ABSTRACT:
Information indicating whether or not the current sorting operation is the final one is preset in a control section. Then, a bar code reader recognizes sorting information of paper objects by reading respective bar codes printed on the paper objects that are supplied one by one from a paper object supply section. A bar code erasing section erases the bar codes after the bar codes have been read, if the information indicating the current sorting operation is the final one is preset in the control section. If the current sorting operation is not the final one, the bar codes are not erased. The paper objects are sorted based on the sorting information recognized by the bar code reader, and stacked in stores. Being capable of erasing the bar codes printed on the paper objects before they are distributed to users, a paper object sorting apparatus of the present invention has an advantage that it is free from a possibility of giving the users uncomfortable feeling. Further, since the bar codes can be printed on the paper objects with a substance that can be checked by the naked eye, it is possible to check the printing quality of the bar codes.
