Abstract
A character recognition device has an input section having a plurality of touch electrodes. When the human body contacts at least two of the touch electrodes of the plurality of touch electrodes, the contacting capacity components of the touch electrodes are detected by a capacity component detection section. The contacting central point coordinates of the touch electrodes are calculated by calculation sections from the contacting capacity components of the touch electrode thus detected. The character hand-written on the plurality of touch electrodes is recognized as a character by character recognition sections, from the contacting central point coordinates calculated by the calculating sections.
