Abstract
PURPOSE:To improve the resolution of position detection by providing a gate circuit by providing a gate circuit which samples the detection signal of a detecting circuit by the sampling pulses of a width smaller than the time intervals of scanning between luminescence spots. CONSTITUTION:In the apparatus of detecting the luminescence spots of, e.g., a braun tube, and obtaining the signal of its detection position, a gate circuit 3 is provided between a detecting circuit 1 and the terminal 8 of the output circuit of the detecting signal and the sampling pulses coinciding with the point to be detected and of a pulse width smaller than the time intervals of scanning between the detection points are applied to this gate circuit 3. The detection signals are sampled by these sampling pulses. For example, the photo detecting signal having been inputted to the gate circuit 3 is outputted as the position detecting signal from the output terminals 8 only when the vertical and horizontal pulse signals PV, PH are applied, and therefore even if the detection range I overlaps the adjoining luminescence points A, the outputs of both positions cannot be obtained unless it is across the detecting regions encircled by the broken lines of a width l.
