摘要:
A printer is capable of simply carrying out image division printing (repeat printing), and capable of reducing the number of images that are unusable due to clipping of the image on the leading edge of the sheet. The printer has an image division printing function of forming a plurality of print images on a single sheet, and comprises: an image reading unit that reads document images; a plate making unit that makes master plates; a printing unit having a cylinder around which a master made in the plate making unit is wound, and a pressure member that presses sheets against the cylinder; and a sheet supply unit that supplies sheets to the printing unit. The printer also comprises an image size input device for inputting the length of the document image in the main scanning direction and the sub scanning direction; and a sheet size detection device for detecting the size of the sheets, and when using the image division printing function, the print images corresponding to the document images formed on the sheet are arranged by being rotated through 180 degrees, based on the image size input by the image size input device and the detection results of the sheet size detection device.

An offset lithographic duplicating machine is adapted to reproduce master plates having markings on marginal areas indicative of the number of copies to be made therefrom. A photoelectric reading device reads the markings as a master plate enters the machine from a storage area and sends signals to a memory device which records the number of copies indicated. A counter records the copies completed and the master plate is ejected from the machine when the full number is completed. A master plate feed mechanism then feeds a succeeding master plate from the storage area and the process is repeated.
