Objective lens driving mechanism in optical storage device

An optical driving device, comprising:

• an objective lens for focusing a light beam onto an object;
• a lens holder having said objective lens;
• a platelike conductive elastic support member having one end for supporting said lens holder and the other end having a first terminal portion;
• a fixing member for fixing said other end of said platelike conductive elastic support member, said first terminal portion extendable past said fixing member in a direction opposite to said one end;
• a coil electrically connected to said platelike conductive elastic support member and fixed to said lens holder;
• and
• a flexible printed circuit board connected to said first terminal portion of said platelike conductive elastic support member,
• wherein said first terminal portion of said platelike conductive elastic support member is provided at a position facing a land of said flexible printed circuit board at right angles to said land,
• wherein said platelike conductive elastic support member further has a second terminal portion connected to said coil,
• wherein said first terminal portion extends in a longitudinal direction of said platelike conductive elastic support member, and
• wherein said platelike conductive elastic support member comprises a pair of first and second conductive leaf springs provided above and below said lens holder, each of said first and second conductive leaf springs having one end for supporting said lens holder and the other end having a first terminal portion, said first terminal portions of said first and second conductive leaf springs being positioned in symmetry with respect to a longitudinally extending center line of said first or second conductive leaf spring.

An optical storage device capable of at least reading information recorded on an optical storage medium, comprising:

• a carriage adapted to be reciprocated in a given direction of said optical storage medium;
• a driving unit reciprocating said carriage in said given direction;
• an objective lens for focusing a light beam output from a light source onto said optical storage medium;
• a lens holder having said objective lens;
• a platelike conductive elastic support member having one end for supporting said lens holder and the other end having a first terminal portion;
• a fixing member mounted on said carriage for fixing said other end of said platelike conductive elastic support member, said first terminal portion extendable past said fixing member in a direction opposite to said one end;
• a coil electrically connected to said platelike conductive elastic support member and fixed to said lens holder;
• and
• a flexible printed circuit board connected to said first terminal portion of said platelike conductive elastic support member,
