Abstract
In a sheet conveying unit, two conveying sections turn linked and spaced apart such that sheet jams arising in the course of conveyance through the conveying sections can be easily cleared single-handedly. Wherein the sheet-conveying unit functions to turn over, convey and store sheets in a dual-sided copying section inside a copying machine main body (1), it may include a main frame (30) that is withdrawable frontward from the copying machine main body (1); an intermediate tray (31) storing the reversed sheets; a lower conveyor (32); an upper conveyor (33); and a linkage (34). The upper and lower conveyors (33, 32) have upper and lower conveying guides (50, 45) and upper and lower conveying rollers (51, 46), respectively, and both conveyors are open/closable on the main frame (30) disposed above the intermediate tray (31). One end of the linkage (34) is pivotably fit in the upper conveying guide (50), and the other end is engaged in the lower conveying guide (45) so that both conveying guides (45, 50) turn linked and spaced apart at predetermined intervals and lock at the predetermined intervals.
