Then, the operations (c) and (d) in each drawing are performed as described in FIGS. 6 and 8. Here, since the centers of the small cartridge 91 and the disks 92 and 93 are the same as described above, the height of the disks 92 and 93 is a problem, but as shown in FIG. The mounting surface 42 and the mounting surface of the disk 92 are the same, and the disk 91a of the small cartridge 91 is held by the turntable 20 at a position higher than the mounting surface 42. Held higher, the disc 92
Does not contact the mounting surface 42. Similarly, since the disc 93 placed on the lower placing surface 45 is held on the same plane as the disc 92, it does not come into contact with the placing surface 45 as a matter of course.

After recording / reproducing, the cartridge 90,
When ejecting 91 and the discs 92 and 93, the eject load switch 94 is pressed, and as shown in FIG. Then, the tray 1 is ejected. At this time, the height of the large cartridge 90 does not change, but the cartridge 91 and the disks 92, 93 are in a state of being lowered to the original mounting place of the sub-tray 1a.

11 to 13 show details of the disc engaging portion 5 shown in FIG. That is, the disc engaging portion 5 is located at the lower end side of the large disc 92 of the sub-tray 1a of the holding surface of the tray 1 in the vertical posture shown in FIG. 1 and at the two mounting surfaces in the moving directions Y1 and Y2 of the tray 1. It is provided at a position intersecting the edge 43 of 42. In FIG. 11, reference numeral 100 denotes a cylindrical portion formed at a position where the disc engaging portion 5 of the sub-tray 1 a is mounted, and the edge portion 4 of the mounting surface 42.
It is provided on the outer side of the tray 3 and projects to the bottom side of the tray 1. 1
Reference numeral 01 denotes a hole for escaping the tubular portion 100, which is formed on the bottom surface of the tray 1. Reference numeral 102 denotes a concave step portion formed at the lower end of the tubular portion 100, and 103 denotes a small hole formed at the upper end of the tubular portion 100 and penetrating the sub-tray 1a. Reference numeral 104 denotes a stopper member that fits into the recessed step portion 104, and has a protrusion-shaped spring support portion 10 at the center.
6. 107 is a spring member such as a coil spring,
One end is supported by the spring support portion 106. On the other hand, the disc engaging portion 5 is a tubular body that is rotatably inserted into the small hole 103, has a claw 108 that extends in the radial direction at the upper end, and has a protrusion 109 that projects in the radial direction at the lower end, Spring member 1 inside
The end of 07 is detachably fitted. Therefore, the disc engagement portion 5 is provided in the tubular portion 100 so as to be retractable and retractable, and is also biased to project by the spring member 107.

In FIG. 12, reference numeral 110 denotes a concave portion which is formed at the edge of the small hole 103 and through which the protrusion 109 can be inserted. Therefore, in the disc engaging portion 5, the protrusion 109 has the concave portion 110.
It is removably inserted through the small hole 103 so as to pass through. 1
Reference numeral 11 denotes a concave portion formed lower than the mounting surfaces 40 and 42, and is formed in a fan shape in consideration of the rotation range of the claw 108.

FIG. 13 is a sectional view taken along the line AA of FIG. 12, and is a developed view of the inside of the inner peripheral surface of the tubular portion 100 as seen in the axial direction. As is apparent from this figure, an inclined surface 112, which is a cam groove, is formed continuously in the circumferential direction from the recess 110 into which the protrusion 109 is inserted, and a horizontal locking surface 113 is formed at the end thereof. Therefore, by inserting the disc engaging portion 5 through the small hole 103, pushing it against the spring member 107, and rotating it, the projection 109 can be locked to the horizontal surface 113 and the claw 108 can be sunk into the concave portion 111. By pushing the claw 108 in the circumferential direction and rotating the disk engaging portion 5, the projection 109 slides on the inclined surface 112 and reaches the horizontal locking surface 113, which also causes the claw 108 to be in the retracted state from the projected state. Can be submerged in.

12 and 13, the spring member 107 can hold the protruding state of the disc engaging portion 5 without providing a horizontal surface between the recess 110 and the inclined surface 112. When the horizontal surface is provided, the disc engaging portion 5 can be more securely prevented from coming off. Further, the cam groove may be formed as a spiral groove having the inclined surface 112 as one side instead of the inclined surface 112. Furthermore, the inclined surface and the spiral groove are formed in the tubular portion 1.
00 may be formed on the outer peripheral surface of the disk engaging portion 5 that faces the inner peripheral surface of 00, and the protrusion 109 may be provided on the cylindrical portion 100 side.

FIG. 14 shows the protruding state of the disc engaging portion 5. The disc engaging portion 5 is biased by the spring member 107 so that the protrusion 109 is slidably in contact with the inclined surface 112. Mounting surface 40
The edge 43 intersects the edge 43 and extends onto the mounting surface 42 of the large disk. This is achieved by setting the positional relationship among the protrusion 109, the claw 108, the recess 110, and the inclined surface 112. The protruding posture of the disk engaging portion 5 makes it possible to support the peripheral edge of the large disk 92.

FIG. 15 shows a state in which the disc engaging portion 5 is depressed. When the claw 108 is rotated from the state shown in FIG. 14 to the outside of the mounting surface 42 as shown in FIG.

The claw 108 can also be sunk by pressing in the axial direction as it is in the state of FIG. 14 and then rotating to lock the projection 109 on the locking surface 113. As a result, the cartridge 90 can be mounted on the mounting surface 40 without the disc engaging portion 5 interfering. Further, in any of these cases, when the operation force applied to the disc engaging portion 5 is released, the biasing force of the spring member 107 causes the operation shown in FIG.
Although it projects to the state of FIG.
In this state, the projection 109 is engaged with the locking surface 113 and the retracted state is maintained. At this time, the claw 108 is positioned closer to the mounting surface 40 than the edge 43 so as not to interfere with the disc when the tray 1 is taken in and out in a horizontal posture.

16 to 19 show the case where the cartridge 90 and the disk 92 are mounted. 16 shows a case where the cartridge 90 is held in the cartridge mounting portion 3, and is also an example in which the cartridge 90 is mounted in FIG. That is, since the cartridge 90 is held by the clamping force of the piston spring 31, the tray 1
It can be used for both horizontal and vertical postures. At this time, the claw 108 is at a position lower than the mounting surface 40.

FIG. 17 shows a procedure for mounting the cartridge 90 on the tray 1 with the disc engaging portion 5 protruding. That is, FIGS. 9A and 9B show a state in which the tip of the cartridge 90 is applied to the claw 108 on the housing 2 side along the bottom surface of the holding surface of the sub-tray 1a in the direction of the recording / reproducing position. Since the tip of the claw 108 is located on the front end side of the tray 1 with respect to the center of rotation as shown in FIG. 7A, the disc engaging portion 5 rotates with respect to the small hole 103 in the direction of the arrow.
Therefore, the projection 109 slides on the inclined surface 112 of FIG. 13 and the disk engaging portion 5 sinks. FIG. 7C shows a state in which the tip of the cartridge 90 rides on the upper surface of the disc engaging portion 5 when the disc engaging portion 5 is retracted, and FIG. 7D shows that the tip of the cartridge 90 slides further forward. Then, the rib 41 of the cartridge mounting portion 3 is applied, and the front side of the cartridge 90 is engaged with the front wall 25 of the tray 1 with the rib 41 as a fulcrum. At this time,
The disc engaging portion 5 on the front end side of the tray 1 is a cartridge 9
When the tray 0 is loaded into the tray 1, the tray 1 is directly sunk against the spring member 107. Since the procedure for loading the cartridge 90 as described above is the same as the procedure for the case where the disc engaging portion 5 is not provided, it can be seen that the operability is good. When the cartridge 90 is taken out, the notch 7 is used in the reverse order of the above, but both the disk engaging portions 5 are projected by the action of the spring member 107. Therefore, it is possible to mount the disc 92 on the tray 1 immediately after removing the cartridge 90.

It goes without saying that the cartridge 90 may be mounted after the disk engaging portion 5 has been submerged in the above-described manner. FIG. 18 shows the case where the disc 92 is placed on the tray 1 in the horizontal posture. At this time, the disc engaging portion 5 sinks and the claw 108 is separated from the mounting surface 42, so that the disc 92 can be mounted without any trouble. Therefore, when the disc engaging portion 5 is sunk, when the tray 1 is used in a horizontal posture, the disc 92 or the cartridge 90 is selectively mounted on the tray 1 in the same manner as in the state in which the disc engaging portion 5 does not exist at all. be able to. Needless to say, it is not necessary to remove the claw 108 from the position of the mounting surface 42 when the sinking amount of the disc engaging portion 5 is set to be lower than that of the mounting surface 42.

FIG. 19 shows a case where the disc 92 is mounted on the tray 1 in the vertical posture. In this case, as shown in FIG.
