The recessed surface 14 is provided in the vicinity of the support shaft 41h as shown in FIG.
A spring receiver 44 as shown in FIG. A spring 45 is mounted between the spring receiving portion 42a of the stopper 42 and the spring receiving 44 as shown in FIG. Therefore, the stopper 42 is always biased in the clockwise direction by the spring 45. When the cam 35 is applied with a rotational force of a certain amount or more, the stopper 42 tilts counterclockwise against the biasing force of the spring 45. As a result, the cam 35 disengages from the stopper 42 and rotates.

Further, as shown in FIG. 25, the recessed surface 14 is provided with two position detecting members 46 and 47 on the right side thereof.
The position detector 46 is arranged so that the operator 46a thereof can come into contact with the operating rod 30 of the gear 24. In addition, the position detector 4

As shown in FIGS. 23 and 24, 4 to 106 are provided so as to protrude downward. Detection pieces 104 to 106
Is set to be longer than the contact piece 103, as shown in FIG.

Then, the tip of the contact piece 103 comes into contact with the lane surface 86 of the tray 70 to smoothen the rotation of the CD tray 95. The tips of the detection pieces 104 to 106 move in the groove 85 of the tray 70.

When the detection pieces 104 to 106 pass between the light emitting element 88 and the light receiving element 89, the CD tray 95
The position states of the mounting surfaces 97 to 99 are detected. In the state of FIG. 22, the detection piece 104 for detecting the first mounting surface 97 is arranged on the front side, and the second mounting surface 9 is arranged on the left side.
A detection piece 105 for detecting 8 and a detection piece 106 for detecting the third mounting surface 99 are arranged on the right side. Note that, as shown in FIGS. 22 and 23, the CD tray 95 has protrusions 97 a to slightly higher than the mounting surfaces 97 to 99 on the outer peripheral portion between the notch 100 and the recess 101.
99a is formed respectively. This protrusion 97a-99a
Is for restricting the movement of the CD 9.

Next, the operation of the disk device of this example will be described. First, the operation of the drive mechanism for pulling out the tray 70 from the cabinet 10 will be described with reference to FIGS. 1, 2 and 25.

In the disk device of this example, the tray 70 can be pulled out in the stopped state, and the CD 9
Tray 70 even in the chucking state, that is, the playing state
It is designed to be able to pull out. Therefore, in this example, as shown in FIG.
Opening and closing buttons 66 and 67 are located on the right side of the upper edge of the front panel 65
Individually distributed. The open / close button 66 is for pulling out the tray 70 in the stopped state. The open / close button 67
This is for pulling out the tray 70 in the play state.

When the open / close button 66 is pressed, the motor 17 rotates to rotate the gear 24 in the clockwise direction.
At this time, the gear 24 meshes with the gear portion 39 of the cam 35, but does not mesh with the gears 31 and 32. When the gear 24 rotates, the cam 35 rotates counterclockwise to release the chucking, and then the gear portion 25 of the gear 24.
And the small-diameter gear portion 31b of the gear 31 mesh with each other to form the tray 70.
Move forward. Therefore, the tray 70 is pulled out to the state shown in FIG. At this time, the gear 33
Rotates in the counterclockwise direction because it meshes with the gear portion 93 of the tray 70, but the gear 32 rotates in the clockwise direction.
Does not mesh with the gear 24 rotating in the clockwise direction, so there is no problem.

Further, since the gear 24 rotates in the clockwise direction, as shown by the chain double-dashed line in FIG.
Tilts the operator 46a of the position detecting body 46 in the counterclockwise direction. As a result, it is detected that the tray 70 is pulled out during the stop, and the detection signal is supplied to the control system.

Next, after the tray 70 is pulled out from the cabinet 10 to the state shown in FIG.
The D9 is placed on the placing surfaces 97 to 99 of the CD tray 95.
When the open / close button 66 is pressed again in this state, the motor 17 rotates to rotate the gear 24 in the counterclockwise direction. As a result, the gear 31 rotates in the clockwise direction, so that the tray 70 is pulled back backward and is housed in the cabinet 10.

To select CD9, three change buttons 68a to 68c arranged at the center of the upper end of the front panel 65 are selected.
Then, the two change buttons 68d and 68e (see FIG. 21) arranged substantially in the center of the right side of the front panel 65 are pressed. The change buttons 68a to 68c can directly select the mounting surfaces 97 to 99, and the change buttons 68d and 68e rotate the CD tray 95 by 1/3 in the forward and reverse directions to move the mounting surfaces 97 to 99. It is to move.

For example, when the CD on the first placement surface 97 is selected, the CD tray 95 in the state shown in FIG. 1 is rotated by 120 degrees, and as shown in FIG. It is necessary to make 97 correspond to the disk support 56 and the like. That is, the CD tray 95 is rotated to the reproduction position of the first mounting surface 97. The operation of the mechanism for rotating the CD tray 95 will be described below with reference to FIGS. 14 and 26 to 30.

First, when the change button 68a is pressed, the motor 71 rotates to rotate the gear 79 clockwise. At this time, as shown in FIG. 26, the gear 79 meshes with the gear portion 102 of the CD tray 95. In the CD tray 95, the point where the gear 79 and the gear portion 102 mesh with each other, the protrusion 82, and the center P are aligned with each other. Therefore, the gear portion 1 of the CD tray 95
The moment M generated in 02 acts on the support shaft 83. C
Since the D tray 95 is fixed to the projection 82 via the support shaft 83, the reaction moment Q with respect to the moment M is generated.
Occurs. Therefore, the CD tray 95 rotates clockwise as shown by the arrow R in FIG. This principle applies the planetary gear mechanism. The center P of the CD tray 95 rotates eccentrically with respect to the protrusion 82 arranged at the center of the lane surface 86, so that the CD
The tray 95 rotates while being eccentric along the wall portion 84 as shown in FIG. In this case, since the CD tray 95 rotates by being restricted by the wall portion 84, the support plate 81 rotates in the direction opposite to the R direction. Further, the CD tray 95 rotates while its center P is always eccentric with respect to the center of the tray 70 (projection 82) with a constant distance L.

In the CD tray 95 in the state shown in FIG. 1 in which the notch 100 of the second mounting surface 98 corresponds to the disc support 56, the protrusion 97 a of the first mounting surface 97 has the wall portion 84. It is in contact with the front side of the straight portion 84b. CD in this state
Regarding the positional relationship between the center P of the tray 95 and the protrusion 82, the center P is located on the front side of the protrusion 82.

When the gear 79 continues to rotate in the clockwise direction, the CD tray 95 rotates eccentrically in the clockwise direction to the state shown in FIG. And the CD tray 9
When 5 moves from the state of FIG. 1 to the state of FIG. 27, the CD tray 95 has a straight surface 84 a of the wall portion 84 on the peripheral surface between the first mounting surface 97 and the third mounting surface 99. Abut the center of.

In the state of FIG. 27, that is, in the CD tray 95 in which the notch 100 of the first mounting surface 97 is horizontal with the left and right direction of the tray 70, the protrusion 98 of the second mounting surface 98 is shown.
a is in contact with the straight portion 84d of the wall portion 84. In this state, the center P is located on the right side of the protrusion 82.

When the CD tray 95 continues to rotate while being eccentric, the CD tray 95 is projected on the second mounting surface 98 by the projection 9 of the second mounting surface 98.
The state shown in FIG. 28 is in which 8a abuts on the front side of the curved surface portion 84h of the wall portion 84. In this state, the center P is located on the rear side of the protrusion 82. When the CD tray 95 moves from the state of FIG. 27 to the state of FIG. 28, the protrusion 98a of the second mounting surface 98 of the CD tray 95 is the curved surface portion 84h of the wall portion 84.
Near the center of the wall and the protrusion 99a of the third mounting surface 99 is
The linear portion 84a of No. 4 abuts near the center.

Further, when the CD tray 95 rotates while being eccentric, the CD tray 95 is projected on the first mounting surface 97 by the projection 9 of the first mounting surface 97.
The state shown in FIG. 29 is in which 7a abuts on the linear portion 84c of the wall portion 84. In this state, the center P is located on the left side of the protrusion 82. When the CD tray 95 moves from the state of FIG. 28 to the state of FIG. 29, in the CD tray 95, the protrusion 97a of the first mounting surface 97 changes from the curved surface portion 84g of the wall portion 84 to the straight portion 84c. , And the protrusion 98 of the second mounting surface 98
The a rotates in a state of being in contact with the straight portion 84e of the wall portion 84.

When the CD tray 95 continues to rotate while being eccentric, the protrusion 99a of the third mounting surface 99 of the CD tray 95 comes into contact with the front side of the straight portion 84b of the wall portion 84 in FIG.
It becomes the state of. Then, when the CD tray 95 moves from the state of FIG. 29 to the state of FIG. 30, in the CD tray 95, the protrusion 99a of the third mounting surface 99 is the curved surface portion 84f of the wall portion 84.
Rotates in contact with.

When the selection operation described above is completed, the gear 24 shown in FIG. 2 rotates counterclockwise. The gear portion 28 of the gear 24 and the gear portion 39 of the cam 35 mesh with each other so that the cam 35
Rotates clockwise. When the cam 35 rotates, the support piece 54 shown by the solid line in FIG. 31 moves with its engagement piece 58 along the cam surface 37 of the cam 35. That is, the support 5
4 tilts clockwise about its axis 55 from the position indicated by the solid line in FIG. 31 to the position indicated by the two-dot chain line. As a result, the disc support 56 rises and lifts the CD 9 on the first mounting surface 97 of the CD tray 95. Therefore, the CD
As shown by the chain double-dashed line in FIG. 31, 9 is chucked in cooperation with the chucking member 53 to be reproduced.

There is some play in the gear teeth between when the tray 70 is stored and when the cam 35 is started. This is because when the cam 35 is started while the tray 70 is stored, the CD tray 95 rotates and the reproduction positions of the mounting surfaces 97 to 99 are displaced, so that this displacement is prevented.

At the end of rotation of the cam 35 and the tray 70
There is some play in the gear teeth between when the gear is pulled out. This is the tray 7 while the CD tray 95 is rotating.
This is to prevent 0 from being pulled out.

When the open / close button 66 is pressed in the play state, the gear 24 rotates in the clockwise direction, contrary to the above. Therefore, the support 54 tilts counterclockwise to release the chucking, and the CD 9 is returned to the original mounting surface 97.

Since the operating rods 38a and 38b of the cam 35 operate the operating element 47a of the position detecting body 47, the state of the support body 54 is detected.

In the disk device of this example, even if one CD is in the chucking state, the tray 70 can be pulled out so that another CD can be exchanged. The operation of the tray 70 in the chucking state will be described below.

When the open / close button 67 is pressed, the motor 17 rotates to drive the gear 24 in the counterclockwise direction. At this time, the gear 24 meshes with the gear 32,
The gear 31 and the gear portion 39 of the cam 35 do not mesh with each other. Since the gear 33 meshing with the gear 32 that rotates clockwise rotates counterclockwise, the tray 70 moves forward and is pulled out to the state shown in FIG.
At this time, since the gear 31 meshes with the gear portion 93 of the tray 70, it rotates in the counterclockwise direction.
Does not mesh with the gear 24 rotating in the counterclockwise direction, so there is no problem.

Further, since the gear 24 rotates counterclockwise, as shown by the chain double-dashed line in FIG.
0 tilts the operator 46a of the position detector 46 in the clockwise direction. As a result, it is detected that the tray 70 is pulled out in the play state, and the detection signal is supplied to the control system.

Even in the play state, the tray 70 is pulled out to the state shown in FIG. Therefore, in this example, the CDs mounted on the second or third mounting surfaces 98 and 99 can be replaced.

In this case, the tray 70 is pulled out from the cabinet 10 while the CD tray 95 does not rotate and the mounting surfaces 97 to 99 are held in the position state. That is, when the CD tray 95 is rotated and the tray 70 is pulled out,
C on the mounting surface 97-99 of the chucked CD9
D will be mounted, and one mounting surface 97-99
This is because the inconvenience that two CDs are overlapped occurs. Since the gear 24 is not meshed with the gear portion 39 of the cam 35 in this state, the chucking state is maintained.

After replacing the CD, the open / close button 67 is pressed again. As a result, contrary to the above, the gear 24 rotates in the clockwise direction to move the tray 70 to the cabinet 10.
Store inside. Even in this case, the tray 70 is housed in the cabinet 10 while the CD tray 95 does not rotate and the mounting surfaces 97 to 99 are maintained in the positional state.

Now, the operation of pressing the open / close buttons 66 and 67 in the play state or the stop state and the subsequent operation procedure will be described with reference to FIGS. 32 and 33.

First, the case where the open / close button 66 is pressed in the play state will be described. The operation in this case and the subsequent operation procedure proceed as in the conventional case, as shown in FIG. That is, when the open / close button 66 is pressed (step 120), the rotation of the disc support 56 is stopped and the rotation of the CD 9 is stopped (step 121). Then, after the support 54 for supporting the CD 9 is lowered and the chucking is released (step 122), the tray 70 is pulled out from the cabinet 10. That is, C
The tray 70 is pulled out while the D tray 95 rotates clockwise by 2/3 (step 123).

In this pulled out state, the CD 9 can be mounted, that is, newly mounted, or the replacement operation can be performed (step 124). Next, in the pulled-out state, the play button 69
When a is pressed (step 125), the CD tray 9
The tray 70 is accommodated while 5 is rotated clockwise by 1/3 (step 126). After the tray 70 is housed, the support 54 is lifted and chucked (step 12
7) and play is started (step 128).

Also, a change button 68 after the CD 9 is mounted
When pressing a to 68e (step 12
9), the CD tray 95 plays the selected CD at the playback position (mounting surface 9
The tray 70 is stored while rotating 7 to 99 to the position corresponding to the disc support 56 (step 13).
0). After that, as described above, after the support 54 is lifted (step 127), the play is started (step 1).
28).

Further, when the open / close button 66 is pressed after the CD 9 is mounted (step 131), the play button 6 is pressed.
Similar to the case of pressing the 9a, after the tray 70 is housed (step 132), the support body 54 rises to be in a chucking state (step 133). When the play button 69a is pressed in this state (step 134), the play is started (step 128). When the open / close button is pressed in the stop state, the same operation as described above is performed except for step 121. Also, tray 7
Rotating the CD tray 95 when opening and closing 0
This is because of the convenience of reproduction.

Next, as shown in FIG. 33, a case of pressing the open / close button 67 will be described. When the open / close button 67 is pressed (step 135), the microcomputer determines whether it is in the play state (step 13).
6). If it is determined that the player is not in the play state, the operation instruction of the open / close button 67 is not accepted (step 13
7), the tray 70 is not pulled out from the cabinet 10 (step 138). That is, the tray 70 is not pulled out even if the open / close button 67 is pressed in the stopped state.

When it is judged to be in the play state, the operation instruction of the open / close button 67 is received (step 139) and the state in which the CD tray 95 is not rotated, that is, the state of the mounting surfaces 97 to 99 of the CD tray 95 is maintained. In this state, the tray 70 is pulled out (step 140). In this case, the mounting surface 9
7 to 99 are released from the cabinet 10 as shown in FIG.
2, there are two mounting surfaces 98, 99 other than the mounting surface 97 corresponding to the disk support 56. Therefore, with the loading surfaces 98 and 99 opened, another CD 9 can be loaded in addition to the loading surface 97 corresponding to the CD 9 being reproduced (step 141).

When the open / close button 67 is pressed again after mounting another CD 9 (step 142), the tray 70 is stored (step 143).

Also, when the open / close button 66 is pressed (step 144), the tray 70 is stored. That is, if the tray 70 is pulled out regardless of the stop state or the play state, then the open / close button 66
The tray 70 can be stored by pressing. As a modified example, by pressing the open / close button 66 (step 144), the CD tray 95 is once stored, the play state is changed to the stop state, the chucking state is released, and then the CD tray 95 is pulled out again. You may.

Then, after the reproduction of the CD 9 being reproduced is finished, a play state is immediately set by selecting another newly installed CD 9. Therefore, another CD 9 can be played back quickly and smoothly. Even if the change buttons 68a to 68e are pressed after mounting another CD 9, the tray 70
Is not stored.

Incidentally, regarding the positional relationship between the center P of the CD tray 95 and the projection 82 in the state of FIG. 30, the center P is located on the front side of the projection 82 as in FIG. That is, CD tray 9
When 5 rotates 120 degrees, that is, 1/3, the support shaft plate 81 makes one rotation. This relationship also applies to the CD tray 95 and the gear 79. Therefore, the CD tray 9
When 5 rotates once (360 degrees), the gear 79 and the support shaft plate 81 rotate three times.

The state shown in FIG. 1 and FIGS. 27 to 30 shows the state where the CD tray 95 has rotated 1/3, but the subsequent rotation of the CD tray 95 is eccentric as described above. While being done.

FIG. 34 is an intermittent drawing of the locus of the detection piece 106 of the CD tray 95 moving on the groove 85 of the tray 70. Although FIG. 34 shows only the locus of the detection piece 106, the other detection pieces 104 and 105 also draw the same locus.

As described above, since the CD tray 95 rotates while being eccentric, the loci of the detection pieces 104 to 106 do not form a perfect circle with respect to the center (protrusion 82) of the tray 70. That is, the loci of the detection pieces 104 to 106 are partially curved, as shown in FIG. 34, and the width between the loci is expanded.

Therefore, in this example, a sensor (a light emitting element, a light receiving element) for detecting the rotational position of the CD tray 95, that is, the reproducing position of the mounting surfaces 97 to 99, is located at a portion corresponding to the narrow intersection T between the trajectories. ) 88 and 89 are arranged. Detection piece 104
Although ~ 106 pass through the four intersections T, in this example, as shown in FIG. 14, the sensors 88 and 89 are arranged at the portion corresponding to the intersection T on the right side of the notch 87. This sensor 88,8
As shown in FIG. 34, the light emitting element 9 and the light receiving element 89 are arranged so that the light emitting element 88 and the light receiving element 89 face each other.

FIG. 35 is a diagram showing a detected state of the reproduction position of the CD tray 95. FIG. 35 is a diagram in which the mounting surface 99 is arranged at a reproducing position, that is, at a position facing the disc support 56. Then, the detection piece 106 for the mounting surface 99
Passes through the light emitting element 88 and the light receiving element 89,
It is detected that the placement surface 99 is located at the reproduction position. It should be noted that when the other detection pieces 104 and 105 pass through the light emitting element 88 and the light receiving element 89, it is also detected that the mounting surfaces 97 and 98 are located at the reproduction position.

In the disk device of this example, the gear 24
Since the gears 31 and 33 and the cam 35 can be driven to rotate, the tray 70 can be driven by one motor 17.
It is possible to move in and out and tilt the support 54. Therefore,
In this example, since the number of parts (motor) can be reduced, the cost can be reduced.

Further, in the disk device of this embodiment, the rotation direction of the gear 24 when pulling out the tray 70 is different between the stopped state and the play state. Since the position detecting body 46 for detecting the rotation direction of the gear 24 is arranged corresponding to the operating rod 30 of the gear 24, the tray 70 is pulled out by one position detecting body 46 in either the stop state or the play state. It is possible to detect the high temperature with a simple configuration.

Further, in the disk device of this example,
The notch 100 is placed on the CD tray 95 from the outer periphery of the mounting surface 97.
The gear portion 102 is formed toward the center of
Since the diameter of the tray is smaller than the diameter between the notches 100, the tray 70 can be pulled out even in the playing state by arranging the chucking mechanism on the side opposite to the direction of pulling out the tray 70.

Further, in the disc device of this example, the open / close button 6 for pulling out the tray 70 in the stopped state is used.
Since the open / close button 67 for pulling out the tray 70 in the play state with 6 is arranged on the front panel 65, the tray 70 can be pulled out in the play state by pressing the open / close button 67, and the reproduction of the CD 9 being reproduced is completed. Then, by selecting the other CD that was newly installed, another C
D can be reproduced quickly and smoothly.

Further, in the disk device of this example,
A CD tray 95 which is rotatably arranged on the tray 70 and has three mounting surfaces 97 to 99 on which the CD 9 is mounted.
Are arranged so as to be eccentric with respect to the center (projection 82) of the tray 70, so that the CD tray 95 can be rotated while being regulated along the wall portion 84 of the tray 70. Therefore,
In this example, the width of the tray 70 in the left-right direction can be reduced, and the disk device can be downsized.

Further, in the disk device of this example, since the light emitting element 88 and the light receiving element 89 are arranged so as to face the portion corresponding to the narrow intersection T between the loci, the amount of light emission is small (the capacity is small). ) Even if the light emitting element 88 is used, the rotation position of the CD tray 95 (the reproduction position of the mounting surfaces 97 to 99) can be reliably detected, and the manufacturing cost can be reduced.

In the above-mentioned embodiment, the CD tray 95 is driven by the gear 79.
The driving method of the tray 95 is not limited to this, and the same can be applied by driving the support shaft plate 81, for example. Further, in the above-described embodiment, the mounting surface 97 formed on the CD tray 95.
The number of ~ 99 is three, but the number of mounting surfaces is not limited to this.

In the above embodiment, the tray 70 is used.
Although the two open / close buttons 66 and 67 are provided, the tray 70 may have only one open / close button. In this case, even if one open / close button is pressed, it is determined based on the signal indicating whether the CD 9 is in the play state or the stop state, and the tray 70 is pulled out in the corresponding state.

Further, although the above-mentioned embodiment is an example of a disk device for a compact disk, the present invention can be applied to a disk device using other disks. Further, the present invention can be applied to a disc device of a format capable of recording in addition to reproduction.

[0110]

According to the present invention, the third drive unit for driving the first tray in the play state and the second drive unit for driving the first tray in the stop state are provided.
Since the first tray can be pulled out or housed by being driven by the driving unit in the stopped state or the played state, the number of motors can be reduced and the manufacturing can be performed at low cost.
