Abstract

A scanner includes a reading unit that reads an image of a paper, a medium feeding portion that is capable of selecting a first feeding mode in which a separation feeding for separately feeding a paper bundle in which a plurality of sheets of paper is overlapped with each other is performed and a second feeding mode in which a non-separation feeding for collectively feeding the paper bundle without separating is performed, and a pair of first transporting rollers and a pair of second transporting rollers that transport the paper fed by the medium feeding portion, in a case in which the medium feeding portion feeds the paper in the second feeding mode, a first driven roller and a second driven roller respectively constituting the pair of first transporting rollers and the pair of second transporting rollers are driven in a rotation direction where the paper is transported.

Dependent claims

An image reading apparatus comprising:

a reader that is configured to read an image of a medium bundle;
a first roller that is configured to transport the medium bundle toward the reader and that is provided upstream of the reader in a transporting direction in which the medium bundle is transported;
a second roller that is configured to nip the medium bundle between the first roller and the second roller and transport the medium bundle toward the reader;
a third roller that is configured to transport the medium bundle read by the reader and that is provided downstream of the reader in the transporting direction;

and
a driving source that is configured to drive the first roller, the second roller, the third roller and the fourth roller.

4 more elements

An image reading apparatus comprising:

a lower portion;
an upper portion that is provided above the lower portion and is configured to rotate relative to the lower portion to expose a transporting path on which a first medium and a second medium are transported, the first medium being thinner than second medium;
a reader that is configured to read an image of the first medium and an image of the second medium;
a feeding roller that is configured to feed the first medium and the second medium and that is provided at the lower portion;
a separating roller that is configured to nip the first medium between the feed roller and the separating roller, and is configured to separate the first medium, the separating roller provided at the upper portion;
a first roller that is configured to transport the second medium fed by the feeding roller toward the reader, the first roller being provided at the upper portion and between the feeding roller and the reader in a transporting direction in which the second medium is transported;
a second roller that is configured to nip the second medium between the first roller and the second roller and that is configured to transport the second medium toward the reader, the second roller being provided at the lower portion;
a third roller that is configured to transport the second medium read by the reader, the third roller being provided at the upper portion and downstream of the reader in the transporting direction;
a fourth roller that is configured to nip the second medium between the third roller and the fourth roller and that is configured to transport the second medium, the fourth roller being provided at the lower portion;
and
a driving source that is configured to drive the first roller, the second roller, the third roller and the fourth roller.
