Abstract
An image reading device includes a document tray on which documents having different sizes are stacked; a document transport mechanism that sequentially feeds and transports the documents one-by-one; an image data generator extending in a width direction that intersects a document moving direction and having an image reading sensor that repeatedly reads, in the width direction, an image from each document, the image data generator generating image data expressing an image within a target reading region of a currently fed document by permitting the image reading sensor to perform a reading process to a region protruding from the target reading region so as to cause the image reading sensor to perform the reading process over a reading region that does not cause unread parts within the target reading region; an image memory storing the image data; and an image extractor extracting the image data from the stored image data.
