The guide plate is arranged adjacent to the heat-resistant glass plate in a sheet convey direction. The first discharge holes are formed in the heat-resistant glass plate. Air is discharged upward through the first discharge holes. The second discharge holes are formed in the guide plate. Air is discharged through the second discharge holes in the widthwise direction of the paper sheet.
