4, the slide body 111 slides clockwise in the disc circumferential direction, and the protruding portion 116 of the slide body 111 pushes the lever portion 26 of the inner body 12 of the magazine 1 to move the inner body.
12 and the CD in the lowered position, the holder 30, and the inner body 12 are integrally rotated while moving up in the clockwise direction. Therefore, the gap opened in the magazine 1 is closed.

When the slide body 111 reaches the initial position, the reverse rotation of the motor 136 is stopped and the initial standby state is restored. In this standby state, the magazine 1 is pulled out from the changer device 2 and removed.

When changing the CD for reproduction, the arm 61 is returned from the reproduction state to the standby position and the magazine 1 is once returned to the standby state, and then the lifting motor 81 is driven to rotate in the forward and reverse directions. A holder in which the recording / reproducing unit 56 and the selection member 98 are loaded with the next selected CD.
In accordance with the height position of 30, the reproduction can be performed from the standby state to the reproduction state as described above.

As described above, a plurality of CDs are stacked and arranged.
Move any of the CDs in the disc stacking direction,
By opening a gap so as to face the CD to be played back, and by inserting the recording / playback unit 56 into the gap, the CD is rotated by the recording / playback unit 56 at the position where a plurality of CDs are arranged to be played back. The changer device can be downsized.

Therefore, when the changer device 2 is used as, for example, a six-compartment CD changer for an automobile, the changer device 2 can be incorporated in the central portion of the instrument panel.

Moreover, since the arm 61 and the selection member 98 can be integrally moved in the disc stacking direction of the magazine 1 by the drive of the motor 81 through the interlocking means including the cylindrical body 142 and the slide plate 94, the drive is performed. Motor as a means
Only one of 81 is required, and the structure can be simplified, and the positions of the holder 30 and the arm 61 selected by the selection member 98 in the disc stacking direction can be surely associated with each other.

It should be noted that the recording / reproducing disc has a reproduction-only,
Both recording and playback are included. Therefore, the recording / reproducing disc is not limited to a CD, but includes a video disc, a magneto-optical disc capable of recording / reproducing, a magnetic disc, and the like, and can be applied to a recording / reproducing apparatus for performing recording / reproducing of these recording / reproducing discs.

In the recording / reproducing apparatus for recording / reproducing on / from the magnetic disk, the recording / reproducing unit 56 uses a recording / reproducing head for magnetic recording / reproducing on / from the magnetic disk.
