ABSTRACT:
An apparatus as disclosed that receives, vertically stacks and directionally collates computer diskettes. The apparatus stacks the diskettes in the actual order in which they are received, with the first diskette received at the top of the stack and the most recently-received diskette at the bottom of the stack. A tray attached to a drive nut receives diskettes in a lowered position and, if appropriate, swivels the tray 90 degrees before raising the diskette into a bin opening located at the bottom of a vertical stacking bin. Retractable wedge-shaped finger members support the diskette stacked in the bin and retract as a diskette is raised. The tray and drive nut are raised and swiveled by way of a rotating shaft extending in the bore of the drive nut. The shaft has a double helical groove on its surface which is engaged by a pawl swivelably attached to the drive nut.
