路。 A deflection current control power supply circuit that supplies horizontal deflection current to the horizontal deflection coil varies the output voltage based on the peak value of the retrace pulse, controls the horizontal amplitude to a constant value, and controls the horizontal deflection current connected to the horizontal deflection coil. A multi-scan horizontal polarization circuit that switches a capacitor capacity of an S-shaped correction circuit for correcting a waveform into an S-shape according to a horizontal deflection frequency, the capacitor capacity being connected between the S-shaped correction circuit and the deflection current control power supply circuit. A multi-scan horizontal deflection circuit is provided with a damper circuit that attenuates unnecessary low-frequency resonance waves that are parasitic to the horizontal deflection current as the horizontal deflection current is switched.
