Image reading apparatus with transport device control

An image reading apparatus comprising:

• an apparatus body;
• a transport device that is openable and closable relative to the apparatus body, the transport device transporting a document to a predetermined position of the apparatus body when the transport device is closed relative to the apparatus body;
• an image reading unit disposed in one of the apparatus body and the transport device, the image reading unit reading an image of the document transported by the transport device;
• a reference member that is disposed in the other of the apparatus body and the transport device, the reference member being disposed at a position opposite the image reading unit when the transport device is closed, the reference member being read by the image reading unit;
• and
• a control unit that causes the image reading unit to read the reference member in a first reading condition and a second reading condition at a predetermined time, and if the transport device is closed at the predetermined time, causes the image reading unit to read the reference member before the transport device starts transporting the document, and if the transport device is open at the predetermined time, causes the image reading unit to read the reference member in the first reading condition after the transport device starts transporting the document and an image of the document is read by the image reading unit in the first reading condition, and causes the image reading unit to read the reference member in the second reading condition after the transport device starts transporting the document and the document has passed through the image reading unit and reading of the image of the document has been finished.

An image reading apparatus comprising:

• a scanner;
• a document feeder that is openable and closable relative to the scanner, the document feeder transporting a document to a position of the scanner when the document feeder is closed relative to the scanner;
• an image reading unit disposed in one of the scanner and the document feeder, the image reading unit reading an image of the document transported by the document feeder;
• a white reference tape that is disposed in the other of the scanner and the document feeder, the white reference tape being disposed at a position opposite the image reading unit when the document feeder is closed;
• and
• a control unit that causes the image reading unit to determine whether the document feeder is open with respect to the scanner, and when it is determined that the document feeder is closed, the control unit controls the image reading unit to read the white reference tape before the document feeder starts transporting the document, and when it is determined that the document feeder is open, the control unit causes the image reading unit to read the white reference tape after the document feeder starts transporting of the document.
