Description

Detailed Description of the Invention [Field of Industrial Application] The present invention relates to a disk drive device that records information on a disc-shaped disk mainly optically, magnetically, or electrically using electric signals. , Disc drive with this! This relates to the aII device.

[Conventional technology]

Video audio signals or various Q
Optical discs, on which information is recorded and reproduced using electrical signals, are housed in cartridges for portability, protection, and prevention of dust and the like. However, if the cartridge is left unattended or carried around, the dust around the cartridge and inside the cartridge will be carried into the disk drive and adhere to or scratch the disk, making it impossible to record and reproduce information correctly.

Furthermore, if a piece of dirt falls onto the pickup lens, actuator, etc., the drive device itself may be damaged in some cases, making it impossible to record and reproduce data.

Note that since discs such as CDs (compact discs) that are not stored in cartridges can be cleaned in advance, manual cleaner devices are provided that facilitate this cleaning.

However, these discs are not easily installed, and the operation is cumbersome as cleaning must be performed before the disc is installed.

[Problem that the invention seeks to solve]

As described above, dust adhering to a disk not only generates noise when recording and reproducing information, but also may damage the disk itself in some cases. Therefore, even if the area around the cartridge is cleaned in advance, it is difficult to remove the dust that has gotten into the cartridge, and the cleaning work itself is difficult. Moreover, it is difficult to remove dust from a disk mounted in the device. As described above, conventional devices have many drawbacks in terms of operation and performance.

[Means to solve the problem]

The present invention solves the above-mentioned drawbacks by providing a cleaning device in the drive device for cleaning the recording surface of the disk, and using an operating mechanism that automatically cleans the disk immediately after the disk is installed in the drive device. This aims to provide a drive device that is completely unaffected by dust on the disk and can always record and reproduce correct information.

〔Example〕

FIG. 1 is a bottom view of the Ff1 configuration of the present invention viewed from the back. ptS2 Figure (A) is a side view when the cleaning member of the present invention is in contact with the disk, and Figure 2 (B) is a sectional view when the cleaning member is separated from the disk, both of which are taken along the line in Figure 1. It shows the case of cutting at It, CD, and EF. Further, FIG. 3 is a perspective view similarly cut approximately at the center.

Hereinafter, the same components will be described with the same reference numerals in each figure.

The order of operation of the present invention is as follows: First, when the disk 1 is installed in the drive vc position, the shutter 5 of the disk cartridge is automatically opened, and then when the cleaning switch is turned on, the drive vc position is automatically opened.
After confirming that a disk is installed in the C position, a mechanism to be described later is activated to perform a cleaning operation. When this operation is completed, the drive device enters the normal play state, which is indicated by a lamp or the like, and when the drive switch is turned down, the play operation begins. Are these series of operations for pre-programmed control? This is possible by incorporating a microcomputer into the drive unit.

Further, as shown in FIG. 1, the disk 1 is stored in a cartridge 4. There is an information recording area on the surface of the disk 1 from the outermost recording circumference 2 to the innermost recording circumference 3. When the disk 1 is mounted on the drive device, the shutter 5 located at the center moves to the position shown in the figure. Then, the window of Cartrick 4 is opened, pickup 6 is placed, and pickup 6 is placed.
The sensor unit 7 is placed at a predetermined position on the recording area of the disc 1, and prepares for a play operation. Further, the disk 1 can be rotated around the center B by a drive device.

Next, the cleaning device of the present invention is installed in the drive device, and this device is constructed as shown in FIG. That is, a cleaning member 9 is attached to the holding member 8 and cleans the disk surface. The cleaning member is preferably made of materials such as brushes, crow feathers, rubber plates, pads, etc., and has a width sufficient to force/clean the recording area of the disk, and the holding member 8 supports the cleaning member 9. Constructed with the width necessary to hold -Y Trtlm Nj 幇黛ム * Q I-)

It is connected to the tip of the lever 12 by 1g.

This lever 12 can be rotated in the vertical direction centering on the rotation V and pongee 13, and the other end of the lever 12 is
b is connected to the movable piece 15 of the solenoid 14. The holding member 8 and the movable piece 15 of the solenoid 14, which are connected by pins lla and llb, can rotate slightly through elongated holes, respectively.
The holding member 8 can be moved up and down along the id 10. Further, as shown in FIG. 2, the side of the lever 12 connected to the holding portion 8 is constantly pulled downward by the spring 16. The cleaning device of the present invention is configured as follows.

When an electric signal is input to the slide/id 14, the movable piece 15
is attracted (downward in the drawing), thereby causing the lever 12 to rotate about the rotation axis 13 against the spring 16, pushing the holding member 8 upward along the id 10. The cleaning member 9 then comes into contact with the recording area on the surface of the disc 1, and the disc 1 rotates in this state. That is, the cleaning member 9 completes cleaning of the entire surface by making one rotation or more while cleaning the surface of the disk. Furthermore, it is effective to spray a cleaning agent on the surface of the disk in advance during cleaning, as shown in the figure. However, it is thought that it is possible to easily attach a nozzle to the holding member.

Next, other application examples of the present invention will be explained. Figure 4 (A
), 8! of the holding member 8 and its driving relationship excluding the cleaning member! The structure and operation are the same as the previous example. Figure 4 (
B) is a partial side view of an air outlet and a suction pipe as a cleaning member, showing a pressurized air outlet pipe 20 with a width that covers the recording area of the disk 1, and a suction pipe 21 arranged in parallel nearby. provided, each tube 22
．． Air is sent at 23. That is, pressurized air is sent through the tube 22r and is injected from the blow-off pipe 20 to blow off dust, and the dust is collected from the suction pipe 21. In this method, since there is no contact between the disk surface and the cleaning member, it is not necessarily necessary to use a structure in which the holding member 8 is moved by the slide/id 14 as shown in FIG. 4(^). That is, an air blower '1720 as a cleaning member is placed at a predetermined location within the drive device.
It is also possible to fix the suction pipe 21,
It can be made into a simpler rock groove. Further, as shown in Fig. f55, as a modification of the blowout tube and the suction tube, it is also possible to have a structure in which several blowout or suction /: In particular, when this method is applied to the blow-off pipe, the wind force of the nozzle in the blow-off pipe is strengthened, which is effective in increasing the cleaning effect. This pressurized air is sent by a pump or fan, and dust mixed in the air is removed by using an air filter, so that clean air is always used.

Next, the pond mechanism that makes the effects of the present invention more effective will be explained. Regardless of which cleaning member is used, a certain cleaning effect can be obtained by setting and operating the cleaning member on the rotating disk.

However, in order to make this more effective, it is preferable to vibrate the cleaning member left and right on the disk surface.An example of this vibration mechanism is shown in Fig. 16 (A) and Fig. 6 (B).

Slide rod 3 passes through the holes of these protrusions 30m and 30b.
1 is slidably installed. A support body 37 that holds a cleaning member 39 is attached to this slide rod 31, and can slide left and right between the protrusions 30a and 30b. Further, the cleaning member 39 has a width sufficient to cover the recording area of the disc. Further, the drive motor 32 is attached to a holding member 38, and a disc 33 is attached to the pongee of this motor 32 so as to rotate. A feeding bin 34 is placed eccentrically above the disk 33 at a position offset from the rotation axis of the motor 32. On the other hand, the protrusion 30
Transmission bins 35a and 35b are provided at the tip of the slide rod 31 passing through b, so as to sandwich the feed bin 34 therebetween.

The rotation of the drive motor 32 causes the disc 33 to rotate, and the transmission bins 35a, 35b are further rotated by the feed bin.
, and slide the slide bar left and right. In other words, it has a structure in which rotational motion is converted into sliding motion. This causes the cleaning member 39 to vibrate left and right on the disk surface, making the cleaning effect more effective.

The mechanism of the present invention described above can be easily realized by ordinary machining and electric circuits.

〔Effect of the invention〕

As described above, the present invention makes it possible to clean discs stored in cartridges, which was difficult in the past, and makes it possible to record and reproduce correct information and prevent damage caused by dust on discs. Narina. In particular, it has been impossible to clean the disk after it has been installed in the drive device 1, but by providing a cleaning device in the drive device, the present invention automatically cleans the disk and always leaves the disk free of dust. It became possible to use it. Moreover, these devices can now be provided at low cost and operating reliably using conventional mechanisms.
