JPS6150262A - Magnetic disk cartridge - Google Patents

Abstract

PURPOSE:To make a bubble due to air entrainment invisible at the time of sticking and to make appearance of a magnetic disk cartridge excellent by making the material of a reinforced ring non-transparent. CONSTITUTION:The magnetic disk cartridge is composed of a magnetic disk 1 where a hole 26 is made at the center, and a jacket 2 having openings 2b and 2a to contain the magnetic disk rotatably ad to rotate, record and reproduce the magnetic disk from the external, and designed to stick a reinforced ring 5 composed of a non-transparent material at a hole 2b at the center of the magnetic disk. Since the reinforced ring 5 is not transparent, the magnetic disk 1 of the base is constructed to be invisible. Thus, even when a bubble occurs, it is not invisible from the outside and appearance becomes beautiful.

Description

DETAILED DESCRIPTION OF THE INVENTION FIELD OF INDUSTRIAL APPLICATION The present invention relates to a magnetic disk cartridge such as a Frembie disk.

Structure of a conventional example and its problems What is shown in FIG. 1 is a partial perspective view of a conventional magnetic disk cartridge. The jacket to be stored in, 22L, is the record of magnetic disk 1'JJ: l
2b is an opening for rotating the magnetic disk 1, and 3 is a reinforcing ring attached around the hole 1a. When the driving part for rotating this reinforcing ring 3kL magnetic disk 1 enters the hole 18, the hole 1a
This ring is attached for the purpose of completely reinforcing the surrounding area of the ring because it is easy to damage it. However, this reinforcing ring 3 has traditionally been made of transparent material 4)]1), but as shown in Figure 1. Uratsu 1) Ring 3 was attached because it would trap air when it was pasted (if you look at the fishing grounds, you can see a lot of air bubbles 4 and the appearance is very bad) Is it really worth it?'+'1.44 It was quite possible to leave.

OBJECTS OF THE INVENTION It is an object of the present invention to solve the above-mentioned problems and provide a magnetic disk cartridge having a reinforcing ring 11 with a beautiful appearance.

+1111 of the invention; In order to achieve the l-1-like ω1 characteristic of Naruko, the magnetic disk cartridge of the present invention rotatably accommodates a magnetic disk with a hole in the center ('ζ) and a magnetic disk described in 1iif, and It consists of a jacket having an opening through which the magnetic disc rotates and records/reproduces, and a reinforcing ring made of an opaque material is attached to the hole in the center of the magnetic disc. With this structure, even if air bubbles are generated, they will not form from the outside, resulting in a clean appearance.

DESCRIPTION OF EMBODIMENTS FIG. 2 shows a first embodiment of the present invention, in which 1 is a magnetic disk, 2 is a jacket, 2a is an opening for recording and reproduction, and 2b is a magnetic disk.
6 shows the opening of the rotating reservoir, and 6 shows the reinforcing ring. Since the reinforcing ring 5 is opaque, it acts as a trap so that the underlying magnetic disk 1 cannot be seen. Figure 3 shows the second embodiment, and the reinforcing ring 6 has a striped pattern! Similarly to the first embodiment, the underlying magnetic disk 1 is not visible. Moreover, the striped pattern allows for differentiation in appearance. Further, FIG. 4 shows a third embodiment, in which the reinforcing ring 7 is 1
It shows something with a different pattern.

Effects of the Invention As described above, the reinforcing ring of the embodiment of the present invention can be prevented from appearing by making the material of the reinforcing ring opaque or having various patterns, so that no air bubbles caused by air entrainment are visible during pasting. is of very good quality. It is also possible to add interest to the design by adding various patterns.
