The operation of the multi-disc player configured as described above will be described below with reference to FIGS.

In order to play the disk 26, it is necessary to place the disk 26 on the disk mounting portion 3a of the tray 3. Therefore, first, when the operation knob 9 is pressed so that the tray 3 is put out from the opening 2a of the front panel 2 to the outside. Then, the motor 31 of the loading drive unit 7 rotates in response to a command from the electric circuit unit 8, and rotates the loading drive gear 36 in the reverse direction via a reduction mechanism including the motor pulley 32, the belt 33, and the pulley gear 34.

Then, the loading drive gear 36 is driven to move in the direction A by the rack portion 38a of the rack plate 38 meshing with the tooth portion 36b of the loading drive gear 36, and the loading cabinet 1 moves in the direction A.

At this time, the leading end portion 36c of the loading drive gear 36 is guided along the guide portion 38b of the rack plate 38, and the tooth portion 36b and the rack portion 38a of the rack plate 38 do not cause a tooth jump or the like even when moved in the direction A. And the pitch is constant. Further, the two rollers 41 rotatably attached to the loading cabinet 1 move in the direction A while rotating on the protrusions 5a of the chassis 5 while supporting the weight of the loading cabinet 1 and the like.

When the loading cabinet 1 moves in the direction A, the rack 1c of the loading cabinet 1 meshes with the timing gear (A) 43 and the rack 1d meshes with the timing gear (B) 44. ) 43, the timing gear (B) 44 and the timing gear shaft 42 rotate, but since the timing gear (A) 43, the timing gear (B) 44 and the timing gear shaft 42 are fixed, they rotate at the same time. Cabinet 1
The movement amount of the rack part 1c and the rack part 1d becomes the same, the loading cabinet 1 is parallel to the timing gear shaft 42,
That is, it moves in the direction a in parallel with the front panel 2.

As shown in FIG. 5, the roller 43a of the timing gear (A) 43 is provided with a rib 1e of the loading cabinet 1.
The roller 44a of the timing gear (B) 44 is rotating while supporting the weight of the loading cabinet 1 and the like by the rib 1f of the loading cabinet 1, and the guide 44b of the timing gear (B) 44 is rotating. The width of the ribs 1f is supported to restrict the movement of the loading cabinet 1 in the left-right direction. When the loading cabinet 1 is stored in the opening 2a of the front panel 2, the opening 2a of the front panel 2 is loaded. The left and right clearances of the front portion 1e of the cabinet 1 do not become unbalanced.

When the loading cabinet 1 moves in the direction A and reaches the position shown in FIG. 1B, the switch 39 is turned off by the cam portion 38c of the rack plate 38 to which the switch 39 is connected, and the rotation of the motor 31 stops. The movement of the loading cabinet 1 in the direction A is stopped.

Then, place the disk 26 on the disk mounting portion of the tray 3.
Place on 3a.

Then, the optical sensor 51 detects that the disk 26 has been mounted, and rotates the tray 3 in the right direction so as to mount the second disk 26 on the disk mounting portion 3a of the tray 3. When a command is issued from the electric circuit section 8, the motor 11 of the tray drive mechanism 6 rotates in two directions,
The intermediate gear 16 is rotated via a reduction mechanism including the belt 12, the belt 13, and the pulley gear 15.

Then, as shown in FIG. 3, the intermediate gear 16 tries to rotate the planetary gear 18 attached to the rotatable planetary arm 19, but the planetary gear 18 is biased by the compression spring 21 by the spring pressure. Since the planetary gear 19 is harder to rotate than the rotatable planetary arm 19, the planetary gear 19
The tray drive gear 28 rotates to drive the teeth 3c of the tray 3 meshed with the teeth 28b, and the tray 3 rotates in the right direction.

When the disc mounting portion 3a of the tray 3 comes to a position where the previous disc mounting portion 3a matches, the tray 3
The rotation of the motor 11 stops and the rotation of the tray 3 in the right direction stops because the rib 3d provided on the lower surface of the tray 3 blocks the light of the optical sensor 47. Then, the disk 26 is mounted on the disk mounting portion 3a of the tray 3. Further, the third, fourth, and fifth disks 26 can be similarly placed on the tray 3.

Also, the disk mounting part where the disk 26 is not mounted
3a can be passed to the next disk mounting portion 3a by pressing the operation knob 9 to give a command.

Next, when the operation knob 9 is pressed to play the disk 26, the motor 11 of the tray drive mechanism 6 rotates in two directions, and the tray 3 is rotated in the same direction as the above operation.
When the disk mounting portion 3a of the tray 3 on which the disk 26 is mounted comes below the clamper 45, which is the playing position, the rib 3d on the lower surface of the tray 3 blocks the light of the optical sensor 47. The rotation of 11 stops, and the rotation of the tray 3 in the right direction stops.

Then, since the motor 11 rotates in the direction C opposite to the above, the planetary arm 19 rotates in the direction E until the planetary gear 18 meshes with the teeth 22a of the elevating cam 22 by the operation reverse to the above, and The cam 22 is rotated. Then, the inclined cam portion 22b of the elevating cam 22 rotates, and the pin 2 of the associated disc playing portion 25 is rotated.
Since the position of 5c is changed, the disc playing section 25 is rotated in the direction H by the spring force of the pulling spring 48 about the horizontal axis 24. The turntable 25a of the disc playing section 25 carries the disc 26 together with the clamper 45 through the hole 3b of the disc mounting section 3a of the tray 3. At this time, the switch 27 is turned on by the cam portion 22c of the associated elevating cam 22, so that the rotation of the motor 11 stops and the rotation of the disc playing portion 25 in the h direction also stops.

Then, the disk playing section 25 operates to start playing the disk 26.

Next, when playing another disc 26, pressing the operation knob 9 causes the motor 11 to further rotate in the direction C in response to a command from the electric circuit section 8 to rotate the elevating cam 22 in the same manner as described above. The inclined cam portion 22b pushes the pin 25c of the associated disk playing portion 25, so that the disk playing portion 25 rotates around the horizontal axis 24 in the direction G. Then, the holding of the disk 26 between the turntable 25a and the clamper 45 of the disk playing unit 25 is released, and the disk 26 is mounted on the disk mounting unit 3a of the tray 3. At this time, the switch 27 is turned off by the cam portion 22c of the associated elevating cam 22, so that the rotation of the motor 11 is stopped and the rotation of the disc playing portion 25 in the direction G is also stopped.

Then, since the motor 11 rotates in the two directions, the planetary arm 19 rotates in the direction F to rotate the tray driving gear 28 as described above, and the disc mounting portion 3a of the tray 3 is moved to the playing position. Rotate the tray 3 in the direction until it comes. Then, the motor 11 rotates in the direction C again, and the disk playing section 25 rotates in the direction H as described above to carry the disk and start playing the disk 26. Similarly, 3rd, 4th, 5
Since the second disc 26 can be played, the next disc 26 is automatically moved when the performance of each disc 26 is completed without pressing the operation knob 9 each time, so that continuous playing can be performed. .

In addition, since the tray 3 is outside the opening 2a of the front panel 2 even while the disc 26 is playing, the disc mounting section 3a (see FIG. Disk 26 in another state)
The disk 26 can be replaced with a new one or if the disk 26 is not placed there, the disk 26 can be refilled.

Further, when it is desired to store the loading cabinet 1 in the opening 2a of the front panel 2 while the disk 26 is being played, when the operation knob 9 is pressed, the loading drive unit 7 is operated by a command of the electric circuit unit 8. Since the motor 31 rotates in the opposite direction to rotate the loading drive gear 36 in the null direction, the loading drive gear 36 is driven by the rack portion 38a of the rack plate 38 to move in the direction B, and the loading cabinet 1 is rotated in the direction B. Move in the direction. When the loading cabinet 1 is located in the position where the loading cabinet 1 is stored in the opening 2a of the front panel 2, the cam 39c of the rack plate 38 with which the switch 39 is engaged is turned off, and the rotation of the motor 31 stops and the loading is stopped. The movement of the cabinet 1 in the direction B is stopped.

The operation of loading the disk 26 on the tray 3 and moving the loading cabinet 1 in the direction B with the disk 26 in the playing state has been described above. It is also possible to move the cabinet 1 in the direction B and store it in the opening 2a of the front panel 2 before playing the disk 26.
The loading cabinet 1 can be moved in the direction A while the playing cabinet is in the playing state, and the loading cabinet 1 can be taken out of the opening 2a of the front panel 2.

That is, the loading cabinet 1 can be moved in the a or b direction without interrupting the performance of the disc 26, and the disc 26 can be replaced or refilled arbitrarily.
