The display device 150 displays the hierarchical structure of folders in accordance with a hierarchical structure display signal. Here, regarding folders, a folder A, a folder B, and a folder C are managed in the same level. The operator can select the folder A, the folder B, and the folder C using the operation device 140.

As shown in FIG. 4B, if the operation device 140 receives an operation of the operator selecting a folder, the display device 150 displays a file or a folder inside the selected folder. For example, while the display device 150 displays the hierarchical structure of folders, if the operation device 140 receives an operation of the operator selecting the folder A, the display device 150 displays a file A and a file B included in the selected folder A. The operation device 140 receives an operation of the operator selecting the file A and the file B.

As described above, if the file A and the file B are selected, the communication device 160 transmits a print data designation signal for designating the selected files to the data management apparatus 300.

Here, the first display data indicates printing conditions. The display device 150 displays printing conditions in accordance with the first display data. Printing conditions include the number of printing sheets, the paper size at the time of printing, the kind of paper, necessity of layout change, and printing setting conditions (single-sided printing, double-sided printing).

The return button R is located at the lower right in the display screen 152. The return button R is a button for returning to a previous display screen. If the return button R is operated, the display screen changes to the previous display screen.

A forward button F is located at the lower left in the display screen 152. The forward button F is a button for proceeding to a next display screen. If the forward button F is operated, the display screen changes to the next display screen.

If the forward button F is operated, as shown in FIG. 4D, the display device 150 displays the second display data as a next display screen. The display device 150 displays a deadline related to print data.

The forward button F is located at the lower left in the display screen 152. The forward button F is a button for proceeding to a next display screen. If the forward button F is operated, the display screen changes to the next display screen.

The return button R is located at the lower right in the display screen 152. In this case, the return button R is a button for returning to a previous display screen. If the return button R is operated, the display screen changes to the previous display screen.

In this manner, in the image forming apparatus 100 of the present embodiment, the first display data and the second display data can be displayed in the display screen 152 in a switchable manner by means of an operation of the forward button or the return button. For this reason, even if the display screen 152 of the display device 150 is relatively small, the display device 150 can display a sizable amount of display data.

When the display screen is relatively large, it is preferable that a plurality of pieces of data included in display data be displayed in one display screen.

Accordingly, the assignment scan data SSD is downloaded from the assignment folder of the hierarchical structure of folders of the data management apparatus 300 to the image forming apparatuses 100a to 100c.

The image forming apparatus 100a forms an image corresponding to the assignment scan data SSD on a sheet. Accordingly, the image forming apparatus 100a can form an assignment sheet SSa.

Similarly, the image forming apparatus 100b and the image forming apparatus 100c form images corresponding to the assignment scan data SSD on sheets. Accordingly, the image forming apparatus 100b and the image forming apparatus 100c can form assignment sheets SSb and SSc. Typically, the assignment sheets SSa to SSc of the image forming apparatuses 100a to 100c are the same.

Thereafter, typically, the operator A writes an answer in the assignment sheet SSa. Accordingly, the assignment sheet SSa becomes an answer sheet RSa.

Similarly, the operator B writes an answer in the assignment sheet SSb. Accordingly, the assignment sheet SSb becomes an answer sheet RSb. The operator C writes an answer in the assignment sheet SSc. Accordingly, the assignment sheet SSc becomes an answer sheet RSc.

As shown in FIG. 18A, the image forming apparatus 100a generates answer scan data RSDa obtained by scanning the answer sheet RSa and transmits it to the data management apparatus 300. At this time, the image forming apparatus 100a designates a submission folder of the hierarchical structure in the data management apparatus 300 for storing the answer scan data RSDa and transmits the answer scan data RSDa.

Accordingly, the answer scan data RSDa is uploaded on the submission folder of the hierarchical structure in the data management apparatus 300 from the image forming apparatus 100a.

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 a submission folder of the hierarchical structure in the data management apparatus 300 for storing the answer scan data RSDc and transmits the answer scan data RSDc. Accordingly, the answer scan data RSDc is uploaded on the submission folder of the hierarchical structure in the data management apparatus 300 from the image forming apparatus 100c.

As shown in FIG. 18B, the image forming apparatus 100t forms images on sheets by reading the answer scan data RSDa to the answer scan data RSDc from the submission folder in the data management apparatus 300. Accordingly, the answer scan data RSDa to the answer scan data RSDc are downloaded from the submission folder of the hierarchical structure of folders of the data management apparatus 300 to the image forming apparatus 100t. The image forming apparatus 100t forms images corresponding to the answer scan data RSDa to the answer scan data RSDc on sheets. Accordingly, the image forming apparatus 100t can form the answer sheets RSa to RSc.

Regarding the answer scan data RSDa to the answer scan data RSDc, the image forming apparatus 100t may perform display by extracting only data in which the date and time when each piece of answer scan data is transmitted to the data management apparatus 300 are included in a time zone designated by the operator. In addition, regarding the answer scan data RSDa to the answer scan data RSDc, the image forming apparatus 100t may perform display excluding data which has been marked by the operator T (which will be described below). Even with these, data desired by the operator T can be preferentially displayed, and therefore limitation of display according to display data related to print data can be curbed.

Thereafter, typically, the operator T writes evaluations on the answer sheets RSa to RSc. For example, the operator T marks the answer sheets RSa to RSc. Accordingly, as shown in FIG. 19A, the answer sheets RSa to RSc become evaluation result sheets ESa to ESc.

The image forming apparatus 100t generates evaluation result scan data ESDa to a evaluation result scan data ESDc by scanning the evaluation result sheets ESa to ESc. Thereafter, as shown in FIG. 19A, the image forming apparatus 100t transmits the evaluation result scan data ESDa to the evaluation result scan data ESDc to the data management apparatus 300.

Here, the data management apparatus 300 has a return folder as a folder in addition to the assignment folder and the submission folder. 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.

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

The data management apparatus 300 receives the evaluation result scan data ESDa to the evaluation result scan data ESDc together with folder designation information designating a return folder. The data management apparatus 300 stores the evaluation result scan data ESDa to the evaluation result scan data ESDc in the return folder of the hierarchical structure. Accordingly, the evaluation result scan data ESDa to the evaluation result scan data ESDc are uploaded on the return folder of the hierarchical structure in the data management apparatus 300.

As shown in FIG. 19B, the image forming apparatuses 100a to 100c read and receive the evaluation result scan data ESDa to the evaluation result scan data ESDc from the return folder of the hierarchical structure in the data management apparatus 300. Accordingly, the evaluation result scan data ESDa to the evaluation result scan data ESDc are downloaded to the image forming apparatuses 100a to 100c from the return folder of the hierarchical structure of folders of the data management apparatus 300.
