Abstract
To provide for conjoint movement of reel tables (1,2) on which the centers of winding reels of cassettes having different reel spacing, for example from a set of cassettes, can be positioned, the reel tables are located on respective carriages (5,25) operable in a common plane along guide reels or rods (3,4; 23,24), and commonly driven from a single motor (13). The motor 13 is in engagement, via bevel gears coupled to the shaft, with two spindles (7,27), engaged by spindle nuts which are coupled to the respective carriages, so that, upon rotation of the motor, both of the reel tables will move in a common plane and will shift proportionately along the guide tracks or rods, thereby moving conjointly, and proportionately with respect to said axis of symmetry.
Claims3
Magnetic tape winding apparatus for combination with any one of a set of magnetic tape cassettes
- in which the winding centers of tapes within the cassettes of the sets differ from each other,
- said apparatus having two reel tables (1, 2) located in a common plane;
- the centers of the reel tables being movable in a plane parallel to said common plane;
- and
- wherein said reel tables are movable in converging angled paths symmetrical with respect to an axis of symmetry (X--X) between the angled converging paths;
- and
- motor drive means (13) are provided to position the reel tables (1, 2) in accordance with the position of the winding centers of a specific cassette of the set,
- comprising, in accordance with the invention,
- coupling means (7, 10, 11, 12, 27, 30) coupling the drive means to both of said reel tables for moving the reel tables in said common plane, said coupling means being characterized by comprising coupling elements displaceable respectively in linear paths extending in the same directions as said converging angled paths by a distance which, with respect to rotation of said drive means has a linear distance vs. angle-of-rotation relationship.
