[0050] In step Scd, the data management apparatus 300 transmits display data corresponding to the print data designated by the print data designation signal to the image forming apparatus 100. Specifically, the control unit 310 specifies the print data designated by the print data designation signal from the folders in the storage unit 320, and reads out the display data related to the specified print data. The communication unit 330 transmits the display data related to the print data to the image forming apparatus 100.

[0051] In step Spg, display data related to the print data designated by the print data designation signal is received.

[0059] In step Spl, the image forming apparatus 100 forms an image on a sheet according to the print data. Specifically, the forming unit 130 forms an image on a sheet according to the print data.

[0060] In the image forming apparatus 100 of the present embodiment, the display data related to the print data is divided into first display data and second display data and displayed. Therefore, regardless of the display screen of the display unit 150, it is possible to suppress the limitation of the display according to the display data related to the print data. That is, even if the display screen of the display unit 150 is a small screen that cannot display the display data at once, it is possible to avoid the display of the display data related to the print data being restricted.

[0061] Typically, since the display screen of the display unit 150 is relatively small, in the image forming apparatus 100 of the present embodiment, the display unit 150 displays the first display data and the second display data of the display data on separate screens. For example, the display unit 150 displays the first display data on the display screen and also displays a "proceed button" for transitioning to another display screen for displaying the second display data. When the operator operates the "proceed button", the display unit 150 displays the second display data on the display screen. Incidentally, when the display unit 150 displays the second display data on the display screen, it is preferable to display a "return button" for returning to the original display screen for displaying the first display data. Further, the operator may cause the display unit 150 of the image forming apparatus 100 to display display data other than the first and second display data by operating the operation unit 140.

[0062] Next, with reference to FIGS. 1 to 4, printing of print data in the image forming apparatus 100 will be described. FIGS. 4(a) to 4(d) are schematic views of the display unit 150 when downloading print data in the image forming apparatus 100.

[0063] As shown in FIG. 4(a), in the image forming apparatus 100, the display unit 150 has a display screen 152. The display unit 150 displays the hierarchical structure of the folders in the storage unit 320 according to the hierarchical structure display signal. Further, the display unit 150 displays a return button R for returning the display screen 152 to the previous screen. The return button R is located at the lower right of the display screen 152.

[0064] The display unit 150 displays the hierarchical structure of the folders according to the hierarchical structure display signal. Here, the folders, folder A, folder B, and folder C are managed in the same layer. The operator can select folder A, folder B, and folder folder C using the operation unit 140.

[0065] As shown in FIG. 4(b), when the operation unit 140 receives an operation of an operator who selects a folder, the display unit 150 displays files or folders in the selected folder. For example, while the display unit 150 is displaying the hierarchical structure of folders, when the operation unit 140 receives an operation of an operator who selects folder A, the display unit 150 displays file A and file B included in the selected folder A. The operation unit 140 receives an operation of an operator who selects file A and file B.

[0066] As described above, when file A and file B are selected, the communication unit 160 transmits a print data designation signal designating the selected files to the data management device 300. Thereafter, the communication unit 160 receives display data related to the selected files from the data management device 300. The display unit 150 displays according to the display data.

[0067] When the operation unit 140 receives an operation of an operator who selects a file, transmits a print data designation signal to the data management device 300, and the communication unit 160 receives the above display data from the data management device 300, as shown in FIG. 4(c), the display unit 150 displays first display data related to the file according to the display data. Here, the first display data indicates print conditions. The display unit 150 displays the print conditions according to the first display data. The print conditions include the number of printed sheets, the size of the paper at the time of printing, the type of paper, the necessity of layout change, and print setting conditions (single-sided printing, double-sided printing).

[0068] A return button R is located at the lower right of the display screen 152. The return button R is a button for returning to the previous display screen. When the return button R is operated, the display screen transitions to the previous display screen.

[0069] A forward button F is located at the lower left of the display screen 152. The forward button F is a button for advancing to the next display screen. When the forward button F is operated, the display screen transitions to the next display screen.

[0070] When the "Advance" button F is operated, as shown in FIG. 4(d), the display unit 150 displays the second display data as the next display screen. The display unit 150 displays the deadline for the print data.

[0071] The "Advance" button F is located at the lower left of the display screen 152. The "Advance" button F is a button for advancing to the next display screen. When the "Advance" button F is operated, the display screen transitions to the next display screen.

[0072] The "Return" button R is located at the lower right of the display screen 152. In this case, the "Return" button R is a button for returning to the previous display screen. When the "Return" button R is operated, the display screen transitions to the previous display screen.

[0073] As described above, in the image forming apparatus 100 of the present embodiment, the first display data and the second display data can be switched and displayed on the display screen 152 by operating the "Advance" button or the "Return" button. Therefore, even if the display screen 152 of the display unit 150 is relatively small, the display unit 150 can display a large amount of display data.

[0074] When the display screen is relatively large, it is preferable that a plurality of data included in the display data are displayed on one display screen.

Also, although the data communication system 10 shown in FIGS. 14 and 15 includes a plurality of information processing terminals 200 in addition to the plurality of image forming apparatuses 100, the functions of the plurality of information processing terminals 200 do not have to be equal.

[0182] Next, with reference to FIGS. 1 to 16, the data communication system 10 of the present embodiment will be described. FIG. 16 is a schematic diagram of the data communication system 10. The data communication system 10 in FIG. 16 has the same configuration as the data communication system 10 shown in FIGS. 10 to 15, except that the functions of the image forming apparatus 100 and the information processing terminal 200 are different, and redundant explanations will be omitted for the purpose of avoiding redundancy.

[0183] As shown in FIG. 16, the data communication system 10 of the present embodiment includes a plurality of image forming apparatuses 100. The plurality of image forming apparatuses 100 includes image forming apparatuses 100a to 100c and an image forming apparatus 100t. The functions of the image forming apparatuses 100a to 100c are equal to each other. On the other hand, the function of the image forming apparatus 100t is different from the functions of the image forming apparatuses 100a to 100c. The image forming apparatus 100t has functions not permitted for the image forming apparatuses 100a to 100c.

[0184] Note that the data communication system 10 of the embodiment may include a plurality of information processing terminals 200 that operate in cooperation with the plurality of image forming apparatuses 100. The plurality of information processing terminals 200 includes information processing terminals 200a to 200c and an information processing terminal 200t. The functions of the information processing terminals 200a to 200c are equal to each other. On the other hand, the function of the information processing terminal 200t is different from the functions of the information processing terminals 200a to 200c. The information processing terminal 200t has functions not permitted for the information processing terminals 200a to 200c.

[0185] For example, when the image forming apparatus 100t or the information processing terminal 200t uploads scan data to the data management apparatus 300, it may be possible to set print conditions for printing by downloading the scan data. On the other hand, the image forming apparatuses 100a to 100c or the information processing terminals 200a to 2 00c do not necessarily have to be able to set print conditions for printing by downloading scan data when uploading the scan data to the data management apparatus 300.

[0186] The data communication system 10 of the present embodiment is suitably used for distribution of tasks, collection of answers, evaluation of answers, and return of evaluation results. In this case, the image forming apparatus 100t and the information processing terminal 200t are suitably used by a task distributor who distributes tasks. For example, the task distributor includes an administrator, a teacher, an instructor.

[0187] The image forming apparatuses 100a to 100c and the information processing terminals 200a to 200c are suitably used by a respondent who answers a task. For example, the respondent includes a person to be managed, a pupil, a student.

[0188] Next, with reference to FIGS. 1 to 19, the data communication system 10 of the present embodiment will be described. FIGS. 17(a) to 19(b) are schematic diagrams for explaining upload of scan data and download of print data using a folder in the data communication system 10 of the present embodiment. Here, an operator of the image forming apparatus 100t and the information processing terminal 200t is referred to as operator T. Also, an operator of the image forming apparatus 100a and the information processing terminal 200a is referred to as operator A, an operator of the image forming apparatus 100b and the information processing terminal 200b is referred to as operator B, and an operator of the image forming apparatus 100c and the information processing terminal 200c is referred to as operator C.

[0189] As shown in FIG. 17(a), the image forming apparatus 100t scans the task sheet SS to generate task scan data SSD. Thereafter, the image forming apparatus 100t transmits the task scan data SSD to the data management apparatus 300.

[0190] The data management device 300 has a task folder and a submission folder as folders. The task folder is used for distributing the task sheet SS. The submission folder is used when submitting the response sheet RS with the answers written on the task sheet SS. The task folder and the submission folder may be created in the data management device 300 using the image forming apparatus 100t or the information processing terminal 200t.

[0191] The image forming apparatus 100t transmits the task scan data SSD to the data management device 300 together with folder designation information for designating the task folder. The image forming apparatus 100t or the information processing terminal 200t may set print conditions when downloading the task folder. The print conditions may be set by the operation of the image forming apparatus 100t by the operator T. Also, the print data deadline may be set by the operation of the image forming apparatus 100t, and the set print data deadline may be transmitted from the image forming apparatus 100t to the data management device 300. Further, the above-described print condition restriction information may be generated by the operation of the information processing terminal 200t, and the print condition restriction information may be transmitted from the information processing terminal 200t to the data management device 300.

[0192] The data management device 300 receives the task scan data SSD together with folder designation information for designating the task folder. The data management device 300 stores the task scan data SSD in the task folder having a hierarchical structure. Thereby, the task scan data SSD is uploaded to the task folder having a hierarchical structure in the data management device 300.

[0193] As shown in FIG. 17(b), the image forming apparatuses 100a to 100c read and receive the task scan data SSD from the task folder having a hierarchical structure in the data management device 300. Thereby, the task scan data SSD is downloaded from the task folder of the folder hierarchical structure of the data management device 300 to the image forming apparatuses 100a to 100c.

[0194] The image forming apparatus 100a forms an image according to the task scan data SSD on a sheet. From this, the image forming apparatus 100a can form the task sheet SSa.

[0195] Similarly, the image forming apparatus 100b and the image forming apparatus 100c form an image according to the task scan data SSD on a sheet. From this, the image forming apparatus 100b and the image forming apparatus 100c can form the task sheets SSb and SSc. Typically, the task sheets SSa to SSc of the image forming apparatuses 100a to 100c are the same.

[0196] Thereafter, typically, the operator A writes an answer on the task sheet SSa. As a result, the task sheet SSa becomes the answer sheet RSa.

[0197] Similarly, the operator B writes an answer on the task sheet SSb. As a result, the task sheet SSb becomes the answer sheet RSb. The operator C writes an answer on the task sheet SSc. As a result, the task sheet SSc becomes the answer sheet RSc.

[0198] As shown in Fig. 18(a), the image forming apparatus 100a generates answer scan data RSDa by scanning the answer sheet RSa and transmits it to the data management apparatus 300. At this time, the image forming apparatus 100a designates the submission folder in the hierarchical structure in the data management apparatus 300 that stores the answer scan data RSDa and transmits the answer scan data RSDa. As a result, the answer scan data RSDa is uploaded from the image forming apparatus 100a to the submission folder in the hierarchical structure in the data management apparatus 300.

[0199] Similarly, the image forming apparatus 100b generates answer scan data RSDb obtained by scanning the answer sheet RSb and transmits it to the data management apparatus 300. At this time, the image forming apparatus 100b designates the submission folder in the hierarchical structure in the data management apparatus 300 that stores the answer scan data RSDb and transmits the answer scan data RSDb. As a result, the answer scan data RSDb is uploaded from the image forming apparatus 100b to the submission folder in the hierarchical structure in the data management apparatus 300.

[0200] Similarly, the image forming apparatus 100c generates answer scan data RSDc obtained by scanning the answer sheet RSc and transmits it to the data management apparatus 300. At this time, the image forming apparatus 100c designates the submission folder in the hierarchical structure in the data management apparatus 300 that stores the answer scan data RSDc and transmits the answer scan data RSDc. As a result, the answer scan data RSDc is uploaded from the image forming apparatus 100c to the submission folder in the hierarchical structure in the data management apparatus 300.

[0201] As shown in FIG. 18(b), the image forming apparatus 100t reads out the answer scan data RSDa to RSDc from the submission folder in the data management apparatus 300 and forms an image on a sheet. As a result, the answer scan data RSDa to RSDc are downloaded from the submission folder of the folder hierarchical structure of the data management apparatus 300 to the image forming apparatus 100t. The image forming apparatus 100t forms an image corresponding to the answer scan data RSDa to RSDc on a sheet. From this, the image forming apparatus 100t can form the answer sheets RSa to RSc.

[0202] Note that the image forming apparatus 100t may extract and display only the data for which the date and time when each of the response scan data RSDa to RSDc was transmitted to the data management apparatus 300 is included in the time zone specified by the operator. Further, the image forming apparatus 100t may display the response scan data RSDa to RSDc excluding the data for which the scoring by the operator T described later has been completed. By these means as well, the data desired by the operator T can be preferentially displayed, so that the restriction of the display according to the display data related to the print data can be suppressed.

[0203] Thereafter, typically, the operator T writes an evaluation on the answer sheets RSa to RSc. For example, the operator T scores the answer sheets RSa to RSc. As a result, as shown in FIG. 19(a), the answer sheets RSa to RSc become the evaluation result sheets ESa to ESc.

[0204] The image forming apparatus 100t scans the evaluation result sheets ESa to ESc to generate evaluation result scan data ESDa to ESDc. Thereafter, as shown in FIG. 19(a), the image forming apparatus 100t transmits the evaluation result scan data ESDa to ESDc to the data management apparatus 300.

[0205] Here, the data management apparatus 300 has a return folder in addition to the task folder and the submission folder as folders. The return folder is used for returning the evaluation result sheets ESa to ESc. The return folder may be created in the data management apparatus 300 using the image forming apparatus 100t or the information processing terminal 200t.

[0206] The image forming apparatus 100t transmits the evaluation result scan data ESDa to ESDc to the data management apparatus 300 together with folder designation information designating the return folder.

[0207] The data management device 300 receives evaluation result scan data ESDa to ESDc together with folder designation information for designating a return folder. The data management device 300 stores the evaluation result scan data ESDa to ESDc in the return folder having a hierarchical structure. As a result, the evaluation result scan data ESDa to ESDc are uploaded to the return folder having the hierarchical structure in the data management device 300.

[0208] As shown in FIG. 19(b), the image forming apparatuses 100a to 100c read and receive the evaluation result scan data ESDa to ESDc from the return folder having the hierarchical structure in the data management device 300. As a result, the evaluation result scan data ESDa to ESDc are downloaded from the return folder of the folder hierarchical structure of the data management device 300 to the image forming apparatuses 100a to 100c.

[0209] The image forming apparatus 100a forms an image according to the evaluation result scan data ESDa on a sheet. Thus, the image forming apparatus 100a can form an evaluation result sheet ESa. Similarly, the image forming apparatuses 100b and 100c form images according to the evaluation result scan data ESDb and ESDc on a sheet. Thus, the image forming apparatuses 100b and 100c can form problem sheets ESb and ESc.

[0210] As described above, according to the present embodiment, distribution of problems, collection of answers, evaluation of answers, and transmission of evaluation results can be suitably executed.

[0211] In FIG. 17(b), the image forming apparatuses 100a to 100c download problem scan data SSD and form problem sheets SSa to SSc. In this case, the data management device 300 may check the image forming apparatuses 100a to 100c or the operators A to C that have downloaded the problem scan data SSD, and create a download list indicating the image forming apparatuses 100a to 100c or the operators A to C that have downloaded the problem scan data SSD.

[0212] Note that the download list is accessible from the image forming apparatus 100t and / or the information processing terminal 200t, and it is preferable that the display unit 150 of the image forming apparatus 100t and / or the display unit 230 of the information processing terminal 200t can display the download list. On the other hand, it may not be accessible from the image forming apparatuses 100a to 100c and / or the information processing terminals 200a to 200c.

[0213] In FIG. 18(b), the image forming apparatus 100t forms answer sheets RSa to RSc based on the answer scan data RSDa to RSDc. In this case, the image forming apparatus 100t or the information processing terminal 200t may sort the answer scan data RSDa to RSDc according to the time when the answer scan data RSDa to RSDc was uploaded. Further, it is preferable that the display unit 150 of the image forming apparatus 100t and / or the display unit 230 of the information processing terminal 200t can display the sorted list.

[0214] Alternatively, when the image forming apparatus 100t downloads a plurality of answer scan data included in the answer folder multiple times, the image forming apparatus 100t or the information processing terminal 200t preferably displays the downloaded answer scan data and the non-downloaded answer scan data so that they are visible. For example, it is preferable that the display unit 150 or the display unit 230 displays the answer scan data in different manners according to whether it has been downloaded or not.

[0215] Also, even when the image forming apparatuses 100a to 100c generate the answer scan data RSDa to RSDc by scanning the answer sheets RSa to RSc of different sizes, it is preferable that the image forming apparatus 100t forms the answer sheets RSa to RSc of the same size.

[0216] Also, in FIG. 19(b), the image forming apparatuses 100a to 100c download the evaluation result scan data ESDa to ESDc to form the evaluation result sheets ESa to ESc. In this case, the data management apparatus 300 checks the image forming apparatuses 100a to 100c or the operators A to C that have downloaded the evaluation result scan data ESDa to ESDc, and may create a download list indicating the image forming apparatuses 100a to 100c or the operators A to C that have downloaded the evaluation result scan data ESDa to ESDc.

[0217] Note that the download list is preferably accessible from the image forming apparatus 100t and / or the information processing terminal 200t, and the display unit 150 of the image forming apparatus 100t and / or the display unit 230 of the information processing terminal 200t can display the download list. On the other hand, it may not be accessible from the image forming apparatuses 100a to 100c and / or the information processing terminals 200a to 200c.

[0218] In the above description, the configuration mainly exemplifies the expiration date of the print data as the second display data. However, the present embodiment is not limited to this, and the second display data may be a configuration in which precautions to be taken regarding the handling of the print data are shown.
