摘要： An actuator using an electromechanical transducer suitable for an apparatus where the magnitude of the load differs depending on drive directions. An apparatus using the actuator in which the actuator is arranged such that a direction of a further advantageous and further efficient displacement characteristic in elongation displacement characteristic and contraction displacement characteristic of the electromechanical transducer, is made to coincide with a drive direction where the load is larger. In the case of a mechanism of a camera for driving a correcting lens, an X-axis actuator and a Y-axis actuator are arranged at a base frame. The correcting lens is driven in the X-axis direction and the Y-axis direction. The Y-axis actuator is arranged such that a direction of a further advantageous displacement characteristic of an electromechanical transducer of the Y-axis actuator is made to coincide with a positive direction of the Y-axis where the load is larger in order to drive the correcting lens in the positive direction of the Y-axis against gravitational force.

摘要： Light source 1 is mounted to camera body 10 via supporting member 2. The image from optical system 11 is recorded on the film inside photo-taking frame 12. The light beam from the light source is recorded in an area outside the photo-taking frame as its brightness or wavelength or both are made to change over time. Image processing is conducted at the time of development based on this recorded data in the area outside the photo-taking frame so that the information pertaining to shaking may be canceled out.

摘要： A controller determines the presence/absence of change in focal length caused by a zooming operation, and determines the necessity of correcting image plane shift caused by said change in focal length. Blur correction is prohibited when executing correction of image plane shift, and image plane shift is corrected by calculating the amount of movement of the focusing lens based on set focal length information, current position information of the focusing lens, and correction information stored in memory. When correction is unnecessary, the controller determines blur correction is permitted when the drive of the focusing lens ends, and executes the correction. The blur correction and the image plane shift correction are not executed simultaneously.

摘要： A device, employing a piezoelectric element, drives an object such as a lens in a camera, in which it is possible to increase a speed of a moving part to drive the object without increasing a maximum value of pulse voltage inputted to the element. The device has the element one end of which is fixed to a base seat; a rod one end of which is fixed to the other end of the element; a moving part which is frictionally mounted on the rod; and a resonant induction part which is connected to the other end of the rod. The resonant induction part has a spring part one end of which is connected to the rod, and a weight part which is connected to the other end of the spring part. The rod resonates under an effect of the resonant induction part so as to increase the amplitude of the vibrating rod when the pulse voltage applies to the element; thus increasing the speed of the moving part relative to the base seat.

摘要： A compact film player has a picture reproducing unit and an information reading unit capable of reading a photographing information on each frame of the film. When a developed film is fed in an inlet of the picture reproducing unit in a prescribed direction, a scan mirror scans a picture provided on the film perpendicularly to the feed direction, so that a line sensor takes the picture every line. The line sensor and the scan mirror read two-dimensional pictures provided on the film. When the picture of the frame previously read is on display, the scan of the next frame is effected.

摘要： An apparatus for driving a collapsible lens mount having several telescoping segments includes, for each movable segment, a transducer that expands and contracts responsive to a wave pulse and a drive shaft coupled to the transducer. By varying the wave pulse conditions, the expansion and contraction are made to occur at different rates. A coupling member on each segment frictionally engages the drive shaft and transmits movement of the drive shaft during relatively slow drive shaft movements to the lens segment. The apparatus may also include a lens hood driven by the transducer and drive shaft apparatus of the invention.

摘要： An apparatus has a member to be driven, an actuator for driving the member, a position detector and a controller. The actuator drives the member to move by an amount proportional to a given number of pulses. The position detector detects a position of the member in predetermined detection steps. The controller determines in steps smaller than the predetermined detection steps a target position up to which the member is to be moved. Then, it controls the actuator up to a detection-step position before the target position by closed-loop control in accordance with a detection result from the detector. Further, it controls the actuator from the detection step position to the target position by open-loop control.
