Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cleaning device for a disk cassette used to store and use a disk.

[0002]

2. Description of the Related Art For transporting aluminum and glass disks used as computer memory boards,
A cassette made of synthetic resin is used, and an example of this is shown in FIG.
29, the cassette 1 has left and right side plates 2 and 2.
And front and rear side plates 3 and 3, the front and rear side plates 3 and 3 are provided with a substantially U-shaped notch opening 4 , and the lower side has a width between the left and right side plates 2 and 2. A plurality of longitudinal grooves 5 are formed side by side on the inner surfaces of the left and right side plates 2 and 2 which are narrowly formed, and the lower sides of these grooves 5 are arcuate inward. Then, the disc 6 is inserted into the groove 5 to be engaged and supported, the upper opening (not shown) and the notch opening 4 of the cassette 1 are closed by an upper lid (not shown), and the lower opening 8 of the cassette 1 is opened by a lower lid (not shown). It is closed and the cassette 1 containing a plurality of disks 6 is transported.

Since the cassette 1 as described above is repeatedly used, if the cassette 1 becomes dirty, dust or the like will adhere to the disk 6 stored inside, and the cleanliness of the disk 6 will deteriorate. Therefore, conventionally, the cassette 1 is manually washed. However, since it is done manually, there is a problem that efficiency is poor and uniform cleanliness cannot be obtained.

On the other hand, while the cassette 1 is manually cleaned, various cleaning devices have been developed for cleaning the disc 6 and the like.
For example, in Japanese Utility Model Publication No. 4-22411, in order to clean a disk-shaped object to be cleaned, a cleaning tank located closest to the supply port uses a detergent as a cleaning liquid, and the cleaning tank is exposed to the detergent heated by a heater. The cleaning object is ultrasonically cleaned while oscillating, and the second cleaning tank is a scrubber cleaning tank for cleaning the cleaning object with a brush. The third cleaning tank uses pure water. The cleaning is performed by dipping and rocking the object, and the fourth cleaning tank is ultrasonically cleaned while the object to be cleaned is immersed in the organic solvent and rocked, and the fifth cleaning tank is cleaned with the organic solvent. It is a cleaning tank that is immersed and rocks when used, and the sixth cleaning tank is a steam tank that uses the vapor of an organic solvent (publication column 4, lines 21 to 37). Is equipped with a spray pipe for supplying water to the brush (publication column 5, column 23 to 2). 4 lines).

Similarly, as a cleaning device for cleaning the disk 6 and the like, in JP-A-63-86177, a turntable capable of holding a work by an air chuck is arranged so as to be rotatable by a drive source such as a motor. Then, above the turntable, at least one cleaning nozzle for injecting a cleaning liquid onto a work and a drying nozzle for injecting a drying gas are disposed so as to be displaceable in the radial direction of the work over time (Japanese Patent No. A cleaning device according to the claims is proposed. In this cleaning device, spin drying is performed by the injection of nitrogen gas from the drying nozzle and the centrifugal force accompanying the high speed rotation of the turntable (publication page 3, upper right column, number 13). ~ Line 15).

A large number of disk cleaning devices have been developed as described above, and automation of cleaning has been attempted. However, since the cassette 1 is manually cleaned as described above,
It was inefficient. Even if the above-mentioned disk cleaning device is used for cleaning the cassette as it is, the cassette has a shape greatly different from that of the disk, so that a sufficient cleaning effect cannot be obtained.

Further, in the case of cleaning while supplying water to the brush as in the cleaning device of Japanese Utility Model Publication No. 4-22411, there is a possibility that water containing dirt may be scattered and an object to be cleaned may remain. A part of the object to be cleaned comes into contact with the air only with the water supplied from the nozzle, so that the object to be cleaned may be contaminated by static electricity or the like.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a cleaning device for a disc cassette that is capable of automatically cleaning the disc cassette and has an excellent cleaning effect.
