DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a disk cartridge for storing recording disks such as optical disks and magneto-optical disks, and more particularly to a disk cartridge which can be mounted on a recording / reproducing apparatus while the recording disks are stored in a case body. The present invention relates to a disk cartridge that can take out the recording disk from a case body and mount it on a recording / reproducing apparatus as a recording disk alone.

[0002]

2. Description of the Related Art Various types of disk cartridges for recording or reproducing information while a recording disk is housed in a case body or a recording disk taken out of the case body is mounted alone in a recording / reproducing apparatus have been proposed. ing.

[0003]

In a conventional disk cartridge of this type, when the recording disk is taken out of the case body, the recording disk is not supported, so that the recording disk is unexpectedly dropped, resulting in drop damage or damage. There were drawbacks.

[0004] It is an object of the present invention to solve the above-mentioned drawbacks of the prior art and to provide a disk cartridge which is easy to handle and free from dropping scratches and damage.

[0005]

In order to achieve the above object, the present invention provides a case body having a head insertion port and a spindle insertion port on at least one plane, and a disk outlet on one side. A shutter for opening and closing a head insertion opening of the case main body, a recording disk such as an optical disk rotatably stored inside the case main body, and a rotatable support at one end of a disk outlet of the case main body. A closing member that opens and closes the disk outlet, and prevents the recording disk from dropping from the disk outlet when the disk outlet of the case body is opened by the closing member. A falling-off preventing means including a support arm and the like is provided on the closing member.

The present invention is configured as described above,
When the disk outlet of the case main body is opened by the closing member to take out the recording disk from the case main body, the recording disk can be prevented from dropping unexpectedly by the falling-off preventing means provided on the closing member. There will be no drop damage or damage.

Further, since the closing member is rotatably supported by the case body and the falling-off preventing means is attached to the closing member, the closing member and the falling-off preventing means do not separate from the case body. And loss prevention means are not lost.

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, an embodiment of the present invention will be described with reference to the drawings. 1 is a plan view of an unused disk cartridge in which a recording disk is stored in a case body, FIG. 2 is a cross-sectional view taken along the line II in FIG. 1, FIG. 3 is a side view of the disk cartridge, and FIG. FIG. 5 is an enlarged plan view of a connecting portion between the cover member and the support arm, FIG. 6 is a plan view of the support arm, FIG. 7 is a side view of the support arm, and FIG. FIG. 4 is a partial plan view showing a state where a recording disk is taken out of a case main body.

The disk cartridge according to the present invention mainly comprises a case body 1, a cover member 2, a support arm 3, a recording disk 4 such as an optical disk, and a shutter 5.

The case body 1 is formed by combining an upper case half 1a and a lower case half 1b (see FIG. 2). As shown in FIG. 1 and FIG. An opening formed by connecting the insertion port 6 and the spindle insertion port 7 is formed. As shown in FIGS. 2, 3 and 8, a disk outlet 8 is provided on one side of the case body 1. As shown in FIG.

The cover member 2 opens and closes the disk outlet 8, and as shown in FIGS. 1 and 3, the base end 2a of the lid member 2 is pinned by a pin 9 to one end of the disk outlet 8. Is rotatably supported. This base end 2
A disk receiving portion 10 is provided from a to the free end side,
As shown in FIG. 2, a substantially V-shaped support groove 11 is formed on the inner surface of the disk receiving portion 10. As shown in FIGS. 1 and 2, the disk outlet 8 is provided on the side opposite to the side on which the shutter 5 is mounted.

A support arm 3 is rotatably supported at a free end of the lid member 2 via a pin 12. As shown in FIG. 5, a coil spring 13 is interposed at a connection portion between the lid member 2 and the support arm 3, whereby the support arm 3 is elastically biased toward the lid member 2.

The free end side of the support arm 3 is divided into two as shown in FIG. 6, one of which is an upward first pin 14 serving as a shutter holding part, and the other is a downward second pin 14 serving as a disk holding part. The pin 15 is fixed. As shown in FIGS. 1 and 7, the first pin 14 is in contact with the edge of the shutter 5 and the second pin 15 is in contact with the peripheral edge of the recording disk 4.

As shown in FIG. 2, the shutter 5 includes a shutter plate 5a for opening and closing the head insertion port 6 and the spindle insertion port 7, and a slide portion 5b integrally connected to one end of the shutter plate 5a. I have.

In the unused state in which the recording disk 4 is stored in the case body 1, as shown in FIG.
Resiliently contacts the edge of the shutter 5 to maintain the closed position of the shutter 5, and the second pin 15 resiliently contacts the periphery of the recording disk 4. By the elastic contact of the second pin 15, the recording disk 4 is pressed toward the disk receiving portion 10 of the lid member 2, and the peripheral edge of the recording disk 4 is set in the V-shaped support groove 11 as shown in FIG. The recording disk 4 is supported without being in contact with the case main body 1 on both upper and lower surfaces thereof.

When the disk cartridge with the recording disk 4 housed in the case body 1 is inserted into the recording / reproducing apparatus, the shutter 5 slides as shown by the dashed line arrow in FIG. It rotates as shown by the dashed line arrow. By this rotating operation, the second pin 15 is separated from the recording disk 4, and the recording disk 4 becomes rotatable. FIG. 4 shows a state in which the shutter 5 slides to completely open the head insertion port 6 and the spindle insertion port 7.

When the disk cartridge is removed from the recording / reproducing apparatus, the state automatically returns to the state shown in FIGS.

When taking out the recording disk 4 from the case body 1 and mounting it alone on the recording / reproducing apparatus, the recording disk 4 is opened by opening the cover member 2 from the case body 1 as shown in FIG. Can be taken out of the case main body 1 while being supported by the. Then, while the support arm 3 is elastically displaced (rotated), the recording disk 4 is moved.
Can be pulled out from the lid member 2 side in the direction of the arrow and mounted on the recording / reproducing apparatus.

In the above embodiment, the first pin and the second pin are implanted on the free end side of the support arm. However, the free end side of the split support arm is bent to form a shutter holding portion and a disk holding portion. The part may be formed integrally.

[0020]

The present invention has the above-described structure, and when the disk removal opening of the case main body is opened by the closing member in order to take out the recording disk from the case main body, the dropout provided on the closing member is provided. By the prevention means, the recording disk can be prevented from dropping unexpectedly, and the recording disk does not fall or be damaged.

Further, since the closing member is rotatably supported by the case body and the falling-off preventing means is attached to the closing member, the closing member and the falling-off preventing means do not separate from the case body. And loss prevention means are not lost.
