Description

[Detailed Description of the Invention] The present invention relates to a compact disk storage case in which the compact disk can be easily put in and taken out so that the compact disk is not easily scratched.

Conventionally, as a case for storing a compact disk, there is a case as shown in FIG. That is, the case body 1
A concave portion 2 having a circular shape larger than the outer diameter of the compact disk and having a notch 2A formed in a part of the circular shape is provided in the center of the concave disk, and the inner peripheral portion of the compact disk ( A contact portion 3 for contacting a non-signal portion) is provided in a protruding manner, and a resin clamper 4 press-contacted to the inner peripheral surface of the compact disk is provided in the center of the contact portion 3.

In FIG. 1, reference numeral 5 is a lid, and the chain double-dashed line in FIG. 1 (b) is a compact disk.

The compact disc is stored in the case body 1 by grasping the compact disc, aligning the inner peripheral surface of the compact disc with the clamper 4, and pressing the inner peripheral portion of the compact disc strongly. Further, the removal of the compact disc from the case body 1 is performed by grasping and pushing up the portion of the compact disc located at the notch 2A.

Since the compact disk is supported by the contact portion 3 in the housed state, the signal surface of the compact disk does not touch the bottom surface of the recess 2, but it is necessary to apply a force to the compact disk at the time of taking in and out. Therefore, the operation is not easy, and for that reason, there is a drawback that unreasonable force is applied to the compact disc or the compact disc is damaged.

The present invention was made in order to eliminate such drawbacks, and provided with a case body formed by inserting a compact disc and a lid body for closing the opening of the case body, respectively. A plate in which a V-shaped groove is formed on the back surface of the lid body by cutting out a substantially triangular hypotenuse in a semicircular shape on the back surface of the lid body Is fixed in a downward-sloping manner, and the outer peripheral edge portion of the compact disc is held and fixed by both slopes of the V-shaped groove.

The invention will be described below with reference to the drawings.

FIG. 2 is a diagram showing an embodiment of the present invention. In FIG. 2, 11 is a V-shaped groove, 12 is an arc surface, 13 is a plate, 14 is a compact disc, 15 is a lid, and 16 is a case body. The case body 16 is formed by inserting a compact disc, and the lid body 15 is formed by opening a closed portion of the case body 16. On the back of the lid 15,
A plate 13 in which a V-shaped groove 11 is formed on a circular arc surface 12 in which a hypotenuse of a substantially triangular shape is cut out in a semicircle shape is fixed in a downward-sloping manner with the hypotenuse left with the lid 15 open.

The V-shaped groove 11 is formed by inserting a score line in the center of the arc surface 12 and pushing open the upper end of the arc surface 12. Or V
The V-shaped groove 11 is formed by excavating the arc surface 12. The size of the V-shaped groove 11 is determined so as to support the outer peripheral edge portion of the compact disk 14 on both slopes thereof, as shown in FIG. When the compact disc 14 is inserted into the V-shaped groove 11, the outer peripheral edge portion is clamped / fixed to both slopes of the V-shaped groove 11, and there is no contact between the recording portions. The V-shaped groove 11 is provided over the entire circumference of the arc surface 12, but the arc surface 12 may be provided with irregularities at regular intervals and may be provided on the convex surface. Locking protrusions 15A are provided at arbitrary positions on both side surfaces of the lid body 15.
A is engaged with an engaging recess 16A provided in both side plates 161 of the case body 16. By this locking, the lid 15
Are held by the case body 16 when closed. Further, a pair of engaging plates 15B having engaging holes 15C are provided at the other end of the back surface of the lid body 15, and the engaging plates 15B are provided with engaging pins 16B which are provided so as to face each other under the side plates 161. Is engaged with. By this locking, the lid body 15 opens and closes. A handle (not shown) is provided on one end of the front surface of the lid body 15 so as to project therefrom.

Note that an opening may be provided in all or part of the upper plate that forms the case body 16, and the upper lid that closes the opening may be connected to the lid 15 that is the side lid. Also, a single pin may be used instead of the pair of engagement pins 16B.

When a handle (not shown) is pulled, the lid 15 rotates about the engagement pin 16B, the engagement between the engagement projection 15A and the engagement recess 16A is released, and the lid 15 opens. When the lid 15 is pushed up, the lid 15 rotates, the locking projection 15A and the locking recess 16A are locked, the lid 15 is closed, and the opening of the case body 16 is closed.

For loading and unloading the compact disc 14, the lid 15 is opened, the compact disc 14 is grasped by its inner peripheral surface and outer peripheral surface, lifted from the V-shaped groove 11, and the V-shaped groove 11
Put it in. Therefore, the compact disc 14 can be easily taken in and out, and no force is applied to the compact disc 14 when the compact disk 14 is taken in and out, and the compact disc 14 is not scratched.

The above is the case where the V-shaped groove 11 is provided in the lid body 15. However, as shown in FIG. 4, the case body 16 is provided with a concave portion 17 having a shape in which the facing portion is cut out of the circle. Then, the outer peripheral surface of the concave portion 17 is cut obliquely upward from the bottom surface to form the inclined surface 17
A is formed, and the compact disk 14 is formed at the center of the recess 17.
An abutting portion 18 that abuts the inner peripheral portion of the compact disc 14 is provided at the center of the abutting portion 18, and a guide 19 having a diameter smaller than the diameter of the central hole of the compact disk 14 is also provided at the center of the abutting portion 18. , The concave portion 20 which is equal to the inclined surface 17A, and the inclined surface 2
0A may be formed, and the V-shaped groove 11 may be formed by the inclined surface 17A and the inclined surface 20A. In this case, the compact disk 14 is grasped by the outer peripheral surface thereof, but it is not necessary to apply a force to the compact disk 14 when taking it in and out.

As described above, according to the present invention, the case body formed by inserting the compact disc and the lid body that closes the opening of the case body are locked by the locking means respectively provided, On the back surface of the lid body, a plate having a V-shaped groove formed in an arc surface in which a hypotenuse of a substantially triangular shape is cut out in a semicircular shape is fixed in a state in which the hypotenuse is downward left with the lid body opened, By holding and fixing the outer peripheral edge portion of the compact disc on both slopes of the V-shaped groove, the compact disc can be easily taken in and out, and the compact disc is hardly scratched.
