(20) In the present embodiment, the image forming apparatus is linked with the mobile terminal and screen transition of the image forming apparatus is eliminated so that a user is able to perform various operation input while confirming operation content from the mobile terminal on a screen of the image forming apparatus. For such a configuration, the image forming apparatus 1a is provided with a transmitting portion which, when proximity of the mobile terminal 2 is detected in a state of displaying a specific screen on the operation display portion 14a (corresponding to a display portion of the electronic device of the present invention), transmits operation input information associated with the specific screen in advance to the mobile terminal 2. This transmitting portion corresponds to a transmitting portion of the electronic device of the present invention and is realized by the control portion 15a and the near distance wireless communication portion 19a of the image forming apparatus 1a. More specifically, when the user holds the mobile terminal 2 over the operation display portion 14a of the image forming apparatus 1a, the near distance wireless communication portion 19a of the image forming apparatus 1a detects proximity of the mobile terminal 2, and the near distance wireless communication portion 19a of the image forming apparatus 1a and the near distance wireless communication portion 21 of the mobile terminal 2 have a communication protocol, for example, based on NFC established therebetween to be connected so as to allow communication with each other.

(21) Moreover, examples of the specific screen displayed on the operation display portion 14a of the image forming apparatus 1a include preview screens shown in FIG. 13A through FIG. 13E above. Further, the operation input information transmitted from the image forming apparatus 1a to the mobile terminal 2 is ID information of an operation input item associated with a preview screen in advance or operation input screen information including the ID information of the operation input item associated with the preview screen in advance. As the operation input item, edit items such as double-side setting, page aggregation, punch setting, header setting, blank sheet skip, book printing, footer setting, background pattern setting and staple may be set as they are as shown in FIG. 13A through FIG. 13E, or only the edit item which is frequently used by the user among these edit items may be set selectively. Specifically, for example, only double-side setting, header setting and footer setting are associated with the preview screen in advance. In addition, the ID information of the operation input items is information for discriminating these operation input items and notifying operation content according to the operation input items (such as operation code information). The image forming apparatus 1a is controlled so as to execute the operation content notified with this ID information. Moreover, the operation input screen information in this example is screen data for displaying the above-described operation input items on the screen.

(22) The mobile terminal 2 is provided with a receiving portion which receives, when coming close to the image forming apparatus 1a in a state of having a preview screen displayed on the operation display portion 14a, operation input information associated with a preview screen in advance from the image forming apparatus 1a, a display portion which displays an operation input screen based on the received operation input information, and a transmitting portion which transmits operation content (that is, ID information) instructed by the user from the operation input screen to the image forming apparatus 1a. Note that, this display portion corresponds to a display portion of the mobile terminal of the present invention and is realized by the operation display portion 25 of the mobile terminal 2. Moreover, the receiving portion and the transmitting portion correspond to a receiving portion and a transmitting portion of the mobile terminal of the present invention, and are realized by the control portion 24 and the near distance wireless communication portion 21 of the mobile terminal 2. Here, as a method for displaying the operation input screen on the operation display portion 25 of the mobile terminal 2, two different methods are considered according to content of the operation input information transmitted from the image forming apparatus 1a.

(23) First, as a first method, description will be given for a case where the operation input information is ID information of an operation input item. In this case, the mobile terminal 2 is provided with a storage portion in which operation input screen information associated with the ID information of the operation input item is stored, and the operation display portion 25 displays an operation input screen in accordance with the operation input screen information stored by this storage portion. Note that, this storage portion corresponds to a storage portion of the mobile terminal of the present invention and is realized by the storage portion 22 of the mobile terminal 2. That is, according to the first method, the image forming apparatus 1a transmits the ID information of the operation input item associated with the preview screen in advance to the mobile terminal 2. The operation input screen information is stored in the storage portion 22 of the mobile terminal 2 in association with the ID information of the operation input item, and the operation display portion 25 displays an operation input screen as shown in FIG. 5B described below in accordance with the operation input screen information stored in the storage portion 22.

(24) Further, as a second method, description will be given for a case where operation input information is operation input screen information including ID information of an operation input item. In this case, the operation display portion 25 of the mobile terminal 2 displays an operation input screen in accordance with the operation input screen information received from the image forming apparatus 1a. That is, according to the second method, the operation input screen information including the ID information of the operation input item associated with the preview screen in advance is stored in the storage portion 16a of the image forming apparatus 1a, and this operation input screen information is transmitted to the mobile terminal 2. Then, the operation display portion 25 of the mobile terminal 2 displays the operation input screen in accordance with the operation input screen information from the image forming apparatus 1a. Note that, when a screen resolution of the mobile terminal 2 is not known in the image forming apparatus 1a side, the image forming apparatus 1a may obtain the screen resolution of the mobile terminal 2 when being connected to the mobile terminal 2 through near distance wireless communication so as to be able to convert the operation input screen information as appropriate according to this screen resolution.

(25) Furthermore, the image forming apparatus 1a is provided with a receiving portion which receives the operation content (ID information) instructed by the user from the mobile terminal 2 and an updating portion which updates the preview screen in accordance with the received operation content. Note that, this receiving portion corresponds to a receiving portion of the electronic device of the present invention and is realized by the control portion 15a and the near distance wireless communication portion 19a of the image forming apparatus 1a. Moreover, the updating portion corresponds to an updating portion of the electronic device of the present invention and is realized as one function of the control portion 15a of the image forming apparatus 1a. Description will be given below for a specific example of the operation input method according to the operation input system above based on FIG. 3A and FIG. 3B to FIG. 6.

(26) FIG. 3A and FIG. 3B are flowcharts explaining exemplary processing of the image forming apparatus 1a shown in FIG. 2. FIG. 4 is a flowchart explaining exemplary processing of the mobile terminal 2 shown in FIG. 2. In FIG. 3A, first, the image forming apparatus 1a displays a preview screen 141a shown in FIG. 5A on the operation display portion 14a according to predetermined operation input by the user (step S1). In an example of FIG. 5A, “Page 1”, “Page 2”, “Page 3”, . . . are displayed as print preview images. Then, when the mobile terminal 2 comes close to the image forming apparatus 1a in a state where the preview screen 141a is displayed, the image forming apparatus 1a judges whether or not connection of near distance wireless communication with the mobile terminal 2 is established (step S2).

(27) Next, when judging that connection of near distance wireless communication with the mobile terminal 2 is established at step S2 above (in the case of YES), the image forming apparatus 1a judges whether or not there is a transmission request of operation input information from the mobile terminal 2 (step S3). On the other hand, when it is judged that connection of near distance wireless communication with the mobile terminal 2 is not established at step S2 above (in the case of NO), the procedure shifts to a standby state at step S2. When judging that there is a transmission request of the operation input information from the mobile terminal 2 at step S3 above (in the case of YES), the image forming apparatus 1a then transmits the operation input information associated with the preview screen 141a in advance to the mobile terminal 2 (step S4), and further transmits a possible and impossible combination table of the operation input information shown in FIG. 6 to the mobile terminal 2 (step S5). In this example, ID information of the edit items which are set in advance by the user, here, double-side setting, header setting and footer setting concerning editing of a print preview image is transmitted as the operation input information. On the other hand, when it is judged that there is no transmission request of the operation input information from the mobile terminal 2 at step S3 above (in the case of NO), the procedure shifts to a standby state at step S3.

(28) In the mobile terminal 2, operation input screen information associated with the ID Information of double-side setting, header setting and footer setting, which is transmitted from the image forming apparatus 1a, is stored, and an operation input screen is displayed on the operation display portion 25 in accordance with this operation input screen information. A screen of various edit menus which is one example of this operation input screen is shown in FIG. 5B. That is, edit items composed of double-side setting, header setting and footer setting are displayed so as to be selectable by the user on the screen of various edit menus 251 of FIG. 5B.

(29) Here, the possible and impossible combination table of FIG. 6 will be explained. This possible and impossible combination table is for judging whether or not combination is allowed among a plurality of edit items displayed on the screen of various edit menus 251 of FIG. 5B. An example of FIG. 6 is a table configuration when the edit items included in a screen of various edit menus 102 shown in FIG. 13A through FIG. 13E above are targeted, in which items which are allowed to be combined are set as “1” and items which are not allowed to be combined are set as “0” for each edit item of page aggregation, book printing, blank sheet skip, background pattern setting, . . . . For example, in the case of page aggregation, book printing is not allowed to be combined, and blank sheet skip and background pattern setting are allowed to be combined. That is, when it is assumed that page aggregation, book printing, blank sheet skip and background pattern setting are displayed on the screen of various edit menus 251 of FIG. 5B, if the user selects page aggregation, combination with book printing is not allowed to be selected, and combination with blank sheet skip and background pattern setting are allowed to be selected.

(30) Then, in a processing flow of FIG. 3B, the image forming apparatus 1a judges whether or not separation of the mobile terminal 2 is detected (step S6), and when separation of the mobile terminal 2 is detected, that is, it is judged that the mobile terminal 2 is outside a range of near distance wireless communication (in the case of YES), near distance wireless communication is interrupted once, so that while the preview screen 141a is being displayed, whether or not the mobile terminal 2 is held over the preview screen 141a again and connection of near distance wireless communication with the mobile terminal 2 is established is judged (step S7). On the other hand, at step S6, when separation of the mobile terminal 2 is not detected, that is, it is judged that the mobile terminal 2 is within the range of near distance wireless communication (in the case of NO), the procedure shifts to step S8 while the preview screen 141a is being displayed. When judging that connection of near distance wireless communication with the mobile terminal 2 is established at step S7 above (in the case of YES), the image forming apparatus 1a then judges whether or not there is a reflecting request of operation content from the mobile terminal 2 (step S8). On the other hand, when it is judged that connection of near distance wireless communication with the mobile terminal 2 is not established at step S7 above (in the case of No), the procedure shifts to a standby state at step S7.

(31) When judging that there is a reflecting request of operation content from the mobile terminal 2 at step S8 above (in the case of YES), the image forming apparatus 1a then receives operation content selected and set by the mobile terminal 2 from the mobile terminal 2 (step S9). In the example of FIG. 5B, footer setting is selected and set by the user, and “footer/date” is received as the operation content. On the other hand, when it is judged that there is no reflecting request of operation content from the mobile terminal 2 at step S8 above (in the case of NO), the procedure shifts to a standby state at step S8.

(32) The image forming apparatus 1a then updates the preview screen 141a of the operation display portion 14a shown in FIG. 5A based on the operation content received at step S9, that is, “footer/date” designated on the screen of various edit menus 251 of FIG. 5B (step S10). Specifically, the user selects one to be edited by a touch operation from among the print preview images “Page 1”, “Page 2”, “Page 3”, . . . displayed on the preview screen 141a. For example, as shown in FIG. 5C, when “Page 1” is selected by the user, a date is automatically inserted in a footer 142a of this “Page 1”. Note that, if there is a page which is desired to be edited other than “Page 1”, when the user touches the corresponding page on the preview screen 141a, the same content is reflected immediately.

(33) Then, the image forming apparatus 1a judges whether or not other operation content is received from the mobile terminal 2 (step S11), and if judging that other operation content is received (in the case of YES), repeats processing after returning to step S10, and if not (in the case of NO), the procedure ends as it is. In this manner, when there are a plurality of operation content selected and set by the mobile terminal 2, each time operation content is received from the mobile terminal 2, the preview screen 141a is updated.

(34) Next, a processing flow of the mobile terminal 2 will be explained based on FIG. 4. First, as shown in FIG. 5A, in a state where the preview screen 141a is displayed on the operation display portion 14a of the image forming apparatus 1a, the mobile terminal 2 is held over the preview screen 141a. At this time, the mobile terminal 2 judges whether or not connection of near distance wireless communication with the image forming apparatus 1a is established (step S21).

(35) When judging that connection of near distance wireless communication with the image forming apparatus 1a is established at step S21 above (in the case of YES), the mobile terminal 2 requests the image forming apparatus 1a to transmit operation input information (step S22). The mobile terminal 2 then receives the operation input information associated with the preview screen 141a in advance from the image forming apparatus 1a (step S23), and further receives a possible and impossible combination table of the operation input information shown in FIG. 6 from the image forming apparatus 1a (step S24). In this example, in the same manner as the processing flow of FIG. 3A and FIG. 3B, ID information of the edit items which are set in advance by the user, here, double-side setting, header setting and footer setting concerning editing of a print preview image is received as the operation input information. On the other hand, when it is judged that connection of near distance wireless communication with the image forming apparatus 1a is not established at step S21 above (in the case of NO), the procedure shifts to a standby state at step S21.

(36) When receiving the ID information of double-side setting, header setting and footer setting from the image forming apparatus 1a, the mobile terminal 2 displays an operation input screen on the operation display portion 25 in accordance with operation input screen information stored in the storage portion 22 (step S25). The screen of various edit menus 251 which is one example of this operation input screen is as shown in FIG. 5B. That is, operation input items (edit items) composed of double-side setting, header setting and footer setting are displayed so as to be selectable by the user on the screen of various edit menus 251 of FIG. 5B.

(37) The mobile terminal 2 judges whether or not the operation input item is selected by the user from the screen of various edit menus 251 displayed on the operation display portion 25 (step S26), and when judging that the operation input item is selected (in the case of YES), judges whether or not there is an item which is not able to be combined with the selected operation input item by referring to the possible and impossible combination table of FIG. 6 (step S27). On the other hand, when it is judged that the operation input item is not selected at step S26 (in the case of NO), the procedure shifts to a standby state at step S26.

(38) When judging that there is an item which is not able to be combined with the operation input item selected above at step S27 (in the case of YES), the mobile terminal 2 turns the item which is not able to be combined into a selection disabled state, for example, such as gray out display or non-display on the screen of various edit menus 251 (step S28). On the other hand, when it is judged that there is no item which is not able to be combined with the selected operation input item at step S27 (in the case of NO), the procedure shifts to step S29.

(39) The mobile terminal 2 judges whether or not there is selection of other operation input item by the user (step S29), and when judging that there is selection of other operation input item (in the case of YES), repeats processing after returning to step S27. On the other hand, when it is judged that there is no selection of other operation input item at step S29 (in the case of NO), the image forming apparatus 1a is requested to reflect the operation content selected and set in the screen of various edit menus 251 of FIG. 5B and the operation content is transmitted to the image forming apparatus 1a (step S30). Note that, after the mobile terminal 2 receives the operation input information and the possible and impossible combination table from the image forming apparatus 1a at step S23 and step S24, the mobile terminal 2 may be separated from the image forming apparatus 1a. That is, the screen of various edit menus 251 of the mobile terminal 2 may be operated in a state where the user separates the mobile terminal 2 from the image forming apparatus 1a. In this case, when the mobile terminal 2 is caused to come close to the preview screen 141a of the image forming apparatus 1a again, the mobile terminal 2 and the image forming apparatus 1a are connected through near distance wireless communication. The image forming apparatus 1a is then requested to reflect the operation content from the mobile terminal 2 and the above-described operation content is transmitted to the image forming apparatus 1a.

(40) In this manner, according to the present embodiment, the image forming apparatus is linked with the mobile terminal and screen transition of the image forming apparatus is eliminated, so that various operation input is able to be performed while confirming operation content from the mobile terminal on a screen of the image forming apparatus.

Second Embodiment

(41) Though near distance wireless communication such as NFC is used for wireless communication of the image forming apparatus 1a and the mobile terminal 2 in the first embodiment described above, other wireless communication capable of longer-distance wireless communication than this near distance wireless communication may be used. For example, WiFi which is a kind of wireless LAN, Bluetooth (registered trademark, same applies below) suitable for wireless communication of about several meters, and the like are applicable. In the exemplary configuration of FIG. 2, the image forming apparatus 1a and the mobile terminal 2 are respectively provided with the wireless LAN-I/F 18a and the wireless LAN-I/F 23 and capable of wireless communication by wireless LAN (WiFi).

(42) FIG. 7 is a flowchart explaining exemplary processing of the image forming apparatus 1a according to a second embodiment of the present invention. FIG. 8 is a diagram showing one example of a WiFi pairing setting screen displayed on the image forming apparatus 1a. First, the user displays the WiFi pairing setting screen of FIG. 8 on the operation display portion 14a of the image forming apparatus 1a in advance, and sets whether to make WiFi pairing valid or invalid when connection of near distance wireless communication between the image forming apparatus 1a and the mobile terminal 2 is established. In this example, WiFi pairing is set to be valid.

(43) In FIG. 7, the image forming apparatus 1a displays the preview screen 141a shown in FIG. 5A on the operation display portion 14a according to predetermined operation input by the user (step S31). In the example of FIG. 5A, “Page 1”, “Page 2”, “Page 3”, . . . are displayed as print preview images. Then, when the mobile terminal 2 is caused to come close to the preview screen 141a in a state where the preview screen 141a is displayed, the image forming apparatus 1a judges whether or not connection of near distance wireless communication with the mobile terminal 2 is established (step S32).

(44) When judging that connection of near distance wireless communication with the mobile terminal 2 is established at step S32 above (in the case of YES), the image forming apparatus 1a refers to the WiFi pairing setting of FIG. 8, and because it is set to be “valid” here, executes wireless LAN pairing (step S33). On the other hand, when it is judged that connection of near distance wireless communication with the mobile terminal 2 is not established at step S32 above (in the case of NO), the procedure shifts to a standby state at step S32.

(45) The image forming apparatus 1a judges whether or not connection of wireless LAN with the mobile terminal 2 is established (step S34). When it is judged that connection of wireless LAN with the mobile terminal 2 is established (in the case of YES), the near distance wireless communication with the mobile terminal 2 is finished (step S35). On the other hand, when it is judged that connection of wireless LAN with the mobile terminal 2 is not established at step S34 (in the case of NO), the procedure shifts to a standby state at step S34.

(46) The image forming apparatus 1a judges whether or not there is a transmission request of operation input information from the mobile terminal 2 through wireless LAN (step S36), and when judging that there is a transmission request of operation input information from the mobile terminal 2 (in the case of YES), transmits the operation input information associated with the preview screen 141a in advance to the mobile terminal 2 (step S37), and further transmits the possible and impossible combination table of the operation input information shown in FIG. 6 to the mobile terminal 2 (step S38). In this example, ID information of the edit items which are set in advance by the user, here, double-side setting, header setting and footer setting concerning editing of a print preview image is transmitted as the operation input information. On the other hand, when it is judged that there is no transmission request of the operation input information from the mobile terminal 2 at step S36 above (in the case of NO), the procedure shifts to a standby state at step S36.

(47) Though the same content explained in the first embodiment described above is applied for the mobile terminal 2, when ID information of double-side setting, header setting and footer setting and the possible and impossible combination table (FIG. 6) are received from the image forming apparatus 1a through wireless LAN, an operation input screen is displayed on the operation display portion 25 in accordance with operation input screen information stored in the storage portion 22. The screen of various edit menus 251 which is one example of this operation input screen is as shown in FIG. 5B. That is, edit items composed of double-side setting, header setting and footer setting are displayed so as to be selectable by the user on the screen of various edit menus 251 of FIG. 5B. Further, since it is also the same as to the possible and impossible combination table of FIG. 6, the description is omitted here.

(48) The image forming apparatus 1a judges whether or not there is a reflecting request of operation content from the mobile terminal 2 through wireless LAN (step S39), and when judging that there is a reflecting request of operation content from the mobile terminal 2 (in the case of YES), receives the operation content selected and set by the mobile terminal 2 from the mobile terminal 2 (step S40). In the example of FIG. 5B, footer setting is selected and set by the user, and “footer/date” is received as the operation content. The image forming apparatus 1a then updates the preview screen 141a of the operation display portion 14a shown in FIG. 5A as shown in FIG. 5C based on the operation content received at step S40, that is, “footer/date” designated on the screen of various edit menus 251 of FIG. 5B (step S41). On the other hand, when it is judged that there is no reflecting request of operation content from the mobile terminal 2 at step S39 above (in the case of NO), the procedure shifts to a standby state at step S39.

(49) Then, the image forming apparatus 1a judges whether or not other operation content is received from the mobile terminal 2 (step S42), and if judging that other operation content is received (in the case of YES), repeats processing after returning to step S41, and if not (in the case of NO), the procedure ends as it is. In this manner, when there are a plurality of operation content selected and set by the mobile terminal 2, each time operation content is received from the mobile terminal 2, the preview screen 141a is updated.

(50) In this manner, according to the present embodiment, in addition to the effect by the first embodiment, since the image forming apparatus and the mobile terminal are connected through wireless LAN, it is not necessary to hold over the mobile terminal for each operation input and it is possible to perform operation input even from a place relatively away from the image forming apparatus.

(55) In the present embodiment, the electronic blackboard is linked with the mobile terminal and screen transition of the electronic blackboard is eliminated so that a user is able to perform various operation input while confirming operation content from the mobile terminal on a screen of the electronic blackboard. For such a configuration, the electronic blackboard 1b is provided with a transmitting portion which, when proximity of the mobile terminal 2 is detected in a state of having a specific screen displayed on the operation display portion 13b (corresponding to a display portion of the electronic device of the present invention), transmits operation input information associated with the specific screen in advance to the mobile terminal 2. This transmitting portion corresponds to a transmitting portion of the electronic device of the present invention and is realized by the control portion 14b and the near distance wireless communication portion 12b of the electronic blackboard 1b. More specifically, when the user holds the mobile terminal 2 over the operation display portion 13b of the electronic blackboard 1b, the near distance wireless communication portion 12b of the electronic blackboard 1b detects proximity of the mobile terminal 2, and the near distance wireless communication portion 12b of the electronic blackboard 1b and the near distance wireless communication portion 21 of the mobile terminal 2 have a communication protocol based on, for example, NFC established therebetween to be connected so as to allow communication with each other.

(56) Moreover, examples of the specific screen displayed on the operation display portion 13b of the electronic blackboard 1b include handwriting input screens shown in FIG. 14A through FIG. 14D above. Further, the operation input information transmitted from the electronic blackboard 1b to the mobile terminal 2 is ID information of an operation input item associated with a handwriting input screen in advance or operation input screen information including the ID information of the operation input item associated with the handwriting input screen in advance. As the operation input item, edit items such as a type, a size and a color of a stylus may be set as they are as shown in FIG. 14A through FIG. 14D, or only the edit item which is frequently used by the user among these edit items may be set selectively. Specifically, for example, only a stylus color is associated with the handwriting input screen in advance. In addition, the ID information of the operation input items is information for discriminating these operation input items and notifying operation content according to the operation input items. The electronic blackboard 1b is controlled so as to execute the operation content notified with this ID information. Moreover, the operation input screen information is information of a size, arrangement and the like for displaying the above-described operation input items on a screen as icons.

(57) The mobile terminal 2 is provided with a receiving portion which, when coming close to the electronic blackboard 1b in a state of having a screen displayed on the operation display portion 13b, receives operation input information associated with the handwriting input screen in advance from the electronic blackboard 1b, a display portion which displays an operation input screen based on the received operation input information, and a transmitting portion which transmits operation content (that is, ID information) instructed by the user from the operation input screen to the electronic blackboard 1b. Note that, this display portion corresponds to a display portion of the mobile terminal of the present invention and is realized by the operation display portion 25 of the mobile terminal 2. Moreover, the receiving portion and the transmitting portion correspond to a receiving portion and a transmitting portion of the mobile terminal of the present invention, and are realized by the control portion 24 and the near distance wireless communication portion 21 of the mobile terminal 2. Here, as a method for displaying the operation input screen on the operation display portion 25 of the mobile terminal 2, in the same manner as the case of the first embodiment, two different methods are considered according to content of the operation input information transmitted from the electronic blackboard 1b, but repetitive description is omitted here.

(58) Furthermore, the electronic blackboard 1b is provided with a receiving portion which receives the operation content (ID information) instructed by the user from the mobile terminal 2 and an updating portion which updates the handwriting input screen in accordance with the received operation content. Note that, this receiving portion corresponds to a receiving portion of the electronic device of the present invention and is realized by the control portion 14b and the near distance wireless communication portion 12b of the electronic blackboard 1b. Moreover, the updating portion corresponds to an updating portion of the electronic device of the present invention and is realized as one function of the control portion 14b of the electronic blackboard 1b. Note that, also in the present embodiment, wireless communication such as wireless LAN (WiFi) or Bluetooth may be used instead of near distance wireless communication. Though a basic processing flow of an operation input method when the electronic blackboard 1b is applied is the same as the case of the image forming apparatus 1a, description will be given for some specific examples based on FIG. 10A through FIG. 10C to FIG. 12A through FIG. 12D.

(59) FIG. 10A through FIG. 10C are diagrams explaining exemplary processing of the operation input system according to the third embodiment of the present invention. First, the electronic blackboard 1b displays a handwriting input screen 131b as shown in FIG. 10A, that is, the handwriting input screen 131b including a handwriting input image 132b on the operation display portion 13b according to predetermined operation input by the user. When detecting proximity of the mobile terminal 2 in a state where the handwriting input image 132b is displayed on the handwriting input screen 131b, the electronic blackboard 1b then transmits operation input information associated with the handwriting input screen 131b in advance to the mobile terminal 2. In this example, ID information of the edit item which is set in advance by the user, here, a stylus color concerning editing of a handwriting input image is transmitted as the operation input information.

(60) In the mobile terminal 2, operation input screen information associated with the ID Information of the stylus color, which is transmitted from the electronic blackboard 1b, is stored, and the operation input screen is displayed on the operation display portion 25 in accordance with this operation input screen information. A stylus color edit screen which is one example of this operation input screen is shown in FIG. 10B. That is, black, red and green are displayed as the stylus color so as to be selectable by the user on the stylus color edit screen 252 of FIG. 10B. The mobile terminal 2 transmits operation content selected and set by the user for this stylus color edit screen 252 to the electronic blackboard 1b.

(61) The electronic blackboard 1b receives the operation content selected and set by the mobile terminal 2 from the mobile terminal 2. In the example of FIG. 10B, the stylus color “red” is selected and set by the user, and “stylus color/red” is received as this operation content. The electronic blackboard 1b then updates the handwriting input screen 131b of the operation display portion 13b shown in FIG. 10A based on the operation content received from the mobile terminal 2, that is, “stylus color/red” designated on the stylus color edit screen 252 of FIG. 10B. Specifically, for example, as shown in FIG. 10C, a stylus color of the handwriting input image 133b which is input by handwriting to the handwriting input screen 131b is changed to “red”. Note that, a stylus color of the handwriting input image 132b which has been already displayed may be also changed with the same content.

(62) FIG. 11A through FIG. 11C are diagrams explaining another exemplary processing of the operation input system according to the third embodiment of the present invention. First, the electronic blackboard 1b displays the handwriting input screen 131b as shown in FIG. 11A, that is, the handwriting input screen 131b including a transmission destination address input field 134b on the operation display portion 13b according to predetermined operation input by the user. Note that, handwriting input is made invalid in a state where the transmission destination address input field 134b is displayed. When detecting proximity of the mobile terminal 2 in a state where the transmission destination address input field 134b is displayed on the handwriting input screen 131b, the electronic blackboard 1b then transmits operation input information associated with the handwriting input screen 131b in advance to the mobile terminal 2. In this example, ID information corresponding to the transmission destination address input field 134b is transmitted as the operation input information.

(63) In the mobile terminal 2, operation input screen information associated with the ID Information of the transmission destination address input field, which is transmitted from the electronic blackboard 1b, is stored, and the operation input screen is displayed on the operation display portion 25 in accordance with this operation input screen information. A transmission destination address input screen which is one example of this operation input screen is shown in FIG. 11B. That is, the transmission destination address input screen 253 of FIG. 11B includes a transmission destination address input field 253a and a virtual keyboard 253b. Note that, the virtual keyboard 253b is originally mounted on the mobile terminal 2 and is displayed in cooperation with display of the transmission destination address input field 253a. The user inputs desired address information (here, abc . . . ) by a touch operation for this virtual keyboard 253b. The content of this operation input is reflected and displayed in the transmission destination address input field 253a. For example, when a predetermined transmission button (not shown) is pressed by the user, the mobile terminal 2 then transmits operation content input from the transmission destination address input screen 253 to the electronic blackboard 1b.

(64) The electronic blackboard 1b receives the operation content input by the mobile terminal 2 from the mobile terminal 2. In the example of FIG. 11B, “abc . . . ” is input by the user as a transmission destination address, and “abc . . . ” is received as this operation content. Then, the electronic blackboard 1b updates the handwriting input screen 131b of the operation display portion 13b shown in FIG. 11A based on the operation content received from the mobile terminal 2, that is, “abc . . . ” designated on the transmission destination address input screen 253 of FIG. 11B. Specifically, for example, as shown in FIG. 11C, the operation content “abc . . . ” is automatically reflected in the transmission destination address input field 134b of the handwriting input screen 131b.

(65) FIG. 12A through FIG. 12D are diagrams explaining still another exemplary processing of the operation input system according to the third embodiment of the present invention. First, the electronic blackboard 1b displays the handwriting input screen 131b as shown in FIG. 12A, that is, the handwriting input screen 131b including the handwriting input image 132b on the operation display portion 13b according to predetermined operation input by the user. When detecting proximity of the mobile terminal 2 in a state where the handwriting input image 132b is displayed on the handwriting input screen 131b, the electronic blackboard 1b then transmits operation input information associated with the handwriting input screen 131b in advance to the mobile terminal 2. In this example, a page list including the handwriting input image 132b, that is, a page list including handwriting input images P1 to P4 with the handwriting input image 132b as P1 is transmitted as the operation input information.

(66) In the mobile terminal 2, operation input screen information associated with the page list transmitted from the electronic blackboard 1b is stored, and the operation input screen is displayed on the operation display portion 25 in accordance with this operation input screen information. A page list screen which is one example of this operation input screen is shown in FIG. 12B. That is, the handwriting input images P1 to P4 are displayed so as to be selectable by the user on the page list screen 254 of FIG. 12B. The mobile terminal 2 transmits operation content selected by the user for this page list screen 254 to the electronic blackboard 1b. Here, “P4” corresponding to the handwriting input image P4 is transmitted as shown in FIG. 12C.

(67) The electronic blackboard 1b receives the operation content selected by the mobile terminal 2 from the mobile terminal 2. In the example of FIG. 12C, the handwriting input image P4 is selected by the user and “P4” is received as this operation content. Then, the electronic blackboard 1b updates the handwriting input screen 131b of the operation display portion 13b shown in FIG. 12A based on the operation content received from the mobile terminal 2, that is, “P4” designated on the page list screen 254 of FIG. 12C. Specifically, for example, as shown in FIG. 12D, the handwriting input image 132b (P1) displayed on the handwriting input screen 131b is switched to the handwriting input image 135b (P4).

(68) In this manner, according to the present embodiment, the electronic blackboard is linked with the mobile terminal and screen transition of the electronic blackboard is eliminated so that various operation input is able to be performed while confirming operation content from the mobile terminal on a screen of the electronic blackboard.

(69) As above, though description has been given by exemplifying the operation input system, the electronic device, the mobile terminal and the operation input method as each embodiment of the present invention, the present invention may have a form as a program for causing a computer to execute this operation input method or a form as a computer readable recording medium having this program recorded therein.

(70) As the above-described recording medium, specifically, a CD-ROM (-R/-RW), a magneto-optical disk, an HD (hard disk), a DVD-ROM (-R/-RW-RAM), an FD (flexible disk), a flash memory, a memory card, a memory stick, other various ROMs and RAMs and the like are able to be assumed, and realizing of this method is facilitated by recoding the program for causing the computer to execute the operation input method of the present invention described above in these recording mediums for distribution. In addition, the operation input method according to the present invention is able to be executed by mounting the recording medium as described above in an information processing apparatus such as a computer to read the program by the information processing apparatus or by storing this program in the recording medium provided in the information processing apparatus to read as necessary.

(71) Further, according to the present invention, the electronic device such as the image forming apparatus is linked with the mobile terminal and screen transition of the electronic device is eliminated so that various operation input is able to be performed while confirming operation content from the mobile terminal on a screen of the electronic device.
