    • There are provided a sucking unit having a recording medium transportation surface including a plurality of sucking holes, a decompression chamber communicating with the sucking holes and a sucking device for sucking air in the decompression chamber, and a delivering device for sucking a recording medium supplied onto the recording medium transportation surface of the sucking unit onto the recording medium transportation surface through the sucking hole by the sucking device, and delivering the recording medium from an upstream side of the sucking unit to a downstream side thereof. Each sucking hole of the sucking unit is formed by a through hole section communicating with the decompression chamber and a sucking chamber having a larger area of a sucking surface opposed to the recording medium than a sectional area of the through hole section.
    • 设置有具有包括多个吸孔的记录介质输送面的吸引单元,与吸孔连通的减压室和用于吸入减压室内的空气的吸引装置,以及用于吸入供给到 吸引单元的记录介质输送面通过吸引装置通过吸引孔输送到记录介质输送面上,并将记录介质从吸引单元的上游侧输送到其下游侧。 吸引单元的每个吸孔由与减压室连通的通孔部和与记录介质相对的吸引面的面积比通孔部的截面积大的吸引区形成。
