Abstract

PURPOSE:To offer a structure capable of cleaning a lens in a CD player independently. CONSTITUTION:This device is provided with a fiber flocked member 5 supported by an axis freely rotatably to a cramper 4, a circuit driving the lens 3 of an optical pickup in the direction of the fiber flocked member 5 and a turning table 1 holding and rotating a disk 10. By rotating the turning table 1 when the disk 10 is unloaded, the cramper 4 is rotated, the fiber flocked member 5 is brought into contact with the lens 3 of the optical pickup and the lens 3 is cleaned.

Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a CD player whose optical pickup lens can be cleaned.

0002

2. Description of the Related Art In recent years, CD players have become quite popular. Among these, the most popular type is the one in which the playing status cannot be seen after loading, and for cleaning the optical pickup lens, specialized discs with flocked areas, such as those shown in Japanese Patent Publication No. 1-43386, are sold and used. .

0003

[Problem to be solved by the invention] However, the conventional C
The D player has a problem in that even though the optical pickup cannot be seen and cleaning is necessary, a separately sold cleaning disk must be installed and operated.

[0004] In view of the above-mentioned conventional problems, the present invention has been made to
The purpose of this invention is to provide a structure that allows the player to clean the lens by itself.

[0005]

[Means for Solving the Problems] In order to solve the above problems, the CD player of the present invention includes a flocking member rotatably supported by a clamper, and a circuit for driving the lens of an optical pickup toward the flocking member. , which has a turntable that holds and rotates the disc.

[0006]

[Operation] According to the above-described structure of the present invention, when the turntable rotates, the clamper and the flocking member rotate, and when the lens of the optical pickup is driven toward the disk side, the lens is cleaned by the flocking member.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS A CD player according to an embodiment of the present invention will be described in detail below with reference to the drawings.

FIG. 1 shows a CD in a first embodiment of the present invention.
This is a side sectional view of the player, showing a state without a disc.

In FIG. 1, 1 is a turntable that rotatably supports a compact disc, 2 is a motor that rotates the turntable, 3 is an optical pickup lens that reads the signal side of the CD, and 4 is a rotary unit that rotates the disc with the turntable 1. A clamper for fixing the scissor disk to the turntable, 5 a flocking member rotatably supported by the clamper 4, 6 a lens drive circuit for the optical pickup, 7 a motor drive circuit, 8 an operation button, 9 a clamper 4 A magnet fixed to the disc generates the force to sandwich the disc.

The operation of the CD player configured as described above will be explained below.

First, when the operation button 8 is operated without a disk, the motor 2 and turntable 1 rotate, and the clamper 4 also rotates by the force of the magnet 9. When the clamper 4 rotates, the flocking member 5 also rotates. At that time,
If the lens 3 is driven toward the flocking member by the lens drive circuit 6 of the optical pickup, the flocking member 5 will move the lens 3 under its own weight.
You can clean the lens surface by touching it. At this time, the rotation and driving time remains constant and there is no unnecessary rotation.

FIG. 2 is a side view when there is a disk. At this time, the clamper 4 is held down by the disk 10 by the attraction force of the magnet 9, and the flocking member 5 is held against the clamper 4.
It is stored inside and there is no problem in rotating it.

FIG. 3 is a view in the direction of arrow A in FIG. 1, and is a side view of the clamper 4 and the flocking member 5 as seen from the axial direction. Figure 3 (
3(a) shows the state with the disk 10, and FIG. 3(b) shows the state without the disk 10. In the figure, the shaft 5a of the flocking member 5 is supported by the clamper 4 and is rotatable, and in FIG. However, Fig. 3(b
), there is no disk 10 and the weight balance of the flocking member 5 is heavier on the left side than on the right side with respect to the center of the shaft 5a, so the flocking member 5 rotates counterclockwise and the flocking part 5b is attached to the lens 3 of the optical pickup. come into contact with. However, in order to restrict the range in which the flocking member 5 can rotate so as not to get in the way when inserting the disc, the stopper part 5c is attached to the end 4 of the clamper 4.
It is in contact with a.

Further, FIG. 4 shows a state in which the flocking member 5 is biased counterclockwise by the spring 11. In addition,
In this embodiment, the flocked portion 5b of the flocked member 5 is made of long hair, but it may be made of cloth or felt.

[0015]

As described above, according to the CD player of the present invention, the lens can be cleaned by the player alone without the need for a separately sold disk dedicated to cleaning.

[Brief explanation of the drawing]

FIG. 1 is a side view of a CD player in a state without a disc in an embodiment of the present invention.

FIG. 2 is a side view of the CD player in the embodiment of the present invention without a disc.

3(a) A side view showing a state in which a disk is installed as viewed from arrow A in FIG. 1; (b) A side view showing a state in which a disk is not installed as viewed from arrow A in FIG.

FIG. 4 is a side view showing a state in which the flocking member 5 is biased counterclockwise in FIG. 3;
