<p>PURPOSE:To easily eject a cassette from a cassette holder with a simple constitution by ejecting the cassette in the cassette holder with a toggle spring in which the direction of repulsive force is reversed in the case of performing a cassette ejecting action. CONSTITUTION:When a driving mechanism is driven and an arm 12 turns clockwise, the cassette holder 2 moves in a vertical upward direction and moves in a horizontal direction in the midst of movement. As the arm 12 turns more clockwise and the cassette holder 2 moves in the horizontal direction, 1st and 2nd levers 6a and 6b also turn. Then, the toggle spring 20 exceeds a dead point by the rotation of the 1st and the 2nd levers 6a and 6b just before the cassette 1 reaches an inserted position and the repulsive force of the spring 20 is reversed in a direction shown by an arrow I. The 1st and the 2nd levers 6a and 6b press the cassette 1 from its back so as to eject the cassette 1 from the cassette holder 2. Thus, the cassette can be easily ejected from the cassette holder in the case of performing the cassette ejecting action.</p> |
