DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a disk magazine used for a disk player with a disk changer.

(Prior Art) A conventional disk magazine 1 is shown in a partially cutaway perspective view in FIG. 9, and a cross-sectional view taken along a line XX in FIG. The U-shaped portions 4, 4 are formed by the partition plate 3 by the number of trays 5 stored.

The tray 5 to the normal mounting the disk D ₁ of the outer diameter (e.g. 12cm, as shown by a perspective view in FIG. 7, as shown in perspective in FIG. 8, the disk loading recess 6, the information of the disk D ₁ A hole 7 for reading, etc., and left and right convex portions 8, 8 are formed, and the convex portions 8, 8 are engaged with the U-shaped portions 4, 4, and the tray 5 is stored in the magazine 1.

Inner dimension L between the left and right partition plates 3 and 3, because it is smaller than the outer diameter A ₁ of the disc D _1, left and right portions of the disk D ₁ sounds to protrude slightly out of the dimension L hand,
In the state of being stored in the magazine 1, the storage positions of the tray 5 and the disk D _{1 in} the vertical direction are restricted except for the left and right portions of the disk D ₁ in the U-shaped portions 4, 4.

(Problem devised to be Solved) Recently, (those of example 8 cm) diameter disk shown in FIG. 11 of smaller diameter than the disc D ₁ is are being used,
To accommodate the conventional Magasin 1, only置凹portion 9 mounting disc as a longitudinal front view in FIG. 12 in accordance with the diameter of the disk D ₂ is formed on the small diameter, other dimensions are the disk D ₁
Tray 10 formed in the same manner as the tray 5 for use.

However, in the tray 10, left and right portions of the disk D ₂ of the small diameter can not be removed completely in a U-shape portion 4, 4, of the small-diameter disk D ₂ by the left and right partition plates 3 in the vertical direction The storage position cannot be regulated.

Therefore, another tray immediately above the stored tray 10
If there is no 10 or if the storage position is not the top row,
Vibration or the like disk D ₂ of the small diameter it may jump out置凹portion 9 mounting disk.

Although illustration is omitted in order to prevent such a danger, if the partition plate is made longer than the above-described example, the left and right widths of the thick portion (the left and right convex portions 8, portions inside the 8) of the tray become shorter. The strength of the tray decreases.

If the thickness of the tray is made larger than that in the above-described example in order to prevent the strength of the tray from decreasing, the thickness of the magazine itself increases, the disk player becomes large, and handling becomes inconvenient.

An object of the present invention is to solve such a problem of the conventional magazine and to provide a disk magazine designed so that the storage position of a small-diameter disk is regulated reliably.

(Means for Solving the Problems) In the disk magazine of the present invention, a plurality of trays on which disks are mounted are stored in the magazine in a substantially horizontal manner, and the trays are vertically stacked and stored in the magazine. In the disk magazine of the structure to be pulled out, it is provided on a tray of a disk holding member which is formed so as not to open and operate to hold the disk outside the magazine,
At the position where the magazine is stored in the tray, the clamping member by the magnet is used to close the disk clamping member, thereby clamping the disk. It is provided on the member and the magazine.

In the storage position, the holding member side member and the magazine side member do not contact each other.

(Operation) Since the disk holding member is opened outside the magazine, the mounting and dismounting of the disk from the tray outside the magazine can be performed without any trouble.

At the position where the magazine is stored in the tray, the disk holding member is closed by the attraction action of the magnet between the holding member side member and the magazine side member, and the disk is held by this. No special operation is required to maintain it.

Further, since the holding member side member and the magazine side member are configured so as not to be in contact with each other at the storage position, the operation of pulling out and inserting the tray from the magazine can be performed smoothly with little resistance.

(Embodiment) Next, an embodiment of the present invention will be described with reference to the drawings.

FIG. 4 shows an exploded perspective view of the tray 11, and FIG. 5 shows a partially cutaway perspective view of the magazine 12 in a state where the tray is stored.

The tray 11 has left and right convex portions 13 and 13 and a small-diameter disk D _2.
There are provided a disc mounting recessed portion 14, a hole 15, a left and right spring groove 16, a fulcrum pin 17, and a spring locking pin 18 on which a disk can be mounted.

The disk holding member 19 includes a pin hole 20 at the center, a holding portion 21 at one end, and a holding member side member 23 and a spring locking hole 24 each having a magnetic body 22 attached to the other end. The end of the tension spring 25 which is formed, fits the pin hole 20 into the fulcrum pin 17 and is housed in the spring groove 16 is connected to the spring locking pin 18 and the spring locking hole.
24, the holding member side member 23 is
The left and right disk holding members 19 are biased so as to rotate toward the center of 14.

The holding portion 21 is the largest diameter portion (diameter) of the disc mounting recess 14.
Substantially above are located, form a clamping portion 21, because it is made in the front view wedge having an inclined surface 21a on the lower surface as in FIG. 2, the placed right and left of the disk D ₂ By pushing the upper corner downward, it is securely held on the tray 11.

Reference numeral 26 denotes a retaining ring fitted to the fulcrum pin 17 and the spring locking pin 18 for preventing the disc holding member 19 and the tension spring 25 from coming off.

On the left and right side plates 27, 27 of the magazine 12, a plurality of U-shaped portions 29 are formed by a partition plate 28, and the disk holding member 19 of the tray 11 is formed so as to pass through the U-shaped portion 29,
A permanent magnet 30 is attached to the side plate 27 in each of the U-shaped portions 29 to form a magazine side member 31.

When the tray 11 is stored in the magazine 12, the magnetic body 22 of the holding member side member 23 of the disc holding member 19
The sucked by the permanent magnet 30 of the magazine member 31 (not in contact), sandwiching section 21 has a structure for holding the outer periphery of the disc D _2.

 Next, the operation will be described.

As shown in FIG. 1, when the tray 11 on which the disk D ₂ is placed is stored in the magazine 12, the magnetic body 22 provided on the holding member side member 23 of the disk holding member 19 of the tray 11 The disk holding member 19 is attracted by the permanent magnet 30 of the magazine side member 31 provided in the U-shaped portion 29 of the magazine 12, so that the disk holding member 19 rotates clockwise around the fulcrum pin 17 against the tension spring 25. to those of the right and respectively rotated counterclockwise to clamp the disc D ₂ from the left and right sides.

Since the holding portion 21 is provided with an inclined surface 21a as shown in FIG. 2, the disk D ₂ is held in the left and right directions, and is pressed downward to simultaneously regulate the position in the left and right and height directions. .

The clamping portion 21, or kicking affixed elastic material, or, a disk clamping member 19 itself, since the formed by a resilient material, the disc D ₂ which is held it is not hurt.

Then, when the tray 11 is pulled out of the magazine 12, as shown in FIG. 3, the attracting action between the permanent magnet 30 provided on the magazine 12 and the magnetic body 22 of the disk holding member 19 disappears.
The disc holding member 19 rotates in a direction in which the left and right holding portions 21 are separated from each other by the tensile force of the extension spring 25.

This clamping portion 21 away from the disk D _2, the disk D ₂ on the disk loading recess 14 is in a free state.

Even if the disk D ₂ is not placed on the tray 11, the disk holding member is provided on the stopper 32 provided on the tray 11.
As a result, the holding member side member 23 of the disk holding member 19 does not project outward from the left and right convex portions 13 of the tray 11.

Accordingly, even when the disc D ₂ is not placed, the clamping member side member 23 is positioned in the lateral direction inside the convex portions 13, the magnetic body 22 to the permanent magnet 30 of the magazine 12 is not always in contact, the tray 11 The operation of putting in and out is smooth with little resistance.

Further, since the left and right magnetic bodies 22 are equally attracted by the left and right permanent magnets 30, the tray 11 does not shift to the left and right in the magazine 12, and the resistance when the tray 11 is taken in and out is reduced.

As described above, the tray 11 stored in the magazine 12
Disk D ₂ of the small diameter of the upper, and positional regulation by the lateral and vertical direction can nip, it becomes resistance decreases smoothly out operation from the magazine 12.

Moreover, it can be used the conventional size of the tray for mounting the disk D ₁ of the conventional outer diameter in the magazine 12 as shown in FIG. 5, one of the magazines, two different outer diameters of the disc D ₁ and common to D ₂ there is an effect that can be used.

The tray 33 of the second embodiment, shown in a plan view in FIG. 6, has left and right disk holding members 34 formed integrally with a tray body 35.

That is, the vicinity of the center of rotation of the disk holding member 34 is supported by the tray main body 35 by the elastic supporting portion 36.

When the tray 33 is pulled out of the magazine 12, the disk holding member 34 is kept at the non-holding position as shown in FIG.
The magnetic body 22 is sucked in the direction of the arrow C by 30 and the support portion 36
The deflection in the arrow line D direction, the disc clamping member 34 will support the optical disc D ₂ on置凹portion 14 mounting the disk rotates in the arrow line E direction.

According to this embodiment, the same effect as that of the first embodiment can be obtained, the number of parts is reduced, furthermore, no assembling work is required, and the synthetic resin can be molded by one molding so that the manufacturing cost can be reduced. There is also an effect that can be reduced.

(Effects of the Invention) Since the disk magazine according to the invention is configured as described above, in a state where the tray is inside the magazine, the disk holding member is attracted by the magnet between the holding member side member and the magazine side member. The closing operation causes the disk holding member to hold the disk, and the position of the disk is regulated in the magazine in both the surface direction and the thickness direction so that the disk does not fly out even if the magazine vibrates.

Both the small-diameter disk tray and the normal-size disk tray can be housed in the same magazine, which is convenient for use and convenient in design and manufacture.

Then, when the tray is pulled out of the magazine, the magnet holding member and the magazine side member lose their attraction action and the disc holding member is separated from the disc, so that there is no hindrance to the loading operation.

When the tray is stored in the magazine, these members are configured so that the holding member side member and the magazine side member do not contact with each other, so that the tray can be smoothly pulled out and inserted from the magazine with little resistance. It was decided to be.
