本発明は光ヘッド駆動装置に関し、特にキャリッジの走
行範囲内での光ヘッドの経時的傾き変化量を改良した光
ヘッド駆動装置に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an optical head drive device, and more particularly to an optical head drive device that improves the amount of change in inclination of an optical head over time within the travel range of a carriage.
従来、この種の光ヘッド駆動装置は、通常大気雰囲気環
境条件下で使用されキャリッジの転がり軸受はレイル面
との間で摺動可能な構造となっていた。Conventionally, this type of optical head driving device was normally used under atmospheric conditions, and the rolling bearing of the carriage was structured to be able to slide between it and the rail surface.
上述した従来の光ヘッド駆動装置は、キャリッジの転が

て大きく悪化し、キャリッジに固定されてい、る光ヘッ
ドの傾きが大きくなり、光ヘッド駆動装置の信頼性が低
いという欠点があった。The above-mentioned conventional optical head drive device does not have a mechanism to clean the sliding surface between the rolling bearing of the carriage and the rail surface, so dust in the atmosphere accumulates on the rail surface over time, causing the carriage to roll. Dust adheres to the running surface of the bearing rail, causing the carriage's running posture to deteriorate significantly compared to its initial state, and the optical head fixed to the carriage to tilt significantly, reducing the reliability of the optical head drive device. It had the disadvantage of being low.

材を設けたことを特徴としている。An optical head drive device of the present invention includes a carriage for holding and fixing an optical head, a rolling bearing attached and fixed to the carriage, and a rail for supporting the rolling bearing. It is characterized by having the following.
次に、本発明の一実施例について図面を参照して説明す

ル６でキャリッジ２を安定に支持する構成としている。1 and 2, the optical head driving device of the present invention mounts and fixes the RAD 1 on a carriage 2,
The carriage 2 is stably supported by six rolling bearings 4 attached to the carriage 2 by a main rail 3, a fixed trail 5, and a preload rail 6.

除嵐部材８がなぞり除塵する構造となっている。The carriage 2 and the optical head mounted on the carriage 2 are connected to a coil (not shown) attached to the carriage 2 and a magnetic circuit (not shown) disposed on the pace plate 7.
(not shown), the rolling bearing 4 rolls on the main rail 3, preload rail 6, and fixed trail 5, and operates stably and freely in the front-back direction. The carriage 2 is provided with a dust removal member 8 before and after a rolling bearing 4a provided at a location where it slides on the main rail 3. It has a structure that removes dust by tracing.

傾きが大きくなるという玩象が無くなり、光ヘッド駆動
装置の信頼性が高くなるという効果がある。As explained above, the present invention has a simple configuration in which dust removal members are provided before and after the carriage, so that when the optical head drive device is used under general environmental conditions, dust accumulates on the rail surface over time. There is an effect that the reliability of the optical head drive device is improved because the problem of the carriage running in a bad position and the optical head mounted and fixed on the optical head becoming tilted greatly is eliminated.
