ABSTRACT:
In a two-carrier type image scanner, a first carrier (10) is moved in parallel to a document surface at a scanning speed and a second carrier (20) is moved at half the scanning speed, the image scanner optically reading out image information such as figures and characters on the document surface using an optical system mounted on the two carriers. To permit the adjustment of the carrier in the roll direction to be easily conducted, one side of each of the carriers (10, 20) is movably engaged with a fixed guide shaft (46), and the other side is guided by a bearing (53) which rolls on a fixed guide rail (47) disposed in parallel with the guide shaft (46), wherein the carrier is capable of being adjusted in the roll direction with respect to the guide shall (46) when a position of the bearing (53) with respect to the carrier is adjusted.
