<p>PURPOSE:To provide a data input device capable of preventing operating environment from worsening due to the change of an angle of parallax. CONSTITUTION:When the power source 15 of the data input device is applied, correction data TABX, TABY in the X and Y axial directions are inputted to correct 16 an error, and the input positions of the data can be corrected based on such error correction. When it is judged that corrected coordinates are outside an ordinary recognition range 13 but within a correction recognition range 14 slightly wider than that (YES in step #23, NO in #29, #31), the variables TABX, TABY are updated based on distance between the input position and the ordinary recognition range 13.</p> |
