本発明は光又は光磁気ディスク記録再生装置の防塵機構
と防振機構に関する。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a dust-proof mechanism and a vibration-proof mechanism for an optical or magneto-optical disk recording/reproducing device.

しゃ断し読取り不良の原因となる。An optical or magneto-optical disk recording and reproducing device is a device that records and reproduces high-density information on a disk, which is a recording medium, and is characterized by a large capacity and the ability to easily replace the recording medium. However, on the other hand, dust and air enter through minute gaps in the device and accumulate on the surface of the objective lens provided in the optical head. Therefore, the laser light reflected and condensed by the lens is cut off, causing reading errors.

ッドから照射される光ビームが前記凹凸の記録溝からは
ずれ読取不良をおこすことがある。Furthermore, in this device, the optical head reads the unevenness of several microns on the disk without contacting the disk, so when the driver of the optical head vibrates due to external vibration, for example, the light beam irradiated from the optical head records the unevenness. It may fall out of the groove and cause reading errors.

4号公報等が挙げられる。As a method for dealing with these phenomena, there is a method in which the disk insertion/ejection mechanism section and the mechanical unit for driving the optical head are supported by an elastic body or a viscoelastic body from the chassis section of the apparatus. As an example of this type of device, for example, Utility Model Application No. 63-18449
Publication No. 4 etc. can be mentioned.

支持するようにするものである。In order to achieve the above objective, the optical head movement, transport mechanism section, disk motor, and mechanism for inserting and ejecting the disk (hereinafter collectively referred to as the mechanism section) were constructed using quinoid-cured rubber. The device is equipped with a cylindrical rubber supported by a spring and subjected to quinoid vulcanization, so that when the device is placed vertically, the gravitational force of the mechanism is supported by the cylindrical rubber.

いので内部の金属を腐食させない。The head drive mechanism section 2 including the optical head is sealed in the case 6 together with other mechanism sections except when a disk is inserted or ejected, so that it can be dust-proof. Further, since the rubbers 4 and 5 are subjected to quinoid vulcanization or secondary vulcanization, no gas containing sulfur is generated, so that the metal inside is not corroded.
