This invention concerns a sheet guide unit which allows sheets of thinner sheets to be conveyed in a stable fashion when the sheet is conveyed in a sheet guide space between the printing cylinder and a sheet guide surface. The sheet guide unit has 1) a first air control means to control the supply air, which is blown from the air supply chamber through air vents provided in the upstream portion of the path, and conveys the sheet through the sheet guide space suspending over the downstream portion of the path; and 2) a second air control means to control the aspiration air, which is drawn into the aspiration chamber via a plurality of first aspiration vents in the downstream portion of the path, and exhausted from an aspiration port provided on one of the walls of the aspiration chamber.
