<p>PURPOSE:To convert the conveying direction of a sheet with certainty by holding a sheet tip between a driven roller, planetarily moving on the circumference of a driving roller, and a sheet guide member parallelly installed in this driving roller and feeding it to the driving roller. CONSTITUTION:In this sheet conveyor, it is provided with two driving rollers 12, 13 rotatable at isoperineteric speed in relation to the position of a bush. A sheet S is uplifted by a suction cup 11, and the tip is made contact with the driving roller 13, while a driven roller 20 installed in linkage being made up of two levers 16, 18 is planetarily rotated counterclockwise on the circumference of the driving roller 12, and the sheet S is held between these rollers 12 and 13. Successively, the driving rollers 12, 13 and the driven roller 20 are all rotated clockwise and traveled forward and, after a tip of the sheet S is headed for the desired direction, movements of the driven roller 20 is stopped. Thus, a change direction of conveyance of the sheet can be done without fail.</p> |
