Abstract

PROBLEM TO BE SOLVED: To improve the dust-proof effect of a front mount type optical disc driver with a simple construction by a method wherein the one-side ends of dust-proof members consisting of elastic plate-shaped materials are attached to the inside of the front panel of a housing and the other side ends are brought into tight contacts with a loading tray and the dust-proof members are provided above and below the loading tray. SOLUTION: A driver β drives a loading mechanism to draw a loading tray 106 out of the front opening 101b of a front panel 101a to the front of a housing 101 or into the housing 101 through the front opening 101b. At that time, the leader member 106d of the tray 106 is drawn out to the front of the housing 101 or drawn back into the housing 101 through an opening composed of dust- proof members 102 while the leader member 106d is brought into tight contacts with the dust-proof members 102. Therefore, as the tip parts 102a of the dust- proof members 102 are always brought into contacts with the tray 106, the penetration of dusts into the housing 101 while the disc is replaced or the loaded can be blocked. With this constitution, the dust-proof effect can be improved with a simple construction while an excessive load resistance is not applied to a loading motor and a mechanical unit.

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dustproof structure in a front tray loading type optical disk drive device.

[0002]

2. Description of the Related Art Conventionally, there has been an optical disk drive apparatus which employs a front tray loading type loading mechanism as a kind of optical disk drive apparatus.

A conventional front tray loading type optical disk drive device will be described with reference to the drawings. FIG. 3 is an overall perspective view of a conventional optical disc drive device, and FIG. 4 is a partially enlarged right side view of the same.

In the figure, α is an optical disk drive device, D is an optical disk recording medium, P is an optical pickup, 1 is a housing,
1a is a front panel, 1b is a front opening, 2 is a dustproof member, 3 is a chucking pulley, 4 is a clamper plate, and 6 is a loading tray.

The conventional optical disk drive device α shown in FIGS. 3 to 4 employs a front tray loading type loading mechanism and has a box-shaped housing 1
A front panel 1a having a front opening 1b through which a loading tray 6 having a disk storage recess 6a having a diameter slightly smaller than the outer diameter of the optical disk recording medium D is formed is provided on the front surface of the front panel 1a.

Inside the housing 1, the loading tray 6 is provided.
A loading mechanism (not shown) for horizontally driving the front surface of the housing 1 and the inside of the housing 1 through the front opening 1b so that the housing 1 can be stored therein; and a turntable for mounting the optical disk recording medium D on the upper surface for rotational driving. 3, an optical pickup P for recording / reproducing information recorded on / from the optical disc recording medium D, and a mechanism (not shown) pivotally supported inside the housing 1 to integrally move the turntable 3 and the optical pickup P up and down. A chucking pulley (not shown) for rotatably sandwiching the center hole Dh of the optical disc recording medium D between the unit and the upper surface of the turntable 3, and the housing 1
It comprises a clamper plate (not shown) that is rotatably supported inside and that hangs and supports the chucking pulley (not shown) from above.

A tip member 6d exposed on the surface of the front panel 1a is fixed to the tip of the loading tray 6, and a dustproof material 2 made of an elastic material is further provided on the back surface 6e of the loading tray 6 tip member 6d. Is attached so as to engage with a locking groove 1c that surrounds the front opening 1b of the front opening 1b, and when the loading tray 6 is housed inside the housing 1, the front opening 1b extends into the housing 1. Prevents the ingress of dust.

As described above, when the loading tray 6 is housed in the housing 1 and the disk is driven to rotate,
The dustproof material 2 closes the space between the front panel 1a surface and the tip member 6d of the loading tray 6 to maintain the airtightness of the housing 1, so that the entry of dust into the housing 1 is prevented.

As described above, in the conventional optical disk drive device α, the dustproof material 2 is disposed on the front end member 6d of the loading tray 6 and the rear surface 6e.

[0010]

However, the above-mentioned conventional optical disk drive device α has the following drawbacks. That is, the first drawback of the optical disk drive device α is that since the dustproof material 2 is attached to the front end member 6d of the loading tray 6 and the rear surface 6e thereof, the dustproof material 2 and the locking groove 1c may depend on the mounting tolerance of the loading tray 6. There is a drawback that the dustproof effect is insufficient due to the formation of a gap between them.

The second point is that the loading tray 6 is always urged to the inner side of the housing 1 in order to maintain the airtightness in the disk rotation driving state, that is, in the state where the loading tray 6 is housed inside the housing 1. However, there is a drawback that an extra load is applied to the loading mechanism unit (not shown).

Thirdly, since the dustproof material 2 is required to be attached to the back surface 6e of the tip member 6d of the loading tray 6, a smooth surface having a predetermined area is required.
There is a drawback that the exposed dimension of d on the front panel 1a surface is enlarged and the structure and design of the optical disk drive device α are limited.

As a fourth point, the dustproof material 2 has to be attached to the peripheral portion of the front end member 6d of the loading tray 6 having a small attachment area and the rear surface 6e.

An object of the present invention is to provide an optical disk drive device having a high dustproof effect and a simple structure.

Next, the optical disk recording medium D is recessed in the disk storage recess 10 on the upper surface of the loading tray 106.
Place on 6a.

Next, when a loading mechanism (not shown) is driven to pull the loading tray 106 into the housing 101, the leading end member 106d of the loading tray 106 is pulled.
However, since it is pulled back while closely adhering to the dustproof material 102 having the opening formed therein and is housed inside the housing 101, intrusion of dust into the housing 101 in the loading state is prevented.

Next, the turntable 103 and the optical pickup P are inserted into the through hole 106d of the loading tray 106 from below to above, and the turntable 103 is fitted into the center hole Dh of the optical disc recording medium D from below. Then, the optical disc recording medium D is lifted while being rotatably mounted on the upper surface of the turntable 103, and the optical pickup P approaches the lower surface of the optical disc recording medium D.

Then, the spindle motor 104 is energized to rotate the optical disc recording medium D integrally with the turntable 103, and the optical pickup P is moved along the recording surface of the optical disc recording medium D to record / reproduce data.

Even in this state, since the dustproof material 102 is in close contact with the leading end member 106d of the loading tray 106, dust is prevented from entering the casing 101 in the disk rotation drive state. On the contrary, at the time of the eject operation of the optical disc recording medium D, the procedure reverse to the above description is performed.

As described above, in the optical disk drive device β of the present embodiment, since the tip 102a of the dustproof material 102 is disposed inside the housing 101 so as to be constantly in contact with the loading tray 106, it is applied to a loading motor and a mechanical unit not shown. The increase in load resistance can be suppressed as much as possible, and dust can be prevented without being restricted by the structure of the tip member 106d of the loading tray 106.

[0029]

As described above, according to the optical disk drive device of the present invention, there is an advantage that the dustproof effect can be exhibited without giving an excessive load resistance to the loading motor and the mechanical unit.

Further, there is an advantage that the size, structure and design of the tray panel are not limited.

Further, as compared with the conventional method in which the dustproof material is mounted on the back side of the tray panel, the mounting space can be made sufficiently large, so that workability is improved and cost can be reduced.
