Abstract

An image reading device includes a target detection unit (81), a maximum size setting unit (301), a reading area setting unit (302), and an image reading unit (303). The target detection unit (81) detects a leading edge of an object of multiple objects conveyed in a conveyance direction. The maximum size setting unit (301) sets a maximum size of the multiple objects including a maximum width and a maximum length. The reading area setting unit (302) determines and sets an entire reading length of a reading area in the object in the conveyance direction in accordance with the maximum size; and determines and sets an extended reading length of an extended portion of the object in the conveyance direction, the extended portion being disposed downstream of the leading edge of the object, detected by the target detection unit (81), in the conveyance direction. The image reading unit (303) starts reading, an image on the extended portion in the object, at an extended position downstream of the leading edge by the extended reading length in the conveyance direction; and terminates reading the image on the object when a reading length that has been read reaches the entire reading length of the reading area.
