Abstract
A light-gathering structure for a scanning module is disclosed. The light-gathering structure for a scanning module having at least a scanning area, a lens and a light-sensing element includes at least an elliptic arc surface having a first focus; at least a circular arc surface having a circular center being superpositioned on the first focus; and at least a light source positioned at the first focus, wherein a light from the light source is reflected by the elliptic arc surface and the circular arc surface to the scanning area and converged on the light-sensing element through the lens.

A light-gathering structure for a scanning module having at least a scanning area, a lens and a light-sensing element, comprising:
- at least an elliptic arc surface having a first focus;
- at least a circular arc surface having a circular center being superpositioned on said first focus;
- and
- at least a light source positioned at said first focus,
- wherein a light from said light source is reflected by said elliptic arc surface and said circular arc surface to said scanning area and converged on said light-sensing element through said lens.
