Abstract
A selectively operable interposer mechanism for positioning bars, or the like, in a card selector or coder. Each interposer includes an interposer blade of magnetically responsive material disposed in a longitudinal slot of a nonmagnetic platen. A bar is disposed in each slot and is adapted to be pushed by the interposer blade acting through a rolling disc disposed in the slot between the blade and bar. Disposed directly above each interposer blade is a solenoid coil effective, when engaged, to pivot the associated interposer blade into contact with a permanent magnet which captures the interposer blade. A pusher assembly including the permanent magnet is operative to displace each captured interposer blade and the associated bar longitudinally along their respective slots from a rest position to a displaced position. After a coding or sorting operation, the pusher assembly returns the bars and interposers to their initial rest position. In this position, the magnet is disengaged from the interposer blades; and since the solenoids are disengaged, the blades drop to their unactuated position within the slots.
