    • A platen plate for supporting an ejection object for liquid droplets ejected from each nozzle on the bottom surface of a liquid ejection head can secure the flatness of the ejection object so as to appropriately eject ink as well as can prevent the contamination of the bottom surface of the ejection object. The platen plate is provided with a plurality of ribs raised from its bottom surface so as to extend in a conveying direction of a recording sheet and arranged at predetermined intervals in a width wise direction of the recording sheet, and out of a region where ink droplets ejected from the each nozzle are landed, the bottom surface of the recording sheet is supported with top faces of the ribs so as to define a distance between the recording sheet and the ink ejection surface, and within the region where ink droplets ejected from the each nozzle are landed, the rib top faces are formed to have a height, or the ribs themselves do not exist, so that the rib top faces are not brought into contact with the bottom surface of the recording sheet.
    • 用于支撑从液体喷射头的底表面上的每个喷嘴喷射的液滴的喷射物体的压板可以确保喷射物体的平坦度,以便适当地喷射墨水,并且可以防止底部表面的污染 喷射物体。 压纸板设置有从其底表面升起的多个肋,以沿着记录纸的输送方向延伸,并以记录纸的宽度方向上的预定间隔布置,并且在墨滴 从每个喷嘴喷射出来的记录纸的底表面由肋的顶面支撑,以限定记录纸和喷墨表面之间的距离,并且在从每个喷嘴喷出的墨滴的区域内 喷嘴着陆,肋顶面形成为具有高度,或者肋本身不存在,使得肋顶面不与记录片材的底表面接触。
