As explained above, the printing device 1 in this embodiment is
After wrapping the stencil paper S around the outer circumferential surface of the plate cylinder 20 and applying ink to the stencil paper S, the printing paper P is wrapped around the outer circumferential surface of the plate cylinder 20 (overlaid on the stencil paper) and printed by pressing. Each mechanism is controlled by a microcomputer.

Next, the automatic printing system @1oo which is the main part of the present invention
(Reading means) will be explained.

As shown in FIGS. 2 and 3, an automatic printing device 100
is the optical sensor 101. A stencil sheet set plate 102, a plate feeding roller 104. Sakahandaki pad 105° optical reader 10
It is mainly composed of a microcomputer to which outputs from the optical sensor 101 and the optical sensor 101 are transmitted and which controls the entire printing apparatus. ;1・1'.

,,□ ・ The optical sensor-01 is a known light reflection type object detector, and detects the presence or absence of the stencil sheet S (whether or not it is set on the set plate 10□゛2), and The output, 1-force is the information on the control operation of the microcombi 1-Y.
Ru.

,' □ The stencil sheet setting plate 102 is a plate-shaped body for setting the stencil sheet S at a predetermined position, and is rotatably attached to a pivot shaft 102a whose upper end is fixed to a machine frame (not shown). Further, on the lower surface of the set plate 102, there are fixed plates 1,
03, and between the set plate 102 and the fixing plate 103, suitable spring members 10, 1, 1, 2, 1, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, 2, etc. , and 8 are provided, so that the set plate 102 is kept in constant contact with the roller 04 by the spring material 108.
is energized by

At one end of this fixing plate 103, there is a small cylindrical projection 103A.
is provided in a protruding manner, and when the set plate 102 is rotated to overlap with the fixed plate 103 (indicated by a dotted line in the figure), the tip of the small protrusion 103A is formed to penetrate corresponding to the small protrusion 103A. The bond passing through the opening 102A of the set plate 102 is designed to protrude from the surface of the set plate 102 by an appropriate length.

Therefore, the hole rFL is formed at the projecting end of this small protrusion 103A.
By simply engaging the positioning holes of the base paper S, the stencil paper can be accurately set on the setting plate 02.

Also, after setting the stencil paper S as described above.

Since the setting plate 102 is pressed against the roller 104 by the return force of the spring member 108, there is no misalignment of the stencil sheet S, and it is convenient for the stencil sheet S to be conveyed by the rollers 104.

The plate feeding roller 104 is a cylindrical body made of rubber or the like, and has a shaft 104a integrated with the roller 104 at its center, and this shaft 104a is connected to a power transmission mechanism consisting of a motor (not shown) or the like. .

Therefore, by rotating the roller 04 clockwise in the figure, the stencil sheet S can be conveyed to a position where one edge thereof can be clamped by the clamp mechanism 21.

The plate handling support member 105 works together with the plate feeding roller 04,
When a plurality of stencil sheets S are set, this is to take them out one by one starting from the highest one, and this stencil handling support member 105 has a relatively high resistance material such as rubber in the contact portion with the roller 04. A paper sorting pad 105a made of □ material is provided □
It has a separating plate 105A, and has a cylindrical foot 105B on the opposite side from the roller 04.
The leg 105B is the hole 20 drilled in the machine frame 200.
It is slidably inserted into the 0a□ peephole;・;1・;. In addition, a coil spring 1□05c is loosely fitted to the outer periphery of the leg 105B,・ゝ)゛,“ along its length.
□ One end is supported on the back surface of the handling plate 105A, and the other end is supported on the surface of the machine frame 200.

Therefore, the pad 105 is always urged to come into contact with the roller 04, and can be pushed down to the back of the hole 200a as necessary.

The optical reader 106 is a known device that optically reads print setting information attached to the stencil MS, and its output is transmitted to the microcomputer.

Next, the electrical components of the present invention will be explained according to FIG.

In the figure, a CPLJ 200 composed of a microprocessor, etc. includes a ROM 210 storing programs for controlling each vl@ in the device, an operation panel 5. Read @ @ 106. Optical sensor 1 that detects the presence or absence of stencil paper S
01. An optical sensor 901 detects that the stencil sheet S has been conveyed to a position where it can be clamped.A plate cylinder driving motor 33 constitutes a plate cylinder drive unit that rotates the plate cylinder 20i continuously or in parts. Paper feed roller drive motor 60M, press roller operation motor 40M, plate feed roller drive motor 1
04M, tape sorter 7, clamp m side 21, plate discharge mechanism (stencil paper removal mechanism) 70. and a RAM 220 for temporarily storing calculation results of the microprocessor and the like.

Next, the stencil paper S used in the printing apparatus 1 will be explained.

As shown in FIGS. 5 and 6, the stencil paper S includes a rectangular mount 301 made of a porous material such as Japanese paper, and a rectangular thermoplastic film such as a polyester film having approximately the same size as the mount 301. A base paper main body 302 made of a resin film is pasted together with an adhesive or the like, and a strip-shaped reinforcing paper piece 303 is pasted along the lateral edges of the base paper main body 302.

Generally, the stencil paper S consists of just the base paper body 302 and the reinforcing paper piece 30.
The state consisting of 3 is the state after the perforation of the stencil paper S has been completed and stencil printing is about to be started by a rotary printing machine, etc.; S is generally provided with a mount 1 to facilitate handling and storage of the original paper.

The mount 301 and the base paper main body 302 are adhered to each other by adhesives 304 and 305 at the top and bottom over the entire width in the transverse direction, and the upper part of the reinforcing paper piece 303 is attached to the mount 3 by an adhesive 304.
01 and the intermediate portion is attached to the base paper main body 302 with an adhesive 306.

Further, a positioning hole 307 is formed through the upper part of the stencil paper S to engage with the small protrusion 103A when setting the stencil paper.

Note that since the mount 301 is to be removed during printing, the lower part 305a attached to the base paper main body 302 is removably attached, and perforations 308 are formed at predetermined locations on the upper part for easy separation. ing.

As described above, since the base paper main body 302 is in the form of an extremely thin film, the mount 301 supports it from one side during plate making or during handling before and after plate making.

This is the base paper main body 302 (so-called printing '7)''''' star 5 (already printed stencil paper), and constitutes the main body of the stencil paper S in this embodiment.

On the surface of the reinforcing paper piece 303, there are print number setting sections SA, 3B, and SC for setting the number of print sheets corresponding to each master.
, SD, and a printing speed setting section SS. In this embodiment, the number of printed sheets and printing speed are print setting information, and are configured to be optically readable using a mark sheet method.
6 may use another reading device, such as a device that can read Arabic numerals or a device that can be mechanically read by perforation. Of course, we must give.

Furthermore, the place where the print setting information is attached does not necessarily need to be provided on the reinforcing paper piece 303 as described above, but a piece of paper for attaching the print setting information is attached to the rear end of the stencil paper S or on both sides of the stencil paper S. Of course, it is good to do so. In this case, printing using these stencil sheets S will not affect the printed matter.

Next, the overall operation of the device 1 of the present invention will be explained according to the flowchart shown in FIG.

Set an appropriate number of stencil sheets S on the set plate 102,
When you press the start button (step 100 ON constant), C
Based on the command signal from the PU200, the clamp mechanism 2

) Next, the clamp machine @21 is set to the clamp standby position, and the plate feeding roller 104 is driven.

The plate feeding roller 104 cooperates with the plate separation pad 105a to sequentially take out the stencil sheets S from the top and convey them to the clamp mechanism 21 (step 1200). Note that while the stencil paper S is conveyed on the conveyance path 107, it passes directly under the optical reading device @106, so the print setting information of the reinforcing paper piece 303 mentioned above is read (step 130).
0), this information is stored in the storage area of RAM 220.

The reinforcing paper piece 303 of the stencil paper S is clamped by the clamp machine @2...:
When it reaches 1, the optical sensor 90 detects that fact.
00, and the CPU 200 clamps the reinforcing paper piece 30 of the stencil paper S based on this transmission signal.
A command signal is issued to hold 3. In this state, the stencil paper S is clamped at one edge, and the glue 6
The part facing the lamped part,
□), : Across its entire width, it is held between the plate feeding roller 04 and the plate handling pads 105a1□i, . A certain amount of tension is applied to the stencil paper S. Therefore, when the plate cylinder 20 is rotated counterclockwise in the figure, the stencil paper S is subjected to a certain amount of tension. In the given state, the outer periphery of the plate cylinder 20 も; can be prevented.

8. When the stencil paper S is wrapped around the plate cylinder 20G-'', the plate cylinder 20 rotates one more time at a low speed.At this time, the feed/paper machine groove 60, the ink supply roller 36, etc. are operated, and one trial sheet is made. Printing is done (
Step 1500).

Step 1600) when starting printing work, RAM22
Print setting information SA, SB stored in 0.

Based on sc and so, the CPU 200 controls each mechanism to print a predetermined number of sheets corresponding to the stencil sheet S.

In other words, when each set reaches a predetermined number of prints, Step 1
700 (Yes), it is checked whether printing of all sets has been completed, and if it has not been completed, the tape sorter 7 is driven and a predetermined length of tape is placed on the printed paper (step 2100>, Division is performed.That is, for each set of A, B, C, and D as shown in Fig. 5,
41 pieces.

In the case of printing only 45, 42, or 47 sheets, when a predetermined number of sheets for group A are printed (Yes at step 1700), the tape sorter 7 places a predetermined length of paper tape on top of the printed sheets of group A. (Step 1800 negative, Step 2100>) Next, eight sets of print setting information are read and the CPU 200 is controlled (Step 2200
).

In this way, when printing from A to D is completed (step 18001), a paper tape of a predetermined length is placed on the tape sorter 7, and the optical sensor 0゛]1,
14') Next 0 stencil paper St'1"'"1'LTC+"j
When c+'c" is detected (step 2000, negative), the gold seal "'" printing operation is completed.

□゛・]・ □゛□ On the other hand, due to optical sensor-01,
When it is detected that the next stencil paper is set (Step Near 20
00 affirmative), return to step 1100, and previous':
The stencil paper used for the previous printing is peeled off in the same manner as described above, and the next printing operation begins.

In addition, as another embodiment in which print setting information is given to the stencil M1S using a mark sheet method, as shown in FIG. 1) when printing only 1 sheet), 2 when printing multiple sets of the same number of sheets on one master (100 sets with 20 sheets as 1 set in the figure), and 7 sets from A to G. For each predetermined number of sheets (in the figure, 20 sheets, 30 sheets, 40 sheets, 50 sheets, 60 sheets, 7 sheets, respectively)
0 sheets, 80 sheets) When printing separately (3), it is very convenient to have a configuration in which each setting field is provided so that settings can be made as necessary.

In addition, an information setting field 303A@ is provided for inputting the same print setting information as the previous one for the next stencil sheet, and in case of 3 above, if the number of sheets is the same as the previous set. Providing a setting field 303B in which the number of sheets can be set by marking only in one place can simplify and speed up the marking work.
