PURPOSE:To convey a sheet of record paper through air, by feeding a conveying passage, where the record paper is conveyed through, with air by means of a blast device from the rearward part of a record paper conveying part. CONSTITUTION:A guide plate 26 and a pressing roller 25 both are installed each in or rotatably supported on the upper part of an undulatable parallel four-bar link 24 in making each of fixed points 24c and 24d their supporting points. When the record paper P is short in length, other parallel four-bar links 24a and 24b are additionally standing up, and pressing rollers 25a and 25b are strongly contacted under pressure at a position of the said driven shafts 22a and 22b by each elastic device via a conveyor belt 23, while with guide plates 26a and 26b installed in these parallel four-bar links 24a and 24b, the record paper P is conveyed up to the position nearby the right end of the said tray 15. The record paper P being separated from contact with the conveyor belt 23 and the said pressing roller 25 is slidingly traveled on a receiving member 27 of the said record paper P and then stopped by a front striking plate 28 fixedly installed in the position nearby the end part of the receiving member 27. |
