A pair of left and right projecting plates 42, 43 are mounted on the chassis 10 to relatively push up the pair of left and right roller supporting plates 26 and the stopper mounting plate 35 from above.

Next, the operation of the conventional disc player having the above structure will be described with reference to FIGS .

First, when the disks 7 are taken out from the disk magazine 4 one by one and loaded on the disk table 14, first, the movable chassis 16 is moved to the disk magazine 4 by driving the three transfer screws 17. The disc 7 is transferred along the doorway 8 in parallel with the arrow e or f direction which is a direction perpendicular to the arrow c direction which is the take-out direction of the disk 7. When the movable chassis 16 reaches the height corresponding to the designated disc storage shelf 6 of the disc magazine 4 and is detected by the encoder (not shown), the transfer screw 17 is stopped.

Next, the slider 19 of the disk ejecting mechanism 23 drives the predetermined slide plate 24 in the disk magazine 4 in the direction of arrow c, and the predetermined disk 7 in the disk magazine 4 is shown by the dotted line in FIG. From the storage position in the disc magazine 4 shown to the outside 1 of the disc entrance / exit 8
It is selectively extruded in the direction of arrow c to the position shown by the dotted line.

At this time, the drive roller 20 of the disc take-out mechanism 23 has already been rotated in the direction of arrow g in FIG.
The tip of the disk 7 pushed to the position indicated by the one-dot chain line in FIG. 7 has the pressure spring 2 between the drive roller 20 and the pressure roller 21.
It is inserted against 9.

Then, as shown in FIG. 9 , the driving roller 2
The disk 7 is continuously pulled in the direction of arrow c by the driving force of 0, and the disk 7 is taken out horizontally from the disk inlet / outlet 8 in the direction of arrow e. At this time, the disc 7 is pressed from below by the guide roller 22 by the lever action by the pressure force of the pressure roller 21 in the direction of the arrow i, and the guide roller 22 guides the disc 7 horizontally so that the disc 7 becomes a pair of left and right. It is taken out between the hold members 40 and 41 in the direction of arrow c.

Then, as shown by the solid line in FIG. 7 , the outer circumference of the disk 7 completely taken out in the direction of the arrow c to the outside of the disk magazine 4 has a pair of left and right stopper members 37, 38.

Almost at the same time, the stopper mounting plate 35 is relatively pushed up from below by the pair of left and right projecting plates 43 in the upward arrow f direction, and the stopper mounting plate 35 resists the spring 36. Is rotated in the direction of the arrow m, and the pair of left and right stopper members 37 and 38 are moved to the disk 7
Is escaped to the outside and above.

Immediately after the clamp arm 33 is rotated in the direction of arrow m against the spring 34 by the stopper mounting plate 35 and the above-mentioned hold of the disk 7 is released,
The disc clamper 31 is lowered in the direction of the arrow e within the clamper mounting hole of the movable chassis 16 in the direction of arrow e, and the magnetic attraction force of the magnet (not shown) embedded in the lower surface of the disc clamper 31 causes the disc clamper 31 to move. Causes the center hole 7a of the disc 7 to be forcibly fitted to the center hub 14a of the disc table 14 in the direction of the arrow e, so that the disc 7 is magnetically chucked on the disc table 14, and the disc 7 is attached to the optical pickup device 15 Is approached from the direction of arrow e.

By moving the movable chassis 16 in the direction of arrow e, the drive roller 20 moves from the disk 7 to the direction of arrow e.
When the movable chassis 16 is separated in the direction, the sensor (not shown) detects that the movable chassis 16 has been transferred to a predetermined position in the arrow e direction, and the transfer screw 17 is stopped.

After mounting the disc, the disc table 1 is rotated by the spindle motor 13.
The disk 7 is rotationally driven by 4, and the disk 7 is scanned in the direction of the arrow n by the optical pickup device 15 to perform a desired reproducing operation of the disk 7.

The disc unloading operation for returning the reproduced disc 7 to the original disc storage rack 6 in the disc magazine 4 is the reverse operation of the disc loading operation described above.

That is, when the movable chassis 16 is moved from the mounting position shown in FIG. 10 in the direction of arrow f, as shown in FIG. 9 , the stopper mounting plate 35 and the clamp arm 33 are provided.

The pressure contact roller 21 presses the disk 7 onto the drive roller 20 to hold the disk 7, and the drive roller 20 lifts the disk 7 from the disk table 14 in the direction of arrow f. When the encoder detects that the movable chassis 16 has reached the height corresponding to the original disc storage shelf 6, the drive roller 20 is rotationally driven in the direction of arrow h in FIG. Four
The disc is inserted into the original disc storage rack 6 from the disc entrance 8 in the direction of arrow d. When a sensor (not shown) detects that the disc 7 has been completely sent out between the drive roller 20 and the pressure roller 21 in the direction of arrow d, the disc set arm 44 in the disc magazine 4 serves as a fulcrum. The disk 7 is driven to rotate in the direction of arrow q around the pin 45, and the disk 7 is moved by the disk set arm 45.
There is correctly set is pushed in the direction of arrow d to the retracted position shown in dotted lines in FIG. 7 of the disc magazine 4.

By the way, this type of disc player
As shown in FIG. 11 , the magazine insertion slot 3 of the player main body 1 is horizontally installed in a horizontal orientation, and as shown in FIG. 12 , the magazine insertion slot 3 of the player main body 1 is oriented upward. It is configured so that it can be used properly when it is installed vertically and vertically. And
When installed vertically, the disk 7 in the disk magazine 4 becomes vertical, and the disk 7 taken out from the disk magazine 4 in the direction of arrow c is placed in the vertical position on the disk table 14 in the direction of arrow e. It will be installed from the direction.

At this time, as shown in FIG.
When the disk is mounted on the disk table 14 in the vertical direction from the lateral direction which is the arrow e direction, the outer periphery of the disk 7 is released at the moment when the pressing roller 21 is separated from the drive roller 20 in the arrow j direction and the hold of the disk 7 is released. Is held by the stopper members 37 and 38 and the holding members 40 and 41. Then, after that, the disk clamper 31 presses the disk 7 in the direction of arrow e, and the center hole 7a of the disk 7 is fitted into the center hub 14a of the disk table 14 from the direction of arrow e to perform magnetic chucking.
