A filing unit for storage and retrieval of magnetic recording disks is disclosed. The unit includes a plurality of pockets or storage panels which can be removably stored in a modular holder and the holder itself can be combined with various other filing components, such as a storage binder having front and rear covers or a desk-top filing stand. In the preferred embodiment, the pocket is carried by a file bar affixed along one edge thereof. The holder includes a plurality of parallel channels each adapted to pivotally receive the file bar of a storage panel. Each channel includes retaining lugs which straddle the channel and are flexible to permit snap-insertion and removal of the bar from the holder.

Storage file for magnetic recording disks

Loose leaf binder composed of an arcuate back panel, pivotable cover panels and a toggle ring mechanism which is affixed to the inner concave surface of the back panel. The toggle mechanism includes spaced leaf ring members each composed of a pair of mating sections pivotable with the toggle mechanism between open and closed positions. Each ring member is defined by rectilinear leg portions extending outwardly of the toggle mechanism, upwardly and inwardly extending arm portions and transversely extending arcuate rail portions supported by the arm portions of the ring in spaced relation to the arcuate back panel. Each of the arm portions has a unidirectional slope and with a corner of generous radius fairs together with each rail portion, enabling the loose leaf sheets held on the rings to be smoothly swung from one side to the other of the binder.

Loose leaf binder

A holder for the storage, handling, and filing of sound recording magnetic tape cassettes which is an integral tray-shaped frame, includes a support beam disposed along its upper edge and an index bar extends upwardly of the beam and serves as a handle for the holder. A rectangular base or back panel depends from the lower edge of the support beam and side walls extend outwardly of the marginal edges of the base panel. Spaced posts extend upwardly of the base panel and are adapted to engage and prevent rotation of the reels of said cassette. A resilient retaining flange or tab extends from one of the side walls in spaced parallel relationship to the base panel for releasably gripping a cassette. The base panel is provided with an aperture disposed opposite the retainer tab to accommodate therein a raised land portion of the tape cassette.

Tape cassette holder

A card filing device for storing and viewing card carrying envelopes wherein slotted card carrying envelopes are pivotally mounted in the device so that they are movable from a horizontal storage position to a vertical viewing position and only removable from said container by pivoting the same to a position approximately midway between said storage and viewing positions.

Mag card storage device

A binder for filing microfiche cards together with a portable card viewer, said binder having a pair of hinged cover panels connected by a U-shaped assembly and a looseleaf binding mechanism mounted between the sides of said assembly above the back panel thereof thereby forming a compartment between said binding mechanism and said back panel. Said back panel being provided with an opening for receiving the barrel of the card viewer when said viewer is held against said back panel of said assembly by a releasable retainer flap.
