This electronic blackboard has a large touch panel type display, and displays a drawn image drawn by each user with a dedicated electronic pen or a finger. Unlike conventional whiteboards, it is possible to save drawn images as electronic data and display images from a PC (Personal Computer). Each user can now proceed with meetings and classes while looking at the same screen on the electronic blackboard.

By the way, an authentication method using an IC card for personal authentication has become widespread, and a user may be able to log in to various electronic devices such as an electronic blackboard without entering a user ID and password. Since an individual is identified if the individual is successfully authenticated, a service using an individual identification function using an IC card has also been devised (see, for example, Patent Document 1). Patent Document 1 displays a plurality of e-mail addresses associated with an individual specified by an IC card, and transmits a scanned image of a manuscript to the e-mail address selected by pressing a button by the user. The device is disclosed.

However, the conventional technique has a problem that the operability is not always good because the e-mail address cannot be selected unless the user presses a button.

In view of the above problems, it is an object of the present invention to provide an electronic blackboard with improved operability when selecting an e-mail address.

In view of the above problems, the present invention is an electronic blackboard capable of communicating with an information processing device that manages a plurality of e-mail addresses via a network, and is a terminal identification information acquisition means for acquiring terminal identification information from the terminal device. A transmission request for an e-mail address including the terminal identification information is transmitted to the information processing apparatus, and as a response to the transmission request for the e-mail address, the plurality of e-mail addresses associated with the terminal identification information are used. When the terminal identification information acquisition means acquires the terminal identification information after acquiring the plurality of e-mail addresses by the e-mail address acquisition means acquired from the information processing apparatus and the e-mail address acquisition means, the plurality of e-mail addresses are acquired. It has a display control means for displaying one or more e-mail addresses among the e-mail addresses in the address setting field of the screen.

<Communication between IC card and short-range communication unit>
FIG. 10 shows a conceptual diagram of a scene in which a user causes an electronic blackboard 2 to read an IC card 3, and FIG. 11 is an example of a screen displayed on the display 220 of the electronic blackboard 2. As shown in FIG. 10, the electronic blackboard 2 has a power switch 222 and a short-range communication unit 219. When the user presses the power switch 222 of the electronic blackboard 2, the display control unit 24 displays the login screen 170 on the display 220 as shown in FIG. 11A.

Next, as shown in FIG. 10, when the user A brings his / her IC card 3 close to (holds) the short-range communication unit 219 of the electronic blackboard 2, the authentication process described later is started. If the authentication is successful, as shown in FIG. 11B, the display control unit 24 may display a ticker 191 such as "Welcome, Mr. Kato" on the display 220 and start drawing. Show that you can. The character "Kato" is stored in the terminal management DB 5001.

In the present embodiment, the user also holds the IC card 3 close to (holds) the short-range communication unit 219 even when the user selects a destination when transmitting an e-mail.

<Send email>
Subsequently, with reference to FIG. 12, the setting of the destination at the time of sending the e-mail will be described. FIG. 12 is a diagram showing an example of a destination setting screen 270 displayed on the display 220 when an e-mail is transmitted. After the user A advances the conference while drawing on the electronic blackboard 2 using the electronic pen 2500, the user A presses the "menu" button 231 shown in FIG. 7B with the electronic pen 2500 or the like. By pressing the button and then pressing the "send mail" button 237, the display control unit 24 displays the destination setting screen 270 shown in FIG. 12A on the display 220.

As shown in FIG. 12A, when the destination setting screen 270 is displayed, the e-mail address of the logged-in user A is displayed in the address setting field 274 from the beginning. You may also select the "Direct Input" tab 272 and enter your own e-mail address with an electronic pen 2500 or the like.

When the destination setting screen 270 is displayed, the setting unit 27 sets the e-mail address of the group 1 in the address setting field 274. Therefore, his / her e-mail address is registered in Group 1. In other words, the administrator or the like registers the user's e-mail address in group 1. The e-mail address of the self may be managed separately from the group, and in that case, the e-mail address managed as the e-mail address of the self is set in the address setting field 274 by the setting unit 27.

When the user A wants to send an e-mail address to another e-mail address, the user A brings his / her IC card 3 close to (holds) the short-range communication unit 219 of the electronic blackboard 2. As a result, the determination unit 25 detects that the IC card 3 has been read again, and the setting unit 27 acquires the e-mail address of the group 2 from the destination management table acquired from the destination management server 6. Then, the e-mail address of the group 1 is deleted, and the e-mail address of the group 2 is set in the address setting field 274. As shown in FIG. 12B, the group 2 e-mail address is displayed in the address setting field 274.

Further, the same applies when the user A brings his / her IC card 3 close to (holds) the short-range communication unit 219 of the electronic blackboard 2, and the determination unit 25 detects that the IC card 3 has been read again. Then, the setting unit 27 acquires the e-mail address of the group 3 from the destination management table acquired from the destination management server 6. Then, the e-mail address of the group 2 is deleted, and the e-mail address of the group 3 is set in the address setting field 274. As shown in FIG. 12C, the group 3 e-mail address is displayed in the address setting field 274.
In this way, each time the user A brings his / her IC card 3 close to (holds) the short-range communication unit 219 of the electronic blackboard 2, the e-mail address set in the address setting field 274 is changed from group 1 to group 2. → It switches like Group 3 ... When there is only group 3 registered in the destination management DB 6001, user A brings his / her IC card 3 close to (holds) the short-range communication unit 219 while the group 3 is displayed, and the electronic group 1 is electronically displayed. The email address is displayed.

<Operation procedure>
FIG. 13 is an example of a sequence diagram showing the operation of the electronic blackboard 2 until the electronic blackboard 2 transmits an e-mail. As shown in FIG. 11A, the process of FIG. 13 will be described as starting from the state where the login screen 170 is displayed on the display 220.

S11: When the user A brings his / her IC card 3 close to (holds) the short-range communication unit 219, the acquisition / provision unit 28 of the electronic blackboard 2 moves from the acquisition / provision unit 38 of the IC card 3 to the terminal of the IC card 3. Get an ID.

S12: Then, the transmission / reception unit 21 of the electronic blackboard 2 transmits a login authentication request to the terminal management server 5. The login authentication request includes the terminal ID read from the IC card 3. As a result, the transmission / reception unit 51 of the terminal management server 5 receives the login authentication request.

S13: Next, the authentication unit 52 of the terminal management server 5 performs login authentication of the IC card 3 using the terminal ID. Specifically, the storage / reading processing unit 59 uses the terminal ID received in step S12 as a search key to search the terminal management table for the user ID corresponding to the terminal ID. If there is a corresponding user ID, the authentication unit 52 determines that it is a legitimate IC card 3 (terminal ID). If there is no corresponding user ID, the authentication unit 52 determines that the IC card 3 (terminal ID) is not valid.

S14: Next, the transmission / reception unit 51 of the terminal management server 5 transmits the authentication result to the electronic blackboard 2. When the authentication unit 52 determines that the IC card 3 is legitimate (when the authentication is successful), the authentication result includes information indicating legitimacy, a user ID, and a user name. Further, when the authentication unit 52 determines that the IC card 3 is not valid (when the authentication fails), the authentication result includes information indicating that the IC card 3 is not valid. As a result, the transmission / reception unit 21 of the electronic blackboard 2 receives the authentication result.

S15: Next, the electronic blackboard 2 performs processing based on the authentication result. The process based on the authentication result is a process of displaying an error screen when the authentication includes the fact that the authentication is not valid. When the authentication includes the fact that it is valid, it is a process of identifying a user or displaying the above ticker 191. Further, the fact that the authentication is valid is stored in the storage unit 2000. Hereafter, the explanation will be continued as to the case where it is legitimate.

S16: The transmission / reception unit 21 of the electronic blackboard 2 transmits an e-mail address transmission request to the destination management server 6. This transmission request includes a user ID (which may be any information that identifies or identifies the user, and may be a terminal ID) received in step S14. As a result, the transmission / reception unit 61 of the destination management server 6 receives the transmission request of the e-mail address.

S17: Next, in the destination management server 6, the storage / reading processing unit 69 reads out the corresponding e-mail address by searching the destination management table using the user ID received in step S37 as a search key.

S18: Then, the transmission / reception unit 61 transmits the request result to the electronic blackboard 2 as a response to the transmission request of the e-mail address. The request result includes the email address read in step S17. As a result, the transmission / reception unit 21 of the electronic blackboard 2 receives the request result.

S19: The storage / reading processing unit 29 of the electronic blackboard 2 stores the e-mail address included in the request result in the storage unit 2000 in association with the terminal ID. The terminal ID is stored to identify the owner of this e-mail address and prevent others from using the e-mail address. It may be associated with the user ID and stored.

S20: Next, the setting unit 27 of the electronic blackboard 2 sets the sender and destination of the e-mail. The sender sets the user's e-mail address or the e-mail address of the electronic blackboard 2. The sender's e-mail address is fixed no matter how many times the IC card 3 communicates with the short-range communication unit 219.

Further, the setting unit 27 sets the e-mail address of the group 1 in the address setting field 274. At this time, the setting unit 27 stores the last set group ID in the storage unit 2000. Next, when the IC card 3 is brought close to the short-range communication unit 219, the e-mail address of the next group ID is set in the address setting field 274. As shown in FIG. 12A, the display control unit 24 displays the e-mail address (e-mail address of the logged-in user) included in the group 1 in the address setting field 274.

S21: Next, when the user A brings his / her IC card 3 close to (holds) the short-range communication unit 219 again, the acquisition / provision unit 28 of the electronic blackboard 2 is transferred from the acquisition / provision unit 38 of the IC card 3. Acquire the terminal ID of the IC card 3.

S22: The determination unit 25 detects that the terminal ID has been read from the IC card 3. Further, since the storage unit 2000 stores that the authentication is valid, the determination unit 25 determines that the authentication process is unnecessary. Therefore, the determination unit 25 sends the terminal ID to the storage / reading processing unit 29, and determines whether or not there is an e-mail address associated with the terminal ID. When the e-mail address is stored in the storage unit 2000 in association with the terminal ID acquired in step S21, the e-mail address is acquired. When the e-mail address is not stored in the storage unit 2000 in association with the terminal ID acquired in step S21, the determination unit 25 determines that the user A cannot use the e-mail address stored in the storage unit 2000. to decide. In this embodiment, it is assumed that the e-mail address is stored in the storage unit 2000 in association with the terminal ID acquired in step S21.

S23: Since the group ID last set in the address setting field 274 stored in the storage unit 2000 is 1, the setting unit 27 sets the address of the e-mail address included in the next group, group 2. Set in column 274. The setting unit 27 stores the last set group ID in the storage unit 2000. As shown in FIG. 12B, the display control unit 24 displays the e-mail address included in the group 2 in the address setting field 274.

S24 to S26: After that, each time the user A brings his / her IC card 3 close to (holds) the short-range communication unit 219 again, the setting unit 27 sets the e-mail address of the next group. Set in column 274. As a result, the display control unit 24 displays the e-mail address included in the group 3 in the address setting field 274 as shown in FIG. 12 (C).

S27: Subsequently, when the reception unit 22 of the electronic blackboard 2 receives the pressing of the "send" button 277 by the user A, the creation unit 26a of the electronic blackboard 2 is converted into a PDF format from the drawing image data in the bitmap format. Create image data (transmission data) of.

S28: Then, the e-mail transmission unit 27-2 transmits an e-mail to which the image data created in step S27 is attached to the mail server 7. As a result, the transmission / reception unit 71 of the mail server 7 receives the e-mail to which the image data in PDF format is attached. At this time, the e-mail includes the e-mail address of the logged-in user A as the sender and the e-mail address set in FIG. 12 (C) as the destination (destination) (for example, the e-mails of PCs 10a to 10d). Address) is included.

S29 to S32: The transmission / reception unit 71 of the mail server 7 transmits an e-mail to which the image data in PDF format is attached to the PCs 10a to 10d. At this time, the e-mail includes the e-mail address of the sender who is the user A, and the e-mail addresses of the destination PCs 10a to 10d set in step S26. As a result, the PCs 10a to 10d each receive an e-mail with image data in PDF format attached.

<Processing when acquiring the terminal ID>
A process when the electronic blackboard 2 acquires the terminal ID will be described with reference to FIG. FIG. 14 is an example of a flowchart showing a procedure in which the electronic blackboard 2 acquires a terminal ID from the IC card 3 and displays an e-mail address. It should be noted that the description of FIG. 14 partially overlaps with the description of FIG.

First, FIG. 14A describes a process when the user brings the IC card 3 close to (holds) the short-range communication unit 219 for authentication.

It is assumed that the authentication by the authentication unit 52 of the terminal management server 5 is successful by acquiring the terminal ID by the acquisition / providing unit 28 of the electronic blackboard 2 (S101).

As a result, the storage / reading processing unit 29 of the electronic blackboard 2 stores the e-mail address in the storage unit 2000 in association with the terminal ID (S102).

Further, when the user A presses the "send mail" button 237 to display the destination setting screen 270 on the display 220, the setting unit 27 sets the e-mail address of the group 1 in the address setting field 274, so that it can be stored and read. The processing unit 29 stores the group ID of group 1 in the storage unit 2000 (S103). Immediately after the "send mail" button 237 is pressed, immediately after the destination setting screen 270 is displayed, or immediately after the authentication is successful, the group ID to be displayed and saved may be predetermined and is not group 1. May be good.

Next, the display control unit 24 displays the e-mail address of the group 1 in the address setting field 274 (S104).

Next, FIG. 14B describes a process when the user further brings the IC card 3 closer to (holds) the short-range communication unit 219 after the destination setting screen 270 is displayed. The process of FIG. 14B is periodically and repeatedly executed. Alternatively, the process of FIG. 14B may be started with the acquisition of the terminal ID as a trigger.

The determination unit 25 determines whether or not the terminal ID has been acquired (S201). If the determination in step S201 is No, the process of FIG. 14B ends.

If the determination in step S201 is Yes, the determination unit 25 determines whether or not the terminal ID acquired by the acquisition / provision unit 28 matches the terminal ID stored in the storage unit 2000 (S202).

If the determination in step S202 is No, the e-mail address of the storage unit 2000 should not be displayed, so the process of FIG. 14B ends.

If the determination in step S202 is Yes, the storage / reading processing unit 29 acquires the group ID stored in the storage unit 2000 (S203).

Then, in order to display the e-mail address of the next group ID, the setting unit 27 increases the acquired group ID by one (S204). For example, if the group ID of the storage unit 2000 is 1, the group ID is set to 2.

Then, it is determined whether or not the e-mail address stored in the storage unit 2000 has the group ID obtained in step S204 (S205).

If the determination in step S205 is No, the setting unit 27 returns the group ID to 1, which is the initial value (S206). As a result, the display control unit 24 of the electronic blackboard 2 can display the e-mail address of the group 1 again.

If the determination in step S205 is Yes, or following step S206, the setting unit 27 sets the e-mail address of the group specified by the group ID in the address setting field 274, so that the storage / reading processing unit 29 stores. The group ID is stored in the unit 2000 (S207).

The display control unit 24 displays the set e-mail address in the address setting field 274 (S208).

By such processing, each time the user brings the IC card 3 close to (holds) the short-range communication unit 219, the e-mail address to be displayed in the address setting field 274 is switched in the predetermined order of ascending order of the group ID. Can be done. The order of switching the group IDs may be descending or random (may be random). The ascending order means that the dates of the data are rearranged from the oldest to the newest, from the smallest to the largest amount of data, or the letters in the order of the Japanese syllabary, and the alphabet in the direction from A to Z. The descending order is to sort the data in order from the data with the largest value. If you arrange them in descending order according to the date and time data, they will be arranged in order from the new date and time, and according to the character string such as the title, the one with the largest character code will come to the top.

Further, if only one e-mail address belongs to each group, the user can switch and display the e-mail addresses one by one.

<< Displaying e-mail addresses using the display order table >>
Instead of switching the e-mail addresses in ascending or descending order of the group ID, the display order of the e-mail addresses may be switched using the display order table. In this case, the destination management DB 6001 stores the following display order table.

Table 1 shows an example of a display order table. In the display order table, display order information of the group ID (e-mail address specified by) is registered in association with the user ID. The display order information is information that specifies the display order of the e-mail addresses included in the group. In Table 1, "1 → 2 → 3" is the display order information (returns to 1 after 3). Since the display order table is downloaded to the electronic blackboard 2 together with the e-mail address, the setting unit 27 can refer to the display order table and specify the group of e-mail addresses to be set next in the address setting field 274.

FIG. 15 is an example of a flowchart showing a procedure in which the electronic blackboard 2 acquires a terminal ID and displays an e-mail address. In the description of FIG. 15, the difference from FIG. 14 will be mainly described.

In the process of FIG. 15 (A), the process of steps S101 and S102 may be the same as that of FIG. 14 (A). In step S103-2, since the setting unit 27 sets the e-mail address of the group 3 having the display order 1 in the display order table in the address setting field 274, the storage / reading processing unit 29 sets the display order 1 in the display order table. The group ID (group 3) of the above is stored in the storage unit 2000.

Further, the display control unit 24 displays the e-mail address of the group ID (group 3) whose display order is 1 in the address setting field 274 (S104-2).

In the process of FIG. 15 (B), the process of steps S201 to S203 may be the same as that of FIG. 14 (B). In step S204-2, the setting unit 27 determines the next group ID of the group ID acquired from the storage unit 2000 from the display order table (S204-2). When the group ID acquired from the storage unit 2000 is the last display order of the display order table, the group ID whose display order is 1 is specified.

The processing of steps S207 and S208 may be the same as in FIG. 14B.

By doing so, the user can display the group IDs in any order. The user can edit the display order of his / her own address management table from PC10 or the like. Further, for example, if the setting unit 27 requests the destination management server 6 to set the display order 1 of the display order table to the group ID when the user sends the e-mail address, the group IDs are displayed in the order frequently used by the user. The sequence table is sorted.

<< Add and display e-mail address >>
In the explanation of FIG. 14, each time the user brings the IC card 3 close to (holds) the short-range communication unit 219, the e-mail address to be displayed in the address setting field 274 is switched, but the user brings the IC card 3 close to the user. An e-mail address to be displayed in the address setting field 274 may be added each time the distance communication unit 219 is brought close to (held).

Since the destination management table in FIG. 9B is divided into groups and duplicate e-mail addresses are also registered in each group, the e-mail addresses are individually displayed in order to be additionally displayed in the address setting field 274. It should be selected. Therefore, for example, it is preferable to be able to set a mode so that the e-mail address setting method can be selected from either "switching mode" or "additional mode". In the add mode, each e-mail address is sorted one by one (either ascending or descending order is acceptable), and each time the user brings the IC card 3 close to (holds) the short-range communication unit 219, the setting unit 27 Adds an e-mail address to the address setting field 274 and sets it. It is assumed that your e-mail address is registered at the beginning of a series of e-mail addresses.

FIG. 16 is an example of a flowchart showing a procedure in which the electronic blackboard 2 acquires a terminal ID and displays an e-mail address. In the description of FIG. 16, the difference from FIG. 14 will be mainly described.

In the process of FIG. 16 (A), the process of steps S101 and S102 may be the same as that of FIG. 14 (A). In step S103-3, the setting unit 27 sets the first (own) e-mail address in the address setting field 274 among the series of e-mail addresses sorted one by one, so that the storage / reading processing unit 29 Stores the first e-mail address in storage 2000.

Next, in step S104-3, the display control unit 24 displays its e-mail address in the address setting field 274.

In the process of FIG. 16 (b), the process of steps S201 to S202 may be the same as that of FIG. 14 (b). It is assumed that the user is set to "additional mode". In step S203-3, the storage / reading processing unit 29 acquires the e-mail address stored in the storage unit 2000 and stored in step S103-3.

Then, in order to display the next e-mail address, the setting unit 27 acquires the next e-mail address from the series of e-mail addresses sorted one by one (S204-3). This next e-mail address is the next e-mail address of the e-mail address stored in the storage unit 2000 in step S103-3.

If there is no next e-mail address (No in S205-3), the e-mail address cannot be added, so the process of FIG. 16 (b) ends.

When there is the next e-mail address (No of S205-3), the setting unit 27 adds the next e-mail address to the address setting field 274 and sets it, and the storage / reading processing unit 29 electronically sets the storage unit 2000. The e-mail address is saved (S207-3), and the display control unit 24 adds and displays the e-mail address (S208-3).

By doing so, the user can add and set the e-mail address in the address setting field 274. Although FIG. 16 has described an example of adding e-mail addresses one by one, it is also possible to add e-mail addresses for each group. However, in this case, it is preferable that the e-mail addresses belonging to the group are adjusted so as not to be duplicated.

<Summary>
As described above, in the communication system 1 of the present embodiment, the user A communicates one IC card 3 with the short-range communication unit 219, so that the user A can electronically send one or a group from a plurality of e-mail addresses. You can select an email address and improve operability. Further, every time the user A communicates one IC card 3 with the short-range communication unit 219, the e-mail address is already replaced in the address setting field 274 to display another e-mail address, or the address setting field 274. You can add and display your e-mail address in.

<Other application examples>
Although the best mode for carrying out the present invention has been described above with reference to examples, the present invention is not limited to these examples, and various modifications are made without departing from the gist of the present invention. And substitutions can be made.

<< Certification Department >>
Instead of authenticating by the authentication unit 52, an authentication server may be used externally. An example of an authentication server is a Lightweight Directory Access Protocol (LDAP) server. LDAP is a protocol for connecting to a directory service that manages information such as network devices and users. The directory service is a service that centrally manages various information existing in the network and provides functions such as search. The client (electronic blackboard 2 in this embodiment) connects to the LDAP server using TCP port 389 (default port number), and is composed of attributes (department, personal name, etc. in the case of an in-house list). Perform operations such as searching, adding, deleting, and modifying entries (a group of related attributes).

For example, if the user IDs and passwords of a plurality of services are collectively registered as attributes of one user ID, each service can perform authentication work by referring only to the LDAP server. Since the administrator can also manage the information centrally, it is possible to reduce the trouble of changing the user information in each service directory.

LDAP servers include open software such as OpenLDAP and commercial software represented by Microsoft's Active Directory (registered trademark).

Table 2 shows an example of the authentication device setting information set in the authentication server.
-Preferred server address: The IP address of the authentication server.
-Alternative server address 1, 2: The IP address of the alternative authentication device that substitutes for the authentication server while the authentication server 0 is stopped.
-Port number: The TCP port number of the authentication server. The specified value of LDAP is 389.
-User name: A user name that accesses the authentication server (identification information of a user in the company, etc., and has the same function as the user ID).
-Password: Information that is normally kept secret for accessing the authentication server.
-Identification name (DN): A name for identifying an object by LDAP. By associating the identification name (DN) with the object in a predetermined format, the client can acquire the object by the identification name (DN).
-Card ID: IC card identification information. The IC card may be identified not only by the card ID but also by writing information for identifying the IC card by an IC card reader or the like in the storage area of the IC card. Information that identifies an IC card, including a card ID, is called card information.
-Account ID: Corresponds to the user's identification information in the cloud service. For example, as a cloud service, a service for schedule management that enables reservations for meetings and the like is known. Since the account ID, the user name (password), and the card ID are associated with each other, the identification information of the user in the company and the identification information of the user of the cloud service can be exchanged with each other.

<< If there are multiple terminal management servers, destination management servers, and mail servers >>
For example, as shown in FIG. 17, the communication system 1 may have a plurality of terminal management servers 5, a destination management server 6, and a mail server 7. FIG. 17 shows another example of the schematic configuration diagram of the communication system 1. In addition, FIG. 17 mainly explains the difference from FIG. 2. The communication system of FIG. 17 has a plurality of terminal management servers 5, a destination management server 6, and a mail server 7. In the communication system 1 having such a configuration, any terminal management server 5, destination management server 6, or mail server 7 may be provided with the function of the present embodiment.

Further, the system configuration in which the electronic blackboard 2 described in the present embodiment is connected to the terminal management server 5, the destination management server 6, and the mail server 7 is an example, and various system configuration examples are available depending on the application and purpose. Needless to say, there is.

<< Electronic blackboard with scanner function >>
Although the touch panel type electronic blackboard 2 has been described in the present embodiment, the electronic blackboard 2 capable of transmitting e-mail is not limited to the one provided with the touch panel.

FIG. 18 shows an external view of an electronic blackboard 2 capable of transmitting board writing information by e-mail. The electronic blackboard 2 has a normal whiteboard 450, which is made of a cloth-like bendable material and has a roll hidden in the right bezel and a roll hidden in the left bezel. Is being circulated. It also has a line sensor (scanner) between the bezel on the right side and the bezel on the left side.

When the user holds the IC card 3 over the short-range communication unit 219, the roll rotates and the whiteboard moves to the right. When moving, the scanner reads the board information. When the roll is rotated by one side, the electronic blackboard 2 sends the blackboard information (image data) to the destination by the e-mail associated with the card ID.

When the user continuously reads the IC card 3, the electronic blackboard 2 remembers the number of times and sends an e-mail to the e-mail address of the group ID according to the number of times. The scanned range is for one surface regardless of the number of times the IC card 3 is read.

<< Another example of the configuration of an electronic blackboard >>
Although the electronic blackboard 2 of the present embodiment is described as having a large touch panel, the electronic blackboard 2 is not limited to the one having a touch panel.

FIG. 19 is a diagram showing another configuration example of the electronic blackboard 2. In FIG. 19, the projector 4110 is installed on the upper side of the normal white boat 4130. This projector 4110 corresponds to the electronic blackboard 2. The normal white boat 4130 is not a flat panel display integrated with a touch panel, but a white boat that the user directly handwrites with a marker. The white boat may be a blackboard, and may be a flat surface large enough to project an image.

The projector 4110 has an ultra-short focus optical system, and can project an image with little distortion from about 10 cm onto the white boat 4130. This image may be transmitted from the PC 400-1 connected wirelessly or by wire, or may be stored by the projector 4110.

The user writes on the white boat 4130 using the dedicated electronic pen 2500. The electronic pen 2500 has, for example, a light emitting portion at its tip, which turns on and emits light when the user presses it against the white boat 4130 for handwriting. Since the wavelength of light is near infrared or infrared, it is invisible to the user's eyes. The projector 4110 has a camera, captures a light emitting unit, analyzes the image, and identifies the direction of the electronic pen 2500. Further, the electronic pen 2500 emits a sound wave together with light emission, and the projector 4110 calculates the distance from the arrival time of the sound wave. The position of the electronic pen 2500 can be specified by the direction and the distance. A stroke is drawn (projected) at the position of the electronic pen 2500.

Since the projector 4110 projects the menu 4300, when the user presses a button with the electronic pen 2500, the projector 4110 identifies the position of the electronic pen 2500 and the button pressed by the ON signal of the switch. For example, when the save button 4310 is pressed, the stroke (a set of coordinates) handwritten by the user is saved by the projector 4110. The projector 4110 stores handwritten information in a predetermined server 4120, a USB memory 2600, or the like. Handwritten information is stored page by page. Since the coordinates are saved instead of the image data, the user can edit them again.

When applied to the present embodiment, the projector 4110 captures an image from an image interface and operates or does not operate depending on whether or not the electronic pen 2500 is used for handwriting (whether or not light emission is present and whether or not communication is performed). to decide. Therefore, even in the electronic blackboard 2 in which the projector 4110 is used, it is possible to suppress the deterioration of the handwriting performance when displaying the image from the PC400-1.
