Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cleaning body for removing dust adhering to an optical head.

[0002]

2. Description of the Related Art Optical discs and magneto-optical discs are used for recording sound information, image information, computer data and programs. These discs are set in a reproducing device or a reproducing recording device and rotated. It is designed to receive the reflected light of the emitted light. Since the surface of the lens body of the optical head is exposed to the internal space of the disk device, dust is likely to adhere to the surface, which is likely to adversely affect information recording or reproduction.

For this reason, conventionally, there has been proposed a technique in which a brush is planted in a base having a shape substantially the same as that of the disc board, the base is rotated, and the brush cleans the surface of the optical head.
Also, a compact disc (hereinafter referred to as C, which has a check signal recorded therein) for checking the performance of each device such as an amplifier and a speaker of AV equipment including the above-mentioned disc device.
D) exists. There are various check signals such as those for adjusting the left and right output balances and those for checking the frequency characteristics.

As described above, the members having the lens cleaning function and the check signal reproducing function described above are required for the maintenance of the disk device, but they are present separately and are inconvenient and expensive. Also improves. In order to have both of the above functions, it is conceivable to implant a lens cleaning member such as a brush in a part of the board on which the check signal is recorded. However, in this case, the cleaning member causes noise. The carefully recorded check signal may not be reproduced normally. In addition, the recording surface of the check signal must be cleaned with a cleaning cloth or the like as appropriate, but this also has the disadvantage that the cleaning member that is planted in it interferes with the cleaning.

[0005]

SUMMARY OF THE INVENTION It is an object of the present invention to eliminate the above drawbacks.

[0006]

According to the present invention, a cleaning area for cleaning a lens of an optical head and a check signal recording area are arranged on different positions as different tracks on the board, so that the respective areas can be arranged in different positions. In addition, since they exist independently in terms of signals, it is possible to combine completely different functions such as a lens cleaning function and a check signal reproducing function on one board, improving user convenience and reducing cost. Can be achieved.

[0007]

With this configuration, each functional area exists independently, and the dust attached to the lens surface is checked by sliding contact of the flocked body or by the wind pressure of the fan, and checking without replacing the disc. The signal is reproduced.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows a board 10 according to the present invention, which is 12c.
It has almost the same shape as mCD. A TOC (Table of Contents) area A, a start greeting message recording area B, a check signal recording area C, from the inner peripheral side of the board 10.
A cleaning area D and an end greeting message recording area E are provided independently for each track. Each area B, C,
D and E correspond to the track selection operation of the disk device 30, and specifically, the music selection buttons 1, 2, 3, of the disk device 30.
It corresponds to 4. A signal for listing the contents of the board 10 on the side of the disk device 30 shown in FIG. 2 is recorded in the TOC area A, and when the board 10 is set in the disk device 30, the optical head 20 in the device 30 will have this TDC. Area A
Start reading from. As the disk device 30, a CD
In addition to the player, a laser disk or a device having a reproducing function for both of them can be considered.

After reading the TOC area A, the optical head 20 moves to the greeting message recording area B which is the first track,
A message that informs the user how to handle the board 10 and the like is reproduced.

Specifically, "Thank you for purchasing ○○○ this time. When you press the song selection button 2, a check signal that allows you to check the AV equipment you are using is played. When button 4 is pressed, the optical head of the disc player used by the customer will be cleaned. "Will be played back to the user and the song selection button 31 in the disc device 30 used by the user will be displayed. , The correspondence of the function of the board 10 is notified.

Here, the user can individually select a desired function with the music selection button 31 in the disk device 30, but if the music selection button 31 is not operated, the user automatically moves to the second track. The check signal reproducing function works, and then the cleaning function of the lens 21 of the optical head 20 of the third track works.

In the check signal recording area C which is the second track, specifically, a system check signal capable of determining whether or not the system is properly connected, a high frequency and low frequency reproduction limit check, etc. are possible. Various signals are recorded. Finally, a message indicating that the reproduction of the check signal is completed is reproduced.

The cleaning area D, which is the third track, is composed of a sound part D1 and a soundless part D2 in which a message indicating that cleaning is to be started is recorded, and the emission direction is the longitudinal direction on the track in which the soundless part signal is recorded. Width 0.6m
m, a length of about 8 mm, and a flocked body 22 with a height of about 8 mm
Is planted, and the tip of the flocked body 22 is the lens 21.
Abut the surface of. (See Figure 3)

The sound part D ₁ on the inner peripheral side of the cleaning area D
Since a message to start cleaning is recorded in, the user is urged to open the message to start cleaning and select the music selection button 4 again.

When the music selection button 4 is selected, the end greeting recorded in the end greeting text recording area E, which is the fourth track, is reproduced by jumping over the cleaning area D selected by the music selection button 3. When the optical head 20 jumps over the cleaning area D, the lens 21 is moved in the radial direction while contacting the flocked body 22 rotating at high speed, and the lens cleaning is completed.

The operation of jumping over the cleaning area D is not essential, and the lens 21 is not required to jump over.
The flocked body 22 comes into contact with the hair and the cleaning is executed. In this case, the optical head 20 sequentially follows the silent portion D2 of the cleaning area D, so that the cleaning time becomes longer than that in the case of the interlace.

When the user uses the maintenance board 10 of the optical disk device having the above-mentioned structure,
First, the board 10 is set in the disk device 30. Board 1
If 0 is set and the user does nothing, the TO of the board 10
First, the signal recorded in the area C is used to reproduce the start greeting message recording area B of the first track. The user selects the music selection button 31 of the disc device 30 according to the content of reproduction.
Select. If the music selection button 2 is selected or left as it is, the signal of the check signal recording area C of the second track,
The voice or the like is reproduced, and the user can check the system and ability of the AV equipment used. At the end of the check, an end message will be sent. If lens cleaning is required, select song selection button 4 and select the optical head 20.
Through the cleaning area D of the third track to reproduce the end greeting of the fourth track. When the lens 21 of the optical head 20 passes over the cleaning area D, it abuts the above-mentioned flocked body 22 and is cleaned.

When only cleaning is desired, the board 10 is set and the music selection button 4 is selected immediately or during reproduction of the start greeting. Although the cleaning start message is recorded in the sound part D ₁ of the track 3, a guide text for selecting the track 4 is recorded therein, which is effective in avoiding a meaningless long time cleaning. .

The operation of each of the other music selection buttons is as shown in FIG. As shown in the above-described embodiment, according to the present invention, since the check signal recording area C and the cleaning area D are provided independently of each other in terms of arrangement and signal, maintenance of one board 10 can be performed easily. The user can arbitrarily exert the completely different functions for each of them independently or continuously, and in the case of this embodiment, a check signal is given to the inner peripheral side of the board 10. Since the recording area C and the cleaning area D are arranged on the outer peripheral side, the flocked body 2 is affected by factors such as model and timing.
If the optical head 20 moves from the inner circumference to the outer circumference even if 2 is determined to be a foreign substance and automatically stopped, one of the important functions, the check signal reproducing function, can be surely executed. Of course, the cleaning function is very convenient because cleaning can be executed with the rotational force until it is judged as a foreign substance and stopped.

Further, since the flocked body 22 is planted on the outer peripheral side of the execution area C of the check signal reproducing function, the dust removed by the cleaning moves outward due to the centrifugal force, and the check signal recording area C is formed. A good check signal reproducing function can be maintained without adversely affecting the surface.

Next, FIG. 5 shows that the cleaning area D is provided on the inner peripheral side and the check signal recording area C is provided on the outer peripheral side, contrary to the above-described embodiment. In this case, it is convenient that the cleaning effect of the flocked body 22 can be continuously and immediately confirmed in the check signal recording area C.

Further, the cleaning of the board surface in the check signal recording area is also easy because there is no obstacle such as the flocked body 22 on the outer periphery. Further, in this embodiment, the check function is always passed through the cleaning area when the check signal is reproduced, so that the cleaning function works every time. (See Figure 6)

FIG. 7 shows still another embodiment. This embodiment has substantially the same shape as the board of the above-mentioned embodiment, but the check signal recording area C on the inner peripheral side and the cleaning area D on the outer peripheral side are physically attached to and detached from the small board 40 and the donut board 41. It differs in that it is possible.

In the detached state, the cleaning area D is formed in a donut disk shape, and the check signal recording area is formed in substantially the same shape as a so-called single CD (8 cm CD). Therefore, if you want to use only the check signal playback function, donut board 4 with cleaning area D
It can be used as a single CD with 1 removed. Even a small single CD player can use only the check signal playback function.

Further, it is necessary to clean the surface of the board in order to sufficiently maintain the check signal reproducing function, but since the cleaning area can be removed so as not to damage the hair-implanted portion, it can be set in the automatic board surface cleaner. When the check signal recording area C and the cleaning area D are detachable,
Of these, the outer peripheral relationship is not limited to that in the above-described embodiment, and the inner peripheral small disk body may be the cleaning area D and the outer peripheral donut disk body may be the check signal reproduction area C.

Further, in the above-mentioned embodiment, the small board has a substantially single CD shape. However, if the small board has a substantially CD shape, a large disk board like a laser disk board can be considered as a whole.

Further, the detachable dividing method is not concentric, but the flocked body 50 is notched as shown in FIG. 8 (a), or the flocked body 22 is shown as shown in FIG. 8 (b).
Only the one may be removable.

In the above embodiments, the CD has been mainly described, but the optical disc may be a laser disc, a magneto-optical disc, etc. in addition to the CD, and may be used not only for music and images but also for computer data and program recording. Including. As a cleaning body for the optical head, a method in which a flow velocity of air is generated and dust is blown away by wind pressure may be considered in addition to the above-mentioned flocked body.

[0029]

As described above, according to the present invention, the cleaning area for cleaning the lens of the optical head and the check signal recording area are provided as separate tracks at different positions on the board, so that the lens cleaning function and the check signal reproduction are performed. It is possible to store completely different functions, such as functions, in a single board, which makes it easy to use and reduces the price.
