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 pressing 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 pin 47a, and a disk-shaped cam member 51 is rotated on this support shaft 50. It can be installed freely. As is particularly clear from FIG. 11, the cam member 51 has a spiral cam portion 51a formed around its rotation center axis, and a round pin 47e protruding from the force point portion of the lever member 47 is attached to the spiral cam portion 51a. It can smoothly slide into contact with the shaped cam portion 51a. A gear 51b is integrally formed on the cam member 51, and this gear meshes with the inner rack portion 14b of the right guide rail 14 via two other gears 52 and 53. 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 canceling the DIX lamp, follow this process in reverse. Note that during clamping and unclamping, the lever member 47 rotates while pressing the pressing member 44 against the support member 45 in opposition to the urging force of the spring member 46 (shown in FIG. 8). 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 Figures 2, 8 to 10,
At the rear end of the sub-chassis 41, there is a rectangular first opening 41 through which a protrusion 45a that protrudes upward from the rear end of a support member 45, which is a rotating member, is inserted.
a (shown in FIG. 10) is formed. A circular second opening 45b is formed in this protrusion 45a. The second opening 45b is located above the first opening 41a and has a diameter larger than the width b (shown in FIG. 10) of the first opening 41a. A spherical member 56 having a diameter larger than the width b of the first opening 41a is arranged within the second opening 45b. A receiving plate 57 is fixed to the lower end of the protrusion 45a, and between the receiving plate 57 and the sub chassis 41, the supporting member 45 is attached to the supporting member 45 in a direction approaching the spherical member 56. A coil spring 58 is provided as a biasing means. In addition, the first opening 41a
A circular opening 41b having an inner diameter larger than the width b of the first opening and smaller than the diameter of the spherical member 56 is formed in the center thereof. The spherical member 56 engages with this circular opening 41b, thereby causing the spherical member 56 to engage with the first opening 41a and the second opening 45.
It is positioned so as not to shift relative to b.

That is, a spherical member 56 that is interposed between the support member 45 and the sub-chassis 41 and smoothly slides on the support member 45 and the sub-chassis is positioned within the rotation plane of the support member 45 and perpendicular thereto by the circular opening 41b serving as a positioning means. The support member 45, the sub-chassis 41, and the spherical member 56 are pressed against each other by the coil spring 58, so that the gap between the three members is adjusted to the rotating surface of the support member 45. It is set to zero within the range. With this configuration, the support member 45 rotates with high precision without rattling.

As shown in FIGS. 2, 8, and 9, a tilt chassis 61 is provided on the lower surface of the support member 45 described above.
is rotatably attached via a pin 61b. Note that the pin 61b extends in the left-right direction (the direction of arrow X 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 disk 10 mounted on the turntable 40 and clamped. . Further, although not shown, 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 supporting the tilting chassis 61 has a motor 6 for rotating the tilting chassis 61.

A worm wheel 66 is provided which meshes with the worm wheel 5a, and a pin 66a protruding from the worm wheel radially offset from its rotation center is in smooth sliding contact with one free end of the tilt chassis 61. Further, a spring member 67 is provided that applies a bias force to the tilt chassis 61. Therefore, as the motor 65 rotates and the bias force applied by the spring member 67 causes the tilt chassis 61 to rotate and perform tilt servo.

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 receiving member 76 made of rubber or the like is attached to the disk supporting surface of the turntable 40. As shown in FIG. Further, 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 apply a bias force to the low-friction member are arranged in the circumferential direction of the disk-supporting surface. They are arranged at equal pitches. This low friction member 7
Reference numeral 8 refers to a disk clamping mechanism including a pressing member 44, which abuts against the disk surface as the disk 10, which is mounted on the disk supporting surface of the turntable 40, approaches the disk supporting surface. When the disk 10 is placed on the pressing member 44 in an inclined state as shown in FIG. come into contact with 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 disk is clamped and the disk is centered with respect to the turntable 40 with high precision.

Next, the operation of the autoloading disk 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 out of the player housing 2, and a disk 10, for example, is placed on the tray. Note that the operation of projecting the tray 5 out of the player housing is performed by following the reverse process of the storage operation described below, and 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 disc 10 on the tray 5, when a command to start playing the disc is issued by operating the switch group 7, 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 FIGS. 4a and 4c) provided on the right guide rail 14 engages the swing plate 34 (see FIG. 2). (shown in the figure) to cause the swing plate 34 to swing upward. As a result, as shown in FIG. 7, the clutch portions 19c and 19d of the gears 19a and 19b are disengaged, and the tray 5 stops. From then on, only the gear 19b rotates as the motor 26 rotates, and the guide rail 14 Only backward movement is performed. However, when the tray 5 stops, the left guide rail 13 is not driven and stops. By moving only the guide rail 14 backward, the helical cam portion 51a of the cam member 51 shown in FIG.

0 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 stops and disc performance becomes possible.

Thereafter, the turntable 40 is rotated, the carriage 62 carrying the optical pickup is moved, and disk performance is started. Note that after the pressing member 44 has clamped the disk 10 to the turntable 40 by the attraction force of its magnet, the supporting member 45 that supports the pressing member is
In order to make the pressing member rotatable, it is movable within a gap provided between the pressing member and the support member. Disk 10 when playing disk
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 optical pickup. At the same time, the tilt chassis 61 is appropriately driven by the drive 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 travel limit position after the disc performance has ended, the carriage 62 and the turntable 40 are stopped, and then the motor 26 starts its reverse operation. Therefore, as described above, the tray 5 protrudes out of the player housing 2 together with the guide rails 13 and 14 by following the process reverse to that described above, resulting in the state shown in FIG. 1. After that, collect disk 10, and from now on, disk 8 or 9
Perform the same operation for .

Effects of the Invention As detailed above, the autoloading disc player according to the present invention includes a tray that protrudes from the player housing and is freely retractable and carries a disc and transports it to a playing position, and a tray that carries a disc and transports it to a playing position. It has a rack provided therein, and a driving force applying means that includes a gear meshing with the rack and applies a driving force to the rack, and the deepest portions 16a and 17a of the rack in the storage direction of the tray are the remaining portions. Parts are bendable.

Therefore, when the tray is projected out of the player housing by a predetermined distance in order to attach and detach the disk to the tray, the portions that remain inside the player housing and mesh with the gears are defined as the deepest portions 16a and 17a, The depth of the player can be reduced by bending the deepest portion, for example, at right angles to the tray storage direction as the tray is stored.

Further, in the autoloading disk player according to the present invention, the deepest portion is pivoted to the remaining portion between the rack portion and the non-rack portion, and the deepest portion is attached in the bending direction. the deepest part is in a straight line position with respect to the remaining part by pushing it into contact with the stopper, the non-easy part is made flexible, and in the position where the non-easy part has rotated beyond the stopper. The deepest portion can be separated from the remaining portion.

The position where the non-slip portion exceeds the stopper is the position taken when the deepest portion is attached to and removed from the tray. That is, when removing the deepest part from the tray, bend the non-easy part with your fingers so that the non-easy part does not engage with the stopper, and rotate the deepest part to a position beyond the stopper. , the deepest part is removed from the rest at this position. Moreover, when attaching the deepest part to the tray, this operation is reversed.
Due to this configuration, when attaching the deepest portion to the tray, the effort of handling a retaining nut and the like is reduced, the attachment can be carried out quickly, and the ease of assembly is improved.
