Claims

[Scope of utility model registration request]

A front cover that can be opened and closed on the front side of the cassette body is attached to the cassette body, and a locking member of the front cover is disposed in a gap between a side wall of the cassette body and a side wall of the front cover, and In the tape cassette configured such that the lock release member of the front cover is inserted into the tape cassette, the gap has approximately the same width from the front face of the cassette body to at least the lock release portion of the lock member, and A tape cassette characterized in that the width is larger than the gap and the tape cassette is dimensioned so as not to protrude from the side surface of the cassette.
