rotated in reverse so as to be separated from the stopper. As a consequence, the barrier plate can be prevented from breaking upon creeping when pressed by the stopper for a long time.
