First, a general operation of the stencil printing apparatus 5 by the control unit 80 will be described, and then a configuration and control for performing a management function unique to the present embodiment will be described.
[0038]
In the stencil printing machine 5, when a stencil making start key on an operation panel (not shown) is operated, the printing drum 20 rotates counterclockwise in a direction opposite to the rotation direction A indicated by an arrow in FIG. The rear end of the used master 28 </ b> B is picked up and separated by a pair of plate discharge rollers (not shown) in the plate discharge unit 40, and is peeled off from the outer peripheral surface of the printing drum 20.
[0039]
In parallel with the plate discharge, the original reading unit 70 reads an image of the original, and converts the electric signal photoelectrically converted by the image sensor (not shown) to an analog / digital (A / D) converter (not shown) in the apparatus main body 5A. It is input and converted to a digital image signal. In parallel with the image reading, a plate making and plate feeding process is performed in the plate making section 30 based on the print data corresponding to the digitized original, and a plate-making master 28A is formed. The leading end of the master 28A is fed toward the outer peripheral side of the printing drum 20, and hangs down toward the expanded clamper 21 (shown by a two-dot chain line) of the printing drum 20 in the plate feeding position state shown in FIG. Then, the leading end of the master 28A is clamped by the clamper 21 at a predetermined timing, and the printing drum 20 rotates in the rotation direction A, so that the master 28A is wound around the outer peripheral surface thereof. Is cut to a predetermined length (length for one plate).
[0040]
When the cut master 28A is wound around the outer peripheral surface of the printing drum 20, the plate making and the plate feeding are completed, and printing is started. First, one of the uppermost sheets of the printing paper P stacked on the paper feed tray 59 is sent out to the registration roller pair 53 by the paper supply roller 51 and the separation roller pair 52, and further sent out by the registration roller pair 53. It is sent to the printing pressure unit 29 at a predetermined timing synchronized with the rotation of the printing drum 20. When the sent printing paper P comes between the printing drum 20 and the press roller 25, the press roller 25 indicated by a solid line in FIG. By being displaced upward as described above, the printing drum 20 is pressed against the master 28A wound on the outer peripheral surface. In this manner, the ink oozes out from the opening portion of the printing drum 20 and the piercing portion (both are not shown) of the master 28A, and the oozing ink is transferred to the surface of the printing paper P to form a print image.
[0041]
At this time, on the inner peripheral side of the printing drum 20, ink is dropped and supplied from an ink supply hole formed in the support shaft 23 to an ink reservoir 27 formed between the ink roller 24 and the doctor roller 26.

[0043]
(Description of configuration related to management function)
As shown in FIG. 4, the stencil printing apparatus 5 has a control unit 80, a print data storage unit 81, a billing information storage unit 82, a counting unit 83, a storage unit 84, and a moving amount of the master 28 A sent out by the stencil making unit 3. , A base paper size storage unit 86, a code input unit 89, an authentication code storage unit 87, and an output unit 90. In the present embodiment, the detection unit 85 detects the number of pulses of the pulse motor 32 from the start of plate making to the end of plate making.
[0044]
The print data storage unit 81 is configured by a RAM that stores the print data B in association with the identification data A. The charging information storage unit 82 stores different charging information according to the base paper size. In the present embodiment, the amount per plate is set according to the JIS standard A3 size and A4 size master. The counting means 83 counts the number of times of plate making and the number of times of printing based on the print data B used for plate making and printing, and the base paper size, that is, accounting information corresponding to the master size for each identification code. The storage unit 84 is a non-volatile RAM, and is a battery backup memory capable of retaining stored data even when the power is turned off. The storage unit 84 stores a billing management table, and count results are stored in the billing management table for each identification code.
[0045]
The base paper size storage unit 86 is configured by a ROM in which the size of the master according to the moving amount is stored in advance. In the present embodiment, the size of the master 28A wound around the print drum 20 is set to the A3 size or the A4 size according to the JIS standard. Therefore, the original size storage unit 86 corresponds to the movement amount corresponding to the A3 size and the A4 size. The number of pulses of the pulse motor 32 is stored.
[0046]
The code input means 89 is for inputting an authentication code corresponding to the identification code A of each computer. In the present embodiment, the code input means 89 is constituted by ten keys provided on an operation panel (not shown) of the stencil printing apparatus 5. The authentication code storage unit 87 is configured by a nonvolatile RAM that stores the authentication code input by the code input unit 89. The output unit 90 reads out the counting result for each identification code stored in the storage unit 84, that is, the charge management table, and outputs the identification code and the counting result in association with each other on a display device.
[0047]
The control means 80 is constituted by a CPU, determines whether or not the identification code A is given to the print data B, and determines that the identification code A is not given to the print data B stored in the print data storage means 81. When the determination is made, the print data stored in the print data storage unit 81 is deleted, and when it is determined that the identification code A is added to the print data B, the print data based on the print data stored in the print data storage unit 80 is determined. It has a function of controlling each part of the stencil printing apparatus 5 to perform stencil making and printing.
[0048]
The control unit 80 has a function of recognizing the size of the master by comparing the movement amount of the master detected by the detection unit 85 with the base paper size stored in the base paper size storage unit 86. When the identification code A transmitted together with the print data B and the authentication code stored in the authentication code storage unit 87 are the same, the control unit 80 executes plate making and printing based on the print data B in the stencil printing apparatus 5. It has a function to make it work.
[0049]
The operation of the management function having such a configuration will be described with reference to the flowchart shown in FIG. In this embodiment, it is assumed that the authentication code is input from the numeric keypad and is already stored in the authentication code storage unit 87.
[0050]
In step S1 of FIG. 5, the reception and storage of the print data B from the computer are performed. For example, all the print data B transmitted from the computer 1 to the stencil printing apparatus 5 is temporarily stored in the print data storage unit 81, and the process proceeds to step S2. In step S2, it is determined whether or not the identification code A is added to the transmitted and stored print data B. Here, the authentication code stored in the authentication code storage unit 87 is compared with the identification code A. As a result, if the identification code A is added to the print data B, the process proceeds to step S3.
[0051]
In step S3, it is determined that the transmitted print data B is data transmitted from the authenticated computer, and the plate making section 3 performs plate making using the print data B for one version of the transmitted print data B, and thereafter, As described above, the operation of each section of the stencil printing apparatus 5 is controlled by the control means 80 to execute printing.
[0052]
In parallel with these plate making and printing operations, in step S4, the master size used for plate making compares the number of steps of the pulse motor 32 detected by the detection unit 85 with the number of steps stored in the document size storage unit 86. It is determined by that. As a result of this comparison, if the master is an A3 size master, the flow proceeds to step S5 to count the number of plate making operations in the A3 size by the counting means 83. If the master is not an A3 size master, the flow proceeds to step S9 and proceeds to step S9. The number of times of plate making in A4 size is counted by the counting means 83. Here, the number of times of plate making for the master of each size is added and stored.
[0053]
After counting for each master size, the process proceeds to step S6, where the number of times of printing is counted by the counting means 83. Here, irrespective of the master size, the number of prints for the print data per plate is added and stored, and the process proceeds to step S7. In step S7, each coefficient result is stored for each identification code. In this step, the ID and ID as the identification code, User, the master size indicated by A3 Master Making and A4 Master Making, and the number of prints indicated by Print are stored in the charging management table of the storage means 84 shown in FIG.
[0054]
After writing into the charge management table, the process proceeds to step S8, and it is determined whether or not the next print data is stored in the print data storage unit 81. Here, when the next data, for example, the second print data from the computer 1 is stored in the print data storage unit 81, the flow returns to step S3, and a series of flow contents up to step S8 are executed. If the next print data is not stored in the print data storage unit 81 in step S8, this control ends.
[0055]
In step S2, if the identification code A is not added to the print data B, the process proceeds to step S10, where the transmitted print data B is discarded, and this control ends. Here, the print data B stored in the print data storage unit 81 is deleted.
[0056]
In order to display the information stored in the charge management table on the display device, the user operates an operation panel (not shown) of the plate printing apparatus 5 to operate the charge management display key, and operates the charge management display key for each identification code stored in the storage means 84. The counting result is read out, and the identification code is associated with the counting result as shown in FIG. In this case, the stencil printing device 5 is a display device.
[0057]
Printing by the stencil printing device 5 is expensive in terms of cost unless at least a plurality of the same contents are printed, so if the number of output of the same contents in the accounting management table is small, the display device is set to the printer 7 and the stencil printing is performed. What is necessary is just to transmit the data of the accounting management table from the output unit 90 of the device 5 to the printer 7 and print it. By printing such print management contents, the user of the computer or the stencil printing apparatus 5 or the manager of the network 6 can easily know the exact number of times of plate making and printing.
[0058]
As described above, when the identification data A is not added to the print data B transmitted to the stencil printing device 5, the print data B is deleted, and thus the data from the computer not officially connected to the network 6 is transmitted. The print data B is not used for plate making or printing. When the identification data A is added to the print data B transmitted to the stencil printing apparatus 5, the stencil making and printing are executed based on the regular print data B from a computer officially connected to the network 6. Since the number of times of plate making and the number of times of printing are counted, printing management on the network 6 can be performed with high accuracy, printing due to unauthorized access can be prevented, and the accuracy of managing the number of times of plate making and printing can be improved.
[0059]
The counting means 83 also counts, for each identification code, billing information corresponding to the base paper size based on the printing data used for plate making and printing stored in the billing information storage unit 82, and the storage means 84 calculates billing information corresponding to the base paper size. Are also classified for each identification code, accounting management can be performed in consideration of the master size, and print management accuracy is further improved.
[0060]
When an authentication code corresponding to the computer identification code A input by the code input means 89 is stored in the authentication code storage means 87, and the identification code A transmitted together with the print data B matches the stored authentication code. Since printing is performed based on the print data B having the identification code A attached to the print data B, it is possible to prevent plate making and printing using print data B to which a different identification code, that is, an identification code that is not authenticated, is added, and higher accuracy is achieved. Perform print management.
[0061]
In the above-described embodiment, the print data B without the identification code A is discarded. However, the absence of the identification code A means that the print data B is not transmitted from a computer that is not properly connected to the network 6. You can see. Therefore, in the embodiment shown in FIG. 8, a prepress / print rejection notification signal is transmitted to the computer that has transmitted the print data B to which the identification code A has not been added, to urge a warning.
[0062]
In the present embodiment, as shown in FIG. 8, when the control unit 80 determines that the identification code A is not added to the print data B, the control unit 80 sends the print data B without the identification code A to the computer that has transmitted the print data B. The stencil printing apparatus 5 is provided with a transmission management unit 88 for transmitting the stencil making / print refusal notification signal E. The transmission management unit 88 specifies, from the network address D, the computer that has transmitted the print data B to which the identification code A has not been assigned, and transmits a prepress / print rejection notification signal E to the specified computer.
[0063]
In order to specify the computer that has transmitted the data to the stencil printing apparatus 5, when transmitting the print data B from the computer, the network address D is transmitted together with the print data B, and the print data storage is performed. When the print data B is stored in the means 81, the network address D is also stored in association with the print data B.
[0064]
Hereinafter, the control of this embodiment will be described with reference to the flowchart shown in FIG.
In step T1, print data is received and stored from the computer. For example, all print data B including the network address D transmitted from the computer 1 to the stencil printing apparatus 5 is temporarily stored in the print data storage unit 81, and the process proceeds to step T2. At step T2, it is determined whether or not the transmitted print data B is provided with the identification code A. If the print data B is provided with the identification code A, the process proceeds to step T3, and the process proceeds to step T3. The processes having the same contents as those shown in steps S3 to S8 are executed in each of the steps T3 to T8, and the process ends.
[0065]
If the identification code A is not assigned to the print data B in step T2, the process proceeds to step T10, where the identification code A stored in the print data storage unit 81 is stored together with the print data B to which the identification code A is not assigned. The computer which transmitted from the network address D is specified, and a prepress / print rejection signal E is transmitted to the computer, and the process proceeds to step T11. Here, the identification code A is assigned to the computer having the network address D to which the identification code A is not assigned by sending the plate making / printing rejection signal E with the network address D assigned by the transmission management unit 88. It is possible to reliably transmit the prepress / print rejection signal E to an unauthorized computer.
[0066]
In step T11, the print data B to which the identification code A is not assigned is discarded, and the process proceeds to step T8. In step T8, if the next print data is stored in the print data storage unit 81, the process returns to step T3 and the steps up to step T8 are repeated. If the next print data is not stored in the print data storage unit 81, this control is ended.
[0067]
In this embodiment, since the print data B to which the identification code A is not assigned is deleted, print management on the network 6 can be performed with high accuracy, and the computer that has transmitted the print data B to which the identification code A has not been assigned is transmitted to the computer. Can send a stencil making / print refusal notification signal E, so that a computer that has illegally accessed the stencil printing apparatus 5 can be warned. For this reason, the user of the computer can know that the recognition code for the stencil printing apparatus 5 is not set in the computer being used, thereby facilitating network management.
[0068]
