<p>PURPOSE:To reduce the size of the position input device so that the device can be hand-held and operated by calculating a movement quantity from the continuous coordinate output of a touch panel, and further obtaining an output to be moved while the magnifications are varied. CONSTITUTION:The magnifications in an X-axial and a Y-axial direction are set by variable resistors VR1 and VR2 of a magnification setting part 4 in consideration of desired movement width of a cursor on a CRT. Then a coordinate value output part 3 outputs contacted X-Y coordinate data according to movement. Then a coordinate value difference calculation part 5 calculates the differences of the 1st coordinate data of a series of coordinate data from subsequent coordinate data, multiplies the X-coordinate value difference and Y-coordinate value difference by the X-axial and Y-axial magnifications, and outputs the results. This processing is performed by receiving the output of the coordinate value output part 3 at a certain period. Then the output of the coordinate value difference calculation part 5 is outputted through a data transmission part 6 at each time.</p> |
