Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a disk storage case that accommodates a large number of compact audio disks and video disks.

[Summary of the idea]

A pair of opposing guiding grooves formed on each disk holding surface of the shelf-shaped disk storage space allows
The disc pressing part of the disc pushing member is slid and guided, thereby preventing a gap from being formed between the pushing member and the disc holding surface, and thereby ensuring that the disc is ejected.

[Conventional technology]

A storage case (magazine) that stores a large number of compact audio discs or video discs is used in auto-change type players for continuous playback. In addition, such a storage case can store a large number of disks in a small space, so
It can also be used as a storage box for disks.

In general, this type of disk storage case has a structure in which a case 1 having an opening on the front surface 1a has a number of shelf-like partition plates 2 spaced apart by the thickness of the disks 3, as shown in FIG.

A push-out member 8 that can be operated in the disk ejection direction is in contact with the periphery of the stored disk 3, and the push-out member 8 can push the disk 3 toward the front surface 1a and take it out from the case 1. . The extrusion member 8 is connected to an extrusion pawl 14 protruding from a slit 16 in a side plate 15 on the side surface of the case via a sliding plate 9, and can be extruded by operating the extrusion pawl 14 with a finger or the arm of an autochanger. Member 8 can be actuated.

As shown in the main part sectional view of FIG. 8, the extrusion member 8 is a flat plate member located almost on the same plane as the disc 3 to be accommodated, while the corresponding edge of the disk 3 is shown in the detailed sectional view of FIG. As shown, it has a tapered shape.

[Problem that the invention attempts to solve]

For this reason, as shown in FIG. 9, when pushing out the disk 3, the disk 3 and the push-out member 8 run out of plane, and the disk 3 gets stuck in the gap above or below the push-out member 8. I had to put it away. In such a state, it becomes difficult to remove the disk 3, and the recording surface of the disk may be scratched.

The purpose of the present invention is to solve this problem and enable reliable disk ejection.

[Means for solving problems]

As shown in FIG. 1, each disk storage space is partitioned by a shelf-like partition plate 2 at approximately the thickness of the disk, and a slide-operated push-out member 8 for pushing out the disk 3 to the outside protrudes from the side of the case. has been done. The portion 8a of each extrusion member 8 that contacts the disk periphery is larger than the interval between the disk holding surfaces forming the disk storage space, and fits into a pair of guide grooves 7 formed on each opposing disk holding surface. guided in the extrusion direction.

[Effect]

Since the structure is such that no gap is created between the disk holding surface of the partition plate and the extrusion member, there is no risk that the edge of the disk will be caught above or below the extrusion member when the disk is ejected.

〔Example〕

FIG. 1 is a perspective view showing an embodiment of a disk storage case to which the present invention is applied.
The front surface 1a of the disc is an opening, and a large number of partition plates 2 are inserted into the front surface 1a at predetermined intervals corresponding to the thickness of the disk. The disk 3 is stored in a storage space formed by these partition plates 2.

FIG. 2 is a horizontal sectional view of FIG. 1 along the partition plate 2, showing the entire plane of the partition plate 2. FIG. The partition plate 2 has a rectangular shape on the front side 1a (introduction part) of the case 1, and a semicircular shape on the rear face 1b side (holding part). Each partition plate 2 has a convex portion that engages with a concave portion formed in the case 1, and is held like a shelf by the engagement of these concave and convex portions. That is, convex portions 2a, 2b, and 2c are formed protruding from the rear circular portion of the partition plate 2 in the insertion direction of the partition plate 2, and these convex portions
The support walls 1c and 1d are formed inside the partition plate 2 so as to partially surround the partition plate 2, and the recesses 4a to 4c formed inside the rear surface 1b of the case 1 are engaged with the support walls 1c and 1d, respectively.

In addition, recesses 4 are provided at both ends of the front surface 1a of the case 1.
d and 4e are formed, and convex portions 2d and 2e formed at both ends of the front end of the partition plate 2 engage with these. Note that each of the recesses 4a to 4e on the side of the case 1 is connected to the partition plate 2.
It is formed in a hierarchical manner corresponding to the layers of .

A pair of horn-shaped hooks 5a and 5b are provided from the rear circular portion of the partition plate 2, and when the partition plate 2 is inserted, the support walls 1c and 1 on the case side are attached.
These hooking claws 5a, 5 are attached to the edges 6a, 6b of d.
b is caught and the partition plate 2 is fixed.

A leaf spring 10 having both ends fixed is attached to the inner surface of the other side surface 1f of the case 1, and a convex portion 10a at the center thereof presses the housed disk 3 to the opposite side. Since the concave portion 10a of the leaf spring 10 is slightly biased toward the take-out side (toward the front surface 1a of the case 1) than the center position A of the disk 3 housed in it, the disk 3 is pushed against the leaf spring 10. It is held at a fixed position in the case 1 unless it is pushed out.

A rim 2f is formed on the periphery of the partition plate 2, and is continuous to the rim 2f on the entire front and back surfaces.
A rib 12 is formed toward the long hole 13 in the center. Ribs 12 on the rectangular portion of the partition plate 2 that are connected to the entire surface 1a (opening) of the case 1 extend parallel to the front surface 1a, and ribs 12 on the rear circular portion extend radially.
The ribs 12 extending in parallel have a tapered shape in which the height gradually decreases as the ribs 12 go inward from the rim 2f at the peripheral edge of the partition plate 2. Similarly, the radially extending ribs 12 are also tapered. Therefore, the substantial disk supporting surface of the partition plate 2 is a V-shaped concave surface at the square portion, and a mortar-shaped concave surface at the rear circular portion.

A guide groove 7 is formed in a part of the rear circular portion of the partition plate 2 in the direction in which the disk 3 is inserted and removed, and is surrounded by ribs 7a. As shown in the perspective view of the main part in FIG. 3 and the sectional view of the main part in FIG. is embedded in. The extrusion member 8 is connected to a sliding plate 9 that is slidably held on the side surface of the case.
By holding it and pushing the edge of the disk 3, the disk 3 can be ejected from the front surface 1a.

The push-out pawl 14 projects from a slit 16 formed in a side plate 15 that slides and holds the sliding plate 9 on the side surface 1e of the case 1, and inserts a finger or the arm of the autochanger here. It can be hooked and operated. A detection claw 17 provided on the sliding plate 9 in parallel with the push-out claw 14 is a claw for detecting the disc ejection position, that is, the re-storage position when the storage case 1 is attached to the autochanger player. be.

As clearly shown in the sectional view of FIG. 4, the push-out member 8 has a disk pressing portion 8a wider than the height of the disk storage space, and both upper and lower ends of the disk pressing portion 8a are fitted into the grooves 9. Therefore, since no gap is formed between the substantial disk holding surface formed by the ribs 12 of the partition plate 2 and the extrusion member 8, the edge of the disk is not bitten, and the disk can be securely held. A pushing motion is obtained.

Furthermore, as clearly shown in the perspective view of the push-out member 8 in FIG.
b is cut in the tangential direction of the disk 3, and a V-groove 18 is formed there. Since the end face of the disk is pushed out by the push-out member 8 while being inserted into the V-groove 18, no misalignment occurs between the disk 3 and the push-out member 8 during push-out, and a more reliable disk push-out operation can be obtained.

As shown in Modifications A to C in FIG. 6, the shape of the disk contact surface 8b of the extrusion member 8 may be one in which an arcuate groove 18a is formed as in A, a flat one as in B, or a shape in C. A dish-shaped groove 18c as shown in
It may be formed by

[Effect of idea]

As described above, in the present invention, the disk pressing part 8a of the push-out member 8 is slid along the upper and lower opposing grooves 7 formed on the disk holding surface to push out the disk 3. Since there is no gap between the disk holding surface and the disk holding surface, the edge of the disk 3 is not bitten, and the disk can be ejected reliably.
