In addition, since the direction of the acting force of the torsion coil spring 356 is reversed in the middle of the pulling operation, the load applied to the second slide member 310 despite the fact that the second swinging body 350 rotates in the direction of the arrow 350B at a large angle. Will be negligible. Further, since the first rocking body 250 is also biased in the direction of the arrow 250A, the load on the first slide member 210 is small. Therefore, the driving means 2 in the pulling operation
The load on 81 is small. Further, as shown in FIG. 4A, the first rocking body 250 and the second rocking body 3 are
50 is located outside the projected area of the base body 100,
It is not located above or below the base body 100. Therefore, the first oscillating body 250 and the second oscillating body 350
Does not hinder the subsequent rise of the base body 100.

Next, the raising of the base body 100 and the holding operation of the disk 10 by the spindle motor 110 accompanying this will be described. After the disc 10 is drawn into the disc device 1 until the center 10a of the disc 10 and the center of the hub 110a coincide with each other, the first slide member 210 and the second slide member 210
Slide member 310 continues to move further. But,
As shown in FIGS. 4B and 4C, the pin 250
Since both s and the pin 350s are located in the linear portions of the cam grooves 210s and 310s, the first slide member 21
0 and the second slide member 310 continue to move so that the pin 250s is at the position of 250s' and the pin 350s is at the position of 350s.
Both the first oscillating body 250 and the second oscillating body 350 stop rotating in the state shown in FIG. 4A until the position s ′ is reached.

On the other hand, as shown in FIGS. 5 (a), 5 (b) and 5 (c), the first slide member 210 and the second slide member 310 continue to move, whereby the base body 100 rises, Turn the disk 10 into the turntable surface 1
The operation of mounting on 10b is performed.

As shown in FIG. 5A, while the first slide member 210 moves in the direction of arrow 10A and performs the above-described operation, the pins 132a and the pins 132a provided on the side surface of the base chassis 130 of the base body 100 are formed. 132b has moved in the horizontal portion of the cam grooves 210a and 210b provided on the side surface of the first slide member 210. Therefore, even if the first slide member 210 moves in the direction of the arrow 10A, the base chassis 130 is close to the bottom of the exterior housing 90 without changing the position in the height direction.

However, as shown in FIG. 4 (b), the first slide member 210 is further moved and the pin 250s is moved to 25
While moving to the position of 0 s', the first slide member 210
5a, the pins 132a and 132b are shown in FIG.
And as shown in (b), the cam grooves 210a and 21a
Move the inclined part of 0b. First slide member 210
The pins 132a and 132b are pushed by the side surfaces of the cam grooves 210a and 210b as the cam groove 2 moves.
In order to move 10a and 210b, the base body 100
Is pushed upwards.

As shown in FIG. 1A, cam grooves 310a and 310b are also provided on the side surface of the second slide member 310 and engage with the pins 133a and 133b of the base chassis 130. Therefore, although not shown, the second slide member 310 and the pins 133a and 133b also perform the same operation as described above. As a result, the base body 100 is lifted at the pair of opposite side surfaces,
It rises almost vertically to the bottom of the outer casing 90.

As shown in FIG. 5B, the base body 100
Hub 1 of spindle motor 110 as
10a fits into the center hole 10a of the disk 10. When the spindle motor 110 further rises, the disc 1
0 is sandwiched between the convex portion 90s provided on the ceiling of the outer casing 90 and the turntable surface 110b of the spindle motor 110, and the claw 110c of the spindle motor 110 holds the disk 10 on the turntable surface 110b. At this time, the tip of the hub 110a of the spindle motor 110 enters the hole 90h formed by the convex portion 90s. As a result, the disk 10 is placed on the turntable surface 110b.

As shown in FIG. 5 (c), when the pins 132a and 132b move to the ends of the cam grooves 210a and 210b, the base body 100 moves to the spindle motor 11.
The disk 10 held by 0 moves away from the convex portion 90s and moves down a little. The base body 100 is held at this height, the disk 10 is rotated by the spindle motor 110, and the optical head 120 is operated to perform the recording and reproducing operations with respect to the disk 10.

As described above, the second slide member 31
0 also operates similarly to the first slide member 210,
The base body 100 is supported at four points of pins 132a and 132b and pins 133a and 133b,
Raise and lower while maintaining a horizontal position.

As shown in FIG. 5 (b), the cam groove 210b
Since the base has only a bottom support, the base body 100
Is deformed, the pin 132b, which is the fourth point, is the first
There is a possibility that it will float up from the cam groove 210b. However, when the base body 100 moves up to the recording / reproducing position shown in FIG.
The leaf spring portion 285a that is elongated from 5 pushes down the base chassis 130, and the lower end of the pin 132b is along the bottom surface of the cam groove 210b (FIG. 1A). Therefore, the pins 132b are prevented from floating, and the base body 100 can be kept horizontal.

By the operation of the first slide member 210 from FIG. 5B to FIG. 5C, as shown in FIG.
It is slightly rotated in the direction of arrow 250B by 0 s.
Therefore, the pin 250d of the first rocking body 250 is separated from the disk 10. Further, since the slide connecting member 410 rotates in the direction of arrow 410A, the slide connecting member 41
The bent portion 410b of 0 is the disk positioning member 510.
Is pressed in the direction of arrow 10A, and pin 511a and pin 51
1b is slightly separated from the disk 10.

In the state shown in FIGS. 4 (a), 4 (b) and 4 (c), the pin 350d of the second oscillating body 350 has already been separated from the disk 10, and the pin 350d shown in FIG. In the state shown in a), the second oscillating body 350 does not move further. In the state of FIG. 5C or FIG. 6A, the second slide member 310 that has moved in the direction of arrow 10B has reached the position closest to the inside of the exterior housing 90, and has moved in the direction of arrow 10A. The first slide member 210 reaches the innermost position in the exterior housing 90. When the first slide member 210 pushes the detection switch 812, the driving means 281 stops.

In the state shown in FIGS. 5A to 5B, the base body 100 is raised and the disk motor 10 is held by the spindle motor 110 accordingly, and the state shown in FIG. 5B to FIG. 5C or FIG. In the state shown in (a), the base body 100 is lowered, and the disk 10 of the pins 250d, 511a, and 511b that have carried and positioned the disk 10
The operation of holding the disk is collectively referred to as "separation from" and stopping of the driving means 281. The base body 100 is shown in FIG.
Since the partition-shaped portion 130a of the base chassis 130 closes the disc insertion opening of the disc device when the disc is moved up to the position shown in (c), a disc may be mistakenly inserted from the outside while the spindle motor 110 is rotating. Absent.

Next, the disk 10 is moved to the spindle motor 11
The operation of releasing from 0 and ejecting the disc 10 from the disc device 1 will be described. These operations are generally performed in the reverse of the operation of inserting the disc 10.

In the state shown in FIGS. 6A and 7A, the operator issues a discharge command to the connector 8 shown in FIG.
11 is sent from the computer or an eject switch (not shown) provided in the disk device 1 is pressed, the driving means 281 starts driving and moves the first slide member 210 in the direction of arrow 10B, The second slide member 310 is moved in the direction of arrow 10A. These directions are opposite to those at the time of insertion. First slide member 2
With the movement of 10 and the second slide member 310,
The first oscillator moves once in the direction of arrow 250A,
The pin 250d of the first oscillating body 250, which has been separated from the disk 10, comes into contact with the disk 10. Similarly, since the slide connecting member 410 rotates in the direction of arrow 410B, the pin 511a and the pin 5 of the disc positioning member 510 are rotated.
11b contacts the disk 10. As a result, the disk device 1 becomes the state shown in FIG.

At this time, at the same time, the first slide member 210 moves in the direction of arrow 10B until the state shown in FIG. 7B, the cam groove 210a pushes up the pin 132a, and the base body 100 is again covered by the disk 10. It is pushed up until it contacts the convex portion 90s provided on the ceiling of the housing 90.

The first slide member 210 and the second slide member 310 continue to move, and the pins 250s and 350s move to the positions shown in FIGS. 4 (b) and 4 (c). At this time, the first oscillating body 250 and the second oscillating body 350 do not move and remain stationary at the position shown in FIG. 4 (a). On the other hand, as shown in FIGS. 7C and 7D, since the first slide member 210 moves in the direction of the arrow 10B, the pins 132a and 132b are pushed by the side surfaces of the cam grooves 210a and 210b, and the pins 132a and 132b move. Groove 21
The inclined portions of 0a and 210b are moved relative to each other. Along with this, the base body 100 descends and returns to the position before the disc 10 was inserted. In this process, the base body 100 tries to descend while holding the disc 10, but the outer edge of the disc 10 has pins 250d and pins 3d.
Since it is held at 50d, the disk 10 is warped as shown in FIG. 7 (c). However, the outer casing 9
Since the tip of the pin 91 protruding from the bottom of 0 pushes the disk 10 in the vicinity of the spindle motor 110, the claw 110c provided on the hub 110a of the spindle motor 110 is pushed by the outer periphery of the center hole 10a of the disk 10 and retracts. The hub 110a comes out of the center hole 10a of the disk 10. As a result, as shown in FIG. 7D, the state in which the spindle motor 110 holds the disk 10 can be released. The operation until the drive means 281 is started and the disk 10 is released is called a disk holding release operation.

Next, the ejecting operation of the disc 10 will be described. As shown in FIGS. 3B and 3C, as the first slide member 210 and the second slide member 310 move in the directions of the arrows 10B and 10A, respectively, the pin 350s of the second rocking body 350 moves. Cam groove 310
Proceed in s to reach the position shown in FIG. This time,
The second oscillator 350 rotates about the support point 350a in the direction of arrow 350A. As a result, the pin 350d at the tip of the second oscillating body 350 moves the disk 10 in the direction of arrow 1
Transport in the 0B direction.

Further, as shown in FIG. 3B, the pin 250s of the first rocking body 250 advances in the cam groove 210s. Along with this, the first oscillating body 250 rotates in the direction of arrow 250B around the support point 250a. The pin 250d at the tip of the first oscillator 250 rotates in the direction of arrow 250B while supporting the disc 10 in synchronization with the pin 350d at the tip of the second oscillator 350, and conveys the disc 10 in the direction of arrow 10B. To do.

When the second oscillating body 350 rotates in the direction of arrow 350A to the position shown in FIG. 3A, the contact between the one end 350e of the second oscillating body 350 and the one end 370e of the switch lever 370 is released, Switch lever 370 rotates in the direction of arrow 370B. As a result, the pressing of the detection switch 813 by the pin 370u of the switch lever 370 is released.

Since the detection switch 813 is released, the driving means 281 is stopped, and the second slide member 310 which has moved in the direction of arrow 10A reaches the innermost position in the outer casing 90 and stops. The first slide member 210 that has moved in the direction of the arrow 10B reaches the most front position in the exterior housing 90 and stops.

Further, FIGS. 4A and 4C to FIG.
During the discharging operation up to (a) and (c), the direction of the acting force of the torsion coil spring 356 reverses. Therefore, in the state shown in FIG.
It is biased in the direction of 50A. Therefore, even after the second slide member 310 is stopped, the second rocking body 350 overcomes the urging force of the first rocking body 250 on the arrow 250A and conveys the disc 10 in the direction of the arrow 10B. As a result, the second oscillating body 350 rotates to the state of 10E of FIG. 2A and the state of FIG. 2C. At this time, the first oscillating body 250 is pushed by the second oscillating body 350, and the broken line 250 '
Retreat to the position shown in. In this way, the disk 1
0 is ejected to a position where it can be taken out by the operator. The operation of ejecting the disc 10 by the second oscillating body 350 is referred to as a disc ejecting operation.

As described above in detail, in association with the series of movements of the first slide member 210 and the second slide member 310 driven by the drive means 281, the first oscillating body 250 moves the disc 10 to the disk 10. The pulling operation, the raising of the base body 100, and the accompanying operation of holding the disk 10 by the spindle motor 110 are sequentially performed. Also the first
Slide member 210 and second slide member 310
In conjunction with a series of movements in the opposite direction, the base body 100 is descended, the disc holding operation is accordingly released, and the disc is ejected by the second oscillating body 350.

In an emergency, the operator can force the disk 1
When it is desired to discharge 0, the meshing with the intermediate gear 282 or the other gear of the driving means 281 is disengaged by means not shown. Then, as shown in FIG. 6, the tip end 310f of the second slide member 310, which is closest to the front, is directly pressed from the outside, so that the second slide member 310 is moved to the arrow 1
The first slide member 210 is moved in the direction of arrow 10B in conjunction with this. Thereby, as described above, the disc ejecting operation can be performed to eject the disc.

According to the disk device 1 of the present invention, it is not necessary to use a roller as the disk carrying means. For this reason, only the part that defines the space for storing the disc so as to rotate needs to be wider than the disc, and the width of the other parts can be made narrower than the disc. For example, it is possible to use an exterior housing having a notch in the lower part of the space for storing the disc.

Further, the disc can be conveyed by only the two rocking members, the rocking member can be driven by the pair of slide members, and the base member including the spindle motor can be moved up and down. Therefore, the structure of the device can be simplified and the cost of the device can be reduced.

Furthermore, since most of the components can be arranged below the turntable surface and the disc can be held without using a clamper, a thin device can be realized.

As shown in FIG. 9D, drive means 281
Disk guide 3 which was evacuated outside until
90 starts the operation in the middle of the pull-in operation. Figure 11
As shown in (d), when the second slide member 311 moves in the direction of the arrow 10B, the pin 390m of the disc guide 390 is driven along the guide surface 311m.
For this reason, the disc guide 390 rotates in the direction of arrow 390B to the position shown in FIG. 11A and comes into contact with the disc 10. In this manner, the disc 10 is moved by the urging force of the third rocking body 540 in the direction of the arrow 540A so that the disc guide surface 390d of the disc guide 390 may be moved.
While the pin 250d of the first oscillating body 250 is pressed and positioned to two positions, the first oscillating body 250 causes the position shown in FIG. 11A, that is, the center hole 10a of the disk 10 to be the hub of the spindle motor 110. It is retracted to a position coinciding with the center of 110a.

Further, during this operation, in the second oscillating body 351, which is pushed by the disk 10 and rotated in the direction of arrow 351B, the direction of the acting force at the acting point 351b of the torsion coil spring 356 is reversed with respect to the supporting point 351a. To do. Therefore, the second oscillating body 351 is biased in the direction of the arrow 351B, and the bent portion 351i abuts on the stopper 740i on the supporting exterior housing 740 and is stopped. In this state, the pin 351d of the second swinging body 351 is located at a position separated from the outer circumference of the disk 10.

As described above, when the disc 10 is inserted into the disc device 2 because the disc guide 390 is retracted to the outside until the middle of the pulling operation, the disc 10 is first inserted into the guide body 720 on the right side in the insertion direction. Is regulated. Therefore, the disc 10 is inserted slightly closer to the left side than the center. When the disk 10 passes through the guide body 720 and contacts the pin 540d of the third rocking body 540, the driving means 281 starts operating,
The first oscillating body 250 starts to pull in the disc 10.
At this time, since the disc guide 390 also moves so as to regulate the insertion direction of the disc 10, the disc 10 is moved so that the insertion direction is corrected slightly to the right.
Be led to. Therefore, during the pull-in operation, the disc 1
The center of 0 follows the locus of arrow 10L shown in FIG.

As described above, since the space in the width direction of the disc device 2 is effectively used to convey the disc 10, the width of the disc device 2 can be reduced. Also the third
Since the oscillating body 540 is biased in the direction of the arrow 540A, even if the disc device 2 is installed vertically with the direction of the arrow 10A downward, it has a sufficient size that the weight of the disc 10 is not lost. By force, the disk 10 is moved to the disk guide surface 390d and the pin 25 of the first rocking body 250.
It can be pressed against 0d.

Next, the raising and lowering of the base body 100 by the first slide member 211 and the second slide member 311 will be described. The operation in which the base body 100 rises, the center hole 10a of the disk 10 is inserted into the hub 110a of the spindle motor, and the disk 10 is placed on the turntable surface 110b is as shown in FIG. 5A in the first embodiment.
The operation is exactly the same as that described with reference to (b) and (c). During the holding operation of the disk 10 by the spindle motor 110, as shown in FIG. 11B, the pin 250s of the first oscillating body 250 is located in the linear portion of the cam groove 211s. Further, as shown in FIG. 11C, the pin 351p of the second rocking body 351 is separated from the step portion 311p of the second slide member 311. Since the disk 10 does not move, the third rocking body 540 is shown in FIG.
It is stopped in the state of (a).

As with the first embodiment, after the disk device 2 is in the state shown in FIGS. 5A and 5B,
In the state from (b) to (c), in the first slide member 211, as shown in FIG. 12 (b), the pin 250s of the first rocking body 250 moves in the direction of the arrow 10A in the cam groove 211s. Is slightly rotated in the direction of arrow 250B. Therefore, as shown in FIG. 12A, the pin 250d of the first rocking body 250 is separated from the outer periphery of the disk 10. Further, as shown in FIGS. 12A and 12C, since the guide surface 311m of the second slide member 311 moves in the direction of the arrow 10B, the pin 390m of the disc guide 390 moves along the unevenness of the guide surface 311m. Move in the direction of arrow 10B. Therefore, the disc guide surface 390d of the disc guide 390 is separated from the outer periphery of the disc 10. Since the slide coupling member 410 rotates in the direction of arrow 410A in conjunction with the movement of the first slide member 211, the end portion 410b pushes the pin 540b of the third rocking body 540 to move the third rocking body 540 to the arrow 540B.
Rotate in the direction. Therefore, the pin 540d is also separated from the outer periphery of the disc 10.

As shown in FIG. 12A, the first slide member 211 moved in the direction of arrow 10A by the distance A from the initial state shown in FIG. The second vehicle that has reached and has moved in the direction of arrow 10B.
The slide member 311 reaches the frontmost position within the exterior housing 90. As shown in FIG. 12D, the pin 380
t is guided by the cam groove 311t of the second slide member 311 to rotate in the direction of arrow 380B, and the attachment completion detector 8
Press 15. As a result, the driving means 281 stops, and the first slide member 211 and the second slide member 311 also stop.

As described above, when the disc 10 is inserted, the first oscillating body 250 contacting the disc 10 is inserted.
250d, the pin 540d of the third rocking body 540, and the disc guide surface 390d of the disc guide 390.
Is separated from the disk 10, so that the disk 10 can be rotated by the spindle motor 110. In this state, the disk device 2 can rotate the disk 10 by the spindle motor 110 and record information on the disk 10 or reproduce information from the disk 10 by the optical head 120 on the base body 100.

Next, the spindle motor 1 of the disk 10
The releasing operation from 10 and the ejecting operation of the disk 10 will be described. From the states of FIGS. 12A, 12B, 12C, and 12D, an eject command for the disk 10 is sent from the computer via the connector 811, or an eject switch provided on the front bezel 80 by the operator. 81 (Fig. 8
When (b)) is directly pressed, the driving unit 281 starts driving, the first slide member 211 moves in the direction of arrow 10B, and the second slide member 311 moves in the direction of arrow 10A. That is, the first slide member 211 and the second slide member 311 start moving in the direction opposite to that at the time of insertion. Then, as shown in FIG. 11A, the disc 1
The pin 250 of the first oscillating body 250 separated from 0
d, the disc guide surface 390 of the disc guide 390
d and the pin 540d of the third rocking body 540 contact the outer periphery of the disk 10 to hold the disk 10.

Then, the first slide member 211 and the second slide member 311 are moved to move the base body 1
00 once rises and then descends, and the disk 10 is detached from the turntable surface 110b. This disc 1
The release operation of 0 is the same operation as the first embodiment described with reference to FIGS. 7A to 7D.

Next, the ejecting operation of the disc 10 following the releasing operation of the disc 10 will be described. As shown in FIGS. 10A and 10C, the pin 351 of the second rocking body 351.
p is the second slide member 3 that moves in the direction of arrow 10A.
The stepped portion 311p of 11 pushes in the direction of arrow 10A, and the second oscillating body 351 rotates in the direction of arrow 351A. As a result, the pin 351d of the second swinging body 351 is
The disk 10 is pushed in the direction of the arrow 10B, and the disk 10 is conveyed in the ejecting direction while the left and right directions are restricted by the guide bodies 720 and 730. Also at this time, FIG.
As shown in (b), the pin 250 of the first rocking body 250
The s is guided by the cam groove 211s that moves in the arrow 10B direction, so that the first swinging body 250 rotates in the arrow 250B direction. Therefore, the pin 250d rotates while being separated from the outer periphery of the disc 10 so as to escape from the ejected disc 10. During the transition from the state of FIG. 12A to the state of FIG. 10A, the direction of the acting force of the torsion coil spring 356 is reversed, and in the state of FIG. Is urged in the direction of arrow 351A. In this way, the disk 10 is transported by the second rocking body 351.

When the first slide member 211 and the second slide member 311 are further moved, the disk device 2
13 (a), 13 (b), 13 (c) and 13 (d). As shown in FIG. 13A, the second slide member 311 that has moved in the direction of arrow 10A reaches the innermost position in the exterior housing 90, and the state shown in FIG. The first slide member 211, which has moved in the direction by the distance A + α, reaches the frontmost position in the exterior housing 90. As shown in FIG. 13D, the pin 380t of the detection lever is connected to the cam groove 311 of the second slide member 311.
It is guided by t and rotates in the direction of arrow 380B to push down the attachment completion detector 815. Thereby, the driving means 281
Reverses the drive rotation direction and starts rotation in the opposite direction.

At this time, the second oscillating body 351 has the same structure as in FIG.
As shown in FIG. 13C, since the pin 351p is completely pushed in the direction of the arrow 10A by the step portion 311p of the second slide member 311, as shown in FIG. The reference numeral 351d ejects the disc 10 to a position where the central hole 10a is substantially outside the front bezel 80. As described above, not only the biasing force of the torsion coil spring 356 but also the driving of the second slide member 311 causes the second rocking body 351 to reliably eject the disc 10. Therefore, even if the disc device is installed vertically with the direction of the arrow 10A as the floor surface, the disc 10 is stably ejected at a predetermined rate, for example, until the central hole 10a is exposed to the outside of the disc device 2. can do. The mounting completion detector 815 also serves to detect the completion of ejection of the disk 10 as described above.

Further, as shown in FIG. 13A, since the end portion 410c of the slide coupling member 410 pushes the pin 540c of the third rocking body 540, the third rocking body 540 is indicated by the arrow 5 in FIG.
Rotate in the 40A direction. As a result, the third rocking member 54
The 0 pin 540u depresses the pull-in start detector 814.
Originally, the third swinging body 540 was biased in the direction of the arrow 540A, but since the slide connecting member 410 surely presses the pull-in start detector 814, even if the pull-in start detector 814 is pressed, the load. Even if it is too large, or if the third oscillating body 540 is partially twisted and becomes difficult to rotate, it is possible to reliably return the third oscillating body 540 to the initial position and press down the retraction start detector 814. It can be carried out.

In the state shown in FIG. 13 (a), the first slide member 211 moves in the direction of arrow 10A by the drive means 281 whose drive rotation direction is reversed. And
As shown in FIG. 9A, the first slide member 211 moves in the direction of arrow 10A by the distance α, and the second slide member 311 moves in the direction of arrow 10B. The direction of these movements is opposite to that. First slide member 21
When the end 211u of No. 1 pushes down the initial state detector 816, the driving unit 281 stops. FIG. 13 (a),
From the states shown in (b), (c) and (d), FIG.
When shifting to the states shown in (a), (b), (c), and (d), the stepped portion 311p of the second slide member 311 also moves in the direction of the arrow 10B, but the second rocking body 351 is It is biased in the direction of arrow 351A by the biasing force of the torsion coil spring 356, and the bent portion 351o is moved to the disc guide 39.
It is stopped at the position where it abuts 0. Therefore, in FIG.
As shown in (c), the pin 351p does not follow the step portion 311p, and only the second slide member 311 moves in the direction of the arrow 10B with the second swinging body 351 left at the stop position. In this way, the second rocking body 351 is moved to the arrow 351A.
By staying in the disc 10 ejecting position while being biased in the direction, the protrusion 351g can serve as a guide for the disc 10 to be inserted next.

In this way, when the disc is inserted, the first slide member 211 is moved by the arrow 1 by the drive means 281.
The second slide member 311 moves by the distance A in the direction of 0A, and moves in conjunction with the direction of the arrow 10B. With these operations, the first rocking body 250 pulls the disc 10 from the insertion position to the rotation position of the disc 10. In addition, the base body 100 rises and the spindle motor 110
The disk 10 is placed on the turntable surface 110b.

On the other hand, when the disk 10 is ejected, the first slide member 211 moves in the direction of arrow 10B by the distance A + α, and the second slide member moves in the direction of arrow 10A. Along with this operation, the base body 100 descends, and the disc 10 separates from the turntable surface 110b. In addition, by the second swinging body 351, the disc 1
0 is discharged from the rotation position to the discharge position. After ejecting the disc 10, the first slide member 211 again moves in the direction of arrow 10A by the distance α, and the second slide member 311 also moves in the direction of arrow 10B again to return to the initial position. At this time, the second oscillating body 351 biased in the disc ejecting direction does not follow the movement of the second slide member 311 in the direction of the arrow 10B and remains at the disc 10 ejecting position.

Instead of the regular size (for example, 12 cm in diameter) disk 10 described above, a regular size of about 3 is used.
The second disk 11 with a diameter of up to 2/2 (for example, 8 cm in diameter) has a front bezel 80 as shown in FIG. 9 (a).
A case will be described in which the disc is mistakenly inserted by the operator through the disc entrance 80w. When the second disc 11 is inserted from the left side or the center of the disc entrance 80w, the action of the torsion coil spring 356 is reversed in the second oscillator 351 even if the entire second disc 11 is pushed. It is configured not to rotate until. For this reason, when the hand is released, the second disc 11 is rotated by the torsion coil spring 356 and the arrow 351 of the second rocking body 351 is moved.
It is pushed out by the rotational force in the A direction. Further, from the right end of the disc entrance 80w, the guide surface 720d of the guide body 720
Even when the second disc 11 is inserted along the second disc 11, the outer edge of the second disc 11 always contacts the bend 351i of the second rocking body 351 or the pin 351d, and the second rocking body 351 is moved in the direction of the arrow 351B. Since it rotates, it is ejected by spring force. In this way, even if a disc smaller than the regular size is inserted, there is almost no possibility that such a disc will enter the disc device 2 and cannot be taken out.

Whether the disk device 2 is installed vertically in the direction of the arrow 10A or vertically with its left and right side surfaces facing downward, in the process of transporting the disk 10, near the entrance. Second swing body 351 and guide body 72
0, 730, and in the vicinity of the center, the disc guide 390, the third oscillating body 540, and the first oscillating body 250 always support the disc 10 being conveyed, so that the disc 10 can be stably conveyed. To be done.

As described above, according to the disk device 2,
The insertion guide and the projecting portion of the second rocking member prevent the disc from being scratched at the time of insertion, and the slide member can reliably and stably eject the disc. In addition, the number of detectors is not increased by combining one detector to detect two states, and the weight of the disk device can be reduced by the supporting exterior housing. Even if a small diameter disc is inserted, it can be ejected by a spring force, and the width of the disc device can be reduced by moving the disc guide. Further, since the disc is always supported during the transportation process, stable disc transportation can be performed even when the disc device is installed vertically, and the initial state can be surely detected.

In the first and second embodiments, the base body was moved up and down by the first and second slide members. However, the base body does not necessarily have to be moved up and down by the first and second slide members. For example, a third slide member having a cam groove that interlocks with the first or second slide member and engages with a protrusion provided on the side surface of the base body is provided, and the first or second slide member and the third slide member are provided. The base member may be moved up and down by the slide member. Such a third slide member may be provided on the side surface of the base body so as to sandwich the base body with respect to the first or second slide member, or in the vicinity of two adjacent side surfaces of the base body. You may provide a 1st or 2nd slide member and a 3rd slide member.

Further, although the entire base body is moved up and down to mount the disc on the turntable surface and detach the disc from the turntable surface, these operations are performed on one side surface of the base body. It can also be done by raising and lowering. Specifically, one side surface of the base body is moved up and down by the first slide member or the second slide member, and the base body is rotatably supported on the side surface facing the raised and lowered side surface. With such a structure, as the slide member moves, the turntable surface rotates about the axis that supports the base body and tilts or becomes parallel to the disc. Therefore, it is possible to place the disc on the turntable surface and detach the disc from the turntable surface.

[0129]

According to the present invention, since the roller is not used as the disk conveying means, the width of the disk device can be reduced. Further, since the disc is carried only by the two oscillating bodies, and moreover, the two oscillating bodies are driven by the slide member and the base body is driven up and down, the structure of the disc device can be simplified. A low-cost and lightweight disk device can be realized.

By moving the side surface of the base body up and down by the slide member, the disk can be placed on the turntable surface or detached from the turntable surface without using a clamper. In particular, when the spindle motor and the base body are supported from both sides by the pair of left and right slide members which are interlocked with each other and moved up and down without tilting, the disc holding operation and the rotating operation can be performed more stably.

Also, the pair of slide members, the first and second slide members.
By arranging the oscillating body and the slide connecting member outside the projected area of the base body, most of the components can be arranged in a plane below the turntable surface.
Moreover, the clamper can be removed from the upper surface of the disk by using the self-holding type spindle motor.
As a result, the disk device can be made thin.

By arranging the base member on the front side of the device, the circuit board and the connector for connecting to the outside of the device can be arranged at the back of the device, so that the connection to the outside can be easily performed and the area of the circuit board can be reduced. Can be made smaller.
Further, by making the moving direction of the slide member substantially the same as the disc transport direction, the slide member can be forcibly moved from the outside, and the disc can be easily ejected in an emergency.

Further, a cutout shape is provided on the outer casing of the disk device to further reduce the size, and even in this state, by engaging a part of the first oscillating body with the guide portion of the outer casing, The rocking body can rotate without floating. Further, by using the reversing spring for the operation of the second oscillating body, the driving load for driving the second oscillating body is small even though the second oscillating body rotates at a large angle. You can

Further, even if the base body is deformed, the plate spring portion provided on the drive means support body corrects it, so that the base body can be kept horizontal and the disk can be held and rotated stably. You can Further, when the disc is rotating, the partition-shaped portion of the base body closes the disc insertion opening, so that the disc will not be erroneously inserted.

Further, the insertion guide and the projecting portion of the second oscillating member make it possible for the operator to insert the disc.
Since the disc is guided so as not to collide with the parts on the base body, the disc is not damaged.

Further, since the second slide member surely pushes down the second oscillating body until the disc is ejected, the disc can be stably ejected by a constant amount. Further, after the ejection, the second slide member is returned by a certain amount while leaving the second rocking body, so that the protrusion of the second rocking body can guide the disc. Further, the disk mounting completion detector and the ejection completion detector both serve to enable the above operation without increasing the number of detectors.

Further, since a strong supporting exterior housing having a bent portion is attached to the exterior housing, it contributes to the reinforcement and weight reduction of the disk device.

Further, even if a disc smaller than the regular size is inserted, it is always ejected by the spring force of the second rocking body.

Further, by moving the disc guide between the positioning position and the retracted position, the disc transport locus can be optimized and the disc device width can be reduced. Further, since the disc is always supported during the disc transport process, the disc can be stably transported even when the disc device is vertically installed.

Further, in the disc ejecting operation, the slide connecting means always pushes the third rocking body to return it to the initial position, so that the pressing of the initial state detector by the third rocking body is surely performed to prevent erroneous detection. You can
