Abstract

PURPOSE:To prevent a script from coming off from an upper guide so as to obliquely move during paper feed, by arranging a curled script retaining means on the inner upper surfaces of a pair of guides. CONSTITUTION:A curled script 12 is set on a script stacker 11, and a curled script retaining means 26 is laid sidelong on the script stacker after script guides are widthwise moved to the script 12. Accordingly, even though the curled script 12 tends to bulge upward, the load of a retainer plate 28 in the curled script retaining means 26 inhibits the script from bulging, and a bulging force gives a rigidity in an advancing direction (longitudinal direction), and the leading end of the script is pressed between a separating pad unit 13 and a feed roller 14. Further, the rotation of the feed roller 14 in the counterclockwise direction causes paper feed.
