ABSTRACT:
A deflection apparatus for cathode ray tube is provided, which comprises deflection yoke with guide grooves, deflection windings for scanning in one direction in said grooves, deflection windings for scanning in the other direction and an insulator between both types of windings. It attains high accuracy deflection with less distortion without any induced heating problem due to protuberances made relatively between grooves.
