The present invention relates to the improvement of the structure of a personal computer disk (application number: Utility Model Registration Application No. 91-5919) having a write-protect tab, which is a prior application of the present invention. Therefore, the structure of the jacket for accommodating the tabs is more simply improved to simplify the manufacturing process of the disk and to save material, and to prevent the detachment of the stored tabs.

A general disk write protection device is provided with a recessed groove on one side of a disk jacket. When a disk is to be prevented from being written to protect an existing program or data contained in the disk, a tab is attached to the recessed groove. By shielding the sensor, the sensor detects it in the computer body and prevents writing to the disk of the computer. The use of the write-protect tab requires data to be input to the disk and modification or data input to the disk. When the attached tab is peeled off, the marks or fragments of the adhesive remain, so that the disk looks dirty and there is a problem in that the removal of the tab is cumbersome.

The disc of the original design of the original disc has a sliding tab in the disc jacket, and the write and write protection of the disc can be arbitrarily selected to eliminate the inconvenience of using the removable tab. Since the tab guide piece for guiding the movement back and forth by accommodating the slide tab inside was required to be formed separately, the manufacturing cost of the disc was increased due to the addition of materials and processes for forming the tab guide piece. There was a problem with the tab coming off the jacket.

In addition, Japanese Laid-Open Patent Publication No. 3-2487 discloses a novel configuration of a slide-type write-protect tab for a disc, but this also has a problem of additional burden of materials and processes due to the complicated structure. In order to solve such a conventional problem, the write-protect tab is embedded on the disk without significantly increasing the manufacturing cost of the disk, and at the same time, it is possible to prevent any deviation of the write-protect tab during use. It will be described in detail as follows.

FIG. 2 shows a disk 1 according to the design of the applicant's own application, which is a conventional disk having a center hole 3, a head hole 4, a surface hole 5, and a recessed groove 9 for detecting whether or not to write. In (1), the tab guide concave groove 10 is formed on the side of the write-in detecting concave groove 9, and the disk jacket 2 has the locking groove 12 inside the tab storage chamber 18. The built-in slide tab 11, so that the writing groove 9 for detecting whether to write in accordance with the front and rear movement of the slide tab 11 to open and close the bar, Figure 5 is a disc jacket (2) ) Is an exploded view.

The present invention, in forming the development surface of the disk jacket (2), in the through holes (9a, 10a) immediately above the tab guide through hole (10a) of the folded portion (7a) and the write-through detection hole (9a). By folding and guiding the guide piece 14 having the corresponding recesses 15 and 16, the conventional structure (FIG. 5) in which the slide tab 11 storage chamber is formed is avoided, and as shown in FIG. By removing the guide piece 14, the jacket 2 is configured to be folded by the fold lines 6, 6a, 6b, and 6c, and the thermocompression-bonding portion 13a and the plurality of thermocompression-bonding portions 13 and 13a. A rectangular tab storage chamber 18 is formed between the fold lines 6b of the folded portion 7b, and as shown in FIG. 3, the tab guide through hole 10a and the write-through detection hole 9a are formed. When the disc 1 is formed by folding the disc jacket 2 on the developed view by forming a protrusion 8 having a small notch 8a at the folded end 7a side end of the jacket 2 having the Projection 8 of 7a) When the side is buried by the folding portion 7b, the slide tab 12 accommodated between the thermal compression portion 13 and the folding line 6a of the jacket 2 is grounded at both folding portions 7a and 7b. This is to prevent the phenomenon that the departure to the outside through the boundary line 17.

The present invention constituted as described above pushes the locking grooves 12 of the slide tabs 11 exposed by the tab guide indentation grooves 10 of the disk 1 by hand to slide the slide tabs 11 into the write protection grooves 9. The operation principle is the same as that of the disk 1 of the present invention.

In the present invention, in forming the disk 1 in which the slide tab 11 is embedded, unlike the conventional (FIG. 5), since there is no guide piece 14 for storing the slide tab 11, the front of the disk jacket 2 In constructing the open surface, it is possible to reduce the material of the jacket (2) as well as to minimize the loss of the material (LOSS) at the time of cutting, thereby contributing to the reduction of manufacturing cost, and to simplify the process because the folding process of the guide piece (14) is omitted. On the other hand, since the protrusion 8 of the folded portion 7a buried under the folded portion 7b prevents the slide tab 11 stored in the jacket 2 from escaping to the outside during use, the disc 11 The utility can be doubled during use.

Claims (1)

Center holes 3, 3 ', head holes 4, 4', and surface holes 5, 5 'are symmetrically laid out with the fold line 6 as the center line, and the fold lines 6a, Fold portions 7a, 7b, and 7c having 6b and 6c are formed, and write-through sensing holes 9a on the fold line 6a are centered on the fold line 6 and recesses 9 corresponding thereto. In a conventional disk jacket 2 in which ') is formed opposite; With the fold line 6 as the center line, the tab guide through-hole 10a on the fold line 6a and the corresponding tab guide recess 10 'are formed to face each other, and the protrusions are provided at the side ends of the fold portion 7b. A disk jacket, characterized in that (8) is formed.
