BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a disk cartridge in which a disk-shaped medium such as a flexible disk and a hard disk is rotatably stored in a case.

[0002]

2. Description of the Related Art Generally, a flexible disk or a hard disk as an information recording carrier is easily damaged,
Since it is easy for dust and dirt to adhere, it is handled as a disk cartridge stored in a case and is configured to be easily set in a recording / reproducing device. Conventionally,
In this type of disk cartridge, the upper case and the lower case are separately formed, and a disk-shaped medium is mounted inside and the upper case and the lower case are fused.

[0003]

However, in this disk cartridge, when the upper case and the lower case are fused, if there is a slight displacement at the joint, a step occurs on the outer periphery of the case, particularly on the label area. , The appearance of the case deteriorates and the product value decreases, and the upper and lower cases are temporarily assembled during the transportation process to the assembly process after the case is formed. This is problematic because the assembly on the line is troublesome, the production cost is high, and the number of parts increases, which limits the cost reduction. Also, when the upper and lower cases are integrally molded with the hinge part,
When the upper and lower cases are overlapped and assembled, welding is difficult due to the return action due to elasticity, and there is a risk of displacement of the welding position, which is inconvenient in working. The present invention is intended to eliminate these conventional drawbacks, so that the upper and lower cases integrally formed at the hinge portion can be easily incorporated in an automatic assembly line, and the welding operation can be performed accurately and easily. Improvement and
It is an object of the present invention to provide an inexpensive disk cartridge having a simple configuration and capable of reducing costs by reducing the number of parts.

[0004]

SUMMARY OF THE INVENTION The present invention provides a disk cartridge in which a disk-shaped medium is rotatably housed in a case composed of an upper case and a lower case, and the upper and lower cases are welded and connected. A hinge part is provided in the label area part 5 with the lower case, and the upper case and the lower case are integrally connected so as to be freely bendable. A temporary fixing boss is protruded, and the temporary fixing boss is fitted to form a temporary fixing structure.

[0005]

The upper case 1 and the lower case 2 of the disc cartridge are formed integrally with the label area 5 at the hinge 3 so that the upper case 1 is unfolded in the assembling process without being temporarily assembled. After being bent from the hinge portion 3 and superimposed on the lower case 2 to engage the boss portions 11 and 12 for temporary fixing, the welding process is performed by welding at the welding portions 13 and 14 in the welding process, thereby greatly increasing productivity. Can be improved. At this time, the upper and lower cases 1 and 2 are held in a bent state by the hinge portion 3, and the lifter 15 in the case is also transported in a bent state, and the disk-shaped medium 6 and other liners are incorporated in the medium storage section 16. Thus, the upper case 1 is overlapped with the lower case 2 and the boss portions 11 and 12 are snap-engaged to perform a temporary fixing operation.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to FIGS. 1 to 5. In a disk cartridge for rotatably storing a disk-shaped medium 6 in a case including an upper case 1 and a lower case 2, an upper case 1 is provided. and the label area 5 of the rear edge of the lower case 2, thereby integrally interconnects the upper case 1 and the lower case 2 the hinge portion 3 is provided, the outer peripheral side surface portion 3 ₁ of the hinge portion 3 is formed flat The disk cartridge is provided with boss portions 11 and 12 for temporary fixing protruding near the welded portions 13 and 14 of the upper and lower cases.

In this case, the case is one in which a lifter 15 is integrally formed in a media accommodating portion of the lower case 2, and the lifter 15 and the hinge portion 3 are held in a bent state. It is preferable to use a disk cartridge provided with the bosses 11 and 1.
Reference numeral 2 denotes a snap-fitting structure, and one or two or more snap-fitting structures are provided in the upper case 1 and the lower case 2 so as to face corners of the case outside the disc area not on the hinge side.

The hinge part 3 includes upper and lower cases 1,
2 is formed integrally with the inner wall surface of the label area 5 by a pair of V-grooves 4 and 4, and the upper case 1 and the lower case 2 are integrally formed with the side walls to form a U-shaped cross section. It has been, are conveniently become Toriatsukaieru so without the outer circumferential surface 3 ₁ of the label area 5 becomes flat, yet also temporarily assembling the conveyance to the assembly process. The V-grooves 4 are arranged in parallel with the edge of the label area 5 and are provided separately at inner corners of the upper and lower case side walls. Is formed so as to be simple, but if necessary, V
The grooves 4 may be connected to each other by providing a pair of grooves or one groove at the center.

In the figure, reference numeral 7 denotes a window for inserting a recording / reproducing head, and 8
Is provided so that it can be opened and closed by a shutter. Reference numeral 9 denotes a sliding sliding area in which a shutter is fitted by a concave sliding surface.
Reference numeral 10 denotes a disc hub fitting hole.

[0010]

The present invention is directed to a disk cartridge for rotatably storing a disk-shaped medium in a case composed of an upper case and a lower case, wherein a hinge portion is provided at a label area of the upper case and the lower case. The upper case and the lower case are integrally formed, and a temporary fixing boss is protrudingly provided at a corner of the case outside the disc area on the side of the upper and lower cases which is not on the hinge side. The upper and lower cases are welded and joined after stopping, so that the transfer from the molding process to the assembly process can be performed efficiently without temporary assembly, and when the upper and lower cases are joined, the upper and lower cases are overlapped. Can be easily fixed, and the welding work can be performed accurately and efficiently, making it easy to incorporate into the automatic assembly line.The productivity can be greatly improved, and the cost can be reduced by reducing the number of parts. The molding process of the base and lower case can be assembled without producing any level difference in the label area of the case, and the appearance is good, and the simplicity of the assembling work can improve accuracy and facilitate mass production. Has the effect.
