Abstract

PURPOSE:To enable dust sticking to an optical disk to be removed by providing a second pore to optical disk cartridge and disposing a brush between the inside of the cartridge facing the position of that pore and the optical disk. CONSTITUTION:The second port 5 is provided to the optical disk cartridge 1, a brush supporting member 6 to which the brush 7 wiping the surface of the optical disk 2 is fitted is incorporated between the optical disk 2 and the inside of the cartridge 1 by being faced to the pore 5 and the supporting member 6 is fixed to the inside of the cartridge 1 through a flat spring 8 and the like. Then, when the cartridge 1 is loaded to a main body device, a driving pin provided to the device side is inserted from the pore 5, the supporting member 6 is pushed up and the brush 7 is pressed and contacted to the disk 2. Thus, by the rotation of the disk, the dust sticking to the surface can be wiped and removed.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a disc cartridge for recording information, and more particularly to the structure of a cartridge that accommodates an optical disc medium used in an optical disc device.

[Conventional technology]

Conventional optical disk cartridges are equipped with a shutter mechanism in which the central part for clamping the optical disk when loaded into the main unit and the part where the head approaches the optical disk open and close when the optical disk cartridge is removed from the main unit. , except for the shutter mechanism, which has a nearly sealed structure.

[Problem to be solved by the invention]

According to the above-described conventional optical disk cartridge, since the shutter is open when it is loaded into the main unit, surrounding dust adheres to the optical disk, which adversely affects recording and reproduction on the optical disk. Furthermore, it has been impossible to provide a dust removal mechanism on the main unit side to remove dust adhering to the optical disk because the shutter portion of the cartridge is conventionally used exclusively for head access.

SUMMARY OF THE INVENTION An object of the present invention is to provide an optical disc cartridge recycler which solves the above problems by providing a brush on the cartridge side.

[Means to solve the problem]

To achieve the above object, the present invention provides a semi-sealed cartridge having a shutter mechanism that opens the center of the optical disk and the area where the head is close to the optical disk when the cartridge is loaded into the main device, and closes when the cartridge is taken out from the main device. , a second hole for accessing the inside of the cartridge is opened, and the main body is always biased toward the inner surface of the cartridge by a leaf spring or the like, and is placed in the gap between the inner surface of the cartridge and the optical disk so as to face the second hole. A built-in brush is brought into contact with the optical disc by a pin or the like that is pushed through the second hole from the main unit side when the disc is loaded into the apparatus.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is an overall external view of an optical disk cartridge according to an embodiment of the present invention.

In the figure, an optical disk cartridge 1 that stores an optical disk 2 is equipped with a shutter mechanism 3, and when loaded into the main unit, this opens and the optical disk 2 is clamped at the opening of the head and clamper access hole 4, allowing access to the head. It has a structure. Since the cartridge 1 has a nearly sealed structure except for the shutter mechanism 3, the entire structure is juxtaposed and closed. However, in the present invention, a second hole 5 is provided in the optical disk cartridge 1, and as shown in FIG. ,
A brush support member 6 equipped with a brush 7 for wiping the surface of the optical disc 2 is built into the gap between the optical disc 2 and the inside of the cartridge 1 facing the hole 5, and the support member 6 is supported via a leaf spring 8 or the like. It is fixed to the inner surface of the cartridge 1. As shown in FIG. 2, the brush support member 6 is normally pressed against the inside of the cartridge 1 under spring pressure, and is held so that the brush 7 does not come into contact with the optical disc 2. However, when the optical disk cartridge 1 is loaded into the main device, the drive pin 10 provided on the device side fits into the second hole 5 and pushes down the brush support member 6, as shown in FIG. The dust attached to the surface is wiped off by the rotation of the pressure contact.

〔Effect of the invention〕

As explained above, according to the present invention, since the second hole is provided in the optical disk cartridge and the brush is installed in the gap between the inside of the cartridge and the optical disk facing the second hole, when the cartridge is loaded into the main unit, By simply pushing a pin or the like on the main unit side into the second hole of the cartridge, the brush can be brought into contact with the optical disc and dust adhering to the optical disc can be effectively removed. In addition, a few seconds is sufficient for the contact time, and there are almost no abrasion marks caused by the brush on the surface of the optical disc.
