A card transport unit transports a card ejected one-by-one from a card housing section to a card processing section, and includes: a carriage that is moved in a carriage transport path provided between the card housing section and the card processing section; a contactless card reader that includes a contactless communication antenna making contactless communication with the card; and a support member that holds the contactless communication antenna at a position opposing the carriage transport path. The carriage includes a card transport mechanism that transports the card in a card transport direction intersecting a movement direction of the carriage, and the card transport mechanism includes a motor. The motor is arranged on an opposite side of the card, which is transported by the card transport mechanism, from the contactless communication antenna.
