Tape reel for tape cassette |
摘要 |
A tape reel for a tape cassette capable of substantially preventing deformation thereof, even when it is thin-walled to substantially reduce a cycle time required for a molding step of the tape reel. The tape reel includes a reel hub and a disc-like flange. Reinforcing ribs include an annular rib arranged on an outer periphery of a disc-like flange and a plurality of linear ribs arranged on an outer surface of the disc-like flange so as to extend from a core stabilizing surface rib to the annular rib. The linear ribs are so arranged that each of the linear ribs intersects at least one of the other linear ribs at a position which is further than a midpoint between the core stabilizing surface rib and the annular rib.
