Patent ID: 8773738

Claim:
A paper processing apparatus comprising: a paper transferor for sequentially transferring paper sheets along a paper transfer path while maintaining a predetermined interval between a certain paper sheet and a next paper sheet, a paper position detector for detecting a position of a paper sheet on the paper transfer path by detecting a leading end or a trailing end of the paper sheet supplied from a paper feeder, a plurality of processors, disposed on the paper transfer path, for performing predetermined processing to the paper sheet, an information reader for reading information relating to processing to be performed for the paper sheet using the processors, and a controller for controlling operations relating to the paper transferor, the paper position detector, the plurality of processors, and the information reader, wherein: upon judging that the trailing end of the certain paper sheet has passed through a certain processor on the basis of the position of the paper sheet detected using the paper position detector, the controller carries out adjustment of the widthwise position of the certain processor for the next paper sheet so as to be adapted for the processing for the next paper sheet on the basis of processing information relating to the next paper sheet obtained before the predetermined processing is performed using the certain processor.
