Abstract

PURPOSE:To perform simple and accurate adjustment of alignment by providing single permanent magnet movably in axial and circumferential directions then adding an adjusting terminal to it thereby making the strength of magnetic field easily variable. CONSTITUTION:Extended sections 3a, 5a are provided on an assembly having a bobbin 3, deflection coil 4 and a magnetic shield 5 to form a circular groove 6, then single permanent magnet 2 is arranged movably in axial direction and rotatably in said circular groove 6. In order to adjust the alignment an adjusting terminal 7 is projected from the permanent magnet 2 toward the rear end of image pick-up tube 1. When moving the adjusting terminal in axial direction and rotating, the alignment is adjusted easily.
