In the print request screen shown in FIG. 7, an input field for inputting a user ID and a password of a user who wants to use the print service, a shooting button, and a print button are displayed. Further, in the vicinity of the shooting button, as a method for the information processing terminal 3 to acquire the MFP information of the MFP 1 in this service, the image displayed on the MFP 1 is imaged by the imaging unit 33 of the information processing terminal 3. An explanation to that effect is displayed.

  FIG. 8 is a schematic diagram illustrating an example of a code pattern of multifunction machine information. The code pattern of the multifunction machine information is obtained by coding multifunction machine information (device information) necessary for specifying the multifunction machine 1, and is a barcode, a QR code (registered trademark), or the like. In the first embodiment, the MFP information is the MFP ID assigned to the MFP 1. In addition to the MFP ID, information that can identify the MFP 1 can be used as the MFP information, such as a name given to the MFP 1 and information on the installation location (convenience store) of the MFP 1. Any one or more of these pieces of information can be used. The code pattern may be displayed on the operation panel 11 (display unit 11b) of the multi function device 1, or may be printed on paper or the like and attached to an appropriate position on the multi function device 1.

  The user operates the operation panel 32 of the information processing terminal 3, inputs his / her user ID and password, and the control unit (instructor information acquisition unit) 30 is connected to the user via the operation panel 32 (input unit 32a). An ID and a password (instructor information for specifying the instructor) are acquired. Next, the user operates the shooting button, and the control unit (apparatus information acquisition unit) 30 switches to the imaging mode by the imaging unit 33, captures a code pattern as shown in FIG. ) To get. After photographing the code pattern, the user operates the print button and requests the authentication server 2 to execute printing by a desired multifunction device 1. The control unit 30 of the information processing terminal 3 transmits the acquired code pattern information, user ID and password (hereinafter collectively referred to as authentication information) to the authentication server 2 via the communication unit (sending unit) 34 ( S2).

The control unit 20 of the authentication server 2 acquires code pattern information and authentication information via the communication unit (device information acquisition unit, user information acquisition unit) 22. And the user authentication part (authentication part) 26 performs an authentication process based on the acquired authentication information (S3). Based on whether or not the acquired authentication information is registered in the user information DB 21c, the user authentication unit 26 determines (authenticates) whether or not the user has already been registered as an appropriate user (S4). When the user is not authenticated (S4: NO), that is, when the user is not an appropriate user, the control unit 20 notifies the information processing terminal 3 via the communication unit 22 of an authentication error indicating that the authentication has failed. (S5). In this case, the control unit 20 of the authentication server 2 discards the code pattern information and the authentication information acquired from the information processing terminal 3.
In the information processing terminal 3 notified of the authentication error, the control unit 30 displays, for example, the authentication error on the operation panel 32 (S6) and ends the process.

When the user is authenticated (S4: YES), that is, when the user is an appropriate user, the control unit 20 of the authentication server 2 decodes the code pattern information acquired from the information processing terminal 3 (S7), and combines Acquire machine information (multifunction machine ID). Then, based on the MFP information obtained by decryption and the registration information in the MFP information DB 21b, the MFP management unit (identification unit) 25 specifies the destination information (IP address) of the MFP 1 ( S8). The control unit 20 of the authentication server 2 determines whether or not the multifunction device management unit 25 has identified the destination information of the multifunction device 1 (S9). Control is performed when the destination information of the multifunction device 1 cannot be specified (S9: NO), that is, when the acquired multifunction device information is not registered in the multifunction device information DB 21b, or when the code pattern cannot be decoded. The unit 20 notifies the information processing terminal 3 of a specific error indicating that the specification of the destination information of the multifunction device 1 has failed (S10). In this case, the control unit 20 of the authentication server 2 discards the code pattern information and the authentication information acquired from the information processing terminal 3.
In the information processing terminal 3 notified of the specific error, the control unit 30 displays the specific error on the operation panel 32, for example (S11), and ends the process.

  When the destination information of the MFP 1 can be identified (S9: YES), the control unit 20 of the authentication server 2 prints the electronic data DB 21a stored in association with the user (user ID) authenticated in step S3. The storage data is read by the storage processing unit 24. Then, the control unit (permission unit) 20 transmits the printing data read from the electronic data DB 21a to the multifunction device 1 based on the destination information specified in step S8 (S12), and print processing is performed to the multifunction device 1. Is instructed to execute. As a result, it is possible to execute the printing process instructed by the user using the information processing terminal 3.

The control unit 10 of the multifunction device 1 acquires print data via the communication unit 14, and the image forming unit 13 outputs an image based on the acquired print data (S13). As a result, the authenticated user can use the multifunction device 1, and the printing process instructed to the multifunction device 1 by the authenticated user is executed.
After the end of image output, the control unit 10 of the multifunction device 1 notifies the processing result to the authentication server 2 from the communication unit 14 (S14). The control unit 20 of the authentication server 2 notified of the processing result notifies the information processing terminal 3 of the processing result by the multifunction machine 1 from the communication unit 22 (S15). The control unit 30 of the information processing terminal 3 displays the notified processing result on, for example, the operation panel 32 (S16), and notifies the user of the information processing terminal 3 of the information. Thereby, the user who has instructed execution of the printing process (image output) by the multifunction device 1 using the information processing terminal 3 can know whether or not the printing process has been properly completed.

  As described above, in the image output system according to the first embodiment, when the user requests use authorization (user authentication) of the multifunction device 1 from the authentication server 2 using the information processing terminal 3, the multifunction device 1. There is no need to know the destination information in advance. In addition, since the user can easily acquire the multifunction machine information of the multifunction machine 1 by photographing the code pattern displayed (or pasted) on the multifunction machine 1 by the imaging unit 33 of the information processing terminal 3, the user can easily compose the multifunction machine. Machine 1 can be used.

  In addition, when the user transmits user information (user ID and password) to the authentication server 2, the code pattern information (multifunction device information) captured using the information processing terminal 3 is also transmitted to the authentication server 2. Information and multifunction peripheral information can be easily associated. Further, since the user can make a print request simultaneously with the authentication request, the operability when logging in to the authentication server 2 is improved. With this configuration, for example, even when printing is performed using the multifunction device 1 (public printer) installed in a convenience store that is used for the first time, it takes time to operate the multifunction device 1. The printed matter can be obtained quickly.

  Further, since information with low sensitivity such as information related to the MFP ID, the name of the MFP 1, and information regarding the installation location of the MFP 1 is used as the MFP information, the MFP transmitted from the information processing terminal 3 to the authentication server 2 is used. The information does not include network identification information such as the host name, IP address, and MAC address of the multifunction machine 1. Accordingly, since confidential information such as network identification information is not transmitted over the network, unauthorized acquisition of confidential information can be prevented and security risk can be reduced.

  Note that destination information (network identification information) of the multifunction device 1 may be included in the multifunction device information. In this case, since the authentication server 2 can acquire the destination information of the multifunction device 1 from information (image data) obtained by the information processing terminal 3 photographing the code pattern, the destination information of the multifunction device 1 is managed in advance. There is no need to keep it. Since the multifunction device information is displayed (or pasted) in the form of a code pattern in the multifunction device 1, confidential information such as network identification information is not included even if the multifunction device information includes the destination information of the multifunction device 1. Inadvertent leakage is suppressed and security can be maintained.

When generating the code pattern, the multifunction device 1 generates a code pattern by coding not only the multifunction device information (for example, the multifunction device ID) but also the printing conditions set by the user.
Specifically, a user who wants to use the multifunction device 1 operates the operation panel 11 of the multifunction device 1 to set desired printing conditions. For example, a “code pattern generation” button (not shown) displayed on the operation panel 11 is displayed. )). When the code pattern generation button is operated, the control unit 10 of the multifunction device 1 codes predetermined multifunction device information and the printing conditions set by the user, and displays the generated code pattern on the operation panel 11 (display unit 11b). ) To notify (present) the user. The printing conditions are setting conditions relating to processing that can be executed by the multifunction device 1 such as N-up printing, color printing, and monochrome printing.

  Note that the user inputs the user information (authentication information) via the print request screen (see FIG. 7) and the code pattern displayed on the multifunction device 1 is imaged by the imaging unit 33 of the information processing terminal 3.

Further, the authentication server 2 performs the user authentication based on the user information acquired from the information processing terminal 3 as in the first embodiment.

FIG. 9 is a flowchart illustrating a procedure of code pattern generation processing by the multifunction machine 1 according to the second embodiment.
A user who uses the print service operates the operation panel 11 of the multifunction machine 1 to set desired printing conditions. The control unit 10 of the multifunction device 1 receives the printing conditions set by the user via the operation panel 11 (S21). For example, the control unit 10 determines whether or not a predetermined button such as a code pattern generation button has been operated by the user (S22). If the predetermined button has not been operated (S22: NO), for example, a cancel button is displayed. If operated, the process is terminated.

  When the predetermined button is operated (S22: YES), the control unit 10 encodes the predetermined multifunction machine information (multifunction machine ID) and the accepted printing conditions, and generates a code pattern (S23). And the control part 10 displays the produced | generated code pattern on the operation panel 11 (S24), and complete | finishes a process. Note that predetermined multifunction machine information, that is, multifunction machine information for each multifunction machine 1 is stored in advance in a storage unit (not shown). The method for generating the code pattern is not particularly limited, and any method may be used.

FIG. 10 is a flowchart illustrating the procedure of a printing process performed by the image output system according to the second embodiment. Also in FIG. 10, the processing on the left side indicates processing by the multifunction device 1, the center processing indicates processing by the authentication server 2, and the processing on the right side indicates processing by the information processing terminal 3.
In the image output system of the second embodiment, the authentication server 2 and the information processing terminal 3 perform the same processes as steps S1 to S11 in the flowchart shown in FIG. In step S9, when the MFP management unit 25 of the authentication server 2 can identify the destination information of the MFP 1 based on the MFP information (S9: YES), the control unit 20 of the authentication server 2 performs step S7. The printing conditions are specified from the information obtained by decrypting (S31). In the second embodiment, the MFP information and the printing conditions are included in the code pattern. Therefore, when the control unit 20 of the authentication server 2 decrypts the code pattern in step S7, the MFP information and the printing conditions. And you can get

  The control unit 20 of the authentication server 2 reads out the printing data stored in the electronic data DB 21a in association with the user (user ID) authenticated in step S3 by the storage processing unit 24. Then, the control unit 20 transmits the printing data read from the electronic data DB 21a to the multifunction device 1 based on the destination information specified in step S8 (S12). At this time, the control unit 20 transmits an instruction to execute the printing process under the printing conditions specified in step S31 together with the printing data to the multifunction device 1. As a result, the printing process can be executed under the conditions set by the user.

  The control unit 10 of the MFP 1 acquires printing data and printing conditions via the communication unit 14, and the image forming unit 13 performs printing processing (images under the acquired printing conditions for the acquired printing data. Output) (S13). Thereafter, the multifunction machine 1, the authentication server 2, and the information processing terminal 3 perform the same processing as steps S14 to S16 in the flowchart shown in FIG.

  As described above, in the image output system according to the second embodiment, the code pattern information transmitted from the information processing terminal 3 to the authentication server 2 includes not only the MFP information but also the printing conditions. Therefore, the user can instruct execution of printing processing under desired printing conditions by photographing the code pattern of the multifunction device 1 with the imaging unit 33 of the information processing terminal 3 and transmitting it to the authentication server 2. In the conventional apparatus, for example, a user displays a predetermined print condition setting screen on the information processing terminal 3, inputs a desired print condition to the information processing terminal 3, and the information processing terminal 3 is input. The print condition is transmitted to the authentication server 2. However, in the second embodiment, the user operates the operation panel 11 of the multifunction device 1 to set the printing conditions, the code pattern including the set printing conditions is photographed by the information processing terminal 3, and the obtained information is displayed. By transmitting to the authentication server 2, desired printing conditions can be transmitted to the authentication server 2. Therefore, since the user only has to operate the multifunction device 1, the burden of the printing condition setting operation can be reduced.

  In the second embodiment, the configuration in which the multifunction device 1 encodes the multifunction device information and the printing conditions has been described as an example. However, the multifunction device 1 according to the first embodiment described above includes a configuration in which the multifunction device information is encoded. May be.

The authentication server 2 according to the second embodiment transmits an execution instruction for print processing under the printing conditions (printing conditions set by the user operating the multifunction device 1) acquired from the information processing terminal 3 to the multifunction device 1. Although it is a structure, it is not limited to such a structure.
For example, the authentication server 2 manages printing conditions relating to print processing that can be actually executed by each multifunction device 1 based on the multifunction device information DB 21b (see FIG. 4). Accordingly, the authentication server 2 may be configured to specify the printing conditions that are actually instructed to the multifunction device 1 based on the printing conditions acquired from the information processing terminal 3 and the registration information in the multifunction device information DB 21b.

  Specifically, the control unit (device condition specifying unit) 20 of the authentication server 2 and the printing conditions included in the information acquired from the information processing terminal 3 and the printing conditions registered in the multifunction device information DB 21b (available for use). It is determined whether or not (setting) matches. If they match, the control unit 20 specifies the printing conditions included in the information acquired from the information processing terminal 3 as the printing conditions that are actually instructed to the multifunction device 1. If they do not match, for example, if the printing condition acquired from the information processing terminal 3 is execution of color printing and the printing condition registered in the MFP information DB 21b is execution of monochrome printing, the control unit 20 Execution of printing is specified as a printing condition that is actually instructed to the multifunction device 1. Then, the control unit 20 transmits to the multifunction device 1 an instruction to execute the printing process under the specified printing conditions together with the printing data. Thus, for example, even when a printing condition that cannot be actually executed by the multifunction device 1 is transmitted from the information processing terminal 3, the authentication server 2 changes the printing condition to be actually executable by the multifunction device 1. Thus, the print processing execution instruction is transmitted to the multi function device 1, so that the print processing can be executed reliably.

  Further, the authentication server 2 manages printing conditions (usable settings) that are permitted for each user based on the user information DB 21c (see FIG. 4). Therefore, the authentication server 2 may be configured to specify the printing conditions that are actually instructed to the multifunction machine 1 based on the printing conditions acquired from the information processing terminal 3 and the registration information in the user information DB 21c.

  Specifically, the control unit (user condition specifying unit) 20 of the authentication server 2 prints the printing conditions included in the information acquired from the information processing terminal 3 and the printing registered in the user information DB 21c for this user. It is determined whether or not the conditions match. If they match, that is, if the printing conditions requested by the user are the printing conditions permitted for the user, the control unit 20 sets the printing conditions included in the information acquired from the information processing terminal 3. The printing conditions that are actually instructed to the multifunction device 1 are specified. If they do not match, for example, if the printing condition requested by the user is N-up printing, and the printing condition permitted for this user is 1-up printing, the control unit 20 sets the 1-up printing. Execution of printing is specified as a printing condition that is actually instructed to the multifunction device 1. Then, the control unit 20 transmits to the multifunction device 1 an instruction to execute the printing process under the specified printing conditions together with the printing data. Thereby, the print conditions that can be executed for each user can be limited, and the print processing can be reliably executed under the print conditions permitted for each user.

(Embodiment 3)
The image output system according to the third embodiment will be described below. Since the image output system of the third embodiment is realized by the same configuration as the image output system of the second embodiment described above, the same components are denoted by the same reference numerals and detailed description thereof is omitted.

The image output system according to the third embodiment is configured such that the multifunction device 1 generates a code pattern of its own multifunction device information. When generating the code pattern, not only the multifunction device information (for example, the multifunction device ID) The code pattern is generated including the state information (status information) related to the operation state of the multifunction device 1.
Specifically, the control unit 10 of the multifunction device 1 monitors the operation state of the multifunction device 1 itself. For example, if there is some error such as out of ink, N-up printing cannot be performed, or a paper jam has occurred. The occurrence is monitored. When any error occurs, the control unit 10 encodes predetermined MFP information and information indicating the generated error, and displays the code pattern on the operation panel 11 (display unit 11b) to notify the user (presentation). )

FIG. 11 is a flowchart illustrating a procedure of code pattern generation processing by the multifunction machine 1 according to the third embodiment.
The control unit 10 of the multifunction device 1 determines whether any error has occurred in its multifunction device 1 (S41), and if no error has occurred (S41: NO), until an error occurs. , Perform other processing and wait.

  When an error occurs (S41: YES), the control unit 10 of the multifunction device 1 encodes predetermined multifunction device information (multifunction device ID) and information indicating the generated error, and generates a code pattern (S42). And the control part 10 displays the produced | generated code pattern on the operation panel 11 (S43), and complete | finishes a process. Note that predetermined multifunction machine information and information indicating an error are stored in advance in a storage unit (not shown).

FIG. 12 is a flowchart illustrating the procedure of a printing process performed by the image output system according to the third embodiment. Also in FIG. 12, the processing on the left side indicates processing by the multifunction device 1, the center processing indicates processing by the authentication server 2, and the processing on the right side indicates processing by the information processing terminal 3.
In the image output system of the third embodiment, the authentication server 2 and the information processing terminal 3 perform the same processing as steps S1 to S11 in the flowchart shown in FIG. If the MFP management unit 25 of the authentication server 2 can identify the destination information of the MFP 1 based on the MFP information (S9: YES) in step S9, the control unit (determination unit) 20 of the authentication server 2 Determines whether or not an error has occurred in the multifunction device 1 based on the information obtained by decoding in step S7 (S51). In the third embodiment, since the MFP information and information indicating an error are included in the code pattern, the control unit 20 of the authentication server 2 receives the MFP information and the information when the code pattern is decoded in step S7. Information indicating an error can be obtained.

  When the control unit 20 of the authentication server 2 determines that no error has occurred in the multifunction machine 1 (S51: NO), the control unit 20 performs the same process as step S12 in the flowchart shown in FIG. Thereafter, the multifunction device 1, the authentication server 2, and the information processing terminal 3 perform the same processing as steps S13 to S16 in the flowchart shown in FIG.

  On the other hand, if it is determined that an error has occurred in the multifunction device 1 (S51: YES), the control unit 20 of the authentication server 2 notifies the information processing terminal from the communication unit 22 that an error has occurred in the multifunction device 1. 3 is notified (S52). In the information processing terminal 3 notified of the occurrence of the error, the control unit 30 displays, for example, on the operation panel 32 that an error has occurred in the multifunction device 1 (S53), notifies the user, and ends the process. . Thereby, a user who has instructed execution of printing processing (image output) by the multifunction device 1 using the information processing terminal 3 can grasp that the multifunction device 1 has an error and cannot use the multifunction device 1. Note that the control unit 20 of the authentication server 2 may also notify the information processing terminal 3 of the type of error that has occurred in the multifunction device 1.

As described above, in the image output system according to the third embodiment, the information transmitted from the information processing terminal 3 to the authentication server 2 includes the status information of the multifunction device 1, so that the authentication server 2 is connected to the information processing terminal 3. It is possible to grasp that an error has occurred in the multi-function device 1 at the time when an authentication request and a print request are made.
In the conventional system, the authentication server 2 instructs the multifunction device 1 to execute print processing, and grasps the occurrence of an error in the multifunction device 1 only when printing failure is notified from the multifunction device 1 in response to this instruction. could not. However, in the third embodiment, since the authentication server 2 can grasp the occurrence of an error in the multifunction device 1 at the time when the information acquired from the information processing terminal 3 is decrypted, it can be grasped early and the action for the error can be quickly performed. be able to.

In the third embodiment, when the authentication server 2 detects that an error has occurred in the multifunction device 1, the authentication server 2 interrupts the printing process by the multifunction device 1 and indicates that an error has occurred in the multifunction device 1. In this configuration, the information processing terminal 3 (user) is notified. In addition to such a configuration, for example, if there is a print process that can be executed by the multifunction device 1 even if an error has occurred in the multifunction device 1, an authentication server is instructed to instruct the multifunction device 1 to execute the printing process. 2 may be configured.
Specifically, the authentication server 2 determines the operation state of the multifunction device 1 based on the status information acquired from the information processing terminal 3. If the multifunction device 1 is out of color ink, the authentication server 2 stores the information in the multifunction device information DB 21b. Based on the registration information, it is determined whether or not the multifunction device 1 is capable of monochrome printing. If monochrome printing is possible, the authentication server 2 transmits a monochrome printing execution instruction to the multifunction device 1. As a result, even when an error has occurred in the multifunction device 1, it is possible to perform printing processing under printing conditions that can be executed by the multifunction device 1.

  In the third embodiment, the information processing terminal 3 transmits information obtained by imaging the code pattern to the authentication server 2, and the authentication server 2 decrypts the acquired information to decode the multifunction machine information and the multifunction machine 1. It was the structure which acquires state information. In addition to such a configuration, the information processing terminal 3 may have a decoding function and may decode the information obtained by photographing the code pattern. In this case, when the control unit 30 of the information processing terminal 3 decodes the code pattern, it can determine whether or not an error has occurred in the multifunction device 1 based on the state information obtained by decoding. Therefore, it is possible to detect errors and take measures for errors at an earlier stage. In this case, the information processing terminal 3 only has to transmit the decrypted MFP information and status information to the authentication server 2. In such a configuration, the processing load on the authentication server 2 can be reduced.

  Further, when the authentication server 2 detects that an error has occurred in the multifunction device 1, for example, a configuration in which an error occurrence is notified to a terminal carried by a serviceman managing the multifunction device 1 is authenticated. The server 2 may be further provided.

(Embodiment 4)
The image output system according to the fourth embodiment will be described below. Since the image output system of the fourth embodiment is realized by the same configuration as the image output systems of the first to third embodiments described above, the same reference numerals are given to the same configurations, and detailed description thereof is omitted.
In the image output systems of Embodiments 1 to 3 described above, the user has to perform user registration for the print service in advance. In the image output system of the fourth embodiment, even the user who is not registered as a user can use the multifunction device 1.

  For example, the MFP 1 of the fourth embodiment displays a “trial print” button (not shown) on the operation panel 11. When a user who has not registered as a user wants to use the multifunction machine 1, the user operates the trial print button displayed on the operation panel 11. When the trial print button is operated, the control unit 10 of the multifunction device 1 encodes and generates predetermined multifunction device information (multifunction device ID) and permission information for temporarily permitting the use of the multifunction device 1. The code pattern is displayed on the operation panel 11 (display unit 11b) and notified (presented) to the user.

FIG. 13 is a flowchart illustrating a procedure of code pattern generation processing by the multifunction machine 1 according to the fourth embodiment.
The control unit 10 of the multifunction device 1 determines whether or not the trial print button on the operation panel 11 has been operated by the user (S61). If the trial print button has not been operated (S61: NO), Wait until the trial print button is operated and perform other processing.

  When the trial print button is operated (S61: YES), the control unit 10 encodes predetermined multifunction machine information (multifunction machine ID) and permission information, and generates a code pattern (S62). And the control part 10 displays the produced | generated code pattern on the operation panel 11 (S63), and complete | finishes a process. The predetermined multifunction machine information and permission information are stored in advance in a storage unit (not shown).

FIG. 14 is a flowchart illustrating the procedure of a printing process performed by the image output system according to the fourth embodiment. Also in FIG. 14, the processing on the left side indicates processing by the multifunction device 1, the center processing indicates processing by the authentication server 2, and the processing on the right side indicates processing by the information processing terminal 3.
In the image output system according to the fourth embodiment, a user who has not registered as a user but wants to use the print service uses the information processing terminal 3 to access the authentication server 2 that provides the print service. Then, the information processing terminal 3 acquires a predetermined web page from the authentication server 2, and displays a print request screen on the display unit 32b based on the acquired web page (S71).

FIG. 15 is a schematic diagram illustrating a configuration example of a print request screen. In the print request screen shown in FIG. 15, in addition to the input field for inputting the user ID and password of the user who wants to use the print service, the shooting button, and the print button, “use trial print” is selected. A check box is displayed.
A user who has not registered as a user operates the operation panel 32 of the information processing terminal 3 instead of inputting the user ID and password, and checks the check box “Use trial print”.

On the other hand, the user operates the trial print button of the multifunction device 1 and displays a code pattern in which the multifunction device ID and permission information are coded on the operation panel 11 of the multifunction device 1. Then, the user operates the shooting button on the print request screen, and the control unit 30 of the information processing terminal 3 captures the code pattern being displayed on the multi-function device 1 by the imaging unit 33, and the code pattern information (image data). To get. After photographing the code pattern, the user operates the print button and requests the authentication server 2 to execute printing by a desired multifunction device 1.
When the “Use trial print” check box is checked on the print request screen, the control unit 30 of the information processing terminal 3 does not wait for input of the user ID and password, and only acquires the acquired code pattern information. Is transmitted to the authentication server 2 via the communication unit 34 (S72).

When only the code pattern information is acquired via the communication unit 22, the control unit 20 of the authentication server 2 decrypts the acquired code pattern information (S73), and obtains the MFP information (multifunction machine ID) and permission information. get. The control unit 20 determines whether or not the permission information is included in the information obtained by decryption (S74). If it is determined that the permission information is not included (S74: NO), the control unit 20 The information processing terminal 3 is notified via the communication unit 22 that use cannot be permitted (S75). In this case, the control unit 20 of the authentication server 2 discards the code pattern information acquired from the information processing terminal 3.
In the information processing terminal 3 that is notified that the use of the multifunction device 1 cannot be permitted, the control unit 30 displays that fact on the operation panel 32 (S76), and ends the process.

  When permission information is included in the information obtained by decryption (S74: YES), the control unit 20 (multifunction device management unit 25) of the authentication server 2 and the multifunction device information obtained by decryption and the composite Based on the registration information in the machine information DB 21b, the destination information (IP address) of the multifunction machine 1 is specified (S8). Thereafter, the multifunction device 1, the authentication server 2, and the information processing terminal 3 perform the same processing as steps S9 to S16 in the flowcharts shown in FIGS.

As described above, in the image output system according to the fourth embodiment, a temporary use authority can be given to a user who is not registered in the print service and does not have the use authority for the multifunction machine 1. Therefore, it is possible to try the print service provided by the image output system.
Further, a temporary user ID and password may be given to a user who has requested the use of the multifunction device 1 by the above-described processing, and not only a single printing process but also a right to use for a certain period may be given.

  In the first to fourth embodiments, the authentication server 2 may further include a configuration in which the MFP information and user information (authentication information) acquired from the information processing terminal 3 are held in a storage unit (not shown). In this case, in the storage unit, the MFP information and the user information can be managed as log information, and the stored information can be analyzed. Further, the authentication server 2 can execute billing processing according to the usage status of the image output apparatus, usage status analysis processing for the image output apparatus, and the like.

In the image output systems of Embodiments 1 to 4, since the user registers printing data in the authentication server 2 in advance, the user actually makes an authentication request (print instruction) to the authentication server 2 using the information processing terminal 3. In this case, only the code pattern information and the authentication information of the MFP information need be transmitted to the authentication server 2. Therefore, in Embodiments 1 to 4, it is not necessary to store print data in the information processing terminal 3, and the amount of data transmitted from the information processing terminal 3 to the authentication server 2 can be reduced.
In addition to such a configuration, when the user makes an authentication request (print instruction) to the authentication server 2 using the information processing terminal 3, the print data is transmitted to the authentication server 2 together with the code pattern information and the authentication information. You may make it do. In this case, since it is not necessary for the authentication server 2 to manage print data for each user, the processing load on the authentication server 2 can be reduced.

  In the first to third embodiments, when the user makes an authentication request (print instruction) to the authentication server 2 using the information processing terminal 3, the code pattern information and the authentication information are simultaneously transmitted from the information processing terminal 3 to the authentication server 2. The configuration was sent. In addition to such a configuration, for example, when only the authentication information is first transmitted from the information processing terminal 3 to the authentication server 2 and the user is authenticated as a result of the authentication processing by the authentication server 2, the authentication is performed from the information processing terminal 3. A configuration in which code pattern information is transmitted to the server 2 may also be used. Further, when the user makes an authentication request, the print data is transmitted to the authentication server 2 together with the code pattern information and the authentication information. The code pattern information is transmitted to the authentication server 2 first, and the authentication server 2 When the MFP 1 can be identified by 2, print data may be transmitted from the information processing terminal 3 to the authentication server 2.

  The information processing terminal 3 according to the first to fourth embodiments acquires the multifunction machine information by photographing the code pattern by the imaging unit 33, but is not limited to this configuration. For example, when the code pattern of the multifunction device information is a barcode, the information processing terminal 3 includes a code reading unit such as a barcode reader instead of the imaging unit 33, and acquires the multifunction device information by the code reading unit. May be.

  In the image output systems of the first to fourth embodiments, the multifunction device 1 notifies the authentication server 2 of the processing result, so that the authentication server 2 can grasp the processing result of the multifunction device 1. Therefore, when notified of completion of the printing process, the authentication server 2 can, for example, delete the print data held in the authentication server 2 and grasp the use status of the multifunction device 1 of each user. In addition, when the processing result includes specific usage status of each user, for example, print processing contents such as output paper size, number of output paper sheets, execution of black and white printing or color printing, based on such information. Thus, billing processing for each user becomes possible.

  The information processing terminal 3 according to the first to fourth embodiments transmits information (image data) obtained by photographing a code pattern by the imaging unit 33 to the authentication server 2, and the authentication server 2 decodes the code pattern to decode the multifunction device. It was the composition which acquires information. In addition to such a configuration, the information processing terminal 3 has a decoding function, decodes information obtained by photographing a code pattern, acquires multifunction machine information, and acquires the obtained multifunction machine information as the authentication server 2. The structure which transmits to may be sufficient. In this case, the processing burden on the authentication server 2 can be reduced.

  In the information processing terminal 3 according to the first to third embodiments, the user operates the operation panel 32 on the print request screen and inputs authentication information (user ID and password). In addition to such a configuration, for example, when the information processing terminal 3 has an IC card reader, the user ID and password are stored in advance in the IC card, and the authentication information is read from the IC card by the IC card reader. Good.

  In the image output system of the present invention, in addition to the multifunction device 1, a printer having only a printer function, a display device for displaying an image, and the like can be used.
