Device for supporting an optical disc driving device

Abstract

A main frame is supported in a box, by first elastic members. An optical disc driving device is mounted on the main frame. A sub-frame is supported on the main frame by second elastic members.

What is claimed is  
     
         1 . A supporting mechanism for an optical disc driving device, comprising: 
 a box;    a main frame provided in the box;    first elastic members elastically connecting the main frame to the box;    an optical disc driving device mounted on the main frame, the optical disc driving device including a spindle motor and a turntable securely mounted on a rotating shaft of the spindle motor;    a sub-frame; and    second elastic members elastically connecting the sub-frame to the main frame.    
     
     
         2 . The mechanism according to  claim 1  wherein the mass of the sub-frame is 1/10-1/3 of the mass of the main frame.  
     
     
         3 . The mechanism according to  claim 1  wherein the sub-frame has a shape of a flat plate.  
     
     
         4 . The mechanism according to  claim 1  wherein the sub-frame is made of metal.  
     
     
         5 . The mechanism according to  claim 1  wherein the second elastic member is made of either of rubber and plastic.
