However, in this disk cartridge, if the upper case and the lower case are individually fused, and there is a slight displacement at the joint, a step is formed on the outer periphery of the case, especially 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 to the assembly process after the case is formed. The assembly in the automatic assembly line is troublesome, the production cost is high, the number of parts increases, and there is a limit to the cost reduction.When connected at the hinge, the hinge does not bend properly and the product expands as a product. A gap is likely to be formed near the hinge part, and furthermore, only at the welded parts at the four corners of the case, the adhesive strength is weak and a gap due to warpage is created, which is a problem.
Since the upper and lower cases are formed as an integral unit, the case is urged to return to the open shape as it was when it was formed. I couldn't improve her sex. The present invention is intended to eliminate these conventional disadvantages, and is assembled without generating a gap near the hinge portion of the case, has a good appearance, has a high commercial value, and has an automatic assembly line for producing a disk cartridge. Easy to assemble,
It is an object of the present invention to provide an inexpensive disk cartridge with a simple configuration that can significantly reduce production costs by greatly improving production efficiency and reducing the number of parts.
