摘要： To prevent deformation of a chassis due to an impact force in an optical disc apparatus, there is provided a tray for inserting/ejecting an optical disc into/from an apparatus body, with the chassis connected thereto through vibration proof materials in plural portions in a surface opposite a disc placing surface. The tray has projecting portions projecting in a chassis direction in positions facing the chassis in peripheral portions of the plural connecting portions. The projecting portion is located at a position higher than a tray plane with which the vibration proof material comes into contact, and lower than the surface of a chassis facing the tray. When the vibration proof material is compressed and deformed due to the impact force, the projecting portion comes into contact with the chassis facing surface, to reduce the amount of deformation of the vibration proof material and thereby prevent deformation of the chassis.

摘要： In a prior art slim-type high speed rotation optical disk apparatus, the side wall of the bottom chassis is bent at a bending point toward the side of the optical disk according to the configuration of the corner air window section of the chassis. According to the present invention, this bent side wall is formed so as to have a first vertical wall which is adjacent to the bending point and a second vertical wall which is adjacent to and lower than the first vertical wall. This constitutes an L-shaped vertical wall in the air window section of the bottom chassis, resulting in reduced noise.
