[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a disk drive provided with a rotating body for transporting a disk, and more particularly to a disk drive capable of retracting a rotating body in a transport direction.

[0002]

2. Description of the Related Art Disk devices such as CDs and DVDs include:
A transport device having a rotating body for feeding a disk into or out of the apparatus is provided. When the disk is transported, the disk is transported in the front-rear direction of the apparatus by the rotating body rotating in contact with the disk surface.

FIG. 12 is a perspective view showing a transfer device provided in a conventional disk device. This transfer device has a chassis 70, and a roller bracket 71 is supported by the chassis 70 so as to be rotatable around shafts 72, 72. A roller 73 is rotatably supported by the roller bracket 71 about a rotation shaft 74 as a fulcrum. Power transmission means 75 for rotating the roller 73 is provided at one end of the rotation shaft 74. This power transmission means 75
It is composed of a motor M and a gear group.

The above-described transport device can be mounted on various disk devices. In particular, in a vehicle-mounted electronic device, in addition to the disk device, for example, a TV or a navigation system is provided by combining functions in recent years. Incorporating a liquid crystal display panel and an amplifier for use as an integral part.

However, the size of the case of an in-vehicle electronic device is determined by a standard, so that, for example, when a liquid crystal display panel is incorporated, it is necessary to reduce the size of other disk devices. Therefore, the conventional transporting device requires extra space for rotating the roller 73 in the vertical direction, so that a large amount of space in the vertical direction is required. It becomes very difficult to incorporate. Further, when an amplifier and the like are provided integrally, the space in the depth direction of the disk device is limited.

As described above, in the transfer device provided with the roller bracket 71, since the rollers 73 are moved in the vertical direction, it is difficult to reduce the thickness of the disk device.

Further, in the conventional transfer device, the contact state between the roller and the disk D is not uniform due to the roller mounting error, the unevenness of the roller surface, and the distortion of the disk, and the disk D cannot be transported smoothly. There were also problems.

The present invention solves the above-mentioned conventional problems. In particular, a mechanism having a low height allows a rotating body to be retracted from a disk, thereby making it possible to reduce the thickness and size of the apparatus. It is an object to provide a disk device.

Another object of the present invention is to provide a disk device capable of reliably transporting a disk by reliably bringing a rotating body into contact with the disk.

According to a first aspect of the present invention, there is provided a disk apparatus provided with a rotating member for sending a disk into and out of a case and a power source for rotating the rotating member. The body is bendable or bendable, and moves the rotating body away from the outer periphery of the disk and away from the disk surface of the disk with respect to the disk loaded and installed in the case by the rotating body. A deformation applying means for deforming in at least one of the directions is provided.

In the first aspect of the present invention, since the rotating body is retracted away from the disk by deforming the rotating body, the rotating body can be separated from the loaded disk by a simple and thin mechanism. it can.

It is characterized by being provided with a deformation applying means which can be bent and deforms the rotating body in a direction contacting the disk when transferring the disk.

In the second aspect of the present invention, since the rotating body is deformed and pressed against the disk to apply a transfer force to the disk from the rotating body, there is no slippage between the rotating body and the disk, and the disk is securely held by the rotating body. Can be transferred to

For example, both sides of the rotating body are supported by a support, and the deformation applying means applies a force to the side of the rotating body inside or outside the support, so that the support is supported by the support. Is used as a fulcrum to apply a deforming force to the support and the rotating body in the intermediate portion between the supports.

As described above, since the rotating body can be deformed only by applying a force to the side of the rotating body, a large movement in the thickness direction of the disk is not required for the deformation applying means. Therefore, the thickness can be reduced.

For example, the deformation applying means may be configured to have a slide body which moves in a direction intersecting the axis of the rotating body inside or outside the support and applies a force to a side portion of the rotating body. .

Here, the slide body is provided with a guide path along the direction in which the disk is transported, and when the slide body moves, a force is applied to one end of the rotary body by one end of the guide path. The rotating body may be deformed in a direction away from the outer periphery of the disk.

Further, the guide path is provided with a guide portion which presses a side portion of the rotating body to deform the rotating body so as to come into contact with the disk when the sliding body is moved. Is possible.

Further, an arm is provided at each of both ends of the rotating body, and the deformation applying means applies a turning force in opposite directions to the both arms to apply a deforming force to the rotating body. It is also possible to use

In this case, it is possible to have a slide body which moves in the axial direction of the rotating body, and the slide body is provided with a guide path for applying the turning power to the arm. .

The rotating body may be configured to have a shaft that can be bent or bent and a rubber or resin roller that covers the shaft and that is elastically deformable.

The edge of the disk D is guided by b and 3b. The guide member 3 has a shape in which substantially the entire lower surface is open, and when the disk D is set in the guide member 3, substantially the entire recording surface on the lower surface of the disk D is exposed.

The chassis 1 is provided below the guide member 3 with a rotary drive means 25 for driving the disk D to rotate. The rotation drive means 25 has a turntable T, on which the rotation center S of the disk D is mounted.

Outside the side plates 1a, 1a of the chassis 1, slide plates (slide bodies) 6, 6 functioning as deformation applying means are provided. The slide plates 6 and 6 are formed of a metal plate, are formed rearward from the front end of the chassis 1, and are connected to each other by a connection plate 7. The driving force of a motor (not shown) is converted to linear motion by the connecting plate 7 and is moved integrally along the front-back direction (transport direction) of the disk D.

On the side surfaces of the slide plates 6, 6, one guide path 6a, 6a is formed in the front-rear direction. The guide paths 6a, 6a have a guide hole (guide portion) 6a1 and a guide hole (guide portion) 6a2 having different vertical heights at the front and rear. The front end 6b of the guide hole 6a1 is

A power transmission means 11 is provided between the one side plate 1a and the slide plate 6 for applying a rotating power to the rotating body 2. The power transmission means 11 includes a motor M as a power source and a gear group G.

As shown in FIG. 1 and FIG. 4, the power transmission means 11 has a gear 8 fixed to a shaft 5 and a gear 8 and a shaft 5.
And rotate together. Idle gear G
2 meshes with the main gear G1. In FIG. 4, a gear group provided between the main gear G1 and the motor M is not shown, but a reduction gear group is provided as appropriate.

As shown in FIG. 4, a connecting arm 12 is rotatably supported on the shaft of the main gear G1, and an idle gear G2 is rotatably supported on the connecting arm 12. Therefore, in a state where the idle gear G2 and the main gear G1 always mesh with each other, the rotation center C2 of the idle gear G2 is
1 can go around. One end of a biasing member 13 such as a coil spring is fixed to the connecting arm 12, and the other end is fixed to the chassis 1 or the like. As a result, the connection gear 12 is constantly urged upward, so that the idle gear G2 is pressed against the gear 8 and always meshes.

In the power transmission means 11, a gap formed when the rotation center (shaft 5) of the gear 8 and the rotation center C1 of the main gear G1 are connected in a straight line, that is, the gear 8 is separated from the main gear G1 by a maximum. Is within a range not exceeding the pitch circle diameter of the idle gear G2.
And the gear 8 always mesh with each other.

Next, the operation of the transfer device 10 which is a feature of the present invention will be described. When the disc is not inserted, the slide plates 6, 6 are moved rearward, and the shafts 5, 5 are located in the guide holes 6a1, 6a1. The height positions of the guide holes 6a1, 6a1 coincide with the heights of the shaft holes 4a, 4a of the bearing members 4, 4. Therefore, no vertical external force acts on the shaft 5. Further, other rollers or sliding pads are provided above the rotating body 2, but between the rotating body 2 that is not bent and deformed as in the state of FIG. 1 and the other rollers or sliding pads. Has a gap with a height greater than the thickness of the disk.

When the disk D is inserted by hand from the opening of the disk device on which the transfer device 10 is mounted, this is detected by the detection means, and the power transmission means 11 starts to rotate the rotating body 2. At the same time, the slide plates 6 and 6 start to move forward at the same time.

When the slide plates 6 and 6 move forward in FIG. 1, the shafts 5 and 5 are guided into the guide holes 6a2, and the tips of the shafts 5 and 5 are pushed downward by the guide holes 6a2. . Therefore, the shafts 5 and 5 have shaft holes 4a and 4
a bending force with the fulcrum as a fulcrum, and the side plates 1a and 1a
Is rotated and deformed so that its axial center portion is lifted upward. At this time, a slight movement of the bearing members 4, 4 in the grooves 1a1, 1a1 of the side plates 1a, 1a allows the shafts 5, 5 to tilt. When the rotating body 2 between the bearing members 4 and 4 is bent upward, the disk is sandwiched between the central portion of the rotating body 2 and the other roller or the sliding pad.

In the power transmission means 11 shown in FIG. 4, the main gear G1 is rotated by the driving force of the motor M, and the main gear G1 is rotated.
Rotates the idle gear G2. And
The torque of the idle gear G2 is transmitted to the gear 8, and the gear 8
At the same time, the shafts 5, 5 and the rotating body 2 rotate. When the shafts 5 and 5 are pushed down by the guide holes 6a2 as described above, the gear 8 fixed to the shaft 5 also becomes D1 in FIG.
Slightly pushed down in the direction. However, at this time, the transmission of the power to the gear 8 was interrupted because the idle gear G2 circulates the main gear G1 clockwise and descends slightly, and the idle gear G2 is pressed against the gear 8 by the urging member 13. Never be.

As described above, in the transfer device 10, as shown in FIG. 3, before the power transmission means 11 starts, a minute gap is formed between the disk D and the rotating body 2 (broken line). When the power transmission means 11 is started, the center of the rotating body 2 (solid line) is deformed to be lifted upward, and the rotating body 2 reliably contacts the lower surface of the disk D. Then, the disk is transferred inward by the rotational force of the rotating body 2.

The rotation center S of the disk D is
Disk D until it is transported to the turntable T
Is in contact with the rotating body 2.

When the rotation center S of the disk D coincides with the turntable T and the rotation center S is clamped on the turntable T, the slide plates 6 and 6 are moved backward. When the shafts 5 and 5 are guided to the guide holes 6a1 and 6a1 of the slide plates 6 and 6, the shafts 5 and 5 are guided.
Is released, the bending deformation of the rotating body 2 is released, and the rotating body 2 has a shape extending linearly.
At this time, the rotating body 2 separates from the disk. Therefore, when the turntable T is rotated in this state to rotate the disk, the disk is rotated without contacting the rotating body 2.

At this time, as shown in FIG. 6, the tips of the shafts 5 and 5 are pushed upward by the guide holes 6a1 and 6a1, and the intermediate portion in the axial direction of the rotating body 2 between the side plates 1a and 1a. It is also possible to bend and deform so as to be convex in the direction away from the disk. When the rotating body 2 is bent downward in this manner, the rotating body 2 can be further separated from the disk being driven for rotation.

In this embodiment, it is also possible to retract the rotating body 2 from the outer periphery of the disk placed on the turntable T. This retreat operation can be performed by moving the slide plates 6 and 6 largely backward.

When the slide plates 6 and 6 move largely rearward, the shafts 5 and 5 are pulled rearward by the front ends 6b and 6b of the guide holes 6a1 and 6a1. At this time, the shafts 5 and 5 are
Outside the a and 1a, the rotor 2 is pulled rearward with the shaft holes 4a and 4a as fulcrums, and between the side plates 1a and 1a, the rotating body 2 is bent and deformed so as to be convex forward.

As a result, as shown by a chain line in FIG. 2, the central portion of the rotating body 2 is retracted to a position outside the edge of the disk D, and the vertical overlapping of the rotating body 2 and the disk D is eliminated. You. Therefore, it is possible to move the disk D up and down, for example, by moving the disk up and down in the case to replace the disk to be played, or to move the disk loaded by the rotating body 2 downward. An operation such as mounting on the turntable T while moving is enabled.

When the shafts 5 and 5 are pulled backward, the gear 8 simultaneously moves in the direction B1 shown in FIG. 4. At this time, the idle gear G2 moves in the direction D2 due to the moving force of the gear 8 in the direction B1. It can escape, and no excessive force acts on the power transmission path.

As described above, the rotating body 2 is
By bending the disk D more forward than the case and removing it from the disk, the disk D can be rotated at a position close to the opening of the disk device, and the depth of the disk device can be reduced, and the size of the disk device can be reduced. It is possible.

Next, a rotating body 20 shown in FIG. 5 is a modified example of the rotating body 2 of the transfer device 10. In the rotating body 20 shown in FIG. 5, a pair of cylindrical rigid bodies 2a, 2a are arranged at predetermined intervals in the axial direction, and the opposing surfaces of the rigid bodies 2a, 2a are made of a metal that can be elastically deformed in the bending direction. They are connected by a wire 2b. The entire body including the outer peripheral surfaces of the rigid bodies 2a and 2a and the wire 2b is covered with a rubber roller 22, but a cut surface is formed at the center of the roller 22 so that the roller is separated into 22a and 22b. .

Also in the transfer apparatus 10 shown in FIG. 5, when the disk D is transferred, the rotating body 20 is held in a linear shape without being deformed and is slightly separated from the disk D, or the rotating body 20 is moved as described above. The disk D is slightly deformed and comes into contact with the disk D. When the disk D is stored in the guide member 3 and the conveyance is completed, the slide plates 6 and 6 are slid backward as described above, so that the center of the rotating body 20 in the axial direction is bent forward. Become. At this time, the rollers 22a and 22b are separated, and the rubber roller 22 of the rotating body 20 is shaped like a letter C, and the rotating body 20 is easily deformed to a position where it does not overlap the disk D in the vertical direction.

In the above embodiment, the rigid bodies 2a, 2a
a and the shafts 5 and 5 are not deformed, and only the wire 2b is elastically deformed. However, one shaft is inserted through the center of the roller, and the entire shaft can be elastically bent. Is also good.
