发明名称 Automatic record-lockout mechanism
摘要 Recording tape cassette has pivotable spring means including a rocord-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 unblocking the opening. Thereafter, a feeler on the deck can enter that opening to disable the record function.
