<p>The switching-over device allows reliable switching-over from change mode to automatic play mode with just a few components. The functions of the stack spindle (1) are controlled from below by means of pressure sleeves (3, 5). A command disc (13) controls the pick-up arm movements and raises the pressure sleeves (3, 5) via command levers (15, 17) for controlling the stack spindle (1). In a changing operation, the command lever (15) presses the pressure sleeve (5) upwards. In so doing, a slide (49) is pushed to the right via a tipping lever (35) and a driver pin (43). A blocking pin (57) of the pick-up arm mechanism is thereby released, so that the pick-up arm can swing over the newly placed-on record. When the last record has been ejected, the command lever (15) can perform only half a stroke upwards. In this case, the displacement is not sufficient to push the slide (49) far enough to the right. In this case, the slide (49) blocks the pick-up arm mechanism. <IMAGE></p> |
