Then, the size and position of the image drawing area 34 are determined (S303).

  Next, the drawing means 25 deletes the reduced window 40 and redisplays the standard window 30 (S304). The drawing unit 25 displays the menu bar area 31 and the tool bar area 32 with reference to the upper left vertex 30a of the window 30 (S305). At this time, the size of the menu bar area 31 and the tool bar area 32 is not changed as described above.

  The drawing unit 25 displays the submenu area 33 according to the size and position of the submenu area 33 determined in S302 (S306).

  Next, the drawing means 25 redisplays the drawing image stored in the drawing image storage means 20d in the image drawing area 34 with reference to the upper left vertex 34a of the image drawing area 34 determined in S301 (S307). .

  As described above, in the interactive board system according to the present embodiment, when the standard state window 30 of FIG. 3A is displayed on the board 1, the electronic pen 4 is operated on the board 1 and changed.
