DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a disk player which transports a disk by a disk loading device and stably holds a turntable on which the disk is mounted on a motor shaft.

[0002]

2. Description of the Related Art FIG . 6 is a front view showing a disk loading device in a conventional disk player disclosed in, for example, Japanese Utility Model Laid-Open Publication No. 64-846 . In FIG . The loading roller 2, the frame 3, the disk guide 3 fixed to the frame 2 and the loading roller 1, and supporting both ends of the loading roller 1,
Further, the loading arm is rotatably mounted on a support shaft 1 b provided on both side surfaces of the frame 2.

[0003] In the disk transport section, when the disk is transported, an urging force for clamping the disk 5 between the loading roller 1 and the disk guide 3 is applied to the loading arm 4 as a support member. FIG.
Is a plan view of the vicinity of the frame 2. FIG.

Next, the operation will be described. Now, when the disk 5 is inserted in the direction of arrow P in the figure, the disk 5
Is held between the loading roller 1 and the disc guide 3. Further, as the loading roller 1 rotates, the disk 5 is conveyed in the direction of the arrow P in the frame 2.

In this case, the loading roller 1
In addition, tapered portions 1a and 3a are formed on each contact surface of the disk guide 3 with the disk 5 so as to form a gap toward the center of the loading roller 1 in the longitudinal direction. The loading roller 1 and the disc guide 3 come into contact with the outer peripheral end.

[0006]

Since the conventional disk loading device is constructed as described above, it is necessary that the loading roller 1 and the disk guide 3 are arranged in parallel when the disk is transported. When the positional relationship changes, for example, as shown in FIG. 8 , only one end of the disk 5 can be pinched by the loading roller 1, and a gap A may be generated between the loading roller 1 and the disk 5 at the other end. In this case, there is a problem that the carrying force of the disk 5 becomes unstable, and in the worst case, the carrying of the disk 5 becomes impossible.

SUMMARY OF THE INVENTION The first aspect of the present invention has been made to solve the above problems, and provides a disk player capable of realizing a stable disk transport regardless of the degree of parallelism between a loading roller and a disk guide. The purpose is to:

[0008]

According to a first aspect of the present invention, there is provided a disc player including a loading roller having a tapered portion having a diameter decreasing toward a center in a longitudinal direction, and being disposed opposite to the loading roller. A disc guide for guiding the disc sandwiched between the disc and the loading roller to the turntable side, and the disc guide is rotated or bent by a shaft in a direction perpendicular to the disc conveying direction. It is like that.

[0009]

The disc player according to the first aspect of the present invention
Since the disc guide is rotatable or flexibly deformable at a shaft in a direction perpendicular to the disc transport direction, the disc guide is rotated so as to be parallel to the loading roller during the transport of the disc, and thus the disc is evenly displaced. It can be transported while being held by pressure.

[0010]

[Embodiment 1] Hereinafter, an embodiment of the present invention will be described. In FIG.
1 is a loading roller, 2 is a frame, 4 is a loading arm as a support member, and 5 is a disk, and these are the same as those shown in FIGS .
Here, the loading roller 1 is connected to a loading gear 7 to which a rotational force from a driving source (not shown) is transmitted.
It is fixed as shown in FIG.

The loading arm 4 supports both ends of the loading roller 1 and is rotatably mounted on a support shaft 2a provided on both side surfaces of the frame 2. The pins 4a and 4b provided on both side surfaces of the loading arm 4 are respectively provided with press-contact springs 8a and 8b for applying a biasing force in the direction of the disk guide 6 arranged opposite to the loading roller 1 when the disk is transported. Each is attached as shown in FIG.

Further, the disk guide 6 has projections 6b as shafts at its front end (disc insertion port side) and rear end corresponding to the longitudinal center portion of the loading roller 1, and these projections 6b The disk guide 6 is rotatable around the support shaft hole 2b.

Next, the operation will be described. The disk 5 inserted into the disk loading device is sandwiched between the loading roller 1 and the disk guide 6, conveyed by the rotation of the loading roller 1 in the direction of the arrow P in FIG.

In this embodiment, the contact surfaces of the loading roller 1 and the disk 5 of the disk guide 6 are
The loading roller 1 has tapered portions 1a and 6a so as to form a gap toward the center in the longitudinal direction of the loading roller 1, and the loading roller 1 and the disk guide 6 always contact the outer peripheral end of the disk 5 when the disk is transported. It has become.

Further, as shown in FIG. 4, for example, even when the right end of the loading roller 1 is located below the left end, the disc guide 6 can be supported by the shaft hole 2b of the frame 2.
, The disk 5 is held at a position where the right and left ends of the disk 5 are pressed against each other with an equal force.

Similarly, when the left end of the loading roller 1 is located below the right end, the disc guide 6 rotates counterclockwise in the figure around the shaft hole 2b of the frame 2. The left and right ends of the disk 5 are held at positions where they are pressed against each other with an equal force.

Embodiment 2 FIG. In the above embodiment, the rotation axis of the disk guide 6 is the shaft hole 2b provided in the frame 2. However, as shown in FIG. A node 10a may be provided as a shaft, and the node 10a may be bent and rotated by utilizing the elasticity of the disk guide 7, and the same effect as in the above-described embodiment can be obtained.

[0018]

As described above, according to the first aspect of the present invention,
A loading roller having a tapered portion whose diameter becomes smaller toward the center in the longitudinal direction; and a disk guide which is disposed to face the loading roller and guides a disk held between the loading roller and the turntable to the turntable side. In addition, since the disc guide is configured to rotate or bend and deform at the shaft in a direction perpendicular to the disc transport direction, regardless of the height of the loading roller, Both ends of the disc can be reliably held between the disc guide and the disc guide, thereby providing an effect of achieving stable disc transport.
