Abstract:
1. A disk apparatus comprising a chassis outer sheath having a base body and a lid, having a convex portion, that is in parallel with said base body, in which a front surface of said chassis outer sheath is formed with a disk inserting opening into which a disk is directly inserted, the base body is provided with a traverse, a spindle motor having a rotation stage on which the disk is placed is held by the traverse, one side of the traverse is inclined and moved around another side of the traverse as a rotation support shaft on the front side of the chassis outer sheath, thereby bringing the rotation stage close to the lid, the disk placed on the rotation stage is pushed toward the rotation stage to mount the disk on the rotation stage by the convex portion being smaller than the rotation stage and being provided around a circular opening greater than a hub of the spindle motor on the side of the center portion of the lid such that the convex portion projects toward the rotation stage at a position opposed to the rotation stage, wherein the convex portion located on the one end of the traverse is higher than the convex portion located on the other end of the traverse, whereby a tip end of the convex portion is inclined such that the tip end of the convex portion becomes substantially in parallel to a surface of the rotation stage when the traverse approaches the lid.
