ABSTRACT:
Suction ports (14) are provided in one end (15R) of a drum (10), connecting the interior (16) and exterior of the drum (10). Corresponding suction ports (34) are provided at a stationary side (5R), opposing the suction ports (14), respectively. A suction fan (32) is provided, which draws air from the interior (16) of the rotating drum (10) through the corresponding suction ports (34) and the suction ports (14). A printing medium M can be attracted and held onto the outer circumferential surface (11) of the drum (10) by virtue of negative pressure, by utilizing the negative pressure generated in the interior (16) of the drum (10) as the suction fan (32) rotates and a plurality of suction holes (12) extending in a radial direction and connecting the interior and exterior of the drum (10). A damper (38) is provided at the air outlet port of the suction fan (32), for opening and closing the outlet port of the fan (32).
