Abstract

(57) [Abstract] [Purpose] The object of the present invention is to prevent dust from entering the reading portion of the floppy disk and to always be able to read the contents stored in the reading portion of the floppy disk. It is to provide a dust-proof floppy disk case. According to the invention described in "Claim 1," a dustproof protrusion that can be inserted into a space between a positioning metal fitting mounted on a magnetic floppy disk and a hole for the positioning metal fitting is formed, and Since it also covers the reading part at one end of the floppy disk and has an attachment locking part that is detachably attached to the floppy disk, it prevents dust from entering the reading part of the floppy disk. , You will always be able to accurately read the contents stored in the reading part of the floppy disk.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This invention is a dust-proof floppy disk for preventing the contents stored in a floppy disk used as a recording medium from being erased or the floppy itself being damaged due to the inclusion of dust or the like in the floppy disk. Disc case.

[0002]

[Prior art]

 Conventionally, a floppy disk used as a recording medium can easily read the contents stored in the floppy disk if the floppy disk is loaded into a floppy disk reader.

[0003]

[Problems to be solved by the device]

 However, according to the conventional floppy disk, dust and the like can enter through the space between the positioning metal fitting mounted on the magnetic floppy of the floppy disk and the hole for the positioning metal fitting. There is. A simple shutter is slidably mounted on the floppy disk reading part, but the shutter itself is mounted so that it can be easily moved. There was a problem that dust and the like would directly invade the inside of the floppy disk, scratching the contents stored in the reading area, erasing its contents, or rendering it useless. The present invention has been made to solve the above problems, and its purpose is to prevent dust from entering the reading portion of a floppy disk and to always store the contents stored in the reading portion of the floppy disk. It is to provide a dust-proof floppy disk case that can be read.

[0004]

[Means for Solving the Problems] In order to achieve the above object, the invention described in "Claim 1" has a positioning metal fitting mounted on a magnetic floppy of a floppy disk and a hole for the positioning metal fitting in the central portion. In addition to forming a dustproof protrusion that can be inserted in the space between the floppy disk and the cover, it also covers the reading part at one end of the floppy disk and has an attachment locking part that is detachably attached to the floppy disk. It is characterized by having.

[0005]

[Action]

 According to the invention of "Claim 1" having the above-mentioned structure, a dustproof projection insertable in the space between the positioning metal fitting mounted on the magnetic floppy disk and the hole for the positioning metal fitting is formed. In addition, since it also covers the reading part at one end of the floppy disk and has an attachment locking part that is detachably attached to the floppy disk, dust will not enter the reading part of the floppy disk. It is possible to prevent reading and always read the contents stored in the reading part of the floppy disk.

【Example】

An embodiment of a dustproof floppy disk case according to the present invention will be described below with reference to the drawings. 1 is a perspective view of a floppy disk, FIG. 2 is a perspective view of a dustproof floppy disk case of the present invention, FIG. 3 is a side view of FIG. 1, and FIG. 4 is a state in which the case of the present invention is mounted on a floppy disk. FIG. 5 is an enlarged view of a main part of the dustproof floppy disk case of the present invention. As shown in FIG. 1, the floppy disk 1 has a space 3a formed between a positioning metal fitting 2 mounted on a magnetic floppy disk and a hole 3 for the positioning metal fitting 2. As shown in FIGS. 2 and 3, the dustproof floppy disk case 5 of the present invention is a cylinder that is fitted into a space 3a between the positioning metal fitting 2 of the floppy disk 1 and the hole 3 for the positioning metal fitting 2. Dustproof protrusion 5a made of an elastic member such as a small rubber, that is, a resin system having elasticity, a hard rubber or the like is provided in the central portion. Further, as shown in FIG. 4, the dust-proof floppy disk case 5 covers the shutter 4 that protects the reading portion of the floppy disk 1, and is also a mounting lock that is detachably attached to the floppy disk 1. It has a part 5b. Furthermore, the mounting engagement portion 5b is provided with a hook-shaped mounting portion 5c, after being locked to the floppy disk 1, a cylindrical dust proof projection 5a is formed so as to fit into the space portion 3a ing. As shown in FIG. 5, the cylindrical dustproof projection 5a is formed with a concave portion 7 into which the thick portion of the plate material of the floppy disk 1 can be fitted and a taper portion 8 so that it can be more reliably formed. The dustproof floppy disk case 5 is detachably attached to the floppy disk 1. The recess 7 is shallow and is formed so as to be easily removable.

According to the dustproof floppy disk case 5 of the present embodiment formed as described above, the upper portion of the dustproof floppy disk case 5 is hooked on the upper portion of the floppy disk 1 (the portion of the shutter 4), and then, The dustproof protrusion 5a is fitted into the space 3a of the floppy disk 1 (gap between the rotating parts of the floppy disk 1). Therefore, since the dustproof projection 5a of the dustproof floppy disk case 5 has the concave portion 7, the dustproof projection 5a is securely fitted. When removing the dustproof floppy disk case 5 from the floppy disk 1, lift the dustproof floppy disk case 5 by holding the plate member of the floppy disk 1 to easily attach the dustproof projection 5a to the space of the floppy disk 1. It can be removed from the portion 3a. Further, the attachment locking portion 5b of the dustproof floppy disk case 5 is provided with a hook-shaped attachment portion 5c, and after being locked to the floppy disk 1, it is made of an elastic member such as a cylindrical petit rubber to prevent dust. Since the projection 5a is formed so as to fit into the space 3a and is securely locked to the floppy disk 1, dust is prevented from entering the reading portion of the floppy disk 1 to which the shutter 4 is attached. The contents stored in the reading part of the floppy disk 1 can always be read accurately.

[0008]

[Effect of device]

 As is apparent from the above-mentioned configuration, the invention according to "claim 1" is a dustproof that can be inserted into the space between the positioning metal fitting mounted on the magnetic floppy disk and the hole for the positioning metal fitting. In addition to forming a projection, it also covers the reading part at one end of the floppy disk and has an attachment locking part that is detachably attached to the floppy disk. It is possible to prevent the intruder from entering and to always read the contents stored in the reading part of the floppy disk accurately.
