Abstract

PURPOSE:To eliminate dirt of an optical head simply by providing a mechanism delivering a torque of a spindle of the device to a shaft mounted with a brush while converting it into a right angle direction into a case. CONSTITUTION:An iron piece 13 engaging with a spindle hub of the device is provided and a rotary plate 2 is turned by being gripped with the spindle by the magnet clamp system and converted into the drive of the shaft 11 supporting a roller 9 with the roller 9 in contact at a right angle with the upper face of the rotary plate 2. A cylindrical brush 6 is loaded to the shaft 11 and the brush 6 is in contact with the optical head to clean the dirt. Then the rotary plate 2 and the brush 6 are supported by a support mechanism 3 and accommodated freely turnably in the case 1 with bearings 5, 7 supporting both ends of the rotary shaft 4. Thus, the optical head is simply cleaned.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an optical head cleaning cartridge for cleaning an optical head of an optical disc device.

[Conventional technology]

Conventional optical disk devices and optical disk cartridges are not equipped with a cleaning means for cleaning the optical head of an optical disk device, so the optical head is cleaned manually using a tool such as a cotton swab.

[Problem to be solved by the invention]

As mentioned above, the conventional method for cleaning the optical head of an optical disk device requires disassembling the optical disk device to expose the optical head and cleaning it manually, which is a laborious and time-consuming process. It has the disadvantage of being necessary.

[Means to solve the problem]

The optical head cleaning cartridge of the present invention includes a rotating plate that engages with the spindle of the optical disk device to rotate, and a rotating plate that rotates in contact with the upper surface of the rotating plate to change the direction of the rotational axis to a right angle direction. a roller; a cylindrical brush attached to the rotating shaft of the roller;
A support mechanism that rotatably supports the rotary plate and the roller, a case that accommodates and rotatably supports the support mechanism, and a spring mounted between the support mechanism and the case. There is.

〔Example〕

Next, embodiments of the present invention will be described with reference to the drawings.

Fig. 1 is a perspective view showing an embodiment of the present invention, Fig. 2(a)
and (b) are a plan view and a sectional view taken along the line A--A of the embodiment shown in FIG.

As shown in FIGS. 1 and 2, the optical head cleaning cartridge (cartridge) 1 has an iron piece 13 that engages with a spindle hub of the optical disk device (device) when it is installed in the device. The rotating plate 2, which rotates in synchronization with the spindle of the device, is rotated by being gripped by the spindle using a magnetic clamp method.

The rotation of the rotary plate 2 is translated into rotation of the shaft 11 supporting the roller 9 by means of the roller 9, which is in contact at right angles to the upper surface of the rotary plate. The axis 11 and the axis 12 of the rotary plate 2 are perpendicular to each other.

A cylindrical brush 6 is attached to the shaft 11 to which the rotation of the spindle is transmitted in this way, and this brush 6
A zero-rotation plate 2 and a brush 6, which come into contact with the optical head to clean dirt from it, are supported by a support mechanism 3 and rotatably housed in a case 1 by bearings 5 and 7 that support both ends of a rotation shaft 4. has been done. The support mechanism 3 is
Before the case 1 is attached to the apparatus, it is held by the spring 10 and is in the position shown in FIG. 3A, and the brush 6 is stored in the case 1. When the case 1 is installed in the device, the rotary plate 2 is gripped by the spindle of the device, which lowers the support mechanism 3 into the position shown at the mouth in FIG. Contact with optical head.

〔Effect of the invention〕

As explained above, the optical head cleaning cartridge of the present invention converts the rotational force of the spindle of the device into the right angle direction and transmits it to the shaft on which the brush is attached. By providing the mechanism inside the case, there is an effect that dirt on the optical head can be easily removed simply by installing the cartridge in the apparatus.
