That is, each of the guide rails 13 and 14 is moved by being given a driving force by a driving means such as a motor 26 for moving the tray 5. Note that the gear ratio of each float is set so that the guide rail 13.14 moves, for example, 120 mm while the tray 5 moves, for example, 300 mm. This driving means moves only the guide rail 14 backward after the tray 5 is housed in the player housing 2.

The configuration for this will be explained next.

The gear 19a1 shown in FIG. 2, that is, the gear that meshes with the rack part 17 fixed to the tray 5, can swing freely in the vertical direction (in the direction of arrow Z and the opposite direction) via a pin 34a on the small chassis 18. The swing plate 3 provided in

As shown in the figure, the gear 19a and the gear 19b, which is provided concentrically with the gear and meshes with the outer rack portion 14c of the guide rail 14, have a clutch portion 19c.

19d is formed, and both gears 19a and 19b are connected and separated by the swinging of the swinging plate 34. In addition, as shown in FIG.
) Coil spring 3 that gives a piascus toward
5 is provided. As shown in FIG. 4 (ω and (e)), an engagement plate 36 is attached to the front end of the guide rail 14, which has a rack portion 14c that meshes with the gear 19b, with a screw 36a. It is inserted into a long hole 14e formed in the rail 14 along the direction of extension of the guide rail, and the position of the engagement plate 36 can be changed by loosening this screw 36a. - When accommodated in the middle housing 2, this engagement plate 36

6 rotates, only the gear 19b rotates, and the gear 19a rotates.
will no longer rotate. The position of the engagement plate 36 is set so that the clutch parts 19c and 19d are disengaged at the same time that the tray 5 is housed in the player housing 2. That is, after the tray 5 is housed in the player housing 2, the driving means including the motor 26 moves only the guide rail 14 rearward. As will be described later, after the tray 5 is housed in the player housing 2, only this guide rail 14 is moved backward, and the disc clamp mechanism is activated.

As shown in FIGS. 1 and 8, a turntable 40 for rotating the disks 8 to 10 by being directly rotationally driven by a motor 39 is disposed within the player housing 2 so that its disk supporting surface faces downward. and
Further, it is attached to a sub-chassis 41 as a first supporting member fixed to the player housing 2. Note that the sub-chassis 41 is also shown in FIG. The tray 5 mentioned above moves back and forth (in the direction of arrow Y and in the opposite direction) parallel to the disk supporting surface of the turntable 40.

For example, a disk 10 carried by the tray 5 and housed in the player housing 2 parallel to the disk supporting surface of the turntable 40 is positioned directly below the disk supporting surface of the turntable 40 with a predetermined gap therebetween. The disk 10 located directly below the turntable 40 is lifted upward (in the direction of arrow Z) by the disk clamp mechanism and separated from the tray 5, and is clamped against the disk supporting surface of the turntable 40. .

As shown in FIGS. 1 and 2 and FIGS. 8 to 10, the disk clamp mechanism contacts the disk 10 and attracts the disk toward the disk supporting surface of the turntable 40 using the magnetic force of the magnet. A disk-shaped suppressing member 44 for pressing the disk, and a disk-shaped suppressing member 44 that is rotatably provided at its free end in the vertical direction (in the direction of arrow Z and the opposite direction), that is, in a plane perpendicular to the disk supporting surface of the turntable 40. and a support member 45 as a second support member rotatably supporting the pressing member 44 on the side opposite to the disk supporting surface of the turntable, and It has a spring member 46 (shown in FIG. 8) as a biasing means for biasing the support member 45. As shown in FIGS. 2 and 9, a lever member 47 is arranged in front of the pressing member 44, and is attached to the small chassis 48 via a support pin 47a so as to be freely rotatable in the vertical direction. . An intermediate member 47c is rotatably attached to the action point, that is, the rear end, of the lever member 47 by a pin 47b, and the intermediate member 47c engages with the free end of the support member 45 via the suppressing member 44. are doing.

A support shaft 50 parallel to the rotation center axis of the turntable 40 is provided on the small chassis 48 that supports the lever member 47 via a support bin 47a, and a disc-shaped cam member 51 rotates on this support shaft 50. It can be installed freely. 1st
As is particularly clear from FIG. 1, the cam member 51 has a spiral cam portion 51a formed around its rotational center axis, and the round bottle 47e protruding from the force point portion of the lever member 47 moves around the spiral cam portion 51a. It can smoothly slide into contact with the cam portion 51a. Cam member 5
1 is integrally formed with a gear 51b, which is connected to the right guide rail 14 via other two gears 52 and 53.
It meshes with the inner rack part 14b. That is, as the guide rail 14 moves backward, for example, as the motor 26 rotates, the cam member 51 rotates clockwise in FIG. 9, thereby causing the lever member 47 to rotate clockwise in FIG. The support member 45 is configured to rotate counterclockwise in FIG. 8, thereby clamping the disk. Also, when releasing the disk clamp, follow this process in reverse. Note that when clamping and releasing the clamp, the lever member 47 is moved by the spring member 46.
The pressing member 44 (shown in Figure M8)
is rotated while being pressed against the support member 45. Therefore, the pressing member 44 does not wobble while the supporting member 45 is rotating.

Here, the rotation support mechanism that rotatably supports the support member 45, which is a component of the disk clamp mechanism described above, will be described in detail.

As shown in FIG. 2, FIG.
A rectangular first opening 41a (shown in FIG. 10) is formed at the rear end of the opening 41a (shown in FIG. 10) through which a protrusion 45a that protrudes upward is inserted. This protrusion 45a has a circular second opening 4.
5b is formed. The second opening 45b is located above the first opening 41a, and the width dimension b (
(shown in FIG. 10). A spherical member 56 having a diameter larger than the width of the first opening 41a is arranged within the second opening 45b. Projection 4
A plate 57 is fixed to the lower end of 5a,
This receiver is located between the plate 57 and the sub-chassis 41.
The support member 45 is connected to the spherical member 56.
A coil spring 58 is provided as a biasing means for biasing in a direction approaching . Further, a circular opening 41b having an inner diameter larger than the width of the first opening 41a and smaller than the diameter of the spherical member 56 is formed in the center of the first opening 41a. The spherical member 56 is connected to this circular opening 41b.
, thereby causing the spherical member 56 to engage with the first opening 41a.
and is positioned so as not to shift with respect to the second opening 45b.

That is, the circular opening 41b serves as a positioning means for a spherical member 56 that is interposed between the support member 45 and the subchassis 41 and smoothly slides on the support member and the subchassis.
The support member 45 is positioned so that it does not shift in the rotational plane and in the three axial directions perpendicular to this, and the support member 4
5. By pressing the three members, the sub-chassis 41 and the spherical member 56, against each other by the coil spring 58, the gap between the three members is made zero within the rotation plane of the support member 45. With this configuration, the support member 4
5 rotates with high precision without rattling.

As shown in FIGS. 2, 8, and 9, a tilt chassis 61 is rotatably attached to the lower surface of the support member 45 via a bin 61b. In addition, bottle 61
b extends in the left-right direction (arrow X direction and the opposite direction). A carriage 62 carrying an optical pickup is disposed on the tilt chassis 61, and is guided by a guide shaft 63 to move along the recording surface of the disc 10 mounted on the turntable 40 and clamped. There is. Further, although not shown, a driving means for moving the carriage 62 is provided.

As is particularly clear from FIG. 9, the right rear end of the support member 45 that supported the tilt chassis 61 is
1 is provided with a motor 65 for rotating it.

A worm 65a is attached to the output shaft of the motor 65, and a worm wheel 66 meshed with the worm 65a is provided, and a pin 66a is provided on the worm wheel and protrudes from the center of rotation in a radial direction. is in smooth sliding contact with one free end of the tilt chassis 61.

Further, a spring member 67 is provided for imparting a bias tension to the tilt chassis 61. Therefore, as the motor 65 rotates and the bias applied by the spring member 67 causes the tilt chassis 61 to rotate, a tilt servo is performed.

The drive signal system of the drive means for rotating the support member 45 is provided with means for superimposing a signal representing the distance between the disk and the optical pickup, for example, a drive low frequency component.

Next, the configuration of the turntable 40 will be explained in detail.

As shown in FIG. 12, for example, an annular disk support member 76 made of rubber or the like is attached to the disk supporting surface of the turntable 40. As shown in FIG. In addition, a low friction member 78 made of a spherical member or the like that can freely protrude and retract from the disk supporting surface, and three coil springs 79 that provide a bias tension to the low friction member are arranged in the circumferential direction of the disk supporting surface. Arranged at equal pitch. This low friction member 78 comes into contact with the disk surface as the disk 10 mounted on the disk support surface of the turntable 40 approaches the disk support surface by a disk clamp mechanism including the pressing member 44. . As shown in FIG. 12, when the disk 10 is placed on the suppressing member 44 in an inclined state, the suppressing member 44 and the disk 1
0 approaches the turntable 40, the disc 1
0 comes into contact with the low friction member 78. As a result, the disk 10 is slightly moved in the radial direction while the inclination state on the pressing member 44 is corrected, and is returned to the normal horizontal state. In this state, the disc is clamped and the disc is centered with respect to the turntable 40 with high precision.

Next, the operation of the autoloading disc player having the above configuration will be briefly explained along with the playing procedure.

First, as shown in FIG. 1, the tray 5 is projected outside the player housing 2, and a disc 10, for example, is placed on the tray. Note that the operation of protruding the tray 5 out of the player housing is performed by following the reverse process of the retracting operation described below, and therefore will not be described in detail. Note that when the tray 5 protrudes outside the player housing 2, the guide rails 13 and 14 also protrude outside the player housing 2, and the tray 5 is firmly supported by the protruded guide rails.

After placing the disk 10 on the tray 5, switch group 7
When a command to start playing the disc is issued by operating the motor 26, the motor 26 starts rotating. As a result, the storage operation of the tray 5 and guide rails 13 and 14 is started. When the tray 5 is housed in the player housing 2 together with the guide rails 13 and 14, the engagement plate 36 (shown in FIG. 4, ω, (C)) provided on the right guide rail 14
engages the free end of rocker plate 34 (shown in FIG. 2), causing rocker plate 34 to rock upwardly.

As a result, as shown in FIG. 7, the clutch parts 19c and 19d of the gears 19a and 19b are disengaged, and the tray 5
stops, and thereafter, as the motor 26 rotates, the gear 19b
Only the guide rail 14 rotates, and only the guide rail 14 is moved backward. However, due to the stoppage of tray 5, the left guide rail 1
3 is not driven and stops. By moving only the guide rail 14 backward, the spiral cam portion 51a of the cam member 51 shown in FIG. 2 comes into sliding contact with the round bottle 47e of the lever member 47, and the lever member 47 rotates clockwise in FIG. It will be done. Therefore, the support member 45 is rotated counterclockwise in FIG. 8 by the lever member 47, and the suppressing member 44
rises and presses against the disk holding surface of the turntable 40 so as to lift the disk 10 on the tray 5 and clamp it.

Note that the clamping is performed by a magnet (not shown) provided in the pressing member 44 being attracted to the turntable 40. At this time, if the disk 10 is placed obliquely on the suppression member 44 as shown in FIG.
As the disk 10 approaches the disk supporting surface of the turntable 40, the disk 10 moves toward the turntable 40.
The low friction member 78 is in contact with the low friction member 78 . This causes disk 10
is smoothly guided in the radial direction, its inclination is corrected, and it is centered with respect to the turntable 40 with high precision.

In this state, the motor 26 is stopped and the disc can be played.

Thereafter, the turntable 40 is rotated, the carriage 62 carrying the optical pickup is moved, and disk performance is started. Note that after the suppressing member 44 clamps the disk 10 to the turntable 40 by the attraction force of the magnet, the supporting member 45 that supports the pressing member is attached to the suppressing member and the support member in order to make the suppressing member rotatable. It is movable within the gap provided between the members. When a disc is played, the height of the optical pickup is adjusted by driving the support member 45 within this movable range according to the surface runout of the disc 10.

At the same time, the tilt chassis 61 is appropriately driven by the driving means to maintain an orthogonal relationship between the recording surface of the disk 10 and the optical axis of the irradiation light emitted from the optical pickup toward the recording surface.

When a detection means (not shown) detects that the carriage 62 has reached its movement limit position after the disc performance has ended, the carriage 62 and turntable 40 are stopped, and then the motor 26 starts to reverse. Accordingly, as described above, the tray 5 protrudes out of the player housing 2 together with the guide rails 13, 14 by following the process reverse to that described above, resulting in the position shown in FIG. Thereafter, the disk 10 is collected, and the same operation is performed for the disk 8 or the like.

Effects of the Invention As detailed above, in the autoloading disc player according to the present invention, the disc can be protruded from the player housing in a direction parallel to the disc carrying surface of the turntable, and can be freely stored and carried, and transported to the vicinity of the turntable. a drive means for moving the tray, and a disk clamp mechanism for separating a disk that has reached the vicinity of the turntable from the tray and pressing it against the disk supporting surface of the turntable, A low friction member (78) is provided so as to be able to move in and out.

Therefore, as the disk is brought closer to the disk supporting surface of the turntable by the disk clamp mechanism, the disk is smoothly guided in the radial direction by this low-friction member, and the inclination of the disk is corrected. This allows for highly accurate centering.
