Abstract
PURPOSE: To avoid the misdisplay of stylus pressure, by the constitution that the display of stylus pressure is made when it is a given value or more.
CONSTITUTION: The Hall voltage output from the Hall element 1 is changed by changing the magnetic field fed to the Hall element 1 according to the stylus pressure to measure the stylus pressure. The display and indication circuit 42 enabling the display of stylus pressure when the stylus pressure is more than the specified value, is constituted with comparators. The analog voltage corresponding to the minimum display stylus pressure 0.5g is input to the noninverting input of the comparator 42, and the output voltage of the zero point correction circuit 20 is input to the inverting input side, then the output of the comparator 42 is inverted when the stylus pressure is 0.5g or more. This inversion output is the display and indication output.
