Paper sheet processor and method of processing paper sheet

Abstract

A paper sheet processor includes a paper sheet setting portion for setting a plurality of paper sheets approximately uniformed in face-and-back orientation, a feeding section for sequentially introducing the paper sheets set on the paper sheet setting portion one after another, a discriminator for discriminating at least face-and-back orientation of each paper sheet introduced, a first stacker as a main stacker, a second stacker as a sub-stacker having a smaller capacity than that of the first stacker, and a controller for controlling such that the paper sheet first fed and discriminated in face-and-back orientation by the discriminator and any paper sheets subsequently fed and discriminated to have the same face-and-back orientation as that of the first fed paper sheet are stacked in the first stacker, and the other paper sheets discriminated to be different in face-and-back orientation from the first fed paper sheet are stacked in the second stacker. Even when a bundle of paper sheets to be re-checked, which are approximately uniform in face-and-back orientation, are set in the paper sheet processor in erroneous-face-and-back orientation, the processor can rationally carry out face-and-back re-orientation by stacking the front-faced or back-faced majority part of the paper sheets in the main stacker having a larger capacity and stacking the back-faced or front-faced minority of the paper sheets in the sub-stacker having a smaller capacity.
