Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to an ultrasonic recording disk cleaner for cleaning recording disks such as compact disks and laser disks.

(Prior Art) Conventionally, when cleaning a recording disk such as a compact disk, an ultrasonic recording disk cleaner is generally used.

This ultrasonic recording disk cleaner has an ultrasonic generator attached to a cleaning tank containing a cleaning liquid.The entire recording disk, such as a compact disk, is immersed in this cleaning liquid and the ultrasonic generator is driven. . As a result, cavitation occurs in the cleaning liquid, and dirt adhering to the recording disk is removed.

(Problem to be solved by the invention) As described above, in the conventional ultrasonic recording disk cleaner, the recording disk is cleaned, but in order to remove the cleaning liquid adhering to the recording disk, after this cleaning step, The recording disk was air-dried, or the cleaning liquid was absorbed using cloth or paper.

However, the method of removing the cleaning liquid by air drying has the problem that the removal time is extremely long, and the method of blotting it with cloth etc. causes the fibers of the cloth etc. to adhere to the recording disk. Otherwise, there was a problem that scratches occurred.

In addition, in the conventional ultrasonic recording disk cleaner described above, since the recording disk is cleaned in one cleaning tank, when cleaning a heavily soiled recording disk, the dirt removed from this recording disk is washed away. There was a problem in that it adhered to the recording disk again at the end of the process.

Furthermore, in the conventional ultrasonic recording disk cleaner, the entire recording disk is immersed in the cleaning liquid during the cleaning process, which poses the problem that a large amount of cleaning liquid must be stored in the cleaning tank.

In view of the above-mentioned conventional problems, the purpose of the present invention is to not only clean the recording disk but also to dry it in a short time, to clean it efficiently with a small amount of cleaning liquid, and to improve the recording disk. To provide an ultrasonic recording disk cleaner capable of rinsing a disk and preventing the dirt removed from the recording disk by this rinsing step from being reattached.

(Means for Solving the Problems) In order to solve the above problems, the invention of claim (1) includes a recording disk such as a compact disk in a cleaning tank equipped with an ultrasonic generator and containing cleaning liquid. In an ultrasonic recording disk cleaner that cleans the recording disk by immersing the recording disk, the cleaning tank is provided with a cleaning chamber storing a cleaning liquid and a rinsing chamber storing a rinsing liquid on the left and right sides of the cleaning tank, and is connected to the recording disk and cleaning the recording disk. a rotational drive means for rotating the disk; a fixing means for the rotational drive means for fixing the rotational drive means; and a fixing means for the rotational drive means, the fixing means being removably inserted into the cleaning tank when the recording disk is disposed diagonally in the cleaning chamber. a first fitting means for fixing the recording disk to the washing tank; and a second fitting means for fixing the fixing means to the washing tank so that the fixing means can be freely fitted and removed when the recording disk is disposed obliquely in the rinsing chamber.
and a third fitting means for removably fixing the fixing means to the cleaning tank when the recording disk is placed horizontally, the first fitting means and the second fitting means is located below the third fitting means, and when the fixing means is fixed to the first fitting means and the second fitting means, approximately half of the recording disk is covered with the cleaning liquid or the rinsing liquid. When the recording disk is immersed in water and the fixing means is fixed to the second fitting means, the recording disk is positioned above the cleaning liquid level and the rinsing liquid.

The invention of claim (2) provides the ultrasonic recording disk cleaner of claim (1), in which the rotation driving means is driven at a low speed when a part of the recording disk is immersed in a cleaning liquid or a rinsing liquid. The present invention is characterized in that a rotating force variable means is provided for driving the recording disk at high speed when the recording disk is located above the surface of the cleaning liquid.

(Function) In the device according to claim (1), when cleaning the recording disk, the fixing means is fixed to the first fitting means. As a result, the recording disk is disposed obliquely in the cleaning chamber, and approximately half of the recording disk is located below the level of the cleaning liquid. Next, the rotation drive means and the ultrasonic generator are driven for a predetermined period of time. As a result, the recording disk is cleaned while rotating.

When this cleaning step is completed, the fixing means is removed from the first fitting means and fixed to the second fitting means.
As a result, the recording disk is disposed obliquely in the rinsing chamber, and approximately half of the recording disk is located below the level of the rinsing liquid. Next, the rotation drive means and the ultrasonic generator are driven for a predetermined period of time. As a result, the rinsing process is performed while the recording disk rotates.

When this rinsing step is completed, the fixing means is fixed to the third fitting means. As a result, the recording disk is placed horizontally above the cleaning liquid level and the rinsing liquid level. Thereafter, the rotation drive means is driven for a predetermined period of time. As a result, the recording disk rotates, and the cleaning liquid and rinsing liquid adhering to the recording disk are scattered by the centrifugal force and are dried in a short time.

According to the invention of claim (2), the rotational force variable means drives the rotational drive means at low speed during the washing step and the rinsing step, and drives the rotational drive means at high speed during the drying step.

During the cleaning and rinsing processes, when the recording disk is rotated at high speed, a vortex is generated in the cleaning liquid and rinsing liquid in the cleaning tank, and the cleaning liquid and rinsing liquid are scattered in the circumferential direction, so that the cleaning liquid and rinsing liquid spread over the entire recording disk. The liquid will not be able to spread. To prevent this from happening, the recording disk is rotated at low speed during the cleaning and rinsing steps.

On the other hand, during the drying process, the recording disk is rotated at high speed. This increases the centrifugal force and further shortens the drying process.
