Abstract

PURPOSE:To correct the vertical raster shift by providing a pair of permanent mangets at the outside of both side electron beam pass hole sections of an inline type electron gun. CONSTITUTION:An integrated inline type electron gun 7 is arranged in the neck section 4 of a color picture tube 1. Then a pair of permanent magents 211, 212 are provided at the portion facing with the sixth grid 16 of the fifth grid 15 in the electron gun 7 at the outside of the both side electron beam pass hole sections 20R, 20B. Said magnets 211, 212 are magnetized such that the direction of the line of magnetic force formed by said magnets 211, 212 will be in same direction with the arranging directin of the electron beam. Consequently the three electron beams of the vertical raster shift can be corrected uniformly.
