In this state, the small protrusion 37 of the head 32 is fitted into the small groove 38 near the lock port 22.

The key means 20 is, as shown in FIG. 2, a leg portion 39 which is inserted into the housing 18 through the unlocking port 23.
And a head 40 at the tail end of the leg. The leg portion 39 is formed into a substantially L-shaped cross section, and when inserted through the unlocking port 23,
A first unlocking piece 41 that enters along the partition wall 21 and reaches the first locked portion 29, and a first unlocking piece 41 that enters along the inner surface of the tongue piece 18b and reaches the second locked portion 30. And the second unlocking piece 42.

According to the protective case 1 having the above-described structure, the center of the disk 2 is supported by the support portion 7a of the case body 4 through the claw piece 8a or by the support portion 7b of the lid 5 through the claw piece 8b. When the case body 4 is covered with the lid body 5 with the hole 2a held, the disc 2 is housed in the protective case 1 as shown in FIG. At this time, the tongue piece 1 is attached to the box-shaped portion 18a.
Since the housing 18 of the locking device 17 is formed by inserting 8b, the box-shaped part 18a and the tongue piece 18b are locked so that the box-shaped part 18a and the tongue piece 18b are mutually fixed when the locking means 19 is inserted. .

Therefore, the protective case 1 accommodating the disk 2 is inserted into the outer case 43 as shown in FIG. 3 and is displayed by standing up on a display shelf of a store or the like. The outer case 4 is formed in a box shape with one end open, and the protective case 1 is inserted into the outer case 4 with the housing 18 facing the insertion direction.
The support pieces 44, 44 for supporting the vicinity of the shoulders 9, 9 of the protective case 1 when inserted into the inside are fixedly provided inside, and the hinge portion 6 of the inserted and supported protective case 1 is provided. The vicinity of the side edge on the side is projected from the opening of the outer case 4 so that the outer case 4 visually confirms that the protective case 1 is stored. In the outer case 4, a transparent sheet 45 is superposed on the outer surface and is fixed by welding 46 or the like, and a jacket sheet for displaying the recorded contents of the disc 2 is inserted inside the transparent sheet 45 in a removable manner. There is.

By the way, the customer visiting the store is in the outer case 4
3 can be picked up by hand and the protective case 1 can be taken out freely, but the protective case 1 is locked by the locking means 19
7 is locked, so disk 2 is a protective case 1
Can not be taken out from. Protective case 1 as described above
Is made of a relatively soft and flexible synthetic resin material so that the disc 2 is not damaged. Therefore, for example, if the entire shape of the protective case 1 is formed in a rectangular shape and angular corner portions are provided on both shoulders located on both sides of the locking device 17, the case main body 4 is provided at the corner portion away from the locking device 17. It is possible to illegally open the mating surface of the lid 5 and spread it, and pull out the disc 2 from the gap to steal. On the other hand, according to the present invention, first of all, the shoulder corners of the protective case 1 are not provided on both shoulders, and the arcuate arc portions 10a and 10b are provided on both shoulders 9 and 9. Since it is formed, it is difficult to illegally open it. Secondly, in addition to the circular arc shape, the reinforcing ribs 1 are formed on the circular arc portions 10a and 10b.
Since the rigid portions 14a and 14b composed of 3a and 13b are formed, it is almost impossible to form a gap by punching. Further, thirdly, as shown in FIG. 2 (B), the columnar piece 15 is nested from the other supporting portion 7b to the claw piece 8a of the one supporting portion 7a that holds the center hole 2a of the disk 2. Since the columnar piece 15 is not moved until it is pulled out from the claw piece 8a, the central hole 2 of the disc 2 is not moved.
It is not possible to separate a from the columnar piece 15, and as a result, even if there is a gap between the case body 4 and the lid body 5, it is impossible to remove the disc 2. The columnar piece 1
5 also has an effect that the disk 2 can be prevented from freely moving inside the protective case 1 even if the center hole 2a of the disk 2 is separated from the claw piece 8a or 8b.

The locking action of the locking device 18 is shown in FIG. 4 (A-1) and (A-2) show the locking start state, and inside the housing 18 formed by fitting the tongue piece 18b into the box-shaped portion 18a,
When the locking pieces 27b, 27b are superposed on the locking pieces 27a, 27a and the locking means 19 is inserted from the locking port 22 in the direction of the arrow shown in the figure, the locking means 19 becomes the step groove 3
3 is inserted while being guided by the stepped rail 28, and locking pieces 27a, 27a and locking pieces 27b, 2
7b is clamped in the overlapped state. Locking means 19
4 is completely inserted, FIG. 4 (A-3) and (A-
As shown in 4), the first locking claw 35 is locked to the first locked portion 29 and the second locking claw 36 is locked to the second locked portion 30. The locking means 19 is fixed so that it cannot be pulled out. At this time, the head 32 of the locking means 19
Is fitted into the locking port 22, and the small projection 37 of the head 32 is fitted into the small groove 38 near the locking port 22. In this way, the locking means 19 includes the first locking claw 35 and the first locked portion 2
9. Since the second locking claw 36 and the second locked portion 30 are fixed at two locations such that they cannot be pulled out, it is extremely difficult for a visitor to illegally pull out the locking means 19. In this regard, since the protective case 1 is made of a relatively soft and flexible synthetic resin, it is possible to pierce a thumbtack or other needle having a pointed tip, and thereby the locking claw is locked. According to the present invention, at least the first locking claw 35 and the first locked portion 29 are separated from the partition wall 21 inside the housing 18, although it is expected that they will be separated from each other.
Since it is provided in the portion of the first locking claw 3 even if a needle is pierced into the tongue piece 18b,
It is impossible to disengage 5 from the first locked portion 29.

On the other hand, the unlocking action of the locking device 18 is shown in FIG.
As shown in (A-5) and (A-6), the unlocking port 2
When the leg portion 39 of the key means 20 is inserted from the position 3 as shown by the arrow in the figure, the first unlocking piece 41 enters along the partition wall 21 and reaches the first locked portion 29. The locking claw 35 is elastically deformed and retracted from the first locked portion 29. At the same time, the second unlocking piece 42 enters along the inner surface of the tongue piece 18b and reaches the second locked portion 30, whereby the second locking claw 36 is elastically deformed and the second locked portion is locked. Part 30
Retreat from. When the key means 20 is further pushed in, the tip of the leg portion 39 (the first unlocking piece 41 and the second unlocking piece 42).
(The tip of the lock means 19) abuts on the claw ends of the first locking claw 35 and the second locking claw 30 of the locking means 19 and pushes the locking means 19 out of the locking port 22, so that the head 32 of the locking means 19 will be used thereafter. It suffices to grasp and pull out from the housing 18.

As described above, when the protective case 1 containing the disc 2 is displayed in a store, the locking can be completed by one-touch operation of inserting the locking means 19 into the housing 18 from the locking opening 22, and the workability is improved. Very good. When the disk 2 is to be rented or sold to a customer, the key means 20 is inserted into the housing 18 through the unlocking port 23 and the locking means 19 is pulled out to complete unlocking with almost one touch, and the disk can be opened and closed. It suffices if the disk 2 is handed over to the customer together with the protective case, and the workability is also very good.
