Abstract: A method for determining a mismatch involving the availability of a dye donor supply and a dye receiver supply in a thermal printer when a particular print size and print quantity are selected, comprises: comparing a remaining number of similar-size donor patches available on the dye donor supply with a remaining number of like-size donor patches required for the selected print size and print quantity, and should the former number be less than the latter number providing a warning; and comparing a remaining length of dye receiver available on the dye receiver supply with a remaining length of dye receiver required for the selected print size and print quantity, and should the former length be less than the latter length providing a warning.
Abstract: In a dye transfer printer, a donor web having successive dye transfer areas that are used for printing and opposite longitudinal edge areas alongside each one of the dye transfer areas that are not used for printing are wrapped under longitudinal tension about a cylindrical spool core. The dye transfer areas that are wrapped under tension about the spool core are stretched thinner than the two edge areas that are wrapped under tension about the spool core due to their being heated during printing. The spool core is depressible inward at respective portions on which the two edge areas are wrapped under tension and is not depressible at an intermediate portion between the depressible portions on which the thinner transfer areas are wrapped under tension. As a result, a convolution build-up of the edge areas on the spool core will be no more than a convolution build-up of the thinner transfer areas on the spool core.
Abstract: A donor web having successive dye transfer areas and opposite longitudinal edge areas alongside each one of the dye transfer areas is subjected to a longitudinal tension when the donor web is advanced in a dye transfer printer, which can stretch the dye transfer areas more than the edge areas because the dye transfer areas, but not the edge areas, are heated at a print head in the printer. According to the invention, the edge areas are pre-weakened before the donor web is used in the printer to weaken a resistance of the edge areas, relative to the dye transfer areas, to being stretched so that the edge areas can be stretched substantially the same as the dye transfer areas when the donor web is used in the printer. The edge areas can be pre-weakened, for example, by perforating or piercing them to create holes in them, or by slitting or cutting them to create cuts in them.
Abstract: In a printing liquid droplet ejector, a liquid holding unit in a cavity has a volume sufficient to hold some of the printing liquid in the cavity and is mechanically translatable toward an opening in a nozzle. The liquid holding unit is volumetrically alterable to reduce its volume to cause at least some of the printing liquid held by the unit to be expelled from the unit, to in turn cause either printing liquid expelled from the unit or other printing liquid in the cavity to be ejected from the opening as at least one droplet, when the unit is mechanically translated toward the opening.
Abstract: A thermal printer is adapted to prevent crease formation in a dye transfer area of a dye donor web that can cause line artifacts to be printed on a dye receiver during a dye transfer from the dye transfer area to the dye receiver in a dye transfer printer.
Abstract: A fitting is attached to a disposable ink supply bag and has an ink egress snout for discharging an ink supply from the bag. The fitting is configured to engage with a housing for the bag to permit the bag to be connected to the housing when the ink supply is to be discharged from the snout and to disengage from the housing to permit the bag to be disconnected from the housing in order to dispose of the bag when emptied.

Abstract: A dye transfer printer uses a dye donor web that is capable of developing a crease-causing wave-like or ripple distortion across the donor web when the donor web is subjected to a longitudinal tension as it is advanced from a print head, over a web guide, and onto a web take-up spool in the printer. The web guide is positioned to extend across the donor web and is adapted to be bowed to effect a curvature across the donor web in proportion to the longitudinal web tension in order to urge the donor web to spread substantially widthwise to reduce the likelihood of the wave-like or ripple distortion developing across the donor web. If the wave-like or ripple distortion is prevented from developing in a dye transfer area being used, it is unlikely that any creases will be created in the next unused transfer area. Thus, no line artifacts will be printed on a dye receiver during dye transfer in the printer.
Abstract: A printer includes a print head for printing from a donor medium to a receiver medium, a platen member for holding the donor medium in a printing relation with the receiver medium at said print head, a pair of steering and drive rollers for feeding the receiver medium from between the steering and drive rollers, and a movable support for the platen member and the steering roller that moves the platen member towards the print head to hold the receiver medium in the printing relation with the donor medium and away from the print head to release the receiver medium from the printing relation with the donor medium and that moves the steering roller to vary a feeding angle at which the receiver medium is fed from between the steering and driver rollers.
Abstract: A compact camera comprises: a main body part having a front and a rear, including upper and lower longitudinally-horizontal partially-cylindrical portions defining rearwardly-open film chambers for a film supply spool and a film cartridge, and another portion between the upper and lower portions defining a rearwardly-open film exposing chamber between the film chambers, to allow a filmstrip to be advanced vertically across the film exposing chamber from one of the film chambers to the other film chamber; a flash circuit board on the front of the main body part, including a flash emission lens at the upper portion; and front and rear cover parts housing the main body part and flash circuit board.
Abstract: An ink cartridge includes a housing with an integral pocket, an ink supply bag contained in the housing, and a memory chip supported in a wall opening of the pocket. The housing has an ink blocking shield arranged at a location between the bag and the memory chip to prevent any ink that might leak from the bag from entering the wall opening and contaminating the memory chip.
Abstract: A camera is capable of being assembled with an alternately positioned mode indicator. The camera includes the following in order to achieve this objective. A support adapted to hold a mode indicator at any one of at least two different locations in order to enable the mode indicator to be alternatively positioned at the respective locations. A part having separate openings aligned with the respective locations at which the mode indicator can be alternatively positioned. And a cover covering each of the openings in the part except the opening aligned with the location at which the mode indicator is positioned, to allow the mode indicator to be sensed via that opening.
Abstract: An ink cartridge includes an ink supply bag, a fitting attached to the bag and including an integral ink egress snout, and a pair of housing halves that contain the bag and at respective wall portions have opening halves that form a bottom opening for the snout when the housing halves are connected together. The fitting and only one of the wall portions each have mutually engageable members that engage to connect the fitting and the one wall portion to secure the bag within the housing half that includes the one wall portion. The housing half that includes another of the wall portions has stakes that are adhered to the engageable members of the fitting and/or the engageable members of the housing half that includes the one wall portion.

Abstract: An ink cartridge includes a flexible bag filled with a liquid ink, and a cartridge housing that holds the bag. The bag is filled to a predetermined percentage of its full volume to fill the bag to less than its capacity in order to prevent the bag from rupturing, but is filled sufficiently to substantially occupy the housing when folded. Preferably, the bag has a width that is greater than a width of the housing and has a length that is less than a length of the housing so that the bag need only be folded widthwise to fit in the housing.
Abstract: A disposable ink assemblage intended for an ink cartridge includes an ink bag containing an ink supply, and an ink egress snout attached to the bag and from which the ink supply is to be discharged from the bag. The snout is configured to be received in a collar only when the collar is in any one of a number of allowable orientations, and to fix the collar relative to the snout in a selected one of the orientations in order that the fixed orientation of the collar may serve to identify the ink supply in the bag.
Abstract: A camera includes a frame counter having a single numerical scale of frame count indicia capable of being successively viewed after each picture is taken. The frame count indicia are arranged in one column in which the indicia are only odd numbers and are arranged in another column in which the indicia are only even numbers. An indicia viewing change-over is movable from one column to another after each picture is taken, to alternately view an odd number in one column or an even number in another column.
Abstract: An ink cartridge includes an ink egress snout from which an ink supply is discharged from the ink cartridge, and a collar that mates with the snout and can be arranged in any one of a number of allowable orientations to provide an identification of the ink supply. The snout and the collar are mutually configured to permit the collar to mate with the snout only when the collar is in any one of the orientations, whereby an identification of the ink supply can be provided simply by the collar mating with the snout.
Abstract: A camera has a wide-angle taking lens and a telephoto taking lens for forming simultaneous wide-angle and telephoto images of the same subject, to make wide-angle and telephoto simultaneous exposures on a single frame of film. A wide-angle/telephoto selection indicator is supported for movement between the taking lenses and the frame of film to prevent either the wide-angle or telephoto image from being fully exposed on the frame of film. Thus, one of the simultaneous exposures is provided with an indication that it is not to be printed as a picture.
Abstract: A thermal printer is adapted to prevent crease formation in a dye transfer area of a dye donor web that can cause line artifacts to be printed on a dye receiver during a dye transfer from the dye transfer area to the dye receiver in a dye transfer printer.
