PURPOSE:To decrease the loss of an output transistor and a deflection coil even when a horizontal deflection frequency is high. CONSTITUTION:The output pulse of an oscillating circuit 3 is (1/2)-divided by a divider 7, the width of the pulse is adjusted by a width adjusting circuit 8, and a sawtooth deflection current at the frequency (1/2)-divided through a first driving circuit 4a and a first output circuit 5a to a first deflection coil 13a is made to flow. On the other hand, at the rear step of the divider 7, a delaying circuit 9, a second driving circuit 4b and a second output circuit 5b are provided, and the deflection current in which the current to flow at the first deflection coil 13a at a second deflection coil 13b and the phase are dislocated only by pi[rad] is made to flow. |
