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.

摘要： The present invention provides a lens driving apparatus which can prevent a lens barrel from increasing its size and cost while making it possible to detect the position of a movable lens group. A first lens group, a second lens group, and a third lens group are disposed along an optical axis, among which the second lens group is a movable lens group movable along the optical axis. A second lens frame holding the second lens group is formed with a detection plate having a predetermined width in the direction of optical axis. A detector detects passages of both end portions of the detection plate, whereby the position of the second lens group can be detected.

摘要： The present invention provides a lens driving apparatus which can accurately detect the position of a movable lens group while preventing the apparatus from increasing in size and cost by using a simple position detecting sensor. A first lens group, a second lens group, and a third lens group are disposed along an optical axis, among which the second lens group is a movable lens group and is movable along the optical axis. The second lens group is movable at two or more different speeds. When the second lens group passes a reference position, it is moved at a speed which is not the highest of the different speeds. As a consequence, the position of the second lens group can be detected accurately.

摘要： A self-photographing method for an autofocus camera, wherein, upon depression of a shutter release button, the subject distance data are detected a plurality of times at periodic intervals, and a predetermined exposure operation, that is, an actual shutter release operation is automatically executed using the autofocus system when the detected subject distance data have changed from each other. The distance data are repeatedly detected and compared with each other until these distance data differ from each other. If the distance data have been equal for a predetermined time interval from the shutter release button depression, then the actual shutter release operation is executed, or is called off and the self-photographing is terminated. It is preferred that the detected change of distance be a decrease of distance, indicating that the photographer has stepped into the picture, whereupon the measured distance becomes his distance in place of the background distance.

摘要： A camera is disclosed which is capable of winding and rewinding a film and adjusting a focal distance by use of a single motor. In the camera, the forward rotation of the motor is used to wind the film, and when the film winding operation is completed after termination of photographing, on detecting the end of the film, a torque detect mechanism switches a planetary clutch mechanism to connect the motor with a film rewinding mechanism. Thus, it is possible to perform both the film winding and rewinding operations by use of the rotation of the motor in the same direction. Also, when, with the planetary clutch mechanism connected with the film winding mechanism, the motor is rotated reversely, then the power transmission system is switched over to a focal distance varying mechanism, whereby the focal distance can be adjusted.

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.
