摘要： A camera having a sprocket with a pair of cogs formed on a periphery for engaging a filmstrip having a row of perforations separated at alternate short and long intervals. The periphery is divided by the cogs into a frictional engaging section which provides frictional engagement of the periphery with the filmstrip and a mechanical engaging section which provides mechanical engagement of the cogs with the perforations. A shutter charging mechanism is operated by rotation of the sprocket driven by the filmstrip through the mechanical engagement between the filmstrip and at least part of the mechanically engaging section of the sprocket. A switch over mechanism disconnects the sprocket and the shutter mechanism in response to rewinding the filmstrip and a locking mechanism prevents reverse rotation of the sprocket in a specific position.

摘要： A camera with a variable focus lens device, in which a lens position detecting device detects the focal length of the photographing lens from the amount of movement of a movable member that is capable of being rectilinearly advanced and retracted along the optical axis of the photographing lens, in order to provide an autofocusing function to accurately focus upon an object. Thus, the focal length can be detected in a simplified manner, and the influence of errors during assembly of the components of a photographing lens driving system can be minimized. A flare preventing mask effectively prevents flare occurrence in correspondence to variations in the position of the photographing lens. The lens retaining structure simplifies the assembly of the front lens group into a movable lens mount, and reduces the size and weight of the camera. A position sensor is coupled to the movable member which moves while maintaining a predetermined relation with the movement of the photographing lens, and the position of the photographing lens is detected from the amount of movement of the movable member. A key member prevents rotation of the movable lens mount and so allows the movable lens mount to be advanced or retracted a lesser distance than the movable lens mount. The flare preventing mask is mounted on the key member. A rear focusing type autofocusing mechanism is provided by inserting a holder retaining the front lens group into the movable lens mount from the front end of the lens mount.

摘要： A panoramic camera is provided with a masking mechanism. When the panoramic size is designated, the masking mechanism partially masks an exposure aperture that otherwise would create a full size picture, thereby to form a panoramic picture. On a rear door of the camera are mounted first and second data recorders. When the full size is designated, the first data recorder records numerical data on the first picture and in a larger size. When the panoramic size is designated, the second data recorder records numerical data on the second picture and in a smaller size. The full-size data are positioned outside the area of the panoramic picture.

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.
