<p>PURPOSE:To measure an accurate coordinate value by registering a coordinate compensation value corresponding to the peak value of an induced voltage in a storage device, detecting the peak value of the induced voltage, calling the coordinate compensation value corresponding to the peak value based on it and compensating the count value of a pulse counter by means of the coordinate compensation value. CONSTITUTION:The induced voltage is generated in the coil 6 of a cursor 4 by a signal from a tablet 2 side. The timing of a stop pulse for stopping the pulse counting operation of the pulse counter is set by the induced voltage. At that time, the coordinate compensation value corresponding to peak value of the induced voltage is registered in the storage device, and the peak value of the induced voltage is detected. Then, the coordinate compensation value corresponding to the peak value based on it is called and the counting value of the pulse counter is compensated by the coordinate compensation value.</p> |
