<p>PURPOSE:To project a colored chart even if an OHP sheet is not colored by controlling a color liquid crystal display plate so that a graphic in a position specified by a graphic specification means and a coordinate detection means is colored with a color specified by a color specification means. CONSTITUTION:The color liquid crystal display plate 4 is arranged in contact with a stage glass 3 between a light source 2 and the stage glass 3. A touch panel 5a consisting of a transparent pressure sensitive film and the coordinate specification means 5 constituted of a coordinate detector are provided on the stage glass 3. A graphic specification switch included in the graphic specification means 6 for specifying the shape of a colored range, a color specification switch included in the color specification means 7 for specifying the color of a graphic specified by the graphic specification means 6 and a clear switch are arranged at the side of the stage glass part. The color liquid crystal display plate 4, the coordinate detection means 5, the graphic specification means 6 and the color specification means 7 are connected to a liquid crystal control means 8. Thus, a coloring operation to the OHP sheet is not needed and the color and the colored range can be freely changed while projecting the chart.</p> |
