<p>PURPOSE:To provide a coordinates detective apparatus with high detective accuracy which judges whether the direction of an operation body accords with a moving target or not by comparing the coordinates data of the operation body and the planar coordinates of the moving target on the display. CONSTITUTION:When a switch signal is generated by operating a trigger 7 of the operation body, e.g. a pistol 5, CPU 10 drives the driver 11 and causes LED 4 to start. Thereupon, a spotlight S is irradiated on the light sensor 6 from LED 4 and the fractionated light receiving section of the light sensor 6 outputs the electric current value in proportion to the irradiated area by the spotlight S. The frequency element in the pulse light emission of the outputted electric current is exclusively taken up at the filter.ANP section 12 and, after being amplified at ANP 13, inputted to the A/D converter 14. The detection electric current, converted further to a digital value, is sent out to CPU 10. Then CPU 10 executes the specified arithmetic processing and judges whether the direction of the pistol 5 accords with the moving target or not.</p> |
