The inkjet heads H1-H5 are arranged in the circumference of a movement path of the can body 5. The inkjet heads H1-H5 are also arranged at mutually-different positions in the height direction. The can body 5 sequentially passes through the first inkjet head H1 to the fifth inkjet head H5. While the can body 5 passes through the respective inkjet heads H1-H5, ink is discharged to the outer peripheral surface of the can body 5 from the respective inkjet heads H1-H5.SELECTED DRAWING: Figure 4 |
