Abstract

PROBLEM TO BE SOLVED: To surely introduce a disk onto a turntable without providing a disk player with a disk retaining member and guide member. SOLUTION: When a tray T on which the disk D is placed is drawn out, an inclined disk-like clamper 12 is pressed to the front surface of the disk D by the elastic force of a leaf spring 15 and as the tray is drawn out, the clamper 12 rolls on the front surface of the disk D. The slip of the disk D from the tray T is therefore prevented. When the tray is drawn out to a prescribed position, the disk D is grasped and clamped by the turntable 13 and the clamper 12.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a disc player having a clamper for holding a disc with respect to a disc installation section such as a reproducing unit, and more particularly to a disc having a function of a clamper for holding a disc to be fed so as not to move. Regarding the player.

[0002]

2. Description of the Related Art FIG. 4 is a schematic structural view showing an apparatus called a so-called disc changer which is a kind of a conventional on-vehicle disc player.

A disc changer 1 shown in FIG. 1 is a magazine M containing a plurality of trays T on which discs D are placed.
And a reproducing unit U equipped with a mechanism for reproducing information recorded on the disk D.

In the disc changer 1 having the above structure, when the tray T is pulled out from the magazine M, the reproducing unit U rises, and the disc D on the tray T pulled out is transferred to the turntable 3 provided in the reproducing unit U. While being installed and lifted, the clamper 2 descends and the disc D is held between the clamper 2 and the turntable 3. In this state, the disk D is driven to rotate,
Information is reproduced by an optical pickup (not shown).

[0005]

However, in this type of apparatus, the disk D is displaced from the tray T being pulled out due to vibrations or the like transmitted from the vehicle, or the disk D is dropped from the tray T, and the device is turned. There is a case where the disk D is not accurately guided on the table 3.

Therefore, for example, as shown in FIG. 4, it is necessary to provide a pressing member such as a pressing roller 4 for pressing the disk D against the tray T when the tray T is pulled out. Is provided on the tray T, the tray T is pulled out, the disc D is clamped on the turntable 3, and then when the disc D is driven to rotate, the pressing roller 4 is moved from the disc D. It is necessary to separate them, and an evacuation drive mechanism is required, which complicates the device structure.

It is an object of the present invention to provide a disc player which can prevent a displacement of a disc to be fed without providing a mechanism such as the pressing roller.

[0008]

In order to achieve the above-mentioned object, the present invention is constituted by a tray on which a disk is placed and transferred to a reproducing unit by a transfer mechanism, and a disk provided in the reproducing unit and transferred. In a disk player having a turntable to be mounted and a substantially disk-shaped clamper rotatably provided on a clamper support and holding the disk between the turntable and the turntable, the clamper is elastic with respect to the clamper support. It is provided via a member and is supported by the elastic member in a state of being inclined in the direction of the turntable when the disc is not clamped, and when the tray is transferred to the reproducing section, the inclined end of the clamper is used. It is characterized in that the lifting of the disk on the tray is restricted.

Further, when the tray is transferred to the reproducing section, the inclined end of the clamper abuts on the upper surface of the disk on the tray, and the clamper rotates as the tray moves. it can.

[0010]

In the above means, for example, a tray on which a disc is placed is pulled out of a magazine, and when this tray is transferred to the reproducing unit by a transfer mechanism, the inclined end of a substantially disk-shaped clamper supported in an inclined state. The lifting of the disc on the tray is regulated by the section, and the disc is reliably placed on the turntable of the reproducing section and clamped by these.

Further, if the inclined end of the clamper is brought into contact with the upper surface of the disk on the tray and the clamper rolls and presses the disk sent to the reproducing section, the lifting of the disk is more reliably restricted. In addition, it is possible to prevent the upper surface of the disk from being damaged.

[0012]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a front view showing an on-vehicle disk changer according to an embodiment of the present invention, FIG. 2 is a view in the direction of arrow II in FIG. 1, and FIGS. 3 (a) and 3 (b) show the disk changer. It is operation | movement explanatory drawing.

A disc changer 11 shown in FIG. 1 includes a magazine M containing a plurality of trays T on which a disc D is placed, a reproducing unit U having a pickup for reproducing information recorded on the disc D, and the like. It is roughly constituted from.

The reproducing unit U is provided with a turntable 13 for supporting and lifting the disk D on the tray T as the reproducing unit U is lifted when the tray T is pulled out of the magazine M. . A clamp arm 14 is rotatably supported by the reproduction unit U,
The turntable 13 is attached to the clamp arm 14.
Is provided with a clamper 12 for holding the disk D therebetween.

The clamper 12 has a disk shape and is rotatably supported by a tip of a leaf spring 15 fixed to the clamp arm 14. Further, the leaf spring 15 is arranged to be inclined in a direction crossing the drawing direction of the tray T,
Thus, when the disc D is not clamped, the clamper 12 is supported in a state of being inclined in the direction of the turntable 13. The lowermost end (inclined end) E of the clamper 12 in this inclined state.
Is a position corresponding to the moving tray T.
That is, when the tray T is pulled out of the magazine M or stored, the lowermost end E of the clamper 12 is closed.
Rolls on the surface of the disk D on the tray T. Further, when the clamp arm 14 is driven after the disk D is guided onto the turntable 13, the leaf spring 15 is deformed, and the clamper 12 and the turntable 1 are turned.
The rotation centers of the disc D and the disc 3 coincide with each other so that the discs D can be held between them.

The tray T has a recess for accommodating the disc D, and a notch at a position facing the turntable 13. As shown in FIG. 1, a notch 16 for guiding the lowermost end E of the clamper 12 to the surface of the disk D is formed at the tip of the tray T.
Are formed.

Next, the disk changer 11 having the above configuration
Will be described with reference to FIGS. 3 (a) and 3 (b).

When a desired disc D is selected, the reproducing unit U is driven in the Y1 direction or the Y2 direction in the drawing, and stops at a position facing the tray T on which the desired disc D is placed.

At this position, when a desired tray T is pulled out by a tray transfer mechanism (not shown) provided in the reproducing unit U, the lowermost end E of the clamper 12 passes through the notch 16 and Hit the surface of D.
At this time, the clamper 12 presses the disk D in the Y2 direction by the elastic force of the leaf spring 15, and the clamper 12 rolls on the surface of the disk D as the tray T is pulled out.
The lifting force of the disc D from the tray T is regulated by the pressing force of the clamper 12.

When the tray T is pulled out in the above state, the disc D moves while rollingly contacting the lowermost end E of the clamper 12, and the tray T is pulled out to a predetermined position, and the center of the disc D and the turntable are moved. When the center of the disc 13 coincides with the center of the disc 13, the reproducing unit U is slightly raised, and the disc D is set on the turntable 13. Then, the clamp arm 14 descends, and as shown in FIG. 3B, the disk D is clamped between the turntable 13 and the clamper 12.

As described above, according to the disk changer 11, the disk D being transferred is prevented from being displaced from the tray T by using the clamper 12 as a pressing member.

In the conventional disc changer 1 shown in FIG. 4, the gap G between the clamper 2 and the turntable 3 needs to be wide so that the tray T and the disc D to be drawn out do not collide with the clamper 2 and the turntable 3. However, the disc changer 11 has a configuration in which the clamper 12 is brought into contact with the disc D, so that the gap G may be made as small as possible so that the tray T or the like can be moved, which contributes to downsizing of the apparatus. it can.

In the above embodiment, the clamp arm 1
The clamper 12 is urged in the direction of the turntable 13 by a leaf spring 15 provided on the clamp 4.
The rotation shaft of is supported by the clamp arm 14,
The clamper 12 may be urged toward the turntable 13 in an inclined posture by a coil spring or the like. In any case, the clamper 12 is connected to the turntable 13.
If the clamper 12 is supported in an inclined state by an elastic member that urges in the direction of, that is, applies a disc holding force, an increase in the number of parts can be suppressed.

As described above, in the on-vehicle disk changer of this embodiment, the tray T on which the disk D is placed is pulled out of the magazine M, and the tray T is transferred to the reproducing unit U by the tray transfer mechanism. In addition, the lower end E of the clamper 12 supported in an inclined state
The surface of the upper disk D is pressed, and the lifting of the disk D from the tray T is restricted. Therefore, the disc D is securely guided and placed on the turntable 13 of the reproducing unit U.

When the tray T is fed into the reproducing unit U with the lowermost end E of the clamper 12 in contact with the upper surface of the disk D on the tray T, the clamper 12 rolls on the surface of the disk D. Since the disk D is pressed down, there is no possibility that the surface of the disk D will be damaged by sliding contact with the clamper 12 or the like.

[0027]

As described above, according to the present invention, since the clamper functions to press or guide the disk to be fed, the pressing roller 4 shown in FIG. 4 and other pressing mechanisms or disk guide mechanisms are not required. Thus, the device structure of the disc player can be simplified.
