ABSTRACT:
The invention discloses an improved structure of light-source module, which arranges a reflection piece of light-source module in an image picking-up device of optical scanner. The invention applies the design of improved reflection piece to generate a compensatory function to the light source to reduce the waste formed by the light dissipation, which will be gathered by the reflection piece and be reflected to the document to be scanned. With the design of appropriate angle and position, the reflection piece may completely reflect the light onto the document to be scanned for obtaining a preferable quality of scanned image. Wherein, the reflection piece may be designed as two pieces, one of which may reach the function of light compensation, or one reflection piece may be designed as two reflection parts, one of which may reach the function of light compensation.
