Abstract

PURPOSE:To improve the printing efficiency, and at the same time, reduce noise by feeding a plurality of printing papers to one sheet of stencil base paper when printing is performed on small sized printing papers. CONSTITUTION:In a paper feed cassette 7a on the upper stage, printing papers 6 of A4 size are loaded/stored with the longer edge to be rectangular to the feeding direction (lateral feeding), and in a paper feed cassette 7c on the lower stage, printing papers 6 of A3 size are loaded/stored with the longer edge to be in parallel with the feeding direction (longitudinal feeding). Characters/image on a manuscript are read by a line sensor 49 and a plate is made on a stencil base paper 17 by a thermal head 19 or second thermal head 28, or transferred to a heat-sensitive printing paper 59. Since a plate cylinder 3 has a size to be able to cope with even when the printing papers 6 of A3 size are longitudinally fed, when the printing papers 6 of A4 size are laterally fed, two surfaces of plate can be made on one sheet of the stencil base paper 17, and by one rotation of the plate cylinder 3, two sheets of the same printed matters can be obtained.

DETAILED DESCRIPTION OF THE INVENTION (a) Industrial Application Field The present invention relates to a stencil printing apparatus in which at least two sheets of manuscript are made on one sheet of stencil paper, and two sheets of paper can be continuously fed. It is something.

(b) Conventional technology It is not necessary to give specific examples in the conventional stencil printing device.
A manuscript for one sheet of printing paper is made into one sheet of stencil paper, and 1
One sheet of stencil paper corresponds to one sheet of printing paper.

The applicant of the present application has already proposed a stencil printing apparatus in which stencil sheets on which a plurality of manuscripts have been made can be wrapped around one plate cylinder (see Japanese Patent Application No. 1-66885). However, this stencil printing apparatus is intended for multicolor printing, and as a general rule, a plurality of completely identical originals are not made into plates for -sheets of originals.

(C) Problems to be Solved by the Invention As mentioned above, in the conventional technology, one sheet of manuscript is made on one sheet of stencil paper, and one sheet of stencil paper and one sheet of printing paper correspond to each other. Because of this, the printing speed was proportional to the number of rotations of the plate cylinder and was limited.

Therefore, as a matter of course, the higher the printing speed is, the more noise there is likely to be.

The present invention has been made in view of the problems of the conventional technology, and can increase the printing speed without increasing the number of rotations of the plate cylinder, and can also be used when there is no need to increase the printing speed. The object of the present invention is to realize a stencil printing device that can reduce noise.

The present invention also aims to realize a stencil printing device that can print on printing paper having an area equivalent to two pages (for example, an original document having an area equivalent to two A4 size pages and an A3 size printing paper) if necessary. .

(e) Effect In the first main invention, the printing paper is fed vertically in the first printing mode, that is, in a posture in which the long side of the printing paper is parallel to the feeding direction, and the printing paper is fed in the second printing mode. In the mode, the printing paper is fed horizontally, that is, with the long side of the printing paper perpendicular to the feeding direction.

In the second main invention, in the first printing mode, one sheet of printing paper is fed and pressed against one sheet of stencil paper to perform a single printing operation. In the second printing mode, a plurality of printing sheets are continuously or intermittently fed and pressed against one stencil sheet, and a plurality of printing operations are sequentially executed. That is, in the first print mode, one sheet is printed while the plate cylinder rotates once, and in the second print mode, a plurality of sheets are printed while the plate cylinder rotates once.

In the third main invention, the paper feeding roller is controlled so that in a specific printing mode, the rotation start timing of the paper feeding roller is different between odd-numbered sheets and even-numbered sheets of printing paper to be fed. That is, the distance between the printing paper and the other printing paper will be different before and after the printing paper during its transport path.

The image is made into a stencil sheet 17 by the thermal head 28 or printed onto a thermal printing paper 59.

Next, according to FIGS. 7 to 9, the register roller pair 12 is
．． The rotation start timing of 13 and the printing position with respect to the plate cylinder 3 and stencil paper 17 will be explained.

As mentioned above, in this embodiment, the A4 size printing paper 6 is fed horizontally, but the stencil paper 17 and the plate cylinder 3 are fed horizontally.
It has a size that can accommodate the case where A3 size printing paper 6 is fed vertically, so when A4 size printing paper 6 is fed horizontally, two sides can be made on one stencil sheet 17. This makes it possible to obtain two identical printed materials by rotating the plate cylinder 3 once.

In addition, when each printing paper 6 is fed vertically, FIG. 8(A)
When the printing paper 6 of A4 size is fed horizontally, the plate is made as shown in FIG. 8(B).

As is clear from these figures, in the case of vertical feeding, the downstream edges of each printing paper 6 are aligned, and in the case of horizontal feeding of A4 size printing paper 6, the downstream edges touch the stencil paper 17. The downstream end of the odd numbered sheets coincides with the downstream end of each of the printing sheets 6, but the downstream end of the even numbered sheets that contact the stencil paper 17 is different from the downstream end of each of the printing sheets 6. It does not match.

Therefore, the rotation start timing of the pair of register rollers 12 and 13 is as shown by the Δ mark in FIG. The odd numbered sheets of B4 size printing paper 6 when feeding vertically and the lengthwise feeding of A3 size printing paper 6 match, but the even numbered sheets of A4 size printing paper 6 when feeding horizontally match the above. It does not match the case of .

Also, when A4 size printing paper 6 is fed horizontally,
A non-printing area of the plate cylinder 3 (the area indicated by angle a in FIG. 7),
The non-plate-making areas (areas indicated by angle β in FIG. 7) of the same two sides of the stencil paper 17 are different, and a>
A relationship β holds true. Therefore, register roller pair 12
．． 13, in a specific printing mode, that is, in the horizontal feeding mode for A4 size printing paper 6, the rotation start timing is different for odd-numbered sheets and even-numbered sheets of printing paper 8, and the rotation start operation is different. It will increase once.

Therefore, during the transport path of the printing paper 6, the distance (corresponding to β) between the downstream edge of the odd-numbered printing paper 6 and the upstream edge of the even-numbered printing paper 6 is The distance between the downstream edge of the printing paper 6 and the upstream edge of the odd-numbered printing paper 6 (corresponding to a) is smaller than the distance (corresponding to a).

In this embodiment, the plate-making unit M is constructed so that it can be pulled out to the operation side together with the spare paper mounting table 30, but it is also possible to configure so that only the plate-making unit M can be separately pulled out to the operation side. It is possible.

Further, FIG. 6 is a perspective view of an embodiment in which the document reading device 48 is not installed, and as is clear from this figure, since no paper feeding section or paper ejection section protrudes from the left and right sides of the main body of the device, It is possible to place OA type equipment tables closely on the left and right sides of the device body, and it is also possible to input document images by connecting to a word processor or personal computer online.

(g) Effects of the invention In the first and second main inventions, when printing on small-sized printing paper, multiple sheets of printing paper are fed to one stencil sheet, and the same plate cylinder is used. Printing speed increases even when rotating at rotational speed. Therefore, printing efficiency is improved.

Furthermore, if the printing speed is kept the same as before, the rotational speed of the plate cylinder will be halved and noise will also be reduced. Therefore, even if the apparatus of the present invention is installed in a shooting office, the user will not be bothered by noise.

In the third main invention, the paper feeding roller is controlled so that its rotation start timing is different for the odd-numbered and even-numbered sheets of printing paper being fed in a specific printing mode.
Even if there is a slightly wide non-printing area on the printing cylinder, a plurality of printing sheets can be accurately pressed against one stencil sheet.
