    • 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).
    • 吸入口(14)设置在鼓(10)的一端(15R)中,连接滚筒(10)的内部(16)和外部。 相应的吸入口(34)分别设置在与吸入口(14)相对的静止侧(5R)处。 设置有抽风扇(32),其通过相应的吸入口(34)和吸入口(14)从旋转鼓(10)的内部(16)吸出空气。 通过利用在鼓(10)的内部(16)中产生的负压作为吸力,能够通过负压将打印介质M吸引并保持在滚筒(10)的外周面(11)上 风扇(32)旋转,并且多个吸入孔(12)沿径向方向延伸并连接滚筒(10)的内部和外部。 在吸风扇(32)的出风口处设置有用于打开和关闭风扇(32)的出口的阻尼器(38)。

    • A printing medium discharge apparatus used for discharging a printing medium from a rotary drum in an ink jet printer for printing a desired image onto the printing medium by an ink jet while holding the printing medium on the rotary drum, includes a printing medium carry and discharge device and a printing medium press device. The printing medium carry and discharge device carries thereon the printing medium from the rotary drum, on the printing medium an image having been printed, to make a non-image formation surface of the printing medium including no image formation region contact the printing medium carry and discharge device, and discharges the printing medium carried thereon to be moved apart from the rotary drum. The printing medium press device presses an image formation surface including an image formation region of the printing medium carried on the printing medium carry and discharge device, against the printing medium carry and discharge device, thereby to prevent the printing medium from floating up from the printing medium carry and discharge device while the printing medium is discharged by the printing medium carry and discharge device.
