<p>Recording tape cassette has pivotable spring means including a record-lockout tab which blocks an opening when the spring means is cocked. When placed on a cassette deck, a fixed tang on the deck releases the cocking, allowing the spring means and its record-lockout tab to pivot to a retracted position, thus unlocking the opening. Thereafter, a feeler on the deck can enter that opening to disable the record function.</p> |
