Claim:
A scanning apparatus, for scanning a document, comprising: a housing, having a slit formed on a top surface thereof, the housing having two reflecting plates respectively extending on two opposite edges of the slit and facing the slit; two light emitting elements respectively disposed on the corresponding edges of the pair of reflecting plates and respectively emitting a scanning light onto each reflecting plate, each light emitting element including: a substrate, disposed in the housing and fixed on an opposite edge of a respective reflecting plate, wherein the substrate faces the respective reflecting plate and has an angle with respect to the respective reflecting plate; and a plurality of point light sources, disposed on the substrate, wherein each point light source emits a scanning light onto the respective reflecting plate, thereby projecting the scanning light reflected from the respective reflecting plate onto the document through the slit, and then the scanning light is reflected from the document to form an image light that enters the housing through the slit; and an image sensor, disposed in the housing for receiving the image light reflected from the document and converting the image light into image data.
