Abstract
An image reader is provided with a transparent member which is placed in an optical path from the surface of an original document bed on the side of a carriage to a condensing lens, whereby when the transparent member exists at a predetermined position, the condensing lens can be focused on a translucent original existing at a position above the position of a reflection original. When the transparent member is at a second predetermined position, the condensing lens can be focused on the reflection original. The condensing lens can be focused on more than one position simply by placing the transparent member in the optical path, so that the structure is simple and the manufacturing costs can be reduced.
