ABSTRACT:
Apparatus for accurately positioning a panel, which has been brought to a position near to its correct position, by using, as a reference, panel pins projecting from inner lateral surfaces of the panel in a process for manufacturing color picture tubes. The apparatus includes substantially horizontal support means for movably supporting the panel thereon, and a plurality of positioning units each having a positioning lever formed therein with a guide groove adapted to engage one of the panel pins of the panel placed on the support means for positioning the panel in a predetermined position on the support means. The apparatus also includes a panel holding device effective to hold the panel pins of the panel positioned in the predetermined position on the support means so as to move the panel upwardly to a predetermined height, thereby effecting positioning of the panel in a vertical direction.
Combined with a mask holder for holding a shadowmask and moving the same upwardly to a predetermined position, the positioning apparatus is capable of functioning as apparatus for mounting the shadowmask in the panel.
