摘要： A display processor of a controller extracts data such as images and characters from display data stored in a storage based on setting information stored in the storage, and displays a document orientation instructing pane and a 90-degree rotation operation icon in a document image operating pane on a display device. The display processor also displays a print preview image based on the document image data. When a rotation operation is performed through the 90-degree rotation operation icon, the document image data is also subjected to the same rotation process.

摘要： An image forming apparatus includes a main assembly and a unit detachably mountable to the main assembly. The main assembly includes a positioning portion. The unit includes a portion-to-be-positioned engaging with the positioning portion and a grip portion configured to be gripped by a user when the unit is demounted from the main assembly. The main assembly further includes an inclined surface provided immediately in front of the positioning portion with respect to a mounting direction of the unit to the main assembly and configured to guide the portion-to-be-positioned to the positioning portion. The grip portion includes a grip surface configured to receive a force exerted in a pulling-out direction of the unit by the user when the user pulls out the unit from the main assembly. The grip surface and the inclined surface form an angle of substantially not less than 90°.

摘要： There are provided an image reading device and a printing apparatus that can reduce an influence of the shadows of suction holes. Suction holes, which are used to suck a sheet, are arranged on the peripheral surface of a drum that transports the sheet. The suction holes are arranged in grooves that are formed along a direction orthogonal to a transport direction. Accordingly, since an influence of the shadows of the suction holes can be reduced even in a case in which density unevenness is inspected on the basis of a read image, the false detection of density unevenness can be prevented.

摘要： An assembly for transferring information to and/or from flexible sheet media in a highly advantageous curved configuration is disclosed. The sheet material includes a length and a width defining first and second opposing surfaces. The assembly includes support means for supporting the sheet the curved configuration across its width, having the first surface inwardly oriented with respect to the curved configuration. Thereafter, moving means moves the flexible sheet material so supported in a direction along a read/write path generally parallel to the sheet material length and transverse to the direction of curvature. A read/write arrangement is provided which is configured for reading and/or writing information across the width of the first surface of the sheet as the sheet is moved along the path in the curved configuration. In one feature, means is provided for rotationally moving the read/write arrangement in a predetermined way in the housing such that the read/write arrangement is in a confronting relationship with the first, inwardly oriented surface and cooperates with the movement provided by the sheet material moving means so as to cause the read/write arrangement to sequentially read information from and/or write information to the inwardly oriented, first surface of the sheet as the read/write arrangement traverses the width of the flexible sheet material while the latter is on the read/write path in the curved configuration. In another feature, a read and/or write operation may be performed on the second, outwardly oriented surface of the sheet material.

摘要： A printing plate is only guided by and wound around peripheral surfaces of cylinders. The cylinders are disposed along an axis of a rotating shaft at predetermined intervals, and support the entire printing plate with substantially equal balance. The printing plate has a degree of firmness, and thus, the printing plate can hold itself in a substantially cylindrical shape even if it is merely rolled in the air. Therefore, the whole printing plate can be accurately wound and held onto a peripheral locus of a predetermined radius coaxial with the rotating shaft merely by disposing guide members as auxiliary guides for positioning and winding parts of the printing plate.

摘要： A sheet member holding apparatus which holds a winding direction end portion of a sheet member that is wound around a rotary body. Centrifugal force generated by rotation of the rotary body is efficiently utilized to hold the end portion securely and prevent looseness or the like of the sheet member, because the holding apparatus is designed such that the expression {(μ1+μ2)×(L2/L1)×m}>c×r×t is satisfied. L1 is distance from a fulcrum to a clamp section, L2 is distance from the fulcrum to a center of gravity, m is mass of a plate of the apparatus per unit length in the rotary body's axial direction, t is thickness and c is density of the sheet member, and μ1 and μ2 are coefficients of friction between the sheet member and, respectively, the clamp section and the rotary body.
