The posting unit 115 transmits the posting data (selected image data and message) and the display time limit, and the Web session ID 604 among the input contents of the user from the transmission / reception device 104A to the display terminal 2 as a posting request ( Step S802).

  The posting acceptance unit 206 receives a posting request via the transmission / reception device 104B of the display terminal 2, and the session management unit 208 checks the Web session ID 604. If the Web session ID 604 is correct, the non-access elapsed time 603 is reset to 0 (step S804).

  The posting acceptance unit 206 stores the image data in the content DB 202 and updates the content management table 501. At this time, the posting acceptance unit 206 generates a random ID as the content ID 502. The user ID 111 is acquired from the session management table 601. The display deadline is included in the posting request.

  Next, the posting acceptance unit 206 displays the image data, the message, and the content ID 502 on the electronic bulletin board through the display device 212, and returns a posting completion notification (step S806).

  The posting unit 115 transmits a Web session ID 604 as a logout request (step S808). The content management unit 205 receives the logout request, the session management unit 208 verifies the web session ID 604 (step S810), and deletes the corresponding entry from the session management table 601 if the web session ID 604 is valid. Then, a logout completion notice is returned (step S812).

  The content management unit 205 displays a logout completion notification from the input / output device 103 to the user (step S814). The time limit management unit 213 deletes the content when the display time limit stored in the content DB 202 is reached. At this time, if comment data written for the content exists in the content DB 202, the comment data is transmitted from the transmission / reception device 104B as an e-mail addressed to the e-mail address acquired from the user information DB 204. As a result, the comment data for the content is transmitted to the content contributor (steps S816 and S818).

  The mail receiving unit 113 displays the content of the result mail from the input / output device 103 to the user (step S820).

  Next, referring to the flowchart of FIG. 9, a procedure for writing comments on content by a viewer will be described. It is assumed that login has been completed according to the procedure from step S702 to step S722.

  The user selects comment writing 1102 through the input / output device 103 on the top screen displayed in step S722.

  The comment writing unit 116 displays a content ID 502 and a comment content input field. FIG. 13 shows a display example.

  The user executes content selection processing (step S902) and comment creation processing (step S904). Specifically, the user inputs the content ID 502 of the content to be commented into the display area 1301, enters the comment content into the display area 1302, and selects the send button 1303. Here, what is displayed on the display device 212 of the display terminal 2 is input as the content ID 502. Thereby, the comment writing unit 116 transmits the Web session ID 604, the content ID 502, and the comment data from the transmission / reception device 104A as a comment writing request (step S904).

  The comment accepting unit 207 receives a comment writing request via the transmission / reception device 104B, and the session management unit 208 collates the Web session ID 604. If the Web session ID 604 is correct, the session management unit 208 resets the non-access elapsed time 603 to 0 (step S906).

  The comment receiving unit 207 adds the comment data to the content data corresponding to the content ID 502 corresponding to the received content ID in the content DB 202, and then displays the comment data on the electronic bulletin board through the display device 212. Next, the comment receiving unit 207 returns a comment writing completion notification (step S908).

  Steps S910 to S916 executed below are the same as Steps S808 to S814 described above, and thus the description thereof is omitted.

  Here, in the short-range communication device 102B of the mobile terminal 1, when only the response message is received from one display terminal 2 ′, that is, the mobile terminal 1 is only in the communication zone of one display terminal 2 ′. If entered, the login request unit 117 extracts the user ID 111 and password 112 from the terminal possession information DB 110 and outputs a login request including them and the display terminal ID from the short-range communication device 102A. Thereby, even if a user does not designate a display terminal, he can use display terminal 2 'which is the shortest distance from his position as a display terminal on which his post data or a post comment is displayed.

  On the other hand, when the short-range communication device 102B of the mobile terminal 1 receives response messages from the plurality of display terminals 2 ′, that is, when the mobile terminal 1 is in the communication zone of the plurality of display terminals 2 ′. The login request unit 117 displays a list of display terminal IDs included in those response messages on the input / output device 103. When the user selects one display terminal ID from the list on the input / output device 103 while confirming the display terminal ID written on each peripheral display terminal 2 ′, the login request unit 117 displays the user ID 111. And the password 112 are extracted from the terminal possession information DB 110, and a login request including them and the display terminal ID selected by the user is output from the short-range communication device 102A. As a result, when a plurality of display terminals 2 ′ are present at a short distance from the user, the user selects a display terminal from among them and displays his / her own post data or post comments. Display terminal can be selected (S1900).

  In this manner, when the short-distance communication device 102B of the display terminal 2 ′ waiting for the login request receives a login request including its own display terminal ID, the login request transfer unit 1504 displays the display terminal from the storage device 107C. The ID 1502 is read, and an authentication request addressed to the main server 7 including the display terminal ID and information (user ID 111 and password 112) in the login request is output from the transmission / reception device 104B (step S1902).

  When the transmission / reception device 104C of the main server 7 receives the authentication request from the display terminal 2 ′ (S1904), the login processing unit 1611 uses the same combination as the user ID and the password 112 included in the authentication request. The user information table in the user information DB 204 ′ is searched. As a result, the login processing unit 1611 authenticates the user of the mobile terminal 1 that is the source of the login request (S1904). As a result, when the corresponding combination exists in the user information table, that is, when the user authentication is successful, the session management unit 1610 displays the randomly generated ID and the display included in the authentication request. A new entry including the terminal ID, the user ID included in the authentication request, and the initial value “0” of the non-access elapsed time as the session ID 1802, the display terminal ID 1806, the user ID 1803, and the non-access elapsed time 1804 is included. Registration in the session management table 1801 (S1906).

  Thereafter, the session management unit 1610 sequentially updates the non-access elapsed time 1804 in the session management table 1801 with the count value while counting the elapsed time, similarly to the session management unit 208 of FIG. If there is no access from the mobile terminal 1 even if 1804 reaches a certain value, the user is forcibly logged out by deleting the corresponding entry from the session management table 180101.

  Now, after the session management unit 1610 registers a new entry in the session management table 1801, on the one hand, the login processing unit 1611 generates the session ID generated in S1906 and the URL of the main server program 1601 in the main server 7. Is returned to the display terminal 2 ′ (S1907). Here, the URL of the main server program 1601 of the main server 7 is included in the session information. However, if the resource is accessed by the mobile terminal 1 via the mobile network 4 and the network 3, the URL of any resource is It may be included in the session information.

  When the transmission / reception device 104B of the display terminal 2 ′ receives session information from the main server 7, the login request transfer unit 1504 causes the short-range communication device 102B to output the session information. Thereby, the session information from the main server 7 is transferred to the mobile terminal 1 that is the origin of the login request (S1908).

  When the session information is received by the short-range communication device 102B of the mobile terminal 1, the login request unit 117 stores the session information in the work memory (S1909), as in S712 and S714 described above. A bulletin board use request for the resource indicated by the URL included in the session information is output from the transmission / reception device 104B (S1910). This bulletin board use request includes the session ID included in the session information.

  When the bulletin board use request is received by the transmitting / receiving device 104C of the main server 7, the session management unit 1610 manages the session ID 1802 that is the same as the session ID included in the bulletin board use request in response to the bulletin board use request. Search in table 1801. If there is an entry including the corresponding session ID 1802, the session management unit 1610 generates a random ID and registers this ID as the Web session ID 1805 of the entry (S1912).

  Thereafter, the login processing unit 1611 sends the Web session information including the Web session ID generated by the session management unit 1610 and the document for displaying the top screen of FIG. 11 to the mobile terminal 1 via the network 3 and the mobile network 4. In order to return it, the data is output from the transmitting / receiving device 104C (S1913).

  When the Web session information and the document from the main server 7 are received by the transmission / reception device 104A of the mobile terminal 1, the login request unit 117 displays the Web session included in the Web session information as in S720 and S722 described above. After saving the ID in the work memory (S1914), the posting browsing processing unit 120 displays the top screen of FIG. 11 on the input / output device 103 based on the document (S1915).

  Next, the content posting process of the user (contributor) of the portable terminal 1 in the electronic bulletin board system of FIG. 14 will be described with reference to FIG. The following processing is processing after S1915 in FIG.
