体的な計算式は、以下を適用する。First, touch panel data based on the pen locus of the touch panel is sampled, taken into the data control unit 2, and converted into display coordinate data on the display unit 4. The converted display coordinate data is taken into the FIFO memory 5 in the error removing section 3. The FIFO memory 5 always holds 10 pieces of display coordinate data in the order of input. When the pen presses the touch panel and moves (when the pressing information is information that the pen is always pressed even when the pen is moving), 10 pieces of touch panel data are acquired when the start point is pressed, and 10 pieces of data are stored in the FIFO memory 5. Display coordinate data for each piece is held. Then, an average value of 10 pieces of display coordinate data held in the FIFO memory 5 is calculated, and the average value is held in the error-removed data storage memory 6. The display coordinate data of the average value is passed to the display unit 4 and displayed as dots at the coordinates of the display unit 4. Regarding touch panel data generated after the start point of pressing, the display memory 10 discards the oldest display coordinate data by sequentially holding 10 pieces of display coordinate data in the FIFO memory 5 for each sampling. The following is applied as a specific calculation formula for obtaining the average value of the display coordinate data in the error removal data storage memory 6.
