As shown in these figures, the disc changer includes a disc storage body 2 in which a plurality of discs 1 are stored in parallel to each other, and a thickness direction of the plurality of discs 1 stored in the disc storage body 2. It is equipped with a carrier 3 that moves to the position where the desired disk 1 is taken from the disk housing 2 and returns to the original position after the disk 1 is reproduced. A guide for loosely fitting a part of the disk 1 in the vicinity of the outer peripheral edge of the disk 1 into the carrier 3 when the disk 1 is taken in from the disk housing 2 and when the disk 1 is returned. A disk guide 5 having a groove 5a is provided. The disc guide 5 is rotatably attached to the carrier 3 about a rotation shaft 3d, and has a traction spring 7
Is urged by. Due to this urging, the disk guide 5 is stopped by the stopper portion 3b embedded in the carrier 3.
Are abutted against each other and are parallel to each other. When the disc 1 is reproduced, the disc guide 5 is slightly rotated against the spring 7 so that the disc 1 can freely rotate.

Reference numeral 3a denotes a holding portion fixed to the carrier 3 for holding an end of the spring 7, and 3e denotes guide pins implanted in the carrier 3, and the guide pins 3e are positioned. The member 6 is attached so as to be movable in the direction toward the disc housing 2. Reference numeral 2a is a guide concave portion. By fitting the positioning member 6 into the concave portion 2a, the carrier 3 is positioned with respect to the disc housing 2 so that the desired disc 1 can be taken out (or returned). . Reference numeral 4 is a disk guide portion of the disk housing 2, 10 is a plate spring, and 11 is a holding plate.

In the disk changer constructed as described above, since the positioning member 6 and the disk guide 5 are arranged on the center line of the thickness of the disk 1 taken into the carrier 3, the carrier 3 is described. It is necessary to make the shape of the disk guide 5 small in order to make the outer shape of the disk compact. Therefore, in order to provide the disc guide 5 with a predetermined strength, it is necessary to use an expensive material. Further, in order to accurately arrange the positioning member 6 and the disc guide 5 on the center line of the thickness of the disc 1 taken into the carrier 3, the positioning member 6 and the guide concave portion 2 of the disc storage body 2 are arranged. It was necessary to constantly manage the positional relationship, the positional relationship between the positioning member 6 and the carrier 3, and the positional relationship between the guide groove 5a of the disk guide 5 and the carrier 3.
