ABSTRACT:
A signal processor for a joystick which includes a joystick input device (11) which varies a joystick voltage input value Vi according to an operating amount of a joystick (10) from a neutral position (11), an input circuit (13) which outputs the average value of the joystick voltage input value Vi read at every sampling time over a predetermined number of past occasions as a joystick voltage computation value Vic, a computation circuit (14) which computes an output computation value Voc set according to the joystick voltage computation value Vic, and operation start detecting circuit which detects an operation start when the joystick (10) is pushed over from the neutral position. The computation circuit (14) increases the output computation value Voc to an effective maximum value when operation starts. In this way, over-sensitivity of the control response when there is a sudden operation of the joystick (10) is suppressed.
