DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Below, the detailed description and technical contents of the present invention are to be stated in cooperation with the attached drawings.
Refer to FIG. 1, FIG. 2, FIG. 3A, and FIG. 3B, which are respectively a perspective view, an exploded view and sectional views schematically showing the appearance, the structure and the operation of the present invention. The present invention is a surface treatment device for optical discs, which is used to destroy or enhance the read and write function of an optical disc 5 (shown in FIG. 3B). Different surface treatments can disable or enhance the read and write capability of the optical disc 5 so that the data stored in the optical disc 5 will be destroyed or protected. The surface treatment device for optical discs of the present invention has a base 10, and one side of the base 10 has a pivotal element 100, and a pin 102 can be inserted through the pivotal element 100 to pivotedly interconnect the base 10 and an upper cover 20 so that the upper cover 20 may be opened or closed. A gripping space 15 is formed between the base 10 and the upper cover 20, and one side of the optical disc 5 is gripped in the gripping space 15. Opposite to the pivotal element 100 and across the gripping space 15, an accommodation hole 101 is formed on the other side of the base 10 to accommodate a rotary axle 11 that can penetrate the central hole 52 of the optical disc 5 to install the optical disc. A gripping plate 30 is disposed in the rotary axle 11 and faces one surface of the optical disc 5. A grinding element 103 is installed on the base 10 and disposed between the pivotal element 100 and the rotary axle 11. The grinding element 103 may be a rough surface used to roughly abrade the printed surface 50 of the optical disc 5, or a soft surface used to clean or repair the protection layer 51 of the optical disc 5. The type of the grinding element 103 is selected according to the aim of the surface treatment. The rough surface can roughly abrade the printed surface 50 and destroy the stored data; the soft surface can refine the protection layer 51 of the optical disc 5 and benefit the read and write operation of an optical disc drive.
An installation hole 201 is formed in the upper cover 20 and disposed corresponding to the rotary axle 11, and a connection element 21 is inserted through the installation hole 201. A position-limiting flange 212 protrudes from the connection element 21 and is disposed on the position where the gripping space 15 is formed. A through hole 211 is installed in the connection element 21 along the radial direction of the connection element 21. One gripping plate 30 is disposed on one side of the position-limiting flange 212 and cooperates with the other gripping plate 30 to grip the optical disc 5. A slide block 23 is installed inside the through hole 211 and is kept inside the through hole 211 by the position-limiting flange 212. The slide block 23 has a fitting hole 230, and the fitting hole 23 has a fitting slot 231. The rotary axle 11 has a fitting portion 110, which has a shape matching the fitting slot 231 and cooperates with the fitting slot 231 to perform movement transmission. One side of the connection element 21 (near the gripping space 15) has two pivotal holes 210 used to pivotedly connect the connection element 21 with a crank 22. The crank 22 can be accommodated on an accommodation portion on the upper cover 20 and can be rotated pivotedly to a rotation position. One end of the crank 22 (opposite to the end pivotedly connected with the connection element 21) has a rotary knob 220 for the holding of the user's hand; thereby, the user can rotate the crank 22 with his hand.
Refer to FIG. 4A, FIG. 4B and FIG. 5 diagrams respectively showing the operations of a portion of parts and the entire device of the present invention schematically. An elastic element 12 is installed in the pivotal connection portion of the base 10 and the upper cover 20 so that the base 10 and the upper cover 20 are normally kept in gripping state. When the optical disc 5 are mounted on the rotary axle 11 with the rotary axle penetrating the central hole 52 of the optical 5, the gripping plates 30 of the rotary axle 11 and the connection element 21 respectively contact the lower surface and upper surface of the optical disc 5 and cooperate to grip the optical disc 5. When the crank 22 is pivotedly rotated to the rotation position, the slide block 23 will be displaced horizontally so that the fitting slot 231 of the slide block 23 will engage with the fitting portion 110 of the rotary axle 11. Thereby, when the user rotates the crank 22 with the rotary knob 220, the rotary axle 11 is driven to rotate, and the optical disc 5 gripped by the gripping plates 30 is also driven to rotate. When the user intends to destroy the data stored in the optical disc 5, he should select a rough surface as the grinding element 103 so that the grinding element 103 will roughly abrade and destroy the printed surface 50 of the optical disc 5. When the user intends to enhance the read and write capability of the optical disc 5, he should select a soft surface (such as a chamois leather or a soft fabric) as the grinding element 103 so that the dirt on the protection layer 51 of the optical disc 5 can be cleaned.
In one embodiment of the present invention, when the protection layer 51 is seriously damaged, a repair liquid is uniformly applied onto the protection 51 to repair the protection layer 51 and improve the read and write capability of the optical disc 5. Refer to FIG. 6 an exploded view schematically showing one embodiment of the present invention. In this embodiment, the base 10 has a bottom cover 14, and the bottom cover 14 has a concaved region 13 used to accommodate a storage bottle 40 in which the repair liquid is stored. When the optical disc 5 needs repairing, the user takes out the storage bottle 40 and applies the repair liquid onto the soft surface and then utilizes the device of the present invention to uniformly distribute the repair liquid onto the protection layer 51; thereby, the read and write function of the optical disc 5 can be improved.
The present invention does not have to hold the entire optical disc 5 inside the device but only needs to grip one side of the optical disc 5; therefore, the device of the present invention has a smaller size and occupies less space. Further, the surface treatment (rough abrasion, cleaning or repairing) of the printed surface 50 or protection layer 51 of the optical disc 5 can be performed via manually operating the crank 22. Therefore, the device of the present invention has a simpler structure than that of the conventional technology and is very suitable to the users who process only a smaller quantity of optical discs. Accordingly, the present invention possesses the novelty and non-obviousness demanded by the regulation for applying a patent.
Those described above are only the preferred embodiments to clarify the present invention. However, it is not intended to limit the scope of the present invention. Any equivalent modification and variation according to the spirit of the present invention is to be also included within the scope the claims of the present invention stated below.
