Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention relates to a cleaning body that removes dust attached to an optical head.

0002

[Conventional technology]

Optical digital devices are used to record sound information, image information, computer data and programs. A disk or a magneto-optical disk is used, and it can be loaded into a playback device or a playback/recording device. A mechanism in which a disk disc is set and rotated to receive the reflected light that is irradiated onto it. It has become. The surface of the lens body of this optical head is placed in the internal space of the disk device. Because it is exposed, it is easy for dust to adhere to it, which adversely affects the recording or reproduction of information. It's easy.

0003 For this reason, brushes have traditionally been installed on a base that has approximately the same shape as the disc disk to rotate the base. It has been proposed that a brush be used to clean the surface of the optical head. In addition, each of the amplifiers and speakers of AV equipment, etc., including the above-mentioned disk device, etc. Compact disc with recorded check signals to check equipment performance (hereinafter referred to as CD) exists. As a check signal, adjust the left and right output balance. There are various types such as those for adjusting the frequency and checking the frequency characteristics.

0004 In this way, for maintenance of the disk device, the above-mentioned lens cleaning is necessary. A component with a checking function and a check signal regeneration function is required, but each exists separately. However, it is not easy to use and also increases the price. Equipped with both of the above functions In order to clean the lens, use a brush or other tool to clean the part of the disc where the check signal is recorded. It is conceivable to install a cleaning member, but in this way, the cleaning member becomes a noise source. As a result, the carefully recorded check signal may not be reproduced properly. There is. Also, the recording surface of the check signal must be cleaned with a cleaning cloth, etc. However, this cannot be done properly because the installed cleaning materials get in the way. There is this inconvenience.

0003

[Problem that the idea aims to solve]

This invention aims to eliminate the above-mentioned drawbacks.

0004

[Means to solve the problem]

This invention has a cleaning area on the disc body for cleaning the lens of the optical head. By arranging the check signal recording area and the check signal recording area as separate tracks in different positions, Therefore, each region exists independently in terms of layout and signal, and therefore The disc body has completely different functions: a lens cleaning function and a check signal regeneration function. This makes it possible to improve user-friendliness and reduce costs.

[0005]

[Effect]

In such a configuration, each functional area exists independently, and dust attached to the surface of the lens When the cleaning function is activated by the sliding contact of the flocked body or the wind pressure from a fan, etc. In both cases, the check signal can be reproduced without replacing the disc.

[0006]

【Example】

Examples of this invention will be described below based on the drawings. Figure 1 shows a disc 10 according to this invention, which has approximately the same shape as a 12cm CD. Ru. The board 10 has a TOC (Table of Contents) area from the inner circumference side. A, Start greeting recording area B, Check signal recording area C, Cleaning area D, End Completion greeting recording areas 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 correspond to the track selection operation of the disk device 30. These correspond to the music selection buttons 1, 2, 3, and 4 of the music device 30. Figure 2 is in TOC area A. A signal for listing the contents of this disk body 10 is recorded on the disk device 30 side shown in FIG. When the disk body 10 is set in the disk device 30, the optical head 20 in the device 30 starts reading from this TDC area A. The disk device 30 is a CD player. In addition to the player, a laser disc or a device having a playback function for both may also be considered.

[0007] After reading the TOC area A, the optical head 20 reads the greeting message as the first track. Move to recording area B and send a message informing the user how to handle this disc 10, etc. is played.

[0008] Specifically, "Thank you for purchasing ○○○. . By pressing the song selection button 2, you can check the AV equipment used by the customer. A check signal will be played. Also, if you press the song selection button 4, the customer's Clean the optical head of the disc playback device. ” messages etc. The page is played back, and the user is asked to press the song selection button in the disk device 30 that he or she is using. 31 and the function of the panel body 10.

[0009] Here, the user selects the function he/she wants to use using the music selection button 31 in the disk device 30. Although it is possible to select each song individually, it is necessary to operate the song selection button 31. If so, the check signal playback function will automatically move to the second track, and then the third track will start. The cleaning function of the lens 21 of the optical head 20 works.

0010 Specifically, in the check signal recording area C, which is the second track, the system is A system check signal that can determine whether the connection is properly connected or not, as well as high and low frequency reproduction signals. Signals, etc. that can be used to check production limits, etc. are recorded. And finally check signal A message will be played indicating that the playback has finished.

[0011] The cleaning area D, which is the third track, displays a message indicating that cleaning is about to start. The track consists of a sound part D1 where a message is recorded and a silent part D2, and a sound part D2 where a silent part signal is recorded. On the rack, with the radial direction as the longitudinal direction, the width is about 0.6 mm, the length is about 8 mm, and the height is in the recess. A flocked body 22 of about 8 mm is implanted, and the tip of this flocked body 22 is connected to the lens 21. comes into contact with the surface of (See Figure 3)

[0012] Since a message to the effect that cleaning is to be started is recorded in the sound area D ₁ on the inner peripheral side of the cleaning area D, the user opens the message to the effect that cleaning is to be started and presses the music selection button 4 again. You will be prompted to select.

[0013] By selecting the song selection button 4, the cleaning selected with the song selection button 3 The end recorded in the end greeting recording area E, which is the fourth track, jumping over area D. The greeting will be played. When the optical head 20 jumps over the cleaning area D , the lens 21 moves in the radial direction while contacting the flocked body 22 rotating at high speed. Lens cleaning is complete.

[0014] Note that it is not necessary to jump over the cleaning area D; Even if it is not there, the lens 21 and the flocked body 22 will come into contact with each other, and cleaning will be performed. this place In this case, the optical head 20 sequentially tracks the silent portion D2 of the cleaning area D. , the cleaning time is longer than in the case of skipping.

[0015] Using the maintenance board 10 of an optical disc device having the above configuration. When a person uses the disc, the disc 10 is first set in the disc device 30. Set the board 10, and if the user does nothing, record it in the TOC area A of the board 10. Based on the received signal, the starting greeting recording area B of the first track is first played back. ing. The user selects the song selection button 31 on the disk device 30 according to the content to be played. Ru. Select song selection button 2 or leave it as is to check the second track. The signals, audio, etc. in the code recording area C are played back, and the user You can perform system checks, ability checks, etc. A completion message appears when the check is finished. If you need to clean the lens, select song selection button 4 and press the optical head. 20 over the cleaning area D of the third track to clean the end of the fourth track. play the message. The lens 21 of the optical head 20 passes through the cleaning area D. When it comes into contact with the above-mentioned flocked body 22, it is cleaned.

[0016]If only cleaning is desired, the music selection button 4 may be selected immediately after setting the disc 10 or during playback of the opening greeting. Note that a cleaning start message is recorded in the sound part _D1 of track 3, and a message indicating that track 4 is to be selected is recorded here, which has the effect of avoiding unnecessary long cleaning times. .

[0017] The operations of the other music selection buttons are as shown in FIG. As shown in the above embodiment, this invention has a check signal recording area C and a cleaning area. Since the monitoring areas D are provided independently in terms of arrangement and signal, one The panel 10 has completely different functions for maintenance, each independently. The user can activate it at will, even if it is present or continuous, and this In the case of the embodiment, the check signal recording area C is on the inner circumferential side of the disk body 10, and the cleaning signal recording area is on the outer circumferential side. Because the arrangement is in area D, the implant may vary depending on factors such as the model or timing. 22 is determined to be a foreign object and automatically stops, from the inner circumference to the outer circumference. For the moving optical head 20, one important function is check signal reproduction. Raw functions can be executed reliably. Of course, the cleaning function also detects foreign objects and shuts them down. Cleaning can be carried out with the rotational force required until it comes up, which is very convenient.

[0018] Furthermore, the flocked body 22 is implanted on the outer peripheral side of the execution area C of the check signal regeneration function. The dust removed by cleaning is moved outward by centrifugal force. The check signal can be reproduced without any negative effect on the check signal recording area C surface. Function can be maintained.

[0019] Next, contrary to the above embodiment, the cleaning area D is on the inner circumference side, and the check signal is on the outer circumference side. An example in which a recording area C is provided is shown in FIG. In this case, the crease caused by the flocked body 22 is It is convenient because the ning effect can be continuously and immediately confirmed in the check signal recording area C.

[0020] Also, when cleaning the board surface in the check signal recording area, it is also necessary to avoid obstructions such as the flocked body 22 on the outer periphery. Since there is no material, it is easy. Also, in this embodiment, after reproducing the check signal, Since the cleaning area is passed through, the cleaning function works every time. (See Figure 6)

[0021] FIG. 7 shows yet another embodiment. This example is almost the same as the body of the example described above. Regarding the shape, there is a check signal recording area C on the inner circumference side and a cleaning area D on the outer circumference side. The difference is that the disc body 40 and the donut disc body 41 can be physically attached to and detached from each other.

[0022] In the detached state, the cleaning area D is formed in the shape of a donut disk, and the cleaning area D is shaped like a donut disk. The signal recording area is formed in approximately the same shape as a so-called single CD (8cm CD). There is. Therefore, if you want to use only the check signal regeneration function, use the cleaning area. In the same way as setting a single CD with the donut disc body 41 having area D removed. Can be used. Also, even if it is a small single CD player, there is a check signal player. Only Noh can be used.

[0023] Furthermore, it is necessary to clean the surface of the board in order to maintain the check signal regeneration function sufficiently. However, the cleaning area can be removed to prevent damage to the flocked area, so automatic platen surface cleaning is possible. It will be possible to set it on Lina. Check signal recording area C and cleaning area When D is detachable, the relationship between the outer circumference and the inner circumference is not limited to the above embodiment. Cleaning area D for the small disk body, check signal reproduction area C for the donut disk body on the outer periphery side It's good as well.

[0024] Further, in the above embodiment, the small disk body is approximately single CD-shaped, but the small disk body is approximately C. In the D-shape, it is also possible to consider a configuration in which the entire disc body has a large diameter like a laser disc disc. Ru.

[0025] Furthermore, in the case of detachable parts, the dividing method is not concentric, but as shown in Figure 8(a). The hair transplant body 50 may be cut out, or only the hair transplant body 22 may be cut out as shown in FIG. 8(b). It may also be removable.

[0026] Although the above embodiments were mainly explained using CDs, optical discs other than CDs can also be used. There are discs such as laser discs, magneto-optical discs, etc., and they are also used not only for music and video but also for computers. This includes data for data, program recording, etc. In addition, it is recommended as a cleaning body for the optical head. In addition to the above-mentioned flocked body, a method that generates air flow velocity and blows away dust using wind pressure is also considered. available.

[0027]

[Effect of the idea]

As mentioned above, this idea is based on a cleaning agent for cleaning the lens of the optical head on the disk. The checking area and the check signal recording area are each located on separate tracks. Therefore, we have developed two completely different functions: a lens cleaning function and a check signal regeneration function. Noh can be stored on a single board, making it easy to use and reducing the price. It has this effect.
