Abstract
A scan device includes a main body, a transparent glass plate, a carrier, a light source, a reflecting unit, a lens and an image sensor. Light is emitted from the light source through the transparent glass plate to a document. Then, the light is reflected by the document and passes through the transparent glass plate to reach the reflecting unit. The light is reflected by the first mirror to travel to the second mirror and the third mirror and reflected by the second and third mirrors for several times, then reaches the fourth mirror and fifth mirror to passes through the lens, and forms an image on the image sensor.
