Abstract

<P>PROBLEM TO BE SOLVED: To provide an authentication system for a printing apparatus that can strictly monitor and prevent unauthorized printing by particular authorized users while preventing unauthorized use by strangers by means of portable storage media. <P>SOLUTION: A multifunction machine 7 (printing apparatus) is used such that authentication based on identifiers (identification information) by data exchange between IC cards MC and a card reader 5 authorizes only particular users (registrants) to access the multifunction machine 7 for printing. In the authentication system, the card reader 5 and multifunction machine 7 are communicatively connected to a management server 2 (database server). Information on print contents printed by the multifunction machine 7 (such as image data corresponding to the print original, a reference number unique to the data, a title of the data, and the printing date/time) is managed in the management server 2 in association with the identifiers authorizing the printing. <P>COPYRIGHT: (C)2007,JPO&INPIT

Description

  The present invention stores specific identification information for each medium in a storage medium such as a non-contact type IC (integrated circuit) card, and reads the identification information to use a predetermined printing device. The present invention relates to an authentication system for a printing device that performs authentication according to the above.

  In recent years, so-called non-contact type IC cards are spreading in companies and schools (particularly universities). As a system using such an IC card, for example, residual value information (such as electronic money) indicating the degree of payment ability and identification information (ID data) unique to each medium are stored in the card. A system for collecting and authenticating a value based on data exchange (data communication) with a data reading / writing device that reads / writes information stored in an IC card is known (see, for example, Patent Document 1).

Specifically, in this system, a local area network (LAN) is constructed by a required number of the data reading devices, and each printing device (printer, Predetermined authentication is required for the use of copiers, scanners, etc. That is, the use of these printing devices is permitted only to a specific user (a person registered in advance) through authentication based on the identification information of the IC card.
JP 2004-341735 A

  As described above, according to the above-described conventional authentication system, it is certain that unauthorized use is performed by a suspicious person by limiting the use of a printing device to only a specific user (a person registered in advance). This will be prevented beforehand. However, in such a system, it is not assumed that illegal printing is performed by a specific user permitted to use, and there is still room for improvement.

  That is, in general, documents relating to confidential information are, in principle, strictly prohibited and prohibited from printing at companies and schools. However, in reality, it may be necessary to take it out for use in a meeting, or it may be necessary to print only a limited number of sheets for presentations. However, it is difficult to completely prohibit printing. For this reason, even when a system in which the use of a printing device is limited to only a specific user, such as the above-described conventional authentication system, unauthorized printing is performed by a specific user permitted to use the printing device. There are still strong concerns about what is going on.

  The present invention has been made in view of such circumstances, and it is possible to prevent unauthorized use by a suspicious person using a portable storage medium, while also performing unauthorized printing by a specific user permitted to use, An object of the present invention is to provide a printing device authentication system capable of closely monitoring this and preventing it.

  In order to achieve such an object, according to the present invention, a portable storage medium storing identification information unique to each medium and a data reader that at least reads information stored in the storage medium. As a printing device authentication system that performs data communication and permits printing by a predetermined printing device by authentication based on the identification information, the data reading device and the printing device have a database for managing predetermined information; It connects so that communication is possible, It is comprised so that the information regarding the printing content printed at least by the said printing apparatus may be linked | related for every identification information which permitted the printing, and it is managed by the said database as said predetermined information.

  According to such a configuration, the information related to the print contents is managed in association with each identification information, so that it is possible to accurately grasp who printed what. In other words, even if a document related to confidential information is illegally printed, it is immediately obvious who has leaked which information. It will be possible to suppress. In general, the easy identification of the criminal also leads to prevention of fraud (in this case, the leakage of confidential information). As described above, with the above-described configuration, unauthorized use by a suspicious person using a portable storage medium is prevented, and unauthorized printing by a specific user permitted to use is strictly monitored. And it will be possible to prevent it.

  Further, in this case, the information related to the printing contents managed by the database includes at least one of image data corresponding to the original plate of the printing and information specifying the image data (reference number, title, etc.). It is effective to use one. If at least one of these is associated with the identification information, it becomes possible to know who printed what.

  In addition, since the information leakage (print date and time) is also important in developing post-measures for information leakage, the information related to the print contents managed by the database includes, in addition to at least one of the above items, Furthermore, the one including the printing date is more effective.

  Further, the identification information unique to each storage medium is handled as information indicating the identity of the owner (for example, name, address, date of birth, student number, title (department / officer, teacher / student, etc.)) This makes it easy to manage information in the database. This makes it easier to identify the criminal. It is also convenient when processing restrictions are set for specific media holders (for example, when a storage medium that has been stolen is disabled, or when the authority of a student is restricted at a school more than the teacher). is there.

  If the storage medium is to be wirelessly communicated with the data reader, the trouble of inserting / removing the storage medium (for example, IC card) in the data reader, forgetting to remove the storage medium, failure of the apparatus, etc. As a result, the convenience of the entire system is improved and the storage medium (for example, an IC card) is prevented from being stolen.

  As the printing apparatus, for example, an apparatus that reads image data corresponding to an original and performs printing based on the image data (for example, a printer) or an original (original) placed on a reading surface (original table). A printing device such as one that reads and prints based on the original (for example, a copying machine or a scanner) can be used.

  In general, the printing speed of the printer is much slower than the processing speed of the computer, so it is very inefficient to wait for the printer to finish printing after issuing a printing command to the printer. Therefore, after temporarily storing (spooling) printing data in an external storage device (for example, a buffer or a hard disk) so that the CPU (central processing unit) can execute the next command as soon as possible, The printing process proceeds with the data on the external storage device. For this reason, in the case of the former configuration (configuration for reading image data) of the above two configurations, such spool data (in order to improve processing efficiency during the printing) is used as information related to the print contents managed by the database. As a result, it is possible to more easily and efficiently realize the association between the information related to the print content and the identification information. It becomes like this.

  The data reading device is a data reading device that not only reads but also rewrites information stored in the storage medium, and the storage medium has a degree of payment ability of one or more types together with the identification information. Is stored on the basis of the fact that the storage medium is communicably presented to the data reader, the remaining price information of the storage medium is used for the printing device. This is particularly effective as a configuration for collecting such consideration (rewriting residual value information).

According to such a configuration, a highly convenient and efficient collection of charges is performed by the portable storage medium.
In this case, the portable storage medium includes, for example, electronic money, electronic money indicating the degree of payment ability only for devices in a specific local area network as residual value information indicating the degree of payment ability. It is desirable to store at least one or two or more point money, which is a general price that can be used only for a predetermined printing device that is associated in advance with general-purpose electronic money that can be used for all supported models. If such residual value information is used, it is possible to efficiently collect the consideration information.

  Hereinafter, an embodiment embodying an authentication system for a printing device according to the present invention will be described with reference to FIGS. Note that, as an authentication system according to this embodiment, a system using a non-contact type IC (integrated circuit) card is assumed as in the conventional system described above.

  First, the outline (schematic configuration) of this system will be described with reference to FIG. In this embodiment, the case where the authentication system is used in a school such as a university will be mentioned.

  As shown in FIG. 1, this system is roughly divided into a remote monitoring server 1 that performs communication processing, a management server 2 that manages a database, and a control computer that controls driving of a multifunction device 7 (printing device). 3 and the client computer 4 are connected to each other to construct a local area network (on-campus LAN). More specifically, here, the control computer 3 includes a card reader 5 (data reading device) for reading and writing information stored in a memory M (portable storage medium) of the IC card MC, a printer and a copying machine (copier). ) And a multifunction device 7 having a printing function as a scanner, and a touch panel 6 as an operation panel of the multifunction device 7, respectively. As shown in FIG. 2, the memory M (IC memory) of the IC card MC includes an identifier M1 (identification information) unique to each medium, and a payment ability only for devices in the local area network. Remaining value data M2 (residual value information) made up of electronic money indicating the degree of each is stored in a predetermined storage location. In this system, based on such a configuration, data exchange (data communication) is performed between the IC card MC and the card reader 5, and more specifically, based on the identifier M1 of the IC card MC. Thus, authentication relating to the use of the multi-function device 7 communicatively connected to the card reader 5 is performed. That is, the use of the multifunction device 7 is permitted only to a specific user (a person registered in advance).

  More specifically, the client computer 4 is provided in a required number (usually a large number) in the local area network, and is operated by, for example, a student or a teacher. Based on the operation of the computer 4 (for example, using a password or the like), the set print data (print job) such as the print condition (for example, paper size or color) is associated with each identifier M1, It can be stored (stored) in a printing terminal (hard disk of the control computer 3). The stored print data (print job) can be arbitrarily deleted by the user (by the way, if it exceeds the storage capacity, it is automatically deleted in the order of the oldest storage date).

  The card readers 5 are also provided in the local area network in a required number (usually a large number) together with the multifunction machine 7 and the like that together form a printing terminal, and are respectively connected to the management server 2 and the like so as to communicate with each other. ing. Then, the data of the IC card MC read by the card reader 5 is appropriately transmitted to the management server 2. For the sake of convenience, although not shown in the figure, there are card readers connected to devices other than the printing device (multifunction device 7) (for example, cigarettes and food vending machines) in the network. The device can also be used by paying the remaining value data M2 (consideration) stored in the IC card MC.

  Further, the multifunction device 7 is configured to have a storage device (for example, a buffer or a hard disk) that temporarily stores image data (spool data) corresponding to the original plate in order to improve processing efficiency during printing. Yes. In other words, the CPU (central processing unit) of the control computer 3 can execute the next command while proceeding with the printing process using the data on the storage device. In addition, information related to the print contents printed by the multifunction machine 7 is transmitted to the management server 2 at an appropriate timing.

  In the management server 2, the identifier M1 stored in the IC card MC is treated as indicating the identity of the owner. That is, this identifier M1 is converted into information (for example, name, student number, job title (teacher / student), etc.) associated in advance in the server 2, and information relating to the print contents from the multifunction device 7 (the relevant print) The image data corresponding to the original data, the serial number unique to the data, the title of the data, the printing date and time, etc.) and the residual value data M2 are managed. For this reason, if the contents of the server 2 (information stored in the built-in database) are viewed, more specifically, if the contents are displayed on a display device (see FIG. 1) (for example, a list display), who and when Is printed (each person's print history), and how much consideration remains on the IC card (each person's residual value information).

  Hereinafter, the authentication mode by this system will be described in detail with reference to FIGS. It should be noted that the value collected here is collected as the value according to the degree of use of the multifunction device 7 (printing device).

  FIG. 3 is a flowchart showing a processing procedure related to the collection of consideration by the system. This series of processes proceeds under the control of the control computer 3 based on the operation of the touch panel 6 by the user (user).

  As shown in FIG. 3, in this series of processing, first, in step S1, the user selects a print mode. Next, in step S2, the selected mode is executed. Here, as an example, a case where four print modes of “print (net)”, “print (USB)”, “copy (copy)”, and “scan” are set will be described. In the “print (net)” mode, print data (image data corresponding to the original plate) that has been transmitted to the printing terminal (control computer 3) in advance is printed on a predetermined print sheet by the multi-function device 7. Mode. In the “print (USB)” mode, image data corresponding to the original plate is read from a storage medium in which print data is stored in advance by, for example, communication via a USB interface, and is printed on a predetermined print sheet by the multifunction device 7. It is a mode to do. The “copy (copy)” mode is a mode in which the multifunction device 7 reads an original (original) placed on a reading surface (original table) and performs copying (printing) on a predetermined printing sheet based on the original. is there. In the “scan” mode, similarly, the multifunction device 7 reads an original (original) placed on a reading surface (original table), and based on the original, image data (for example, PDF format) ( This is a mode for producing (printing) electronic data. However, in this “scan” mode, no fee is collected (free of charge).

  FIG. 4 is a flowchart showing a processing procedure (corresponding to step S2 in FIG. 3) when the “print (net)” mode is selected in step S1 in FIG. FIGS. 5A to 5C and FIGS. 6A to 6F show display contents of the screen of the touch panel 6 that change in accordance with the series of processes. First, an authentication mode when the “print (net)” mode is selected in step S1 of FIG. 3 will be described with reference to these drawings.

  That is, in step S1 of FIG. 3, the screen of the touch panel 6 is displayed as shown in FIG. 5A, and the user touches the part corresponding to the “Print (Net)” button on the screen (pressed with a finger). ) And the flowchart of FIG. 4 starts. Then, first, in step S11, predetermined preprocessing (here, authentication) is performed. That is, as shown in FIG. 6A, a message (authentication request) prompting the user to hold the IC card MC over the card reader 5 is displayed on the screen of the touch panel 6. Then, when the user holds the IC card MC held by the card reader 5, non-contact wireless communication is performed between them, and the identifier M1 ("001A") of the IC card MC is read, and FIG. As shown in (b), the touch panel 6 shifts to a password input screen. When the password set for each IC card MC (identifier M1) is correctly input by the user through the keypad KP on the screen (determined by the “OK” button), the next step S12 (FIG. 4) is performed. ). On the other hand, if the card is not held (not presented) even after waiting for a predetermined time (for example, 30 seconds) on the screen (authentication request screen) in FIG. 6 (a), or on the screen (password request screen) in FIG. 6 (b). If password entry fails for a predetermined number of times (for example, three times), or if the “end” button on these screens is pressed, the process forcibly returns to step S1 in FIG.

  In the subsequent step S12, as shown in FIG. 6C, a print job (print data associated with each identifier M1) previously transmitted (stored) to the control computer 3 on the screen of the touch panel 6 is displayed. Is displayed as a list (when it cannot be displayed on one screen, it is displayed over a plurality of pages (switched with buttons)). Further, here, the contents of the job (name, date and time of transmission, number of sheets (capacity), color (color / monochrome), consideration for printing, etc.) are also displayed to help the user to select a job. That is, the user can arbitrarily select a job to be printed. Specifically, the job selected by the cursor is displayed in a highlight color, and when the “print” button is pressed, the selection is confirmed and a check (check mark) is entered in the check box. In this way, a plurality of jobs can be selected at a time by checking the check boxes of the plurality of jobs. In addition, once the selection is confirmed, the selection can be canceled by pressing the “delete” button. Furthermore, the job (print data) itself stored in the control computer 3 can be deleted by continuing to hold down the “delete” button (long press) (or separately from the “delete” button, “ A similar function is possible even if a “delete data” button is provided). When the “print start” button is pressed in a state where selection of one or a plurality of jobs is confirmed (checked), the process proceeds to the next step S13 (FIG. 4). On the other hand, if the “end” button is pressed on the screen (job selection screen) of FIG. 6C, the printing process itself ends (returns to step S1 in FIG. 3).

  In the subsequent step S13, consideration is collected. That is, as shown in FIG. 6D, on the screen of the touch panel 6, a message (card request) prompting the user to hold the IC card MC over the card reader 5, or residual value data in the IC card MC. The balance of M2 (electronic money) (“5000 yen”), the total amount of consideration for the selected job (“500 yen”), the balance after payment (“4500 yen”), and the like are displayed. Then, when the user holds the IC card MC over the card reader 5, non-contact wireless communication is performed between them, and the value (“500 yen”) is the remaining value data M2 (electronic money) in the IC card MC. The process proceeds to the next step S14 (FIG. 4), printing (printing) is started (printed material starts to be discharged), and the touch panel 6 is also printing as shown in FIG. 6 (e). Moves to a screen (printing screen) indicating that there is. On the other hand, if the card is not held over a predetermined time (for example, 30 seconds) on the screen (fee payment screen) in FIG. 6D, or if the “return” button is pressed, the steps in FIG. Return to S1.

  As described above, in this printing (printing), in order to improve processing efficiency, image data (spool data) corresponding to the original is stored in a storage device (for example, a buffer, a hard disk, or the like) built in the multifunction machine 7. ) Is temporarily accumulated (spooled). That is, by proceeding with the printing process using the data on the storage device, the CPU (central processing unit) of the control computer 3 can execute the next command while executing printing.

  When printing (discharge of printed matter) stops, the process proceeds to the next step S15 (FIG. 4), and in this step S15, the printing process corresponding to the consideration (“500 yen”) collected in the previous step S13 is normally performed. It is determined whether or not it has been completed. In step S15, for example, due to some abnormality (for example, an error such as a paper jam, an abnormal print content, an ink out, a toner out, a paper out, a mechanical trouble, etc.) If it is determined that it has been stopped, the change (the amount of unprocessed consideration) is paid back in step S16. That is, as shown in FIG. 6 (f), on the screen of the touch panel 6, a message for prompting the user to hold the IC card MC over the card reader 5 (card request by the notification means) or a prepaid consideration (“500 Yen)), the total amount of compensation for the printing process completed normally (the amount corresponding to the usage degree of the multifunction machine 7) (for example, “400 yen”), the unprocessed part of consideration (“100 yen”), etc. Is displayed. Further, if the card is not held over after waiting for a predetermined time (for example, 30 seconds), the card request is also made by a predetermined sound (for example, voice guidance). When the card reader 5 is readable and writable in this way, when the user holds the IC card MC over the card reader 5, the remaining value data M2 (electronic money) in the IC card MC is obtained by non-contact wireless communication. On the other hand, the unprocessed value (“100 yen”) is returned, and the “balance in card” on the screen of the touch panel 6 is changed from “4500 yen” to “4600 yen” along with a sound such as “chareen”. ) Updated. Then, the process proceeds to the next step S17 (FIG. 4).

  On the other hand, when it is determined in step S15 that the printing process commensurate with the consideration has been completed normally, the payment result is displayed on the touch panel 6 as shown in FIG. 5B. The process proceeds to step S17 (FIG. 4). It should be noted that in the previous screen (refund screen) of FIG. 6 (f), if a card is not held over after waiting for a predetermined time (for example, 5 minutes), the screen of FIG. 6 (f), or FIG. 5 (b). When the “return” button is pressed on the screen (payment result screen), the process returns to step S1 in FIG.

  In the subsequent step S17, it is determined whether or not to continue printing. That is, as shown in FIG. 5C, a message indicating that printing is completed is displayed on the screen of the touch panel 6, and when the “continue printing” button is pressed by the user, for example, Return to step S12 (FIG. 4). On the other hand, when the “end” button is pressed, the process proceeds to the next step S18. In step S18, the multi-function device 7 notifies a predetermined post-process (for example, communication with the control computer 3 (FIG. 1) (exchange of required data), storage of the required data, and a message indicating that the processing has been completed normally. Is displayed (for example, “Thank you”), the process proceeds to the next step S19.

  In this step S19, printing is performed by the multifunction device 7 such as image data corresponding to the original of the printing (in this case, spool data is used), a serial number unique to the data, a title of the data, a printing date and time, and the like. The information related to the printed contents is transmitted to the management server 2 (FIG. 1), and with this processing, this series of processing ends.

  Next, referring to FIGS. 7 and 8 together with FIGS. 3 and 5, the authentication mode when the “copy” mode is selected in step S1 of FIG. 3 will be described. To do. 7 is a flowchart showing a processing procedure (corresponding to step S2 in FIG. 3) in the case where the same mode is selected in step S1 in FIG. 3, and FIGS. It is a figure which shows the display content of the screen of the touch panel 6 which changes with these series of processes.

  That is, in step S1 of FIG. 3, when the user touches (presses with a finger) a portion corresponding to the “Copy” button on the screen (FIG. 5A), the flowchart of FIG. 7 starts. First, in step S21, predetermined preprocessing (here, authentication) is performed. That is, as shown in FIG. 8A, a message (authentication request) prompting the user to hold the IC card MC over the card reader 5 is displayed on the screen of the touch panel 6. Then, when the user holds the IC card MC held by the card reader 5, non-contact wireless communication is performed between them, and the identifier M1 ("001A") of the IC card MC is read, and FIG. As shown in (b), the touch panel 6 shifts to a password input screen. When the password set for each IC card MC (identifier M1) is correctly input by the user through the keypad KP on the screen (determined by the “OK” button), the next step S22 (FIG. 7). ). On the other hand, if the card is not held (not presented) even after waiting for a predetermined time (for example, 30 seconds) on the screen (authentication request screen) in FIG. 8 (a), or on the screen (password request screen) in FIG. 8 (b) If password entry fails for a predetermined number of times (for example, three times), or if the “end” button on these screens is pressed, the process forcibly returns to step S1 in FIG.

  In subsequent step S22, as shown in FIG. 8C, the touch panel 6 shifts to a payment amount setting screen. When the user sets an advance payment amount (for example, “500 yen”) through the amount input button MB (determined by the “payment” button) on the screen, the process proceeds to the next step S23 (FIG. 7). Will be migrated. On the other hand, if the “end” button is pressed on the screen (payment amount setting screen) of FIG. 8C, the printing process itself is terminated (return to step S1 in FIG. 3).

  In the subsequent step S23, the consideration is collected. That is, as shown in FIG. 8D, on the screen of the touch panel 6, a message (card request) prompting the user to hold the IC card MC over the card reader 5, or residual value data in the IC card MC. The balance of M2 (electronic money) (“5000 yen”), the set prepaid consideration (“500 yen”), the balance after the payment (“4500 yen”), and the like are displayed. Then, when the user holds the IC card MC over the card reader 5, non-contact wireless communication is performed between them, and the value (“500 yen”) is the remaining value data M2 (electronic money) in the IC card MC. Is collected, and the process proceeds to the next step S24 (FIG. 7), the multifunction device 7 and the like enter a standby state for execution of printing (copying), and the screen of the touch panel 6 has, as shown in FIG. The remaining amount of the prepaid consideration (updated each time printing is performed), the copy fee table CC, etc. are displayed. On the other hand, if the card is not held over a predetermined time (for example, 30 seconds) on the screen (fee payment screen) in FIG. 8D, or if the “return” button is pressed, the steps in FIG. Return to S1.

  In the subsequent step S24, the user can perform copying (copying) through operation of a copy panel provided in the multifunction machine 7 itself. Specifically, the original (original) is placed (set) on the reading surface (original table) of the multifunction machine 7, and copy conditions (for example, paper size, color, magnification, duplex / single-sided printing, density, etc.) are set on the copy panel. After setting, when a “start” button on the panel is pressed, the printed material (copy material) is discharged from the multifunction device 7. Then, when the “end” button is pressed by the user on the screen (copy screen) of FIG. 8E, the process proceeds to the next step S25 (FIG. 7).

  In the subsequent step S25, it is determined whether or not there is a change (consideration for the unprocessed portion). If it is determined in step S25 that there is a change, that is, the printing process commensurate with the consideration has not been performed (the “end” button has been pressed with the prepaid compensation remaining), in step S26. Refund of change is made. That is, as shown in FIG. 8 (f), on the screen of the touch panel 6, a message (card request) prompting the user to hold the IC card MC over the card reader 5 or a prepaid consideration (“500 yen”). The total amount (for example, “400 yen”) of the value for the printing process completed normally (for example, “400 yen”), the price for the unprocessed value (“100 yen”), and the like are displayed. . Further, if the card is not held over after waiting for a predetermined time (for example, 30 seconds), the card request is also made by a predetermined sound (for example, voice guidance). When the user holds the IC card MC over the card reader 5, the unprocessed value (“100 yen”) of the remaining value data M 2 (electronic money) in the IC card MC is obtained by non-contact wireless communication. Return is performed, and “Balance in card” on the screen of the touch panel 6 is updated (from “4500 yen” to “4600 yen”) with a sound such as “chareen”. Then, the process proceeds to the next step S27 (FIG. 7). On the other hand, if the card is not held up even after waiting for a predetermined time (for example, 5 minutes) on the screen (refund screen) of FIG. 8 (f), or if the “return” button is pressed, The process returns to step S1.

  On the other hand, if it is determined in step S25 that the printing process commensurate with the consideration has been performed, the touch panel 6 becomes, for example, the screen as shown in FIG. 5B, and the change is not refunded. The process proceeds directly from step S25 to the next step S27 (FIG. 7).

  Then, in the subsequent step S27, the multifunction device 7 notifies a predetermined post-process (for example, communication with the control computer 3 (FIG. 1) (exchange of required data), storage of the required data, and a message indicating that the processing has been completed normally). Is displayed (for example, “Thank you”), the process proceeds to the next step S19.

  In this step S28, the image data corresponding to the original of the printing, the serial number unique to the data, the title of the data (only when input at the time of printing), the printing date and time, etc. are printed by the multifunction device 7. The information related to the printed contents is transmitted to the management server 2 (FIG. 1), and with this processing, this series of processing ends.

  Next, an operation mode of the system when the “print (USB)” mode is selected in step S1 of FIG. 3 will be described with reference to FIG. FIG. 9 is a flowchart showing a processing procedure (corresponding to step S2 in FIG. 3) when the same mode is selected in step S1 in FIG. Since the screen display of the touch panel 6 is basically the same as that shown in FIGS. 6A to 6F, the illustration is omitted here for convenience.

  That is, in step S1 of FIG. 3, when the user touches (presses with a finger) a portion corresponding to the “Print (USB)” button on the screen (FIG. 5A), the flowchart of FIG. 9 starts. First, in step S31, authentication (password input or the like) is performed as in step S11 (FIG. 4). Further, after this authentication, a message prompting the user to connect to a memory (storage medium) in which print data (for example, image data in PDF format) is stored in advance on the screen of the touch panel 6 (for example, connection through a USB interface). (Memory connection request) is displayed. When the memory is connected by the user (for example, connected to the multifunction device 7 or the control computer 3 via the USB interface), the multifunction device 7 starts reading (acquiring) print data.

  When the reading of the print data is completed, the process proceeds to the next step S32, followed by steps S32 to S37 of the processing contents in accordance with the previous steps S12 to S17 (FIG. 4), and in a subsequent step S38, a predetermined post- Processing is performed. That is, on the screen of the touch panel 6, a message (memory removal request) prompting the user to remove the memory connected in the previous step S31 is displayed. The memory removal request is also made by a predetermined sound (for example, voice guidance). When the memory is removed by the user, the multi-function device 7 communicates with the control computer 3 (FIG. 1) (required data exchange), stores the required data, and displays a message notifying that the operation has been completed normally ( For example, “Thank you”).

  In the subsequent step S39, the image data corresponding to the printing original (in this case, spool data is used), the serial number unique to the data, the title of the data, the printing date and time, etc. are printed by the multifunction device 7. The information related to the printed contents is transmitted to the management server 2 (FIG. 1), and with this processing, this series of processing ends.

  Next, an operation mode of the system when the “scan” mode is selected in step S1 of FIG. 3 will be described with reference to FIG. FIG. 9 is a flowchart showing a processing procedure (corresponding to step S2 in FIG. 3) when the same mode is selected in step S1 in FIG. Since the screen display of the touch panel 6 is basically the same as that shown in FIG. 8, the illustration is omitted here for convenience.

  That is, in step S1 of FIG. 3, when the user touches (presses with a finger) a portion corresponding to the “Scan” button on the screen (FIG. 5A), the flowchart of FIG. 10 starts. First, in step S41, when authentication (password entry or the like) is performed as in step S11 (FIG. 4), the process proceeds to the next step S42.

  In step S <b> 42, the user can perform scanning through the screen operation of the touch panel 6. Specifically, an original (original) is placed (set) on the reading surface (original table) of the multifunction device 7 and scanning conditions (for example, storage destination (control computer 3, removable memory, multifunction device 7 main body, etc.) After setting the document size / orientation, document type (double-sided / single-sided, etc.), color, magnification, resolution, density, etc., the “start scan” button on the screen of the touch panel 6 is pressed, so that a predetermined format ( Image data (electronic data, for example, in PDF format) is created (printed), and the image data is stored in a set storage location (storage location). If the storage destination is another medium (for example, a portable medium), a memory connection request similar to the previous step S31 (FIG. 9) is made prior to scanning.

  In this way, when all the scans are completed and the user presses the “scan end” button on the screen of the touch panel 6, the process proceeds to the next step S43. In step S43, the multi-function device 7 displays predetermined post-processing (for example, communication with the control computer 3 (exchange of required data), storage of required data, and display of a message notifying that the processing has been completed normally (for example, "Thank you")). If the storage location (storage location) of the scan data is a portable medium or the like, a memory removal request similar to the previous step S38 (FIG. 9) is also made.

  In the subsequent step S44, image data corresponding to the printing original plate (in this case, the created (printed) image data is used), a serial number unique to the data, and a title of the data (input at the time of printing) Information on the print contents printed by the multi-function device 7 such as the print date and time, and the like, are transmitted to the management server 2 (FIG. 1), and this series of processes ends with this process. .

As described above, according to the printing apparatus authentication system of this embodiment, the following excellent effects can be obtained.
(1) When using the multifunction device 7 (printing device), the identifier M1 (identification) is based on data exchange (data communication) between the IC card MC (storage medium) and the card reader 5 (data reading device). By the authentication based on (information), printing by the MFP 7 is permitted only to a specific user (a person registered in advance). In such an authentication system, the card reader 5 and the multi-function device 7 are communicably connected to the management server 2 (database server). Then, information related to the print contents printed by the MFP 7 (image data corresponding to the original of the print, a serial number unique to the data, a title of the data, a print date, etc.) Are associated with each identifier M1 permitted to be managed by the management server 2. This makes it possible to accurately grasp who printed what and when (print history of each person). In other words, even if a document related to confidential information is illegally printed, it is immediately obvious who has leaked which information. It will be possible to suppress. In general, the easy identification of the criminal also leads to prevention of fraud (in this case, the leakage of confidential information).

  (2) The card reader 5 (data reading device) is used as a data reading device that not only reads information stored in the IC card MC (storage medium) but also rewrites the IC card MC together with the identifier M1. The residual value data M2 indicating the degree of payment ability was stored. Then, based on the fact that the IC card MC is presented to be communicable to the card reader 5 as the data reading device, the consideration relating to the use of the multifunction device 7 is collected from the residual value data M2 (residual value). The data M2 is rewritten). According to such a configuration, a highly convenient and efficient collection of charges is performed by the portable storage medium (IC card MC).

  (3) Since the remaining value data M2 is associated with each identifier M1 and managed by the management server 2 together with the information relating to the print contents, no consideration is left on any IC card. It is possible to accurately grasp whether or not (remaining value information of each person).

  (4) A required number (usually many) of the card readers 5 are provided in the local area network together with the multifunction machine 7 and the like that together form a printing terminal, and a local area network (LAN) is constructed by these devices. As a result, a system for collecting and authenticating consideration for use related to each printing device (multifunction device 7) in the network can be easily and accurately constructed.

  (5) The identifier M1 stored in the IC card MC is handled in the management server 2 as indicating the identity of the owner. This facilitates management of information in the database.

  (6) Since a password is set for each IC card MC (identifier M1), the use other than the user is prohibited, and as a result, illegal use due to theft is prevented.

  (7) As the IC card MC, a non-contact type IC (integrated circuit) card that wirelessly communicates with the card reader 5 in a non-contact manner is adopted. This eliminates the trouble of inserting / removing the IC card MC in the card reader 5 and the concern about the removal trouble due to forgetting to remove the card MC or the failure of the device, thereby improving the convenience of the entire system and improving the convenience of the IC card MC. It will also prevent theft.

The embodiment described above may be modified as follows.
-The authentication of the identifier M1 stored in the IC card MC prohibits the use of a specific media holder (for example, disables the use of an IC card MC that has been stolen) or processes it to a specific media owner (For example, restricting the authority of students more than the teacher), or exempting the collection of fees for specific media owners.

  In the multifunction device 7, since the type of printing can be selected, authentication may be performed only for a specific type of printing. Further, the authentication by the password is not an essential configuration, and the authentication may be performed only by the approval of the identifier M1.

-Such a system can be used not only in schools but also in many facilities such as companies.
In the above-described embodiment, the above-described authentication is performed for the multifunction machine 7 having both printing functions as a printer, a copier (copy machine), and a scanner. However, the above-described authentication may be performed for a single printing device such as a single printer, a single copying machine, a single scanner, or the like, without being limited to the multifunction machine 7.

  -The remaining value data M2 stored in the IC card can be used for all types of electronic money compatible models in addition to electronic money indicating the degree of payment ability only for devices in the local area network. Points that are exclusive consideration that can be used only for predetermined printing devices that are associated in advance, such as multi-purpose electronic money, trains, buses, taxi tickets, etc. (that is, they cannot be used for other than printing devices) Money etc. can be used. It is also possible to use these together (store multiple types of residual value information in a single storage medium).

  -In addition, the above-described authentication is possible even in a configuration that does not collect compensation. In this case, the card reader 5 (data reading device) is not limited to a data reading / writing device that reads and rewrites, but only needs to read at least the information stored in the IC card MC (storage medium).

  In the above embodiment, a non-contact type IC (integrated circuit) card that performs wireless communication with the card reader 5 in a non-contact manner is employed as the IC card MC. However, it is sufficient for such a storage medium to be able to communicate with the card reader 5 so that data can be exchanged between them (data communication). The above-described authentication is possible even for a storage medium of a type (contact type) that can be attached to and detached from the window).

  Further, the shape of the storage medium is arbitrary, and for example, instead of the IC card MC, a rod-shaped (stick shape) storage medium or the like can be appropriately employed. Further, it may be incorporated in a key, key holder, seal or the like. In short, any portable storage medium (portable storage medium) may be used.
