Assignee: TDK TAIWAN CORP.
Field: Optics (Instruments)
Classification: CPC G  H | IPC G  H

Claim 0:
1. An optical mechanism, comprising:
a movable module, for connecting an optical element, and comprising a holder, wherein the holder comprises:
a hollow main body, having a connection surface; and
a restricting portion, having an upper surface and protruding outward from the main body in a horizontal direction perpendicular to an optical axis of the optical element;

a fixed module, wherein the movable module moves relative to the fixed module within a moving range;
a driving assembly, having a coil and a magnet for driving the movable module to move relative to the fixed module, wherein the restricting portion restricts the coil in a predetermined position on the holder;
a first resilient element, having a first connecting portion, a second connecting portion, and a deformable portion connecting the first connecting portion with the second connecting portion, wherein the first and second connecting portions respectively connect to the fixed module and the connection surface of the main body, and the upper surface faces the deformable portion; and
a second resilient element having a third connecting portion and a fourth connecting portion respectively connected to the fixed module and the holder, wherein the magnet has a first height along the optical axis, a first distance is formed between the second and fourth connecting portions along the optical axis, and the first height is greater than the first distance;
wherein when the movable module is located at any position within the moving range, the upper surface and the first resilient element are spaced apart from each other and at least partially overlap along the optical axis.
