Abstract
A tape cassette comprising an insertion opening disposed in a main body case and a detecting optical path, for detecting the leading and rear ends of a tape, interposed between the insertion opening and an optical path window formed in the left and right side walls of the case, wherein a first distinguishing member, rotatably inserted into an upper portion of the insertion opening, is supported to be vertically slidable, and a mechanism for holding the first distinguishing member in each state is disposed between the first distinguishing member and the main body case, thereby to allow a tape deck to have a simple internal construction even though the tape cassette is of a smaller size, and to provide a construction of the detecting opening preferable for detecting cassette information so that the tape cassette can be used in a compatible form.
