JPH0316075A - Dust removing device for disk - Google Patents

Abstract

PURPOSE:To remove dust on medium by bending a linear of a medium magnetic recording read/write window part. CONSTITUTION:A liner 2 in which a lancing part is provided so as to have a window 4 in the part opposed to an opening hole part for recording of a jacket 1 is provided in the jacket 1. Also, the lancing part is allowed to abut on a recording medium in the jacket 1. That is, when a notch of the window 4 parts of the liner 2 is bent, springiness of a bend part of the liner 2 and a swell of its part are generated in the liner 2, and it comes into contact positively with medium 3. In such a way, dust on the media 3 is wiped off by the liner 2, thus, removing dust.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a disk dust removal device that is used for floppy disks in general, including 3.5-inch floppy disks and 2-inch floppy disks, and disk-shaped storage devices in general.

BACKGROUND OF THE INVENTION A conventional disk dust removal device of this type, using a 3.6-inch floppy disk as an example, is equipped with a jacket, a liner, a thin resin leaf spring, and a disk-shaped medium, and removes dust from the medium. By pushing the liner against the leaf spring, it is designed to attract dirt into the liner and remove it. The encased leaf spring uses the ribs on the jacket to press the liner against the media.

Figure 4 is a plan view of a conventional 3.5-inch floppy disk.9 In the figure, 2 is the liner, 4 is the leaf spring, and 6
indicates a jacket reply.

FIG. 6 shows a cross section taken along line A-A' in FIG. 4, including the media cup and jacket. In the figure, 1 is a jacket, 2 is a liner, 3 is a media, 4 is a leaf spring, and 6 is a lip.

Problems to be Solved by the Invention However, the conventional disk dust removal device described above has the following problems:
It is costly because lip processing is required on the leaf spring and the jacket that supports the leaf spring.

The present invention is intended to solve these conventional problems, and aims to provide an excellent disk dust removal device that does not require lip processing on the leaf spring or jacket.

Means for Solving the Problems In order to achieve the above-mentioned object, the present invention enables the conventional dust removal function to be realized using only a jacket, liner, and media.

Function The present invention has the above-described structure, and by bending part of the liner of the media magnetic recording/reading/writing window, the bent portion has spring properties, and functions as the conventional plate spring and the ribs of the jacket. In addition, you can press the media against it and remove dust on the media.

Embodiment FIG. 1 shows the structure of an embodiment of the present invention. In FIG. 1, 3 and 2 are liners, which are mounted by sandwiching the media 3. They are covered by one jacket. 4 is a window for reading records on the media. These discs are covered by the same jacket and become one floppy disk.

Next, the operation of the above embodiment will be explained. In the above embodiment, FIG. As shown in FIG. 3, by cutting the liner 2 through the notches h and bt at the window 4 portion as shown in the figure, the liner has a spring property at the bending portion of the liner and a rise in that portion, and the media 3 Actively contact. Then, when the media rotates, the dust on the media is wiped off by the liner, and the dust can be removed.

As described above, the above embodiment has the effect that dust can be removed using the liner alone, without using a leaf spring to press the liner against the media as in the conventional system.

Effects of the Invention As is clear from the above embodiments, the present invention is capable of removing dust from media simply by changing the shape of the liner, and does not require the use of leaf springs as in the conventional method. has advantages.
