<p>PURPOSE:To make a focus variable resistor section small in size by providing two rotary shafts to a same center shaft. CONSTITUTION:A resistor 14 for dynamic focus is arranged to the right side and a resistor 17 for static focus is arranged to the left side on a same ceramic board 12. A rotary shaft and a rotating member are formed to be rotated around a same center axis and each focus resistor and conductors 15, 18 for extracting the inner voltage are conducted by using the rotary shaft and a metallic brush provided to the rotary member, the contact position between the resistor 14 and the brush is moved by turning the shaft and the contact position between the static focus resistor 17 and the brush is moved by turning the rotary member.</p> |
