[0002]

2. Description of the Related Art FIG. 7 is a schematic view showing the structure of a conventional holder-movable disk device.
It is the same as that disclosed in Japanese Patent No. 3552 and the like. This disk device is a so-called 1-din (DI
N) size, the housing 1 is installed by being embedded in an instrument panel inside a vehicle compartment. Holder 2
Is to move between the inside and the outside of the housing 1 as indicated by the arrow. FIG. 7 shows a state in which the holder 2 is projected to the outside of the housing 1. However, when the holder 2 moves inward of the housing 1 and is stopped at that position, The magazine M is inserted and loaded into the holder 2 from the right side in the drawing. In the magazine M, a plurality of discs D such as compact discs are used as recording media.
Is stored, and the left end of the magazine M in the drawing is a disc D.
Is the entrance Ma.

A disk drive unit K is provided in the housing 1. The drive unit K includes a drive chassis 3, a rotary body 4 provided on the drive chassis 3, a spindle motor (not shown) for driving the rotary body, and a rotary body 4
Facing the disk D which is rotationally driven by the disk D
And an optical head H for reading the optical signal recorded in. A base end portion of a clamp arm 5 is rotatably supported on the drive chassis 3, and a clamp member 6 is rotatably supported on a tip portion of the clamp arm 5.

On the right side of the drive section K in the figure, there are provided a feed roller 7 and a counter roller 8 which constitute a disk take-out means. When the holder 2 is moving to the position where it overlaps with the clamp member 6 inside the housing 1, the feed roller 7 moves downward and the facing roller 8 moves together with the holder 2.

When pulling out one of the discs D from the magazine M or returning the disc D to the magazine M, as shown in FIG. 7, the holder 2 and the magazine M loaded in the holder 2 are inserted into the casing 1. Outside, that is, to a position that does not hinder the operation of the clamp member 6, and temporarily stops at that position. At this time, the feed roller 7 and the opposing roller 8 approach each other, and both rollers 7 and 8 stop at a position facing the disk D to be selected in the magazine M. Selected disc D
(In FIG. 7, the one located in the middle of the three disks in the magazine M) is fed from the magazine M to the feed roller 7
And the opposing roller 8 are pushed out, and are transported leftward in the drawing by the rotational force of the feed roller 7.

When a disc is selected, the clamp arm 5 is rotated upward as shown in FIG. 7, and the disc D transferred by the feed roller 7 moves between the drive chassis 3 and the clamp arm 5. Next, the clamp arm 5 rotates downward, and the central portion of the disc D is clamped by the clamp member 6.
The disk D is pressed against the rotating body 4 by the
Clamped on. Then, the holder 2 and the magazine M move into the space above the descending clamp arm 5 and clamp member 6, and in that state, the disk D is rotationally driven by the rotating body 4, and the optical signal is transmitted by the optical head H. Read.

When the disc D which has been reproduced is returned to the magazine M, the holder 2 projects to the outside of the housing 1 and the clamp arm 5 rotates upward to rotate the disc D, as shown in FIG. The clamp is released. Then, the disc D is pushed up by the lower feed roller 7, and the feed roller 7
The disc is nipped between the feed roller 7 and the opposing roller 8
The disc D is returned to the magazine M by the feeding force of.

[0008]

In this disc device, as shown in FIG. 7, when the holder 2 projects from the housing 1, the disc D is taken out from the magazine M by the feed roller 7 and the opposing roller 8. Rotating body 4 of drive unit K
When the disc D is completely ejected from the magazine M, the holder 2 starts to move to the left in the figure at the same time when the clamp arm 5 starts to descend. By increasing the speed of this continuous operation, the time required until the disc D in the magazine M is loaded into the drive unit K can be shortened.

Therefore, when the holder 2 starts moving from the state of FIG. 7 to the left in the drawing, the disk immediately after being taken out from the magazine M easily hits the lower edge 2a of the left end of the holder 2 in the drawing, or the disk D is , Holder 2
It was easy to get into the gap (d) between the bottom plate and the magazine M. In particular, when a mechanism for locking or ejecting the magazine M is provided between the bottom of the magazine M and the bottom plate of the holder 2 and there is a large gap in the above-mentioned part (d), the disc D has this gap ( D) It becomes easier to enter inside. If such a phenomenon occurs, the movement of the holder 2 to the left in the drawing is hindered, the mechanism is locked, or the disc is damaged.

In order to prevent this, when the disc D is clamped by the feed roller 7 and the counter roller 8 and the disc D is taken out from the magazine M, the counter roller 8 is moved a long distance downward in the figure, It is conceivable that the opposing roller 8 forcibly presses the disk D downward in the figure to make it difficult for the disk D to hit the holder 2 that moves leftward in the figure. However, this measure not only complicates the mechanism because the operation stroke of the mechanism needs to be large in order to move the opposing roller 8 downward in the figure for a long time, but also the vertical movement stroke of the roller 8 increases. Problems arise such as hindering the thinning of the entire device.

The present invention is to solve the above-mentioned conventional problems. When the holder moves toward the drive unit, the disk taken out from the holder is surely guided to the outside of the holder, It is an object of the present invention to provide a disc device capable of surely preventing the holder or the disc or the magazine from hitting each other, and realizing the above-mentioned measures without complicating the mechanical structure.

The feed roller 61 is supported by a support bracket (not shown), and the support bracket is rotatably supported in the housing 11. The feed roller 61 can be pressed against the opposing roller 62 by an elastic member (not shown), and the feed roller 61 is rotationally driven by the power of the feed motor. The counter roller 62 is supported by the holder 12, and the counter roller 62 moves up and down at the position shown in FIG. 2 by a selection mechanism (not shown), and the feed roller 61 follows this, and the three discs in the magazine M Any one of D is selected.

The operation of the disk device 10 will be described.
As shown in FIG. 4, when the holder 12 is inside the housing 11, the holder 12 stops at the first position in the region above the clamp arm 55 and the clamp member 56 that are descending to the clamp state. ing. At this time, the facing roller 62 is moving together with the holder 12 in the (a) direction. Further, the feed roller 61 supported on the housing 11 side
Are lowered to a position that does not hinder the movement of the holder 12.

As shown in FIG. 4, when the holder 12 is at the first position, the magazine M is inserted into the holder 12 in the (a) direction, and the spring members 13a and 13b cause the magazine M to move with a proper elastic force to the bottom plate. It is pressurized in the direction of 12a. Then, as shown in FIG. 6, the lock pin 46 of the lock / push mechanism 40 enters the lock groove Md on the bottom surface of the magazine M, and the magazine M is locked. Further, when the magazine M is ejected from the holder 12 located in the housing 11, the ejection driving member 32 rotates the actuating member 49, and the pushing pin 43 pushes the magazine M in the (B) direction.

When the disk D is selected and taken out from the magazine M, the disk cam 21 rotates, the drive links 23 and 24 extend in the X state, and the holder 12 (b).
Move in the direction. At the same time, the clamp arm 55 and the clamp member 56 are raised to be in the unclamped state, but when the clamp arm 55 is raised, the holder 12 does not prevent the clamp member 56 from being raised to the unclamped position in the (b) direction. And stop at the second position shown in FIG.

At this time, the feed roller 61 is the opposite roller 6
2 and moves up to a position where the pressure is applied, and by the vertical movement of the feed roller 61, the take-out means constituted by both rollers 61 and 62 moves to a position where one of the disks D in the magazine M is selected. . In FIG. 2, the rollers 61 and 62 forming the take-out means are moved to the position of, and the one stored in the uppermost one of the three disks D in the magazine M is selected. There is. The uppermost disc D has both rollers 61 at the position pushed out in the direction (a) by the pushing mechanism in the magazine M.
The disc D is transported in the direction (a) by the rotational force of the feed roller 61. The tip portion of the disc D, which is transported in the direction (a), in the transport direction is supported by the support wire 57, and the disc D is supported by the support wire 57.
Both ends are supported by both rollers 61 and 62.

Immediately after the removal of the disc D from the magazine M is completed, the rotational force of the disc cam 21 causes the holder 12 to start moving in the (a) direction toward the first position. At this time, the counter roller 62 supported by the holder 12 descends to the position shown in FIG. 2, and following this descends to the position of the feed roller 61 as well. The edge Da on the holder side of the disk D is held between the rollers 61 and 62 at this point. However, as shown in FIG. 3, when the holder 12 slightly moves in the (a) direction, the opposing roller 62 reaches the position where it is raised and the edge Da of the disk D is lowered to the position where the feed roller 61. It will be in the state of riding on. Therefore, as shown in FIG. 3, the edge Da of the unstable disk D supported by the support wire 57 and the feed roller 61 is the end of the holder 12 on the (a) side, the bottom of the magazine M, or It is easy to hit the gap between the holder 12 and the magazine M.

In the illustrated example, the notch 12f of the holder 12
Since the concave portion Mb on the bottom surface of the magazine M appears at the portion of, the holder 12 moves in the direction (a),
The edge Da of the disc D easily enters the magazine because it enters the recess Mb. Alternatively, the push-out member 42 and the lock member 45, which are included in the lock / push-out mechanism 40 and located on the lower surface of the bottom plate 12a of the holder 12, are also easily hit.

However, as shown in FIG. 6, the edge Da of the disk D is notched in the holder 12 and the magazine M.
The edge Da of the disk D contacts the inclined guide portion 15e of the guide member 15 at the time of entering the recess Mb of the bottom surface, or immediately before or immediately after entering the recess Mb. The inclined guide portion 15e approaches the bottom surface of the recess Mb at a distance shorter than the plate thickness of the disk D, and the holder 12
Below the bottom plate 12a, the lock / push mechanism 40 extends to a position lower than the lock member 45 and the like constituting the mechanism 40. Therefore, when the holder 12 further moves in the direction (a) from FIG. 2 to FIG. 3, the edge portion D of the disk D is
a is the bottom plate 12a of the holder 12 due to the inclined guide portion 15e.
And the edge portion Da does not hit any of the portions.

Then, as shown in FIG. 4, the clamp member 5
6 is completely lowered, the supporting wire 57 is also lowered, and when the disk D is clamped by the rotating body 53 and the clamp member 56, the holder 12 and the magazine M are stored in the first position. In this state, the reproducing operation of the disc D is performed.

In the above configuration example, as shown in FIG. 3, when the holder 12 and the magazine M move in the direction (a), even if the opposing roller 62 is raised to the position, the tilt guide portion 15e causes the disc to move. The edge Da of D is the holder 1
It is surely guided to the lower part of 2. Therefore, it is not necessary to lower the facing roller 62 further downward than the position shown in FIG. 2 and press down the edge Da of the disk D in the state shown in FIG. Therefore, the opposing roller 62 may be immediately raised from the position shown in FIG.
The moving stroke of the facing roller 62 can be shortened. Further, it is not necessary to set the timing between the position of the facing roller 62 and the time when the holder 12 starts moving with high precision.
Therefore, the mechanism for moving the facing roller 62 can be simplified, and the vertical stroke of the facing roller 62 is short, so that the device can be made thin.

In the above configuration example, both the lock pin 46, which is a part of the lock member 45, and the push pin 43, which is a part of the push member 42, enter into the recess Mb on the bottom surface of the magazine M. However, only one of the lock member and the pushing member may enter the recess Mb formed in the magazine M.

1 and 5, the bottom plate 12a of the holder 12 is formed with a notch 12f. However, in the case where the notch 12f is not formed, the end portion of the holder 12 on the (a) side is formed. The bottom plate 12a and the recess Mb of the magazine M.
A gap with is formed. Also in this case, by providing the inclined guide portion, it is possible to prevent the disc from entering the gap.

Furthermore, the present invention is not limited to a magazine in which discs are loaded in the holder 12, and a plurality of discs such as mini discs (MD) in which a single disc is stored in a case are holders. The present invention can be carried out even if the discs are individually loaded into the holder and the individual discs are taken out from the holder together with the case. In this case, it is possible to prevent the case from hitting the holder or the like.

[0044]

As described above, according to the present invention, in the case where the holder having the disk inside moves and stops at the position where the holder overlaps with the driving portion, the inclined guide portion is provided in the portion facing the driving portion side of the holder. Therefore, the disc taken out from the holder can be prevented from hitting the holder or the magazine, and the movement operation of the holder can be surely performed. It is also possible to speed up the timing when the holder moves from the second position to the first position to speed up the disc ejecting operation.
