Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an envelope for containing and protecting a floppy disk when it is not in use.

Floppy disks, which have a structure in which a flexible magnetic disk is housed inside a jacket with a non-woven fabric pasted on the inside, have been widely used in recent years as microcontrollers have become popular as external storage devices that can be handled relatively easily. There is.

However, considering the structure of the floppy disk, the jacket has a drive shaft insertion window,
Openings such as a magnetic head insertion window and an index hole window are formed, and the magnetic disk stored in the magnetic disk is exposed through these openings, and in particular, the signal recording portion of the magnetic disk is exposed through the magnetic head insertion window. is exposed. Therefore, when the floppy disk is not in use, the exposed portion of the magnetic disk mentioned above may be damaged, or dust or dirt may leak out from the opening.
Conventionally, the jacket is generally housed in an envelope as shown in FIG. 1 to prevent dust and the like from entering the jacket.

This envelope is made by combining a long piece 1 and a short piece 2 to form a pocket part 3 that accommodates a floppy disk 4. By inserting the floppy disk 4 in the direction shown in the figure, the opening of the jacket 5 is opened. The exposed portion of the magnetic disk 6 at this point is covered and protected by an envelope.

However, as mentioned above, computers containing microcontrollers are being installed everywhere these days, and for this reason, it is necessary to transport floppy disks, which are external storage devices, and play them at another location so that the recorded data can be stored. In many cases, the information that is available is used.

As floppy disks are often moved and transported in this way, they will naturally be taken outside from the environmentally controlled room where the computer is installed, and exposed to dusty environments. It will be. Therefore, when taking a floppy disk out of the operation room, it is natural to put the floppy disk in an envelope, but with the conventional envelope shown in Figure 1, the floppy disk easily slips out of the envelope and accidentally turns the envelope downward. In such a case, the floppy disk will easily fall to the floor or the like, and dust will enter the jacket through the opening, causing problems with the recording and reproducing functions.

Therefore, the purpose of the present invention is to provide an envelope that can adequately protect floppy disks, which are being used in a wide range of areas, and to protect the non-disk part of the floppy disk contained in the envelope. This is to prevent it from accidentally falling from the envelope.

The present invention will be explained in detail below with reference to embodiments of the drawings.

In a floppy disk, the magnetic disk can rotate freely within the jacket, but since all four sides of the jacket are sealed, it can only move up, down, left and right within a slight margin for rotation. Only. Therefore, a floppy disk in which a circular magnetic disk is enclosed within a rectangular jacket has portions at its four corners where no magnetic disk is present.

Utilizing such structural features of the floppy disk, as shown in FIGS. 2 and 3, the long piece 1
Clamps 14, 14 are provided at positions sufficiently apart from the center of the bottom of the bag-shaped portion 13 which accommodates the floppy disk formed by the floppy disk 1 and the short piece 12. Although it is preferable to have two symmetrical positions as in this embodiment, there is no particular limitation. Clamping body 1
4 and 14 have a U-shaped cross section as shown in Fig. 3, and both ends thereof are folded inward, and the gap therebetween is set to be slightly smaller than the thickness of the portion of the floppy disk where no disk exists. . Thin steel or plastic can be used as the material, and it can be attached to the bottom of the envelope by pasting or bending. When two clamping bodies are attached as in this embodiment, if the clamping force obtained by the two clamping bodies is made slightly larger than the weight of the floppy disk, the floppy disk 4 can be accommodated in the bag-shaped portion 13. Furthermore, by inserting the floppy disk 4 into the gap between the clamping bodies 14, 14, the floppy disk 4 will not fall even if the envelope is accidentally turned upside down.

In this way, by making the total clamping force obtained by the attached clamping bodies slightly larger than the weight of the floppy disk, it is possible to prevent the floppy disk from falling unnecessarily. Also,
This clamping force is set to the minimum necessary to prevent falling, so there is no need for special force or operation to insert or remove the floppy disk from a normal envelope, and it is as simple as the conventional one. This allows for easy handling.

Furthermore, since the clamping body 14 clamps the corners of the floppy disk 4 where no disk is present, there is no adverse effect on the disk itself.

As described above, according to the present invention, the floppy disk can be prevented from accidentally falling from the envelope, and the floppy disk can be sufficiently protected when not in use.

Claims (1)

[Scope of utility model registration request] A clamping body having a clamping force slightly greater than the own weight of the floppy disk is provided at the bottom of the bag-shaped portion that accommodates the floppy disk, and the mounting position of this clamping body corresponds to the portion of the floppy disk where the disk does not exist. A protective envelope for the floppy disc.
