The optical scanner unit moves to a scanning range of the for-moving-document contact glass and scans the document in a static manner when the document is conveyed in an automatic manner, and the optical scanner unit includes a contact image sensor, a carriage that holds the contact image sensor in a movable manner in the sub-scanning direction, and a pair of end sliders arranged on both ends of a plane facing the reading face in a longer-side direction of the optical scanner unit.
