Abstract
A data entry and writing device is equipped with an optical detector comprising light emitting elements and light receiving elements disposed around an opening formed in the device, a character/graphic analyzer for analyzing the locus of a pen which is moved within the opening using time-series coordinate data to thereby perform character/graphic recognition and a display unit for displaying data entered through the character recognition. The data entry and writing device is placed on a form and data are handwritten on the form with the pen through the opening. This permits automatic data entry into the device and data is also displayed on the display unit. The device also includes an erroneous preventing circuit which automatically indicates where errors exist between the data entered by the pen and data processed by the device and guides a user to correct the errors.
