As shown in FIG. 1, one of the two disks 1 and 2 is provided with a bearing 3 at its center for free rotation, and the other disk 2 is provided with a bearing 3 at its center. A rotation transmission hole 4 such as a square hole is provided, and rotation is transmitted by fitting this hole 4 into a rotation transmission shaft such as a square shaft.

These two disks 1 and 2 are integrated by being attached to a hold arm 5 at two points on their periphery.

A plurality of support grooves 6 are formed in this hold arm 5 toward the center side, and the peripheral edge of one information recording disk A is inserted into each of these support grooves 6, and the information recording disk A is inserted into each of the support grooves 6. It is supported at two places around its periphery.

A boss 7 is attached to the center of each disk 1, 2, into which a slide hole 9 of a lock arm 8 is slidably inserted, and a pin 10 of the lock arm 8 is inserted into a guide hole 11 of the disks 1, 2. It is slidably inserted into the

This guide hole 11 has a radial shape 11a from the middle.
and an arcuate portion 11b relative to the center.

Further, a support groove 12 for supporting the peripheral edge of the information recording disk A is formed on the inner peripheral surface side of the lock arm 8, and an elastic groove 1 is formed on the outside of this support groove 12.
3, the support groove 12 is given elasticity toward the outside.

Further, a spring 14 is installed between the lock arm 8 and the disks 1 and 2, and urges the support groove 12 of the lock arm 8 toward the center.

To mount the information recording disk A on the support device B for cleaning the information recording disk A, a setting stand C shown in FIG. 1 is used.

This setting stand C is provided with a plurality of insertion grooves 15 into which the information recording disks A are inserted, and a partition wall 16 between each insertion groove 15, as well as for positioning when the cleaning support device B is placed thereon. Claw 1
7 is formed.

When the cleaning support device B is placed on this setting stand C, the cleaning holding device B is moved between the support groove 6 and the insertion hole 15 by the positioning claw 17.
The left and right positions of the images are now aligned.

Therefore, the slide hole 9 and the pin 10 are slid against the radial portion 11a of the boss 7 and the guide hole 11 against the bias of the spring 14, and the lock arm 8 is moved so that the support groove 12 is separated from the center. move it.

Next, this lock arm 8 is retracted from above between the hold arms 5 to the side by sliding the circular arc portion 11b of the guide hole 11 using the pin 10.

Thereafter, one information recording disk A is inserted into each of the insertion grooves 15 and the support grooves 6 from the space into which the lock arm 8 above the hold arm 5 has retreated.

Then, since the insertion groove 5 supports the information recording disk A with its long surface, the information recording disk A is supported by the support groove 6 in a vertically standing state.
