[Operation]
With reference to FIG. 1 to FIG. 5 and FIG. 8 to FIG. 12, the operation of the image display system 50 according to the present embodiment based on the above-described structure and flowchart will be described.

  Referring to FIG. 3, when copy mode is selected, image forming apparatus 100 displays an initial screen of copy basic screen 200 on touch panel display 182 of operation panel 180 (see FIG. 5). When the simultaneous transmission key 232 (see FIG. 4) is operated on the copy basic screen 200 (YES in step S1010 shown in FIG. 9), the image forming apparatus 100 copies the data of the original image read at the time of copy printing. The simultaneous transmission function for transmitting to the electronic blackboard device 300 simultaneously with printing is set to ON (step S1020).

  On the copy basic screen 200, settings such as saddle stitch printing, page aggregation printing, duplex printing, and post-processing such as book binding (saddle stitching) and staple binding are set as copy settings (printing condition settings) during copy printing. Can be set.

  When a document is set on the image forming apparatus 100 and the monochrome start key 246 or the color start key 248 is operated, the image forming apparatus 100 reads image information of the set document and acquires image data of the document. When there are a plurality of documents set on the image forming apparatus 100, the image forming apparatus 100 sequentially reads the plurality of set documents and acquires image data including document image data of each document.

  When the printing conditions are set on the basic copy screen 200, the image forming apparatus 100 executes the printing process of the image data in a manner that reflects the set printing conditions. For example, when double-sided printing and page integration printing are set as printing conditions, the printing process is executed after changing to a layout according to those settings. Further, for example, when staple binding is set as the post-processing setting in the print condition setting, the image forming apparatus 100 executes post-processing for binding the printed paper with staples by the post-processing unit 190.

  1 and 2, when the simultaneous transmission function is set, the image forming apparatus 100 transmits the image data read at the time of copy printing to the electronic blackboard apparatus 300 simultaneously with the copy printing. At this time, if the printing conditions are set on the copy basic screen 200, the display data generation unit 150 displays the display data reflecting the set printing conditions based on the image data read at the time of copy printing. The generated display data is transmitted to the electronic blackboard device 300. When the image data read during copy printing includes a plurality of document image data corresponding to a plurality of documents, display data generated based on the image data also includes a plurality of document image data.

  When the simultaneous transmission function is not set, the image forming apparatus 100 executes normal copy printing processing.

  When the electronic blackboard apparatus 300 receives the data from the image forming apparatus 100, the electronic blackboard apparatus 300 registers the received data in the reception folder. Referring to FIG. 3, electronic blackboard apparatus 300 captures data in the reception folder and touch panel when data capture button 428 is selected (touch operation) by the user (YES in step S2010 shown in FIG. 10). The data is displayed on the display 310 (see FIG. 8), and the data in the reception folder is deleted (step S2020).

  When the received data is display data, an image reflecting the printing conditions set in the image forming apparatus 100 is displayed on the touch panel display 310 of the electronic blackboard device 300. That is, on the touch panel display 310 of the electronic blackboard device 300, an image is displayed in the same manner as a printed material obtained by the copy printing process of the image forming apparatus 100 (a printed material that has been finished based on the set printing conditions). Is done. When the received image data and display data include document image data, the electronic blackboard device 300 displays the document image indicated by the document image data.

  Referring to FIG. 11, when performing copy printing, for example, when a landscape original is double-sided copy-printed and stapled with staples, the touch panel display 310 of the electronic blackboard apparatus 300 is stapled at the upper corner. The image of the sideways original is displayed. Referring to FIG. 12, when copy printing is performed, for example, when a laterally oriented document is set to 2in1 by page aggregation and saddle stitching (book binding) printing is performed, the touch panel display 310 of the electronic blackboard device 300 has a layout of 2in1. An image of the changed saddle stitching (book binding) state is displayed. As described above, the touch panel display 310 of the electronic blackboard device 300 displays an image in the same state as the finished state of the printed matter.

  When the received data is normal image data (when the copy setting is not set), the image forming apparatus 100 does not set the printing condition, so the image data read at the time of copy printing is displayed as it is.

  When the user performs a drawing operation on the screen of the touch panel display 310 on which an image is displayed, the electronic blackboard device 300 displays a drawing image such as characters, figures, and symbols according to the operation.

  Further, when the user performs a page movement operation by a touch gesture operation, the electronic blackboard apparatus 300 switches the display of the document image according to the page order according to the operation. For example, in the case of double-sided copy printing, as shown in FIG. 11, the display image is switched in the order of front → back like a printed matter by a flick touch gesture operation. Further, for example, in the case of saddle stitching (book binding) printing, as shown in FIG. 12, the display image is switched in the book binding order in the same manner as the printed material by a flick touch gesture operation.

  When an operation for taking in (saving) an image is performed after such an editing operation, the electronic blackboard device 300 saves (stores) the image displayed on the touch panel display 310 as image data. When the electronic blackboard apparatus 300 receives a print instruction for the stored image data, the electronic blackboard apparatus 300 transmits the image data to the image forming apparatus 100. When the image forming apparatus 100 receives the image data from the electronic blackboard apparatus 300, the image forming apparatus 100 executes a printing process for the image data.

[Effects of the present embodiment]
As is clear from the above description, the following effects can be obtained by using the image display system 50 according to the present embodiment.

  When the image forming apparatus 100 receives an instruction to start printing by the user, the image forming apparatus 100 executes print processing of the acquired image data in a manner that reflects the set printing conditions, and is set based on the image data. Display data reflecting the printing conditions is generated, and the generated display data is transmitted to the electronic blackboard device 300. The user can simultaneously print the image data and transmit the display data generated based on the image data to the electronic blackboard device 300 according to the instruction to start copy printing once. The image forming apparatus 100 can execute print processing using the acquired image data, generate display data based on the same image data, and transmit the display data to the electronic blackboard apparatus 300. Therefore, printing can be easily performed with a single operation. Processing and data transmission processing to the electronic blackboard device 300 can be executed. Accordingly, it is possible to reduce the time and effort of the operation by the user.

  The image forming apparatus 100 executes image data print processing in a manner that reflects the set print conditions. For this reason, a printed matter that has been subjected to finish processing based on the set printing conditions is obtained. The image forming apparatus 100 further generates display data reflecting the set printing conditions based on the image data to be printed, and transmits the generated display data to the electronic blackboard device 300. The electronic blackboard apparatus 300 receives display data transmitted from the image forming apparatus 100 and displays an image indicated by the received display data. Since the set printing conditions are reflected in the display data, the electronic blackboard device 300 has the same mode as the printed material obtained by the printing process (the printed material subjected to the finishing process based on the set printing conditions). Will display the image. In other words, an image in the same state as the finished state of the printed matter can be displayed on the electronic blackboard device 300. Therefore, for example, when a presentation is performed using the electronic blackboard device 300 at a meeting or the like, an image of the material is displayed on the electronic blackboard device 300 in the same manner as the material distributed in advance (printed material obtained by the printing process). Can be displayed. Accordingly, since the mutual relationship between the image displayed on the electronic blackboard device 300 and the paper material (printed material) distributed at the meeting or the like becomes easy to understand, the distribution material is used when the electronic blackboard device 300 is used for the presentation at the meeting or the like. Smooth confirmation with (printed material) can be facilitated.

  When the electronic blackboard device 300 accepts the touch gesture operation, the electronic blackboard device 300 switches the display of the document image according to the page order. Therefore, for example, when a presentation is performed using the electronic blackboard device 300 in a meeting or the like, the presentation can be performed while displaying an image on the electronic blackboard device 300 in the same manner as the distribution material (printed material). As a result, a more easy-to-understand presentation method can be realized.

  The electronic blackboard device 300 receives a drawing operation by touch and displays a drawing image. Therefore, a character or the like can be drawn on the image indicated by the display data by a drawing operation by the user. Further, an image in which characters or the like are drawn on the image indicated by the display data is stored as image data, and the image data can be transmitted to the image forming apparatus 100 in order to print the image data. When the image forming apparatus 100 receives the image data transmitted from the electronic blackboard apparatus 300, the image forming apparatus 100 executes a printing process for the image data. Therefore, for example, when a presentation is performed using the electronic blackboard device 300 in a meeting or the like, the printed matter of the image displayed on the electronic blackboard device 300 can be distributed to attendees or the like of the meeting as minutes.

However, the programs and the like stored in the image forming apparatus and the electronic blackboard apparatus are different from those in the first embodiment.

  In the present embodiment, when data transmission is performed in step S1090 shown in FIG. 9, the image forming apparatus transmits data relating to copy setting conditions at the time of copy printing to the electronic blackboard apparatus in a pair with document data. When the electronic blackboard apparatus receives the data transmitted from the image forming apparatus, the electronic blackboard apparatus stores data relating to the copy setting conditions in pairs with the original data. When printing from the electronic blackboard apparatus, the electronic blackboard apparatus sets the copy setting condition as a printing condition, for example, in the printer driver of the own machine, based on the data regarding the copy setting condition corresponding to the document data to be printed. As a result, when the image transmitted from the image forming apparatus is printed in the electronic blackboard apparatus, the copy setting condition in the image forming apparatus is set as the default printing condition of the electronic blackboard apparatus.

  In the present embodiment having the above-described configuration, when an original document is scanned and transmitted by an image forming apparatus, for example, when the data after being edited by the electronic blackboard apparatus is reprinted, the original document is not set again. It is possible to obtain printed matter that has the same appearance as the original. Therefore, the operability when printing from the electronic blackboard device is improved.

When the user performs a data capture operation (YES in step S3010), the electronic blackboard apparatus captures the data in the reception folder and displays it in the preview mode on touch panel display 310 (see FIG. 8). Data is deleted (step S3020).

  When the received data is display data, an image reflecting the printing conditions set in the image forming apparatus is previewed on the touch panel display 310 of the electronic blackboard apparatus. That is, the original image is preview-displayed on the touch panel display 310 of the electronic blackboard device in the same manner as a printed matter obtained by copy printing.

  When the electronic blackboard apparatus receives an instruction to switch to the edit mode by the user (YES in step S3030), the electronic blackboard apparatus switches the own mode from the preview mode to the edit mode (step S3040). When a drawing operation is performed on the screen of the touch panel display 310 in the edit mode, the electronic blackboard apparatus displays a drawing image such as characters, figures, symbols, and the like according to the operation (steps S3070 and S3080).

  On the other hand, if the instruction to switch to the edit mode has not been given (NO in step S3030), the electronic blackboard device continues to display the document image in the preview mode without switching to the edit mode. When the user performs a page turning operation by a touch gesture operation in the preview mode (YES in step S3120), the electronic blackboard apparatus switches display of the document image in accordance with the operation (step S3130). That is, a page turning process is executed.

[Effects of the present embodiment]
As is clear from the above description, the following effects can be obtained by using the image display system according to the present embodiment.

  The electronic blackboard apparatus displays the image indicated by the display data in the preview mode immediately after displaying the display data (original data) received from the image forming apparatus on the touch panel display 310. Therefore, as in the first embodiment, an image is displayed on the electronic blackboard device in the same mode (for example, double-sided printing and page aggregation printing) as the printed material (copy recording paper) obtained by the printing process. That is, on the electronic blackboard device, an image of a document that has been subjected to copy printing is displayed in an easy-to-read manner in correspondence with a printed document that has been obtained by copy printing. Therefore, the visibility of the user is improved. On the other hand, when the edit mode is selected, the electronic blackboard apparatus switches to the edit mode and displays an image. In the edit mode, one page is displayed on one screen. Therefore, the editing operation by the user becomes easy and the operability is improved. Thus, the electronic blackboard device according to the present embodiment can achieve both improvement in visibility for the user and improvement in operability.
