摘要： A recyclable single-use camera in which a front casing portion is separable from a main body portion to replace a taking lens during recycling of said camera, is characterized in that the taking lens has a front lens element and a rear lens element. The rear lens element is secured to the main body portion in order to prevent removal of the rear lens element. The front casing portion holds the front lens element in optical alignment with the rear lens element, and permits removal of the front lens element to allow it to be replaced whenever the front casing portion is separated from the main body portion during recycling of the camera.

摘要： A lens system is provided. The lens system includes a first lens system moveable between a first position removed from an optical axis and a second position on the optical axis. The first lens system includes a first lens element, an aperture stop, and a second lens element positioned in order from an object side to an image side of the lens system. The first lens system has a first focal length. A second lens system is moveable between a first position on the optical axis and a second position removed from the optical axis. The second lens system has a second focal length with the second focal length being greater than the first focal length such that a magnification ratio change results from interchanging the first lens system and the second system on the optical axis.

摘要： A water-resistant camera comprising a frame counter having successive numbered portions for indicating the particular number of exposures remaining for picture-taking, and an optical magnifier for transmitting ambient light beams to the frame counter to form an enlarged image of any one of the numbered portions in order to facilitate viewing the one numbered portion, is characterized in that the optical magnifier is positioned out of optical alignment with at the one numbered portion, and includes an optical wedge that bends the light beams the optical magnifier transmits to the frame counter in order to make the enlarged image of the one numbered portion appear to be optically aligned with the optical magnifier.

摘要： A compact Galilean-type zoom finder suitable for compact cameras, and the like whose zoom ratio is about 2. The zoom finder is comprised of four units having negative, negative, positive and negative refractive powers in order from an object side and a movable framing window. The first and the fourth lens units are fixed and the second and the third lens units are moved to perform zooming. The moving framing window helps to delineate the field of view.

摘要： A two position variable focal length lens is provided. The variable focal length lens includes a common lens element moveably positioned on an optical axis; a wide angle lens element moveable between a first location removed from the optical axis and a first position on the optical axis on an image side of the common lens element; and a telephoto lens element moveable between a second location removed from the optical axis and a second position on the optical axis on the image side of the common lens element. A magnification ratio change is effected by moving the common lens element along the optical axis and switching between the wide angle lens element located at the first position on the optical axis and the telephoto lens element located at the second position on the optical axis.
