Abstract: In a rear projection screen, a plurality of convex lenses of the prescribed configuration are made of photoresist and formed and arranged on a surface or surfaces of a substrate in the prescribed pattern. In case that the convex lenses are formed in the shapes of ellipsoid, the longer radial direction of the ellipsoid is made to coincide with the horizontal direction and shapes of the lenses are changed gradually from the center of the screen to the extremity thereof. Bottom surfaces of non-lens boundary grooves between adjacent convex lenses are made rougher than the convex lens surfaces. A screen manufacturing method comprises the steps of applying photoresist onto a surface or surfaces of a substrate, exposing a patttern of boundary grooves onto the photoresist by photolithography, forming the boundary grooves by etching, and heating and melting the photoresist which is formed with the boundary grooves so as to form a plurality of convex lenses having the prescribed configuration.

Abstract: An improved camera, and a method of using it, so that a user of the inventive camera may be photographed, together with other objects to be photographed, in a simultaneous manner, without the need for a time delay. The present invention comprises a camera that includes a front primary lens to focus an image of a primary object to be photographed onto a frame of film having a photosensitive emulsion coating a transparent film base. A rear secondary lens focusses an image of the photographer onto a portion of the same film frame through the transparent film base, such that the image exposes the photosensitive emulsion on the front side of the film. A light shield is provided within the camera body to block light from the front primary lens from exposing the portion of the film frame on which light from the rear secondary lens is focussed.

Abstract: An image forming apparatus for forming an image on a pressure-deformable or pressure-damageable image receiving member, such as corrugated cardboard, using a photosensitive, pressure-sensitive recording medium referred to as a microcapsule sheet which has a surface coated with an immense number of microcapsules encapsulating a chromogenic material therein. The microcapsule sheet is exposed to imaging light to form a latent image thereon. A developing agent is deposited on the latent image formed portion of the recording medium and a pressure is applied thereto to develop a visible image. The visible image is formed on the microcapsule or another member. In a thermal transfer section, the imaged microcapsule sheet and the image receiving member which are superposed one on the other are heated to transfer the image onto the surface of the image receiving member.

Abstract: A photographic printer has at least two film carriers which are moved together in a direction perpendicular to a film transporting direction. A photographic film is subjected to light measurement while drawn out from a film cartridge on the first film carrier and, simultaneously, another photographic film is subjected to printing while rewound back into a film cartridge on the second film carrier. The printing is performed according to the result of previously performed light measurement. Upon completion of the printing in the second film carrier, the respective film carriers are moved to change over the operation steps such that the photographic film on the first film carrier is subjected to printing, and that the film cartridge into which the printed photographic film has been rewound is replaced by a new film cartridge on the second film carrier.

Abstract: A reader-printer selectively switchable to a reader mode allowing an image recorded in a microfilm to be projected on a screen and a print mode allowing the image light to be projected on an image-carrying member. This reader-printer is provided with a scanning unit which is selectively movable to a position for projecting the image on the screen and a position for projecting the image on the image-carrying member. This scanning unit in the printer mode causes the image to be projected as rotated 90 degrees on the image-carrying member and allows the image to impinge as though a scanning light on the image-carrying member. As a result, when the image laid widthwise on the screen is printed on the copying paper, this image is projected in a turned posture on the image-carrying member and the copying paper on which the image has been printed is discharged through the front face of the reader-printer.

Abstract: Support means for a workpiece, such as for example a printed circuit board to be screen printed, comprise a plurality of parallel upright elongate members, upper ends of which engage the underside of the workpiece or components secured thereon. Armatures and electromagneto magnets are provided in a housing selectively to clamp the elongate members in a raised position or allow them to fall to a lowered position.Clamping means to clamp the workpiece comprise clamping plates on opposite sides of the workpiece and having very thin foils projecting laterally therefrom over the workpiece and operating means to lower or raise the clamping plates to clamp or release the workpiece.

Abstract: In an auto-printer, wherein original frames to be printed are sequentially and automatically printed at an optimum exposure amount, which is determined based on frame specification data which includes exposure correction data, frame number and position data and stored during negative inspection. The frame position data is compared with an actual amount of film advancement detected when advancing the frame toward a print position, so as to determine whether the frame specification data corresponds to the actual frame placed in the print position. Simultaneously, the actual frame number of the frame placed in the print position is determined based on frame number bar code read from the photographic film during advancing the film, so as to compare the actual frame number with the frame number data.

Abstract: A camera provided with a loading chamber for loading a cartridge housing an image recording medium, a cover member for covering a cartridge loading aperture of the loading chamber, a resilient member for biasing the cartridge loaded in the loading chamber toward the loading aperture, and a support member for supporting the cartridge in the loading chamber against the biasing force of the resilient member and releasing the supporting action, in response to a movement of the cover member in a direction to open the loading aperture.

Abstract: A microfilm viewer/printer projection system particularly adapted for full plane plain paper copying has a first, a second and a third mirror which selectively project a document image from a horizontal object plane to a vertical viewing plane or a horizontal exposure plane. In the view mode, the first and second mirrors reflect the document image to a screen which defines the viewing plane. An AC motor movement drives the first and second mirrors to a print mode, in which the second mirror is parked in a parking zone which is enveloped by the projection path from the object plane to the exposure plane, which is defined by a belt type photoreceptor. In the print mode, the first mirror reflects the entire document image to the third mirror, which is a black mirror, and the third mirror reflects the entire document image to the photoreceptor, to expose the photoreceptor to the entire document image simultaneously.

Abstract: An imaging system in which images are formed by image-wise exposing a layer containing a chromogenic material and a photosensitive composition in which at least the photosensitive composition is encapsulated in a lyer of pressure rupturable capsules. Exposure and capsule rupture renders the chromogenic material image-wise accessible to the developer for a patterned image forming reaction.

Abstract: A reader printer is disclosed which incorporates therein a scanning plane mirror for projecting an image in the form of a slit on a sensitive material. The sensitive material is shifted proportionately to the rotation of the scanning mirror so that the position at which the image is projected on the sensitive material will coincide with the scanning position of the sensitive material. As a result, the otherwise possible phenomenon of defocusing is precluded and the image is faithfully reproduced on a recording paper. The mechanism for rotating the scanning mirror and the mechanism for shifting the sensitive material are divided to allow production of a reader printer of a small size.

Abstract: When a film where a picture image is recorded in a vertical format is used in a reader printer with a horizontal type screen, the image rotating operation as well as the enlarging and reducing operations of the projected image, which should be changed over between the reader mode and the printing mode, may be performed easily through the operation of only one operation member.

Abstract: A film supplying apparatus includes a holding member for holding the vicinity of leading end portions of strips of negative film placed therein in a superposed state with a longitudinal direction of the negative film set in a curved configuration, and a pressing device for pressing an innermost ones, as viewed in a curved state, of the strips of negative film against a feed roller via the holding member. Accordingly, as the feed roller is rotated in the negative film feeding direction, the strips of film starting with the innermost one, as viewed in the curved state, of the strips of negative film are consecutively fed to a printer. In this case, since a force acting in a direction in which the curved shape of the film is reduced is applied to the negative film being fed, no large friction occurs with respect to the remaining film.

Abstract: Light is passed through a negative located in a primary optical path and towards a band of copy material disposed in the path. A reflector is movable into the primary path so as to deflect the light into a secondary optical path. A mat, transparent plate is situated in the secondary path. The plate is situated in a plane which is a conjugate of the plane of the copy material with reference to the reflector when the latter is in the primary path. A sharp image of the negative is formed on the plate. Light passing through the plate is deflected into a tertiary optical path by a second reflector. The light entering the tertiary path is sensed by a video camera which then causes the image on the plate to be reproduced on a monitor for evaluation prior to copying.
