Abstract
A cassette for blood smear slides has a holder portion for supporting slides in a stack and an alignment surface for orienting a bottom slide with respect to a slide egress window. A force plate member is urged against the top slide in the stack with a constant force spring to align the bottom slide and to retain the slide stack. A slide extraction device is constructed to enter the cassette and has follower pins which ride on cam surfaces of the cassette to precisely position detent edges vis a vis an edge of a bottom slide of the stack. The cassette also has structure for signaling an empty condition.
