  When it is determined that the connection information has been received (S15: YES), the main control unit 11A searches the color management table 101 for colors that can be assigned to the stylus pen 2 having the pen ID included in the connection information. (Step S16). Specifically, the main control unit 11A searches the color management table 101 for a color for which the terminal name and pen ID are not stored. For example, when the color management table 101 is a table as shown in FIG. 4, the main control unit 11A searches for red, green, amber, orange, purple, and the like.

  Thereafter, the main control unit 11A stores the pen ID and the terminal name included in the connection information in the color management table 101 (step S17). For example, the main control unit 11A stores the pen ID and the terminal name in the color management table 101 in association with the color code having the smallest value among the colors of the search result in step S16. The main control unit 11A functions as a storage processing unit of the present invention by executing a control program in step S17. Thereafter, the main control unit 11A transmits the color management table 101 to the client terminal 1B from the communication unit 17A (step S18).

  The main control unit 11B of the client terminal 1B determines whether or not the color management table 101 from the host terminal 1A has been received by the communication unit 17B (step S19). If it is determined that it has not been received (S19: NO), the main control unit 1B waits until the color management table 101 is received.

  When it is determined that the color management table 101 has been received (S19: YES), the main control unit 11B stores the received color management table 101 in the storage unit 12B (step S20), and thereafter ends the processing.

  By the above addition processing, when there is a handwritten input by the newly added stylus pen 2, the client terminal 1 B refers to the color management table 101 stored in step S 20, thereby writing the handwritten locus with the assigned display color. Is displayed. Accordingly, even when a plurality of stylus pens 2 are connected, the client terminal 1B can distinguish the display mode of each stylus pen 2 by receiving the color management table 101 from the host terminal 1A. Therefore, even when a plurality of users input information using the stylus pen 2 to one client terminal 1B, it is possible to distinguish from which user the information is input.

  In the first embodiment, it has been described that the host terminal 1A transmits the color management table 101 in step S18. However, information for identifying the newly added stylus pen 2 and the display color to be assigned to the stylus pen 2 are described. May be transmitted. The main control unit 11B of the client terminal 1B may store the information transmitted from the host terminal 1A in the color management table 101 stored in the storage unit 12B.

  9 and 10 are flowcharts showing the processing procedure of the display system when the change process is performed. The main control unit 11B of the client terminal 1B determines whether or not the change operation described above has been received (step S21). For example, the main control unit 11B determines whether or not position information indicating contact with a specific button or the like displayed on the display panel 3 in order to display the pen setting screen 102 is input from the touch panel control unit 16B. The main control unit 11B functions as request operation accepting means of the present invention by executing a control program in step S21. When it is determined that the change operation has not been received (S21: NO), the main control unit 11B waits until the change operation is received.

  When it is determined that the change operation has been accepted (S21: YES), the main control unit 11B transmits a change request from the communication unit 17B to the host terminal 1A (step S22). The change request includes, for example, the pen ID of the stylus pen 2 used for the received change operation, the terminal name of the client terminal 1B, and information indicating that the change operation has been received.

  The main control unit 11A of the host terminal 1A determines whether or not the change request is received by the communication unit 17A (step S23). When it is determined that the change request has not been received (S23: NO), the main control unit 11A waits until the communication unit 17A receives the change request. When it is determined that the change request has been received (S23: YES), the main control unit 11A transfers the color management table 101 stored in the storage unit 12A from the communication unit 17A to the client terminal 1B that is the transmission source of the change request. Transmit (step S24).

  The main control unit 11B of the client terminal 1B determines whether or not the color management table 101 from the host terminal 1A has been received by the communication unit 17B (step S25). If it is determined that the color management table 101 has not been received (S25: NO), the main control unit 11B waits until the communication unit 17B receives the color management table 101. When it is determined that the color management table 101 has been received (S25: YES), the main control unit 11B displays the pen setting screen 102 on the display panel 3 based on the received color management table 101 (step S26).

  Next, the main control unit 11B determines whether or not an operation for selecting one of the icons 131 to 135 displayed on the pen setting screen 102 has been received (step S27). One icon is an icon in which the mark M is not displayed. The main control unit 11B functions as a selection operation accepting unit of the present invention by executing a control program in step S27. If it is determined that the operation to be selected is not received (S27: NO), the main control unit 11B waits until the operation to be selected is received.

  When it is determined that the operation to be selected is accepted (S27: YES), the main control unit 11B determines whether or not there is a handwriting input by the stylus pen 2 used for the change operation (step S28). When it is determined that there is a handwritten input (S28: YES), the main control unit 11B performs a process of displaying the handwritten locus by the handwritten input on the display panel 3 in the display color represented by the selected icon (step S29). The main control unit 11B functions as display processing means of the present invention by executing a control program in step S29.

  When it is determined that there is no handwritten input (S28: NO), or after the process of step S29, the main control unit 11B transmits color information from the communication unit 17A (step S30). The color information includes, for example, the color code of the display color selected by the selecting operation, the pen ID of the stylus pen 2 used for the selecting operation, and the terminal name of the client terminal 1B.

  The main control unit 11A of the host terminal 1A determines whether or not the color information is received by the communication unit 17A (step S31). If it is determined that the color information is not received (S31: NO), the main control unit 11A waits until the color information is received from the communication unit 17A.

If it is determined that the color information has been received (S31: YES), the main control unit 11A updates the contents of the color management table 101 using the received color information (step S32). Specifically, the main control unit 11 </ b> A refers to the color management table 101 stored in its own storage unit 12 and deletes the pen ID and the terminal name included in the received color information from the color management table 101. Further, the main control unit 11A stores the pen ID and the terminal name included in the color information in the color management table 101 in association with the color code included in the received color information. The main control unit 11A functions as the update processing means of the present invention by executing the control program in step S32. Next, the main control unit 11A transmits the updated color management table 101 to the client terminal 1B from the communication unit 17A (step S33).

  The main control unit 11B of the client terminal 1B determines whether or not the color management table 101 from the host terminal 1A has been received by the communication unit 17B (step S34). If it is determined that the color management table 101 has not been received (S34: NO), the main control unit 11B waits until the color management table 101 is received. When it is determined that the color management table 101 has been received (S34: YES). The main control unit 11B stores the received color management table 101 in the storage unit 12 (step S35). Thereafter, the main control unit 11B finishes the process.

  Through the above change processing, the client terminal 1B can accept an operation of selecting from a display mode other than the display mode already selected when changing the display mode of the handwritten trajectory. Therefore, when information input by a plurality of users is mixed and displayed, it is possible to distinguish from which user the information is input even when the information display mode is changed.

  Further, the client terminal 1B communicates with the host terminal 1A when an operation for requesting a change in display mode is received from the user, and displays a display mode that is not used on the pen setting screen 102, so that The display mode different from the user can be selected by the user.

  Further, when the display mode in the handwritten trajectory input at the client terminal 1B is changed, the host terminal 1A stores the changed display mode in the color management table 101, so that the color management table 101 Updates can be made. Therefore, even when the host terminal 1 </ b> A receives a display mode change request from the third display device 1, for example, the user of the third display device 1 selects a display mode that is not selected. Can do.

When the main control unit 11A of the host terminal 1A receives the change request from the one client terminal 1B in step S23, if the change process related to the other client terminal 1B is being performed, the main control unit 11A performs step S24 until the change process is completed. The processing may not be allowed to proceed.
When a pen ID different from the pen ID included in the color information received in step S31 is stored in the color management table 101 in association with the color code included in the color information, the main control unit 11A performs step S32. Instead of this processing, the color information transmission source may be notified. For example, the main control unit 11A notifies the display panel 3 of the transmission source client terminal 1B to display a message such as “Please select another color” or “Selected by another user”. .
By performing such processing by the main control unit 11A, it is possible to prevent the same display color from being assigned to the stylus pen 2 connected to each of the plurality of client terminals 1B.

  Moreover, the process of step S33-step S35 in FIG. 10 is not essential. For example, if the main control unit 11B of the client terminal 1B determines that the selection operation has been accepted in step S27 in FIG. 9, the contents of the color management table 101 stored in the storage unit 12B in the same process as in step S32 are displayed. You may make it update.

  FIG. 11 is a flowchart illustrating a processing procedure of the display system when performing the release process. The main control unit 11B of the client terminal 1B determines whether to release the connection with the stylus pen 2 via the wireless dongle 20 (step S41). For example, when it is detected that a predetermined operation (such as a depressing operation of a registration release button not shown in the drawing) has been performed with the stylus pen 2, or wireless communication between the wireless dongle 20 and the stylus pen 2 is predetermined. The main control unit 11B determines that the connection with the stylus pen 2 is to be released when the time is interrupted for more than a certain time.

  When it is determined that the connection with the stylus pen 2 is not released (S41: NO), the main control unit 11B waits until the connection is released. When it is determined that the connection of the stylus pen 2 is unlocked (S41: YES), the main control unit 11B updates the pen management table 100 (step S42). Specifically, the main control unit 11B deletes the identifier of the stylus pen 2 to be disconnected from the pen management table 100. Next, the main control unit 11B transmits the release information from the communication unit 17B to the host terminal 1A (step S43). The release information includes the pen ID of the stylus pen 2 that has been disconnected, the terminal name of the client terminal 1B, and information indicating that the stylus pen 2 has been released from the pen connection unit 13B.

  The main control unit 11A of the host terminal 1A determines whether or not the release information is received by the communication unit 17A (step S44). If it is determined that the release information has not been received (S44: NO), the main control unit 11A waits for processing. If it is determined that the release information has been received (S44: YES), the main control unit 11A deletes the pen ID and the terminal name included in the release information from the color management table 101 (step S45). Thereafter, the main control unit 11A transmits the color management table 101 from the communication unit 17A to the client terminal 1B (step S46).

  The main control unit 11B of the client terminal 1B determines whether or not the color management table 101 from the host terminal 1A has been received by the communication unit 17B (step S47). If it is determined that the color management table 101 has not been received (S47: NO), the main control unit 11B waits until the communication unit 17B receives the color management table 101. If it is determined that the color management table 101 has been received (S47: YES), the main control unit 11B stores the received color management table 101 in the storage unit 12B (step S48), and the process is terminated.

  The client terminal 1B can assign the display color assigned to the stylus pen 2 to another stylus pen 2 in order to delete the information of the released stylus pen 2 by the above release processing.

  FIG. 12 is a flowchart illustrating a processing procedure of the display system when the update display process is performed. The main control unit 11B of the client terminal 1B determines whether or not the update timing for updating the display of the annotation screen 103 is reached (step S51). For example, the main control unit 11B determines that the update timing is reached every time a predetermined time such as 1 second elapses from a predetermined time such as when the pen software is activated. When it is determined that the update timing is not reached (S51: NO), the main control unit 11B waits until the update timing is reached.

  When it is determined that the update timing is reached (S51: YES), the main control unit 11B transmits a transmission request for requesting transmission of the color management table 101 stored in the host terminal 1A from the communication unit 17B to the host terminal 1A. (Step S52).

  The main control unit 11A of the host terminal 1A determines whether or not the transmission request is received by the communication unit 17A (step S53). When it is determined that the transmission request is not received (S53: NO), the main control unit 11A waits until the communication unit 17A receives the transmission request.

  If it is determined that a transmission request has been received (S53: YES), the main control unit 11A transmits the color management table 101 stored in the storage unit 12A to the client terminal 1B from the communication unit 17A (step S54).

The main control unit 11B of the client terminal 1B determines whether or not the color management table 101 from the host terminal 1A has been received by the communication unit 17B (step S55). If it is determined that the color management table 101 has not been received (S55: NO), the main control unit 11B waits until the color management table 101 is received. When it is determined that the color management table 101 has been received (S55: YES), the main control unit 11B displays the annotation screen 103 on the display panel 3 based on the received color management table 101 (step S56). For example, the client terminal 1B is configured to store the pen identifier in the pen management table 100 in association with the name for identifying the stylus pen 2 having the pen identifier. In step S56, for example, the main control unit 11B refers to the received color management table 101, extracts the display color information stored in association with the pen ID, and stores the information in association with the identifier corresponding to the pen ID. The name is displayed on the annotation screen 103 together with the name. The main control unit 11B functions as the second display processing means of the present invention by storing the control program in step S56. Thereafter, the main control unit 11B finishes the process.

  By the above update display processing, for example, even when the display mode of the stylus pen 2 is changed a plurality of times, the display mode of the handwritten trajectory input with the stylus pen 2 can be easily distinguished.

  In addition, when the display device 1 according to the first embodiment, that is, the host terminal 1A and the client terminal 1B receives a storage operation for storing the storage content displayed on the display panel 3 from the user, the display device 1 stores the display content. I do. FIG. 13 is a flowchart illustrating a processing procedure of the display device 1 when a storage operation is received. The main control unit 11 of the display device 1 determines whether or not a storage operation has been received from the user (step S61). For example, the main control unit 11 determines whether position information indicating contact with a specific button displayed on the display panel 3 is input from the touch panel control unit 16 in order to store the display content of the display panel 3. The main control unit 11 functions as a storage operation accepting unit by executing a control program in step S61. When it is determined that the storage operation is not accepted (S61: NO), the main control unit 11 waits until the storage operation is accepted. When it is determined that the storage operation has been accepted (S61: YES), the main control unit 11 stores the display content of the display panel 3 in the storage unit 12 (step S62). At this time, the main control unit 11 stores the display content including the handwritten locus input by the stylus pen 2 and the annotation screen 103 in the storage unit 12.

  By storing the display content of the display panel 3 in the storage unit 12 as described above, which stylus pen 2 is used to input the handwritten locus when the user refers to the stored display content of the display panel 3 Can be easily confirmed.

(Embodiment 2)
In the second embodiment, a history of display colors assigned to the stylus pen 2 is displayed on the annotation screen 103. One example will be described below. Since the other configurations and operations other than the configurations and operations described below are the same as those in the first embodiment, the same reference numerals are given to the same parts, and the detailed description of the same configurations and the operations thereof are the same. Description of the effect is omitted.

  FIG. 14 is a schematic diagram illustrating an example of the annotation screen 103 according to the second embodiment. The display device 1 according to the second embodiment displays the current display color of each stylus pen 2 and the previously assigned display color on the display panel 3. In the example of the annotation screen 103 shown in FIG. 14, the display color 103 b assigned to the stylus pen 2 identified by “Host 2” and the display color 103 d previously assigned are displayed. The display color 103d represents black. Therefore, on the display panel 3 on which the annotation screen 103 of FIG. 14 is displayed, handwritten trajectories of the display colors 103b and 103d by the stylus pen 2 identified by “Host 2” are displayed. The display panel 3 displays a handwritten locus of the display color 103a by the stylus pen 2 identified by “Host1” and a handwritten locus of the display color 103c by the stylus pen 2 identified by “Client1”. Has been.

  For example, every time the color management table 101 is updated in step S32 in FIG. 10, the host terminal 1A in the second embodiment distinguishes it from the color management table 101 before update and stores it in the storage unit 12A. For example, when the color management table 101 is stored in the storage unit 12B in step S35 in FIG. 10, the client terminal 1B stores the color management table 101 separately from the previously stored color management table 101. Then, the host terminal 1A and the client terminal 1B each display the annotation screen 103 as shown in FIG. 14 based on the plurality of color management tables 101 stored separately.

  As described above, the display device 1 displays the history of the display color assigned to the stylus pen 2 on the annotation screen 103, so that even if the display color of the stylus pen 2 is changed a plurality of times, It is possible to distinguish whether information is input from the user. In addition, when the display content of the display panel 3 is stored based on the storage operation described in the first embodiment, which user inputs information on the annotation screen 103 when the user refers to the stored display content. Can be easily distinguished.

(Embodiment 3)
In the third embodiment, different line types are assigned to each of the plurality of stylus pens 2 connected to each of the plurality of display devices 1. One example will be described below. Since the other configurations and operations other than the configurations and operations described below are the same as those in the first embodiment, the same reference numerals are given to the same parts, and the detailed description of the same configurations and the operations thereof are the same. Description of the effect is omitted.

  The display device 1 according to the third embodiment includes a line type management table 104 that stores a code for identifying a line type and the pen ID of the stylus pen 2 in association with each other instead of the color management table 101 according to the first embodiment. Such a line type management table 104 is stored in the storage unit 12, for example.

  FIG. 15 is a conceptual diagram showing an example of the line type management table 104. The line type management table 104 includes a line type for displaying handwritten characters and line drawings, a code for identifying the line type, a terminal name connected to the stylus pen 2 to which the line type is assigned, and a pen of the stylus pen 2. The ID is stored in association with each other. In the third embodiment, three of “pen”, “brush pen”, and “marker” are defined as line types, and different codes (1 to 3) are given to the respective line types. Needless to say, the number of line types that can be assigned to each stylus pen 2 may be three or more.

  Here, on the annotation screen 103, a character representing a line type, an image using the corresponding line type, an icon representing the line type, and the like are displayed instead of the display color.

In the display system configured as described above, the host terminal 1A obtains information from the client terminal 1B, thereby performing processing such as addition and deletion of contents stored in the line type management table 104, and sends the information to the client terminal 1B. Processing to transmit the line type management table 104 is performed. The client terminal 1B performs various processes based on the line type management table 104 transmitted from the host terminal 1A. That is, a display system that performs addition processing, change processing, release processing, and update display processing uses the line type management table 104 instead of the color management table 101 of the first embodiment in the processing procedures of FIGS. Specifically, the host terminal 1A and the client terminal 1B each have a color management table 101 according to the first embodiment when a new line type is assigned to the registered stylus pen 2 when the stylus pen 2 is newly added. Instead, various processes are performed using the line type management table 104. Similarly, when the host terminal 1A and the client terminal 1B update the display of the annotation screen 103 when the registered stylus pen 2 is released, the line type management is performed instead of the color management table 101 of the first embodiment. Table 10
Various processes are performed using 4.

  As described above, in the third embodiment, it is possible to assign different line types to each of the plurality of stylus pens 2 connected to each display device 1. Therefore, even when a plurality of users display handwritten trajectories, it is possible to distinguish from which user information is input.

(Embodiment 4)
In the fourth embodiment, different line widths are assigned to the plurality of stylus pens 2 connected to the pen connection unit 13. One example will be described below. Since the other configurations and operations other than the configurations and operations described below are the same as those in the first embodiment, the same reference numerals are given to the same parts, and the detailed description of the same configurations and the operations thereof are the same. Description of the effect is omitted.

  The display device 1 according to the fourth embodiment includes a line width management table 105 that stores a code for identifying the line width and the pen ID of the stylus pen 2 in association with each other, instead of the color management table 101 according to the first embodiment. Such a line width management table 105 is stored in the storage unit 12, for example.

  FIG. 16 is a conceptual diagram showing an example of the line width management table 105. The line width management table 105 stores a line width when displaying a handwritten locus, a code for identifying the line width, and a pen ID of the stylus pen 2 to which the line width is assigned in association with each other. In FIG. 16, a different code (integer value) is given to each line width, but a value obtained by multiplying the line width by an appropriate constant (for example, 10) may be adopted as the code.

  Here, on the annotation screen 103, instead of the display color, a line width value of a character, an image using a line with a corresponding line width, and the like are displayed.

  In the display system configured as described above, the host terminal 1A obtains information from the client terminal 1B, thereby performing processing such as addition and deletion of contents stored in the line width management table 105, and sends the information to the client terminal 1B. Processing for transmitting the line width management table 105 is performed. The client terminal 1B performs various processes based on the line width management table 105 transmitted from the host terminal 1A. That is, the display system that performs the addition process, the change process, the release process, and the update display process uses the line width management table 105 instead of the color management table 101 of the first embodiment in the processing procedure of FIGS. Specifically, the host terminal 1A and the client terminal 1B each have a color management table 101 according to the first embodiment when a new line type is assigned to the registered stylus pen 2 when the stylus pen 2 is newly added. Instead, various processes are performed using the line width management table 105. Similarly, when the host terminal 1A and the client terminal 1B each update the display of the annotation screen 103 when the registered stylus pen 2 is released, the line width management is performed instead of the color management table 101 of the first embodiment. Various processes are performed using the table 105.

  As described above, in the fourth embodiment, it is possible to assign different line widths to the plurality of stylus pens 2 connected to each display device 1. Therefore, even when a plurality of users display handwritten trajectories, it is possible to distinguish from which user information is input.

(Embodiment 5)
