Abstract: In the plate supplying apparatus of the present invention, various vibrations are provided to a plate secured via suction during a separating operation by causing pad rods 403 to repeat a slight ascent and a pause, and thereafter causing the pad rods 403 to make an abrupt descent, thereby reliably peeling off a slip sheet adhering to the back face of the plate. Further, vibration in the rod-up/down direction is provided to the plate during the separating operation, and the plate is not pushed hard. Thus, it is possible to prevent the plate from being damaged. A raising and lowering motor 52 is driven to lower the cassette 9. A separating operation for peeling off a slip sheet S adhering to the back face of the plate P is performed, and thereafter the plate P secured via suction is turned over and transferred.

Abstract: In an optical system, when a binary image is to be read, a first reducing projection lens is located onto an optical axis and focuses an image of the original at a first magnification (relatively high magnification), and a mirror divides the entire image into three divided images which will be then projected onto three CCDs, respectively. On the other hand, when a multivalued image is to be read, a second reducing projection lens is located onto the optical axis and focuses an image of the original at a second magnification (relatively low magnification) which is lower than the first magnification, and the entire image is projected onto one of the three CCDs.

Abstract: The invention provides an apparatus for processing silver salt photosensitive material with a small amount of processing solution. The processing solution uniformly reacts with the photosensitive material for maintaining high processing quality.The apparatus of the invention includes: a process tank 96 which is relatively small in volume; and a developer supply roller 98 which is partly soaked in the processing solution. New or unused developer is temporarily stored in a temporary reservoir 100 formed on the circumference of the roller, held in pores of sponge formed on the surface of the developer supply roller, and supplied to an inlet of photosensitive material PM in the process tank 96 with rotation of the roller 98. The new processing solution is uniformly diffused, along the width of the photosensitive material PM, in the vicinity of the inlet in the stored processing solution. Accordingly, the photosensitive material PM is evenly and efficiently processed.

Abstract: A reproduction magnification of an image to be reproduced is inputted through a inputting device. A projection optical system is adjusted according to the reproduction magnification, and then projects image light reflected from an original in the form of a slit onto a photosensitive material sheet. As projecting the slit image light, the original and the photosensitive material sheet are synchronously fed each other.

Abstract: The slit exposure process camera keeps a photosensitive material flat in the exposure position, and further makes a useless area on the material smaller. The apparatus includes: a pair of feeding rollers 25 disposed upstream from the exposure position for conveying a photosensitive material PM; a transport guide 61 with a flat surface arranged downstream from the rollers 25; and a pressing plate 70 with sufficient elasticity and abrasion resistance for pressing the photosensitive material PM downward. The photosensitive material PM thus pressed runs in contact with a surface of the transport guide 61 and is thereby kept sufficiently flat. Since the process camera does not include another pair of rollers downstream from the exposure position, image reproduction is not disturbed by nipping of the photosensitive material with the downstream rollers, and an unusable area on the end of the photosensitive material is made relatively small.

Abstract: A synchronous driving apparatus for use in a scanning exposure type reproducing apparatus. A scanning system and a recording sheet are moved in synchronization without regard to changes in temperature.

Abstract: A developing apparatus for developing a presensitized plate comprises a developer tank for storing a developer, a feed roller provided at an upper portion of the feeding side of the developer tank for feeding the presensitized plate into the developer tank, a discharging roller provided at an upper portion of the discharging side of the developer tank for discharging the presensitized plate from the developer tank, a feeding belt extending below the feed roller and from the surface of the developer into the developer for guiding the presensitized plate, a pressing roller for pressing the presensitized plate fed by the feed roller onto the conveyor belt, and a guide plate provided between the pressing roller and the discharging roller for guiding the presensitized plate.

Abstract: A multiple-exposure apparatus in a graphic arts copying machine of a slit-exposure type includes an original holding member mounted for horizontal reciprocating motion. An optical exposure system exposes an optical image of a slitwise segment of the original onto a photosensitive material. A moving device reciprocates the holding member and conveys the photosensitive material relative to the optical system. The moving device is adapted to synchronize the advance of the original holding member and the conveyance of the photosensitive material. A data setting device is provided for setting predetermined data concerning a predetermined multiple-exposure layout mode of the original onto the photosensitive material. A control unit controls the operation of the optical exposure system by enabling and disabling the exposure by the optical system and also synchronizes the moving device in an associated relationship as a function of the predetermined set data.
