Abstract

PURPOSE:To facilitate adjustment by using the first magnetic means that affects only one outer electron beam and the second magnetic means that affects only the other outer electron beam. CONSTITUTION:The first and second magnetic means 19 and 20 permit the neck section of a cathode-ray tube to penetrate and to shift in the normal direction to the neck section axis. They are also formed in an elliptic shape with long holes 39 and 40 so as to be able to rotate around the neck section 2 and mounted on the cylindrical section 4 of a holder 3. The magnetic field by the first magnetic means 19 substantially effects on only one outer electron beam and the magnetic field by the second magnetic means 20 substantially effects on only the other beam.
