DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION This invention relates to an optical pickup lens cleaner for cleaning the pickup lens of the optical disk.

[0002]

2. Description of the Related Art Conventionally, a cleaning body such as a brush is implanted on a disk having the same shape as an optical disk to remove dirt from a pickup lens of an optical disk drive, and the brush is slid on the surface of the pickup lens by the rotational force of the disk. Various proposals have been made to make contact with each other.

At this time, it has been proposed to record BGM, a message, and the like on the board in order to inform a user that the board is being cleaned. It is also possible to record a function for reproducing an audio check signal other than the purpose of cleaning, for example, to improve the commercial value.

[0004]

By the way, in the case where music software is recorded, compatibility is ensured in the data recording method and the like. In such a case, even though the shapes and formats are the same, the microcodes of the data are different, so there is no compatibility between systems, and a CD-ROM dedicated to each system is used.

Therefore, when considering a pickup lens cleaner to which software such as image information is added, it must be dedicated to a specific system, and various systems are not versatile, inconvenient, and have the advantage of mass production. I can't use it. To eliminate these drawbacks,
Development of so-called hybrid CD-ROMs that can be used
In any case, such an optical disk drive

Is likely to occur. In particular, play information other than music
If this is attempted, this noise will be fatal and playback will not be performed at all.
There is a high possibility that it will not be done. Furthermore, in the playback state,
If the lens keeps contacting, cleaning will take a long time,
Not only is the usability worsened, but also a pickup lens
There is an adverse effect on it.

1 shows a pickup lens cleaner according to the present invention, in which a cleaning area 2 is provided on a disk 1 having the same shape as a CD, and a cleaning body 3 such as a brush is planted in the cleaning area 2. are doing. Cleaning area 2
Has a lead-in area 4 on the inner peripheral side of the TOC (Ta).
ble of Contents) is repeatedly recorded.

There is a first recording area 5 containing image information between the cleaning area 2 and the lead-in area 4.
A plurality of tracks a, b, c, and d exist in the first recording area 5 so as to be compatible with various systems.
Is a microcode compatible with the system A,
Programs, data, etc. are recorded. Similarly, tracks b, c, and d can be adapted to systems B, C, and D, respectively.

[0009] In the track e, programs, data, and the like are recorded according to a system E applicable to a plurality of types of systems. The outer peripheral side of the cleaning area 2
Are formed on the tracks a1, b1, c1, d1, and e1 so as to be compatible with various systems and methods A, B, C, D, and E, similarly to the first recording area 5. ing.

That is, a record conforming to the system A is formed on the track a and the track a1 with the cleaning area 2 interposed therebetween, and a record conforming to the system and method B, C, D, and E is formed in the cleaning area. 2 are formed on tracks b1, c1, d1, and e1, respectively.

When this pickup lens cleaner is used for cleaning the pickup lens 7 of the A system, the user performs an operation of reading the truck a after a predetermined starting operation of the A system. Since a program, data, and the like suitable for the system A are recorded on the track a, a target display as shown in FIG. 2 is performed on the screen of the system A.

As display examples, in addition to character information, a still image,
Moving images, voices, and the like can be considered, and information is transmitted to the user that the board 1 is to clean the pickup lens 7. Here, the user performs a predetermined operation according to the displayed cleaning method. The pickup lens 7 moves to the track a1 by a predetermined operation.

When moving from the track a to the track a1, the pickup lens 7 passes through the cleaning area 2, and the tip of the cleaning body 3 comes into contact with the surface of the pickup lens 7 to perform cleaning. The cleaning body 3 may be a felt material other than the brush material .

When the pickup lens 7 moves to the track a1, the cleaning is completed. Therefore, a program, data, and the like for displaying information indicating that cleaning is completed are recorded in the a1 track. Although it is possible to display information indicating that cleaning is being performed in real time on the screen at the time of actual cleaning, if a recording area is formed in the cleaning area 2, there is a risk of malfunction.

Therefore, in the cleaning area 2, no information is displayed on the system side, and after cleaning is actually completed, information indicating that the cleaning is being performed is reproduced by reproduction information on the track a1, and after a predetermined time, the cleaning is completed. It is preferable to reproduce the information shown. (See Fig. 3)

In this manner, the cleaning is completed, but in order to further increase the added value, another game or database software compatible with the system A may be additionally recorded. In this case, it is possible to record continuously on the track a1, but a track suitable for the system A may be formed separately.

In this way, adaptation in the system A is possible. However, if the cleaner is used in the system B, the tracks b and b1 on which programs and data conforming to the system B are recorded exist. Similarly, a cleaner having added value can be realized.

The same applies to the C system, the D system, and the E system. In this embodiment, five types of systems and methods have been described. However, it is needless to say that the number of systems and methods to be adapted becomes arbitrary by changing the number of tracks.

The shape of the board 1 may be 12c depending on the purpose.
In addition to the mCD, the shape of an 8 cm CD or another optical disk may be used.
It can be used for cmCD devices and is very convenient.

The present invention can be practiced even with a cartridge. In this case, it is desirable to avoid applying unnecessary contact force to the cleaning member implanted on the inner surface of the cartridge and the disk surface of the optical disk.

FIG. 4 shows an embodiment of a cartridge type pickup lens cleaner. The cartridge body includes a lower case 9 and a door 10, and the door 10 is a hinge 1.
1 is rotatable. The lower case 9 is provided with a shutter 12 and is opened and closed in conjunction with the insertion / removal operation of the cartridge. When the board 1 is set in the cartridge body and inserted into a disk drive (not shown), the signal surface of the board 1 is exposed from the window 13 of the shutter 12.

The cleaning body 3 is implanted on the board 1 as described above. When the shutter 12 is closed, the projection 1 as a support for the board 1 formed on the shutter 12 is provided.
4a and the operation unit 1 linked to the opening and closing operation of the shutter 12
The board 1 is pushed up to the door 10 side by the projection 14b formed at the tip of 5 to prevent the cleaning body 3 from contacting the inner wall of the lower case 9.

When the shutter 12 is opened with the disk drive set, the abutment between the projections 14a and 14b and the disk 1 is released, and the disk 1 can be freely moved in the cartridge. No problem. In addition, the protrusion 14 b formed integrally with the shutter 12 and formed at the tip is also movable along a slot guide 16 formed in the lower case 9.

In the above-described embodiment, the projections 14a and 14b, which are formed integrally with the shutter, are brought into contact with the outer peripheral side of the panel 1 which is a non-signal portion. In addition to the protrusions 14a and 14b shown in the above-described embodiment, a roller-shaped supporting member may be provided so as to interlock with the shutter. In addition, the protrusion 14 as a support body interlocked with the movement of the shutter 12
Since the projections 14a and 1b are located at the outermost periphery of the board 1 and are moved in the tangential direction, the projections 14a and 1b are slightly moved.
4b moves easily out of the board 1, and a smooth support operation can be realized. According to such a structure, even if the cleaning body is planted on the board, the cleaning body can be properly accommodated in the cartridge case without damaging the cleaning body.

Of course, the above-mentioned embodiment is different from the above-described embodiment in that the type of the shutter and the shape of the case are different, for example, a so-called electronic book CD-ROM cartridge or a disk hub is formed of a magnetic material, and the drive side only from one side of the disk. It is needless to say that the present invention can be applied to a so-called mini-disc cartridge adopting the magnetic coupling method.

FIG. 5 shows another embodiment.
It is characterized in that a plurality of cleaning areas 24 and 25 exist. The cleaning body 21 is a so-called dry cleaning body that does not apply a cleaning liquid, and the cleaning body 22 is a so-called wet cleaning body that uses a cleaning liquid. The dry cleaning body 21 exists in the dry cleaning area 24 between the first recording area 5 and the second recording area 6, and the wet cleaning body 22
Exists in the wet cleaning area 25 between the second recording area 6 and the third recording area 23.

With such a configuration, software for selecting a cleaning menu can be recorded on each track of the first recording area 5 to realize cleaning according to the user's preference. For example, in the case of the system A, the recording of the track a21 is reproduced by a predetermined operation on the system side, and the screen shown in FIG.
Is displayed as shown in FIG. As a result, the user can perform desired cleaning.

That is, if the user selects 1 according to the screen display, dry cleaning suitable for the A system is performed. This is an operation in which the pickup 7 moves from the track a21 to the track a22 through the dry cleaning area 24. If the track b21 is reproduced by a predetermined operation in the B system, the screen is displayed as shown in FIG. 6B. If the user selects "7" in FIG. 6B, the software suitable for the B system is reproduced. Perform wet cleaning. This is when the pickup 7 is a truck b21
From the dry cleaning area 24 and the track b23 passing through the track b22 and the wet cleaning area 25.
This is the operation of moving to.

In this embodiment, the wet cleaning area 25 is disposed on the outer peripheral side of the dry cleaning area 24. When the dry cleaning is selected, the wet cleaning body 22 must be moved while the pickup 7 is moving. It does not pass through the area.

If the optical disk is writable,
It is also possible for the user to record the last cleaning use time and other information necessary for cleaning. In addition,
In each of the above embodiments, the cleaning area exists between the recording areas. However, in the case of the present invention, the cleaning area can be disposed at any position.
The cleaning body 28 may be planted in the lead-in area 4 as shown in FIG. At this time, the recording area 27 is located on the outer peripheral side of the cleaning body 28, and is a track a3 applicable to each system.
1, b31, c31, d31 and e31 are formed.

Therefore, if the user selects a suitable track in a predetermined start-up operation in each system, the software for displaying the cleaning state together with the cleaning can be reproduced.
