ていた。The displacement at that time is detected by the horizontal output circuit 104. Conventionally, the sine wave converter 102 was constructed with a resistor 301 and a transformer 302 as shown in FIG. 3, and the voltage was applied to the displacement detector 103 which converted the negative wave into a sine wave. Alternatively, a complex circuit was constructed using transistors and the like to convert the square wave into a sine wave and apply it to the displacement detector. Therefore, the structure 5y of the sine wave converter 102 has a large number of parts, which causes an increase in cost.
