Abstract: A linear light source module comprises a holder, a first light guide, a second light guide, a first light-emitting element and a second light-emitting element. The first and second light guides are mounted on the holder and arranged in series, where the first light guide has a first emitting surface and the second light guide has a second emitting surface. The holder partially surrounds the first and second light guides. The first light-emitting element is disposed close to a first end of the first light guide, and a light beam emitted by the first light-emitting element is reflected and converted by the first light guide into first linear light emitted from the first emitting surface. The second light-emitting element is disposed close to a first end of the second light guide, and a light beam emitted by the second light-emitting element is reflected and converted by the second light guide into second linear light emitted from the second emitting surface. An optical assembly for a scanner using such linear light source module is also disclosed.

Abstract: A scanning device comprises a light source, a reflecting mirror and a photosensor. The light source provides light to an original. A first portion of the light penetrates through a hole of the original and becomes penetrating light. A second portion of the light is reflected by a hole-free portion of the original and becomes second reflected light. The reflecting mirror reflects the penetrating light and generates first reflected light. The photosensor receives the first reflected light and the second reflected light and generates a hole-containing image signal representative of an image of the original.
