In this type of disc player, the player body that rotates and drives one disc to read the music information, etc., and the disc storage case that stores a large number of discs separately are separated. It is provided. When playing a disc, a disc storage case accommodating a large number of discs is attached to the player body.

In a conventional disk storage case of this type, a case body is formed in a box shape, and an opening for inserting and removing a disk is provided on one side surface thereof. On the inner surfaces of both side walls of the case body, a plurality of engaging grooves that horizontally extend from the opening toward the back are formed at predetermined intervals in the upward and downward directions. Then, by inserting a plurality of partition plates into the engagement groove from the opening side of the case body, a disc storage space is formed between the partition plates.

Further, a locking portion is provided inside the case body, and a locking claw that can be engaged with the locking portion is formed on each partition plate. Then, when the partition plate is inserted into the locking groove of the case body, the locking claw engages with the locking portion so that the partition plate is retained and retained at a predetermined position in the case body. Has become.

However, in this conventional disc storage case, great care must be taken when inserting the partition plate into the engagement groove from the opening side of the case body so as to be horizontal to the case body. In addition, this work must be performed for each of a plurality of partition boards. Therefore, it takes time to assemble one disk storage case as a whole, and there is a problem that workability is poor. Further, in this conventional disk storage case, since it is necessary to provide a retaining structure composed of a locking portion and a locking claw, the assembly structure of the partition plate becomes complicated and the manufacturing cost rises. There was also a problem.

In order to solve such a problem, for example, a disk storage case having the structure shown in the microfilm of Japanese Utility Model Application No. 61-73767 (Japanese Utility Model Application No. 62-187494) has been proposed in the past. There is.

[0009]

[Problems to be solved by the device]

 However, in this conventional disc storage case, the support groove and the guide groove must be provided in the disc support block and the guide block at predetermined intervals so as to correspond accurately in the vertical direction. That is, if the support groove of the disk support block and the guide groove of the guide block do not accurately correspond to each other in the vertical direction, the disk may interfere with the support groove and the guide groove when the disk is taken in and out. In such a case, not only will the disc not be accurately engaged with the support groove, or it will be difficult to take out the stored disc, but also a large load will be applied to the disc.

For this reason, conventionally, high precision is required for manufacturing and assembling the disk support block and the guide block, which requires time and labor for manufacturing and assembling the disk, and the manufacturing cost of the disk storage case increases. was there.

Further, the guide block is integrally formed of a synthetic resin material. Therefore, in order to form a plurality of slit-shaped guide grooves in the guide block at predetermined intervals in the vertical direction, as a mold for forming the guide block, a complicated thin plate having a plurality of thin plates at predetermined intervals is formed. It is necessary to have a simple configuration. However, it is very difficult and time-consuming to manufacture these plural thin plates with high accuracy at predetermined intervals.

Moreover, in order to mold the guide block with high accuracy using such a mold, the mold is forcibly cooled by circulating cooling water in a cooling passage in the mold. It is necessary to suppress heat generation of the mold during molding. However, since it is impossible to form a cooling passage in a plurality of thin plates provided in the mold, these thin plates cannot be cooled sufficiently. Therefore, when molding a plurality of guide blocks with a mold, after the guide block has been molded, it is necessary to wait until the thin plate has cooled sufficiently before starting the molding of the next guide block. In other words, a large waiting time occurs until the next guide block is formed, so multiple guide blocks cannot be formed continuously and efficiently, resulting in reduced productivity and higher production costs. There is a problem of inviting.

The present invention has been made by paying attention to the problems existing in such conventional techniques. The first purpose is to provide a disk storage case which has a simple structure and can be easily manufactured, which is excellent in productivity, can reduce the manufacturing cost, and can be easily assembled. It is in.
