A data input system is provided with an input pen. A sequence of characters are traced with the input pen, and image data on them are read from the image scanner incorporated in the input pen. Each character is recognized on the basis of the image data. If a recognition error occurs during the input processing, a correct character is written with the input pen. A locus of movement is traced on the basis of moving distance data, which is obtained by a moving distance sensor and includes a moving distance and a moving direction. A character represented by the traced locus is recognized.
