To construct a mechanism for inserting a photographic paper ejected out of a print unit into a bag material in a streamlined configuration.

A bag material X is set at a position to which a photographic paper P is ejected from an ejecting section of the print unit. After the photographic paper P has been put into a storage space Xa of the bag material X, a bagging apparatus C that delivers the bag material X to a transfer belt 13 is attached removably to the print unit, and a bagging controller 36 of the bagging apparatus C is connected to a controller of the print unit via connectors 36A, 11A. The bagging controller 36 carries out bagging operation based on a control signal from the print controller.
