Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a disk-shaped recording medium cleaning device for recording / reproducing information with a laser beam.

[0002]

2. Description of the Related Art There are various techniques for recording / reproducing information on / from a recording medium using a laser beam, such as a compact disc, a write-once disc, a phase change disc, and a magneto-optical disc. Medium is 1
It is provided on a substrate made of plastic (polycarbonate, acrylic) 2P or glass having a thickness of about 1.5 mm, and information is recorded / reproduced from this substrate side. The above-described mediums that have been conventionally used are easily charged because the substrate is generally made of a dielectric material.

When the above-mentioned substrate is charged, dust or minute dust adheres to the surface of the substrate and stains it, so that the laser light is not properly incident or reflected, which causes a problem in recording / reproduction. At present, the above-mentioned medium is contained and used in a case (cartridge case) with a shutter in order to avoid contamination and to facilitate handling. Then, the optical disk inserted together with the cartridge is automatically mounted horizontally at a predetermined position by the disk loading mechanism, and the shutter is opened to fix the optical disk in the case to the spindle. In this case, when the medium is inserted into the recording / reproducing apparatus, the shutter opens so that the medium is exposed. In other cases, the shutter remains closed to prevent dust from adhering from the outside air.

However, in the case of the cartridge case as described above, since a metal plate is used for the shutter, when the shutter is opened and closed, rubbing occurs between the case and the shutter, rubbing powder is generated, and the case and the shutter are opened. Adhere to. In addition, since the case itself is placed in a general environment such as an office, dust adheres to the environment. If the case is inserted into the recording / reproducing device in such a state, the dust will enter the recording / reproducing device, and the shutter will be opened further, and the dust will adhere to the exposed case or the disc itself, causing a problem in recording / reproducing. May occur.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems of the prior art, and an object thereof is to clean a cartridge case for accommodating a disk.

[0006]

The structure of the present invention for solving the above-mentioned problems is a device for cleaning a disk cartridge case as described in the claims and an optical information recording / reproducing device having the same. .

The present invention will be described in detail below with reference to the drawings. 1 and 2 show the outline of a cleaning device according to an embodiment of the present invention. The apparatus is composed of an insertion opening for inserting the cartridge 1 and a portion 4 for supporting the cleaning member 3. When the cartridge 1 is inserted through the insertion opening, the cleaning member 3 comes into contact with the cleaning member 3 for cleaning. The cleaning member used here is a static eliminator brush, which is held by the support portion 4. Similarly, as the static eliminating brush, one having a dielectric property in itself may be used, and a mechanism for allowing static electricity to escape to a supporting portion or the like via a shaft portion for rotating the brush may be used. Further, the cleaning member comes into contact with the cartridge case at the time of cleaning, and at this time, pressure may be applied to the cleaning member by using an appropriate means such as a spring.

The state of the cartridge case and the shutter at the time of insertion is normally cleaned with the shutter 2 closed as shown in FIG. 1, but may be cleaned with the shutter open. Further, it can be used together with a cleaning member for cleaning the disc itself. Further, when the cartridge case is inserted, the cleaning member can be rotated in the direction opposite to the inserting direction to improve the cleaning effect.

As a method of rotating the cleaning member, for example, a method of using a step motor, or a method of mechanically passing the force of inserting the case through the gear through the cleaning member and rotating the cleaning member can be considered. The cleaning member may be rotated by a method other than the example.

Next, FIG. 3 is a schematic view of a cross section when the example of the present invention is incorporated in a recording / reproducing apparatus. As shown in FIG. 3, by interlocking the lid 5 of the apparatus and the cleaning member,
In the state where the cartridge case 1 is not inserted, the cleaning member is installed at a position lower than the insertion slot until the lid 5 of the apparatus is closed up to FIG. 3, and the insertion slot is completely closed by the lid 5. There is. Further, the state when the cartridge case 1 is inserted is interlocked with the lid 5 as shown in FIG. 4, and is raised so that the cleaning member comes into contact with the case.

With this structure, the cleaning member does not obstruct the opening and closing of the lid 5, and the cleaning member can be used for cleaning when the case is inserted. However, when the same mechanism is incorporated in the recording / reproducing apparatus, the shutter is inserted while opening, so it is necessary to set the timing of opening the shutter and the position of the cleaning member to an appropriate state.

5 to 8 show another embodiment of the present invention. 5 and 6 schematically show an embodiment of the present invention in front and side views. Although the actual device is composed of a drive, a ventilation system, or an exhaust system and a power supply section, only the drive and the ventilation system will be outlined in this embodiment.

A cartridge case 1 is provided on the front surface of the drive.
An insertion port 8 for inserting / removing the cartridge is provided, or a blower port 9 for air blowing the cartridge case 1 is provided below the insertion port 8 (on the recording / reproducing surface side of the disc). This air outlet 9
It suffices that the size and width of the cartridge be such that dust and dirt adhering to the cartridge can be removed, and in particular, the width is preferably such that the airflow hits the entire surface of the cartridge.

As shown in FIG. 6, the flow of the air flow is the fan 10
The cartridge 1 hits the cartridge 1 through the lower part of the drive and the blower opening 9. At this time, by providing a blower system in the lower part of the drive, the flow of the air flow in the system can be enhanced, and the cooling effect of the drive can be enhanced.

It is basically preferable to use the air flow used here through the filter 11. However, if the inside of the drive can be prevented from being contaminated by increasing the airtightness of the drive, the outside air can be used directly. It is possible.

FIG. 7 shows another embodiment of the present invention. In this embodiment, as shown in the figure, a blower port 9 is provided at two positions above and below the cartridge insertion port 8, and a blower system is also provided at both upper and lower sides of the drive. The size and width of the blower port 9 should be such that dust and dirt adhering to the cartridge can be removed, and in particular, the width is preferably such that the airflow hits the entire surface of the cartridge. . By setting the blower ports 9 on the upper and lower surfaces of the cartridge insertion port 8 in this manner, it is possible to simultaneously blow air on the upper and lower surfaces of the cartridge 1.

Further, FIG. 8 shows an example in which the ventilation system is replaced by an exhaust system in contrast to the above embodiment. As shown in this figure, the exhaust port 12 is provided at the same position as the blower port, but the filter 11 is provided on the exhaust port side because the air flow is reversed. However, in the same structure, the area of the filter is
As it gets smaller, the frequency of cleaning or replacing the filter increases.

[0018]

As described above, by using the present invention, it is possible to effectively remove dust and dirt attached to the cartridge case and keep the inside of the recording / reproducing apparatus and the recording medium clean. Further, since the air flow can be positively created in the system, the temperature rise of the drive can be suppressed.
