[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a telewriting terminal device and, more particularly, to drawing information such as character graphic information at the same time as mutual communication by voice through a communication line such as an ISDN network, a telephone network and a leased line network. The present invention relates to a telewriting terminal device capable of mutually communicating and a plurality of telewriting terminal devices can be interconnected to operate as a conference system.

[0002]

2. Description of the Related Art Conventionally, as a telewriting terminal device, a "telewriting device" described in JP-A-3-150989 has been reported. This is because the telewriting device that does not have the control right sends the correction / correction information for correction / correction to the common screen to the telewriting device that has the control right, and the telewriting device that has the control right has this common screen. The correction / correction information is determined, and the correction / correction information is validated and the common screen is modified / corrected, or invalidated and discarded.

Further, as a conventional telewriting terminal device, a "drawing communication device" described in Japanese Patent Application Laid-Open No. 4-241054 has been reported. This is a system that eliminates the need for exchanging control rights. Once the editing information has been accumulated and if there is a conflict between the delete operation and the editing operation, first the accumulated editing information is read out, and then again. By performing the retouching process, the content inconsistency of the common screen at the time of conflict is prevented.

Further, as a conventional telewriting terminal device, a "telewriting device" described in Japanese Patent Laid-Open No. 3-133244 has been reported. This one is
When multiple telewriting terminal devices are connected in multipoint, the identification information is added to the writing information from each telewriting device to add to the common screen, and only the writing information of the specific telewriting device can be deleted. The display method can be changed.

Further, regarding the conventional telewriting terminal device, the "file management system in the electronic conference system" described in Japanese Patent Application Laid-Open No. 2-230437 has been reported. This is the material used in the conference in the system to prevent discrepancies due to additional corrections when centrally managing the information on the common screen when multiple telewriting devices are connected in multiple points. The information to which the material management information that uniquely identifies is added is delivered from the device of the material distribution source, and when any change is made to the conference material at the device of the material distribution destination, the correction is made from the device of the material distribution destination. The material change information including the information is sent to the material distribution source device, and the material distribution source device centrally manages the material.

Further, as a conventional telewriting terminal device, an "electronic conference system" described in Japanese Patent Laid-Open No. 5-56425 has been reported. This is a system that is an improvement of the "file management method in an electronic conference system" described in Japanese Patent Laid-Open No. 2-230437 mentioned above, and in particular, it is a system that processes the correction processing in real time.

Further, regarding the conventional telewriting terminal device, the "electronic conference system" described in JP-A-61-9073 has been reported. This is an electronic conferencing system that allows all meeting attendees to gather in one place and hold a meeting. A large display is placed for all the meeting attendees to read and write handwritten information. In the conference table, a plurality of display devices are arranged in appropriate places, opinions and ideas are input from each data input device attached to each display device, and a hard copy is printed as necessary.

[0008]

However, in the "telewriting terminal device" described in Japanese Patent Laid-Open No. 3-150989, the telewriting device having the control right is changed from the telewriting device not having the control right. When writing / writing to the common screen of is permitted / denied, the telewriting device having the control right always judges the writing request from the telewriting device which does not have the plural control rights, and the permission / non-permission Since the operation has to be performed, there is a problem that the operation is complicated.

Further, in the "drawing communication device" described in Japanese Patent Laid-Open No. 241054/1992, a multipoint connection is made when the processing for accumulating the retouching information and the retouching processing for the retouching information accumulated are re-executed. There is a problem that the control related to this processing becomes complicated each time one added telewriting device is added, and that page breaks on the common screen and switching of display files are not clearly described. There was a problem.

Further, in the "telewriting device" described in Japanese Patent Laid-Open No. 3-133244, the control at the time of conflict is clearly described such that the adding operation and the deleting operation are simultaneously executed from different terminals. There is a problem such as not
In addition, there is a problem that the control relating to the writing operation and the deleting operation becomes complicated every time one telewriting device connected to the multipoint is added.

Further, in the "file management method in electronic conference system" described in Japanese Patent Laid-Open No. 230304/1990, materials are distributed to each telewriting device, and the materials distributed by each device are independently added. At the end of the meeting, the difference information between the original material and the original material that has been corrected and added is transferred from the material distribution destination to the material distribution source. At this time, the device of the material distribution source manages the original by combining the original and the difference information. As a result, since each handwritten correction is made to the distributed materials, there is a problem that the content including the original materials becomes inconsistent after the conference is over.

Further, in the "electronic conference system" described in Japanese Patent Application Laid-Open No. 5-56425, after the correction operation is performed, the correction information is transmitted to the common display device, and the common display device is operated. Is configured to change the actual display only by replying to. Therefore, there is a problem that the response from the operation of correction and correction to the execution of the display is very poor, and the system has a very poor operability.

Further, in the "electronic conference system" described in Japanese Patent Laid-Open No. 61-9073, only a data input device having a control right for correction / correction is a system in which writing on a common screen is permitted. Therefore, there is a problem that the operation of exchanging the control right becomes very troublesome when the immediate effect is required such as when the discussion is heated.

FIG. 11 shows an image diagram when the conventional telewriting terminal device performs the adding operation and the deleting operation after exchanging the control right. As shown in FIG. 11, in a conventional telewriting terminal device, a plurality of telewriting terminal devices are connected to each other to form an electronic conference system, and between the telewriting terminal devices,
The operation mode is such that the control right (correction / correction right) for permitting the correction / correction on the common screen is exchanged, and only the telewriting terminal device having this control right is allowed to modify / correct the common screen. Since it has been adopted, when the addition occurs in one telewriting terminal device, and the correction occurs at the other telewriting terminal device at the same time,
A mismatch occurred in the contents of the common screen. In addition, there is a problem that confusion regarding the control right occurs when a page break is executed from the other telewriting terminal device while the other telewriting terminal device is editing.

Therefore, according to the present invention, the instruction modes of all the telewriting terminal devices can be unified to the addition / deletion, and by preventing the addition and the deletion from occurring at the same time, a plurality of control rights are not exchanged. It is an object of the present invention to provide a telewriting terminal device capable of inputting telewriting information from the telewriting terminal device.

When the instruction mode change request is received, the own terminal side also determines whether or not the instruction mode change request is in order to determine the conflict with the own terminal side (step S71). If the instruction mode change has occurred competing on the terminal side as well, the instruction mode change response NG is transmitted and the instruction mode change is canceled (step S72).

On the other hand, if no conflict has occurred, it is next determined on the terminal side whether or not drawing input is already being performed in the instruction mode before change (step S73). When the drawing input is not being performed, the instruction mode change response OK is transmitted from the line control unit 1 to the partner terminal (step S74), and the change of the instruction mode is completed, so that the display unit 10 notifies that fact to the operator. Yes (process S75).

On the other hand, when the drawing input is being performed on the terminal side, the input / output control unit 7 cancels the drawing information input from the drawing input unit 8 (process S76). Referring to FIG. 8, in terminal A, instruction mode change response O from terminal B is sent.
When K (OK) is received, the change of the instruction mode has been completed, so the process ends. On the other hand, when the instruction mode change response NG (No) is received from the terminal B in the process S62, the change of the instruction mode has failed, and the fact is displayed on the display unit 10 to notify the operator (process S63).

[0066] Hereinafter, explanation of the present onset bright configurations and operational effects described in the embodiment. When the line control unit 1 receives the instruction mode change request from the partner terminal device and the own terminal device is already performing the telewriting process based on the instruction mode, the input / output control unit 7 forces the telewriting process. Since it is interrupted, it is possible to promptly force the own terminal device to add / delete the instruction mode of the other terminal device.

[0067] (Example 4) can be applied to the tele-writing terminal device described embodiment in Example 1 and similarly Figure 1. In this embodiment,
Specifically described further feature portion of the present onset bright. Figure 10
The page number change and the file number change will be described based on FIG.

FIG. 10 is an image diagram when a file is displayed on the screen of the display unit 10 and a diagram showing the structure of the file. As shown in FIG. 10A, F20 is displayed as a file 1 and a file 2 on the display screen of the display unit 10.
Different files of F21 and F21 are displayed at the same time. The file F20 is composed of pages P1 to P4 as indicated by F22 in FIG. On the other hand, the file F21 is composed of pages P1 to P3 as shown by F23 in FIG. Figure 10
As shown in (a), the first and third pages of F20 and F21 are displayed. In this display state, the file 1 and the file 2 are in a state where the telewriting operation can be input.

The page number change and the file number change will be described with reference to FIG. First, the page number change is a process of switching the currently displayed first page to the third page on the display screen of file 1, for example. The file number change is a process of switching the currently displayed file 1 to another file 3 (not shown) on the display screen of the file 1, for example.

Therefore, if you want to change the page number,
By changing the “instruction mode” in the flowcharts shown in FIGS. 3 to 9 to “page number”, the display page number can be switched. Further, when it is desired to change the file number, the display file number can be switched by replacing the "instruction mode" in the flowcharts shown in FIGS.

[0071] Hereinafter, explanation of the present onset bright configurations and operational effects described in the embodiment. When there are multiple pages of telewriting information, the telewriting process can be performed based on the page number change request instead of the instruction mode change request, and the page numbers displayed on all the telewriting terminal devices are unified, and the page number is displayed. It is possible to simultaneously input telewriting from a plurality of telewriting terminal devices without exchanging the control right by preventing the occurrence of the mismatch. The following is the description of this embodiment.
To illustrate further configuration and effects of the present onset Akira.

When there are multiple files of telewriting information, the telewriting process can be performed based on the file number change request instead of the instruction mode change request, and the file numbers displayed on all the telewriting terminal devices are unified. By preventing occurrence of file number mismatch, it is possible to simultaneously input telewriting from a plurality of telewriting terminal devices without exchanging control rights.

[0073]

According to the present invention, by unifying the instruction modes of all telewriting terminal devices to draw / delete and preventing drawing and deleting from occurring at the same time, a plurality of control rights are not exchanged. It is possible to simultaneously input telewriting from the telewriting terminal device.
