  The terminal device 2 having such a configuration is a personal computer or the like, and by installing predetermined plug-in software, for example, the display device 24 displays the first layer described above and a plurality of layers provided on the upper surface thereof. It is possible to virtually provide it. Further, the display control unit 23 can display appropriate information on these virtually provided layers.

Next, the operation of the information management system configured as described above will be described with reference to the drawings.
In the following description, the user of the terminal device 2 is user A, and the user of the terminal device 3 is user B.
First, when the input device 25 of the terminal device 2 is operated by the user A and the information distribution request for the original information of the identification information α is input to the information management device 1, the information distribution request for the identification information α is 25 to the processing unit 22. The processing unit 22 adds a user ID uniquely assigned to the user A to the information distribution request for the identification information α, and transmits the information to the information management device 1 via the communication device 21 (FIG. 2). Step SA1).
The information distribution request of the identification information α and the user ID of the user A transmitted from the terminal device 2 to the information management device 1 via the network 4 are received by the communication device 14 of the information management device 1 and are sent to the processing unit 13. Is output.

The identification information α and the user ID from the communication device 14 are input to the read permission unit 134 of the processing unit 13. The read permission unit 134 determines whether or not the user ID received from the terminal device 2 is registered in the list held by itself (step SA2 in FIG. 2). As a result, when the user ID is registered in the list (“YES” in step SA2 in FIG. 2), reading of the original information by the reading unit 131 is permitted. As a result, the reading unit 131 reads the original information associated with the identification information α from the first storage device 11 and the comment information associated with the identification information α from the second storage device 12. It is read (step SA3 in FIG. 2). Here, it is assumed that no comment information is written in the original information of the identification information α, and no comment information corresponding to the identification information α exists.
As a result, only the original information is read by the reading unit 131, and this original information is transmitted to the terminal device 2 that is the transmission source of the information distribution request via the communication device 14 (step SA4 in FIG. 2).

  Original information transmitted from the information management device 1 to the terminal device 2 via the network 4 is received by the communication device 21 of the terminal device 2 and output to the processing unit 22. The original information input to the processing unit 22 is output to the display control unit 23. As a result, the original information is displayed on the first layer of the display device 24 by the display control unit 23 (step SA5 in FIG. 2). Here, an example of the original information is shown in FIG. Thus, for example, the original information is configured by combining an image and character information.

  Next, when the input device 25 is operated by the user A on the screen on which the original information as shown in FIG. 3 is displayed, a comment is written on the display screen as shown in FIG. explain.

For example, in the terminal device 2 or 3 in which the plug-in software is installed, a toolbar for writing a comment is displayed on the screen while the original information is displayed. For example, a toolbar capable of performing various operations such as addition of text and lines and insertion of images as shown at the right end of FIGS. 3 and 4 is displayed. By using these various tools by the user, it becomes possible to freely write a comment on the original information displayed on the display screen of the display device 24. Also, the comment can be inserted into a balloon having various shapes such as a circle, a triangle, a quadrangle, and a polygon.
Thus, the comment written by the user is written in a predetermined transparent layer arranged on the upper surface of the first layer included in the display device 24.

  When the input device 25 is operated by the user A, the above-described tool is used, and various comments are written in the transparent layer of the display device 24 (“YES” in step SB1 in FIG. 5). A comment input signal is output from the device 25 to the processing unit 22. Thus, when detecting that a comment has been written in the transparent layer, the processing unit 22 analyzes the written comment and creates comment information (step SB2 in FIG. 5). In other words, the comment information is information necessary for restoring the comment written by the user.

For example, the processing unit 22 specifies a pixel in which each comment is described and specifies attribute information of the comment. For example, as shown in FIG. 6, when the comment is a character, the font type, size, color, type, and the like are specified. If the comment is a graphic, the type of object, the background color of the object, the line color of the object, the definition point of the object, etc. are specified.
In this way, when the processing unit 22 creates the comment information, the information management device 21 transmits the comment information, the identification information α of the original information in which the comment information is written, and the user ID of the user A via the communication device 21. 1 (step SB3 in FIG. 5).

  The comment information, the identification information α, and the user ID transmitted from the terminal device 2 to the information management device 1 via the network 4 are received by the communication device 14 of the information management device 1, and the write permission unit 134 of the processing unit 13. Is output.

  The write permission unit 134 of the processing unit 13 determines whether or not the user ID received from the terminal device 2 is registered in the list held by itself (step SB4 in FIG. 5). As a result, when the user ID is registered in the list (“YES” in step SB4 in FIG. 5), writing of comment information by the writing unit 132 is permitted. As a result, the comment information received from the terminal device 2 is written in the second storage device 12 by the writing unit 132 in association with the identification information α of the original information in which the comment information is written, and thereafter managed. (Step SB5 in FIG. 5).

Next, when the terminal B 3 is operated by the user B and an information distribution request for the identification information α is input, the information distribution request for the identification information α is transmitted together with the user ID of the user B to the terminal apparatus 3. To the information management apparatus 1 via the network 4.
In the information management apparatus that has received the information distribution request for the identification information α, the read permission unit 133 determines whether the user B has the authority to view the comment information, as described above. As a result, if the user has authority, the reading unit 131 reads the original information and the comment information. Here, the second storage device 12 stores the comment information previously written by the user A. Therefore, the reading unit 131 reads the original information and the comment information associated with the identification information α from the first and second storage devices 11 and 12, respectively. The read information is input to the terminal device 3 via the communication device 14 and the network 4.
As a result, the same information as the information displayed on the display device of the terminal device 2 is displayed on the display device of the terminal device 3, that is, the information with the comment superimposed on the original information as shown in FIG. The Rukoto.

Next, a case where a comment is further written by the user B while the screen illustrated in FIG. 4 is displayed on the display device of the terminal device 2 and the terminal device 3 will be described.
In this case, as described above, comment information is created by the processing unit of the terminal device 3, and the comment information, identification information, and user ID are transmitted from the terminal device 3 to the information management device 1.
The information management apparatus 1 that has received this information checks the presence or absence of access authority and stores the comment information in the second storage device 12 as described above.

Here, at present, the terminal device 2 and the terminal device 3 are browsing the same information. As described above, when the same original information is shared by a plurality of terminal devices, the information management device 1 receives from the terminal device 3 the terminal device 2 browsing the same original information. Send comment information.
Thereby, the comment information written by the user B of the terminal device 3 is transmitted to the terminal device 2 via the network 4. This comment information is received by the communication device 21 of the terminal device 2 and output to the processing unit 22. The processing unit 22 outputs this comment information to the display control unit 23. The display control unit 23 displays this comment information on the transparent layer arranged on the upper surface of the first layer on which the original information is displayed.
Thereby, the comment written by the user B is further superimposed on the currently displayed screen, that is, the screen shown in FIG. 4 on the display device 24 of the terminal device 2. It becomes. That is, the comment written by user A and the comment written by user B are displayed superimposed on the original information. At this time, the display control unit 23 displays the original information, the comment written by the user A, and the comment written by the user B on different layers. This makes it possible to distinguish and display each comment. For example, it is possible to easily realize processing such as not displaying only the comment written by the user A.

  In the above-described embodiment, as a method of searching for terminal devices displaying the same original information, for example, for each terminal device that the processing unit 13 of the information management device 1 accesses the information management device 1 It can be realized by holding the history information of the original information transmitted to the terminal device and extracting the terminal device having the same identification information of the original information transmitted most recently in the history information. .

As described above, the information management system according to this embodiment has the following effects.
First, since the original information that was originally created and the comment information that has been modified or added to the original information are managed separately, past history information can be viewed even after correction or addition has been made. There is an effect that can be done.
For example, when only the original information is desired to be browsed, identification information of the original information desired to be browsed may be transmitted to the information management apparatus together with a command indicating that only the original information is desired to be browsed. Thereby, only the original information is read and transmitted by the reading unit 131.

  Secondly, a comment written by one terminal device is transmitted via the information management device 1 to another terminal device displaying the original information in which the comment is written. This makes it possible for all terminal devices sharing the same original information to share comment information written in one terminal device. Thereby, information exchange can be realized in real time.

Third, since the read permission unit 133 permits reading and transmission of comment information only to a terminal device used by a user who is permitted to view comment information, a comment for an unauthorized user is provided. Information transmission is avoided. Thereby, it becomes possible to improve the confidentiality of information.
Fourth, the writing permission unit 134 permits writing to the second storage device 12 only for comment information added by a terminal device used by a user who is permitted to write comment information. It becomes possible to avoid writing of comment information added by an unauthorized user. Thereby, it becomes possible to improve the reliability of information.

As mentioned above, although embodiment of this invention was explained in full detail with reference to drawings, the specific structure is not restricted to this embodiment, The design change etc. of the range which does not deviate from the summary of this invention are included.
First, in the information management device according to the above-described embodiment, the comment information received from the terminal device is stored in the second storage device as being separate from the original information. In this case, the original information stored in the first storage device 11 may be updated.
For example, when an editing command for instructing editing of the original information is input together with the comment information from the terminal device, the writing unit 132 adds the corresponding original information stored in the first storage device 11 with the comment information. Edit and update the new original information. Thereby, when the user desires to update the original information, it becomes possible to respond to the request.

  Second, the writing unit 132 of the information management device 1 classifies the comment information for each user and stores the comment information in the second storage device 12, and the reading unit 131 is the terminal device that is the transmission source of the information distribution request. Only the user's comment information may be read from the second storage device 12 and transmitted to the terminal device. Thereby, since the comment information written by the user of the terminal device is displayed on each terminal device, the information to be provided can be customized. As a result, since the comment written by each user is not viewed by other users, the information management apparatus can be used as a function such as a memo pad or a tag.

Thirdly, the above-described comment information may be displayed in all terminal devices that have received the comment information. In addition, in each terminal device, the comment information is freely selected and only the selected comment information is displayed. It is good also as a structure which is displayed.
Fourth, the access restriction performed by the read permission unit 133 and the write permission unit 134 may be performed according to, for example, the content of the original information, the storage time of the comment information, and the like. It can be set individually and specifically according to the purpose and application.
