Embodiment Construction
[0043] figure 1 It is a side view schematically showing the stencil printing machine of the embodiment of the present invention. The stencil printing machine takes the device body 9 as the main structure, and the device body 9 includes: an image reading device 8, a plate making device 11, a printing device 12, a plate supply device 13, a paper supply device 15, a paper discharge device 16, a typesetting device 17, etc. . The image reading device 8 reads an image of a document placed on the document table to generate image data. The plate making device 11 pulls out the roll-shaped stencil base paper 10, heats and perforates the plate according to the image data of the original document, and performs plate making. The plate supply device 13 supplies the stencil base paper 10 for which plate making has been completed to the printing device 12 . The paper feeding device 15 conveys the printing paper 14 to the printing device 12 . The paper discharge device 15 discharges the pr...

The present invention provides a platemaking device of a stencil printer, which can properly perform the cutting of stencil base paper by a cutting tool and the transfer of the stencil base paper by a transfer roller, by preventing a wrinkle and a sag in the stencil base paper. This platemaking device of the stencil printer performs platemaking by recording image information in the stencil base paper 10 through a heating perforation process, transfers the stencil base paper 10 after the platemaking to the printer 12 by means of the transfer roller 58, and cuts the stencil base paper 10 to a predetermined length by means of the cutting tool 77. The platemaking device is equipped with a transfer path surface 57 for forming a transfer path for the stencil base paper 10. In the platemaking device, at least two transfer rollers 58 for transferring the stencil base paper 10 in the state of sandwiching it between the transfer path surface 57 and the transfer rollers 58 are provided at an interval in a base-paper transfer direction. The cutting tool 77 is provided between the two transfer rollers 58F and 58R, and a suction unit 75 for making the stencil base paper 10 sucked in to the transfer path surface 57 is provided on an upstream side in the base-paper transfer direction with respect to the cutting tool 7 between the two transfer rollers 58F and 58R.
Description
(1) Technical field [0001] The invention relates to a plate making device of a stencil printing machine. (2) Background technology [0002] Generally speaking, the working principle of a stencil printing machine is as follows: the stencil base paper (master plate) wound into a roll is pulled out, and the image information obtained by the image reading device is heated and perforated on the stencil base paper by a thermal head. For plate making, the stencil base paper after plate making is conveyed by conveying rollers, cut into a predetermined length by a cutting tool, and the cut stencil base paper is supplied to the printing device for printing. [0003] As one of such stencil printing machines, Patent Document 1 discloses the following structure: in the conveying path leading to the printing device, there are in order from the upstream side of the conveying direction to the downstream side: a thermal head and a platen roller. Heated perforation section, upper and lower p...
