Abstract

<P>PROBLEM TO BE SOLVED: To solve the problem that when printing including confidential contents is interrupted, the printing contents can be seen from the outside between printing apparatuses in a double-sided printing system for the continuous paper having a continuous configuration. <P>SOLUTION: When the indication to interrupt the printing to continuous paper is issued, it is judged whether there is printing which needs secret maintenance on a handling sheet located between a printing apparatus 130 and a printing apparatus 140. When the printing which needs secret maintenance exists between apparatuses, a blank paper page is inserted until the printing of the secret contents hides in the printing apparatus 140 from printing apparatus 130 side. Moreover, when the printing which does not need secret maintenance exists between apparatuses, the printing is then interrupted. In the way, the disclosure of the secret contents and useless consumption of paper can be suppressed. <P>COPYRIGHT: (C)2008,JPO&INPIT

Description

  The present invention relates to a printing system in which two printing apparatuses are arranged in succession to perform double-sided printing on continuous paper, and particularly when printing is stopped in order to ensure security when printing is stopped halfway. The present invention relates to a technique of inserting a dummy page such as a blank sheet between continuously arranged printing apparatuses.

  In a basic business where it is necessary to print a large amount of printed matter such as slips or invoices, a method is used in which two printing apparatuses are arranged in succession to perform double-sided printing on a long continuous paper. In this printing system, a sheet reversing unit for reversing the front and back of a sheet and a buffer unit for adjusting the conveyance state of the sheet are arranged between two printing apparatuses, and printing of one side is performed in the first printing apparatus. In the second printing apparatus, the other side is printed. This printing system is large in order to output continuous paper at a high speed of several tens of meters / minute or more, and each device is independent so that the above-described continuous structure can be flexibly configured. For this reason, in this printing system, the apparatus is exposed. This technique is described in Patent Document 1, for example.

JP 2005-219333 A

  By the way, printing may be temporarily stopped in order to check the printing state. At this time, in the printing system having the above-described continuous structure, the printing contents may be seen by a third party because the printing apparatuses are exposed. In particular, a printing apparatus used in a basic business is large, and thus the distance at which a sheet can be seen between the printing apparatuses is long. Therefore, it is easy for third parties to touch the printed content when printing is paused. If the printed content contains personal data, it is necessary to ensure security so that it cannot be seen by third parties. For this reason, in the printing system having the above-described continuous configuration, it is necessary to prevent the printed matter exposed between the printing apparatuses when printing is temporarily stopped by some method. As a method for solving this problem, a structure that covers the entire system with a cover is conceivable, but the continuous printing system is one of the features that the device can be installed flexibly according to the installation location. Such a structure that covers with a cover is difficult in terms of cost.

  SUMMARY OF THE INVENTION Accordingly, the present invention provides a configuration in which, in a printing system in which two printing apparatuses are continuously arranged, printing contents with high confidentiality are not exposed to human eyes between printing apparatuses when printing is temporarily stopped. Objective.

  The present invention relates to a continuous paper printing system in which printing devices for printing on continuous paper are continuously arranged. The continuous paper transporting means, the control means of the transporting means, and the job attributes of the print job maintain security. Determining means for determining whether or not the job attribute is necessary, and when the control unit is instructed to stop conveying the continuous paper during execution of the print job, the job attribute is If the job attribute requires security maintenance, the control means controls to insert a dummy page between the continuously arranged printing apparatuses.

  According to the present invention, when an instruction to interrupt printing is given to the control means, it is determined whether or not the print job includes print contents that require security maintenance, and security maintenance is performed. When the printing is necessary, dummy pages are inserted between the printing apparatuses so that the printed matter located between the continuously arranged printing apparatuses is hidden in the next-stage printing apparatus. As a result, it is possible to prevent exposure of highly confidential print contents between the printing apparatuses.

  Examples of the dummy page may include a blank page or a printed content that may be seen by a third party. The allocation of pages is set by allocating 1 to n pages from the top with a predetermined standard size such as A4 paper as the size of one page. The dimensions of the page can be arbitrarily set according to the print contents. In the continuous arrangement, the printing apparatuses are arranged in two rows in the front and rear, the first printing apparatus performs printing on one side of the continuous paper, and the second printing apparatus performs printing on the other side of the continuous paper. Refers to the arrangement of printing devices. It is useful to increase the cost and versatility of the printing device by using two printing devices arranged continuously as a printing device having the same basic structure and a system that reverses the paper in the middle. It is also possible to prepare a dedicated machine for front side printing in the printing apparatus and a dedicated machine for back side printing in the subsequent printing apparatus. As an arrangement structure of the two printing apparatuses in the continuous arrangement, there is a mode in which a sheet reversing unit for reversing the front and back of the sheet is arranged between them, and the two printing apparatuses are arranged in a square shape with the paper reversing unit as a vertex. Can do. However, it is also possible to arrange two printing apparatuses in a straight line.

  The print job refers to print data including data related to printing contents (drawing command), data regarding printing conditions (for example, font setting data), and data regarding attributes such as printing type. The job attribute is identified by data (command) indicating the attribute of the print content. In the present invention, data for identifying whether or not the print content requires security maintenance is used as a job attribute. The instruction to stop transporting continuous paper is triggered when a printing interruption operation is performed on a control terminal or control operation unit, when a paper jam or printing failure is detected, an abnormality detection signal is output from the security system. For example, a case where a power outage is detected is output.

  In the present invention, the print job includes a print job having a job attribute that requires security maintenance and a print job that is not so. During execution of the print job, the print job is sent to the control means. When the conveyance stop is instructed, the determination unit determines whether or not the print content having the job attribute requiring security maintenance exists between the continuously arranged printing apparatuses, and the determination result is Based on the above, it is preferable that the control unit performs control to insert a dummy page between the continuously arranged printing apparatuses. According to this aspect, when the conveyance of the paper is stopped, the determination unit determines whether or not there is a printed matter that needs to maintain security in a portion where the printing paper between the front and rear printing apparatuses is exposed. Is done. If there is print content that requires security between the printing devices when the paper transport is stopped, the dummy page is inserted until the portion moves to a position hidden in the next-stage printing device. . By doing so, it is possible to prevent printing contents requiring security maintenance from being exposed to the outside when the conveyance of the paper is stopped. Further, when content that does not require security maintenance is located between printing apparatuses when printing is stopped, dummy page insertion control is not performed, so paper resources are not wasted.

  In the present invention, it further comprises authentication means for authenticating the operator's identification data, and when the conveyance stop is instructed to the control means by manual control, the control means inserts a dummy page based on the result of the authentication. It is desirable to perform. According to this aspect, the operator who performed the conveyance stop operation by the authentication unit is identified, and it is determined whether or not the operator is a person who is permitted to view the print contents. For example, the data of the ID card held by the operator is read, and it is determined whether or not the operator is a person permitted to contact the confidential information. When printing is interrupted by a human operation that is allowed to contact confidential information, it is determined that there is no need to conceal the exposed print contents between the printing apparatuses, and dummy pages are inserted. Absent. If the identification data cannot be authenticated, it is determined that printing has been interrupted by a human operation that is not allowed to contact confidential information, and a dummy page is set so that the printing content is not located between the printing apparatuses. Insertion control is performed. This prevents the contents printed by a third party from leaking. Further, according to this aspect, when a person permitted to contact confidential information performs an operation to stop conveyance, dummy pages are not inserted, so that wasteful consumption of paper resources can be suppressed. it can.

  The printing method of the present invention is a printing method using a continuous paper printing system in which printing devices for printing on continuous paper are continuously arranged, and is instructed to stop conveyance of the continuous paper during execution of a print job. An instruction step, a determination step for determining whether or not the job attribute is a job attribute that requires security maintenance, and a control for inserting a dummy page between the consecutively arranged printing apparatuses based on the determination result And a step. The invention of the printing method can also be understood as a printing control program that causes a computer to read and execute each step.

  According to the present invention, in a printing system in which two printing apparatuses are continuously arranged, when printing is temporarily stopped, the job attribute of the print job is determined, and when the job attribute requires security maintenance, A dummy page is inserted so that it is exposed between the printing apparatuses and the printed content is not visible to the human eye. Accordingly, it is possible to prevent a third party from touching the highly confidential print contents of the printing paper existing between the printing apparatuses when printing is interrupted. If the job attribute does not require security maintenance, dummy pages are not inserted, and wasteful paper consumption can be suppressed.

1. First embodiment (configuration of the embodiment)
FIG. 1 is a schematic diagram showing an outline of a printing system using the invention. FIG. 2 is a conceptual diagram showing an outline of the printing system shown in FIG. In the printing system shown in FIG. 1, a control terminal 100 controls a front-stage printing apparatus 130 and a rear-stage printing apparatus 140 that are continuously arranged (also referred to as a multi-continuous arrangement). The control terminal 100 includes a terminal main body 102, a keyboard 103, and a display 104, and a front end print controller 101 is connected thereto. The terminal main body 102 stores a control program necessary for operating the front-end print controller 101, and also stores an operation program related to a print interruption process described later. It also has a function to execute these programs. The keyboard 103 is used when operating the control terminal 100. Although not shown, the terminal 103 also has an operation function using a GUI (graphical user interface) using a normal mouse. The display 104 displays information necessary for operating the control terminal 100.

  The front-end print controller 101 stores print data input via a recording medium or the network, and controls the drawing commands, print condition control data, and print timing necessary for printing in the print controllers 122 and 124. The control signal is output. In this example, since duplex printing is performed, for example, drawing commands for the first, third, fifth, and odd pages are sent to the print controller 122, and the second, fourth, and sixth pages are sent to the print controller 124. Drawing commands for the page and even pages are sent. The control terminal 100 is connected with a UPS (uninterruptible power supply) 110 for backing up the power supply of the control terminal 100 at the time of a power failure.

  The printing device 130 is a front-side printing device and is controlled by the print controller 122. The printing apparatus 140 is a latter-stage printing apparatus and is controlled by the print controller 124. The printing apparatuses 130 and 140 are the same apparatuses, and are selectively used as the front-stage printing apparatus or the rear-stage printing apparatus depending on the difference in the mounting state of the internal option unit.

  As shown in FIG. 2, the printing apparatus 130 is equipped with a printing paper loading unit 131 that includes a printing paper roll 131 a that winds continuous paper as printing paper. Further, the printing apparatus 130 is equipped with a paper carry-out unit 137 for carrying out printing paper that has been printed on one side to the outside of the printing apparatus 130. The printing apparatus 130 includes a transport unit 133 for transporting the print paper 132 unwound from the print paper roll 131a. Further, a transfer drum 134 that secondarily transfers the toner image onto the printing paper 132 to be conveyed and a photosensitive drum 135 that primarily transfers the toner image to the transfer drum 134 are disposed. A latent image is electrostatically formed on the photosensitive drum 135 by an exposure scanning device called ROS (raster optical scanner) (not shown). Corresponding to the latent image, toner is selectively supplied onto the photosensitive drum 135 from a developing device (not shown), and a toner image is formed on the surface of the photosensitive drum 135. This toner image is primarily transferred from the photosensitive drum 135 to the transfer drum 134, and the primary transfer image is secondarily transferred to the printing paper 132.

  Reference numeral 136 denotes a flash fixing unit. The flash fixing unit 136 instantaneously heats the toner image on the printing paper that passes in the middle of conveyance to fix the image. The flash fixing unit includes a xenon lamp 136a, and the toner is fixed by heat generated by light emission of the xenon lamp. The printing paper 132 on which the toner image has been fixed is carried out of the apparatus from the paper carrying-out unit 137.

  Reference numeral 138 denotes an internal control unit for controlling the operation of the printing apparatus 130. The internal control unit 138 is connected to the print controller 122 via a network of an appropriate standard, and receives a control signal for controlling a drawing command, print condition control data, print timing, and the like from the print controller 122.

  The printing apparatus 130 prints the overlapping mark on the printing paper 132. The overlapping marks are printed at a predetermined interval regardless of the print contents. This overlapping mark functions as a mark for alignment when printing on the back side in the printing apparatus 140. The overlapping mark also functions as a mark for determining the page position on the printing paper 132 which is continuous paper.

  As shown in FIGS. 1 and 2, a buffer / auxiliary transport unit 125 and a sheet reversing unit 126 are arranged between the printing apparatus 130 and the printing apparatus 140 that are continuously arranged. The buffer / auxiliary transport unit 125 has a function of stabilizing the transport state of the printing paper 132 transported between the printing device 130 and the printing device 140 and suppressing loosening, twisting, flapping, and the like of the printing paper 132. Further, the buffer / auxiliary transport unit 125 has a buffering function that always maintains the length of the printing paper 132 existing between the printing device 130 and the printing device 140 during printing. The paper reversing unit 126 includes a turn bar 127 inclined by 45 degrees with respect to the paper conveyance direction of the printing apparatuses 130 and 140, and has a function of changing the conveyance direction of the printing paper 132 by 90 degrees and reversing the front and back of the printing paper 132. . With this function, the printing device 140 performs printing on the other surface of the printing paper 132 that has been printed on one surface in the printing device 130.

  As shown in FIG. 2, the printing apparatus 140 includes a paper carry-in unit 141. The paper carry-in unit 141 has a function of taking the printing paper 132 whose front and back are reversed by the paper reversing unit 126 into the printing apparatus 140. The paper carry-in unit 141 includes an optical sensor 148 that detects a double mark printed by the printing apparatus 130. Based on the output signal of the optical sensor 148, the printing timing of a predetermined content in the printing apparatus 140 is controlled, and alignment necessary for double-sided printing is performed.

  A transport unit 143 is disposed following the paper carry-in unit 141. The transport unit 143 is the same as the transport unit 133 of the printing apparatus 130. Further, the printing apparatus 140 includes a transfer drum 144 and a photosensitive drum 145. The transfer drum 144 is the same as the transfer drum 134 of the printing apparatus 130, and the photosensitive drum 145 is the same as the photosensitive drum 135 of the printing apparatus 130. A flash fixing unit 146 is provided following the transfer drum 144. The flash fixing unit 146 is the same as the flash fixing unit 136 of the printing apparatus 130. The printing paper 132 on which the image on the other surface is fixed in the flash fixing unit 136 is taken up in the paper take-up unit 147. The paper take-up unit 147 includes a take-up roller 147a that takes up the print paper 132 that has been printed on both sides.

  In the configuration shown in FIGS. 1 and 2, data related to the printing timing of the double mark in the printing apparatus 130 and data related to the detection timing of the double mark in the optical sensor 148 are printed via the control units 138 and 149. Sent to controllers 122 and 124. The print controllers 122 and 124 manage page information in real time in the page management table based on this data. The front-end print controller 101 analyzes the data and grasps in real time where a predetermined position of the printing paper exists. Further, when the printing apparatuses 130 and 140 are installed, data regarding the length of the printing paper 132 existing between the two printing apparatuses is stored in the front-end print controller 101. Based on these data, the control terminal 100 can determine whether or not a predetermined print content exists between the printing apparatuses 130 and 140 (that is, outside the printing apparatus) during printing. .

  Further, the printing apparatuses 130 and 140 have the same main part, and by selecting a unit for loading and unloading printing paper, the printing apparatus on the front side and the printing apparatus on the rear stage are properly used. Yes. Although an example of using ordinary continuous paper has been described here, cut paper can be used as continuous paper. The cut paper is a continuous paper in which perforations are formed at a predetermined interval on a long continuous paper, and can be cut at appropriate perforations. When cut paper is used, it is not wound into a roll but is alternately folded at the perforation and stored in a dedicated storage box. When cut paper is used, the printing paper loading unit 131 and the paper take-up unit 147 may be replaced with units corresponding to the cut paper. In addition, a unit that supplies and collects paper and further performs a cutting process may be prepared separately and disposed in the front stage of the printing apparatus 130 or the rear stage of the printing apparatus 140.

(Operation of the embodiment)
FIG. 3 is a flowchart illustrating an example of the operation of the printing system illustrated in FIGS. 1 and 2. When the control terminal 100 is operated and printing is instructed while printing is being performed on continuous printing paper, the processing shown in FIG. 3 is executed in the control terminal 100 and the front-end print controller 101. That is, when printing interruption is instructed, printing interruption processing starts as shown in FIG. 3 (step S301), and it is determined whether or not the job attribute of the print job of the printing indicates the security mode (step S301). S302). If a command indicating a job attribute indicating the security mode is included in the print job, the process proceeds to step S303. If not, a process for stopping the conveyance of the printing apparatus is performed (step S305), and the print is interrupted. The process ends (step S306).

  In step S <b> 303, it is determined whether or not the printing portion to be secured is in the space between the upstream printing apparatus 130 and the downstream printing apparatus 140. At this time, the front-end print controller 101 refers to the information on the page where the print to be secured exists and the page information stored in the page management table of each of the print controller 122 and the print controller 124 and becomes the security target. It is determined whether a page where printing is present is in a space between the preceding printing apparatus 130 and the succeeding printing apparatus 140.

  If the decision result in the step S303 is YES, a command for executing a process of sending one blank page from the preceding printing device 130 to the succeeding printing device 140 is sent from the front end printing controller 101 to the printing controller 122. A command for instructing winding of the paper in response to the blank page is output from the front-end print controller 101 to the print controller 124 (step S304). When step S304 is executed, the determination in step S303 is performed again. Even at this stage, if the printing portion to be secured exists outside the apparatus, the process of inserting one blank page is executed again (step S304). On the other hand, if there is no security target print portion outside the apparatus, the process advances to step S305 to stop printing paper conveyance. That is, blank page insertion processing is performed until the security target print portion is stored in the subsequent printing apparatus.

  According to the above operation mode, when an instruction to interrupt printing is performed while continuous printing is being performed on continuous paper, it is determined whether or not the print content to be secured exists between the devices, If the printing content exists between the apparatuses, a blank page is sent from the preceding printing apparatus to the succeeding printing apparatus. As a result, the print contents to be secured are kept from being seen by the human eye. If printing that is not a security target is being performed, the determination in step S302 is NO, so no blank page is inserted, and the conveyance of the printing paper is immediately stopped.

2. Second Embodiment (Configuration of Embodiment)
In this embodiment, in the printing system according to the first embodiment, when a person who is not allowed to view the highly confidential confidential print contents performs a print interruption operation, a blank page is displayed. Insert. When a person who is permitted to view the highly confidential print contents to be secured performs a print interruption operation, no blank page is inserted.

  In this embodiment, a password is given to a party who is allowed to contact confidential information to be printed. When the control terminal 100 is controlled, a screen for requesting input of a password is first displayed on the display 104. Then, when the concerned person operates the control terminal 100, the password given first is input from the keyboard 103. When a person who has not been given a password operates the control terminal 100, the password need not be entered. Even in this case, the terminal 100 can be operated.

  As identification data for identifying a predetermined party, biometric authentication data such as fingerprints and irises, and electronic identification data stored in a magnetic card or IC card can be used in addition to the password described above. When these identification data are used, an appropriate interface that can read the identification data may be prepared. For example, if fingerprint authentication is used, the fingerprint reading device is connected to or arranged on the control terminal 100. Then, the fingerprint data stored in advance in the terminal body 102 and the fingerprint data read by the fingerprint reading device are collated in the terminal body 102 to determine authenticity.

(Operation of the embodiment)
FIG. 4 is a flowchart for explaining an example of an operation procedure according to this embodiment. In the present embodiment, the following processing is executed in the control terminal 100 and the front-end print controller 101. When the control terminal 100 is operated to instruct printing interruption, the printing interruption process (S401) is started, and whether or not the identification data (in this case, the password) of the operator operating the control terminal 100 has been acquired. Determination is made (step S402). If the identification data has been acquired, the process proceeds from step S402 to step S403; otherwise, the process proceeds from step S402 to step S404. In step S403, whether or not the acquired identification data matches the identification data stored in the control terminal 100 in advance is checked, and if the authenticity of the identification data is confirmed, the process proceeds to step S407. The process for proceeding and stopping the conveyance of the printing paper is executed, and the printing interruption process is terminated (step S408). If the authenticity of the identification data cannot be confirmed in step S403, it is determined whether or not the job attribute is a security mode (step S404). The details of the determination in step S404 are the same as the determination in step S302 of FIG.

  If the job attribute is the security mode, the process advances from step S404 to step S405, and it is determined whether or not the print content to be secured exists outside the printing apparatus. In step S405, if the print content is located outside the printing apparatus, a process of inserting one blank page is executed (step S406). Otherwise, a process of stopping the conveyance of the printing paper is performed. (Step S407). Even if one blank page is inserted, if the print contents to be secured are still located outside the printing apparatus, the process proceeds from step S405 to step S406, and another blank page is inserted. Processing is executed. Then, when the print contents to be secured are not located outside the apparatus, the process proceeds from step S406 to step S407, an instruction to stop the conveyance of the printing paper is issued, and the print interruption process ends (step S408). .

  According to the present embodiment, when a person qualified to contact confidential information stops printing, the blank page is not inserted and printing is interrupted. On the other hand, when a person who is not qualified to contact confidential information stops printing, a blank page is automatically inserted so that the print content subject to security is not exposed between devices, and the print content Is controlled so as to be stored in the next-stage printing apparatus.

3. Third Embodiment A specific example in the case where blank page insertion is performed by applying the processing shown in FIG. 3 will be described. FIG. 5 is a conceptual diagram showing a state of printing on the printing paper. In FIG. 5, the front surface of the printing paper 132 is shown on the upper side, and the back surface thereof is shown on the lower side.

  In the printing system shown in FIGS. 1 and 2, it is assumed that the operation terminal 100 is operated and printing is instructed while printing on continuous paper is being performed. Further, it is assumed that the printing state at this time is the state shown in FIG. In FIG. 5A, double-sided printing of job 1 is completed up to 5 pages on printing paper 132, and printing of jobs 2 to 4 is completed for printing of even-numbered pages by the preceding printing apparatus 130. A state in which odd-numbered pages are to be printed by the printing apparatus 140 at the subsequent stage is shown. Here, it is assumed that confidential content is printed in job 2. In this case, the print job data of job 2 includes identification data indicating that the job attribute is a job attribute that requires security maintenance. It is assumed that the other jobs 1, 3, and 4 have low confidentiality and have been printed with contents that are not problematic even if viewed by a third party.

  Now, when a print stop instruction is issued at the timing shown in FIG. 5A, the flow of the print interruption process shown in FIG. 3 starts. In this case, since the job 2 to be secured is included in the print content, the determination in step S302 in FIG. 3 is YES, and the determination in step S303 is performed. In the state shown in FIG. 5A, since the odd page of the job 2 to be secured is located between the printing apparatuses 130 and 140, the determination in step S303 is YES. As a result, one blank page is inserted. That is, a blank for one page is sent out by the printing apparatus 130, and the printing paper 132 shown in FIG. 5 moves by one page in the left direction in the drawing.

  However, in the state of FIG. 5A, even if the printing paper 132 moves to the left by one page, the print content portion of job 2 is not hidden in the printing apparatus 140. Therefore, the determination in step S303 performed after step S304 is YES again. As a result, the process proceeds to step S304, and one blank page insertion process is performed again. In this example, even if a total of two blank pages are inserted on the printing apparatus 130 side in the state shown in FIG. 5A, the third page of job 2 is not completely hidden in the printing apparatus 140 yet. . Accordingly, the determination in step S303 after step S304 for the second time is also YES, and the third blank page insertion process is performed. As a result, the state shown in FIG.

  In the state shown in FIG. 5B, three blank pages are inserted on the printing apparatus 130 side from the state shown in FIG. 5A, and the entire printing paper 132 is accordingly transferred from the printing apparatus 130 to the printing apparatus 140. It is in a state shifted to. In this case, the determination in step S303 is NO, and the conveyance of the printing paper is stopped (step S305). In the state shown in FIG. 5B, the contents of job 2 are hidden inside the printing apparatus 140, so that the contents of job 2 are not exposed to human eyes. In this way, a process is performed to prevent the print content desired to maintain confidentiality from being exposed outside the apparatus.

  In this example, when a blank page is inserted on the printing apparatus 130 side and the printing paper 132 is conveyed from the printing apparatus 130 toward the printing apparatus 140, the printing apparatus 140 prints on the carried-in portion ( In this case, even-numbered pages are printed).

  The determination in step S303 is performed as follows. That is, the optical sensor 148 reads a duplicate mark (not shown), the read signal is converted into a data signal of an appropriate standard in the control unit 149, and the data signal is sent to the print controller 124. Based on this data signal, the page management table in the print controller 124 manages the data relating to the page position while being updated in real time. On the other hand, the print controller 122 similarly manages the page position on the printing apparatus 130 side. Accordingly, the front-end print controller 101 determines the position of the job based on the management data and the data relating to the length of the printing paper 132 between the apparatuses stored in advance. And based on this result, determination of step S303 in the control terminal 100 is performed.

  The present invention can be used in a technique in which two printing apparatuses are continuously arranged to perform double-sided printing on continuous paper.
