The side pin cushion automatic controller comprises a micom(1) for outputting a digital control signal for controlling a magnitude of a parabolic wave to a D/A converter(2), the D/A converter(2) for converting a digital signal outputted from the micom(1) into an analog signal and outputting given D/C voltage for controlling the magnitude of the parabolic wave to a first amplifier(3), the first amplifier(3) for inversion-amplifying the inputted parabolic wave into the DC voltage outputted from the D/A converter and then outputting it to a clamper(4), the clamper(4) for clamping the maximum voltage of the parabolic wave outputted from the first amplifier(3) to voltage less than given voltage and outputting it to a third amplifier(6), a second amplifier(5) for amplifying the DC voltage for use of a size control of an inputted horizontal screen and outputting it to the third amplifier(6), and the third amplifier(6) for inversion-amplifying the parabolic wave outputted from the clamper(4) and the DC voltage outputted from the second amplifier(5) and outputting the control signal to a side pin cushion outputting unit. |
