Title:
YOKE ASSEMBLY FOR IMAGE PICK-UP TUBE
Document Type and Number:
Japanese Patent JPS5725658
Kind Code:
A
Abstract:

PURPOSE: To eliminate the misregistration by providing levers for adjusting the position of a coil on the horizontal/vertical deflection coil and the alignment coil of an image pick-up coil.

CONSTITUTION: Horizontal and vertical deflection coils 4, 5 are wound around a tubular coil bobbin 3 while said bobbin 3 is penetrated through said coils 4, 5 then nonmagnetic position adjusting levers 12, 13 are fixed. Said levers 12, 13 are constructed such that the fixing position of the deflection yoke is movable in axial and rotary direction. While a lever 14 where the fixing position is movable only in axial direction is fixed on an alignment coil 7. Then one ends of the levers 12, 13 and 14 are projected to the outside to enable the moving operation from the outside. Consequently the misregistration caused by the assembling accuracy of the yoke and the manufacturing accuracy of the image pick-up tube can be eliminated.
