BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a disk storage case for storing an optical disk such as an LD, a CD and a CDV.

[0002]

2. Description of the Related Art Conventionally, as a disk storage case for storing an optical disk such as an LD, a CD, and a CDV,
One in which a lid is provided to be freely opened and closed with respect to a case body is used.

FIG. 12 shows an example of such a disk storage case, which comprises a case body 1 and a lid 2.
Projections 3 are provided on both sides of the rear end of the case body 1. The engagement holes 4 of the cover 2 are fitted into the projections 3 so that the cover 2 can be opened and closed with respect to the case body 1. You. In the vicinity of each projection 3, a locking projection 5 is provided.
The lid 2 is locked to the case body 1 by fitting the locking recess 6 of the lid 2 into the locking projection 5.

At the center of the case body 1 is provided a holding member 7 having an elastic force slightly larger than the diameter of the center hole A1 of the disk A. When the holding member 7 is fitted into the center hole A1 of the disk A, each elastic member 7a is bent inward, and finally the inner peripheral edge of the center hole A1 of the disk A is held by the elastic force of each elastic member 7a. It is elastically held by.

[0005] The ribs 8 provided on the lid 2
And the disc A is the case body 1
It also serves as a stopper when it moves for some reason inside. When opening the lid 2 in the closed state, a finger is put on the side wall 9 and the lid 2 is rotated about the projection 3 at the rear end of the case body 1 as a fulcrum. When taking out the disk A, put a finger between the outer peripheral edge of the disk A and the center hole A1 and remove the disk A from the holding member 7 by pulling it out.

In the disk storage case having such a structure, the inside of the case body 1 is made substantially sealed by closing the lid 2, so that the stored disk A is less likely to be dusted, and furthermore, the external impact is prevented. It is effective in protecting from etc.

However, in such a disk storage case, since the inner peripheral edge of the center hole A1 of the disk A is pressed by the elastic force of each elastic body 7a of the holding member 7, the disk A must be taken out. Requires considerable pull-out force. When the disk A is pulled out, the center hole A1
The disk A may bend with the fulcrum as a fulcrum, and the recording surface of the disk A may be strongly pressed against the inner surface of the case body 1, and in such a case, the surface may be damaged.

Further, the center hole A1 of the disk A is
The outer periphery of the disk A is in a floating state, so that if the disk storage case is accidentally dropped or the carrying is unstable, the outer periphery of the disk A may flutter. As a result, the disc A may be damaged.

Further, since the lid 2 is rotatable about the rear end of the case body 1 as a fulcrum, the lid 2 is particularly large in case size and the lid 2 is open. Thus, the entire load of the lid 2 is applied to the rear end of the case body 1. For this reason, when trying to take out the disk A while supporting the case main body 1 with one hand, there is a high danger that the case main body 1 and the disk A are accidentally dropped due to an extremely unstable state. .

In order to solve such a problem, for example, a disk housing case as shown in FIG. 13 has been developed. As shown in FIG.
Are fitted in the guide grooves 11 of the case body 10, and the lid 20 is slidable with respect to the case body 10. Also, when the guide pin 21 moves to the end of the guide groove 11, the lid 20 becomes rotatable.
The lower side of the case body 10 is slid in the opposite direction with the back face up, and the engagement recesses 22 are fitted into the engagement protrusions 12, so that the entire lid 20 is held in a state of sticking to the back side of the case body 10. Is done.

To accommodate the disk A in this state, the center hole A1 is loosely fitted to the gourd-shaped holding member 13. As a result, the disk A
Is performed. At this time, the outer peripheral edge of the disk A is supported by the step portions 14a of the plurality of stoppers 14. The movement of the disk A in the horizontal direction is prevented by the stopper pieces 14b of the respective stoppers 14. Further, the movement of the disk A in the vertical direction is prevented by the two engagement projections 15 and the lock mechanism 16 arranged opposite thereto. When the lid 20 is closed, the operation is performed by the tongue piece 23 on the lid 20 side.

Each stopper 14 has a structure in which a stopper piece 14b is supported from the back side by a reinforcing rib 14c. In the lock mechanism 16, as shown in FIG. 14, the movement of the slider 18 is restricted by fitting the engagement protrusion 18 b of the slider 18 into the engagement recess 17 a or 17 b of the two holding members 17. The engagement projection 18b is engaged with the engagement recess 17b.
In the state where the engagement piece 18 of the slider 18 is
a engages with the outer peripheral edge of the disk A, and the disk A is maintained in a state where it cannot be taken out.

On the other hand, the disk A is
When the slider 18 is to be taken out from zero, the slider 18 is slid to move the engagement protrusion 18b from the engagement recess 17b to 17a, so that the engagement piece 18a is separated from the outer peripheral edge of the disk A. In this state, since the center hole A1 of the disk A is loosely fitted in the gourd-shaped holding member 13, it is extremely easy to take it out. In addition, in the state where the lid 20 is left open, the entire lid 20 is held in a state of sticking to the back side of the case main body 10. Therefore, if the user tries to take out the disk A while supporting the case main body 10 with one hand, it is extremely difficult. The case becomes stable and the case body 10 and the disc A
There is no danger of falling.

[0014]

As described above, in the above-mentioned conventional disk storage case, the cover 20 is slidably provided with respect to the case body 10, and when the cover 20 is left open, the entire cover 20 is completely opened. It is held in a state of sticking to the back side of the case body 10. For this reason, even if the size of the disk storage case becomes large, not only the opening and closing operation of the lid 20 is performed smoothly, but also if the disk A is taken out while supporting the case body 10 with one hand, it is extremely stable. Since the disk A can be taken out and stored in this state, the usability is excellent.

The horizontal movement of the disk A housed in the case body 10 is prevented by the stopper pieces 14b of the stoppers 14, and the vertical movement of the disk A is further prevented by the two engaging projections 15 and It is configured to be blocked by the lock mechanism 16 disposed opposite to the lock mechanism. When the lid 20 is closed, the tongue piece 2 on the lid 20 side
3 also restricts movement in the vertical direction.

Therefore, the operation of opening and closing the lid 20 is easy, and the storage of the disk A is performed safely and securely. Therefore, it is particularly suitable as a case for storing a large-diameter disk. However, in such a disk storage case, the operation of storing and taking out the disk is safe and easy, but in order to prevent the disk A from rattling in the horizontal and vertical directions, the plurality of stoppers 14 and the engagement protrusions 1 are provided.
5 and the lock mechanism 16 disposed opposite thereto require a large number of parts, which makes the structure complicated and increases the cost.

The present invention has been made in view of such circumstances, and has as its object to provide a disk storage case in which a disk can be locked and unlocked with respect to the case body by a one-touch operation.

[0018]

According to the present invention, there is provided a disk storage case comprising a case body for accommodating a disk and a lid for covering the case body from above. An engagement holding member having an elastic force for engaging and holding at least a part of the edge of the center hole of the disk, and a rotatably provided near the engagement holding member; A lock lever having an engaging portion that engages with an edge of a center hole of the disk from a side opposite to a holding side of the engagement holding portion and that prevents the disk from being detached together with the engagement holding member. It is characterized by doing.

[0019]

In the disk storage case of the present invention, the disk is locked to the case body by pushing the center portion of the disk so that at least a part of the edge of the center hole of the disk has an elastic holding force. The member is engaged and held, and at the same time, the engaging portion of the lock lever is engaged with the edge of the opposed center hole on the engaged and held side. On the other hand, when the disk is unlocked from the case body, the lock lever is rotated to release the engagement by the engagement portion. As a result, the reaction of the engagement portion acting on the engagement holding member does not work, so that the locked state of the center portion of the disk is released.

Next, the operation of locking and unlocking the disk A with respect to the positioning holding unit 50 will be described.
First, when the disk A is not stored in the disk storage case,
Are in a state of passing through the escape hole 34a of the bottom plate 34 of the case body 30. At this time, the locking projection 58 is
5b, and the rotation of the lock lever 56 is restricted.

In this state, the disc A is placed in the positioning and holding section 5.
0, the center hole A1 of the disk A
Is brought into contact with the inclined portion 59b of the lock lever 56, whereby the lower surface of the edge is placed on the support piece 59a. At this time, the edge of the center hole A1 facing the portion in contact with the inclined portion 59b comes into contact with the inclined surface 54b of the support portion 54.

When the center of the disk A is pushed into the bottom plate 34 of the case body 30 from this state, the lower surface of the edge of the center hole A1 of the disk A presses the support piece 59a downward.
As a result, the lock lever 56 rotates counterclockwise about the fitting position of the pin 57 in the bearing hole 55a. At this time, the locking projection 58 comes off the rotation regulating hole 55b. The rotation of the lock lever 56 in the counterclockwise direction stops when the lower surface of the support piece 59a contacts the bottom plate 34 of the case body 30.

With this rotation, the disk lock portion 59d
Are biased away from the bottom plate 34. At this time, the support piece 59a pushes up the edge of the center hole A1 of the disk A. At the same time, the edge of the center hole A1 in contact with the inclined surface 54c of the support portion 54 moves over the convex portion 54a and moves toward the inclined surface 54b. When the edge moves toward the inclined surface 54b, the support 54 is slightly bent inward, so that the edge is easily moved. The disk A is pushed up by the support piece 59a above the side wall 31 of the case body 30. Therefore, it is extremely easy to take out the disk A from the case main body 30.

As described above, in this embodiment, the ring-shaped holding portion 51 having the cutouts 52 and 53 is provided at the center of the case body 30, and the lever supporting portion 55 which is disposed inside the holding portion 51 so as to be opposed. The lock lever 56 is provided rotatably via the. The notch 52 of the holding portion 51 is provided with a support portion 54 having elasticity, and the notch 53
, The disk lock portion 59e of the lock lever 56 is positioned.

The disk A is locked by pushing the center portion of the disk A aligned with the positioning holding portion 50 so that the center hole A1 of the disk A is resilient to the disk lock portion 59e of the lock lever 56 and the elasticity of the support portion 54. It is kept locked by force. On the other hand, to release the lock of the disk A, the lock lever 56 is rotated to push up the edge of the center hole A1 of the disk A by the support piece 59a of the disk lock portion 59e. At the same time, the edge of the center hole A1 in contact with the inclined surface 54c of the support portion 54 moves over the convex portion 54a and moves toward the inclined surface 54b.

Thus, the locking and unlocking of the disk A is performed by a one-touch operation. 6 to 11 show another embodiment in which the configuration of the positioning and holding unit in FIG. 1 is changed. In the drawings described below, portions common to FIGS. 1 to 5 are denoted by the same reference numerals, and redundant description will be omitted. As shown in these figures,
The holding portion 51 is provided with a lever support portion 55 integrally opposed to the lever support portion 55. In addition, a relief portion 51a having a reduced wall height is provided near the lever finger contact portion of the holding portion, so that a finger can be easily applied when the disc is taken out.

Is stopped when the lower surface thereof contacts the bottom plate 34 of the case body 30. At this time, since the contact protrusion 56b contacts the protrusion 34b provided on the bottom plate 34, the horizontal state of the lock lever 56 is maintained together with the support piece 59a.

At this time, the inclined surface 54b of the support portion 54
The edge of the center hole A1 which is in contact with is moved over the convex portion 54a to the side of the inclined surface 54c. Slope 54 of this edge
At the time of movement to the side c, the support portion 54 is slightly bent inward, so that unnecessary force is not required when pushing the center portion of the disk A. Further, at this time, the locking projection 58 is removed from the locking groove 55d.

As a result, the center hole A1 of the disk A is connected to the disk lock 59d of the lock lever 56 and the support 5
4 is held in a locked state by the elastic force. On the other hand, when releasing the locked state of the disc A, when the finger contact portion 56a of the lock lever 56 is pushed in, the finger contact portion 56a rotates around the long hole 55c as a fulcrum, passes through the escape hole 34a, and is It moves to below 30 bottom plate 34.

With this rotation, the support piece 59a pushes up the edge of the center hole A1 of the disk A. At the same time, the edge of the center hole A1 in contact with the inclined surface 54c of the support portion 54 moves over the convex portion 54a and moves toward the inclined surface 54b.
When the edge moves toward the inclined surface 54b, the support 5
4 is slightly bent inward, so that its edge can be easily moved. At this time, the locking projection 58 fits into the locking groove 55d, and the lower portion 56c of the finger contact portion 56a contacts the edge of the escape hole 34a of the bottom plate 34, whereby the rotation of the lock lever 56 is restricted. .

As described above, in this embodiment, the lever supporting portion 55 disposed opposite to the ring-shaped holding portion 51 is integrally provided on the ring-shaped holding portion 51 so that the lever supporting portion 55 is shifted from the center of the holding portion 51.
