Abstract: An image reading method according to the present invention involves causing an image sensor for reading an image of a document to move from a side at which the document is placed toward a home position of the image sensor, causing to reverse a movement direction at a turn-back position after the image sensor has passed the home position, and causing the image sensor to move to the home position again.
