Abstract

PURPOSE:To make small the scanning set and to simplify the operation, by enabling low and high speed (TV) scanning with the same deflection circuit. CONSTITUTION:In the high speed scanning, the switch S1 is selected to b1 for the zero output terminal a2, s2, and the rectangular signal having blanking time is inputted from b1 and the operational amplifier 11 is fully saturated. The transistor Tr15 switches the positive and negative value of the DC power supply voltages E11 and E12, and the collector current of the saw tooth wave c is carried to Tr 17. During the blanking period, all the transistors are turned off, the inductance L12 and the capacitance C12 of the deflection coil 12 are in resonance and since the current i10 of the waveform e is carried, i12 of the waveform d is continuously carried to the resistor R12 and L12 of the coil. In low speed scanning, saw tooth current is inputted by selecting S1 to a1 and S2 and S3 are connected to the zero output terminal. When the saw tooth voltage is inputted to the positive terminal of the amplifier 11 via R11, the current of the same shape is carried to L12 and R22, R22 detects the voltages and amplifies 13 it, making the difference between the detection voltage of R22 and the input voltage of R11 to zero.
