Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a disk device, and more particularly to a disk device which prevents damage to the disk cartridge and the device when inserting and removing a disk cartridge containing a disk.

[0002]

2. Description of the Related Art In a conventional disc device, for example, a slot-in system or a tray system is used as a system for inserting and removing a cartridge (for example, a mini disc) having a built-in disc.

[0003]

However, in the above-mentioned method, when the disk cartridge is inserted into the disk apparatus, the apparatus using the slot-in method has a narrow slot-in insertion port, for example, the front and back sides are inserted in reverse. It is easy to make insertion mistakes such as. Further, even when the tray system is used, there is a drawback that it is easy to mount the disk cartridge on the front or back or front and back.

Therefore, the present invention has been made in order to solve the above-mentioned drawbacks, and prevents damage to a disk cartridge due to erroneous insertion of the disk cartridge,
Further, it is an object of the present invention to provide a disk device that prevents damage to the device.

[0005]

In order to achieve the above object, the present invention provides a notch for ejecting a disc cartridge at an appropriate position of a tray for conveying a disc cartridge containing a disc, and the tray is provided with a disc cartridge. It is characterized in that an accommodating portion to be fitted is provided, and a guide convex portion that engages with a guide concave portion provided on the back surface of the disk cartridge is provided at a predetermined position in the accommodating portion.

Further, a convex portion is provided in a proper place on the casing of the disc device, and a groove for engaging with the convex portion is provided at a required position of the tray so as to prevent the disc cartridge from being erroneously inserted into the casing. It is characterized by

[0007]

Since the tray of the present invention is provided with the storage portion which is shaped to fit with the disk cartridge, the disk cartridge cannot be placed with its front and back reversed. Moreover, since the guide convex portion is provided in the housing portion, the disk cartridge cannot be mounted with its front and back reversed.

Further, since the tray is provided with a groove for preventing erroneous insertion, and a convex portion for preventing erroneous insertion is provided on the housing of the apparatus, the front and back of the disk cartridge are placed in reverse in the storage portion. When trying to store the tray inside the device body in the state,
Since the disc cartridge comes into contact with the protrusion for preventing erroneous insertion provided on the housing, erroneous insertion of the disc cartridge can be prevented, and damage to the disc cartridge and the device can be prevented.

Embodiments 54 Embodiments of the present invention will be described in detail below with reference to the drawings. FIG. 1 is a schematic explanatory view showing a state in which a tray 2 is projected from a casing 1 of a disk device according to an embodiment of the present invention, and FIG. 2 is a rear plan view of a disk cartridge (for example, a mini disk) 3 containing a disk. Is.

First, the structure will be described. The shape of the disk cartridge 3 is different between the front and rear, the front corners are rounded like 3d, and the rear corners are right like 3e.
Further, since the guide concave portion 3a is provided on the back surface, it is possible to distinguish front and back and front and back from the shape. Incidentally, 3f is a shutter portion provided on the disc cartridge 3.

The tray 2 is provided with an accommodating portion 4 on which the disc cartridge 3 is placed, at an approximately central portion thereof, and an outer edge portion 5 having a predetermined wall thickness is provided on a peripheral portion of the tray 2. The inside of the outer edge portion 5 is formed in a shape that fits into the disc cartridge 3. Further, the storage portion 4 of the tray 2 is composed of a support plate 6 provided at the bottom and a recording / reproducing opening 7, and
Are provided on both the left and right sides of the storage unit 4, and the recording / reproducing opening 7 is provided substantially at the center of the storage unit 4. Further, a guide convex portion 8 is provided so as to project on the side of each housing 1 of the support plate 6, and the guide convex portion 8 is formed in the disk cartridge 3
Is formed in a shape that engages with the guide recess 3a on the back surface of the. The guide convex portion 8 may be provided at one place.

At the center of the upper side of the tray receiving port 9 on the front surface of the housing 1, a convex portion 10 is provided vertically downward to prevent erroneous insertion of the disk cartridge 3. Further, a groove 11 for preventing erroneous insertion is provided in the central portion of the outer edge portion 5 of the tray 2 on the housing 1 side, and a storage groove 12 is provided in the front central portion of the outer edge portion 5 of the tray 2. ing. The groove 11 for preventing erroneous insertion and the groove 12 for storage are formed in a shape that engages with the convex portion 10 of the storage port 9 of the housing 1, respectively. Further, notches 13 for taking out the disc cartridge 3 are provided at both left and right ends of the outer edge portion 5. Reference numeral 14 is a group of operation buttons provided on the disk device, and 15 is a display unit such as an LCD.

Next, the operation of this embodiment constructed as described above will be described. The tray 2 is pulled out to the protruding position shown in FIG. 1, and the disc cartridge 3 is placed in the storage portion 4 of the tray 2. At this time, by placing the disc cartridge 3 so that the inner shape of the outer edge portion 5 of the tray 2 and the disc cartridge 3 are fitted to each other, the disc cartridge 3 is placed in the storage unit 4 in a normal state without making a mistake in the front-back direction. it can.

However, as shown in FIG. 3, when the disk cartridge 3 is mistakenly placed upside down in the accommodating portion 4, the guide convex portion 8 is provided on the support plate 6, so that the guide is formed. The convex portion 8 and the surface 3b of the disc cartridge 3
And the end portions 3c of the disc cartridge 3 project upward from the groove 11 for preventing erroneous insertion provided in the outer edge portion 5, so that the front and back sides of the disc cartridge 3 are erroneously placed. Can be found.

Further, when the tray 2 is to be stored in the housing 1 while the disc cartridge 3 is erroneously placed in the storage portion 4 with its front and back reversed, a groove 11 for preventing erroneous insertion is provided.
The more protruding end 3c of the disc cartridge 3 comes into contact with the convex portion 10 provided in the storage port 9 of the housing 1 and the storage operation of the tray 2 is stopped, whereby the erroneous insertion of the disc cartridge 3 can be prevented, It is possible to prevent damage to devices (not shown) and the like in the housing 1.

[0016]

As described above in detail, according to the present invention, in the disc device, by using the tray provided with the accommodating portion having a shape to be fitted with the disc cartridge, the disc cartridge is erroneously placed in the accommodating portion. It is possible to prevent the disk cartridge and the device from being damaged by being placed on the disk. Further, by providing the protrusion or the groove for preventing erroneous insertion, it is possible to prevent erroneous insertion of the disk cartridge before the tray is housed in the main body of the device, and prevent failure of the device.
