    摘要: It is an object of the present invention to provide a very compact zoom assembly with a minimum number of parts. Another object of this invention is to provide a zoom assembly which does not require guide rods and utilizes with only one motor for both zooming and focusing. Briefly summarized, according to one aspect of the present invention, a zoom assembly includes a zoom lens defining an optical axis. This zoom lens is capable of operating in a plurality of different zoom positions and of focus adjustment for different object distances in each of the zoom positions. The zoom positions are (i) two extreme zoom positions (a wide angle position and a telephoto position), and (ii) a plurality of intermediate zoom positions. The zoom lens includes at least a first movable lens group and a second movable lens group. These first and second lens group are separated from one another by a variable distance. The first and second movable lens groups move (i) together, at the same speed and direction in order to focus at one of the extreme zoom positions and at an adjacent intermediate zoom position; and (ii) differentially in order to focus at another one of the extreme zoom positions.

    摘要: The first, movable encloses the front, middle and rear lens groups. The front and rear lens groups are supported by a front and a rear lens cell, respectively. At least one of the front and rear lens cells is an integral part of the front lens barrel. The front and rear lens cells are located at a fixed distance with respect to one another. The middle lens group is supported by a mid-lens cell. The mid-lens cell is slidably movable within the first, movable barrel and has at least three external cam followers. The second, movable barrel engages and at least partially encloses the first barrel and includes three cam grooves engaging the cam followers. The motor is operatively connected to the second, movable barrel. The motor rotates the second, movable, so that the second, movable barrel moves along the optical axis with respect to the first, movable barrel. The rotation of the second movable barrel causes the cam followers to move within the cam grooves such that the mid-lens group moves axially at a different rate than the front and rear lens groups.

    摘要: A photofinishing device for handling different format types of photographic film includes a work station with a film interface for photofinishing a respective format type of photographic film. The photofinishing device is provided With a first film deck interface utilized for containing a first format type of photographic film at the work station so that the first format type of photographic film may be photofinished while it is maintained in a specified orientation relative to the work station. The first film deck interface is releasably secured to the work station and replaceable with a second film deck interface capable of containing a second format type of photographic film at the work station. In this manner, when the photographic film in the device is changed from the first format type to the second format, the film decks may be quickly changed so that the second format type of photographic film is maintained in a specified orientation relative to work station for photofinishing.

    摘要: An aperture mechanism for controlling the aperture of an optical system includes a flexible diaphragm having an opening at its center for forming a first aperture value for the optical system and means for stretching the diaphragm to enlarge the opening and form at least one additional aperture value for the optical system. A stepper motor is used to stretch the diaphragm to form a plurality of aperture values for the optical system. Because the size of the aperture is determined by how much the diaphragm is stretched, the backlash between the stepper motor and related gearing is kept to a minimum due to the elastic properties of the diaphragm, which provides economical and accurate control of very small apertures.
