It is locked by the arm portion 29a and rotates counterclockwise, pushing up one end of the holding lever 43 (see FIGS. 2 and 5B).

Next, the operation of the disk loading device 1 having the above structure will be explained.

In the initial state, the disc tray 2 is pulled into the playback device 1 as shown in FIG.
The decorative board 7 is flush with the front panel 3 of the reproduction device and closes the opening 3a. The knob 15 is also drawn into the opening 7a of the decorative plate 7, and the decorative plate 7
It is flush with the front of the.

When loading a disk, switch SW ₁
Press. As a result, the motor 21 is rotated in the reverse direction, and the disk loading device 1 operates in the same manner as in the disk detachment operation, which will be described later. In other words, the moving base 5 is the arrow X ₂
As shown in FIG. 1, the disk tray 2 protrudes from the opening 3a in the direction of arrow _X2 .
Moreover, it is in a state of rising in _{the two} directions of arrow Z. Further, as shown in FIG. 4A, the first rack 8A is pushing the switch SW ₂ , and the switch SW ₂ is turned on (see FIG. 6D). The second rack 9A is moving in the direction of arrow _X2 with respect to the first rack 8A, and in relation to this, the disk tray 2 is
The knob 15 is raised in the _Z2 direction, and the knob 15 is in the opening 7a.
more prominent. Further, the clamp arm holding member 29 is moving in the direction of _arrow The clamper 26 is rotated in the _two directions of arrow A, and the clamper 26 is in the raised, non-clamped position. Further, both switches SW ₃ and SW ₄ are in the OFF state (see FIGS. 6E and F). Further, the lock pawl 24 is rotated counterclockwise by a spring 52, and the gear 23 is locked by the lock pawl 24 (see FIG. 4C).

Next, place the compact disc 4 to be loaded on the disc tray 2 as shown by the two-dot chain line in FIG. 1, and operate the switch SW ₁ (6th
(See t ₀ in Figure A). By operating this switch, the plunger 40 is excited (see _t0 in Fig. 6B), and switches SW ₁ and SW ₂ are ANDed, and the loading motor 21 is started and rotates forward (Fig. 6C). of
(see _t1 ).

When the plunger 40 is energized, the lock pawl 24 rotates clockwise against the spring 52, as shown in FIGS. 4A and 5A, and the lock on the gear 23 is released. Further, when the lock claw 24 rotates, the holding lever 43 is released from the lock and the spring 46 is released.
As a result, it rotates counterclockwise to a position where it is locked to the stopper pin 48, and one end thereof is in a state where it can oppose and receive the bent arm portion 24a of the lock pawl 24.

When the motor 21 rotates normally, the gears 19A and 19B rotate in the direction of arrow _B1 via the gear train 22, and the moving base 5 is moved in the direction of arrow _X1 by driving the racks 8A, 9A and 8B and 9B. The compact disc 4, placed on the disc tray 2, is then drawn into the playback device through the opening 3a.

When the retracting operation of the disk 4 starts, the rack 8A moves away from the switch SW 2 and the rack 8A moves away from the switch SW _{2 .}
is turned off (see t ₁ in FIG. 6D), and the plunger 40 is accordingly brought into a de-energized state (see t ₀ to t ₁ in FIG. 6B). That is, since the plunger 40 is kept in an excited state until the retracting operation of the disk 4 starts, the lock pawl 24 is reliably released. After the plunger 40 is de-energized, the lock pawl 24 is retained by the holding lever 43 and held in the unlocked state, as shown in FIG. 5A.

As shown in FIGS. 2 and 4B, the movable base 5 has guide rails 11A, 1 on the left and right sides of the decorative board 7.
It collides with the end face of 1B and moves to the final position where movement in the direction of arrow _X1 is restricted. In this state, the first racks 8A and 8B are just disengaged by the gears 19A and 19B, and the switch _SW3 is pushed by the first rack 8A and turned on (Fig. 6E).
(see t ₂ ). That is, the switch SW ₃ detects that the retracting operation of the movable base 5 in the direction of the arrow _X1 has been completed to the end. Incidentally, while the disc tray 2 is kept in the raised position, the entire disc is pulled into the playback apparatus, and the compact disc 4 is completely accommodated within the playback apparatus.

First, in this state, the first racks 8A, 8B
and the second racks 9A and 9B are shown in Fig. 6G and H.
They move integrally in the direction of arrow _X1 as shown from _t0 to _t2 . After this, the second racks 9A, 9B are connected to the springs 14 independently of the first racks 8A, 8B.
A _, 14B are _pulled and forcibly moved in the direction _{of arrow} After that, the voltage applied to the motor 21 is increased.

Thereafter, the applied voltage is increased and the motor 21 rotates forward with high torque, and the second racks 9A and 9B move in the direction of arrow _X1 against the springs 14A and 14B, respectively.
Move to the position shown in Figure C (t ₂ to _{t 3} in Figure 6 H)
reference). The movement of the second rats 9A, 9B at this time causes the pins 17a, 17b (the remaining two are not shown) to move into the oblique elongated holes 9A-c, 9A-d, 9B-
c, 9B-d are guided diagonally downward and displaced downward, and the disk tray 2 is pulled down,
It is guided by guide pins 18a to 18d and descends in the direction of arrow _Z1 , that is, vertically (see _t2 to _t3 in FIG. 6I). During the lowering of the disk tray 2, the compact disk 4 is inserted into the center hole 4a as shown in FIG. 4C.
is fitted into the center hub of the turntable 31 and received by the turntable 31, floating relatively above the disk tray 2 and supported on the turntable 31.

Here, the rectangular disk tray 2 is pulled down uniformly at the locations near each corner (4 locations in total), and the locations near each corner are pulled down by the guide pins 18a.
18d, the lowering operation of the disk tray 2 is performed reliably and smoothly.

When the movable base 5 is retracted, the rear parts of the second racks 9A and 9B enter below the rollers 51A and 51B, and the rollers 51A and 51B move as shown in FIG.
As shown in , in addition to the locking pieces 29e and 29f, the flat surfaces 9A-c and 9B- of the second racks 9A and 9B
It is in a locked state by e. Further, in the process of the second racks 9A, 9B moving as described above, the clamp arm holding member 29 is pushed and moves in the direction of arrow _X1 against the spring 30, and the locking pieces 29e, 29
9f are removed from the rollers 51A and 51B, respectively. Furthermore, the flat surfaces 9A-c and 9B-e are also connected to the rollers 51.
A, 51B, the rollers 51A, 51B face the inclined surfaces 9A-f, 9B-f, and as shown in FIG. 4C, the clamp arm 25 is pulled by the spring 28 and rotates in the direction of arrow _A1 . , the clamper 26 moves downward, and the compact disk 4 is clamped onto the turntable 31 by the clamper 26 (second
(see figure).

Further, when the second rack 9A moves to the position shown in FIG. 4C, the switch SW ₄ is pushed by the rack 9A and turned on. Due to the operation of this switch SW ₄ , the loading motor 21 is stopped (the sixth
(see t ₃ in Figure C), the disk motor (not shown) starts and rotates (see t ₃ in Figure 6 J), and the compact disk 4 is rotated.
3. That is, the disk loading device 1
Following the completion of the disc loading operation, disc playback is automatically started.

Furthermore, due to the above movement of the second rack 9A,
Knob 15 is pulled into opening 7a.

Furthermore, as the clamp arm holding member 29 moves in the direction of the _arrow It rotates counterclockwise, and the bent portion 44a at the tip locks one end of the holding lever 43 and rotates it clockwise against the spring 46. Due to the rotation of the holding lever 43, the lock pawl 24 is released from the locking by the holding lever 43, and is rotated counterclockwise by the spring 52 to lock the gear 23.

As a result, when the compact disc 4 is loaded on the turntable 31, the disc playback device 1 is in the state shown in FIGS. 2, 4C, and 5B. That is, the movable base 5 is urged by the tensioned springs 14A, 14B to pull it into the playback device, presses against the front end surfaces of the guide rails 11A, 11B, and is firmly regulated in position. The second racks 9A, 9B are the springs 14A,
Although the tip is biased in _two directions by 14B,
Since the gear 23 is locked by the lock pawl 24, it is locked at the position moved in the direction of arrow _X1 . Since the second racks 9A and 9B are locked in the above positions, the disk tray 2 is stably maintained in the lowered position. Further, the knob 15 does not protrude beyond the decorative board 7, and the front surface 15a thereof is exactly flush with the front surface of the decorative board 7.
immersed in. In this state, the compact disc 4 is played back.

To remove the compact disc 4 from the playback device after playing the disc, operate the switch SW ₁ (see _t4 in FIG. 6A). This operation stops the disk motor (see t ₄ in Figure 6 J), energizes the plunger 40 (see t ₄ in Figure 6 B), and activates the switch.
SW ₁ and SW ₄ are ANDed and the loading motor 21 is started and reversed (t ₄ to _{t 7} in Fig. 6C)
reference).

When the plunger 40 is energized, the lock pawl 24 rotates clockwise in the state shown in FIG. 5B, and the lock on the gear 23 is released. When the motor 21 is reversed, each member operates in the opposite direction in the reverse order to that during the disk loading operation described above. That is, first,
The second racks 9A, 9B are mainly in tension due to the spring force of the springs 14A, 14B contracting.
It moves in the _X2 direction (see _t4 to _t6 in FIG. 6H), and the disk loading device 1 enters the state shown in FIG. 4B. When the second racks 9A, 9B move in the direction of arrow _X2 , the rollers 51A, 51B move on the inclined surfaces 9A-f, 9
Guided by B-f and further flat surfaces 9A-e, 9B-
e and roller locking pieces 29e and 29f, the clamp arm 25a rotates in the _two directions of arrow A against the spring 28, the clamper 26 moves upward and separates from the disc 4, and the clamp on the disc 4 is released. be done. Also, the side pins 17a to 17d are guided obliquely upward by the oblique elongated holes 9A-c, 9A-d, 9B-c, and 9B-d, and the disk tray 2 is guided by the guide pins 18a to 18d to move vertically toward the arrow Z. ₂
move upward in the direction. The disk tray 2 receives the disk 4 during upward movement, and the disk 4 is supported on the disk tray 2 away from the turntable 31. Further, the knob 15 protrudes from the decorative plate 7 in the direction of arrow _X2 . Further, the clamp arm holding member 29 moves in the direction of arrow _X2 following the movement of the second racks 9A and 9B, and the roller locking pieces 29e and 29
Even after f locks the rollers 51A, 51B and the second racks 9A, 9B move further in the direction of the arrow _X2 ,
The clamper 26 is held in the clamp release position. Also, due to the above movement of the member 29, the L-shaped lever 44
rotates clockwise, the holding lever 43 rotates counterclockwise, and becomes in a state where it can lock the bent arm portion 24a of the lock pawl 24. The plunger 40 is brought into a de-energized state when the second rack 9A moves and the switch SW ₄ is turned off (see _t5 in FIGS. 6B and F), but the lock pawl 24 is released from the holding lever 43. The gear 23 is locked and held in an unlocked state.

Subsequently, in addition to the second racks 9A, 9B, the first racks 8A, 8B are connected to the motor 21, respectively.
(gears 19A, 19B) (see _t6 to _t7 in FIGS. 6G and H), the moving base 5 moves in the direction of arrow _X2 , and the disk tray 2 moves as shown in FIGS.
As shown in FIG. A, the disk 4 is projected forward of the playback device and removed from the playback device. The loading motor 21 has switch SW ₂ set to the first rack 8A.
It stops when it detects the completion of movement (see _t7 in Figures 6C and D).

Next, the operation and operation for removing the compact disc when the power to the disc playback device is off will be described.

In this case, the eject knob 45 is pressed in the state shown in FIGS. 2 and 5B. By this operation, as shown in FIG. 5C, the operating lever 4
₁ moves in the direction of arrow
pushes the bent arm 24a of the lock pawl 24, which rotates clockwise and the gear 23 is unlocked.

When the gear 23 is unlocked, the spring force of the springs 14A, 14B in tension causes the second racks 9A, 9B to move the pinion ₁ in the direction of arrow
While the loading motor 21 is forcibly rotated via 9A and 19B, the device 1 moves to a state where its movement is restricted, and the device 1 enters the state shown in FIG. 4B due to the spring force of the springs 14A and 14B. That is, the disk 4 is released from the clamp by the clamper 26,
It is in a state where it is supported on the raised disk tray 2, and the knob 15 is in a state where it protrudes from the decorative board 7. This protruding knob 15 functions as a handle, and the operator grasps the protruding knob 15 and pulls it in the direction of arrow _X2 . With this operation, motor 2
While forcibly rotating 1, the moving base 5 moves in the direction of the arrow.
The disc tray 2 is moved in the _X2 direction, and as shown in FIGS. 2 and 4A, the disc tray 2 and the disc 4 are pulled out of the playback apparatus, and the disc 4 is removed.

As shown in FIG. 5C, the operating lever 41 is a bent arm of an L-shaped lever 44 that rotates clockwise following the movement of the second rack 9A (clamp arm holding member 29). The cutout portion 41b is retained by the portion 44a and locked in the moved position.
Therefore, the lock pawl 24 is held in the clockwise rotating position via the lock release lever 42, and the gear 23 is held in the unlocked state. In addition, the operation lever 4
The locked state of 1, ie, the unlocked state of the gear 23, is released the next time the disk 4 is loaded.

Note that, as shown in FIG. 5A, before loading the disk and during the disk loading operation, the operation lever 41 is
The tip of the lever 44 is locked by the bent arm 44a of the L-shaped lever 44, so that the eject knob 45 cannot be pushed in, thereby preventing erroneous operation.

Further, the above-mentioned disk loading device 1 is configured so that disk loading can be carried out manually. Manual disk loading operation is shown in Figure 1, Figure 4A,
In the state shown in FIG. 5A, operate a separately provided knob (not shown) to rotate the lock release lever 42 clockwise to release the lock by the lock pawl 24 of the gear 23. Push the plate 7 in the direction of _arrow , second rack 9A, 9
This is done by moving B. By this pushing operation, the disk 4 is loaded onto the turntable 31 in the same way as when using the loading motor 21 described above.

Therefore, the above-described disk loading device 1 can also be configured without the loading motor 21 and the gear train 22, that is, it can also be configured as a manually operated disk loading device.

Further, in the above device 1, the springs 14A, 1
If a spring with a large spring constant is used as 4B,
When the second racks 9A, 9B move in the direction of the arrow _X1 , the movable base ₅ is pulled by the springs 14A, 14B and moves in the direction of the arrow Rack teeth are no longer required and the device is simpler. However, if the first racks 8A and 8B are used as in the above embodiment, the retracting operation of the movable base 5 can be performed reliably, and the spring constants of the springs 14A and 14B can be small. The load on the loading motor 21 is also small, and a small motor can be used as the loading motor 21.

As described above, according to the disk loading device of the present invention, the disk tray on which the disk is placed is movable between the ejection position where the disk can be attached and removed and the loading position where the disk can be rotated. The device includes a locking means for locking the disk tray so that it cannot be moved when the disk tray reaches the loading position, and a locking means for locking the disk tray so that it cannot be moved when the disk tray reaches the loading position, and locking means for locking the disk tray from the loading position by manual operation when moving the disk tray from the loading position to the ejecting position. The locking means is comprised of an operating means for setting the locking means in an unlocked state, and a holding means for holding the locking means in the unlocked state after being set in the unlocked state by the operation of the operating means, and the locking means is Since the disc tray is configured to be manually moved to the ejection position while held in the unlocked state, it is not possible to manually bring the disc tray locked at the loading position to the ejection position. However, if necessary, the disk can be manually removed. For example, even if a power outage occurs while the disk is loaded, the disk can be taken out, making it easier to use and preventing chains. Since the locking means is held in the unlocked position, it is possible to reliably perform the disc release operation by manual operation, and when the locking means is in the unlocked state, the disk tray in the loading position can be removed. By simply providing the lifting means, the disk tray can be brought to the ejecting position by simply moving further horizontally, and has the advantage that this can be done reliably by the disk removal operation and movement.
