摘要： A sheet feeder for use with a stack having plates and sheets alternating. Sheets are removed by being reliably suction adhered with a sucker. The sheet feeder includes a suction device, and the sucker and device are mounted at a supporting portion. In order to allow suction adhering of the plates and sheets alternately stacked in a magazine, the suction device is operated when the sucker is brought into contact with the sheet, and the sheet is raised separately from the plate. Thereafter, the sheet is suction adhered to the sucker by suction. This makes it possible to prevent the sucker from suction adhering to the plate together with the sheet, and only the sheet is reliably removed from the stack.

摘要： A belt transmission mechanism has a crowned drive pulley, a crowned driven pulley, and a belt trained under tension around the crowned drive pulley and the crowned driven pulley. The crowned drive pulley and the crowned driven pulley are dimensioned to satisfy the equation:D2/D1=k.multidot.R1/R2where D1 is the diameter of the crowned drive pulley, D2 is the diameter of the crowned driven pulley, R1 is the radius of the crown of the crowned drive pulley, R2 is the radius of the crown of the crowned driven pulley, and k is a constant which is approximately 1. The belt transmission mechanism with the above drive and driven pulley dimensions can maintain its speed reduction ratio highly accurately even when the tension of the belt varies.

摘要： During an initial setting period, if there is a tendency for a belt to move sideways due to tolerance when components are assembled in the initial setting, inclination in the axial direction of a driven roller can be changed after the components are assembled, to adjust degree of tension at both end portions in the transverse direction of the belt wound at a driven roller. Accordingly, the tendency for the belt to move sideways caused during assembly of the components can be corrected. Further, when there are changes over time (reduced elasticity of the belt, changes in the positioned state of rollers, or the like), sideways movement may occur during operation. However, in these cases, since a tapered auxiliary roller is attached at each of end portions in the axial direction of the rollers so as to be able to rotate relatively to the respective roller that is the base body thereof, when the belt moves sideways onto the auxiliary rollers the belt can be promptly returned to its original position.

摘要： A color conversion module 42 carries out color conversion of original color image data Grgb from the RGB color system into the CMYK color system to obtain color-converted original color image data Gcmyk (step S104). A DCT module 44 applies DCT (discrete cosine transform) over the whole color-converted original color image data Gcmyk to generate DCT coefficients Dcmyk (step S106). An embedding module 46 embeds the watermark information s into the components C, M, Y, and K of the DCT coefficients Dcmyk (step S108). An IDCT module 48 applies IDCT (inverse discrete cosine transform) onto DCT coefficients D′cmyk with the watermark information s embedded therein to generate embedding-processed color image data G′cmyk (step S110). The color conversion module 42 carries out color conversion of the embedding-processed color image data G′cmyk from the CMYK color system into the RGB color system to obtain embedding-processed color image data G′rgb (step S112). This arrangement does not require any correction of the position or the shape of image blocks in the process of extracting the embedded watermark information.

摘要： A device for selecting and conveying printing plates is provided which can overcome complexity of work involved in so-called batch processing, and can realize operation of, for example, removing a printing plate from a cassette in a small space, such that operation efficiency can be improved and less space is required. Cassettes other than a lowest cassette are independently supported on sliding bases. The sliding bases move (slide) on rails with hardly any frictional resistance. The rails extend to a cassette withdrawing space section provided adjacent, and unnecessary cassettes are moved horizontally along the rails. Thus, a printing plate can be removed from a needed cassette at a reference position without the needed cassette being moved at all. In this way, there is no need to provide, at each cassette, space for removing the printing plate, and no need to move a printing plate removing device to positions at which the cassettes are disposed.

摘要： A device for removing an image recording material is provided, which takes up little space and is used with printing plates and interleaf sheets set alternately in a cassette. An interleaf sheet and a printing plate are taken out simultaneously. In the midst of being conveyed along a conveying path leading to an exposure section, only the interleaf sheet is sucked by a fan or drawn-in between a roller pair so as to be peeled off from the printing plate. The peeled-off interleaf sheet is discarded, and the printing plate is conveyed reliably to the exposure section.

摘要： A sheet feeding method for plate-shaped members is disclosed. In a sucker unit, suction nozzles are move down from respective original positions toward a bottom plate of a cassette at a fixed speed, and time t1 until the bottom plate is detected by a contact sensor, and an amount by which the suction nozzles move, &Dgr;y, until the suction nozzles suction adhere to the bottom plate after the bottom plate is detected by the contact sensor are measured. Subsequently, separation positions of the suction nozzles with respect to the original positions are set based on an interval between the bottom plate of the cassette and separation plates, and an interval required by the photopolymer plate being bent between the suction nozzles and the separation plates at an appropriate curvature. Based on the result of the setting, the photopolymer plate is reliably taken out from the cassette.

摘要： A suction transport device capable of reducing manufacturing cost due to reduction of the number of suction mechanisms by which one of photopolymer plates accommodated in a magazine is taken out is attained. Also separability when the printing plate is taken out is improved, thus improving reliability of the suction transport device. Since, among suckers and suction fans, those located at positions corresponding to the widthwise direction ends of the printing plates are movable in the widthwise direction, and separating plates are movable in the same direction. When one of the printing plates of a different size is to be taken out, the leading end corner portions of the printing plate can always be curved at a fixed curvature, and separability is improved. Further, there is no need to increase the number of suckers thus decreasing cost.

摘要： An image recording material separating/removing device which, by using a single lift-out mechanism section, can lift image recording materials out from plural cassettes along simple loci of movement, and in which a space for providing and withdrawing the cassettes is kept as small as possible. In a cassette housing section, a plurality of cassettes are disposed one above another. Each cassette is offset in a horizontal direction. An amount of offset is set on the basis of a locus of movement of a printing plate at a time when the printing plate is sucked and held by suction cups and lifted up in a vertical direction. At least while the suction cups are moving in the vertical direction, the printing plate is not interfered with by cassettes thereabove, and an emulsion surface of the printing plate is not scratched. Space required for placement of the cassette housing section can be reduced. Moreover, because movement of the suction cups can be simplified, a control system can be simplified.
