ABSTRACT:
A tape cassette which protects the tape thereof from dust, and which can be accommodated in a small volume. This is achieved by providing both a front lid and an inner lid and by making a distance between a rotation axis of the cassette front lid and a cassette bottom surface greater than a distance between a surface of the tape stretched along the front of the cassette case and the rotation axis of the cassette front lid. In addition, a restriction plate is provided for restricting rearward movement of the tape stretched along the front of the cassette case.
