Claims

[Scope of utility model registration request]

In a tape cassette in which the upper half and the lower half have a window portion that includes a pair of reel shaft insertion openings and is larger than the maximum diameter of the tape wound around the reel hub, each window portion of the upper half and the lower half is When forming a transparent window plate by joining the hole, a triangular reference rib is provided on either one of the joint part of the window hole and the joint part of the transparent window plate, and a triangular reference rib corresponding to the triangular reference rib is provided on the other side. A tape cassette, characterized in that a recess is provided, and the transparent window plate is ultrasonically welded to the junction of the window hole in a state where it is positioned by the triangular reference rib and the triangular recess.
