Claim 13:
14. A medium feeding mechanism comprising:
a plurality of feeders that feed media;
a transportation path that is coupled to the plurality of feeders and includes a bent portion;
a transporter that transports the medium on the transportation path;
a transportation control unit that controls the transporter; and
an arrival detection sensor that is disposed at the transportation path and senses arrival of a medium, wherein
the transportation control unit adjusts a transportation velocity of the medium transported by the transporter on the basis of medium information of the medium and a transportation route shape for the medium,
the transportation control unit controls the transporter by determining a transportation velocity for a following medium on the basis of a deviation between an arrival time of a medium and a reference arrival time determined in advance, medium information of the following medium, and a transportation route shape for the following medium, the arrival time being a sensing result provided by the arrival detection sensor,
the transportation path includes a plurality of individual transportation paths each coupled to each of the plurality of feeders and a joining transportation path joining the plurality of individual transportation paths together, and the transporter includes a plurality of individual transporters for transporting media on the plurality of individual transportation paths and a joining transporter for transporting the media on the joining transportation path, and
the transportation control unit controls the plurality of individual transporters and the joining transporter by determining a transportation velocity for a following medium on the basis of a deviation between an arrival time of a medium and a reference arrival time determined in advance, medium information of the following medium, and a transportation route shape for the following medium, the arrival time being a sensing result provided by an arrival detection
sensor disposed at the joining transportation path.
