Vibration preventing device and an optical disc drive having the same

摘要

An optical disc drive has an improved vibration preventing device. A main chassis has opposite sidewalls and first and second mold tension parts integrally formed with the sidewalls, respectively. A pickup deck has a turn table adapted to receive a disc and a pickup moving in a radial direction of the disc and mounted to the main chassis to move up and down. A sub chassis has first and second mold tension guide parts mounted on a front of the pickup deck and supported by and under the first and the second mold tension parts. A disc tray moves inwardly and outwardly with respect to the main chassis. The mold tension guide parts of the sub chassis are elastically supported by the mold tension parts of the main chassis in an up-position of the pickup deck, thereby absorbing external impacts and inner vibrations.
