  • Patent number: 7019873
    Abstract: An image reading apparatus has a reading mode to read an image on a still document, and a reading mode to read an image on a moving document, and includes a first reading device to read one surface of the still document at a first reading station and a document moving at a second reading station, and a second reading device for reading the other surface of the document moving at a third reading station. The first, second and third reading stations are arranged adjacent to each other along the document transfer direction. A compact and light weight system capable of stable transport of the document and of quality image reading is thereby attained.
    Type: Grant

  • Patent number: 6995880
    Abstract: An image reading apparatus for reading both surfaces of a document has a first reading device and a second reading device disposed at a side opposite to the first reading device to sandwich a reading station for reading the document, thereby simultaneously reading both surfaces of the document transported to the reading station. The reading station includes a first path to guide the document to be read by the first reading device and a second path for guiding the document to be read by the second reading device. A gap in the second path is narrower than a gap in the first path. This structure does not cause document transport problems and attains quality readings of both surfaces of the document while having different optical reading means.
