摘要:
A display, a signage system including the display, and methods of writing the display, are described, wherein the system includes at least one display, at least one writing unit, and at least one holder. Each display includes at least one bi-stable display element and at least one electrical interconnect substrate. The display can be written using the writing unit and displayed in the writing unit or in the holder.

A printhead includes a plurality of nozzle arrays disposed on a substrate. Each nozzle array is positioned on the substrate to eject droplets of a liquid spaced apart from each other on a receiver. Each nozzle array is positioned relative to other nozzle arrays such that liquid ejected from the plurality of nozzle arrays is sufficient to cover a surface of the receiver in a single relative motion of the printhead and the receiver.

A camera door actuated cartridge extractor includes a rod which is pivotally mounted to the cartridge chamber closing camera door at a point between the camera door pivot and the adjacent wall of the cartridge chamber so that initial opening of the camera door provides a relatively large extracting motion that quickly disconnects the cartridge from the driver. Thus, manual movement of the driver by the camera operator is less likely to move film within the cartridge after a film enclosing cartridge door is closed. A spring may be provided biasing the camera door to a partially open position to accelerate disconnection of the cartridge from the driver. Placement of the extractor rod in a slot between adjacent battery pockets provides a compact arrangement. Engagement of a hook-like keeper portion of the extractor rod with a rib on the door provides a friction force for maintaining the door in a fully open position until closing is desired.

An apparatus for securing a thrust film cartridge and for moving a film door between open and closed positions. The apparatus includes a camera body adapted to receive a thrust film cartridge, a camera door interconnectable with the camera body, and an actuating device. The actuating device includes a latch member, a lug member operatively associated with the latch member, a handle member operatively associated with the latch member, and a force limiting mechanism for limiting the force which can be applied by the handle member on the latch member. The latch member is movable between a locked position, to lock the camera door in the closed position, and an unlocked position, to allow the camera door to move between the open and closed positions. The lug member is engageable with a film door of a thrust film cartridge to move the film door between open and closed positions. The handle member is movable by a user of the apparatus to provide an unlocking force to the latch member and to move the latch member from the locked position to the unlocked position.

A scanning thermal dye printer has a plurality of linear scanning arrays positioned to sequentially scan selective color information from a source image and produce a color plane using the selective color information, and a plurality of thermal dye transfer stations, each thermal dye transfer station being responsive to information from a selected one of the linear scanning arrays. The printer includes means for advancing the source image between successive linear scanning arrays, and means for advancing a dye receiving member between successive dye transfer stations. There is at least one roller having a circumference and being disposed between adjacent dye transfer stations in guiding contact with the dye receiving member, and means for changing the position of the roller and adjusting the position of one color plane relative to another color plane.

A compact camera comprising a body housing, a film roll chamber within the body housing, and a flip-up flash pivotally connected to the body housing to permit the flip-up flash to be flipped up from the body housing for use and flipped down to the body housing for storage, is characterized in that the body housing has a protruding portion that at least partially forms the film roll chamber, and the flip-up flash has a flash housing with a cavity for receiving the protruding portion when the flip-up flash is flipped down to the body housing, to integrate the flash housing with the body housing.

A photographic camera for making pseudo photographs on film exposure areas upon opening of a camera shutter includes a light emitting diode disposed in the camera body for directly illuminating one or more positions on the film, an aperture disposed in the camera body between the light emitting diode and film for controlling illumination of the light emitting diode to provide a predetermined coded pattern of exposure on one or more positions of the film, and a lever positionable between the aperture and film to cover or uncover the aperture to regulate film exposure by the light passing through the aperture upon camera shutter opening.

A camera to be used with a cartridge enclosing a spool mounting a filmstrip having an access door for opening and closing the camera includes an interlock mechanism connected to the access door and engageable with the spool for preventing the access door from being opened when the spool indicates an unexposed position of the filmstrip.
