PURPOSE:To effectively make plural plates from a manuscript by one-time operation by a method in which a manuscript is scanned, a time-series picture information is obtained and at the same time the first plate is made, the information is once stored in a memory, and the information is read out to perform the plate making operation after the second time at least one-time or more. CONSTITUTION:A manuscript is wound around the front half part of a manuscript cylinder 2, and a stencil paper is wound around the whole surface of a plate cylinder 4. A switch 16 is switched to the fixed contact 16b side and turned on. Main scanning is made by a rotary drum 1 at a fixed speed, and the manuscript 2 is read out by a reading device 8. A picture information is supplied through an input amplifier 9, a mixing circuit 10 and an output amplifier 11 to a recorder 12 for recording the front half part of the stencil paper 4 and at the same time writing is made in the memory circuit 15 through the input amplifier 9 and a comparator 13. The rotary drum 1 is turned to nearly half, a given primary picture region is ended, a timing signal S4 for reading is given from a control signal generation circuit 19, and stored information is orderly read out from the beginning by the clock signal S3. A large number of mineographic plates can thus be obtained from a manuscript by only one-time operation. |
