The arm 58 is rotated by engaging with the edge of the arm 58 rotatably supported on the arm 58.

That is, the main slider 34 raises and lowers the disk position detecting member 26 shown in FIG. 2, but raises the disk position detecting member 26 when the carrier 20 is not in or out of the stocker 21. For example, if the carrier 20 is stored in the stocker 21 with the 8 cm disk displaced, the disk displacement detecting member 26 is prevented from rising by the displaced disk and the switch SW10 does not operate. it can.

The disc position detecting member 26 is formed so as to have a vertical stroke corresponding to the carrier 20 locked by the carrier pull-out member 36 and the loading hook 40, respectively. That is, the lifting stroke of the disk position detecting member 26 corresponds to two steps of the carrier.

When the disc position detecting member 26 is raised, the rod-like projections 26a and 26b are inserted into the center hole of the disc in the stocker and the hole 20c of the carrier 20, respectively. At this time, the rod-shaped projection 26a comes into contact with the switch operating rod 11 to operate the switch SW10, and the rod-shaped projection 26b comes into contact with the locking rod on the back surface of the stocker cover.

On the other hand, there is a situation where the stocker 21 is lifted and the carrier exists above the loading hook 40. In this case, the disc position detecting member 2

A bar-like projection 26a is provided in the center hole of the upper disc.
The rod-shaped protrusions 26b are not inserted into the holes 20c of the carrier 20, respectively. However, in such a situation, the switch operating rod 11 is inserted into the disk center hole above the loading hook, and the locking rod on the back surface of the car cover is inserted into the hole 20c of the carrier 20. Therefore, regardless of the position of the stocker 21, even if vibration is applied when the disk position detecting member 26 is raised, the carrier 20 and the disk placed on the carrier do not shift.

When the disk position detecting member 26 is lowered, the carrier 20 in the stocker 21 can be pulled out in each direction by the carrier pulling member 36 and the loading hook 40. Note that, when the disc position detecting member 26 is lowered, even if vibration is applied to the apparatus, the carrier extraction member 36 and the loading hook 40 are locked to the carrier 20 at a position where the bar-shaped protrusion 26b does not exist. Therefore, the carriers 20 do not shift.

The bar-like projection 26 of the disc position detecting member 26
If a taper is provided at the tips of a and 26b, a small displacement of the disc or the carrier can be corrected when the disc position detecting member 26 rises. In addition, it is possible to prevent the loading hook 40 or the carrier pull-out member 36 from coming into contact with the carrier when the stocker is moved up and down.

The shafts 69a of the elevating member 69 are engaged with the vertical guide grooves 1b of the main chassis 1 and the oblique elevating guide grooves 71b of the slider 71. Therefore, the lifting member 69 is attached to the main slider 3.
4 moves up and down through the gear 62 to the slider 71.
The mechanism chassis 70 is attached to the elevating member 69 via a spring and a damper.

A disk motor is fixed to the mechanism chassis 70, and a turntable 70a is fixed to a rotating shaft of the disk motor. Light Pickup 7
Reference numeral 0b is attached to the mechanism chassis 70 so as to be fed in a radial direction of the disk held on the turntable 70a. At a home position where the optical pickup 70b is farthest from the turntable 70a, a switch SW1 (not shown) is operated, and the home position of the optical pickup is detected.

When the mechanism chassis 70 is raised and the turntable 70a is raised, the disk on the carrier 20 is clamped by the turntable 70a and the clamper 10 and is driven to rotate by a disk motor. While the disk is rotating, the optical pickup 70b reproduces signals recorded on the disk by being sent in the radial direction of the disk. The member mounted on the mechanism chassis 70, the clamper 1
The playback mechanism is constituted by the drive mechanism of the mechanism chassis 70 and the drive mechanism.

The levers 66 and 67 are located close to the rotating member 65, and the respective holes 66a and 67a are fitted to the shaft (not shown) of the main chassis 1 and are rotatably supported by the main chassis 1. The rear end thereof is pressed against the cam 65b of the rotating member 65 by being urged by the tension coil spring 68. The ends of levers 66 and 67 are connected to switch S, respectively.
It contacts W4 and SW5.

The levers 66 and 67 swing around the axis fitted with the holes 66a and 67a according to the rotation of the rotating member 65. The levers 66 and 67 are connected to SW4
And SW5 is activated. The switch SW4 is turned on when the mechanism chassis 70 is raised or immediately before the mechanism chassis 70 starts to be lowered.
Turns on when is falling or just before starting to rise.

The chart in FIG. 9 shows the operation timing of each of the above members. The horizontal axes in FIGS. 7A to 7H are the main slider strokes and are scaled in the same manner. The main slider movement start point A indicates that the main slider is at the re-advance position, and the main slider movement end point B indicates that the main slider is at the last retreat position.

FIGS. 9B and 9C show the movement periods of the slider tray 31 and the carrier 20, respectively. The movement end point C of the slider tray 31 is earlier than the movement end point D of the carrier 20. FIG. 4D shows a state where the disk position detecting member 26 is moved up and down. FIG. 7E shows a state where the turntable is raised and lowered. The point G at the ascending position of the turntable is detected by the switch SW4 as described above. FIG. 7F shows the state of rotation of the cam gear 63. FIG. 7G shows a rotatable state of the members of the planetary gear mechanism. The carrier can be rotated before the point H, and the internal gear can be rotated after the point J.

FIG. 11H shows the movement of the stocker up and down and the movement of the loading slider. Before the carrier rotation limit H point, the stocker is moved up and down. Further, the loading slider is driven after the point F at which the disk position detecting member 26 is lowered.

Next, the operation of the disk reproducing apparatus having the above configuration will be described. The control circuit shown in FIG. 11 includes a microcomputer, a memory, an input / output interface, a driver circuit, and the like.
The signal from W10 and the signal from the reproducing unit are input,
The first motor 7 (M1) and the second motor 50 (M
2) and further outputs a play signal to the playback unit,
Further, it drives a disk motor and a pickup feed motor of the reproducing unit.

The apparatus is controlled by a control circuit in accordance with the operation of the switches SW1 to SW10 and the operation of keys (not shown) provided on the front panel of the housing. In the initial state, as shown in FIG.
And the loading hooks 40 are locked with the carriers 20, 20 in the stocker 21. The main slider 34 is at a position immediately before leaving the gear 62, and the gear 62 rotates clockwise as viewed from above.

Then, the turntable 70a is in an up state. The stocker 21 is at the lowest position. Further, the brake member 60 is moved rearward, and the protrusion 6
0c meshes with the internal gear 52 and stops it.
(At this time, the switches SW2, SW4, and SW8 are turned on, and the switches SW5 and SW7 are turned off.)
Only 4 can be rotated. Therefore, the stocker elevating slider 25 is moved by the second motor,
Is moved up and down.

In this state, the stocker 21 is raised and lowered,
The disc to be reproduced can be selected by adjusting the height of the carrier of the disc to be reproduced to the loading hook 40. That is, the stocker 21 is raised by the second motor, and the counter of the control circuit for storing the stocker position is counted up from 0 by turning on and off the switch SW6, so that the height of the carrier of the disk to be reproduced is adjusted to the loading hook 40. be able to. Further, the height of the carrier 20 for exchanging disks can be adjusted to the carrier drawer member 36.

First, the disk exchange will be described. Disc replacement can be performed in the above initial state, but can also be performed in a reproduction state in which the loading hook 40 moves the carrier 20 onto the turntable 70a. (At this time, the switch SW7 is turned on and the switch SW8 is turned on.) That is, as described above, when the main slider 34 is at the position shown in FIG. 5, the turntable 70a is in a raised state. If one of the carriers 20 is transferred onto the turntable 70a by the loading hook 40 before the turntable 70a rises, the disc on the carrier 20 is held by the turntable 70a and the clamper 10 to be in the reproduction state. Has become. Then, even if the main slider 34 moves forward (downward in the figure) from the position shown in FIG. 5, the state of the brake member 60 does not change and the gear 52 does not rotate, so that the reproduction state does not change.

After moving the stocker elevating slider 25 by the second motor 50 to elevate and lower the stocker 21 to adjust the height of the carrier 20 for exchanging disks with the carrier drawer member 36, the main slider 34 is moved by the first motor 7 Is sent forward.

In the initial stage of the movement of the main slider 34, the rotating member 35 shown in FIG. 3 is rotated clockwise as viewed from above, and its shaft 35a is in the J-shape of the right side chassis 2 shown in FIG. Since the groove 2a is engaged with a portion of the groove 2a in the direction perpendicular to the moving direction of the slider tray 31, the shaft 35a of the rotating member 35 is engaged.
Is prevented, and the slider tray 31 supporting the rotating member 35 does not move.

Similarly, the carrier extracting member 36 does not move in the early stage of the forward movement of the main slider 34. In the course of the forward movement of the main slider 34, the turning member 37 shown in FIG. 3 is guided by the recess 34c of the main slider 34 and turns, so that the shaft 37a of the turning member 37 enters the linear portion of the J-shaped groove 31a and the carrier. The drawer member 36 is driven forward. The carrier 20 is sent and the front end portion is the lower plate 31.
Are supported on the slider tray 31 on the tongue pieces 32a, 32a.

When the main slider 34 moves further,
The recess 34d of the main slider 34 engages with the shaft 35a to rotate the rotating member 35 counterclockwise. Then, the shaft 35
a engages with the portion of the J-shaped groove 2a extending in the direction of movement of the slider tray 31, so that the slider tray 31 is movable and the shaft 35a is pushed by the recess 34d so that the slider tray 3
1 moves forward, that is, in the direction in which it protrudes from the housing.

That is, the slider tray 31 moves from the position shown in FIG. 5 to the position shown in FIG. At this time, the switch SW3 is turned off. In the state shown in FIG. 6, the slider tray 31 protrudes from the housing, and the carrier 20 is also drawn out by the carrier draw-out member 36 so as to be integrated with the slider tray 31. In the state shown in FIG.
The disk on disk 0 can be replaced or the disk can be placed on carrier 20.

The storage of the carrier 20 in the stocker 21 is performed by reversing the motor 7. At this time, axis 3
5a is guided by the J-shaped groove 2a, and the rotating member 35 rotates clockwise. Therefore, after the slider tray 31 is retracted (detected by turning on the switch SW4), the main slider 34 can be further retracted. By repeatedly moving the stocker up and down to select a carrier, projecting the selected carrier out of the housing, and exchanging disks, the disks of all carriers can be exchanged.

Next, the operation of reproducing a disc of an arbitrary carrier from the initial state will be described. In the initial state shown in FIG. 5, after the stocker is moved up and down and the carrier 20 of the disc to be reproduced is adjusted to the loading hook 40, the main slider 34 is moved backward by the first motor 7, and the teeth of the gear 62 mesh with the rack 34b. Gear 62
And the cam gear 63 is rotated counterclockwise.

Then, the turntable 71a descends from the raised position, the brake member 60 moves forward, and the carrier gear 54
Is stopped. (This is detected when the switch SW5 is turned on.) FIG.
As shown in FIG. 9D, during the rotation from the point D to the point B in (f), the disk position detecting member 26 once rises and then descends.

Then, the internal gear 52 is rotated by the second motor 50, and the loading slider 9 is fed backward. The carrier 20 is turned on the turntable 7 by the loading slider 9 via the loading hook 40.
0a. (This state is detected when the switch SW7 is turned on.) Thereafter, the main slider 34 is rotated forward in a direction opposite to the direction in front of the first motor 7 until immediately before the main slider 34 is separated from the gear 62 (the position shown in FIG. 5). And the turntable 70a rises to clamp the disk and enter a reproducing state. (This state is detected when the switch SW4 is turned on.) In this state, the first motor 7 moves the main slider 34, and the disk can be replaced as described above. That is, in this apparatus, it is possible to change disks during reproduction.

The operation of returning the disk to the stocker 21 after the end of the disk reproduction is performed by rotating the first motor 7 and the second motor 50 in a direction opposite to that when the disk is mounted on the turntable. That is, first, the first
The main slider 34 is moved from the point D to the point B shown in FIG. 9 by the motor 7 (the main slider 34 is retracted from the position shown in FIG. 5. This state is detected when the switch SW5 is turned on. ) Then the second motor 50
5, the loading slider 9 is advanced from the reproduction position to the position shown in FIG. 5, and the carrier 20 is stored in the stocker 21. This state is the initial state shown in FIG. (This state is detected when the switch SW8 is turned on.) The position of the carrier of the disc being reproduced is stored by the control circuit, and the disc is controlled so that the disc is returned to the original position after the reproduction. .

As described above, the reproduction of the disk or the exchange of the disk in the stocker is performed. When the slider tray 31 is moved from the outside of the housing to the inside of the housing, that is, the carrier 20 is stored in the stocker 21 from outside the housing. After that, the main slider 34 is moved to the point G shown in FIG. (This is detected when the switch SW4 is turned on.) By moving the main slider 34 in this manner, the disk position detecting member 26 rises, but the disk position detecting member 26 moves to the position of the disk or carrier 20. If the upward movement is prevented by these members due to the displacement, the switch SW10 does not operate. At that time, the slider tray 31 is moved out of the housing. Then, after correcting the displacement of the disk, the slider tray 31 can be moved into the housing.

The carrier 20 is moved from the reproduction position to the stocker 21.
When the disk or the carrier 20 is displaced, the disc position detecting member 26 is similarly raised, and if there is a displacement of the disc or the carrier 20, the returned carrier 20 is discharged out of the housing. In this case, the main slider 33 is moved out of the housing after the height of the carrier to be discharged by lowering the stocker 21 by one step of the carrier is adjusted to the height of the carrier drawer member 36.

When the apparatus is stopped after the disk reproduction or disk exchange is completed, the disk position detecting member 2
6, the stocker 21 is lowered, and the disc position detecting member 26 is inserted through all the discs and carriers in the stocker. By doing this,
Even when a force is applied to the disk and the carrier in the stocker 21 by, for example, moving the apparatus, no displacement of the carrier or the disk occurs.

Next, with reference to FIGS. 12 to 16, the initialization operation at power-on will be described. This initialization operation assumes that the power is turned off in any state so as to cope with a sudden power failure or the like. However, in this apparatus, the stocker 2 is held in a state where the slider tray 34 protrudes out of the housing.
When the power is turned off, if the slider tray 34 protrudes out of the housing, the storage position of the carrier 20 on the slider tray in the stocker 21 is determined by stopping the stocker 21 at that time. The position of the slider tray 34 at the position coincides with the position where the carrier is returned.

FIGS. 12 and 13 show flowcharts of the initialization routine. FIGS. 14 and 16 are time charts when the input and output of each motor and each switch are reversed after each motor rotates forward and forward. . The symbol M
1 and M2 are the first motor 7 and the second motor 50
And SW2 to SW9 represent switches SW2 to SW9, respectively. The outputs of SW2 to SW9 which are not shown by solid lines mean that the output is not determined only by the state.

The initialization routine will be described with reference to FIGS. When the power is turned on, first, step S
At 1 and S2, the pickup feed motor is driven to initialize the pickup. With this operation, the pickup is sent to the home position.

Next, in step S3, the switch SW4 for detecting whether or not the slider tray 31 is closed is turned on (the output is at the ground level, and the same expression is used hereinafter. When the switch is off, the voltage is + 5V). If it is on, the main slider 34 is at the position (home position) where the slider tray 31 has been returned to the inside of the housing (home position), and the process proceeds to step S9. If not, the process proceeds to step S4.

In step S4, it is determined whether or not the switch SW5 for detecting turntable down is turned on. If it is on, the main slider 34 is at the rearmost position and the process proceeds to step S11. Move to S5. In step S5, it is determined whether or not the switch SW9 for detecting the presence or absence of the carrier at the position where the carrier 20 in the stocker 21 is drawn out of the housing is turned on. It is determined that it is in the middle of the rearmost position. In this case, the process proceeds to step S7. If it is not on, it is determined that the main slider 34 is located between the home position and the forefront position. In this case, the process proceeds to step S6.

In step S6, it is determined whether or not the tray close key of the operation key has been pressed, and the process proceeds to step S7 in the case where the tray close key has been pressed. In step S6 of this embodiment, if the slider tray is open when the power is turned on, the user presses the tray close key.
In this case, it is of course possible to automatically close the slider tray without pressing the tray close key by the user.

In step S7, the first motor is driven in the slider tray closing direction for a certain period of time, or the first motor is driven in the slider tray closing direction until the switch SW4 is turned on, and the flow advances to step S8. In step S8, it is determined whether or not the switch SW4 is turned on. If the switch SW4 is turned on, the process proceeds to step S9 since the slider tray 31 is in the housing. If not, the process proceeds to step S10.

In step S9, the first motor is driven in the tray closing direction until the switch SW5 is turned on, that is, until the main slider 34 comes to the rearmost position, and the process proceeds to step S11. In step S11 and subsequent steps, a process is performed when the main slider 34 is at the rearmost position.

First, in step S11, a switch SW for detecting that the carrier has been returned from the reproduction position to the stocker.
It is determined whether or not 8 is on. If it is on, the loading slider 9 is at the position where the carrier is returned to the stocker. In this case, the process proceeds to step S13. If not, in step S12, the second motor is driven in the carrier reproduction position feed direction until the switch SW7 is turned on, and the process proceeds to step S13.

In step S13, the first motor is driven until the turntable is raised and the switch SW4 is turned on, and the process proceeds to step SW14. Step S14
Then, the second motor is driven until the stocker reaches the home position (the lowest position) and the switch SW2 is turned on, and the process proceeds to step S15. In step S15, it is detected whether or not the switch SW8 for detecting that the loading slider 9 is at the position where the carrier is stored in the stocker is on. If the switch SW8 is on, the stocker is in a state where all the carriers are stored in the stocker. At the lowest position, the initialization routine ends.

If the switch SW8 is not turned on in step S15, the slider tray 31 is in the housing and the loading slider 9 is not in the carrier storage position.
In steps S16 to S23, an operation is performed in which the empty place of the stocker is searched for and the loading slider 9 stores the carrier 20 at that position.

First, in step S16, the lift counter for storing the stocker position is set to 6. Next, in step S17, the carrier 2 in the stocker 21 is
It is determined whether the switch SW9 for detecting the presence or absence of the carrier at the position where 0 is drawn out of the housing is turned on. If the switch SW9 is on, it is determined that the carrier is at the position where the carrier 20 is drawn out of the housing. to decide. Then, step S1
Move to 8. If it is not on, there is no carrier at a position where the carrier 20 is pulled out of the housing.

In this case, as described above, the loading slider 9 is moved one position from the position where the carrier 20 is pulled out of the housing.
Since the carrier is moved in and out of the shelf on the step, step S2
In step 1, the stocker is raised by one step by the second motor so that the empty space is adjusted to the height for storing the carrier by the loading slider 9, and the process proceeds to step S22.

In step S18, the stocker is raised by one stage and the lift counter is decremented until the switch SW6 is turned on and off once, and the flow advances to step S19. In step S19, it is determined whether or not the lift counter is 0. If not, the process from step S17 is repeated. If the lift counter is 0 in step S19, the carriers are stored in all the stages of the stocker, and the loading slider 9 is not at the carrier storage position.

That is, in this case, the loading hook 4
0 is out of the carrier, step S2
The processing of 0 or less is performed. In step S20, the stocker is lowered to the home position so that the space above the uppermost carrier is adjusted to the height of the loading hook 40, and the process proceeds to step S22.

In step S22, the turntable is lowered until the switch SW5 is turned on by the first motor, and the flow advances to step S23. In step S23, the loading slider 9 is driven in the carrier storage direction by the second motor until the switch SW8 is turned on. At this stage, all carriers are stored in the stocker,
Also, since the loading hook 40 is in the stocker, the stocker is lowered to the home position in step S11 and thereafter, and the initialization routine ends. This time, Y is determined in steps 11 and S15.

In step S10, it is determined whether or not the switch SW5 for detecting turntable down is on. If the switch SW5 is on, the main slider 34 is at the last position as shown in FIG. 31
Are present in the housing, steps S11 and subsequent steps are executed.

If the switch SW5 is not on, the slider tray is closed from the closed state and the first step is performed in step S9.
Despite driving the motor in the tray closing direction,
The main slider 34 is not at the last position. (FIG. 14
In this case, the carrier withdrawing member 36 is disengaged from the carrier and the carrier withdrawing member 36 collides with the carrier, or the stocker is moved while the carrier is withdrawn from the housing due to malfunction, and the carrier is returned from outside of the housing. This is the case when there is another carrier at the position to be changed. in this case,
The carrier pull-out member 36 cannot be retracted because of being hindered by the carrier. In other words, this is a case where the main slider 34 cannot retreat to the home position. In this case, step S
24 and below are executed. In a normal operation, the stocker 21 is not moved in a state where the carrier is pulled out of the stocker 21 by the carrier pull-out member 36.

In step S24, the slider tray 34 is driven in the open direction by the first motor until the switch SW3 is turned on. In step S25, the second motor is used until the switch SW2 is turned on (the stocker home position).
Then, the process goes to step S26.

In step S26, the lift counter is set to 6, and the flow shifts to step S27. Step S27
Then, it is determined whether or not the switch SW9 for detecting that the carrier is returned from outside the housing is turned on. If the switch SW9 is on, the carrier is located at a position to be returned from outside the housing.
Move to step S28. If it is not turned on, there is no carrier at the position returned from the housing, so steps S7 and subsequent steps are executed to return the carrier to that position. In this case, Y is determined in step S8 and steps S9 and subsequent steps are executed, and the initialization ends.

In step S28, the lift counter is decremented, the stocker is raised by one stage until the switch SW6 is turned on and off once, and the flow shifts to step S29. In step S29, it is determined whether or not the lift counter is 0. If it is not 0, the steps from step S27 are repeated. If it is 0, the carriers are stored in all the stages of the stocker. This is the case where it is not possible to retreat to the home position, and the carrier drawer member 36 has come off the carrier.

In this case, in step S30, the stocker is further raised by one step, and the steps below step S7 are executed by adjusting the space below the lowermost carrier described above to the height of the carrier drawer member 36. In this case, in step S8, Y
Is determined, and the steps after step S9 are executed, and the initialization is completed.

The initialization operation will be described separately for each case when the power is turned on.
