Abstract

PURPOSE:To simply contain and taking out a disk by fitting an upper cover having a pressure part on a containing case and installing in a containing box a clamp spring which fixes the center hole of the disk without contacting said hole when the upper cover is opened and fixed it in such a way that it is pressed by the pressure part and deformed when the upper cover is closed. CONSTITUTION:When the disk 5 is contained in the containing cassette, the upper cover 7 is opened to place the disk 5 on a disk stand 11. Since the inner diameter L of the center hole 17 is larger then the outer diameter l3 of a clamp spring 15a, the disk 5 will not contact the clamp spring 15a. When the upper cover 7 is closed, the spring 15a is pushed by the pressure part 19 to bend in a horizontal direction and abuts on the center hole 17 to fix the disk 5, because the outer diameter l3 of the pressure part 19 is larger than the inner diameter l2 of the spring 15a. Accordingly the disk 5 can be easily contained and taken out.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a storage cassette for storing a recording medium (hereinafter referred to as a disk).

[Prior art]

Conventionally, the fifth storage cassette for storing discs such as optical discs, magneto-optical discs, and conno-9c discs has been used.
The storage cassette 1 shown in Fig. 6 and Fig. 6 will help you get used to it, and the storage cassette 1 stores the disc 5 in the storage case 3 and then closes the top lid 7 to store the disc 5. The configuration is as follows.

The upper lid 7 is pivotally attached to the storage case 3 by a shaft 9, and a thin cylindrical disk stand 11 is provided in the center of the storage case 3, and a clamp having a bent portion 13 at the tip is provided inside the disk stand 11. A spring 15 is provided in a circular shape.

7 and 8 are a plan view and a sectional view of the disk 5, which has a central hole 17 with an inner diameter.

When a disc 5 is stored in or taken out from such a storage cassette 1, it is carried out as shown in FIG.

FIG. 9(a) shows a state in which the disc 5 is not stored in the storage cassette 1. As shown in FIG. 9(b), in order to store the disc 5 in the storage cassette 1, after opening the top cover 7, the disc 5 is placed on the disc stand 11 while the center hole 17 of the disc 5 and the clamp spring 15 are in contact with each other. Push this disk 5 in the direction A until it is placed on top of the disk. When the disk 5 is placed on the disk stand 11, the disk 5 is supported vertically by the disk stand 11 and horizontally by the restoring force of the clamp spring 15.

When taking out the disk 5 from the storage cassette 1, open the top cover 7 as shown in FIG. 15 is bent toward the center to release the contact between the disk 5 and the clamp spring 15, and the disk 5 is taken out.

[Problems with conventional technology]

However, in such a storage cassette 1, as described above, when storing the disc 5 in the storage cassette 1, it is necessary to open the top cover 7 and push the disc 5, and when removing the disc 5, it is necessary to open the top lid 7 and push the disc 5. In addition, it was necessary to open the top cover 7 and press the clamp spring 13, which required many operational steps.

Furthermore, when taking out the disc 5, it is necessary to take out the disc 5 while pressing the clamp spring 13 with your finger.
The operation required to perform two operations at the same time was troublesome.

[Purpose of the invention]

SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a storage cassette in which disks can be easily stored and removed in order to solve the above-mentioned problems.

[Summary of the invention]

In order to achieve the above object, the present invention pivots a top lid having a pressing part to a storage case, and when the top lid is open, it does not come into contact with the center hole of the disk, and when the top lid is closed, the pressing part does not contact the center hole of the disk. By providing the storage case with a clamp spring that deforms when pressed by the upper part and fixes the center hole of the disc, the disc is not restrained by the clamp spring when the top lid is opened, and the disc is not restrained when the top lid is closed. It is fixed by a clamp spring.

[Embodiments of the invention]

An embodiment of the present invention will be described in detail below based on the drawings.

Figures 1, 2, and 3 are a sectional view of the top cover of the storage cassette, a sectional view of the storage case, and a plan view of the storage cassette according to the present embodiment, respectively, and are shown in Figures 5 and 6. Elements that perform the same functions as those of the conventional example are given the same numbers, and explanations of these elements will be omitted.

As shown in FIG. 1, a thin cylindrical pressing portion 19 is provided on the storage case side of the upper lid 7.

As shown in FIGS. 2 and 3, a plurality of clamp springs 15m having a contact portion 21 at the tip are provided in a circular shape in the center of the storage case 3.

The outer diameter t1 of the pressing portion 19, the inner diameter t of the contact portion 21 of the clamp spring 15a = 23% of the outer diameter of the clamp spring 15m
The inner diameter of the center hole 17 of the disk 5 has tz<Al<
There is a relationship As < L. - To store the disc 5 in the storage cassette 1, open the top lid 7 and place the disc 5 on the disc stand 11. At this time, since (the inner diameter L of the center hole 17>the outer diameter t3 of the clamp spring 15&), the disk 5 and the clamp spring 15a are not in contact with each other. Next, close the top lid 7. Outer diameter t of the pressing part 19 of the upper lid 7! is also larger than the inner diameter t2 of the clamp spring 15m, so when the top cover 7 is closed, the clamp spring 15m is pressed by the pressing part 19 and deflects in the horizontal direction, as shown in FIG. 5 comes into contact with the center hole 17 of the disk 5, and the disk 5 is fixed. At this time, the shift lamp spring 15m comes into contact with the center hole 17.
In order to prevent the expansion of the pressing part 19 and push the pressing part 19 toward the center, the pressing part 19 having spring properties is deformed toward the center,
The center hole 17 will not be damaged or deformed by the clamp spring 15aK.

In order to take out the disc 5 from the storage cassette 1, the upper lid 7 can be opened. When the top cover 7 is opened, the clamp spring 15m returns to the state shown in FIG. You can get it out.

Therefore, when storing the disc 5, all you have to do is open the top cover 7 and place the disc 5 on the disc stand 11 (the conventional operation of pushing the disc 5 in is omitted).

Also, when taking out the disc 5, all you have to do is open the top cover 7 (the conventional operation of pushing in the clamp spring 15 can be omitted, and the two operations of pushing in the clamp spring and taking out the disc 5) are now possible. They do not have to be done at the same time.

Note that the shape of the pressing part 19 and the shape of the clamp spring 15a are not limited to the shapes shown in this embodiment. Any shape may be used as long as it bends in the horizontal direction. Further, the number of clamp springs 151 is not limited to the number shown in this embodiment.

〔Effect of the invention〕

As described above in detail, according to the present invention, it is possible to easily store and take out a disc.
