<p>PROBLEM TO BE SOLVED: To provide the electronic blackboard whose installation location is not limited in the case of connecting the electronic blackboard TO A LAN. SOLUTION: An optical scanner 220 reads image information on a roll sheet of a blackboard section 200 and stores it to a microcomputer system 170. A radio section 120 generates a call between the electronic blackboard being a radio terminal and a LAN-CS base station 30 under the control of the microcomputer system 170 and the LAN-CS base station 30 generates a call with a terminal 300 to set a data communication path between the electronic blackboard and the terminal 300. A data communication section 140 generates a link of a data channel with the terminal 300 and the image stored in the microcomputer system 170 is sent to the terminal 300 via this link.</p> |
