<p>A vertical deflecting circuit comprises a vertical output circuit (12) which amplifies an input sawtooth wave signal and supplies a deflection current to a vertical deflection coil (13), a power source (14) which applies a source voltage to the vertical output circuit, a first pump-up circuit (17) which raises the voltage from the power source, and a second pump-up circuit (18) which further raises the output voltage from the first pump-up circuit. In a fly-back time of a vertical output signal, the vertical output circuit is operated by the voltage from the second pump-up circuit, and the vertical output circuit is operated by the voltage from the power source during a time coefficient. <IMAGE></p> |
