    • In a horizontal deflection output circuit adapted for correction of horizontal linearity in a television receiver or the like, and which comprises a switching transistor, a damper diode, a horizontal deflecting coil and an S correcting capacitor connected in series to the horizontal deflecting coil; the terminal voltage of the S correcting capacitor is modulated by a sawtooth signal produced by a linear distortion correcting circuit synchronously with a horizontal periodic signal. The sawtooth signal produced by the switching transistor and fed to the horizontal deflecting coil is applied to the S correcting capacitor which feeds an S correcting current to the horizontal deflecting coil, so as to correct the image distortion caused particularly by the resistance component of the horizontal deflecting coil.

    • In a dual direction horizontal bi-directional scan circuit, deterioration of the picture quality is prevented, while linearity is improved without supplying wasteful deflecting current, and pin distortion is corrected. The deflecting current in the going scan and in the returning scan are supplied to each deflecting coil by first and second resonance circuits, and capacitors substantially the same in capacitance are provided in the first and second resonance circuits to bias the deflecting voltage so that the terminal voltage and the power source voltage of the capacitors are synchronized to the vertical synchronizing signals to produce a parabolic modulation.
