材86を金属板72の外周面に被せて構成されている。By the way, there are various types of scrub cleaning rotary brushes 70 in the related art. As shown in FIG. 9, the scrub cleaning rotary brush 70 includes a disc-shaped metal plate 72, a scrub sponge material (spongy elastic material) 76 attached to both surfaces of the metal plate 72 via an adhesive 74, It consists of 76. Also,
The scrub cleaning rotary brush 78 shown in FIG. 10 is formed by joining small pieces 80, 80 of a scrubbing sponge material 76 to a metal plate 72 and sewing them. The scrub cleaning rotary brush 82 shown in FIG. 11 is configured by covering a scrubbing sponge material 86 having projections 84, 84.

溶出物が溶出し、磁気ディスクの二次汚染をする不具合
がある。However, such a conventional scrub cleaning rotary brush has the following disadvantages. For example, as shown in FIGS. 9 and 10, a scrubbing sponge material 76 bonded or sewn with an adhesive 74 has a strong pressing force at the time of scrubbing, so that a large frictional force with the surface of the magnetic disk 20 is generated. As a result, the scrubbing sponge material 76 frequently falls off. For this reason, when continuous cleaning is continued in the life test, it becomes almost unusable in about 2 to 3 hours. In addition, the eluate elutes from the adhesive together with such a detachment defect and the like, and there is a problem that secondary contamination of the magnetic disk occurs.

を起こす不具合がある。Further, as shown in FIG. 11, the structure in which the sponge material for scrubbing 86 having projections is covered on the outer periphery of the metal plate 72 has a sufficient cleaning effect because the fixing and holding of the sponge material for scrubbing 86 are unstable. There is a defect that cannot be exhibited. Further, in the rotary brush for scrub cleaning disclosed in Japanese Utility Model Application Laid-Open No. 61-158948, the cleaning liquid is accumulated between the sponge material for scrubbing and the holes, and this cleaning liquid has a problem that secondary contamination of the magnetic disk may occur again.

However, in the conventional scrub cleaning rotary brush, there is a problem that the attachment of the sponge material for the scrub is complicated, and that the sponge material is easily contaminated during the attachment work.

成形することを特徴とする。In order to achieve the above object, the present invention comprises a rotating plate and an elastic material covering both surfaces of the rotating plate, and is inserted between a plate to be cleaned and a plate to be cleaned so as to cover the outer surface of the elastic material. In a rotary brush for scrub cleaning in which the cleaning plate surface is cleaned by sliding contact with the cleaning plate surface, a plurality of holes are formed in the rotary plate surface, and the elastic material is formed of a sponge-like resin. It is characterized in that both sides of the rotating plate are covered and each hole of the rotating plate is filled and integrally formed.

る。According to the scrub cleaning rotary brush according to the present invention, a plurality of holes penetrating both surfaces of the rotary plate are formed, the elastic material is made of a sponge-like resin, and covers the both surfaces of the rotary plate when it is melted, and the rotary plate Is filled in the hole. Therefore, since it is integrally molded and fixed to the metal plate covering the entire metal plate,
It does not require an adhesive or the like for fixing the elastic material to the metal, and does not cause secondary contamination or the like due to elution of the adhesive or the like. Further, since the elastic material is filled in the plurality of holes, when the elastic material is twisted, the elastic material is prevented from being displaced from the metal plate, the adhesion to the metal plate is improved, and the elastic material is prevented from falling off.

詳しい説明は省略する。Hereinafter, preferred embodiments of a scrub cleaning rotary brush according to the present invention will be described in detail with reference to the accompanying drawings. FIG. 1 is a perspective view according to the present invention. The scrub cleaning rotary brush 40 shown in FIG. 1 is a cleaning device 10 shown in FIGS. 8 (A) and (B).
The magnetic disk 20 can be washed. Therefore, a detailed description of the cleaning device 10 is omitted.

42中央部付近が外周部付近より多く形成されている。The scrub cleaning rotary brush 40 includes a metal plate (rotary plate) 42 serving as a main body, and a scrubbing sponge material 44 covering the metal plate 42. The metal plate 42 is made of a SUS plate, and has a mounting hole 46 formed in the center thereof. The mounting shaft 28 of the rotating arm 26 of the cleaning device 10 is inserted into the mounting hole 46. In addition, a plurality of through holes 4 are formed on the surface of the metal plate 42 covered with the
8, 48 ... (diameter of about 6 to 8φ) are formed, and the opening ratio (the ratio of the total area of the plurality of holes formed to the entire area of the metal plate) is 15% or more. The amount of holes is a metal plate
42 The vicinity of the center is formed more than the vicinity of the outer periphery.

, And then reacted to be integrally molded. As the resin for the scrubbing sponge material 44, besides using polyvinyl formal, other polyvinyl acetal resins can be used. It should be noted that an appropriate amount of a pore agent can be added to these resins.

提供することができる。According to the scrub cleaning rotary brush configured as described above, the scrub cleaning rotary brush 40 is attached to the cleaning device 10 and the scrub (rubbing) is applied to the magnetic disks 20, 20,... With a pressing force of about 100 to 200 g / cm 2. Contact) and the magnetic disks 20, 20 ...
Cleaning. In this case, each side portion of the scrubbing sponge material 44 covering the metal plate 42 is a through hole 48 of the metal plate 42,
48 and the outer peripheral edge 42B of the metal plate 42, the bonding strength to the metal plate 42 is improved.
Further, since the scrubbing sponge member 44 is formed integrally and does not use an adhesive or the like, there is no secondary contamination such as elution of the adhesive component. Further, the thickness of the scrubbing sponge member 44 can be made thinner than the conventional manufacturing method because no adhesive or the like is used.
That is, conventionally, the thickness of the rotating brush could not be reduced to 16 mm or less. However, according to the scrub cleaning rotary brush 40 of the present invention, the thickness can be reduced to 12 mm or less. Therefore, since it is not necessary to increase the width of the plurality of scrub cleaning rotary brushes 40, 40 ..., the cleaning device 10 itself can be downsized, and the cleaning device 10 with a small space can be provided.

を多くすることが望ましい。FIG. 4 is a characteristic curve diagram showing the opening ratio of the through-holes 48 of the metal plate 42 and the ratio of the missing parts of the scrubbing sponge material 44. This is because the pressing force of the scrub cleaning rotary brush 40 against the magnetic disk 20 is set to 280 g / cm 2 and the number of rotations is reduced.
At 300 rpm, sponge material for scrubbing at predetermined time
This shows the rate at which 44 dropped out. As can be seen from this result, when the opening ratio of the metal plate 42 is 15% or more, the dropout rate of the scrubbing sponge material 44 sharply decreases. Therefore, the opening ratio of the metal plate 42 is preferably 15% or more. Further, since a larger load is applied to the scrub (sliding contact) with the magnetic disk 20 at the inner peripheral portion than at the outer peripheral portion of the rotary brush 40 for scrub cleaning, the through-hole 48 is formed in the inner peripheral portion.
It is desirable to increase the number.

Are formed on the scrub cleaning rotary brush 52, so that a flat scrub sponge material is formed. Compared to the cleaning water, the fluidity of the cleaning water is improved, and the pressing force of the tip of the projection 66 on the cleaning surface can be increased.
The cleaning effect also increases.

Further, a tapered counterbore 60 is formed around the through hole 58 to increase the volume occupied by the scrubbing sponge member 54 and prevent the projection 66 from falling off. Also, protrusion
The base 66A of 66, 66 ... is formed in a truncated cone and has a diameter of about 120% or more than the tip 66B, so that the protrusion 66 is prevented from being lost from the root.
