As a result, a voltage waveform of an output of the IC 2 is changed vertically in response to the control of the DAC to move vertically a raster range of a display screen. A voltage wave is applied to the IC 2 to supply a required sawtooth wave deflection current I from an output terminal C of the IC 2 to a vertical deflection coil DY connecting to the next stage of the IC 2. Thus, the dispersion in the circuit 3 is corrected by adjusting the reference voltage.
