Claims

[Claims for Utility Model Registration] (1) In a disc guide mechanism of a disc playback device, either one of a first disc and a second disc whose diameter is larger than that of the first disc is selectively selected. , a disk holding means that is received inside the disk playback device and is pivotally supported by the disk playback device so as to be movable to open and close with respect to the turntable of the disk playback device; a first disk supporting means that is pivotally supported by a holding means and supports a first disk received in the disk holding means at a predetermined position; and a first disk supporting means that supports a second disk received in the disk holding means at a predetermined position. and a second disk support means for supporting the first disk, wherein when the second disk is received in the disk holding means, an end of the second disk is attached to the first disk. A disk guide mechanism that rotates to avoid the second disk by coming into contact with the disk support means. (2) A disk guide mechanism of a disk playback device selectively receives either a first disk or a second disk whose diameter is larger than that of the first disk. , a disc holding means pivotally supported on the disc playback device so as to be movable in opening and closing with respect to the turntable of the disc playback device; a first disk support means that supports a first disk received in the disk holding means in a predetermined position; and a second disk support that supports a second disk received in the disk holding means in a predetermined position. means, wherein the first disk support means rotates the first disk support means to hold the second disk when the disk holding means is opened with respect to the turntable of the disk playback device. A disk guide mechanism having a support means and a different disk support position. (3) In a disc guide mechanism of a disc playback device, either one of a first disc and a second disc whose diameter is larger than that of the first disc is selectively received within the disc guide mechanism. , a disc holding means pivotally supported on the disc playback device so as to be movable in opening and closing with respect to the turntable of the disc playback device; a first disk support means that supports a first disk received in the disk holding means in a predetermined position; and a second disk support that supports a second disk received in the disk holding means in a predetermined position. means, wherein the first disk support means has a member for sliding an end of the second disk, and when the second disk is received in the disk holding means, the first disk support means has a member for sliding an end of the second disk. When the end of the disk slides and comes into contact with the member, the second disk
