ABSTRACT:
A joystick control device having cursor correcting function, in which the conventional adjustable resistor is replaced by a photoelectric element for detecting the movement of the joystick, thereby eliminates the ill effects caused by mechanical attrition of resistor. Additionally, the parameter drifts caused by IC manufacturing processes are corrected using shift correction of joystick; therefore, every individual mass-produced IC shows similar good behavior.
