Abstract
The optical system of a scanner comprising at least four reflecting mirrors, a focusing lens and an image sensor has its lens placed outside the area encircled by the reflecting mirrors so that the reflecting mirrors can be placed closer in the vertical direction. Thus, the vertical dimension of the scanner is made smaller.
