Deflection yoke assembly positioning device

A device for positioning a deflection yoke assembly on a cathode-ray tube comprising:

• (a) first oscillating means comprising grasping means including a plurality of rollers for rotatably grasping the deflection yoke assembly in such a relation that the center of the fixing portion of the deflection yoke assembly is located on a horizontal axis, and causing controlled vertical oscillating movement of the opening portion of the deflection yoke assembly around said center of said fixing portion;
• (b) rotating means associated with said first oscillating means for causing controlled rotating movement of the deflection yoke assembly grasped by said first oscillating means around the axis of the deflection yoke assembly;
• (c) second oscillating means for supporting said first oscillating means in such a relation that said center of the fixing portion of the deflection yoke assembly grasped by said first oscillating means is located on a vertical axis, and turning said first oscillating means around said vertical axis thereby causing controlled horizontal oscillating movement of the opening portion of the deflection yoke assembly around said center of said fixing portion;
• and
• (d) sliding means carrying said second oscillating means thereon for causing controlled sliding movement of said second oscillating means in the axial direction of the neck portion of the cathode-ray tube thereby causing controlled sliding movement of the deflection yoke assembly grasped by said first oscillating means in the axial direction of the neck portion of the cathode-ray tube.
