The present invention relates to a slot-in type optical disc storage system. More particularly, in an optical disc storage apparatus using a slot-in type optical disc, two optical disc changers are provided, and a plurality of optical disc changers are provided around the optical disc storage apparatus. Relates to a type optical disk storage system in which a slot is radially installed.

Due to the development of technology and the pursuit of human convenience, the slot-in type information storage device that can be inserted and removed more easily and can be used in various postures is improved by improving the structure of the existing tray method. Developed.

Accordingly, as shown in FIG. 1A, the disc is inserted with the optical disc storage device lying horizontally, or the optical disc inserting portion of the optical disc storage device is vertically inserted as shown in FIG. 1B, or the optical disc is inserted in FIG. 1C. As shown in the drawing, the optical disc can be inserted from the top to the bottom with the optical disc inserting portion of the optical disc storage device facing upward.

The optical disk storage device, which is a slot that can operate as described above, is not a structure in which a disk is inserted / removed, unlike a conventional tray type optical disk storage device, in which a disk is inserted / removed by moving a tray. The sensor detects the presence of the disk by the sensor, and the disk label surface contacts the disk guide, and the data surface contacts the roller to guide the disk to the disk guide by the rotation of the roller while the disk is inserted / removed.

In addition, when the disc is placed at a certain position when the disc is loaded by the roller, a disc stopper is installed so that the disc is loaded on the disc seating surface of the turntable.

The mechanism of the slot-in type optical disc storage device will be described in detail with reference to the accompanying drawings.

As shown in FIG. 2, when the optical disc 2 is inserted into the optical disc storage device 1, a sensor 5 that determines whether the optical disc 2 is inserted is positioned above and below the optical disc 2. Thus, the insertion of the optical disc 2 is sensed.

At this time, the roller 3 starts to rotate, and the optical disk 2 inserted more than a predetermined distance is bitten by the roller 3 and the disk guide 4 thereon and into the optical disk storage device 1. Will enter.

The roller 3 has the same shape as abutting two cones.

In addition, the disk guide 4 has a shape in which a small-shaped protrusion is formed on a flat plate to minimize the damage of the optical disk on the contact surface while reducing the contact area with the optical disk 2.

The sensor 5 is approximately installed at the center of the optical disk storage device 1 because the sensor 5 is the first position to sense when the optical disk 2 is inserted.

In addition to the sensor 5, sensors 6 and 7 for detecting the current position of the optical disk 2 are further installed, and the installation positions thereof are approximately one each at the front and rear of the roller 3, and at the front. The sensor 6 positioned is installed at a position capable of sensing the outermost side of the optical disc 2, and the sensor 7 positioned at the rear is approximately halfway between the sensor 5 and the sensor 6. Is installed on.

3 is a schematic view of the optical disk insertion process as seen from the upper side, the figure on the left shows the initial state of the optical disk insertion, the figure on the right shows the state in which the optical disk is seated on the spindle motor in the state that the optical disk can be inserted and loaded. It is shown.

3 shows an optical disc 2 being inserted into the optical disc storage device 1 and being pushed downward by the roller 3.

The optical disc 2 is continuously pulled down by the roller 3 until it reaches the stoppers 9 and 10.

The right side of FIG. 3 shows that the optical disk 2 touches the stoppers 9 and 10 and pushes one end of the lever 11 so that the lever 11 rotates counterclockwise. The projection is lifted up by h.

When the cam 12 is lifted by h, as shown in Figs. 4A to 4C, the mounting process of the optical disc 2 to the spindle motor 8 is performed.

As shown in FIG. 4A, the optical disk 2 is inserted by the roller 3 and the disk guide 4, and the clamp member 13 is separated from the spindle motor 8 by a predetermined distance.

As shown in FIG. 4B, the optical disc 2 enters the optical disc storage device 1 and comes into contact with the stoppers 9 and 10, and the cam 12 is raised by h due to the operation of the lever 11. Done.

Therefore, due to the rise of the cam 12 as shown in FIG. 4C, the cam 12 lowers the clamp member 13 so as to push the optical disc 2 down from above and rest on the upper surface of the spindle motor 8. do.

At this time, the stoppers 9 and 10 are separated from the optical disc 2 and loading starts. In addition, the roller 3 and the disc guide 4 also move away from the optical disc 2 so that contact with the optical disc 2 does not occur.

The ejection action of the optical disc 2 takes place in the reverse order of the above process.

However, such a conventional slot optical disk storage device is inserted and ejected by a single inlet installed in the drive, so when the replacement of the optical disk ejects the optical disk already inserted in the optical disk storage device, and then back to the same inlet Should be inserted.

5 shows an optical disk storage system of the related art using the optical disk storage device as described above.

There are N optical disks in the system of the optical disk changer 20. The optical disk storage device 1, which is a slot on the right side, moves up and down in the optical disk storage system 30 to load optical disks at arbitrary positions. Play the disc.

Marked with a dashed line in the optical disc storage system 30 indicates a virtual position when the optical disc storage device 10 moves to an arbitrary position.

However, the optical disc storage system 30 having the above structure has a structural limitation in dealing with many discs. In particular, a system with a constraint on height has a problem that more and more disks are difficult to cope with.

FIG. 6A illustrates the optical disk 101 being inserted into the optical disk storage device 100 used in the embodiment of the present invention, and FIG. 6B illustrates the optical disk storage device 100 according to the embodiment of the present invention. The optical disc 101 is mounted on the spindle motor 140 and shows a state of being ready for loading, and FIG. 6C shows a state in which the optical disc 101 is discharged from the optical disc storage device 100 according to the embodiment of the present invention. It is shown.

7 is a view of the optical disk storage device 100 according to the embodiment of the present invention seen from above.

In the optical disk storage device 100 used in the present invention, optical disk entrances and exits 102 and 103 are formed at both sides. Therefore, the angles between the two optical disk inlets and outlets 102 and 103 are 180 degrees, and the angles may be smaller than 180 degrees.

Each of the optical disc inlets and outlets 102 and 103 is formed with a slot mechanism.

The slot-in mechanism includes rollers 121 and 131, disc guides 120 and 130, and a sensor (not shown).

The rollers 121 and 131 may be positioned below the optical disc 101, that is, below the recording surface of the optical disc 101, and may vertically reciprocate to be in contact with or separated from the optical disc 101.

In addition, the rollers 121 and 131 receive torque from a driving source (not shown) and rotate in a clockwise or counterclockwise direction to provide a horizontal force for inserting or ejecting the optical disk 102.

The rollers 121 and 131 have the same shape as abutting two cones.

The rollers 121 and 131 may be made of a soft material such as urethane, PE, or the like so as not to damage the optical disc 101.

At this time, since the synthetic resin material is easy to bend due to the small rigidity, the shafts 122 and 132 are interpolated inside the rollers 121 and 131 to reinforce the bending rigidity of the rollers 121 and 131.

In addition, the rollers 121 and 131 are preferably supported by rotation with a bearing having a very small rotational resistance so that rolling resistance is small.

The disk guides 120 and 130 are located above the optical disk 101, that is, on the label surface of the optical disk 101, and can vertically reciprocate. Therefore, the optical disk 101 may be in contact with or separated from each other, and serves to provide a vertical drag that may generate frictional force between the rollers 121 and 131 and the optical disk 101.

The disc guides 120 and 130 are formed with flat protrusions having a small thickness, and have a shape capable of minimizing damage to the optical disc 101 at the contact surface while reducing the contact area with the optical disc 101.

Although not shown in the drawings, as in the prior art, sensors capable of detecting the insertion of the optical disc 101 are provided at the two optical disc inlet / outlets 102 and 103, and the positions and the number of installation thereof are the same as in the prior art.

A stepping motor 140 is installed at the center of the two optical disk entrances and exits 102 and 103.

If the angle between the two optical disc inlet / outlets 102 and 103 is smaller than 180 °, the stepping motor 140 is formed at the intersection of the straight lines extending by the two rollers 121 and 131 in the horizontal movement direction of the optical disc 101. Is installed.

The clamping mechanism 110 is installed above the stepping motor 140, and the clamping mechanism 110 should be installed so as not to interfere with the rollers 121 and 131 and the guide mechanisms 120 and 130. In the example, the optical disks are formed in a direction perpendicular to an imaginary straight line connecting the entrance and exit ports 102 and 103.

The mechanism for pressing the optical disk 101 of the clamping mechanism 110 may be implemented using a known mechanism such as a mechanical mechanism such as a lever and a cam mechanism or an electrical mechanism such as a step motor as in the prior art.
