1. A handwritten character input device comprising:
- a dot-matrix display panel having dot coordinates;
input means for generating magnetic fluxa tablet having detection coordinates corresponding to the dot coordinates of said display panel, said tablet being positioned next to said display panel and being responsive to magnetic flux from said input means; and
coordinate conversion means for selectively permitting manual adjustment of said dot coordinates by a desired amount such that said dot coordinates are shifted vertically and laterally with respect to their corresponding detection coordinates;
said dot coordinates on said dot-matrix display panel being selectively shifted to compensate for certain characteristics of a user of said handwritten character input device, said certain characteristics being at least parallax due to an altitude or posture of the user and a deviation in detecting said magnetic flux due to the tilt of the input means.

Abstract
A handwritten character input device in which a dot-matrix display panel and a tablet are laid one on the other. The detection coordinates of the tablet correspond with the dot coordinates of the display panel. A coordinate conversion unit is provided for shifting the dot coordinates vertically and laterally with respect to the detection coordinates of the tablet.
