Transport apparatus and image reading apparatus

A transport apparatus which transports a medium along a transporting path, the apparatus comprising:

• a first roller pair which is operated when power is transmitted from a first motor, and feeds the medium to a downstream side in a transport direction;
• a second roller pair which is disposed further on the downstream side in the transport direction than the first roller pair, which is operated when power is transmitted from a second motor, and which feeds the medium to the downstream side in the transport direction;
• a third roller pair which is disposed between the first roller pair and the second roller pair in the transport direction, and feeds the medium toward the second roller pair;
• a first transmission mechanism portion which transmits the power from the first motor to the third roller pair;
• a second transmission mechanism portion which transmits the power from the second motor to the third roller pair;
• and
• a control portion which controls operation aspects of each roller pair,
• wherein, in a case where the medium which is set in a set portion is transported, when the medium is fed toward the third roller pair by an operation of the first roller pair, and the medium is nipped by the third roller pair, the medium is fed toward the second roller pair by the first roller pair and the third roller pair, and
• wherein the control portion shifts a state where the power from the first motor and the power from the second motor are transmitted to the third roller pair, to a state where driving of the first motor is stopped and the third roller pair is operated by the power from the second motor, under a circumstance that the first roller pair, the third roller pair, and the second roller pair nip the medium.
