<p>PURPOSE:To improve the efficiency of a normal meeting or a review talk by providing a means displaying picture information, simultaneously scanning picture information displayed on a board and that newly drawn on the board by means of a scanner and copying or transferring picture information as the same screen. CONSTITUTION:Coordinates and a picture 10 on the board 1 are obtained by projecting the previously prepared picture of the screen on the board 1. A picture 11 is a one additionally drawn on the board 1 from the outside with the picture 10 as an original when a meeting is held. Accordingly, in this state, the pictures 10 and 11 can be recognized as the picture on the board 1 and as the same screen. For copying, first the scanner 2 scans the board 1. It optically senses the picture on the board 1, and converts the coordinates and the pictures 10 and 11 on the board 1 into an electrical signal. A transfer processor 17 sends the transmitted picture information to a transfer head 19, whereby the pictures on the board 1 are all transferred on a transfer paper 20.</p> |
