Abstract
PURPOSE: To enable the display of set value of stylus pressure in agreement with actual stylus pressure, by using the control signal obtained by variable resistor or the like.
CONSTITUTION: The control signal is obtained with the variable resistor 11 for stylus pressure adjustment place at the location ease of operation, e.g., on the front panel, and the signal level can continuously be adjusted. This control signal is converted 12 into digital control signal and the control signal is latched 14 every end of operation of the variable resistor 11. Further, the latch output is decorded 16 and digital display 18 is made as the set value of stylus pressure. Furhter, the latch output is in D/A conversion 15 and it is fed to the stylus pressure adjustment drive circuit 19. The circuit 19 supplies drive current to the stylus pressure application coil 20 depending on the input level. Thus, the display of the set velue of stylus pressure in agreement with the actual stylus pressure can be made.
