PROBLEM TO BE SOLVED: To generate a pseudo-rewriting action of a color developing picture pattern in an information displaying medium provided with a reversible recording region which is changed to a color developed condition and a color erased condition and displays the color developing picture pattern which can be rewritten by the color developed condition. SOLUTION: A color print part 9 consisting of coloring patterns 8 with a plurality of colors is formed in the reversible recording region 4 and by selectively displaying several kinds of color developing picture patterns 10a, 10b and 10c provided with color erasing parts 11 with mutually different shapes at a position coinciding with the color print part 9, the color of a colored pattern 8 is displayed on the color erasing part 11 of each of color developing picture patterns 10a, 10b and 10c. |
