Abutment member 4 for positioning the outer peripheries of the CD and SCD in the insertion path of the disc (CD, SCD) when being drawn into
5 and 46 are provided, and projections 44a and 44b are provided in the vicinity of the contact member 45 so as to protrude to both sides according to the diameter of the SCD. Thus, in the conventional disc reproducing apparatus, for example, when an SCD is inserted, the disc is directly hit against the contact member 45 and positioned without contacting the projections 44a and 44b. On the other hand, when a CD is inserted, the protrusions 44a, 4a
4b, the pull-in direction is guided downward, and abuts against the contact member 46 without contacting the contact member 45 and is positioned. As described above, in the conventional disc reproducing apparatus, the discrimination between the SCD and the CD is formed by a simple structure provided with the projections 44a and 44b so that the disc is slid up and down in the housing 40 and can be reliably positioned. Was.

However, such a conventional disk reproducing apparatus has a structure in which an SCD and a CD are identified and slid up and down in a housing 40, respectively, and the height h of the housing 40 shown in FIG. It was difficult to reduce the thickness. Therefore, in order to solve such a problem, a contact member protruding from the outer periphery of a stopper member formed in the shape of a bar is provided and rotated, so that the contact member is caused to protrude and retract in an insertion path of a disc for identification. Another embodiment of the disc reproducing apparatus has been developed. This prior art is disclosed, for example, in Japanese Patent Application Laid-Open No. 5-151677.
FIG. 10 is a plan view showing another embodiment of such a conventional disc identification structure. Also, FIG.
FIG. 13 is an exploded perspective view showing a mechanism of a contact member 80d for positioning the disk shown in FIG. FIG. 12 is a perspective view showing an engaged state between the switching lever 83 and the lever 81 shown in FIG. FIG. 13 is an exploded perspective view showing a mounting state of the rack member 63 and the arm member 72 shown in FIG. FIG. 14 is a side view showing a state viewed from the direction of arrow D shown in FIG. Further, FIG.
FIG. 7 is a diagram illustrating a state in which the switching lever 83 and the lever 81 illustrated in FIG. 2 are ejected from the disk. FIG. 16 shows the switching lever 83 and the lever 8 shown in FIG. 15 when the SCD is inserted.
FIG. 3 is a diagram showing an operation with No. 1. FIG. 17 shows the switching lever 83 and the lever 81 shown in FIG. 15 when a CD is inserted.
FIG. As shown in FIG. 10, in another embodiment of the conventional disc identification structure, a drive chassis 53 includes three dampers 52 for vibration isolation inside a housing 50 having an exterior formed with an insertion port 50c. Attached through. In the drive chassis 53, a turntable 56 for rotating and driving the disks (CD and SCD) is disposed substantially at the center upper surface, and an optical pickup 54 mounted on the turntable 56 and reading the recorded data of the disk is disposed on a side of the turntable 56. Have been.

[0005] In this case, a disk (SC
(D or CD) is inserted from the direction of arrow E shown in FIG. 10, and a stopper member 80 for positioning the small-diameter disk (SCD) is provided. As shown in FIG. 11, the stopper members 80 are rotatably mounted by inserting shaft portions 80a, 80e between the bent portions 50a, 50a provided in the housing 50. The contact members 80d, 80d are formed so as to protrude and retract by rotating about the axis. At this time, the contact member 80d is
The state shown in FIG. 3 is a state in which the abutment is on the SCD, and the state shown in FIG. Normally, when the disc is ejected, the abutting member 80 d
The lock member 74 has been rotated to the state shown in FIG.
(See FIG. 13). A lever 81 for transmitting a driving force is attached to the stopper member 80, and as shown in FIG. 12, is connected to a switching lever 83 via a torsion spring 82 formed by a reversing spring. Therefore, the stopper member 80
Is formed such that when the switching lever 83 operates in the E or F direction shown in FIG. 12, the lever 81 rotates and is driven simultaneously.

[0006] The contact pin 81a of the lever 81 is shown in FIG.
When the contact member 80d shown in FIG. 1 is rotated to the state shown by (g), it is in contact with one end 85a of the swing member 85. The swing member 85 is rotatably supported by pivotally supporting a shaft 85b on the side plate 50b (see FIG. 10). A spring 89 is attached to the other end 85c of the swing member 85.
, And the other end of the spring 89 is attached to a side plate 50b of the housing 50 (see FIG. 10). The swing member 85 is provided with the spring 89
As shown in FIG. 12 and FIG. 14, the inclined posture is maintained in a neutral posture.

FIGS. 10 and 13 show a housing 50.
As shown in FIG. 5, a rack member 63 is attached to the side of the optical pickup 54, and a gear mechanism 66 composed of two idle gears 64 and 65 for transmitting a driving force is arranged on the side of the rack member 63. A motor 69 (see FIG. 10) that applies a rotational force to the idle gear 64 on the input side of the gear mechanism 66 is arranged in a constant mesh state. And
When the motor 69 is driven, it is transmitted to the rack member 63 via the gear mechanism 66 and the movable portion 63b is fixed to the fixed portion 63a.
Can be relatively moved in the G or H direction. Accordingly, the optical pickup 54 moves along the lower surface of the disk (CD or SCD) within a certain range (within the ranges (d) and (e) shown in FIG. 10). As shown in FIG. 13, the rack member 63 faces a part of the arm member 72 on which the pin member 68 is rotatably arranged. The arm member 72 is further engaged with a lock member 74. Therefore, the motor 69 (FIG. 10)
When the rack member 63 operates by driving the lock member 74, the lock member 74 rotates via the arm member 72.

The switching lever 83 is driven in the E or F direction by a motor M provided on the bottom of the housing 50, as shown in FIG. This motor M has a worm gear 9
0, the power is transmitted to the power transmission mechanism 92 provided on the side plate 50b (see FIG. 10) of the housing 50 at a predetermined timing, and transmitted to the switching lever 83, whereby the switching lever 83 is set to E or F. Drive in the direction.

When discs are identified by another embodiment of the conventional disc reproducing apparatus having such a configuration, first, a user grips a disc (CD or SCD) and inserts the disc into the insertion slot 50c. At this time, in the housing 50, the switching lever 83 is moving in the direction E as shown in FIG. 15, and the contact member 80d is turned to the state of (
The lock member 74 is locked (fixed) by being hooked on the notch 74d of the lock member 74 shown in FIG. When a disc is inserted into the insertion slot 50c, the insertion state is detected by an optical sensor (not shown) arranged near the insertion slot 50c. At this time, if the detected disk is an SCD, the motor M shown in FIG. 14 is driven to slide the switching lever 83 located in the direction E in the direction F as shown in FIG. Thus, the biasing force is applied to the lever 81 in the f3 direction by the reversal of the torsion spring 82 shown in FIG.
4 and is fixed in the state shown in FIG. Then, as shown in FIG. 10, the SCD abuts on the abutment member 80d in the housing 50 and is positioned with its outer periphery regulated.

On the other hand, when the disc detected by the optical sensor is a CD, the motor 69 shown in FIG. 10 is driven together with the motor M (see FIG. 14). When the motor 69 is driven, as shown in FIG. 13, the driving force is transmitted to the rack member 63 via the gear mechanism 66, and further transmitted from the rack member 63 to the arm member 72. The arm member 72 transmits the driving force to the lock member 74 so that the lock member 74 rotates to release the locked state of the contact member 80d hooked on the notch 74d. At the same time, the motor M shown in FIG.
When 3 is slid in the F direction, a biasing force is applied in the f3 direction due to the reversal of the torsion spring 82 shown in FIG. 16, and the lever 81 rotates as shown in FIG.
As a result, the CD inserted into the housing 50 is conveyed into the housing 50 as shown in FIG. 10, and is regulated and positioned by the pin member 50a in a state where the center hole is substantially aligned with the center of the turntable 56. Is done.

Here, although not shown, the switching lever 83 not only controls the attitude of the stopper member 80 via the swinging member 85 but also performs other drive controls at the same time. For example, at the time of reproducing a disk, the drive chassis 53 is supported by a damper or the like so that vibration of the vehicle body does not affect the operation of reproducing the disk. When loading or unloading a disk, the drive chassis 53 is locked inside the housing 50. That is,
While the switching lever 83 moves from the disc playback state to the E direction, the lock mechanism operates to lock the disc drive unit in the housing 50 and place the disc drive unit in the loaded or ejected state,
Conversely, while the switching lever 83 moves in the F direction, the clamper (not shown) separates from the turntable 56 to release the clamp of the disk and place the disk in the loading state.

As described above, the conventional disk reproducing apparatus has:
By rotating the stopper member 80 shown in FIG.
By forming a structure for discriminating D, the arrangement space in the housing 50 is minimized, and the thickness is reduced as compared with the disk reproducing apparatus shown in FIG.

[0013]

However, in the conventional disk reproducing apparatus, as shown in FIG. 11, the arrangement space in the housing 50 is kept to a minimum by using the stopper member 80, thereby realizing the thinning. In this case, since the components such as the conversion lever 83, the lever 81, and the locking member 74 shown in FIGS. 12 and 13 for rotating the stopper member 80 are arranged and operated in the housing 50, the internal structure becomes complicated. As a result, there is a problem that the arrangement space in the housing 50 is reduced and the size is increased. In addition, in the conventional disk reproducing apparatus, when a disk is inserted into the housing 50, the insertion state is detected by an identification unit using an optical sensor in order to identify whether the disk is a small-diameter disk or a large-diameter disk. However, the cost of the optical sensor itself is high, the cost of parts increases, and the cost of the entire device increases. SUMMARY OF THE INVENTION It is an object of the present invention to provide a low-cost disk reproducing apparatus which can solve such problems and can identify and position small-diameter and large-diameter disks with a simple structure and can reduce the thickness of the entire apparatus.

Are urged to slide inward by an urging member such as a spring (not shown). In addition, a stopper member 10 and a trigger slider 20 that are driven based on the detection result of the identification unit 30 are arranged in the housing 1.

The stopper member 10 extends in a rod shape in the housing 1 and is rotatably supported by a rib 1c formed in the housing 1. Further, the stopper member 10 is provided with an abutting member 10a so as to protrude to the outer periphery extending in a rod shape,
By rotating while being supported by the rib 1c, the contact member 1 is rotated.
0a is formed so as to protrude and retract in the disc insertion path. The stopper member 10 is formed in a crank shape by bending both ends of a rod shape at substantially right angles and projecting to both sides again, and is engaged with both ends of the trigger slider 20. Is installed. The switching lever 12 is formed in a substantially L-shape, and has one end connected to a drive source (not shown) such as a motor driven in accordance with the detection result of the identification unit 30.
