Then, the disc substrate 17 rotates, and the dust and the like adhering to the surface of the disc substrate 17 is wiped off by the adhesive roller 21.

[0004]

However, in the above-mentioned conventional dust wiping apparatus, since the wiping pressure is constant, fine adjustment cannot be performed when the value set at the beginning cannot be removed.

Further, since the adhesive roller rotates a number of times to wipe the disk, the adhesive roller rubs the surface of the disk with dust adhering, which may scratch the surface of the disk.

Furthermore, since the pair of adhesive rollers are fixed in the vertical direction, it is difficult to replace the disk.

The present invention has been made in view of the above-mentioned conventional circumstances, and therefore, the object of the present invention is to provide a novel cleaning of an information recording medium capable of solving the above-mentioned problems inherent in the prior art. To provide a device.

Next, the operation of the mechanism according to the present invention shown in FIGS. 1, 2 and 3 will be described.

First, when the information recording medium 17 such as a disk is replaced, the cylinder 5 is operated and the piston rod 9 pushes out the connecting portion of the roller opening / closing mechanism 7 with the horizontal shaft 8 to open the roller opening / closing mechanism 7. This is the state (broken line in FIG. 1). That is, the first lever 7a is rotated clockwise about the horizontal shaft 8, and the second lever 7b is rotated counterclockwise about the horizontal shaft 8, and therefore,
The first arm 7c is rotated clockwise about the first shaft 7e, and the second arm 7d is rotated counterclockwise about the second shaft 7f. The second rollers 10a and 10b are the information recording medium 17 respectively.
Away from contact with the upper and lower surfaces of the and are opened as indicated by the dashed lines in FIG. At that time, the pulleys 14a and 14b are connected to the connecting rod 27.
In order to move in synchronization with the cylinder 5 and the piston rod 9 as shown by the broken line in FIG.
The a and 11b are in a slackened state, and when the roller opening / closing mechanism 7 is in an open state, no excessive force is applied to the dustless cloths 11a and 11b.

After the information recording medium 17 is set, the piston rod 9 of the cylinder 5 pulls the connecting portion with the horizontal shaft 8 of the roller opening / closing mechanism 7 so that each element of the roller opening / closing mechanism 7 operates in reverse to the opening operation. Closed (rollers 10a, 1
0b is in contact with both upper and lower surfaces of the information recording medium 17). At that time, the pulleys 14a and 14b are attached to the dust-free cloth 11
Move to a position where tension is applied to a and 11b.

Next, the take-up reels 15a and 15b are rotated by a motor or the like to remove dust-free cloths 11a and 11b.
From the feed reels 12a, 12b to the feed pulley 13a,
It is supplied to the rollers 10a and 10b via 13b, respectively, and thereafter, is guided by the take-up pulleys 14a and 14b and taken up by the take-up reels 15a and 15b. In that case,

0b is in contact with the dust-free cloth 11, such as rotatable rubber rollers 10a and 10b at the portion where dust or the like is wiped off.
It serves to absorb the feeding of a and 11b, the deformation of the information recording medium 17 and the like by elasticity, clean the area, and prevent the information recording medium 17 from being scratched.

Both sides of the information recording medium 17 are simultaneously cleaned by reciprocating the machine board 2 on which all of the above functional parts are mounted in the cylinder 3 in the radial direction of the information recording medium 17.

Further, in the present invention, the information recording medium 17 is also provided.
In order to adjust the pressing force of the rollers 10a, 10b against the roller, that is, the wiping pressure, the pressure fine adjustment means 6 for finely moving the precision table 4 to which the cylinder 5 is attached is operated.
That is, when the precision table 4 is moved in the direction of the recording medium 17 by operating the pressure fine adjustment means 6, the recording medium 1 by the rollers 10a and 10b of the roller opening / closing mechanism 7 is moved.
The force for sandwiching 7, that is, the dust wiping pressure becomes weak, and conversely, by moving the precision table 4 in the direction opposite to the recording medium 17, the dust wiping pressure becomes strong.

[0025]

As described above, according to the present invention,
Since the roller opening / closing mechanism driven by the cylinder is configured to wipe off the dust such as sandwiching the information recording medium, simultaneous cleaning of both sides of the recording medium can be realized, and dust can be removed by simply moving the cylinder position on the precision table. It is possible to obtain the effect that the wiping pressure can be adjusted.

Further, since the tape-shaped dust-free cloth is sequentially fed by the rubber-like roller to wipe off dust and the like, it is possible to cope with a slight deformation of the disk, and the cloth without dust is always adhered. The effect that the dust etc. can be wiped off in the state is obtained.
