<p>PURPOSE:To stabilize cassette discharge over at ion by locking a discharge member by an inserting lever until termination of upward movement of an elevator and by moving the discharge member after termination of the upward movement of the elevator to perform cassette discharge operation. CONSTITUTION:When an eject lever 1 is operated from the play state as conventional, the elevator 11 is moved upward. When the elevator 11 reaches its upper position, an elevator roll 15 so far engaged with an end face 12a of a drop lever 12 is disengaged from the end face 12a to ride on the drop lever 12, which is energized by a spring 16 to be shifted by a prescribed amount in the direction shown by an arrow mark C. The insertion lever 14 connected to the drop lever 12 is turned clockwise, but the engaging parts 17, 19 are still engaged at the time when the upward travel of the elevator 11 is terminated. As the drop lever 12 is moved in the direction of the arrow mark C by a stroke after termination of the upward travel of the elevator 11, the engaging state is released. The discharge member 13 now freed is energized by a toggle spring 6 to be shifted in the direction of the arrow mark D to discharge the cassette.</p> |
