In the disk loading apparatus according to this embodiment, as shown in FIGS. 1, 2, 3, and 4 (a) and (b),
On the upper surface of the tray 1, a plurality of guide grooves 3 are engraved radially around the axial center position of the disk 2 (see FIG. 6 (a)) mounted on the tray 1, and each guide groove 3
A positioning member 4 having _a curved portion 4a for positioning the disc 2 on the upper surface of the tray 1 is movably provided in the disk. The positioning member 4, a retractable to the outer periphery of the concave disc supporting portion 1 _a of the disc accommodated formed on an upper surface of the tray 1 with respect to continuously recessed to recess 1 _b, the disc When the positioning member 4 is not used for positioning, the positioning member 4 is accommodated in the recess _{1b so as} to be flush with it, and does not interfere with the mounting and demounting of the disc. Inside of the positioning member 4, a pair of support members 4 _b downward and is extended to the distal end of the support member 4 _b, the guide is fitted from the groove 3 to the tray 1 and the engaging Engaging claw _4c
Are integrally molded. Therefore, when the positioning member 4 is mounted in the guide groove 3, the engaging claw _4c is pushed by pushing the engaging claw _4c into the guide groove 3.
_c are bent inward with respect to each other and are fitted into the guide groove 3, and engage with the tray 1. As a result, the positioning member 4 is slidably supported along the guide groove 3 of the tray 1. Then, the positioning member 4 is positioned at a predetermined position on the tray 1 by a click (not shown). The stop position by the click corresponds to the position of the mark provided on the tray 1 in advance according to various disc sizes.

The tray 1, the recording and reproducing apparatus disc 2 loaded in the main body to receive and retain to the disk mounting portion 1 _a, and the mounting and dismounting position of the disk 2 (see FIG. 6 (a)) and a loading position (6 (See FIG. 2 (b)) for transporting the disc 2 and is slidably mounted on the chassis 5. A slide member 6 having _a rack 6a (see FIGS. 7A and 7B) engraved on the tray 1 is slidably mounted in parallel with the sliding direction of the tray 1 with respect to the chassis 5. The slide member 6 is fixed to the tray 1 by the lock lever 7 while the tray 1 moves from the loading / unloading position of the disc 2 to the loading position. The sliding member 6 on the side surface of the (Figure 7) are engraved cam groove 6 _b and 6 _c are having a bent portion, the cam groove 6 _b, 6 _c
Are for swinging a disk lever 8 and an arm 9, which will be described later, downward.

At the center of the tray 1, a pair of cushion 8 _a for supporting the disk 2 _(Figure 8 (a), (b), (c) refer)
And a U-shaped disc lever 8 provided with a protrusion 8 _b . The disc lever 8 has a pin 8
_By inserting _c into a mounting hole (not shown ₎ of the tray 1, it is swingably supported with respect to the tray 1.
Further, a guide pin 8 _d provided at the rear end of the disc lever 8 is slidably fitted in the cam groove 6 _b of the slide member 6.

An arm 9 having a disc retainer 10 is provided at the center of the chassis 5, and the arm 9 has a pin 9
By being fitted in a mounting hole (not shown ₎ of the chassis 5, _b is swingably supported. The disc retainer 10 is constantly elastically urged upward by the elastic urging force of the coil spring 11 provided at the rear end of the arm 9. A guide pin _9a (see FIGS. 7 (a) and 7 (b)) is provided at the rear end portion of the arm 9, and the guide pin _9a allows the tray 1 to reach the loading position of the disc 2. Cam groove _{6c of the} slide member 6
Be inserted into.

A magnet (not shown) is attached to the lower surface of the disc retainer 10, and the magnetic force of the magnet causes the disc retainer 10 to turn into a turntable 1 described later.
The disc 2 is sucked to the 2 side, and is clamped by the turntable 12 and the disc retainer 10.

A loading motor 13 is provided inside the chassis 5, and a pinion 14 rotatably driven by the loading motor 13 meshes with the rack 6 _{a of the} slide member 6. Further, a spindle motor 1 for rotatably driving the turntable 12 for supporting the disk 2 is provided at a substantially central portion inside the chassis 5.
5 are deployed.

In FIG. 2, reference numeral 16 is a pickup for detecting an upper signal of the disk 2 loaded in the recording / reproducing apparatus main body.

The disk loading device of the present invention is constructed as described above.

Next, with reference to FIGS. 6 (a) and 6 (b), the operation of loading the disc 2 into the recording / reproducing apparatus main body using the loading apparatus will be described.

When the tray 1 is in the mounting and dismounting position of the disk 2, to the size of the disk 2 to be loaded on the recording and reproducing apparatus main body, each positioning member 4 along the guide groove 3 toward the center of the recess 1 _b slides Let Then, after the positioning member 4 is click-stopped at a predetermined position,
The disc 2 is placed on the upper surface of the tray 1. As a result, the disc 2 is easily positioned at a predetermined position with respect to the tray 1. In this case, the positioning member 4
By further sliding along the guide groove 3,
Various discs can be set in the tray 1 (see FIG. 5).

The disc 2 mounted on the tray 1 is supported by the cushion _8a and the protrusion _{8b on} the upper surface of the disc lever 8 (see FIGS. 8 (a) and 8 (b)). The positional relationship between the slide member 6 provided on the guide pin 8 _d of the disc lever 8 and the guide pin 9 _a of the arm 9 is
The state shown in FIG. 7 (a) is obtained.

Then, the loading motor 13 causes the pinion 14 to move.
When the tray 1 is rotationally driven and the tray 1 is slidably driven in the direction of the arrow 17 to reach the loading position of the disk 2, the tray 1 is stopped, but only the slide member 6 is released by releasing the lock lever 7. Further, it is slidably driven in the direction of arrow 17. When the relationship between the guide pin 9 _a of the slide member 6 and the guide pins 8 _d and the arm 9 of the disc lever 8 is in the state shown in Figure No. 7 (b), the tip portion of the disc lever 8 is downwardly Is oscillated toward (see Fig. 8
(See (c)), the disc holder 10 of the arm 9 is also driven to swing downward.

As a result, the disc 2 is placed on the upper surface of the turntable 12 and is sandwiched between the turntable 12 and the disc retainer 10. Then, the disk 2 is rotationally driven by the spindle motor 15, and the information signal of the disk 2 is detected by the pickup 16.

[Effect of device]

As described above, the present invention provides a disc loading apparatus for holding a disc to be loaded in the recording / reproducing apparatus main body and having a tray for transporting the disc between the loading / unloading position and the loading position of the disc. A concave disc mounting portion for accommodating a disc is formed on the upper surface of the tray, and a plurality of recesses continuous with the disc mounting portion are formed at appropriate intervals on the outer periphery of the disc mounting portion. Guide grooves extending from the recess toward the center of the disk mounting portion are formed, and positioning members movable along the guide grooves are provided, and the positioning member protrudes inside the recess to outside the recess. It is possible to store the disc without moving the disc, and when the disc with a small diameter is loaded, the disc is moved from the recess to position the disc. Since a loading device of click can hold different sizes of disks, respectively, loaded in the recording and reproducing apparatus.

Further, in the apparatus, when the positioning member is not used for positioning the disc, the positioning member is housed in the recess, so that there is no hindrance when attaching or detaching the disc, and the workability is deteriorated. Nor.
