  • Patent number: 8616671
    Abstract: A multi-channel image is printed on a web receiver by a plurality of printing modules. The receiver is entrained around a take-up roll on a movable transport. During printing, the transport moves past the printing modules while the take-up roll holds the receiver in position with respect to the transport, and then the transport comes to a stop and the take-up roll draws the receiver across the transport. A cutter downstream of the take-up roll cuts off the printed portion of the web receiver to provide a printed sheet.
    Type: Grant

  • Patent number: 5937220
    Abstract: A camera metering mechanism discriminates between 1) adjacent perforations in a set, which trigger said metering mechanism to interrupt the film advance, and 2) adjacent perforations between sets, which do not trigger the interruption. The mechanism uses a difference in spacing between the perforations, which alternates between a first distance within a set and a second longer distance between sets. The mechanism is triggered to interrupt film advance when the space between detected perforations is less than a predetermined distance. If the space exceeds the predetermined distance, then film advance continues until the next successive perforation. According to more specific features, the perforation detector initiates electrical transitions at the leading and trailing edges of the perforations, and film distances are a determined from the time difference between selected transitions.

  • Patent number: 5926664
    Abstract: An electromagnetic actuator includes a core made of a soft magnetic material, a permanent magnet located between a pair of ends of the core, the permanent magnet being supported for movement, and an electrically conductive coil wrapped about a portion of the core. The reluctance of the core is adjustable to alter movement of the permanent magnet as a function of time upon application of electrical current to the coil of the electromagnetic actuator.

  • Patent number: 5835810
    Abstract: Apparatus for automatically moving a film cartridge completely into a cartridge loading chamber includes means for automatically sensing that the cartridge has been partially inserted into the chamber and means for automatically moving the film cartridge fully into the cartridge chamber upon the sensing means sensing that the cartridge has been partially inserted into the chamber.

  • Patent number: 5729773
    Abstract: A camera comprising an optical viewfinder with a pair of aligned front and rear lenses for viewing a subject to be photographed, and a multi-lamp flash wheel rotatable to move respective one-time-use flash lamps to a use position for illuminating the subject, is characterized in that the multi-lamp flash wheel has a lamp cover wheel which is transparent to transmit the illumination from each of the flash lamps in the use position, and the front lens is an integral centered portion of the lamp cover wheel.

  • Patent number: 5697003
    Abstract: A camera comprising a light sensitive film on which a certain number of exposures can be made, and a multi-lamp flash source having a plurality of one-time-use flash lamps equal in number to the total number of exposures to be made on the film, is characterized in that the multi-lamp flash source has consecutive indicators proximate the respective lamps for indicating the number of exposures available to be made and is supported for movement to move the respective lamps from a storage to a use position for illuminating a subject to be photographed and, substantially simultaneously, to move the respective indicators from a concealed to a visible position.
