Abstract: A contact printer for printing negatives in rows and columns directly onto photographic paper comprises a flat smooth base plate having a pair of upstanding pins adjacent one side edge. The pins are mounted in slots so as to be adjustable longitudinally of the side edge both in spacing and in distance from the bottom edge. The negatives are placed in rows and columns within an archival preserver sleeve which has holes along one side edge engaged over the pins to locate the sleeve and therefore the negatives on the base plate. Photographic paper is inserted under the sleeve and is located on the base plate by engagement with the pins and by alignment of the bottom edge of the paper with the bottom edge of the base plate. This ensures that the negatives are properly aligned with the paper. A transparent cover plate is also provided to press the negatives onto the paper for exposure of the paper by light directed through the transparent cover plate.

Abstract: In a rear-projection screen comprising a Fresnel lens and a light-diffusing member containing light-diffusing fine particles, it is intended to decrease the moire and to give no dark feeling at the border even when projection systems are set in a short projection distance. For this end, in the rear-projection screen of the present invention, the thickness of the light-diffusing member is made larger at the border than at the center of the rear-projection screen, or the concentration of the light-diffusing fine particles contained in the light-diffusing member is made larger at the border than at the center so that the rear-projection screen can have light diffusion properties greater at its border than at its center. Here, any of a flat plate, a flat sheet and a lenticular lens sheet can be used as the light-diffusing member.

The pellicle includes a pellicle membrane mounted to a pellicle frame by a first adhesive layer and with the pellicle frame being mounted to the photomask by a second adhesive layer. The protective mask is fabricated of an opaque material and is positioned between the light source and the two adhesive layers to shield them from the light source.

Abstract: A light source having a solid state laser emitting a beam that is separated into a number of segments. Each segment is frequency shifted by a different amount so that the segments do not substantially overlap in the frequency domain. Each segment passes through a short focal length lens element of a fly's eye array to be dispersed onto a mask plane for evenly illuminating a mask. The lens elements of the fly's eye array are contained within a small region in comparison to the width of the dispersed beam segments, such that each beam segment contributes illumination to the entirety of a common portion of the mask.

The projection units are provided respectively for the exposing positions of the transport members.

Abstract: An imaging system is disclosed which incorporates a gradient index lens array to transmit focused light onto an image medium with increased Depth of Focus (DOF) and no loss of radiometric efficiency. The lens array is first constructed so that its exit pupil is generally symmetrical. This first step increases the radiometric efficiency of the lens array relative to prior art lens arrays. In a second step, the DOF is increased by reducing a quantity n.sub.o .sqroot.AR which is associated with the lens, n.sub.o being the axial refractive index of the fibers comprising the lens array, .sqroot.A being the gradient index constant of the material comprising the lens array and R being the radius of the individual optical rods, As this quantity is reduced, the DOF increases consistent with a trade off of reduced radiometric efficiency. Since the efficiency was initially increased from some optimum value, the DOF can be increased until the desired radiometric efficiency level is reached.

Abstract: Tractor drives of a high speed printer move a length of continuous-form paper longitudinally up from a box of fanfold stacked paper, through a print mechanism, across paper directing means, and downward to refold onto a fanfold stack. A misfold detector is positioned at the paper directing means to sense the jumble of paper caused by misfolding prior to jamming of paper movement through the tractor drive to prevent damage to the paper, complex restarting procedures, or data loss.

Abstract: A longitudinal-stripe lenticular lens screen and a transverse-stripe lenticular lens screen are superposed, and a light diffusing agent is mixed only in the longitudinal-stripe lenticular lens screen. Therefore, the light transmittance is high although the angle of view can be three-dimensionally widened by the two lenticular lens screens. In addition, since scan lines of an image are blurred by two diffusion planes, Moire becomes inconspicuous.

Abstract: An apparatus for arraying sheets of photosensitive material provided in a film printing/developing apparatus. A sorting guide is provided for selectively feeding the sheets of photosensitive material according to their size. The sorted sheets are fed further either in a one-line arrangement or in a two-line zigzag arrangement to an upper outlet or to a lower outlet by guides. Along the path to the lower outlet are mounted one-way rollers and high-speed rollers, so that the sheets of photosensitive material in a two-line zigzag arrangement will be fed at high speed. The sheets of photosensitive material thus fed out of the lower outlet are overlapped one upon another on the pan by means of a conveyor in the order of the frames in one roll of film.

Abstract: A paper mask device in which the position of longitudinal masks can be changed without damaging a web of printing paper. When it is changed from the borderless printing to the printing with border, one ends of the longitudinal masks are moved inwardly toward each other by means of a first transfer unit while keeping the other ends overlapped on the edges of the printing paper. A second transfer unit then operates to move the other ends of the longitudinal masks inwardly to set the width of the print size. The longitudinal masks can be overlapped on both edges of the printing paper without damaging it.
