Abstract
Then image reading device includes a transparent document table, a frame, a reading unit, a moving mechanism, a white reference member, and a controller. The frame is provided around a peripheral of the document table. The white reference member is provided on the frame adjacent to the document table in the sub scanning direction and has a length in the main scanning direction longer than the document table. The reading unit includes a first reading part which reads an area corresponding to the document table and a second reading part which reads an area corresponding to the frame. The controller detects a boundary between the frame and the reference member based on a read value of the second reading part while moving the reading unit by the moving mechanism, and positions the reading unit at a home position apart from the boundary by a predetermined distance.
