It receives and supports the side, and the extruded portion of the cleaning member 16 enters the head window 5 and presses and contacts in the radial direction of the disk surface of the disk 3.

Then, when the opening / closing lid 10 is closed, as shown in FIG. 1, the opening / closing lid 10 is automatically closed and locked by the lock lever 35 as shown in FIG.
The disc cartridge D is pressed onto the upper surface 9 by the pressing pin 32 as shown in FIG. Further, the rotary shaft portion 23 on the lid 10 side enters into the drive shaft insertion window 4 on the upper surface side of the disc cartridge D, and the central shaft 26 is fitted into the central hole 13b of the hub receiver 13 to receive the hub 2 from the hub. It is connected to the hub 2 by pressing it horizontally against the body 13. Further, the pressing pad 29 enters into the head window 5 on the upper surface side of the disk cartridge D and presses and contacts the disk surface of the disk 3 in the radial direction, and presses the lower surface of the disk 3 to the cleaning member 16.

Thus, as shown in FIG. 12, when the fingertip is inserted into the concave portion 24a of the manual handle 24 and the manual handle 24 is horizontally rotated around the rotary shaft portion 23 on the opening / closing lid 10, the rotary shaft portion 23 is moved. When it rotates and its eccentric shaft 27 reaches the drive hole 7 of the hub 2, the force is applied to the drive hole 7 by a spring 28 to rotate the disk 3 as shown in FIG. The dirt attached to the surface of the disk 3 as the disk 3 rotates is wiped off by the cleaning member 16.
At this time, since the pressing pad 29 can be tilted in the radial direction, even if the disk 3 rotates in a swell, the pressing pad 29 comes into pressure contact along the swell, so that the unwiped portion of dirt is not left.

[0026]

According to the disk cleaner of the present invention, since the pressing pad 29 is mounted so as to be tiltable in the radial direction with respect to the disk 3 and always in elastic contact with the spring member 30, the pressing pad 29 is always contacted with the disk 3. The contact can be made stably with a constant surface pressure, and the pressure contact can be made by following the undulating rotation of the disk 3, so that the cleaning member 16 can wipe it evenly without uneven wiping or unwiping.
