FIG. 4 shows a CD-ROM according to an embodiment of the present invention.
1 shows an apparatus 10.

[0010] 11 is a front bezel, 12 is a chassis,
13 is a disk, 14 is a turntable-optical head unit.

The turntable-optical unit 14 has a structure in which a turntable 15, a motor 16, and an optical head 17 are incorporated.

As shown in FIG. 9, the CD-ROM device 10 has a front bezel 11 exposed and is incorporated in a computer device main body 20.

First, automatic loading of a disc will be described.

The CD-ROM device 10 has an automatic disk loading mechanism 30.

The mechanism 30 comprises a loading motor 31, a conical pulley 32, a conical rubber roller 33, a gear 34, a cylindrical cam gear 35, a lifting lever member 36, and the like, as shown in FIGS.

FIG. 7 shows an initial state. The unit 14 is inclined downward. The disc tray 13 protrudes outward from the opening 11 a of the front bezel 11.

The user places the disc 40 on the tray 13 and presses the button 37.

[0018] Thus, the motor 31 is started to forward rotation of the pulley 32, the rubber roller 33 is transmitted to the cylindrical cam gear 35 via a gear 34, which is substantially one revolution rotates in the A ₁ direction.

[0019] A rack 13a by the first rotation of one rotation slightly less than the cylindrical cam gear 35 is driven by a gear unit 35a, the tray 13 is moved to B _1, the disk 40 is CD-
It is carried into the ROM device 10.

[0020] The cylindrical cam gear 35 of subsequently turning the (final stage rotating), the lever member 36 is rotated in the C ₁ direction by the cylindrical cam portion 35b, horizontal unit 14 shown in FIG. 7 in the D ₁ direction Turned to the position, turntable 15
Moves up.

The disk 40 is supported by the turntable 15 and is clamped by the clamper 18.

The loading of the disk 40 is completed as described above. Subsequently, the disk 40 is rotated by the motor 16 and reproduced by the optical head 17.

When the button 37 is pressed again, the loading motor 31 starts and rotates in reverse, and the above-mentioned mechanisms operate in the reverse order to the above-mentioned loading and in the direction opposite to the above-mentioned loading. The disc 40 is released from the clamp after being released from the clamp.

Next, the main part of the present invention will be described.

FIGS. 1 and 2 show a disk emergency ejection mechanism 5.
Indicates 0.

FIG. 1 shows a state during emergency removal of a disk, and FIG. 2 shows a state during normal operation.

Reference numeral 51 denotes an emergency knob member, which has a shaft portion 51a and a conical roller portion 51b at the tip of the shaft portion 51a, as shown in FIG.

The shaft portion 51a has a constricted portion 51a-1 for receiving a spring in the middle thereof, and a groove portion 51 for screwing at an end.
a-2.

Reference numeral 52 denotes a leaf spring member, which has a base portion 52a and a U-shaped leaf spring portion 52b extending therefrom as shown in FIG. A U-shaped notch 52c is formed on the distal end side of the U-shaped leaf spring portion 52b.

At the front end side of the chassis 12 where the front bezel 11 is mounted, a mounting portion 12a for mounting the emergency knob member 51 and the leaf spring member 51 is formed.

As shown in an enlarged manner in FIG. 3, the mounting portion 12a has a front end side wall 12a-1 and a wall 12 facing the front end side wall 12a-1.
a-2 and recess 12 between walls 12a-1 and 12a-2
-3, U-shaped recess 12a-4 of wall 12a-2, and wall 1
It consists of a hole 12a-5 of 2a-1.

As shown in FIGS. 2, 4 and 5, the knob member 51 has the shaft portion 51a fitted to the U-shaped portion 12a-3, and the end side of the groove portion 51a-2 of the shaft portion 51a. Hole 12a
-5, and both ends of the shaft 51a are supported.

The leaf spring member 52 is fixed to the wall 1 by screws 53.
It is attached to the upper end surface of 2a-2.

The U-shaped leaf spring portion 52b is accommodated in the concave portion 12a-3, and the U-shaped notch 52c is formed in the constricted portion 51a-.
1 is fitted.

The base 52a covers the U-shaped recess 12a-4, so that the shaft 51a does not come off the U-shaped recess 12a-4.

The knob member 51 is provided with a U-shaped leaf spring portion 5.
By the spring force of 2b is urged E ₁ direction are displaced in the same direction, in the normal, as shown in FIGS. 2 and 5,
The roller portion 51b is separated from the rubber roller 33.

Therefore, the mechanism 30 includes the knob member 51
Are operated without rotating, that is, the knob member 51 does not become a load.

The front bezel 11 has a notch 11b as a turning member insertion portion at a position corresponding to the end of the shaft portion 51a of the knob member 51.

Next, in the state where the disk 40 is loaded as shown in FIG.
The emergency removal of the disk 40 will be described.

As shown in FIG. 9, the user inserts a flat screwdriver 60 as a turning member into the front bezel 11.
Into the notch 11b, and insert the tip of the driver 60 into the groove 5
1a-2, and turn in G direction (counterclockwise) while pressing in F direction.

[0041] By pressing in the direction F, as shown in FIG. 1, the knob member 51 is displaced in the E ₂ direction, the conical roller portions 51b press against the conical rubber roller 33.

By turning in the G direction, the roller portion 51b
Is transmitted to the rubber roller 33, and the rubber roller 33 rotates.

The rotation of the rubber roller 33 is transmitted to the cylindrical cam gear 35 via the gears 34, cylindrical cam gear 35 is A ₂
Pivoted in the direction.

[0044] When the cylindrical cam gear 35 starts to rotate in the A ₂ direction, first, the lift lever member 36 is rotated in the C ₂ direction by the cylindrical cam portion 35b.

[0045] Thus, the unit 14 is rotated in the D ₂ direction lowers the turntable 15, the disk 40 is unclamped, is placed on the tray 13.

[0046] When the cylindrical cam gear 35 is further rotated, the gear portion 35a drives the rack 13a, the tray 13 is moved in the B ₂ direction, protrudes forward by the front bezel 11.

The user grasps the tray 13 protruding from the front bezel 11 and pulls it toward the user.

Thus, the tray 13 is directly pulled out, and the disk 40 is taken out.

When the tray 13 is pushed after the disk is taken out, the tray 13 is pushed into the CD-ROM device 10.

It is to be noted that a configuration in which a dedicated turning member is used instead of the driver may be adopted.

The present invention is not limited to a CD-ROM,
The present invention can be applied to a device using a CD, an optical disk, a magneto-optical disk, and a magnetic disk.

[0052]

[Effects of the Invention] As described above, according to the present invention, in a state where the disc is mounted while being clamped ,
If a failure occurs in which the motor does not start, the disk drive can be manually operated from the front bezel side.
Lower the unit to release the disc clamp.
And then move the tray to eject the disc
To remove the disc.

Therefore, the disk can be taken out in an emergency even with the disk device incorporated in the computer body with only the front bezel exposed.

This means that when the computer is sent to the repair department, the disk can be collected and then sent, and the inconvenience of having to send the disk with the disk mounted can be eliminated. There is a feature that there is.
