Claims

[Scope of utility model registration request]

(1) In a deflection yoke housed in a shield case and disposed outside the image pickup tube, a pair of annular alignment magnets having a gear portion along the outer periphery, and a gear portion of each of the pair of alignment magnets are provided. A deflection yoke is provided with a pair of meshing gears, and is configured such that rotation of each gear rotationally displaces each alignment magnet so that an electron beam focusing magnetic field of an image pickup tube is aligned orthogonal to a photoelectric conversion surface. .

(2) The deflection yoke according to claim 1, wherein the shield case has an opening in a portion corresponding to the pair of gears.
