ABSTRACT:
A rotary card file in which a card holder supported for rotation by a base structure has a plurality of trays that extend from a central hub and are equipped with retainer tracks that keep the cards in file alignment when the card holder is turned to position the tray in an upwardly facing access position, and which support the cards suspended from the tray when the card holder is turned to position the tray in a downwardly facing storage position [.] ; and which in one embodiment of the invention, that shown in FIG. 9, has means for removably holding the trays against radially outward movement from the rotary card holder during traverse of the trays along the lower part of their circular orbit.
