Abstract: A tape cassette is provided which has a rigid tape guide which provides for guiding the tape perpendicularly across the magnetic head of a tape machine. The cassette includes a casing body and cover with the tape guide mounted between. The tape guide is of unitary construction and includes a generally horizontally-extending, flat top section and a generally horizontally-extending, flat bottom section, spaced vertically apart from each other, and connected together by a generally vertically-extending support section. The tape guide includes a first roller support mount on one end and a second roller support mount on the other end. Each roller support mount includes both a pin for mounting a roller and a curved reinforcing member extending vertically therefrom. Both the pin and reinforcing member are formed integrally with the support mount.
