Abstract

PURPOSE:To clean an objective lens manually by fitting a cleaner brush provided with a brush to a cartridge case capable of being loaded/ejected turnably to an optical disk device and extending the operation lever from the cartridge case externally. CONSTITUTION:In cleaning an objective lens of an optical disk device, a cleaning liquid such as alcohol is included to one face of a brush 9 of the cleaner brush 7 and the cleaning cartridge is loaded to a loading port so that the face is directed to the optical head side. When the cartridge is loaded to a prescribed position, an opening 3 comes to a position opposed to an objective lens of the optical head and the operating lever 10 is moved to the left/right for several number of times manually. Thus, the brush 9 is moved on the objective lens to clean the lens. Then the cartridge is turned over and loaded to the optical disk device again, it is moved by the operation lever and the dirt of the objective lens is wiped by a dry wiping at the rear side of the brush.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a cleaning cartridge used for cleaning an objective lens of an optical head of an optical disc device.

Conventional technology Conventionally, the objective lens of an optical disk device was used as a G! No special cleaning equipment had been developed, and when cleaning, the objective lens of the optical head was exposed by removing the housing cover of the optical disk device, and the objective lens was manually cleaned using cotton swabs, etc. .

Problems to be Solved by the Invention However, with this cleaning method, the housing cover, etc. must be disassembled each time cleaning is performed, and therefore only an expert with knowledge of the equipment can perform the cleaning, and it is time consuming. , there was a problem in that it required time and effort.

For cassette tapes, there is a so-called cleaning tape in which a special tape with cleaning ability is inserted into the cassette tape cartridge.This is installed in a device, the tape is brought into contact with a magnetic head, and the tape is run. The magnetic head is being cleaned. Based on this idea, it is conceivable to create a cleaning cartridge in an optical disc device by inserting a cleaning disc into a disc cartridge.

However, simply placing the cleaning disk in the cartridge poses a problem.

The big problem is that in the case of cassette tapes, the contact between the magnetic head and a part of the cleaner is not that complicated, but in the case of optical disk drives, positioning is complicated, and like cassette tapes, they are in constant contact. The condition is not suitable.

The present invention has been made in view of the above-mentioned problems, and it is possible to clean the objective lens of an optical disk device without disassembling a part of the device and without damaging the objective lens or the actuator that holds it. The purpose of the present invention is to provide a cleaning cartridge that can perform the following tasks.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention provides a cleaner brush in a cartridge case that is removable from an optical disc device and that has an opening on at least one side at a position facing the optical head of the optical disc device. The cleaner brush is rotatably mounted, and the cleaner brush is provided with a brush portion at the opening position and an operating lever extending from the cartridge case.

Function: The cleaning cartridge of the present invention can be installed in an optical disc device instead of a disc cartridge.
By manually moving the operating lever that extends outward from the camera to the left and right when the lens is attached, the brush portion can be moved to the open position and the objective lens can be cleaned. At this time, since the cleaner brush is operated by hand, it can be cleaned without damaging the objective lens or actuator.

Embodiment FIG. 1 is an external view showing a cleaning cartridge for cleaning an objective lens of an optical disk device according to an embodiment of the present invention.
FIG. 2 is a plan view showing the inside thereof, and FIG. 3 is a sectional view thereof. In the figure, 1 is a cartridge case;
It has the same external shape as a disk cartridge containing an optical disk, and is removable from an optical disk device. Car 1 - The IJ case 1 is provided with openings 2 and 3 on both sides thereof. The opening 2 is provided at a position into which the drive device of the optical disc device is inserted when the cartridge case l is attached to the optical disc device. Further, the opening 3 is provided at a position facing the optical head of the optical disc device. Furthermore, the cartridge case 1 is provided with an annular projection 4 surrounding the opening 2, a concentric arc-shaped projection 5 close to the annular projection 4, and an arc-shaped projection 6 arranged to sandwich the opening 3 on the inner surface. Reference numeral 7 denotes a cleaner brush 1 housed in the cartridge case 1, which, as shown in FIG. 4, consists of a central annular portion 8, a brush portion 9 connected to the annular portion 8, and an operating lever 10. The brush portion 9 has undefeated soft bristles, fibers, etc. planted on both sides thereof. As shown in FIGS. 2 and 3, the cleaner brush 7 is held rotatably by fitting its annular portion 8 between an annular projection 5 and an arcuate projection 6 on the inner surface of the cartridge case 1.

At this time, the brush portion 9 is in a position facing the opening 3, and its tip is supported by the arc-shaped projection 6. Further, the operating lever 10 extends outward from the cartridge case 1.

Next, a method of using the cleaning/cleaning cartridge having the above structure will be explained. Objective lens for optical disc device? iJ
h) When doing this, first, remove the brush part 9 of the cleaner brush 7.
One side of the cleaning cartridge is soaked in a cleaning liquid such as alcohol, and the cleaning cartridge is inserted into the disk insertion slot so that that side faces the optical head. When the cleaning cartridge is installed in a predetermined position, the opening 3 is in a position facing the objective lens of the optical head. In this state, move the operating lever 10 left and right several times by hand. Accordingly, as shown in FIG. 5, the brush portion 9 of the cleaner brush 7 moves over the objective lens 11 of the optical head, and the objective lens 11 is cleaned with the brush portion 9 impregnated with the cleaning liquid. Next, the cleaning cartridge is turned over and reinstalled into the optical disc device, and by manually moving the operating lever 10, the dirt on the objective lens is wiped off with the brush section 9 (for dry wiping) on the back side. As described above, the optical head can be cleaned well without removing any parts of the optical disc device.

In the above embodiment, a cleaning cartridge having brush portions on both sides is used, but a cleaning cartridge having brush portions on only one side may be used instead. However, in that case, it is preferable to prepare two pieces: one for applying the cleaning liquid and one for dry wiping.

Effects of the Invention As is clear from the above description, the present invention provides for a cleaner brush having a brush portion to be rotatably attached to a cartridge case that is removably attached to an optical disc device, and a lever for operating the cleaner brush to be mounted externally from the cartridge case. Since it is an extended cleaning cartridge, you can use this cleaning cartridge instead of a disk cartridge.
By attaching it to an optical disc device and moving the operating lever left and right by hand, the objective lens can be cleaned with the brush part, eliminating the need for disassembly of the optical disc device housing cover, etc., making it easy to clean the optical disc device. This has the effect that the objective lens can be adjusted manually.
