[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cleaning device for a pickup of an optical disk player.

[0002]

2. Description of the Related Art Generally, in an optical disk player,
The optical pickup is arranged on the lower surface of the disk. Therefore, in this configuration, dust easily accumulates on the pickup, the output of the signal reading light from the pickup decreases, and the signal may not be read.

Therefore, conventionally, Japanese Utility Model Application Laid-Open No. 2-80316
Japanese Patent Application Publication (G11B7 / 12) proposes a cleaning device for removing dust attached to a pickup.

[0004] However, the above configuration has a disadvantage that a cleaning device for the optical pickup is separately required.

[0005]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned drawbacks, and has as its object to provide a cleaning apparatus having a simple structure and requiring no additional components.

[0006]

According to the present invention, there is provided a turntable on which a disk driven by a spindle motor is mounted, a tray on which the disk is mounted and moved to a position of the turntable in a player, and recording on the disk. An optical pickup device having an objective lens for reproducing the obtained signal, and a brush member for removing dust from the objective lens of the optical pickup device, wherein the brush member is A cleaning device for an optical pickup, which is provided at a lower portion of a tip portion of a tray.

[0007]

According to the present invention, the objective lens of the pickup is cleaned every time the disc is replaced by using the above-described structure, so that the output light from the pickup is not reduced.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. In FIG. 1, D is a disc, 1 is a tray for conveying the disc D into the player, 2 is a diagonally cut head cleaning brush provided below the tip of the tray 1, 3 is a spindle motor, , A turntable; 100, a pickup device; 90, an objective lens for outputting output light for reading; 93, a base of the pickup device; 103, a tilt cam for making the pickup device 100 perpendicular to a disk;
Is an engagement piece for engaging the pickup device 100 with the tilt cam 103, and 95 is a fulcrum of rotation with respect to the tilt of the pickup device.

Next, the operation of the embodiment of the present invention will be described.
In the embodiment of the present invention, when the disc D is placed on the turntable 4, the motor 3 is raised. These configurations have been proposed by the present applicant in Japanese Patent Application No. 2-87141.

Then, as shown in FIG. 2, the tray 1 on which the disk D is placed moves in the direction of the arrow. At this time, the pickup device 100 is in an inclined state, and when the tray 1 further moves toward the back in the player, the brush 2 provided at the lower portion of the tray 1 contacts the objective lens 90 as shown in FIG. By moving, the dust attached to the objective lens 90 can be wiped.

When the tray 1 reaches the inside of the player, the brush 2 moves to a position distant from the pickup device 100, the disc D is placed on the turntable 4, the tilt cam 103 operates, and the pick-up is performed. Apparatus 10
From 0, the signal can be reproduced.

When taking out the disc D, the pickup device 100 is tilted by the tilt cam 103, the disc D is placed on the tray 1, and the tray 1 is moved out of the player. At this time, the brush 2 is
Contact can wipe the dust.

[0013]

As described above, according to the present invention, it is possible to remove dust from the objective lens of the pickup with a simple structure and without damaging the lens surface.
