Abstract

PURPOSE: To manufacture pickup tube units having a low relative pattern distortion by arranging two pairs of flat deflecting coils opposed to each other at right angles around a pickup tube and improving the mechanical precision of the deflecting coils and positional precision with respect to their pickup tube.
CONSTITUTION: Flat coils 10 are used for deflection coils of a pickup tube 1 and two pairs of flat coils 10 are arranged respectively in such a direction that they are at right angles. It is necessary to give a greater winding density to the outer layer part 11 than to the inner one 12 in order to prevent the magnetic field of the peripheral part from being weaker than that of the central part.
