1. 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;
a fourth roller that is configured to nip the medium bundle between the third roller and the fourth roller and that is configured to transport the medium bundle;
a feeding roller that is configured to feed the medium bundle and a medium, the feeding roller being provided upstream of the first roller in the transporting direction; and
a separating roller that is configured to nip the medium between the feeding roller and the separating roller, and is configured to separate the medium, the separating roller being provided upstream of the first roller in the transporting direction, wherein
the separating roller is configured to switch a separation state in which the medium is separated and a non-separation state in which the medium is not separated, wherein
the separating roller is set to be in the non-separation state when the feeding roller feeds the medium bundle,
