Claim:
1. An image reading apparatus, comprising: a display; an operation circuit; a storage; a platen; a scanner beneath the platen; a document placement table; a size detection sensor beneath the document placement table; a document conveying unit for conveying onto the platen a document placed on the document placement table; wherein control circuitry configured as in the first mode, the read size determination circuit establishes the size of a document detected by the first-mode document reading arrangement as a first read size, and establishes a read size of a document set in advance by the initial size setting circuit as a second read size, the first read size being the read size of a document when the first-mode document reading arrangement reads the document, the second read size being the read size of a document when the second-mode document reading arrangement reads the document, and in the second mode, the read size determination circuit establishes the size of a document detected by the first-mode document reading arrangement as the first read size, and if the second-mode document reading arrangement reads the document, the control circuitry displays on the display a setting screen for the read size of the document, and establishes the read size of the document set in the setting screen as the second read size when a start instruction for a document reading job is entered through the operation circuit.
