Abstract:
1. A paper sheet conveying device for conveying a paper sheet delivered from a pre-processing device to a post-processing device, comprising: a conveying path formed of at least four pairs of integrally operating conveying roller pairs arranged in parallel, each pair consisting of upper and lower conveying rollers for conveying a paper sheet held therebetween, and a controlling section for detecting the position of the paper sheet being conveyed and controlling the operation of said conveying rollers, wherein said conveying path is composed of a first-half conveying path formed of a plurality of the integrally operating conveying roller pairs and a last-half conveying path formed of a plurality of the integrally operating conveying roller pairs, said first-half conveying path has a first-half driving mechanism for controlling the rotational speed of the lower conveying rollers of said integrally operating conveying roller pairs of the first-half conveying path and a first-half vertically moving mechanism for vertically moving the upper conveying rollers of said integrally operating conveying roller pairs of the first-half conveying path, said last-half conveying path has a last-half driving mechanism for controlling the rotational speed of the lower conveying rollers of said integrally operating conveying roller pairs of the last-half conveying path and a last-half vertically moving mechanism for vertically moving the upper conveying rollers of said integrally operating conveying roller pairs of the last-half conveying path, and said controlling section is configured so as to control said first-half driving mechanism, said first-half vertically moving mechanism, said last-half driving mechanism and said last-half vertically moving mechanism depending on the position of the paper sheet being conveyed.
