Abstract
PURPOSE:To always ensure the correct working of a cursor by using a gate means which prevents the output of a set signal when the neutral point of a lever is detected and therefore the error of said neutral point is automatically corrected. CONSTITUTION:The pulse width of the signal delivered from a time constant circuit 11 and corresponds to the position of a lever 24 of a joy stick is corrected to the value corresponding to the neutral point of the lever 24 in case a signal UP or DOWN is delivered from a comparator 14 even though a photocoupler 16 detects that the lever 24 is set at its neutral point. Thus it is possible to eliminate an inconvenient case where a cursor moves although the lever 24 is kept at its neutral point. As a result, the readjustment jobs of the joy stick due to the secular change can be extremely decreased. Furthermore the cursor never moves on a screen while the lever 24 kept at its neutral point since a gate circuit 15 is closed.
