| 1. A conveyer comprising:
a conveying device for conveying plural sheets in parallel lines along a transport path;
a strike member placed at a downstream position of said conveying device;
detectors for detecting a leading edge of each of said sheets on each line; and
a control device that calculates, based on respective widths and skew degrees of said sheets, transport amounts necessary
for letting the whole leading edges of said sheets of respective lines strike on said strike member, and drives said conveying
device to convey said sheets by the largest one of said calculated transport amounts so that said sheets strike at their leading
edges on said strike member and are bent flexibly, thereby to correct their skew,
wherein said detectors include a plurality of sensors, arranged for each line in a direction orthogonal to said transport
path, to detect skew degree, of each sheet on each line, from a difference in detection time of the leading edge of said sheet
between said sensors of the same line.
