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 saved. Said handwriting input board is provided with: a display panel provided with a writing region in which a dot pattern, in which coordinates and/or code values are defined cyclically, is arranged; and a scanner pen which can be used to draw on or touch the display panel, leaving a trail. The scanner pen is provided with: an optical reading means that optically reads the dot pattern provided on the display panel; and a dot code analysis means. 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 means 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 means for erasing the displayed trail.
