Disclosed is a simple, inexpensive handwriting input board whereby handwritten characters or the like can be erased, and furthermore, erased characters or the like can be stored. The handwriting input board is provided with: a display panel provided with a writing area in which dot patterns, in which coordinates and/or code values are repeatedly defined, are arranged; and a scanner pen which can be used to draw on or touch the display panel to draw a trail. The scanner pen is provided with: an optical reading unit that optically reads the dot pattern provided on the display panel; and a dot code analysis unit. When the scanner pen is used to draw on or touch the display panel, the scanner pen sequentially images the dot pattern, the dot code analysis unit analyzes the dot pattern and outputs coordinates and/or code values, and a trail is displayed visibly on the display panel. The handwriting input board is also provided with an erasure unit for erasing the displayed trail. |
