Abstract

PURPOSE:To accurately and easily remove dust accumulated on an objective lens of an optical pickup by providing a mechanism, which removes dust on the objective lens, in a cartridge which can be inserted to an optical disk device. CONSTITUTION:A cartridge 1 is inserted to the optical disk device so that a block 6 and a ball 8 are placed above a turntable 22 of a motor 21 provided for the optical disk device and above an objective lens 24 of a positioned optical pickup 23 respectively. When the cartridge 1 is completely inserted to the optical disk device in this state, the turntable 22 lifts the block 6 and a rod 11 is shaked with a bracket 7a as the center, and the ball 8 presses a cleaning sheet 2 to the upper face of the objective lens 24, and a roll 4 is rotated by a driving mechanism 5 to move the cleaning sheet 2, and dust on the objective lens 24 is removed, and further, an air pipe 16 is connected to the other end of an air pipe 15 to blow air in the direction of an arrow 20, thereby removing dust on the objective lens 24.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an optical pickup cleaner, and more particularly to an optical pickup cleaner that removes dust from an objective lens when an optical disk device is mounted.

Conventional technology In the past, dust accumulated on the objective lens of an optical pickup was removed by removing the cover of the optical disk device and removing it directly by hand using a cotton swab or silbon paper soaked with solvent on the objective lens. Ta.

Problems to be Solved by the Invention The cleaning of the objective lens of the conventional optical pickup described above was carried out manually by disassembling a part of the optical disk device, which was extremely time-consuming and labor-intensive. There are disadvantages in that the objective lens may be damaged, the internal mechanism of the actuator may be damaged, and there may be individual differences in the state of completion of cleaning.

The present invention has been made in view of the above-mentioned conventional circumstances,
Therefore, an object of the present invention is to eliminate the above-mentioned disadvantages inherent in the conventional technology and to provide a new reach that makes it possible to easily and accurately remove dust accumulated on the objective lens of an optical pickup. be.

Means for Solving the Problems In order to achieve the above object, an optical pickup cleaner according to the present invention includes a cartridge that can be inserted into an optical disc device, and a block that is disposed inside the cartridge and receives a protrusion from the outside. , a ball that swings in the opposite direction in conjunction with the block to bring the cleaning sheet into contact with the objective lens, a mechanism that winds up the cleaning sheet arranged in the direction in which the ball moves, and a mechanism that is placed near the line. In this way, dust on the objective lens of the optical pickup can be accurately removed.

Embodiment Next, a preferred embodiment of the present invention will be specifically explained with reference to the drawings.

FIG. 1 is a perspective view showing an embodiment of an optical pickup cleaner according to the present invention, and FIG. 2 is a longitudinal sectional view of FIG. 1.

Referring to FIGS. 1 and 2, a cartridge 1 having a flat plate-like outer shape and a space inside has a hole 10 and a long hole 9 in its bottom surface. A rectangular block 6 is disposed inside the cartridge 1 above the hole 10, and the block 6 is movably connected to one end of the rod 11 by a bracket 7b. Further, a ball 8 is provided at the other end of the rod 11, and the rod 11 is swingably attached to a bracket 7a at its center. Here, the ball 8 is located above the elongated hole 9, and a strip-shaped cleaning sheet 2 is provided between the line 8 and the elongated hole 9. The cleaning sheet 2 is sent out from the roller 3 and wound around the roller 4, and before and after passing through the elongated hole 9, the cleaning sheet 2 passes through so as to come into contact with a bar 12 for preventing loosening. Here, the roller 4 is rotated by a drive mechanism 5 to wind up an appropriate amount of the cleaning sheet 2 at any time. Further, an air pipe 15 is laid on the bottom surface of the cartridge 1 so that the nozzle portion thereof is located near the line 8, and the other end of the air pipe 15 is located outside the cartridge 1 through a circular hole 17. Further, the air pipe 15 is fixed to the bottom surface of the cartridge 1 with a stopper 18.

The optical pickup cleaner having the above-described structure inside the cartridge 1, as shown in FIG.
Insert the cartridge 1 into the optical disc device so that the block 6 is positioned above and the ball 8 is positioned above the objective lens 24 of the positioned optical pickup 23. In this state, the cartridge 1 is completely inserted as shown in FIG. When inserted into the optical disc device, the turntable 22 lifts the block 6 and the rod 11 swings around the bracket 7a.
The ball 8 presses the cleaning sheet 2 against the upper surface of the objective lens 24, and the driving mechanism 5 rotates the roller 4 at an appropriate speed to move the cleaning sheet 2, thereby removing dust on the objective lens 24. Air piping 16 is connected to the other end of 15 and air is blown in the direction of arrow 20 by a compressor or the like, so that air is blown out from the nozzle portion and dust on objective lens 24 is removed.

As described in detail, the optical pickup cleaner of the present invention includes a cartridge that can be inserted into an optical disc device, and a protrusion (in this embodiment, a turntable) disposed inside the cartridge that protrudes from the outside. A receiving block, a ball that moves in the opposite direction in conjunction with the block, and a cleaning sheet arranged in the direction in which the ball moves.
By providing a winding mechanism and an air pipe placed near the wire to feed air, it is possible to easily and uniformly remove dust accumulated on the objective lens of the optical pickup.
