  • Patent number: 4611258
    Abstract: A magnetic tape cassette apparatus having a pressure roller and a magnetic head on a head bracket, movable to a pause position in which the head contacts a tape in the cassette but the pressure roller is disengaged. Insertion of a cassette into a compartment tensions an ejection spring and a pause spring. A play bracket for moving the magnetic head into a playing position is latched by a pause latch in the playing position. The pause latch can be actuated and reset independently without changing tension in the ejection spring, for automatic unlatching and for easy reset to the playing position.

  • Patent number: 4564874
    Abstract: A magnetic tape cassette apparatus having a pressure roller and a magnetic head on a head bracket, movable to a pause position in which the head contacts a tape in the cassette but the pressure roller is disengaged. Insertion of a cassette into a compartment pivotally moves an ejection lever which is coupled to an ejection member so as to tension an ejection spring during movement of the ejection member from a rest position to an actuated position. A latching member latches the ejection member in the actuated position, leaving the ejection lever free to pivot relative to the ejection member, at least over a limited distance.
