Abstract

<P>PROBLEM TO BE SOLVED: To provide an optical pickup lens cleaner where the problem that removed dust, trash, etc. occasionally remain at the edge of an objective lens of an optical pickup is eliminated. <P>SOLUTION: A center hole 2 is formed at a cleaning disk 1, and a cleaning member 3 whose tip is V-shaped is provided inclining from the rotating direction of the cleaning disk 1 on a rear surface between contacts crossing with a tangential line from the center of the cleaning disk 1. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

Technical field to which the invention belongs

The present invention relates to cleaning of an optical pickup objective lens.

Many optical pickup lens cleaners currently on the market are provided with a cleaning member such as one or a plurality of brushes on the disk surface, and the cleaning member comes into contact with the objective lens of the optical pickup by reproducing the disk with a player. The dirt of the objective lens of the optical pickup is cleaned.

Problems to be solved by the invention

However, although dust and dust can be removed with the cleaning disk, the cleaning member is provided substantially perpendicular to the cleaning disk, and the cleaning disk rotates in one direction. May remain on the edge of the objective lens of the optical pickup, and may gradually accumulate, causing problems in the functions of the objective lens of the optical pickup and peripheral devices.

Means to solve the problem

According to the present invention, at least one or more flexible cleaning members (for example, brushes) are provided on a cleaning disk, the tip of the cleaning member is V-shaped, and the tip of the cleaning member is rotated by the cleaning disk. By being inclined in the direction, the cleaning member comes into contact with the entire edge of the objective lens spherical surface of the optical pickup and reaches the vertex of the objective lens in a distributed manner. It is configured to remove dust and dirt, including dust and dirt attached to the edges.

Further, the tip of the cleaning member having a V-shape is configured so as to be able to cope with the degree of contamination of the optical pickup objective lens, such as a crossed one and a slight gap.

Embodiments and embodiments of the invention

The configuration of the present invention will be described with reference to FIGS.
A central hole 2 is provided at the center of the cleaning disk 1, and a cleaning member 3 is provided on the back surface between the contacts that intersects the tangent line at a right angle from the center of the central hole 2. The cleaning member 3 has a V-shaped tip, and The front end is provided to be inclined in the rotation direction of the cleaning disk 1.

An embodiment of the present invention will be described with reference to FIGS.
The tray 6 of the player 5 is ejected, the cleaning disk 1 is set in the tray 6, and the play button is pressed to enter the play state. Next, when the objective lens 4 of the optical pickup is moved to the cleaning area, the cleaning disk 1 starts operating, and the cleaning member 3 cleans the objective lens 4. 4 to 7 show examples of cleaning. 8 and 9 show the movement of the cleaning member 3 and the locus 7 during cleaning.

The invention's effect

The present invention is implemented in the form as described above, and has the effects described below.

Because the cleaning member is made of a flexible material, its tip is V-shaped, and the tip is tilted in the direction of rotation of the cleaning disk, so that the cleaning member is dispersed throughout the objective lens, ensuring dust, dust, etc. You can praise and catch.

The above-described material and form do not damage the objective lens during cleaning.

By making the tip of the cleaning member V-shaped and crossing the tip, or conversely having a slight interval, a configuration in which the cleaning can be controlled is made possible.

FIG. 1 is a plan view showing a cleaning disk. FIG. 2 is a front view showing a cleaning disk. FIG. 3 is a perspective view showing an embodiment of a cleaning disk and a player. 5 is a longitudinal sectional view showing the embodiment. FIG. 6 is a detailed plan view showing the embodiment in which the objective lens and the cleaning member V-shaped tip are slightly spaced. FIG. 7 is a longitudinal sectional view showing the embodiment. FIG. FIG. 9 is a detailed plan view showing the movement of the cleaning member relative to the objective lens.

Claims (3)

In a lens cleaner for cleaning dirt on an objective lens of an optical pickup, at least one cleaning member (for example, a brush) having a flexible state is attached to a cleaning disk, and the tip of the cleaning member is V-shaped. An optical pickup lens cleaner characterized in that the tip of the cleaning member is provided so as to be inclined in the rotation direction of the cleaning disk. The optical pickup lens cleaner according to claim 1, wherein the cleaning member is provided so that the V-shaped ends thereof intersect each other. 3. The optical pickup lens cleaner according to claim 1, wherein the V-shaped tip of the cleaning member does not intersect and is provided with a slight interval.
