Description

[Detailed explanation of the idea] [Industrial application field]

The present invention relates to a disk magazine, and particularly to a disk magazine that stores a plurality of disk-shaped media such as optical disks in a stacked manner.

[Summary of the idea]

In the present invention, disk grooves are formed in each of a pair of side walls integrally formed on the bottom plate, and a guide member having an insertion guide opening is arranged on the disk insertion side between the side walls. The disk is inserted between a pair of side walls while being guided, and the disk is held in the magazine by a disk groove.

[Conventional technology]

In an optical disc player equipped with an autochanger, a plurality of optical discs are stored in a magazine, and the discs are selectively pulled out and mounted on the player. As a magazine used in such an autochanger, a magazine is used in which a storage space for each optical disk is partitioned by a partition plate. Such a magazine has the disadvantage that it has a large number of parts, especially due to the partition plate. Therefore, for example, as proposed by the applicant of the present invention in U.S. Pat.

[Problem that the invention attempts to solve]

However, in such a conventional disk magazine, if the optical disk is not correctly positioned and inserted into the magazine, the left and right disk grooves will be engaged with the disk grooves at different levels. Therefore, in such a case, there is a possibility that the optical disk will not be inserted into the magazine correctly, or that the optical disk will be deformed. The present invention was devised in view of these problems, and its purpose is to provide a disk magazine that has a reduced number of parts, allows reliable insertion of disks, and does not damage the disks. It is something to do.

[Means to solve the problem]

The present invention includes a bottom plate having a pair of side walls in which mutually symmetrical disk grooves are formed, a guide member having a disk insertion guide opening disposed on the disk insertion side between the pair of side walls, and one side wall. a leaf spring held by a holding part formed on the outside of the
A disk push-out lever disposed on the outside of the other side wall; an outer casing having an insertion hole into which the push-out portion of the disk push-out lever is inserted; and an insertion hole into which the operating portion of the disk push-out lever is inserted. The present invention relates to a disk magazine having a cover formed therein.

[Effect]

Therefore, according to the present invention, the disk is held by the disk groove, which eliminates the need for a partition plate within the magazine, making it possible to reduce the number of parts. Moreover, since the disk is inserted while being guided by the guide opening disposed on the disk insertion side, it is possible to prevent the disk from being inserted at the wrong level.

【Example】

The present invention will be explained below with reference to an illustrated embodiment.
FIG. 1 shows a disk magazine according to an embodiment of the present invention, and this disk magazine is adapted to be installed in a disk player equipped with an automatic changer. This magazine includes a low plate 10 made of a synthetic resin molded body, and a pair of left and right side walls 11 and 12 on the bottom plate 10.
are attached to each other. These side walls 11,
A plurality of disk grooves 13 are provided on the inner circumferential surface of each disk 12.
is formed. Further, a horizontally elongated guide member 14 is arranged between the side walls 11 and 12 on the disk insertion side. As shown in FIG. 4, this guide member 14 is provided with a plurality of insertion guide openings 15.
As shown in FIG. 5, the opening 15 is wider at the middle than at both ends. Further, a holding portion 16 is formed on one side wall 11, and this holding portion 16 allows the leaf spring 1 to be
7 is gaining popularity. The leaf spring 17 is divided into a plurality of parts by a slit 18, and each part is adapted to lightly push the optical disk. On the other hand, a disk push lever 21 is arranged on the outside of the side wall 12 on the opposite side. That is, the outer casing 19 is attached so as to cover the upper side of the side walls 11 and 12, and the cover 20 is attached to one side of the outer casing 19, so that the side wall of the outer casing 19 and the cover 20 are attached to each other. A disk push-out lever 21 is disposed between them. The push-out portion 22 of this lever 21 is attached to the outer casing 19.
It faces into the magazine through the insertion hole 23 of the side wall 12 and the insertion hole 24 of the side wall 12. The operating portion 25 of this lever 21 is connected to the insertion hole 2 of the cover 20.
6 and is exposed to the outside. As shown in FIG. 2, such a magazine 10 is arranged to face a disk player. And this magazine 10 is 10
The optical disks 30 are stored in a stacked manner, and a pair of pull-out rollers 31 and 32 for pulling out the optical disks 30 are arranged at the front of the magazine. Therefore, when the pull-out lever 21 is moved forward by operating the operation part 25 exposed from the insertion hole 26 of the cover 20 on the outside of the magazine, the push-out part 22 of this lever 21 moves the selected optical disk 30. As a result, the optical disk 30 protrudes forward while being guided by the disk grooves 13 of the pair of side walls 11 and 12. The optical disk 30 thus pushed out passes through the insertion guide opening 15 of the guide member 14, and its leading end is gripped by a pair of pull-out rollers 31, 32. and rollers 31,3
2 rotates, the optical disk 30 is pulled out from the magazine. Note that at this time, a presser roller 33 is used to prevent the optical disk 30 from moving upward. As the optical disk 30 is pushed out by a predetermined amount, the spindle motor 3
When the optical disc 30 is positioned above the turntable 35 of No. 4, in this state, the optical disc 30 is lowered by a lowering means (not shown) and is received by the turntable 35, so that the disc 30 is placed on the disc player. will be installed. According to such a disk magazine, since the disk grooves 13 are formed in each of the pair of side walls 11 and 12 shown in FIG. This makes it possible to reduce the number of parts. Further, since the outer peripheral surface of the optical disk 30 is pressed down by the spring 17 disposed on the outside of the side wall 11, it becomes possible to stably hold the optical disk 30. Also, when pulling out the optical disk 30,
It passes through the opening 15 of the guide member 14, but since the opening 15 is wider at the center than at both sides, as shown in FIG. This avoids damaging the surface on which the signal is being recorded. As shown in FIGS. 3 and 6, the rollers 31 and 32 for pulling out the optical disk 30 passing through the guide member 14 have larger diameters at both end portions than at the middle portion. These rollers 31 and 3
2. That is, the rollers 31 and 32 can pull out the optical disc 30 without almost contacting the surface of the optical disc 30. Therefore, according to this configuration,
It is also possible to prevent damage to the optical disk 30 caused by the rollers 31 and 32. When the optical disc 30 is returned to the magazine after playing, the pair of rollers 31 and 32 rotate in the opposite direction to when the optical disc 30 is pulled out, thereby pushing the optical disc 30 into the magazine. It will be crowded. Also in this case, roller 3
Due to the shapes of 1 and 32, the disk 30 will not be damaged. Also, the opening 15 of the guide member 14
is prevented from coming into contact with the surface of the optical disk 30. Further, the opening 15 of the guide member 14 reliably prevents the optical disk 30 from being engaged with the disk grooves 13 of the left and right side walls 11 and 12 at different levels, thereby preventing the optical disk 30 from being engaged with the disk grooves 13 of the left and right side walls 11 and 12.
It becomes possible to store 0 correctly.

[Effect of the idea]

As described above, in the present invention, since the disk is held by the disk groove in the pair of side walls, there is no need to arrange a partition plate inside the magazine, thereby reducing the number of parts. It becomes possible to achieve this goal. Moreover, since the disk is guided by the insertion guide arranged on the disk insertion side of the pair of side walls, it is possible to prevent the disk from being inserted into the disk groove of the pair of side walls at a different level. Therefore, it is possible to correctly store the disk in the magazine, and it is also possible to prevent the disk from deforming.
