Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a cleaning device for a pickup of an optical disc player.

[0002]

[Prior Art]

 In general, an optical disc player has a structure in which an optical pickup is arranged on the lower surface of a disc. Therefore, in this configuration, dust is likely to be accumulated on the pick-up, the output of the signal reading light from the pickup is reduced, and the signal may not be readable.

Therefore, conventionally, there has been proposed a cleaning device such as Japanese Utility Model Laid-Open No. 2-80316 (G11B7 / 12) for removing dust on a pickup.

However, the above-mentioned configuration has a drawback that a separate cleaning device for the optical pickup is required.

[0005]

[Problems to be solved by the device]

 The present invention is intended to solve the above-mentioned drawbacks, and an object of the present invention is to provide a cleaning device having a simple structure and requiring no additional parts.

[0006]

[Means for Solving the Problems]

 The present invention provides a turntable on which a disc driven by a spindle motor is placed, a tray on which the disc is placed and moved to a position of a turntable in a player, and a signal for reproducing a signal recorded on the disc. In a cleaning device for an optical pickup device, which comprises an optical pickup device provided with an objective lens and a brush member for dusting the objective lens of the optical pickup device, the brush member is a lower part of the tip of the tray. It is an optical pick-up cleaning device characterized in that it is provided in the.

[0007]

[Action]

 With the configuration described above, the present invention cleans the objective lens of the pickup every time the disc is replaced, so the output light from the pickup is not reduced.

[0008]

【Example】

 Hereinafter, embodiments of the present invention will be described with reference to the drawings. In FIG. 1, D is a disc, 1 is a tray for transporting the disc D into the player, 2 is a head cleaning brush provided under the tip of the tray 1 and obliquely cut, 3 is a spindle motor, and 4 is a spindle motor. Is a turntable, 100 is a pickup device, 90 is an objective lens for outputting the reading output light, 93 is the base of the pickup device, 103 is a tilt cam for making the pickup device 100 perpendicular to the disc, and 94 is a pickup. An engaging piece 95 for engaging the device 100 and the tilt cam 103 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 disk D is placed on the turntable 4, the motor 3 is raised. The applicant has proposed these configurations in Japanese Patent Application No. 2-87141.

Then, as shown in FIG. 2, the tray 1 on which the disc 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 is further moved to the inner side of the player, the brush 2 provided on the lower portion of the tray 1 comes into contact with the objective lens 90 as shown in FIG. By moving, dust on the objective lens 90 can be wiped.

When the tray 1 reaches the inner part of the player, the brush 2 moves to a position away from the pickup device 100, the disc D is placed on the turntable 4, the tilt cam 103 operates, and the pickup is performed. The signal can be reproduced from the device 100.

Then, when the disc D is taken out, 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 to the outside of the player. Also at this time, the brush 2 can contact the objective lens 90 and wipe the dust.

[0013]

[Effect of the device]

 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.
