Abstract
Abstract A tape reel apparatus for recording and reproduction of motion picture film or audio tape wherein the tape is pulled off of the supply reel from the innermost convolution thereby obviating the necessity for tape rewinding after use. A pair of spaced reel plates or flanges are joined by a hub and the one plate is provided with means in the form of a ring or a roller on which the rewound tape or film may rotate with respect to the stationary reel plate. The stationary plate has a side release opening for exit of the film or tape from the innermost convolution and a guide device leads the beginning of the film or tape out of the release opening.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
138 words
Apparatus for the handling and storage of recorded tapes or motion picture film on reproducing apparatus without the necessity of rewinding after use, said apparatus comprising a pair of spaced first and second reel plates (1, 2, 9, 10), said first plate being stationary and having a hub (2d, 9d) extending centrally and axially therefrom and being attached centrally and axially to said second reel plate, said second reel plate having winding means (3, 9a) thereon, an exit opening (2c, 10d) in said first reel plate, and means for varying the distance between the reel plates whereby tape or film stored in a wound roll in said apparatus may be pulled through said exit opening when said distance is enlarged, said wound roll then being free to rotate together with said winding means on said second reel plate.
Claim 2
Dependent Claim
138 words
Apparatus for the handling and storage of recorded tapes or motion picture film on reproducing apparatus without the necessity of rewinding after use, said apparatus comprising a pair of spaced first and second reel plates (1, 2, 9, 10), said first plate being stationary and having a hub (2d, 9d) extending centrally and axially therefrom and being attached centrally and axially to said second reel plate, said second reel plate having winding means (3, 9a) thereon, an exit opening (2c, 10d) in said first reel plate, and means for varying the distance between the reel plates whereby tape or film stored in a wound roll in said apparatus may be pulled through said exit opening when said distance is enlarged, said wound roll then being free to rotate together with said winding means on said second reel plate.
Claim 3
Dependent Claim
27 words
Apparatus as defined in claim 1 and further including guide means (2b, 10c) for leading the beginning of the tape or film out of the exit opening.
Claim 4
Dependent Claim
43 words
Apparatus as defined in claim 2 wherein said guide means includes a projection (2b, 10c) spaced from the axis of the reel plates and having a surface (2e) inclined with respect to the reel plate axis for leading out the tape or film.
Claim 5
Dependent Claim
13 words
Apparatus as defined in claim 3 wherein said projection is curved and wedge-shaped.
Claim 6
Dependent Claim
26 words
Apparatus as defined in claim 1 wherein the winding means comprises an annular roller (3) mounted on a ring section (1d) of said second plate (1).
Claim 7
Dependent Claim
60 words
Apparatus as defined in claim 5 wherein said means for varying the reel plate distance includes a plurality of notches (3a) on said roller having a trapezoidal cross section, said second reel plate (1) being provided with cam means (1b) which grip in said notches so that when said roller rotates, a relative axial displacement occurs between said reel plates.
Claim 8
Dependent Claim
46 words
Apparatus as defined in claim 6 wherein said hub (2d) is provided with an axial groove (2f) and said ring section (1d) is provided with a lug (1a) fitting in said axial groove so that a coupling is provided during rotation and limits the axial displacement.
Claim 9
Dependent Claim
24 words
Apparatus as defined in claim 1 wherein the winding device consists of a ring (9a) which is secured tightly on said second plate (9).
Claim 10
Dependent Claim
47 words
Apparatus as defined in claim 8 wherein said second plate (9) is provided with said hub (9d) and the first plate (10) is equipped with a ring section (10g), and a clamping cap (11) is adapted to be clamped on said hub and holds the first plate.
Claim 11
Dependent Claim
34 words
Apparatus as defined in claim 9 wherein said cap (11) is provided with a flanged projection (11a) and said ring section is provided with a notch, thus limiting the axial separation of the plates.
Claim 12
Dependent Claim
18 words
Apparatus as defined in claim 1 wherein the first reel plate is provided with gripping notches (10d, 10f).
Claim 13
Dependent Claim
52 words
Apparatus as defined in claim 1 and further including a mounting adapter for positioning said reel plates for winding, said adapter including a carrier 4 having a plurality of axial notches (4a) for attachment onto reproduction equipment and a reel pin (6) mounted on said carrier for attachment of said reel plates.
