Disc drive
First Claim
1. An optical disc drive for playing back or playing back and recording an optical disc, the disc drive comprising:
- a main body which includes a mechanism unit having a disc rotating means for rotating the optical disc and a play back means for at least playing back information recorded on the optical disc, the main body having side portions;
a casing for housing the main body, the casing including a side plate and a top plate which is removably fixed to the side plate, said side plate having side walls which partially surround the side portions of the main body, each side wall of the side plate having an upper edge, said side plate and said top plate being formed of a metal plate;
a plurality of protrusions integrally formed on the upper edges of the side walls of the side plate so that the top plate is in contact with the side plate through the protrusions to establish point contact between the side plate and the top plate; and
means for fastening the top plate to the side plate.

Abstract
A disc drive is constructed from a main body which includes a mechanism unit having a disc rotating mechanism for rotating a disc and a play back mechanism for playing back information recorded on the disc, disc tray movably provided with respect to the main body for supporting a disc and a casing for housing the main body. The disc drive is provided with vibration absorbing members for suppressing transmission of vibration caused by high speed rotation of the disc from the main body to the casing. The vibration absorbing members are formed of elastical members and they are arranged between the side portions of the main body and the inside of the casing, thereby the main body is supported by the casing through the vibration absorbing members to prevent vibrations caused in the main body from being transmitted to the casing. Further, the casing has a U-shaped side plate and a top plate fixed to the side plate by screws, in which the top plate is in point contact with the side plate through a plurality of protrusions formed on upper edges of the side plate. This point contact between the top plate and the side plate makes it possible to prevent rattling from being caused by the transmitted vibrations, thereby preventing generation of noise.

15. An optical disc drive for playing back or playing back and recording an optical disc, the disc drive comprising:
-
a main body which includes a mechanism unit having an optical disc rotating means for rotating the optical disc and a play back means for at least playing back information recorded on the optical disc, the main body having side portions; a casing for housing the main body, the casing including a side plate and a top plate which is removably fixed to the side plate, said side plate having side walls which partially surround the side portions of the main body, said side walls including first and second side walls which face each other through the main body and a third side wall which joins the first and second side walls wherein each of the side walls of the side plate has an upper edge and wherein said side plate and said top plate being formed of a metal plate; at least two protrusions integrally formed at least on the upper edges of the first and second side walls of the side plate so that the top plate is in contact with the side plate through the protrusions to establish point contact between the side plate and the top plate; and means for fastening the top plate to the side plate, said fastening means including mounting portions provided at least between the protrusions formed on the first side wall and between the protrusions formed on the second side wall, respectively, for screw fastening the top plate to the side plate.
