As a result, the disc D in the disc pack 1 is moved by the slider 22.
As shown by the alternate long and short dash line in FIG. 4, the disc pack 1 is moved to the opening 3 side.

The slide lever 67 can be moved by the mechanism described below. To explain such a mechanism with reference to FIG. 5,
A partially-toothed gear 69, which is not partially formed with teeth, is pivotally attached to the rising portion of the movable chassis 66. A roller 70 is attached to the partially toothless gear 69 at an eccentric position, and this is inserted into an elongated hole 71 formed in a slide lever 67,
As a result, the slide lever 67 is engaged with the eccentric position of the partially tooth-chipped gear 69 via the roller 70. A gear 72 is also mounted on the rising portion of the movable chassis 66, and an arm 73 is rotatably supported by the gear 72. A shaft 74 is fixed to the tip of the arm 73 so as to project from both sides of the arm 73.
The part projecting from one surface is located in the through hole 75 provided in the rising part of the movable chassis 66, and the gear 76 is rotatably attached to the part projecting from the other surface. There is. This gear 76 is a small diameter tooth portion 72a of the gear 72.
, And also engages the arm 73 via a friction member, not specifically shown here. The gear 76 and the partial tooth-chipped gear 69 mesh with each other in the range where the teeth of the partial tooth-chipped gear 69 are formed.

Further, a motor 77 for driving the gear 72 is arranged on the lower surface side of the movable chassis 66, and the driving force of the motor 77 is transmitted to the gear 72 via the intermediate gear group 78. ing. As shown in FIG. 4, the shaft 79 of the gear 72 is integrated with a drive roller 91 described later. Therefore, the motor 77 drives both the slide lever 67 and the drive roller 91.

Based on such a configuration, the motor 77 in the state shown in FIG.
When the gear 72 is started to rotate in the normal direction and the gear 72 is rotationally driven in the direction indicated by the arrow g, the arm 73 engaging with the gear 76 via the friction member has the shaft 74 restricted by the through hole 75. The gear 72 is rotated in the same direction as the rotation direction of the gear 72 until it reaches the state, and is tilted downward as shown in FIG. This allows

Is moved to a predetermined position, and as a result, the position shown by the alternate long and short dash line in FIG. 6 is taken. Further, the rotation of the partially tooth-chipped gear 69 in the direction indicated by arrow h in FIG.
Is a direction opposite to the direction indicated by the arrow i in FIG. 5 as the roller 70 moves downward from the position (indicated by reference numeral 70 ') indicated by the alternate long and short dash line in FIG. To a position indicated by the solid line in FIG. 6 so that the protruding piece 68 does not come into contact with the driven piece 26 of the slider 22. This is so that when the movable chassis 66 moves up and down, the part of the disk pack 1 and the like do not interfere with the movement of the disk delivery means including the slide lever 67 that moves up and down accordingly.

When the motor 77 rotates in the reverse direction and the gear 72 is rotationally driven in the direction shown by the arrow j as shown in FIG. 6, the arm 73 returns to the position shown in FIG. This allows the gears
76 meshes with the partial tooth-chipped gear 69, and the partial tooth-chipped gear 69 moves to the sixth
It rotates in the direction indicated by arrow k in the figure, and thereafter, as shown in FIG. 5, the meshing state with the gear 76 is released,
As a result, the slide lever 67 returns to its original position and stops.

The motor 77 remains in the operating state even after the movement of the slide lever 67 is stopped, and thereafter only the drive roller 91 is rotationally driven. As described above, in this example, since the mechanism using the partial tooth-chipped gear 69 and the like is used, it is not necessary to separately provide a motor for driving the slide lever 67 and the driving roller 91. The cost can be reduced, or the size and weight can be reduced.

Then, here, the disc pack 1 is mounted on the pack mounting base 30 of the disc changer mechanism, and the slide lever 67 corresponds to the selected disc D in order to send out the selected disc D in the disc pack 1. In order to move the slider 22 to the position where the slider 22 is arranged, the entire movable chassis 66 is driven by the motor 83.

The movable chassis 66 is guided by the guide shaft 110 with the feed screw member 81 inserted through the through hole 66a, and the disk mounting portion 28 is guided. It is moved up and down in a substantially vertical direction. In this case, the optical position detection sensor 87 fixed to the movable chassis 66 performs position detection by reading the slit 89a of the position detection plate 89, the movable chassis 66, based on the detection signal obtained from the position detection sensor 87, Therefore, the slide lever 67 can be accurately moved to the desired position of the slider 22.

Further, the disc D sent from the disc housing portion 4 of the disc pack 1 by the slide lever 67 constituting the disc feeding means is conveyed to the movable chassis 66 in the direction along the surface thereof and supplied to the disc mounting portion 28. In order to achieve this, there is provided a disk transfer means including a drive roller 91, a driven roller 92, a support plate 93, a link member 94, a stopper pin 95, a guide roller 100, and the like, and the movable chassis 66 has a clamp arm 96. , Its rotating shaft 96a, upper flange 9
