Abstract
A four position interlacing apparatus includes an interlace mirror of electromagnetic material, and an interlace mirror support member of magnetic material having a faceted surface for supporting the interlace mirror. The supporting surface has a centrally disposed ridge from which a pair of downwardly sloping facets extend at first preselected interlace angles to form ridges with a pair of downwardly sloping facets extending therefrom at second preselected interlace angles, and a corresponding plurality of bars of non-magnetic material for dividing each facet between the ridges to form a plurality of magnetic core members. Each bar of non-magnetic material extending vertically downward to aperture forming walls of the support member, said support member having solid reel bars formed in the apertures with a plurality of coils surrounding the reel bars. A control circuit selectively energizes the coils first in one direction to magnetize the cores in a preselected order to draw the interlace mirror to the energized facet and in an opposite direction to assist in the movement of the interlace mirror to the next selected facet.
