ABSTRACT:
A tape cassette for accommodating a magnetic recording tape comprises a casing including first and second major walls opposite to each other and spaced a distance corresponding to the width of a length of magnetic tape, a pair of opposite end walls, and front and rear walls opposite to each other, all assembled together to render the casing as a whole to represent a generally rectangular box-like configuration. Art erroneous erasure preventing member is accommodated within a detection hole, defined in the rear wall, for selective movement between retracted and projected positions in a direction substantially perpendicular to the rear wall. The erasure preventing member has an outer surface which, when in the projected position, closes the detection hole while lying flush with an outer surface of the rear wall, indicating the condition in which the magnetic tape contained in the tape cassette is available for information recording or erasure. On the other hand, when the erasure preventing member is moved to the retracted position with the outer surface thereof consequently set back inwardly from the rear wall, the tape cassette is held in the condition in which neither information recording nor information erasure can be accomplished on or from the length of magnetic tape contained therein.
