Abstract
There is provided a sine wave deflecting circuit having a resonance circuit comprising a deflecting coil and a resonance capacitor and a circuit for detecting a signal waveform of the resonance circuit and for driving the resonance circuit on the basis of the detection signal, in which the deflecting coil is sine-wave driven by the self-oscillation. A rectangular wave driving circuit which is constructed by connecting first and second switching elements such as FETs through a capacitor is provided at one end of the deflecting coil.
