Abstract
A reel is provided that may raise the rigidity of the hub, and suppress flange deformation that is caused by winding tension of recording tape. The reel is provided with: a cylindrical hub on which recording tape may be wound; a top flange extending integrally to the hub from a peripheral edge at one end portion of the hub; a bottom flange, including a bottom wall that has had a reel plate fixed thereto, the bottom flange being welded to a portion of the hub at the opposite end of the hub to the end of the top flange, the welding site being within the region where the reel plate is fixed.
Claims12
A reel comprising:
- a cylindrical hub, for winding recording tape thereon;
- a top flange, extending integrally to the hub from a peripheral edge at one end portion of the hub;
- and
- a bottom flange, comprising a bottom wall having a reel plate fixed thereto, the bottom flange being welded at a welding site, to a portion of the hub at the opposite end of the hub to that of the top flange, the welding site being within a region where the reel plate is fixed,
- wherein the reel has a center axis about which the reel is configured to rotate,
- wherein the reel plate has an outer peripheral edge which is provided at a first distance from the center axis in a radial direction of the reel,
- wherein the welding site is provided at a second distance from the center axis in the radial direction of the reel which is smaller than the first distance, and
- wherein the reel plate is insert molded to the bottom wall before the welding of the bottom flange to the hub.
A reel comprising:
- a cylindrical hub, for winding recording tape thereon;
- a top flange, extending integrally to the hub from a peripheral edge at one end portion of the hub;
- a bottom flange, welded at a welding site, to a portion of the hub at the opposite end of the hub to that of the top flange;
- and
- a reel plate, fixed to a bottom wall of the bottom flange that is directly below the welding site of the bottom flange,
- wherein the welding site is positioned within an outer peripheral edge of the reel plate in a radial direction of the reel, and
- wherein the reel plate is insert molded to the bottom wall before the welding of the bottom flange to the hub.
