Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stencil printing device with a plate making device, and more particularly to a stencil printing device with a plate making device having an automatic plate discharging mechanism.

[0002]

2. Description of the Related Art A document image reading means such as an image scanner for reading a document image on a document sheet and an automatic document feeding means (auto document feeder, hereinafter referred to as ADF) for feeding the document image to the document image reading means one by one. The stencil sheet to which the original image read by the original image reading means is applied to the stencil sheet, the stencil sheet to which the stencil sheet made by the stencil sheet is mounted, and the stencil sheet to be removed from the stencil sheet. A stencil printing machine with a plate-making device having a plate discharge means for feeding a base paper to a plate discharge storage is already known.

In a stencil printing machine with a plate-making device having an ADF, when an operator sets a plurality of original sheets on the ADF and operates a plate-making / print start button on the operation panel, the original sheets are made one by one. Stencil printing that is supplied to the image reading means and uses each manuscript sheet as a manuscript, scans the manuscript image, makes a plate, mounts the stencil sheet on the plate cylinder, peels the used stencil sheet from the plate cylinder, and discharges the stencil sheet. All of the stencil printing using a plurality of original sheets is automatically performed based on a series of sequence operations of feeding to the storage section.

[0006] The plate discharge accommodating portion is usually composed of a replaceable bag body and box body, and there is a maximum value in the number of stencil sheets that can be accommodated due to their internal volume.

If the stencil sheet is discharged in excess of the maximum number of stencil sheets that can be stored in the stencil sheet storage section, problems such as clogging of the stencil sheet will occur during the stencil sheet ejection process. It is necessary to detect that the number of stored sheets has been reached.

In view of this, data of the number of stencil sheets that can be stored in the stencil sheet storage unit is acquired in advance by an experiment or the like, and the number of stencil sheet stencil sheets is counted every time the stencil sheet discharging process is performed, and the count value is the maximum number of stored sheets. If the count value reaches the maximum number of sheets that can be stored, the next plate discharge process and plate making process are prohibited, and the plate discharge storage section becomes full on the operation panel display etc. It has been proposed to incorporate a safety device, which displays a message, and inputs a confirmation signal for removing the stencil sheet from the stencil storage unit, into the stencil printing machine with a stencil making device to release the prohibition of the stencil discharge process and the plate making process.

[0007]

However, in the above-mentioned safety device, the plate discharge process, the plate-making process are prohibited, and a message indicating that is displayed only when the plate discharge storage section is full. The following problems occur when stencil printing is performed using a plurality of original sheets when used.

When performing stencil printing with a plurality of original sheets, the operator simply sets the plurality of original sheets on the ADF by effectively utilizing the above-described automatic processing function of the stencil printer with a plate making device. However, by operating the plate making / printing start button on the operation panel, the operator often leaves the device.

On the other hand, before the plate making / printing process of each original sheet is performed, the stencil sheet used for the previous printing is always discharged and sent to the discharged plate storing section, and the ADF
If the number of stencil sheets stored in the stencil storage section reaches the maximum number before the plate making / printing is completed for all the original sheets set in, the safety device operates and the plate making / printing process stops. After operating the plate making / printing start button on the operation panel, if the operator immediately leaves the machine, the machine will be left in a stopped state and the operator will return to the machine because all stencil printing has been completed. In some cases, the stencil printing using only some original sheets may be completed and the work may be interrupted on the way against the intention of the operator.

In this case, the operator has to discard the stencil sheet in the plate discharge storage portion, and then again operate the plate making / printing start button to wait until the plate making / printing of the last original sheet is completed. . This causes the printing schedule of the user to be disordered, which in turn causes a reduction in the operating efficiency of the stencil printing machine with a plate making machine.

The present invention has been made in view of the above problems, and in the plate making / printing of a plurality of original sheets using the ADF, there is a possibility that the work is interrupted during the plate making / printing process. This is to make the operator aware at the beginning of the work, and to prevent the work from being interrupted during the plate making / printing process, and avoiding leaving the device in a work stopped state during the work. An object is to provide a stencil printer with a device.

FIG. 3 shows an embodiment of a control system of a stencil printing machine with a plate making device. This control system has a CPU 111 composed of a microprocessor or the like, a ROM 113 storing a control program, and a RAM 115 for storing input information and the like at any time, and has an operation panel 97, a pressure plate side document set sensor 34, an ADF document set. Sensor 4
5, plate discharge sensor 93, plate discharge box set switch 9
5, various sensors (not shown) provided in other parts, and signals output from switches are input and the control program is executed to execute the document reading unit 11, the automatic document feeder 13, the plate making unit 15, the printing unit 17, and the feeding unit. The paper unit 19, the paper discharge unit 21, and the plate discharge unit 23 are collectively controlled to read a document, make a plate,
Executes printing and plate ejection operations.

When the pressure plate side original set sensor 34 or the ADF original set sensor 45 is in the ON state, the CPU 111 automatically sets the plate making mode, and thereafter, the number of sheets to be printed is set by the ten keys 99, and the start key 105 is set.
When is pressed, a series of plate-making printing processing is executed. On the other hand, when both of the document set sensors 34 and 45 are in the OFF state, the print mode is automatically set, and thereafter the ten keys 99 are used. When the number of prints is set and the start key 105 is pressed, the printing process is executed.

When the ADF original document setting sensor 45 outputs an ON signal, that is, when it is detected that the original document sheet is set on the original document setting tray 35, the line image sensor 27 causes the target glass plate 33 to operate on the target glass plate 33 by an operation command from the CPU 111. To a position C immediately below, and the original image of the sheet original can be read by using the ADF 13, and the ADF 13 starts the automatic original feeding operation by the plate-making printing start command by pressing the start key 105.
By supplying the original sheet onto the target glass plate 33, the original image is read by the line image sensor 27 in the original scanning movement type.

On the other hand, the pressure plate side document set sensor 34
Outputs an ON signal, that is, when it is detected that an original is set on the original placing glass table 100, the plate-making printing start command is output by pressing the start key 105, whereby the line image sensor 27 Scans and moves between the home position A and the scan end position B at a predetermined speed, and the reading of the original image of the original set on the original placing glass table 100 is performed by the sensor scanning movement method.

When the reading of the original image is started as described above, the heat sensitive stencil sheet M is fed by the platen roller 51 and the raw paper feed roller 53, and the writing according to the original image read by the line image sensor 27 is performed. In this case, the perforation plate making is performed on the heat-sensitive stencil sheet M by the thermal head 49.

Prior to the above-described original image reading operation and plate making operation, a plate discharging process for removing the used stencil sheet M, which has been used for the printing process and wound around the outer peripheral surface of the plate cylinder 63, is carried out. Must be done.

This plate discharge processing releases the clamp of the stencil sheet M by the sheet clamping unit 62 on the plate cylinder 63,
The plate cylinder 63 is rotated in the counterclockwise direction in the figure around its own center axis, and in the course of this rotation, the leading edge of the stencil sheet M is hooked by the plate discharge separation claw 87 to move the stencil sheet M to the plate cylinder 6.
The stencil sheet M is peeled off from No. 3 and fed into the plate discharge box 89 by the plate discharge roller 92.

Each time the plate discharge process is performed, the plate discharge sensor 93 detects the passage of the used stencil sheet M fed into the plate discharge box 89 by the plate discharge roller 92, and outputs a detection signal to the CPU 111.

The CPU 111 includes counting means for counting the detection signal input from the plate discharge sensor 93 as the number of stencil sheets M sent to the plate discharge box 89, and the count value n is stored in the RAM 115. RAM
The count value n stored in 115 is set in the plate discharge box 91 by turning on and off the plate discharge box set switch 95.
Is removed from the plate discharge box support 91, and when it is detected again that the plate has been set on the plate discharge box support 91, the initial value “0” is cleared.

Therefore, unless the plate discharge box 89 is removed from the plate discharge box support 91, the count value n stored in the RAM 115 is incremented each time the plate discharge sensor 93 detects the passage of the stencil sheet M.

The RAM 115 is used as a work area for the CPU 111, and the print setting number data,
The maximum number of sheets (full data) Nmax of the stencil sheet M that can be stored in the plate discharge box 89, for example, "100", and a storage unit full advance notice value Npre that is smaller than the maximum number of sheets Nmax by a predetermined amount Nset, for example, a predetermined amount Nset = "20". "
"80" is stored in advance as a maximum storage number setting means and a storage section full advance value setting means. The maximum number Nmax of sheets to be stored is determined by the size (internal volume) of the plate discharge box 89, and the predetermined amount Nset may be set according to the maximum number of originals set in the ADF 13.

The CPU 111 starts the first comparing means for comparing the storage unit full advance notice value Npre with the count value n only when the ADF document setting sensor 45 detects that the document sheet is set on the ADF 13. When the key 105 is turned on by a pressing operation, it constitutes a second comparing means for always comparing the maximum number Nmax of stored sheets with the count value n, and the comparison result by the first comparing means is
When the count value n ≧ the storage unit full advance notice value Nprer, the next plate discharge operation is input by the user confirmation signal. In this case, the start key 105 is prohibited until it is pressed again, and the second comparison means is used. The comparison result is the count value n
= When the maximum number of stored sheets is Nmax, a stencil sheet removal confirmation signal is input for the next plate discharging operation overcoming the comparison result by the first comparing means. In this case, the plate discharging box set switch 95 is turned on from the off state. The control is forcibly prohibited until it is detected that the plate discharge box 89 is set again on the plate discharge box support 91.

Here, even if the determination of the comparison result by the first comparing means is the count value n> the storage unit full advance notice value Nprer, the determination of the comparison result by the second comparing means is the count value n ≧ maximum storage. It goes without saying that the number may be Nmax.

The storage unit full advance notice value Npre preset in the RAM 115 is set in the ADF 13 when a large number of original sheets are sequentially read using the ADF 13 to perform printing processing of each original sheet. Before the printing of all the original sheets is completed, the plate discharge box 89 is filled with the stencil sheet M stored therein, that is, the comparison result by the second comparing means becomes the count value n = the maximum number of stored sheets Nmax, In order to prevent the plate making / printing process from being interrupted, a number smaller than the full number of the plate discharge box 89 is set in advance as a reference value, which is set according to the maximum number of originals set in the ADF 13 as described above. Just do it.

In the CPU 111, the comparison result by the first comparing means is the count value n ≧ the storage unit full advance notice value Nprer.
, The stencil sheet M in the plate discharge box 89
In order to notify the user that the number of stored sheets is close to the maximum stored number Nmax, a message display is instructed by the display 107, and the comparison result by the second comparison means is the count value n.
= When the maximum number of stored sheets is Nmax, the number of stored stencil sheets M in the plate discharge box 89 is the maximum number of stored sheets Nm
In order to notify the user that the ax has been reached, the display 107
Command the message display by. FIG. 2A shows an example of the message display when the count value n ≧ the storage unit full advance notice value Nprer, and the count value n = the maximum number of stored sheets Nmax.
An example of the message display in the case of is shown in FIG.

FIG. 4 shows an operation flow of plate making / printing processing by this apparatus.

The original sheet to be printed is set on the original set tray 35 of the ADF 13 or the original placing glass table 29, the number of sheets to be printed is set by the ten key 99 of the operation panel 97, and the start key 105 is set by the operator.
When is turned on (step 10), it is first determined whether or not the ADF original document setting sensor 45 is turned on (step 20).

When the ADF document set sensor 45 is on, the count value n, which is the plate discharge count data, is compared with the storage unit full advance notice value Nprer (step 30).

Count value n ≧ storage unit full advance notice value Npre
If not r, that is, the stencil sheet M in the plate discharge box 89
If the number of stored sheets has not reached the number of storage unit full notice, the plate discharge process is executed (step 40), and the count value n is incremented by 1 in accordance with the execution of the plate discharge process (step 50). Next, a series of processes of reading the original image, plate-making, mounting the plate-made stencil sheet M on the plate cylinder 63, and printing are executed (step 60).

On the other hand, if the determination result in step 30 is the count value n ≧ the storage unit full advance notice value Nprer, then the count value n is compared with the maximum storage number Nmax (step 70). If the count value n is not equal to the maximum number of stored sheets Nmax, that is, if the number of stored stencil sheets M in the plate discharge box 89 has reached the storage unit full notice number, but has not reached the maximum stored number, the plate discharge process is performed. Is prohibited (step 80), and as shown in FIG. 2 (a), a plate discharge full notice is displayed (step 90).

Next, it is judged that the plate discharge box 89 has been removed and that the plate discharge box 89 has been set again by the state change of the plate discharge box set switch 95 (change from the off state to the on state) (step 100). If it is detected, the count value n is cleared (step 110).

After that, when the start key 105 is turned on as a user confirmation operation, the process proceeds to step 40 regardless of the state change of the plate discharge box set switch 95, and the number of stencil sheets M stored in the plate discharge box 89 is full. Similar to the case where the number of noticed sheets has not been reached, the plate discharge process is executed (step 40), and the count value n is incremented by 1 in accordance with the execution of the plate discharge process (step 5).
0) Next, a series of processes of reading an original image, making a plate, attaching the plate-made stencil sheet M to the plate cylinder 63, and printing are executed (step 60).

On the other hand, when the result of the determination in step 70 is the count value n = the maximum number of stored sheets Nmax,
The plate discharge processing is prohibited (step 130), and as shown in FIG. 2B, the plate discharge full display is performed (step 140).

At this time, the plate discharge box 89 is removed and the plate discharge box 89 is set again by monitoring the state change of the plate discharge box set switch 95 (change from OFF state to ON state) (step 150). If this is detected, the count value n is cleared (step 160), and it is monitored that the start key 105 is turned on (step 170).

When the start key 105 is turned on, the process proceeds to step 40, where the plate is discharged, the count value n is counted up, the original image is read, the plate is made, and the stencil sheet M is made.
A series of processes for mounting and printing on the plate cylinder 63 are executed (steps 40, 50, 60).

When the printing of the predetermined number of sheets is completed, it is judged whether or not the ADF document set sensor 45 is turned off (step 180). ADF original set sensor 45
If is OFF, the routine ends assuming that printing of all original sheets is completed. On the other hand, if the ADF original set sensor 45 is not OFF, it is determined that there are still original sheets in the original set tray 135 of the ADF 13. In order to prepare for the next plate making / printing, the process proceeds to step 190, and thereafter, every time when a new original sheet is made, the judgment of the count value n = the maximum number of stored sheets Nmax is performed, and the count value n <the maximum number of stored sheets Nmax, Plate making / printing is continued only when the plate can be discharged.

If it is detected that the pressure plate side original set sensor 34 is turned on when the original is set on the original placing glass table 29 when the ADF 13 is not used (step 200), the count in step 30 is performed. The determination of the value n ≧ the storage unit full advance notice value Nprer is not executed, and the process proceeds to step 190, where the count value n = the maximum storage number Nmax.
Is determined. Count value n <maximum number of stored sheets Nma
If x, the process proceeds to step 40 and plate making / printing is executed.

If both the ADF original set sensor 45 and the pressure plate side original set sensor 34 are off, the plate making process is not performed and the printing process for the number of prints set as the print mode is executed (step 210). .

In the above-described embodiment, the plate discharge operation is prohibited until the user confirmation signal is input when the count value n ≧ the storage unit full advance notice value Nprer, but this plate discharge operation is prohibited. May be released only for a predetermined time and released without the need to input a user confirmation signal.

[0065]

As can be understood from the above description, according to the stencil printing apparatus with a plate making device of the present invention,
When the DF is used, the storage unit full advance notice value Npre is compared with the count value n counted by the counting means, and the comparison result is count value n ≧ storage unit full advance notice value N.
If it is prer, the next plate discharging operation by the plate discharging means is prohibited until, for example, a user confirmation signal is input, and a message indicating this is displayed. Therefore, the operator can print the stencil sheet in the plate discharging storage section (plate discharging box). When the number of stored sheets is close to the maximum number of stored sheets Nmax and the number of stored stencil sheets in the plate discharge storage section reaches the maximum number of stored sheets Nmax, there is a possibility that the work may be interrupted during the plate making / printing process. It is possible to know in advance when work is started. As a result, when the operator starts the work, such as discarding the stencil document in the stencil box, the work is interrupted during the plate making / printing process, and the device is stopped during the work. It is avoided to be left unattended.

When the count value n is compared with the maximum number Nmax of stored sheets by the second comparing means and the comparison result is the count value n = the maximum number Nmax of stored sheets, the plate discharge processing failure due to the excessive plate discharge occurs. In order to avoid the occurrence, the next plate ejection operation by the plate ejection means exceeds the comparison result by the first comparison means until the stencil document in the plate ejection box is discarded and the plate ejection box is reset. It is banned and the occurrence of troubles due to over-printing is avoided.
