<p>Recording tape cassette has pivotable spring means (21, 62, 90) including a record-lockout tab (23, 70, 91) which blocks an opening (24, 72, 92) when the spring means is cocked. When placed on a cassette deck, a fixed tang (36, 75, 96) on the deck releases the cocking (31, 32, 66, 68, 93), allowing the spring means and its record-lockout tab to pivot to a retracted position, thus unblocking the opening. Thereafter, a feeler on the deck can enter that opening to disable the record function.</p> |
