EP-A-0,129,292 discloses a disk holder for a disk player comprising a plurality of spring loaded catches arranged circumferentially around the disk and which are moveable in a radial direction. The catches grip the disk so that as it is inserted into the disk player, the disk remains accurately centred on the holder.
a disk tray provided with a disk mounting part for mounting a disk, and configured to be translated with respect to the disk drive main body, said disk tray being for introducing a disk mounted on the said disk mounting part into the disk drive main body;
the disk mounting part of said disk tray comprising a main part having a dimension compatible with the disk, and enabling mounting of a disk horizontally when said disk drive is used in a horizontal orientation, characterised in that the disk mounting part further comprises:
extensions produced by extending said main part in a direction of the plane of the disk tray; and
fixed tongue parts extending with a vertical separation from the circumference of the extensions, like eaves hanging over the extensions, the tongue parts and the extensions accommodating a peripheral portion of a disk mounted on the disk tray in an upright position when the disk drive is used in an upright position and the tongue parts supporting said portion of a disk so that a disk mounted on the disk tray in an upright position is prevented from falling.
The disk drive as described above can be used in a level position or in an upright position. It is to be appreciated that no additional components are necessary.
Preferably the disk drive main body is provided with guide parts for guiding the disk mounted on the disk mounting part in an upright position so as to draw the disk toward the main part of the disk mounting part, when the disk is introduced into the disk drive main body. In the disk drive described above, the disk mounted on the disk tray in an upright position when the disk drive is used in an upright position is centered properly so that the mounting of the disk can be effected properly. It is appreciated that no additional components are necessary in the disk drive main body.
Preferably the disk drive main body is provided with guide parts for guiding the disk mounted on one of the disk mounting parts in an upright position so as to draw the disk toward the main part of the disk mounting part, when the disk is introduced into the disk drive main body. According to the disk drive described above, it is possible to use a selected one of a large-diameter disk and a small-diameter disk in a level position or an upright position.

Fig. 17 shows how a 12-cm disk is set in a disk tray when the disk drive is used in a 180° reverse orientation with respect to the orientation shown in Fig. 11;
Fig. 19 shows how an 8-cm disk is set in a disk tray when the disk drive is used in a 180° reverse orientation with respect to the orientation shown in Fig. 14; and
A 12-cm disk 31 or an 8-cm disk 32 is mounted on the disk tray 12 and loaded into the disk drive main body 11. As shown in Fig. 3, the disk 31 (32) loaded is clamped on the turntable 21 by the clamper 25 with a small separation from the disk tray 12 and rotated by the motor 22. Information on the disk 31 (32) is reproduced by the optical head 20.
The disk tray 12 has a 12-cm disk mounting part 40 on which the 12-cm disk 31 is mounted, an 8-cm disk mounting part 41 on which the 8-cm disk 32 is mounted, and an opening 39 for the turntable 21 and the optical head 20.
The 12-cm disk mounting part 40 comprises a main part 40-1 (see Fig. 7) having a diameter D1 of 12 cm, generally crescent shaped extensions 40-2 - 40-5 (see Fig. 7) produced by extending the main part 40-1 in the direction of the width of the disk tray 12 (in the X1 direction and the X2 direction), tongue parts 40-6 and 40-7 extending with a vertical separation from the circumference of the extension 40-2, tongue parts 40-8 and 40-9 extending with a vertical separation from the circumference of the extension 40-3, tongue parts 40-10 and 40-11 extending with a vertical separation from the circumference of the extension 40-4, and tongue parts 40-12 and 40-13 extending with a vertical separation from the circumference of the extension 40-5, the tongue parts 40-6 - 40-13 being like eaves hanging over the extensions 40-2 - 40-5.
The tongue parts 40-6 - 40-13 do not hang over the main part 40-1.
The extensions 40-2 - 40-5 also extend in the X1 direction and the X2 direction as far as the respective ends of the disk tray 12.
In an alternative description, the tongue parts 40-6 - 40-13 are provided with an "undercut" by hanging over the extensions 40-2 - 40-5 around the main part 40-1.
As shown in Fig. 5, gaps 44-1 and 44-2 between the tongue parts 40-6 - 40-13 and the extensions 40-2 - 40-5 have a dimension a which is generally equal to the thickness t1 (see Fig. 12) of the disk 31.
Specifically, the 8-cm disk mounting part 41 comprises a main part 41-1 (see Fig. 8) having a diameter D2 of 8 cm, generally crescent shaped extensions 41-2 - 41-5 (see Fig. 8) produced by extending the main part 41-1 in the direction of the width of the disk tray 12 (in the X1 direction and the X2 direction), a tongue part 41-6 extending with a vertical separation from the circumference of the extension 41-2, a tongue part 41-7 extending with a vertical separation from the circumference of the extension 41-3, a tongue part 41-8 extending with a vertical separation from the circumference of the extension 41-4, and a tongue part 41- 9 extending with a vertical separation from the circumference of the extension 41-5, the tongue parts 41-6 - 41-9 being like eaves hanging over the extensions 41-2 - 41-5.
The tongue parts 41-6 - 41-9 do not hang over the main part 41-1.
In an alternative description, the tongue parts 41-6 - 41-9 are provided with an "undercut" by hanging over the extensions 41-2 - 41-5 around the main part 41-1.
As shown in Fig. 5, gaps 45-1 and 45-2 between the tongue parts 41-6 - 41-13 and the extensions 41-2 - 41-5 have a dimension b which is generally equal to the thickness t1 (see Fig. 15) of the disk 32.
The tongue parts 40-6 - 40-13 and 41-6 - 41-9 are formed to be integral with the disk tray 12. Thus, the disk tray 12 has a one-piece structure. That is, no additional components are added.
The guide parts 50 - 53 are formed to be integral with the chassis 13.
The 12-cm disk 31 is mounted on the main part 40-1 without sitting on the tongue parts 40-6 - 40-13.
That is, the operation of the disk drive 10 is the same as the operation wherein a conventional tray is used. Thus, the present invention provides easy of use. The same thing applies to the case of the 8-cm disk described below.
The 8-cm disk 32 is mounted on the main part 41-1 without sitting on the tongue parts 41-6 - 41-9.
A portion of the lower end part 31a of the 12-cm disk 31 projects downward out of the notch 42. 31a-1 indicates the portion projecting from the disk tray 12.
The disk 31 is opposite to the clamper 25 in the disk drive main body 11 and supported thereby. Thus, the disk 31 is prevented from falling even without the support provided by the tongue parts 40-6 - 40-9.
Consequently, the disk 31 is ejected out of the disk drive main body 11 in a generally upright position, while being supported by the tongue parts 40-6 - 40-9 of the disk tray 12.
Another case is considered where a disk mounting parts 40 and 41 face the opposite direction, that is, the orientation of the disk is 180° reversed with respect to the orientation shown in Fig. 11.
The disk 32 has its lower end part 32b inserted into the gap 45-2 and supported in an upright position by the tongue parts 41-10 - 41-13.
In a variation of the above-described embodiments, the gaps 44-1 and 44-2 have a greater dimension a, and the gaps 45-1 and 45-2 have a greater dimension b. In this variation, too, the disk can be supported in a substantially upright position and can be rotated properly while being inserted into the gaps. This means that the present invention includes variations of the above-described embodiments wherein the guide parts 50 - 53 are not provided.
