Next, the position of the target disk is detected by the detected member 83 and photocoupler 84a to 84c shown in FIGS. 10 and 11, and the position of the movable chassis 16 is finely adjusted to correspond to this, and a A push-out member 41 is provided on the disc 10 to be played.
reaches the engagement position with the tray 11 or 12 carrying the.

In this way, when the pushing member 41 reaches the engagement position with the tray carrying the disc 10 to be played, the motor 48
is rotated, and the pushing member 41 is rotated via the moving member 43. Therefore, as shown in FIG. 5 and FIG. 7, the tray carrying the disc 10 to be played (for example, tray B12) protrudes from the case 9 of the magazine 5, and as shown in FIG. The disk 10 moves to a position concentric with the disk supporting surface 52a of the turntable 52, that is, to a position directly beside the disk supporting surface.

Following the disk ejection operation caused by the movement of the moving member 43, the clamper cam member 58 and rotational movement member 66 are rotated by further movement of the moving member. Note that after the tray 12 is pushed out of the magazine 5, the engagement state between the pushing member 41 and the moving member 43 is released by a release mechanism (not shown).

As the rotational movement member 66 rotates, the action of the cam portion of the rotational movement member causes the rotation in FIG.

As shown in FIG.
Attach it to the disk holding surface of No.2. At the same time, the pressing member 55 is clamped by the action of the cam portion of the clamper cam member 58. After this, each gripping member 67, 68, 69 is removed from the disc 10.

In this way, it becomes possible to play, and the turntable 52 and optical pickup (not shown) operate to start playing.

When the performance is finished, the disc 10 is stored in the magazine 5, but this disc storage operation is simply performed by following the reverse process of the disc loading operation described above, and will not be described in detail.

Thereafter, the above operation is repeated according to the specified number of songs.

The magazine 5 is ejected from the player by pressing the eject button included in the operating section 3 shown in FIG. 1, which activates the solenoid plunger 30. At this time, the manual knob 29 shown in Figure 1 etc.
By operating the solenoid plunger 30, the solenoid plunger 30 is moved to correspond to the magazine to be ejected.

Effects of the Invention As detailed above, the magazine disc player according to the present invention includes a mounting part capable of holding a plurality of magazines, each of which can accommodate a plurality of discs in an array, and a playing means guided in the direction in which the magazines are lined up. and a plurality of disk moving means for moving the disk between the magazine and the playing means, the plurality of disk moving means being provided corresponding to each loading position of the magazine and locking the magazine at the insertion position. a single ejecting means that is movable in the direction in which the magazines are lined up and releases the magazine from being locked by the locking means, and the ejecting means is manually positioned from outside the player housing. ejection means and manual positioning means.

By arranging a plurality of magazines in parallel and moving the playing means in the direction in which they are lined up, selective automatic playing of many discs is achieved, and
When replacing a disk, it is only necessary to attach and detach the magazine containing the disk to be replaced, resulting in good operability.

Further, since it has the above-described locking means, ejecting means, and ejecting means manual positioning means, any magazine can be selectively attached to and detached from the player body.
When a disk is to be replaced, only the magazine containing the disk to be replaced can be attached or removed, which allows the disk to be replaced quickly and improves operability.

Further, since the ejecting means is single, the number of parts is reduced, and the manual ejecting means positioning means is simple in structure, so a cost reduction is achieved, and
This makes it easier to downsize the player as a whole.
