ABSTRACT:
A scanner is provided which can read information of the whole face of a transmission type reading object by using only a linear-illumination light source for illuminating a reflection type reading object. The scanner has: conveying mechanisms which convey the reflection type reading object and the transmission type reading object between a body case and a cover case in a predetermined direction; an illumination system which is disposed in the body case, which emits the illumination light toward the reflection type reading object, and which forms a linear illuminated portion on the reflection type reading object, the linear illuminated portion linearly elongating in a direction perpendicular to the conveying direction; an illumination light guide plate which is disposed in the cover case, and which guides the illumination light to form a linear illuminated portion on the transmission type reading object; and an image receiving system which is disposed in the body case, and which receives images of the linear illuminated portions of the read objects.
