Abstract
In a conveyor of an image-reading device, a first path is defined by a path from the upper path to the lower path via the curved path. A second path is defined by a path from the upper path to the extension path. A first reading unit is disposed on the upper path and reads the first surface while the original sheet is on the upper path. A second reading unit is disposed on the upper path and reads the second surface while the original sheet is on the upper path. A third reading unit is disposed on the lower path and reads the second surface while the original sheet is on the lower path. When the reading section reads the original sheet, the conveyor conveys the original sheet through the first path or the second path.

An image-reading device comprising:
- a conveyor configured to convey an original sheet having a first surface and a second surface opposite to the first surface, the conveyor having:
- an upper path;
- a lower path disposed below the upper path;
- a curved path connecting the upper path and the lower path;
- and
- an extension path being connected to the upper path, the upper path branching to the curved path and the extension path, a first path being defined by a path from the upper path to the lower path via the curved path, a second path being defined by a path from the upper path to the extension path,
- a reading section configured to read the original sheet and having:
- a first reading unit disposed on the upper path and configured to read the first surface while the original sheet is on the upper path;
- a second reading unit disposed on the upper path and configured to read the second surface while the original sheet is on the upper path;
- and
- a third reading unit disposed on the lower path and configured to read the second surface while the original sheet is on the lower path,
- wherein when the reading section reads the original sheet, the conveyor conveys the original sheet through the first path or the second path.
An image-reading device comprising:
- a conveyor configured to convey an original sheet having a first surface and a second surface opposite to the first surface, the conveyor having:
- an upper path;
- a lower path disposed below the upper path;
- a curved path connecting the upper path and the lower path;
- and
- an extension path being connected to the lower path, the lower path branching to the curved path and the extension path, a first path being defined by a path from the lower path to the upper path via the curved path, a second path being defined by a path from the lower path to the extension path,
- a reading section having:
- a first reading unit disposed on the lower path and configured to read the first surface while the original sheet is on the lower path;
- a second reading unit disposed on the upper path and configured to read the second surface while the original sheet is on the upper path;
- and
- a third reading unit disposed on the lower path and configured to read the second surface while the original sheet is on the lower path, wherein when the reading section reads the original sheet, the conveyor conveys the original sheet through the first path or the second path.
An image-reading device comprising:
- a conveyor configured to convey an original sheet, the conveyor having:
- a common path;
- a curved path being connected to the common path;
- and
- a first path connected to the curved path, at least a part of the first path overlapping with at least a part of the common path with respect to a vertical direction;
- a second path connected to the common path and extending in a direction different from the curved path from the common path, the conveyor selectively performing a first conveyance and a second conveyance, wherein in the first conveyance the original sheet is conveyed from the common path to the first path via the curved path, and in the second conveyance the original sheet is conveyed from the common path to the second path;
- a reading section configured to read the original sheet and having a first reading unit, a second reading unit, and a third reading unit,
- wherein the first reading unit and the second reading unit being positioned with the common path interposed therebetween, and displaced in a direction in which the original sheet is conveyed, the first reading unit and the second reading unit reading the original sheet on the common path,
- wherein the third reading unit is disposed on the first path.
