PURPOSE: A white board is provided to record contents with a water-based pen (alias, Magic Pen) on a surface of the board in a lecture room or meeting room. The contents recorded on a screen of the white board are automatically copied or saved. The contents is accurately transferred to attended people without any special speakers, and the lecture or the publication is repeatedly listened or saved. CONSTITUTION: A white board is provided for repeatedly listening or saving lecture or publication contents by recording. A writing device has two screens with wrapping in an endless track-typed on a couple of rollers installed in the both sides of a frame for rotating. A driving device changes the two screens by rotating the rollers. A lightening device is installed inside the frame to investigate the light toward the screen recorded contents. A reflecting device reflects the contents on the screen lighted by the lightening device toward a parallel direction. A CCD scanning device reads data by photoelectric-converting of the contents reflected by the reflecting device. A printing device outputs the data received from the CCD scanning device. More than one speaker generates a voice signal by receiving a signal of the CCD scanning device. And a controlling section controls each part of above.
