Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an apparatus for carrying in a 120 mm size disk on a turntable in the disk apparatus.
[0002]
[Prior art]
The disk device records and reproduces information while rotating with the disk mounted on the turntable. There are various methods for mounting the disk device on the turntable. The typical method is a method of inserting into the apparatus main body by placing it on a tray that moves forward and backward, and when a part of the disk is inserted from the insertion port, a loading device that is provided inside the apparatus and can be pulled in, There is a method of pulling it to a predetermined position and attaching it to the turntable.
[0003]
The disk device targeted by the present invention is a type of disk carry-in device that is mounted on a turntable by the latter method. This disk device is only provided with a thin insertion slot on the front panel, and a part of the disk is inserted through the insertion slot, so that the disk apparatus is loaded and mounted. Therefore, as a conventional disc carry-in device, a “CD player loading device” according to Japanese Patent Laid-Open No. 2-7263 is known.
[0004]
The “CD player loading device” is arranged on the player main body so as to be opposed to each other at a predetermined distance, and each of the first and second belt mechanisms for loading a disc is rotatable, Belt mechanism opening / closing means for rotating each of the belt mechanisms in a predetermined direction when loading the disk, and at least one of the first and second belt mechanisms removes the belt constituting the belt mechanism as needed. A loading motor that rotates in a predetermined direction is provided.
[0005]
Further, instead of the first belt and the second belt, there is a method in which a plurality of vertical rollers are provided on the left and right of the insertion slot, the disc is sandwiched between these rollers, and the disc is carried in by rotation of the roller. The left and right rollers slide to detect 80mm discs and 120mm discs, and the position of the disc is detected by operating the switch with a lever that connects the shafts of both rollers. Positioning is possible.
[0006]
By the way, the conventional carry-in apparatus is provided with a roller or belt mechanism on both sides of the insertion port, and both the roller and the belt are driven together to carry the disc, and both the roller and the belt depend on the size of the disc and the sandwiching position. Since they are configured to move together, the structure becomes complicated. Of course, it is also true that the number of parts is large, the manufacturing cost is high, and failure is easy.
[0007]
[Problems to be solved by the invention]
As described above, the conventional disk carry-in device has the above-described problems. The problems to be solved by the present invention are these problems, and provides a disk loading apparatus that can insert a disk from an insertion slot with a simpler structure, and can load and mount the disk to a turntable. The carrying-in apparatus of the present invention targets a 120 mm disk, and in the case of an 80 mm disk, an adapter is attached for use.
[0008]
[Means for solving the problems]
The disc carry-in device according to the present invention is configured so that a 120 mm disc can be inserted from an insertion port provided on the front panel so that the disc can be sandwiched and carried into the disc and correctly mounted on the turntable. . Therefore, rollers are attached near both sides of the insertion opening, the disc inserted by these rollers is sandwiched, and the disc is carried into the turntable side by rotating the roller.
[0009]
By the way, in the present invention, the driving roller shaft on one side is fixed to the chassis and can be driven to rotate by obtaining power from a motor attached at a predetermined position. Further, another second driving roller is provided on the back side of the first driving roller, and the second driving roller is pivotally supported by an arm that swings around the axis of the first driving roller, and the first driving roller. It can rotate in conjunction with. That is, only one side of the roller is driven to rotate.
[0010]
On the other hand, the idle roller provided on the opposite side is a non-driven roller, and is attached to the slider so that it can move in the direction perpendicular to the disk insertion direction (outward direction). And it connects with the arm which has attached the said 1st drive roller and the 2nd drive roller via a link. Therefore, if the idle roller is pushed by the disk and moves outward, the second drive roller also swings outward. The left and right drive rollers and idle rollers are biased by a spring force that can move toward the disc. Hereinafter, embodiments according to the present invention will be described in detail with reference to the drawings.
[0011]
【Example】
FIG. 1 shows a case where a part of a disk 4 is inserted into an insertion port 3 provided in a front panel 2 of the disk device 1. If a part of the disc 4 is inserted into the insertion port 3 of the disc device 1, it is pulled in by the built-in loading device and mounted on the turntable. And when taking out, it is discharged | emitted from the insertion port 3 with the same carrying-in apparatus.
[0012]
FIG. 2 shows an embodiment of a disk carry-in device according to the present invention. A first drive roller 5 is attached to a fixed position of the chassis on the left side of the insertion port 3, and an arm 6 that swings about the axis of the first drive roller 5 is provided. A drive roller 7 is attached. A first gear 8 is attached concentrically to the first drive roller 5, and a second gear 9 is attached concentrically to the second drive roller 7.
[0013]
If the intermediate gear 10 is interposed between the first gear 8 and the second gear 9 and meshes with the arm 6 and the first driving roller 5 is rotationally driven by a predetermined motor, the first gear is provided. 8, the second drive roller 7 rotates via the intermediate gear 10 and the second gear 9. Further, since the second driving roller 7 is attached to the tip of the swinging arm 6, the position of the second driving roller 7 is changed by the swinging of the arm 6. That is, according to the position of the disk 4 inserted from the insertion port 3, the arm 6 can swing so that it can contact the outer periphery of the disk.
[0014]
On the other hand, on the right side of the insertion port 3, the first roller 11 is rotatably supported by the slider 13, and the second roller 12 is also rotatably supported by the slider 13. The slider 13 can move outward along a guide groove (not shown). That is, according to the position of the disk 4 inserted from the insertion port 3, the slider moves outward so that the first roller 11 and the second roller 12 can contact the outer periphery of the disk.
[0015]
A right link 14 is attached to the slider 13 and extends to the insertion port side (center side). Another left link 15 is connected to the arm 6 and is rotatable about a shaft 16. The front end of the right link 14 and the front end of the left link 15 are connected to both ends of the middle link 17. Since the right link 14 extends from the slider 13 and does not swing, the connecting pin 19 of the middle link 17 is loosely fitted in an elongated hole 18 formed at the tip.
[0016]
By the way, if the disk 4 is inserted from the insertion port 3, the outer periphery of the disk 4 comes into contact with the first drive roller 5 and the first roller 11 as shown in FIG. 2. A sensor senses that the disc 4 has been inserted from the insertion port 3, and the first driving roller 5 is rotated by a motor. The rotation direction is a direction in which the disk 4 is drawn into the inside. If the disk 4 is further pressed from the near side, the disk 4 is drawn into the inside.
[0017]
Here, as the disk 4 enters from the insertion port 3, the distance between the first drive roller 5 and the first roller 11 increases, so the first roller 11 moves outward together with the slider 13. However, the spring force is urged so that the first roller 11 is always in contact with the outer periphery of the disk. The means for urging the spring force is not limited, and when urging directly to the slider 13, a coil spring is attached to the shaft 16 of the middle link 17, and the middle link 17 is urged to rotate clockwise. However, in the embodiment shown in the figure, a coil spring 20 is connected between the left link 15 and the right link 14.
[0018]
Then, if the disk 4 further enters, it moves to the back side and comes into contact with the second driving roller 7 on the left side and the second roller 12 on the right side. That is, the disk 4 is sandwiched between four rollers, the first driving roller 5 and the second driving roller 7, and the first roller 11 and the second roller 12, and the first driving roller 5 and the second driving roller 7 rotate together. By driving, the disk 4 is carried into the back side. That is, if it reaches this position, it is carried in alone without pressing the back of the disk by hand.
[0019]
In FIG. 2, the state of being sandwiched by four rollers is not shown, but the disk 4 reaches the position of the turntable by being drawn further from this state. If it is mounted on the turntable, the second drive roller 7 and the second roller 12 located on the back side must be separated from the disk 4 as shown in FIG. Since the second drive roller 7 on the left side is attached to the tip of the arm 6 and the second roller 12 on the right side is attached to the slider 13, the left and right links 14, 15 connecting the arm 6 and the slider 13 are provided. It can be done by operating. Further, the second drive roller 7 and the second roller 12 can be separated from the disk 4 by rotating the middle link 17 counterclockwise.
[0020]
As described above, the disk carry-in device of the present invention is such that the first drive roller and the second drive roller are attached to one side of the insertion port, and the first roller and the second roller are provided on the other side. The following effects can be obtained.
[0021]
【The invention's effect】
In the disk carry-in device of the present invention, the first drive roller provided on one side of the insertion slot is fixed at a fixed position, and the second drive roller is attached to the tip of the swing arm. The first and second rollers on the opposite side are attached to a slider that moves outward. Therefore, the disk inserted from the insertion port can be held by the arm on one side and the slider can be moved to hold the disk and be reliably pulled by the driving roller. In addition, since the present invention targets only a 120 mm disk, the movement range of the arm and slider is short, and a predetermined spring can be used in a range of an appropriate load and elongation rate. The power stabilizes.
[0022]
In this way, the carrying-in apparatus of the present invention uses only one roller as a driving roller, and also allows only the opposite roller to move outward in response to the entry of a disk, that is, The structure of the apparatus is simplified by making the right and left rollers as drive rollers and not moving outward as in the prior art, and the track of the loaded disc is stabilized by being constant.
