Abstract

PURPOSE:To reduce the number of assembling processes with the assembling of one process and to attain the automatic assembling by dividing a disk cartridge enclosure to one surface or other surface and sliding one surface or other surface to two sides contacting to this. CONSTITUTION:A disk cartridge enclosure is divided into a sliding cover 1 composed of two surfaces and a lower box 2 composed of other surface excluding two surfaces, and the sliding cover 1 is assembled by sliding guide grooves 3 and 3' held by the lower box 2. By other method, the cartridge enclosure is divided into a sliding cover 4 composed of one surface and a lower box 5 composed of other surface excluding one surface, the sliding cover 4 is slit to guide grooves 6 and 6' held by the lower box 5 and assembled by one process. The number of the assembling processes of the cartridge to house the disk-shaped recording medium is reduced and an automatic assembling can be executed.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a disk cartridge that accommodates a disk-shaped recording medium.

[Conventional technology]

A conventional disk cartridge is composed of an upper half and a lower half as shown in FIG. The disc-shaped recording medium 13 housed in a rotatable manner and the upper and lower pieces are integrally provided so that the cross section has a substantially double-shaped cross section, and are inserted into the outside of the upper and lower halves from one edge side of the cartridge housing. a shutter that is movably attached along one end edge and provided using the elasticity of a spring so as to freely open and close the head insertion hole on at least one of the upper or lower pieces; By providing the information recording and reproducing apparatus with a mechanism that automatically opens and closes the shutter when the disc cartridge is attached or removed, the disc cartridge becomes extremely user-friendly for the user. However, from the manufacturer's perspective, incorporating minute spring parts into the cartridge, screwing or gluing the upper and lower halves, and screwing the shutter increases the number of assembly steps. Undesirable. Especially when considering automatic assembly, it is not easy for automatic machines to handle springy parts.

[Summary of the invention]

According to the present invention, the number of assembly steps can be reduced by assembling the housing by dividing the disk cartridge housing into one or two sides and the other side, and sliding the one or two sides to the two adjacent sides. This is a decrease in

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows a first embodiment of the present invention, and for the sake of clarity, minute parts inside the car IJ joint are omitted. The cartridge case is divided into a slide lid 1 made up of two sides of the cartridge case and a lower box 2 made up of the other side except for the two sides. ′ can be assembled by sliding. As shown in part A (1), the guide groove has a convex shape on the slide lid side, and the guide groove on the lower box has a concave shape on each side where the slide lid touches.
As shown in (2), there is also a tsuta/A9 part shape formed from one end of the side to the other end, with the slide lid side having a concave shape and the lower box side having a convex shape.

A second embodiment of the present invention is shown in FIG. The cartridge case is divided into a slide lid 4 which is made up of one side of the cartridge case, and a lower box 5 which is made up of the other side excluding the above-mentioned negative side. ′
It can be assembled by sliding.

As a third embodiment, the slide lid 1' shown in FIG.
In order to prevent the slide lid 1' from moving in the direction of the guide groove 7 when the lower box 2' is assembled, a lock pawl 8 with a notch is provided as shown in FIG. 3(1). (2) shows the slide lid 1' being inserted into the lower box 2' along the guide groove.
), the cut of the lock pawl 8 is the critical part 9 of the lower box 2'.
It seems to be caught on.

〔Effect of the invention〕

As explained above, by separating the disk cartridge into the sliding lid and the lower box and inserting the sliding lid along the guide groove of the lower box, the temporary fixing of springs and numerous screws that were conventionally required can be omitted. Therefore, the disk cartridge can be assembled extremely easily, and automatic assembly is also easy.
