(57) A delivery device in a sheet-fed offset rotary printing press includes a plurality
of suction units (10A-10E), at least one discharge unit, at least one support member,
and an intake source, air exhaust system, and switching device. The plurality of suction
units are arranged above a pile board (7) on an upstream sheet convey direction side
below a sheet under conveyance in a widthwise direction of the sheet, and draw by
suction the sheet under conveyance in slidable contact with it. At least one discharge
unit (80A-80C) replaces one of the plurality of suction units which is other than
those on two ends, and discharges air outwardly in the widthwise direction of the
sheet under conveyance. One of the plurality of suction units which is other than
those on the two ends and the discharge unit can be mounted selectively on at least
one support member (25E). The intake source (101), air exhaust system, and switching
device supply suction air to the suction unit when the suction unit is mounted on
the support member, and supply discharge air to the discharge unit (80A-80C) when
the discharge unit is mounted on the support member.
