    摘要: To allow printing of a sheet of paper large in size without increasing the entire apparatus length and high precision and high speed printing, a sheet-fed duplex printer comprises a pair of impression cylinders (6a,6b) each provided on a peripheral surface thereof with a paper gripper for gripping a sheet of paper, one of the impression cylinders in rotational contact with the other impression cylinder disposed downstream in a direction of rotation of and obliquely below the one impression cylinder. The two impression cylinders are synchronously rotated so that the regions of rotational contact thereof both move downwards. The sheet of paper reversing its printing face when the sheet of paper conveyed following a peripheral surface of the one impression cylinder is conveyed to follow that of the other impression cylinder. A first electrophotographic printing unit (7a) is disposed opposite to a peripheral surface area of the one impression cylinder which area is upstream in the direction of rotation of the one impression cylinder from the region of rotational contact (B) between the one and the other impression cylinder for printing on one face of the sheet of paper being conveyed following the peripheral surface of the one impression cylinder. A second electrophotographic printing unit (7b) is disposed opposite to a peripheral surface area of the other impression cylinder which area is downstream in the direction of rotation of the other impression cylinder from the region of rotational contact between the one and the other impression cylinder for printing on the other face of the sheet of paper being conveyed following the peripheral surface of the other impression cylinder.

    摘要: To allow shortening the horizontal length for sheet-fed duplex printing while preventing a printing face of the sheet of paper printed on upstream in its conveyance direction from becoming soiled by toner transferred from a printing face of sheet of paper printed on downstream in its conveyance direction, a sheet-fed duplex printer comprises a pair of impression cylinders 6a, 6b each provided on a peripheral surface thereof with a paper gripper for gripping a sheet of paper, one of the impression cylinders in rotational contact with the other impression cylinder disposed downstream in a direction of rotation of and obliquely below the one impression cylinder. The two impression cylinders are synchronously rotated so that the regions of rotational contact thereof both move downwards. The sheet of paper reversing its printing face when the sheet of paper conveyed following a peripheral surface of the one impression cylinder is conveyed to follow that of the other impression cylinder. A first electrophotographic printing unit 7a is disposed opposite to a peripheral surface area of the one impression cylinder which area is upstream in the direction of rotation of the one impression cylinder from the region of rotational contact between the one and the other impression cylinder for printing on one face of the sheet of paper being conveyed following the peripheral surface of the one impression cylinder. A second electrophotographic printing unit 7b is disposed opposite to a peripheral surface area of the other impression cylinder which area is downstream in the direction of rotation of the other impression cylinder from the region of rotational contact between the one and the other impression cylinder for printing on the other face of the sheet of paper being conveyed following the peripheral surface of the other impression cylinder. And, a cleaning unit 23 for impression cylinder is disposed opposite to, and adapted to clean, a peripheral surface area of the other impression cylinder, the peripheral surface area of the other impression cylinder being downstream in the direction of its rotation from a position thereon at which the sheet of paper conveyed following the surface of the other -impression cylinder is transferred therefrom downstream in the direction of conveyance of the sheet of paper.

    摘要: It is made possible to non-mechanically adjust and eliminate a mutual deviation between images printed by a plurality of printing units in a digital sheet-fed printing machine using a plurality of transport cylinders.
    A digital sheet-fed printing method is disclosed which comprises: providing one cycle of printing to print on a series of sheets of paper whose number is equal to the least common multiple of respective numbers of allocated positions on adjacent ones of the transport cylinders; for each sheet of paper in the series to be printed in the one cycle of printing, producing a reference signal on the basis of which an image in each color is printed on the sheet of paper with each printing unit, timed to its passage through the printing unit, under control by a printing control means; in a first of such cycles of printing, detecting with an image detection sensor means a mutual out of register between images in different colors printed on each sheet of paper in the series, furnishing the printing control means with a detection signal for each sheet of paper from the image detection sensor means, and correcting the timing at which each image is printed on each sheet of paper in one cycle of printing by the printing control means and on the basis of such detection signals so that timings to print the images in different colors on each sheet of paper may be coincided with one another; and in each subsequent printing cycle, printing images in the different colors on each sheet of paper at a printing timing as corrected as aforesaid.
