Patent ID: 8749856

Claim:
An image reading device comprising: a document holding surface configured to hold a first document for flatbed scanning; a document conveyor unit configured to convey a second document along a conveying path for ADF-type image scanning; a first document contact surface configured to come into contact with a first side of the second document when the document conveyor unit conveys the second document; a first document pressing member disposed above the first document contact surface and configured to press the second document toward the first document contact surface when the document conveyor unit conveys the second document; a second document contact surface configured to come into contact with a second side of the second document when the document conveyor unit conveys the second document; a second document pressing member disposed below the second document contact surface and configured to press the second document toward the second document contact surface when the document conveyor unit conveys the second document; a first reading unit configured to: read an image on a side of the first document held by the document holding surface while traversing below the document holding surface; and read an image on the first side of the second document being conveyed by the document conveyor unit while the first reading unit is stationary below the first document contact surface; and a second reading unit disposed above the second document contact surface and configured to read an image on the second side of the second document being conveyed by the document conveyor unit, wherein the second reading unit and the second document pressing member are disposed not to overlap the first reading unit and the first document pressing member when viewed from a direction perpendicular to the document holding surface, and wherein a downstream one of the first and second document contact surfaces in the conveying path intersects or is disposed below a reference plane, the reference plane extending along the same plane as an upstream one of the first and second document contact surfaces and overlapping the downstream one of the first and second document contact surfaces in a direction orthogonal to the downstream one of the first and second document contact surfaces.
