Abstract: An adjustable reel or a spool has a pair of flanges connected by a shaft or barrel wherein each flange has a plurality of extensions arranged circumferentially and directed toward the opposite flange. Each flange has a plurality of openings spaced to match the extensions from the opposite flange which may enter thereinto. The extensions are spaced to be interleaved. In the preferred form, the extensions are spaced transversely, preferably 60.degree. and also extend 60.degree.. The two flanges, when placed with the extensions interleaved, form a single reel with a secure connecting shaft or barrel between them providing a solid support for material to be wound thereon. The spacing of the spool between flanges is infinitely adjustable. Preferably, each flange and its extensions are made from a mold of the same type so that the opposite flanges are mirror images of each other and may readily be placed together.

Abstract: A tape winding device for a magnetic tape in which an annular magnet surrounds a drive shaft of a take-up reel. The magnet is supported on a side opposite the reel by a ferromagnetic support.

Abstract: In a magnetic tape winding system, an end portion of a magnetic tape, which is cut after the magnetic tape is wound by a predetermined length from a magnetic tape feed roll to a first small wind-up frame, is joined with one end portion of a leader tape having the other end portion engaged with a second small wind-up frame by use of a joining tape. Immediately after the joining, the magnetic tape and the leader tape joined by the joining tape is rewound by a predetermined length around the second small wind-up frame, whereby slack of the tape between the first small wind-up frame and the second small wind-up frame is eliminated without causing the joining section of the magnetic tape with the leader tape to contact the magnetic tape surface at the outermost circumference of the magnetic tape roll wound around the first small wind-up frame.

Abstract: In a film cassette, a convoluted film roll is wound on a spool between a pair of coaxially spaced flanges of the spool. A plurality of rigid constraining projections fixed to the respective undersides of the flanges radially confine the outermost convolution of a widened film leader to prevent the film roll from radially expanding into contact with the cassette shell. The constraining projections are each arranged in a slipping relation with the outermost convolution of the widened leader to allow the outermost convolution to readily slide in contact with the constraining projections in order to facilitate a limited degree of radial expansion of the film roll. When the spool is rotated in an unwinding direction, the film roll will tend to expand radially since the inner end of the filmstrip is attached to the spool, and the spool will rotate the film roll in the unwinding direction.

Abstract: A disc player, for playing various information carrier discs, which includes, a single turntable for supporting an information carrier disc, a single drive motor for rotating the turntable, and a reproducing head device for reading signals recorded on the disc. The drive motor has a motor body and a rotation shaft, and is attached at its rotation shaft directly to the turntable with its motor body spaced apart from the turntable. Therefore, a clearance is formed between the motor body and the turntable. The reproducing head device is radially transferrable relative to the turntable. When the reproducing head device is transferred to its innermost position where it reads the signals recorded on the inner periphery of the information area of the disc, it is positioned in the clearance without butting against either the motor body or the turntable.

Abstract: A spool for holding photographic film, consisting of a core member provided with flanges between which flexible film may be wound and an elongated slot into which the end portion of a film strip may be entered and fastened. Adjacent the flanges are raised shoulders extending about the circumference of the core and above the core surface. The shoulders each gradually increase in thickness in the film-winding direction and terminate in a stepped portion corresponding to the thickness of the film. In a preferred embodiment, shoulder portions accommodate the edge portion of a full-width film, have an initial height above the surface level of said spool, and then rise gradually to an additional height approximately equal to the thickness of the film. When the full-width portion of the film is juxtaposed the spool flanges, said shoulders provide the film with a substantially level transition surface for each convolution of the full-width film, thereby avoiding imperfections on the spool-core surface.
