2. Description of the Related Art Conventionally, as for cleaning of an optical disc apparatus, an optical disc apparatus automatically cleans the lens by detecting dirt on the lens of the optical lens, or an optical disc apparatus linked with a read / write processing operation of the optical disc apparatus. In some cases, the medium and the head are automatically cleaned.

As the above-mentioned conventional optical disk device, there is, for example, an optical disk device described in JP-A-6-267096. This apparatus cleans the lens surface generated during recording / reproduction of an optical disk medium without interrupting the operation, and enables the operation to be continued.

The information recording medium cleaning device described in Japanese Patent Application Laid-Open No. 6-11153 is a cleaning device that applies an appropriate tension to a cleaning cloth and constantly sends the cleaning cloth stably.

Further, in the optical disc apparatus disclosed in Japanese Utility Model Laid-Open No. 4-115323, there is described a technique for automatically and continuously cleaning dust adhering to a head and an optical disc medium surface, thereby eliminating the need for manual cleaning. .

FIG. 11 is a perspective view showing the structure of an example of a conventional optical disk apparatus having an optical head / medium cleaning function. This apparatus includes an optical disk medium 32, a cartridge 33, a load mechanism 34, a spindle motor 35, an optical head 36, a carriage mechanism 37, and a cleaning mechanism 3.
8, control unit 39, lens 40, drive source 41, brush 42,
It comprises a brush 43, a shaft 44, a motor 45, and a mounting plate 46. During recording and reproduction, when the control unit 39 confirms that the error rate of the reproduction signal due to the dirt on the surface of the lens 40 is reduced, the optical head 36 is lowered by the driving of the driving source 41 and retracted. 37 is moved to the position of the cleaning mechanism 38. Then, the brush 43 starts rotating by the rotation drive of the motor 45, and the optical head 36 is driven by the drive source 41.
Is raised for a certain period of time, and the surface of the lens 40 is cleaned with the brush 42. When the cleaning is completed, the optical head 36 is lowered again, and then the rotation of the motor 45 is stopped. Further, when the carriage mechanism 37 moves to the original position again and the optical head 36 is raised,
