Description

Description: BACKGROUND OF THE INVENTION [0001] The present invention relates to a plurality of discs.
Using a magazine loaded with multiple
For disc players who select and play any disc
Related. 2. Description of the Related Art As a conventional disk player of this kind,
The plate on which the disc is mounted
Slide the plate out of the magazine
With this, it is located on the pickup of the player body.
And a disc provided in the player body
Chuck the disc on the plate with the chucking mechanism.
There is known a pump that rotates the pump. However, in such a conventional configuration, the
Space for pulling out discs from the magazine
It is necessary to secure it on the layer side, and that space is
There is a disadvantage that the shape of the layer is enlarged. Therefore, the selected disk is mounted.
Select the disc instead of sliding the plate
With disks located at the top and bottom.
The pickup and the pickup
A pickup arm equipped with a scouting mechanism
Move the disc into the magazine by rotating
A pumping structure is conceivable. According to this, the selection disc
This drawer is more
Minimize the size of the disc player because space is not required
be able to. SUMMARY OF THE INVENTION
The arm is longer than the radius of the disc.
During playback, the disc and disc chucking mechanism
Place a heavy object such as a pickup. This pickup
The arm is supported only by the axis of rotation, so during playback
Vibration is likely to occur due to eccentricity of the disk. Also, resonance
If this occurs and the vibration increases, the optical lens
Sometimes jumps to a track that you do not want (sound skipping). SUMMARY OF THE INVENTION A disk player according to the present invention
In consideration of the above points, multiple discs are
Using magazines loaded one by one on the
Disc to select and play any disc
In the player, the disc catching mechanism and the pick
Pickup mounted with a rotatable pivot
Arm and the pickup arm from the storage position to the reproduction position.
Rotating means for rotating the disk in parallel with the disk surface;
The pickup in the playback position of the pickup arm
A concave portion for fitting with the arm;
Contact means for regulating vertical movement of the backup arm
Is provided. FIG. 1 is a block diagram showing an embodiment of the present invention.
It will be described based on. (Schematic explanation) First, the outline is explained based on the perspective view of FIG.

FIG. 3 is a plan view showing a state in which the magazine 1 is loaded in FIG. Ma
FIG. 7 shows the removal of the magazine 1 and the player main body 5.
Mainly on the player chassis 3 and on both sides thereof.
FIG. 3 is a plan view showing an elevator mechanism 4 placed.
Two grooves are provided on the back surface of the bottom plate 15 of the magazine 1 in the front-rear direction.
15d and 15e are formed. Magazine 1 plays
When the groove 15d, 15e is accommodated in the
Guide projections 3c, 3 formed on the
c, 3c 'engage. Back side of player chassis 3
Is provided with a lock plate 6 for locking the magazine 1.
I have. The first projection 6a projecting into the accommodation space is
Guide holes long in the front-rear direction formed in the layer chassis 3
3e, and also projected into the accommodation space
Is located between the guide projections 3c, 3c (immediately).
(A position corresponding to the groove 15d).
It is guided to the L-shaped guide hole 3d that turns rightward on the rear end side.
It has become. And the lock plate 6 is attached to the spring 6c.
Is biased forward. Magazine 1 is mounted in the accommodation space
When the first protrusion 6a is inserted,
6c, the lock plate 6 is pushed as shown in FIG.
Move backward. Then, the second protrusion 6b is inserted into the guide hole 3
Enter the right turn of d. This right turn is a magazine
One groove 15d corresponds to the locking groove 15d '(see FIG. 6).
The second protrusion 6b enters the locking groove 15d '.
And the magazine 1 is locked. What
The locked state of the magazine 1 is
Is detected by the switch 100 pressed
I have. The magazine 16 has the above-mentioned loose
Restricting pieces 151a, 15 in restricting members 15a, 15b
Arc holes 16a, 16a corresponding to the rotation range of 1b are formed.
Has been established. The separation restricting members 15a and 15b are
The engaging pieces (not shown) projecting toward the grooves 15d and 15e are
Have. Therefore, the magazine 1 is located in the player accommodation space.
When the guide protrusions 3c 'are mounted on the
The projections 3c press the engaging pieces, respectively.
The eccentric regulating members 15a and 15b rotate and are shown in FIG.
As described above, the regulating pieces 151a and 151b
Position within the arc holes 16a, 16a so as not to stop
Then, the vertical movement of the upper lid 16 is allowed. FIG. 6 shows a side view of the player main body 5.
Are projected from the four guide projections 5a.
The vertical guide groove 3b of the chassis 3 and the elevator
The state in which it is engaged with the step-like groove 41c of the ride plate 41
Is shown. The player main body 5 is provided with the elevating slide.
When the plate 41 slides back and forth, it is in the step-like groove 41c.
Thus, the height position for supporting the guide projection 5a changes,
With this change, the guide projection 5a moves the vertical guide groove 3b.
Move, thereby moving the player body 5 up and down
become. FIG. 8A is a right side view of the player section 2.
FIG. 3B is a left side view. This side part
The elevator slide plate 41 in the elevator mechanism 4 is
Is placed. Here, the right elevating slide plate 41
Denotes a reference numeral 411, and the left and right elevating slide plate 41 is attached.
Is denoted by reference numeral 412. Elevating slide plate 4
1 (411, 412) have guide holes 41a in the front-rear direction.
Are formed and project from the side surface of the player chassis 3.
The elevating slide plate 41 is moved forward and backward by the protrusion 3a
It is guided in the direction and moves. Lifting switch
A rack 41b is formed on the upper edge of the ride plate 411.
A predetermined gear in the gear group 42 is attached to the rack 41b.
YA is meshed. The driving force of the driving motor 43 is

The slide plate 411 moves back and forth. Elevating slide plate
The back and forth movement of 411 is performed by the synchronous connection lever shown in FIG.
44 to the other slide plate 412 for lifting.
You. The synchronous connection lever 44 is turned horizontally around a shaft 44a.
The lifting slide plate 411 is configured to move.
If you move forward, the elevating slide plate 412 moves backward.
It is going to advance. The traveling directions of both are opposite to each other
Therefore, the stepped groove 41c is also moved up and down by the slide plate 411.
And 412, the up and down directions are opposite. What
FIG. 8 shows how the vertical position of the guide projection 5a changes.
It is virtually shown corresponding to each step of the step-like groove 41c.
You. The lifting and lowering slide plate 411 moves
The layer body 5 moves up and down.
Height corresponding to the disc) is attached to the elevating slide plate 411.
Slits 4 formed at predetermined intervals in the front-rear direction
.. Are detected by the photo sensor 102 (see FIG. 7).
You can know that. In addition, the elevating slide plate 41
1 moves forward to the foremost side, the elevating slide plate 41
The lock plate 6 is pushed by an operation piece (not shown)
1 is ejected. Note that, as described above,
The position of the elevating slide plate 411 is determined by the sensor 102.
However, for this purpose, a reference point must be set.
Need to be The switch 101 in FIG. 7 is provided for this purpose.
The slide plate 411 has the third and fourth discs.
When it is at the position corresponding to between the discs,
Set to work. Therefore, this behavior
Thereafter, the slide plate 411 further moves, and the photo sensor 10
If the output of No. 2 is detected, it is located at the position corresponding to the fourth sheet.
It turns out that there is. Depending on the direction of slide plate movement
It may be the third piece, but this is a slide
If you decide the direction to move the board, it can be any position
I understand. FIG. 9 is a plan view of the player main body 5.
The plate is separated inside the housing side plate 52 of the player body 5.
A slide plate 51 is provided so as to be slidable in the front-rear direction.
I have. Note that the reference numeral 521 is assigned to the right housing side plate,
522 is attached to the case side plate of the right side plate.
