Description

[Detailed description of the device]

[0001]

[Industrial application]

 The present invention relates to an improvement of an optical disc storage case for storing an optical disc for audio or data, which is commercially available under the name of a so-called compact disc.

[0002]

[Prior Art]

 The optical disc as described above has a thin disc shape as shown in FIGS. 6 and 8, for example. Therefore, when the optical disc a is mounted in a compact disc player or the like, the clamper of the rotary spindle is mounted. It has a clamp hole b for mounting. A conventional case for storing this optical disk for the purpose of storage or the like is as shown in FIG. 6, and the optical disk is held by the clamp hole b so as not to move. That is, this storage case is rotatably pivotally attached to a shallow rectangular box 1 made of a transparent resin such as polystyrene and a fulcrum 7 on one side of the box 1 to open and close the box 1. And a lid 2 that can be used. The box 1 has a disc holder 3 fitted therein so as not to move, and the lid 2 closes the box 1 so as to completely cover it.

A shallow circular recess 4 having a diameter slightly larger than the diameter of the optical disc a is formed in the center of the disc holder 3, and the recess 4 is open at both sides of the disc holder 3. A holding projection 5 is provided in the center of the recess 4 so as to be fitted into the clamp hole b of the optical disk a and hold the optical disc a in the recess 4 so as not to move. As shown in FIG. 7, the holding projection 5 is formed by arranging and arranging inverted L-shaped claws 6 around the center of the concave portion 4, with the tip of the claw 6 facing the center. The array outer diameter of these claws 6 is set to be slightly larger than the clamp hole b of the optical disk a.

When the optical disc a is stored in this storage case, as shown in FIG. 6, the optical disc a is stored in the recess 4 of the disc holding body 3 and the clamp hole b thereof is opened from the state where the lid 2 is opened. Then, the clamp hole b is fitted around the claw 6 of the holding projection 5 by pushing around the claw 6 with a finger. At this time, the claw 6 is fitted into the clamp hole b while being tilted toward the center against the elastic force, and after fitting, it is expanded by the elastic force to fix the clamp hole b from the inside. Is held in the center of the concave portion 4 of the disc holder 3. In this state, the lid body 2 is closed to the box body 1 side so that the optical disc a is stored in the storage case so as not to move. Further, from this state, when taking out the optical disk a from the storage case, the lid 2 is opened and the tip of the claw 6 in the clamp hole b of the optical disk a is pushed with the thumb. Then, the claws 6 bend, and they are separated from the peripheral surface of the clamp hole b, and the optical disk a can be separated. Then, on one side of the side of the disc holder 3 in which the recess 4 is opened, for example, the tip of the index finger is brought into contact with the outer peripheral edge of the optical disc a, so that the optical disc a is slightly floated out of the recess 4, and The thumb after pressing the claw 6 is brought into contact with the clamp hole b, and the optical disk a is radially sandwiched by the thumb and the index finger. As a result, it becomes possible to hold the optical disk a with one hand c and carry it to the compact disk player as shown in FIG. In this case, the index finger and the thumb may be reversed, that is, the outer circumference of the optical disk a may be held by the thumb and the inner circumference of the clamp hole b may be held by the index finger.

[0005]

[Problems that the device is trying to solve]

 However, when the optical disc a is taken out from the storage case as described above, because the thumb pushes the head of the nail 6, the optical disc a is ejected using the thumb d and the other finger e as shown in FIG. It must be sandwiched between its outer peripheral edge and the inner peripheral edge of the clamp hole b. However, when the optical disc a is sandwiched in this way, it is difficult to set it on the compact disc player. Moreover, since the finger has to be inserted into the clamp hole b of the small optical disk a, the optical disk a cannot be stably held, and the optical disk a is often dropped. On the other hand, when the optical disk a is clamped together at the outer peripheral edge and is to be taken out from the storage case, it is necessary to use another finger to push the claw 6. For example, the outer peripheral edge of the optical disk a is sandwiched between the index finger and the middle finger, and the finger 6 is used to push the nail 6, or it is necessary to use an unreasonable finger, or the finger of the other hand is used. It is troublesome that the optical disk a cannot be taken out from the storage case.

Further, when the optical disc a is stored in the storage case as described above, after the optical disc a is placed in the recess 4 of the disc holder 3, the finger is once removed from the optical disc a, and the area around the clamp hole b is removed. The clamp hole b must be fitted around the claw 6 of the holding projection 5 by pushing it with a finger. Therefore, the finger has to be moved twice, which is also troublesome. SUMMARY OF THE INVENTION The present invention has been made in view of such conventional problems, and an object thereof is to provide an optical disk storage case in which an optical disk can be easily stored and taken out with only two fingers.

[0007]

[Means for Solving the Problems]

 That is, in order to achieve the above-mentioned object, the gist of the means adopted by the present invention is a box body for housing an optical disc, a lid body which is openably and closably attached to the box body, and a central portion of the box body. And a fixing portion fitted in a clamp hole opened at the center of the optical disc, the fixing portion includes a pair of facing at least one slidable in the width direction of the disc holder. A spring, which is made up of protrusions and biases elastic force in a direction to separate them from each other, is mounted, and an operating end portion of a lever for moving the sliding protrusion against the spring is held by a disc holder. The optical disk storage case is characterized in that it is provided on a side portion of the optical disk.

[0008]

[Action]

 In the optical disk storage case, the fixing portion that fits into the clamp hole formed in the center of the optical disk is composed of a pair of opposed projections, at least one of which is slidable in the width direction of the disk holding body. Since a spring that biases the elastic force in the direction of separating is installed, the gap between the protrusions is narrowed against the elastic force of this spring, the clamp hole of the optical disk is fitted on the outside, and the protrusion is returned by the elastic force of the spring. By this, the interval between the protrusions is widened and the clamp hole of the optical disc is held so as not to come off. Further, from this state, the clamp hole of the optical disk can be pulled out by narrowing the interval between the protrusions against the elasticity of the spring. Since the operating end of the lever that moves this protrusion against the elastic force of the spring is provided on the side of the disc holder, the operating end of the lever can be operated with one or both fingertips that are applied to the outer peripheral edge of the optical disc. The space between the protrusions can be narrowed against the elasticity of the spring simply by pushing the part.

[0009]

【Example】

 Next, embodiments of the present invention will be described in detail with reference to the drawings. 1 to 3 show a first embodiment of the present invention, the optical disk storage case shown here is basically the same as the conventional optical disk storage case shown in FIG. The same reference numerals are used for the common portions. That is, the storage case shown in FIG. 1 has a shallow rectangular box body 1 made of a transparent resin such as polystyrene, and one side of the box body 1 rotatably pivoted with a fulcrum 7 to support the box body 1 It has a lid 2 that can be opened and closed. The box 1 has a disk holder 3 fitted therein so that it does not move, and the lid 2 closes the box 1 so as to completely cover the disk holder 3.

A shallow circular recess 4 having a diameter slightly larger than that of the optical disc a is formed in the center of the disc holder 3, and both sides of the recess 4 are open at both sides of the disc holder 3. Further, a fixing portion is provided at the center of the concave portion 4 so as to be fitted into the clamp hole b of the optical disk a and hold the optical disc a in the concave portion 4 so as not to move. That is, a circular through hole 12 is formed in the center of the concave portion 4 of the disc holder 3, and the fixed portion is opposed to the fixed portion slidably mounted in the through hole in the width direction of the disc holder 3. It comprises a pair of protrusions 8 and 8 and a spring 9 which is mounted between the protrusions 8 and 8 and which biases elastic force so that they are separated from each other. The protrusion 8 has a slightly enlarged head, and the two-dimensional shapes thereof are arcuate shapes symmetrical to each other, and the maximum separation distance thereof is regulated by the through hole 12.

As shown in FIGS. 2 and 3, between the disc holder 4 and the bottom surface of the box body 1, a guide groove 13 having a rectangular cross section is provided at a portion passing through the through hole 12. The ends of the guide grooves 13 reach both sides of the disc holder 3. Semicircular notches 14 are provided on both sides of the disc holder 3 having the guide groove 13 opened. A long flat plate-shaped lever 10 integrally connected to the projection 8 is slidably fitted in the guide groove 13, and its operating end 11 projects from the notch 14 to both sides of the disc holder 4. Therefore, as shown by the arrows in FIGS. 1 and 2, by pushing this operation end portion 11 from both sides toward the center side of the disc holder 3, the protrusion 8 is narrowed against the elasticity of the spring 9. When the pushing of the operating end 11 is stopped, the protrusion 8 is expanded by the elasticity of the spring 9. It should be noted that when the projections 8, 8 are spread by the elastic force of the spring 9, the operation end portion 11 is inside the lid body 2 closed on the side of the box body 1 so as not to interfere with the operation end portion 11, and the disc holder The optical disk a housed in the concave portion 3 of the optical disk 3 is located outside or below the outer peripheral edge of the optical disk a.

In this optical disk storage case, the operation end 11 is pushed from both sides toward the center side of the disc holder 3 as described above, and the protrusion 8 is narrowed against the elastic force of the spring 9. The protrusion 8 can be fitted into the clamp hole b opened at the center of the optical disk a. After that, the pushing of the operation end portion 11 is stopped and the protrusion 8 is returned by the elastic force of the spring, so that the interval between the protrusions 8 is widened, and the clamp hole b of the optical disk a is opened as shown by the chain double-dashed line in FIG. It is held so that it does not come off. Further, from this state, the operating end portion 11 is pushed from both sides toward the center side of the disc holder 3 to reduce the distance between the protrusions 8 against the elastic force of the spring 9 so that the clamp hole b of the optical disc a is fixed. You can pull it out from there. In this case, since the operating ends 11 of the lever 10 for moving the protrusion 8 are on both sides of the disc holder 4, the operating end 11 of the lever 10 can be pushed in with a fingertip that holds the optical disc a. ..

Next, the second embodiment of the present invention shown in FIGS. 4 and 5 will be described. Here, one protrusion 8 ′ is fixed to the disk holder 3 and only the other protrusion 8 is fixed. Is slidable in the width direction of the disc holder 3. Therefore, the lever 10 having the operating end 11 is provided only on one of the protrusions 8 on the sliding side, and the operating end 11 is provided only on one side of the disc holder 3. Others are the same as those in the first embodiment. In the optical disk storage case according to the second embodiment, the operating end 11 is pushed toward the center side of the disk holder 3 and only one of the protrusions 8 is narrowed against the elasticity of the spring 9. The projection 8 can be fitted in or disengaged from the clamp hole b opened at the center of the.

[0014]

[Effect of the device]

 As described above, according to the present invention, when the clamp hole b of the optical disc a is fitted into or removed from the central protrusion 8 of the disc holder 3, the central protrusion 8 of the disc holder 3 is finger-tipped. It is not necessary to operate, and it is possible only by pushing the operation end portion 11 of the lever 10 on the outer peripheral side of the optical disk a. Therefore, it is possible to provide a storage case in which the optical disc can be easily stored and taken out with only two fingers that hold the outer peripheral edge side of the optical disc a.
