<p>A character reader includes a digitizer having a tablet on which characters are manually written with a stylus pen. The digitizer outputs position data on a contact position of the stylus pen with the tablet when the character is written on the tablet. A non-contact period during which the stylus pen is detached from the tablet is counted in response to the position data supplied thereto from the digitizer. The non-contact period thus obtained is compared with an identification period and a one character input completion signal is generated when the non-contact period is longer than the identification period. Movement loci of the stylus pen are obtained based on the position data. The character is recognized based on the movement loci and the one character input completion signal. An identification period compensator compensates the identification period so that the identification period is lengthened or shortened as the non-contact period shorter than the identification period among those between the time of detachment of the stylus pen and the time of the subsequent contact is lengthened or shortened respectively after the stylus pen is detached from the tablet and then brought into contact with the tablet again.</p> |
