<p>A tape cartridge includes a single tape reel (3) around which a length of magnetic tape is wound and which is turnably held within a housing. The beginning of the tape us fixed to a leader (9) so that it can be drawn out through an opening formed in the housing by a tape drawing-out member of a recorder which has an end capable of engaging the tape end. The leader comprises a center pin member (91) on which the beginning of the tape is wound and a pair of engaging members (92-1, 92-2), of synthetic resin joined to the upper and lower ends of the pin member (91) so as to engage the tape drawing-out member of the recorder. The center pin (91) and engaging members (92-1, 92-2) are molded in one piece. The center pin (91) and engaging members (92-1, 92-2) are formed with engaging recesses (94-1, 94-2) on opposing faces to be engaged with a drawing-out member of a recorder. The center pin (91) and engaging members (92-1, 92-2) are integrally molded together from a material chosen from among synthetic resins such as POM, PA, and PC, with or without the addition of a reinforcing material such as glass fiber, metal, or metal oxide. Alternatively the center pin member (91) is in the form of a metallic solid pin having both ends of irregular profile other than circle, all formed in one piece at the time of synthetic resin molding. <IMAGE></p> |
