Abstract
A cylindrical reel-hub for a tape, in particular a magnetic-tape or ink ribbon, is divided in into two semicylindrical reel-hub portions along a dividing zone. The reel-hub portions are integrally interconnected by an elastically deformable bridge which bounds the dividing zone at one end and which constitutes a hinge between the two reel-hub portions. The reel-hub portions are held together by a connecting means at the open end of the dividing zone to clamp a tape introduced into the clamping zone between them. The two ends of the dividing zone are substantially diametrically opposite one another and the dividing zone extends in a substantially radial direction at its open end.
Claims18
In a reel hub for a tape having an annular hub with an outer circumferential surface for winding a tape thereon and an inner portion defining an opening and having an arrangement of driving elements, said annular hub defining a hub axis transverse to the plane of the hub and having two hub portions separated along a substantially radial direction at a first circumferential hub location and, at a second circumferential hub location substantially diametrically opposite said first circumferential location, said hub being partially separated in a direction extending from said inner portion towards said outer circumferential surface forming an elastically deformable bridge connecting said two hub portions, at said first circumferential location said hub portions having opposing faces comprising tape clamping means for clamping an end portion of a tape therebetween and locking means for locking said two hub portions together in a direction transverse to said hub axis, wherein the improvement comprises:
- said hub at the area of said first circumferential location comprising axial aligning means for axially aligning said two hub portions.
In a tape cassette having a housing and two annular reel hubs disposed therein, each hub defining a hub axis transverse to the plane of the hub and having an outer circumferential surface for winding a tape thereon and an inner portion defining an opening with an arrangement of driving elements, and said housing having a pair opposing major walls and narrow side walls extending between said major walls, said major walls having inner annular flanges for rotatably supporting said reel hubs and openings coaxial with said annular flanges for allowing insertion of winding spindles for engaging with said driving elements of said reel hubs, wherein the improvement comprises:
- a said hub having two hub portions separated along a substantially radial direction at a first circumferential hub location and, at a second circumferential hub location substantially diametrically opposite said first circumferential location, said hub being partially separated in a direction extending from said inner portion towards said outer circumferential surface forming an elastically deformable bridge connecting said two hub portions, at said first circumferential locatin said hub portions having opposing faces comprising tape clamping means for clamping an end portion of a tape therebetween, and locking means for locking said two hub portions together in a direction transverse to said hub axis, and
- said hub at the area of said first circumferential location comprising axial aligning means for axially aligning said two hub portions.
