<P>PROBLEM TO BE SOLVED: To provide a carrying device capable of reducing vibration, while restraining reduction in carrying accuracy. <P>SOLUTION: This carrying device includes an annular carrier belt 31 having a plurality of belt holes for sucking paper P, sucking and holding the paper P supplied on a carrying surface 31a and carrying the paper P by moving endlessly, a suction fan 38 for sucking the paper P on the carrying surface 31a by sucking air via the belt holes, a paper sensor 39 for detecting the paper P supplied to the carrier belt 31 in a predetermined position on the carrying surface 31a, an encoder 37 for outputting a pulse signal with every predetermined rotation angle of a driven roller 33, and a control part for controlling the air volume of the suction fan 38 in response to a change in the area ratio, by calculating the area ratio being the ratio of the area occupied by the paper P carried by being sucked and held in the carrying surface 31a, by using detection output of the paper sensor 39, the pulse signal of the encoder 37, the size of the paper P and a distance between the continuously supplied paper P. <P>COPYRIGHT: (C)2013,JPO&INPIT |
