Description

[Detailed description of the invention] [Industrial application field] This invention is a disk that removes dirt from a rotatably built-in cartridge case or a digital audio disk (product name: compact disk). Regarding cleaners.

[Conventional technology]

For example, the present applicant has previously proposed a disk cleaner that can easily and quickly remove fingerprints and hand marks from dirt attached to the disks in the disk cartridge (for example, Japanese Patent Application No. 1983 -286149 and Jitsugan No. 14832).
There, a disk cartridge is placed and fixed on the mounting surface of the main body case which has a cartridge mounting surface, and the inside of the disk cartridge is fixed by rotating a manual handle attached to the lid that covers the mounting surface. As the disk is rotated, the cleaning member is brought into pressure contact with the recording surface of the disk facing the head insertion window of the disk cartridge to wipe off dirt on the recording surface.

[Problem that the invention attempts to solve]

However, the above-mentioned manual handle is formed in a lever shape or a disc shape, and in the case of the lever shape, the base end in the longitudinal direction has a rotating shaft part, and in the case of the disc shape, the central part has a rotation shaft part on the top surface of the lid. It is attached so that it can be rotated horizontally, but when it is rotated, the eccentric part of the manual handle that is off the axis of the rotation center is strongly pressed against the top surface of the lid with finger pressure. As a result, I realized that the manual handle tends to wobble due to the uneven load caused by finger pressure, making its rotation unstable and potentially damaging the disc.

The purpose of this invention is to solve this problem and enable stable rotation of the manual handle on the lid.

[Means for solving problems]

In order to achieve the above object, this invention includes a main body case 8 having a mounting surface 9 on which the disk 3 is mounted, and a lid 10 covering the upper part of the mounting surface 9, as shown in FIG. A disk cleaner is provided in which a manual handle 24 for rotating the disk 3 is supported on the top surface of the lid 10 so as to be horizontally rotatable around the rotation shaft portion 23. Spring 3 mounted on shaft 23
1, it is assumed that the lid 10 is always drawn toward the upper surface side.

Here, the disk 3 refers to a cartridge case 1 having a drive shaft insertion window 4 and a head insertion window 5.
In addition to the case-enclosed disk 3 that is rotatably housed inside, it also includes digital audio disks or optical disks that are not housed in a case.

When applied to a digital audio disk or an optical disk, it is placed directly on the mounting surface 9 and cleaned. Also,
In this case, the disk is placed and fixed on the placement surface 9,
The cleaning member is rotated onto this disk surface using a manual handle 24.

The cleaning member 16 may be in the form of a cartridge in which the cleaning member 16 is made into a tape and can be drawn out into the cartridge case 18, or may be in the form of a pad made of raised urethane and sponge. Good too.

It is preferable that a ball 28 be interposed between the opposing surfaces of the manual handle 24 and the top surface of the lid 10 in order to make the rotation of the manual handle 24 smoother.
In addition to the ball 28, ribs may be provided on the handle 24 side or the lid 10 side to reduce contact friction between the opposing surfaces.

[Effect]

In such a case, the spring 31 will release the manual handle 2.
4 is absorbed, and the manual handle 24 can be rotated very stably and smoothly without shaking in the vertical direction.

[Effect of idea]

Therefore, according to this invention, the manual handle 24 for rotating the disk 3 or the cleaning member 16 can be smoothly and stably moved by a simple method of constantly pulling the manual handle 24 toward the top surface of the lid 10 using the spring 31. The disk 3 can be rotated and cleaned stably without damaging the disk 3.
