[Industrial applications]

 The present invention relates to a disc storage case for storing optical discs such as LDs, CDs and CDVs.

[0002]

[Prior art]

 Conventionally, as a disk storage case for storing an optical disk such as an LD, a CD or a CDV, a case body provided with a lid which can be opened and closed has been used.

FIG. 12 shows an example of such a disk storage case, which comprises a case body 1 and a lid 2. Protrusions 3 are provided on both sides of the rear end portion of the case body 1, and the engagement holes 4 of the lid body 2 are fitted into the protrusions 3 so that the lid body 2 can be opened and closed with respect to the case body 1. It A locking projection 5 is provided in the vicinity of each projection 3, and the locking recess 6 on the lid 2 side is fitted into the locking projection 5 to lock the lid 2 on the case body 1.

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

The ribs 8 provided on the lid body 2 give strength to the lid body 2 and also serve as stoppers when the disk A moves inside the case body 1 for some reason. When the lid body 2 in the closed state is opened, a finger is put on the side wall 9 and the lid body 2 is rotated around the protrusion 3 at the rear end of the case body 1. When taking out the disc A, put a finger between the outer peripheral edge of the disc A and the center hole A1 and pull out the disc A from the holding member 7 to remove it.

In the disk storage case having such a structure, since the inside of the case body 1 is made substantially sealed by closing the lid body 2, it is difficult for dust to be attached to the stored disk A, and further, the external case is not provided. It is effective in protecting from impacts.

However, in such a disc storage case, since the inner peripheral edge of the center hole A 1 of the disc A is pressed by the elastic force of each elastic body 7 a of the holding member 7, the disc A cannot be taken out. Requires a considerable pulling force. Also, when the disk A is pulled out, the disk A may bend around the center hole A1 as a fulcrum, and the recording surface of the disk A may be strongly pressed against the inner surface of the case body 1. In such a case, the surface is damaged. There is also a risk that

Further, the structure is such that the center hole A1 of the disk A is pressed and held by the holding member 7, and the outer peripheral portion of the disk A is in a floating state, so that the disk storage case cannot be accidentally dropped or cannot be carried easily. In the case of stability, the outer peripheral portion of the disc A may flutter and the disc A may be scratched.

Further, since the lid body 2 has a structure in which the rear end portion of the case body 1 is rotatable, the lid body 2 is in a state where the lid body 2 is open, especially in a case having a large size. As a result, the total load of the lid body 2 is applied to the rear end of the case body 1. Therefore, when attempting to take out the disc A while supporting the case body 1 with one hand, there is a risk that the case body 1 and the disc A may be accidentally dropped due to an extremely unstable state. high.

In order to solve such a problem, for example, a disk storage case as shown in FIG. 13 has been developed. As shown in the figure, the guide pin 21 of the lid 20 is fitted in the guide groove 11 of the case body 10, and the lid 20 is slidable with respect to the case body 10. When the guide pin 21 is moved to the end of the guide groove 11, the lid body 20 can be rotated. Therefore, with the lid body 20 facing up, the lower side of the case body 10 is slid in the opposite direction. By fitting the mating recess 22 into the engaging projection 12, the entire lid 20 is held in a state of sticking to the back side of the case body 10.

When housing the disk A in this state, the center hole A 1 thereof is loosely fitted in the gourd-shaped holding member 13. As a result, the position of the disk A is determined inside the case body 10. At this time, the outer peripheral edge portion of the disk A is supported by the step portions 14a of the plurality of stoppers 14. Further, the movement of the disk A in the horizontal direction is blocked by the stopper pieces 14b of the stoppers 14. Further, the movement of the disk A in the vertical direction is prevented by the two engaging projections 15 and the locking mechanism 16 arranged so as to face the engaging projections 15. When the lid body 20 is closed, the tongue piece 23 on the lid body 20 side is also used.

Each stopper 14 has a structure in which the stopper piece 14b is supported from the back side by a reinforcing rib 14c. Further, in the lock mechanism 16, as shown in FIG. 14, the movement of the slider 18 is restricted by fitting the engagement protrusion 18b of the slider 18 into the engagement recess 17a or 17b of the two holding members 17. When the engagement protrusion 18b is fitted in the engagement recess 17b, the engagement piece 18a of the slider 18 engages with the outer peripheral edge of the disc A, and the disc A is taken out. Is kept in an impossible state.

On the other hand, when the disk A is taken out from the case main body 10, when the slider 18 is slid to move the engagement protrusion 18b from the engagement recess 17b to the engagement recess 17a, the engagement piece 18a of the disk A is moved. Move away from the outer edge. In this state, the central hole A1 of the disk A is loosely fitted in the gourd-shaped holding member 13, so that the removal thereof is extremely easy. Further, when the lid body 20 is left open, the entire lid body 20 is held in a state of sticking to the back side of the case body 10. Therefore, when attempting to take out the disc A while supporting the case body 10 with one hand, it is extremely difficult. It becomes stable and there is no risk of accidentally dropping the case body 10 and the disk A.

[0014]

[Problems to be solved by the device]

 As described above, in the above-described conventional disc storage case, the lid body 20 is slidably provided on the case body 10, and when the lid body 20 is left open, the entire lid body 20 sticks to the back side of the case body 10. Retained. Therefore, not only the lid 20 can be opened and closed smoothly even when the size of the disk storage case is increased, but also when the disk A is taken out while supporting the case body 10 with one hand, Since the disk A can be taken out and stored in an extremely stable state, it has excellent usability.

Further, the horizontal movement of the disk A housed in the case body 10 is blocked by the stopper pieces 14b of the stoppers 14, and the vertical movement thereof is further suppressed by the two engaging projections 15 and Is configured to be blocked by a lock mechanism 16 arranged so as to oppose to. When the lid 20 is closed, the tongue piece 23 on the lid 20 side also restricts the movement in the vertical direction.

Therefore, since the opening / closing operation of the lid 20 is easy and the disc A can be stored safely and securely, it is particularly suitable as a case for storing a large-diameter disc. However, in such a disk storage case, while the disk storage and removal operations are safe and easy, a plurality of stoppers 14 and engaging protrusions are provided to prevent the disk A from rattling in the horizontal and vertical directions. Since 15 and the lock mechanism 16 arranged opposite thereto are required, the number of parts is extremely large, the structure is complicated, and the cost is increased.

The present invention has been made in view of such circumstances, and an object thereof is to provide a disk storage case capable of locking and unlocking a disk with respect to the case body side by a one-touch operation. And

[0018]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention provides a disc storage case, which comprises a case body for storing a disc and a lid body for covering the case body from above, the disc storage case being provided at the center of the inside of the case body. An engaging and holding member having an elastic force that engages and holds at least a part of the edge portion of the center hole, and is rotatably provided in the vicinity of the engaging and holding member and held by the engaging and holding portion.

Tongue pieces 43, 44 are provided on the inner surface side of each side plate 41, and contact the upper end edge portion 31a of the side wall 31 on the case body 30 side when the lid 40 is closed. Each tongue piece 44 is provided with a spherical projection 45 that comes into contact with the outer peripheral edge of the disk A when the lid 40 is closed. A guide shaft 46 guided by the guide groove 32 on the case body 30 side is provided near each tongue piece 44. In the vicinity of each tongue piece 43, there is provided a rotation restricting shaft 47 for entering the guide groove 32 from the escape groove 32a and restricting the rotation of the lid 40 when the lid 40 is closed. . Further, in the vicinity of each tongue piece 43, an engaging recess 48 is provided which is fitted into the engaging protrusion 33 on the case body 30 side when the lid 40 is closed.

2 to 5 show the details of the positioning holding portion 50, in which a ring-shaped holding portion 51 having a slightly smaller diameter which is aligned with the central hole A1 of the disk A is provided in a protruding manner. . The outer peripheral edge portion of the holding portion 51 has a shape that is slightly inclined inward. This facilitates alignment and fitting of the central hole A1 of the disc A to the holding portion 51. An escape hole 34a for a lock lever 56, which will be described later, is formed inside the holding portion 51.

Notches 52 and 53 are provided at the positions facing each other in the radial direction of the holding portion 51. The notch 52 is provided with a support portion 54 having an elastic surface and an inclined surface 54b that inclines inward and an inclined surface 54c that inclines outward with the convex portion 54a as a boundary. Two lever support parts 55 are arranged facing each other inside the holding part 51.

A bearing hole 55a and a rotation restricting hole 55b provided at a position lower than the bearing hole 55a are formed in each lever support portion 55. A columnar pin 57 of a lock lever 56 is inserted into each bearing hole 55a. Regarding the lock lever 56, one having a shape shown in either FIG. 2A or FIG. 2B is used. In the lock lever 56 shown in FIG. 5A, the finger rest portion 56a is extended horizontally and a finger engagement groove 59f is formed in the finger rest portion 56a. In the lock lever 56 of FIG. 6B, the finger contact portion 56a is provided at a position one step lower through the step portion 59d.

The lock lever 56 is provided with a locking projection 58 which is fitted into the rotation restricting hole 55b when the finger rest 56a is pushed to rotate the lock lever 56 in the time direction (see FIG. 5). Has been. A disk lock portion 59e is provided at an end of the lock lever 56 via a thin portion 59c. The disc lock portion 59e is provided with a support piece 59a for supporting the edge portion of the center hole A1 from the lower surface side of the disc A and an inclined portion 59b for preventing the edge portion of the center hole A1 from being detached together with the support portion 54. There is.

Here, the inclined portion 59b comes into contact with the edge of the center hole A1 of the disc A from above when the disc A is locked. When the lock lever 56 is unlocked, it contacts the end face of the center hole A1 of the disk A. As a result, the state in which the inclined portion 59b abuts against the edge of the center hole A1 from above is released, and the regulation when the center portion of the disk A is moved upward is released. Further, a convex portion 59g is provided on the upper end of the inclined portion 59b to prevent the disc from rising when the lock is released.

Note that, in FIG. 5, the rotation fulcrum position h3, which is the fitting position of the pin 57 of the lock lever 56 and the pin 57 into the bearing hole 55a, is the same as the position h1 of the upper end surface of the disk A in the locked state. It is provided between the disc and the position h2 of the lower end surface of the disc A in the released state. As a result, the center of gravity of the disk A in the locked state is lower than the rotation fulcrum position of the lock lever 56, so that the locked state by the lock lever 56 is voluntarily caused by vibration during carrying the disk storage case. On the contrary, it will not be released. Distance from the rotation fulcrum to the end surface of the disk center hole A1

[Outer 1] And the distance from the fulcrum to the finger rest 56a

[Outside 2] Is

[Equation 1] Is set to be As a result, the pushing force required to eject the disc is small.

The lid 40 is opened and closed with respect to the case main body 30 in the disc storage case having the above-described configuration as follows. First, when the lid 40 is closed with respect to the case body 30, the rotation restricting shaft 47 on the lid 40 side is located at the starting end of the guide groove 32. As a result, the movement of the lid 40 in the arrow b direction is restricted. The guide shaft 46 is located in the middle of the guide groove 32. At this time, since the engaging recess 48 on the lid 40 side is fitted into the engaging protrusion 33, the movement of the lid 40 in the arrow a direction is restricted.

When a force is applied to the lid 40 in the direction of arrow a from this state, the engaging recess 48 on the lid 40 side is disengaged from the engaging protrusion 33, and the movement of the lid 40 in the direction of arrow a is restricted. It will be canceled. When a force is further applied to the lid 40 in the direction of arrow a, the guide shaft 46 and the rotation restricting shaft 47 move in the same direction along the guide groove 32. At this time, the tongues 43 and 44 move in the direction of the arrow a while being in contact with the upper edge 31a of the side wall 31, so that the lid 40 can be slid in a horizontal position. When the guide shaft 46 moves to the terminal end of the guide groove 32, the movement of the lid 40 in the arrow a direction is blocked. At this time, the rotation restricting shaft 47 is located below the escape groove 32a.

In this state, when the lid 40 is rotated clockwise about the guide shaft 46 as a fulcrum, the rotation restricting shaft 47 passes through the escape groove 32a, so that the engagement with the guide groove 32 is released. When the lid 40 is further rotated in the clockwise direction, the edge of the side wall 42 contacts the back side of the case body 30, and the rotation of the lid 40 is restricted.

On the other hand, when the lid 40 is closed, when the guide shaft 46 is rotated in the counterclockwise direction opposite to the above, the rotation restricting shaft 47 passes through the escape groove 32a and inside the guide groove 32. Fit in. When a force is applied to the lid 40 in the direction of arrow b in this state, the guide shaft 46 and the rotation restricting shaft 47 move in the same direction along the guide groove 32. At this time, since the tongues 43 and 44 move in the direction of the arrow b while being in contact with the upper end edge 31a of the side wall 31, the lid 40 can be slid in a horizontal position. When the rotation restricting shaft 47 moves to the starting end of the guide groove 32, the movement of the lid 40 in the arrow b direction is blocked. At this time, the engaging recess 48 on the lid 40 side is fitted into the engaging protrusion 33, and movement of the lid 40 in the direction of arrow a is restricted.

Next, the operation of locking and unlocking the disk A with respect to the positioning and holding section 50 will be described. First, in a state where the disc A is not stored in the disc storage case, the finger contact portion 56a of the lock lever 56 is 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 fitted into the rotation restriction hole 55b, and the rotation of the lock lever 56 is restricted.

When the disc A is held by the positioning and holding portion 50 in this state, first, the end face of the center hole A1 of the disc A is brought into contact with the inclined portion 59b of the lock lever 56, so that the lower surface of the edge portion is moved. It is placed on the support piece 59a. At this time, the edge portion side of the central hole A1 facing the portion in contact with the inclined portion 59b is in contact with the inclined surface 54b of the support portion 54.

When the center portion of the disc A is pushed into the bottom plate 34 side of the case body 30 from this state, the lower surface of the edge portion of the center hole A1 of the disc A pushes the support piece 59a downward. As a result, the lock lever 56 rotates counterclockwise with the fitting position of the pin 57 in the bearing hole 55a as a fulcrum. At this time, the locking protrusion 58 is disengaged from the rotation restricting hole 55b. The rotation of the lock lever 56 in the counterclockwise direction is stopped when the lower surface of the support piece 59a contacts the bottom plate 34 of the case body 30.

At this time, the edge of the central hole A1 that is in contact with the inclined surface 54b of the support portion 54 rides over the convex portion 54a and falls toward the inclined surface 54c. When the edge portion moves to the side of the inclined surface 54c, the supporting portion 54 slightly bends inward, so that an unnecessary force is not required when pushing the center portion of the disk A. The center hole A1 of the disk A is held in the locked state by the elastic force of the disk lock portion 59e of the lock lever 56 and the support portion 54.

On the other hand, in order to release the locked state of the disk A, when the finger rest 56a of the lock lever 56 is pushed in, the finger rest 56a rotates about the fitting position of the pin 57 with respect to the bearing hole 55a as a fulcrum. Then, it passes through the escape hole 34a and moves to the lower side of the bottom plate 34 of the case body 30. When the lock lever 56 is rotated to the final position, the locking projection 58 is fitted into the rotation restricting hole 55b to restrict the rotation.

With this rotation, the disc lock portion 59d is biased in a direction 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. Along with this, the edge portion of the central hole A1 which is in contact with the inclined surface 54c of the support portion 54 moves over the convex portion 54a and moves to the inclined surface 54b side. When the edge portion is moved to the inclined surface 54b side, the support portion 54 is slightly bent inward, so that the edge portion 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 disc A from the case body 30.

As described above, in this embodiment, the ring-shaped holding portion 51 having the notches 52 and 53 is provided in the central portion of the case main body 30, and the lever supporting portion is arranged inside the holding portion 51 so as to face each other. A lock lever 56 is rotatably provided via 55. Further, the notch portion 52 of the holding portion 51 is provided with a support portion 54 having an elastic force, and the notch portion 53 is provided with the disc lock portion 59e of the lock lever 56.

To lock the disk A, the center hole A 1 of the disk A is pushed into the center part of the disk A aligned with the positioning holding part 50 so that the disk lock part 59 e of the lock lever 56 and the support part 54. It is held in the locked state by the elastic force of. On the other hand, to unlock the disc A, the lock lever 56 is rotated to push up the edge of the center hole A1 of the disc A by the support piece 59a of the disc lock portion 59e. At the same time, the edge portion of the central hole A1 that is in contact with the inclined surface 54c of the support portion 54 moves over the convex portion 54a and moves to the inclined surface 54b side.

As a result, the disc A is locked and unlocked by a one-touch operation. 6 to 11 show another embodiment in which the configuration of the positioning and holding portion in FIG. 1 is changed. In the drawings described below, parts common to those in FIGS. 1 to 5 are designated by the same reference numerals, and duplicated description will be omitted. As shown in these drawings, the holding portion 51 is provided with a lever support portion 55 integrally facing each other. In addition, a relief portion 51a having a reduced wall height is provided in the vicinity of the lever finger contact portion of the holding portion so that the finger can be easily hooked when the disc is taken out.

An elongated hole 55c and a locking groove 55d are formed in each lever support portion 55. The lock lever 56 is provided with a pin 57 that is fitted into the elongated hole 55c and a hook-shaped locking projection 58 that is fitted into the locking groove 55d when the lock lever 56 rotates to the unlocking side. The locking projection 58 is elastically supported via a support piece 58a having an elastic force. Further, a finger engagement groove 59c is provided on the upper surface side of the lock lever 56, and the lower surface side thereof has the same rotation axis center that abuts the protrusion 34b provided on the bottom plate 34 of the case body 30. A contact protrusion 56b having an arc-shaped portion 56d is provided.

The locking and unlocking of the disk A with respect to the positioning and holding section 50 is performed as follows. First, in a state where the disc A is not stored in the disc storage case, the finger contact portion 56a of the lock lever 56 is 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 fitted in the locking groove 55d, and the lower portion 56c of the finger contact portion 56a abuts on the edge of the escape hole 34a of the bottom plate 34, whereby the lock lever 56 is rotated. It is regulated.

In order to hold the disc A in the positioning holding portion 50 in this state, first, the center hole A1 of the disc A is brought into contact with the inclined portion 59b of the lock lever 56, and the lower surface of the edge portion thereof is brought into contact with the supporting piece 59a. Abut. When the center portion of the disc A is pushed into the bottom plate 34 side of the case body 30 from this state, the lower surface of the edge portion of the center hole A1 of the disc A pushes the supporting piece 59a downward. As a result, the lock lever 56 rotates counterclockwise about the elongated hole 55c as a fulcrum. The rotation of the lock lever 56 in the counterclockwise direction is stopped when the lower surface of the support piece 59a comes into contact with 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 edge portion of the central hole A1 which is in contact with the inclined surface 54b of the support portion 54 moves over the convex portion 54a and moves to the inclined surface 54c side. When the edge portion moves to the side of the inclined surface 54c, the supporting portion 54 slightly bends inward, so that an unnecessary force is not required when pushing the center portion of the disk A. Further, at this time, the locking protrusion 58 is removed from the locking groove 55d.

As a result, the center hole A1 of the disc A is held in the locked state by the elastic force of the disc lock portion 59d of the lock lever 56 and the support portion 54. On the other hand, in order to release the locked state of the disk A, when the finger rest 56a of the lock lever 56 is pushed in, the finger rest 56a rotates around the elongated hole 55c as a fulcrum, passes through the escape hole 34a, and passes through the case body. It moves to the lower side of the bottom plate 34 of 30.

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 portion of the central hole A1 which is in contact with the inclined surface 54c of the support portion 54 moves over the convex portion 54a and moves to the inclined surface 54b side. When the edge portion moves toward the inclined surface 54b, the support portion 54 slightly bends inward, so that the edge portion 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 abuts on the edge of the escape hole 34a of the bottom plate 34, thereby restricting the rotation of the lock lever 56. .

As described above, in this embodiment, the lever support portions 55 arranged opposite to each other are integrally provided on the ring-shaped holding portion 51, so that the lever support portion 55 is displaced from the central portion of the holding portion 51. I did it. Therefore, as compared with the above-described embodiment, the lever support portion 55 does not get in the way when the finger rest 56a is pushed in to release the lock, so that the lock can be easily released.

[Effect of device]

 As described above, according to the disc housing case of the present invention, when the disc is locked to the case body side, at least a part of the edge portion of the center hole of the disc is elasticized by pushing the center portion of the disc. The engagement holding member having a force engages and holds, and at the same time, the engaging portion of the lock lever engages with the edge portion of the center hole facing each other on the engagement holding side. On the other hand, when the disc is unlocked from the case body side, the lock lever is rotated to release the engagement state by the engagement portion. As a result, the reaction by the engaging portion acting on the engagement holding member does not work, so that the locked state of the central portion of the disk is released. Therefore, the disc can be locked and unlocked with respect to the case body side by a one-touch operation.
