Claims

[Scope of utility model registration request]

a core; a pair of saddle-shaped horizontal deflection coils and a toroidal or saddle-shaped vertical deflection coil wound along the inner surface of the core; and the horizontal deflection coil and the vertical deflection coil arranged on the inner surface of the core. In a picture tube device in which a deflection yoke is constructed of a coil bobbin that maintains insulation between the coils and defines the position of each coil, and the deflection yoke is mounted on the neck of the picture tube, the external part of the deflection yoke is a magnetic piece located on at least one side of the X-axis direction of the deflection yoke and covering the outside of the core forming a part of the deflection yoke; and a magnetic piece wound in a toroidal shape along the tube axis direction on the outer periphery of the magnetic piece. An unnecessary radiation countermeasure means consisting of a rotated coil is installed via a separate non-magnetic support member independent of the deflection yoke, and the unnecessary radiation countermeasure means is connected to the horizontal deflection coil of the deflection yoke. A picture tube device characterized in that a magnetic field opposite to the magnetic field leaking to the outside of the core among the generated horizontal deflection magnetic fields is generated.
