<p>PURPOSE:To exclude the correcting operation of minute deviation generated at the time of input operation where a mouse is manually moved in X-axis and Y-axis directions on a horizontal plane. CONSTITUTION:An inhibit switch 11 inhibits an X axis pulse. An inhibit switch 12 inhibits a Y axis pulse. An X axis grating detector 14 and a Y axis grating detector 15 detect the grating from a photosensor 13. An output control circuit 16 controls inhibition of output of X axis and Y axis pulses outputted from inhibit switches 11 and 12.</p> |
