As another error processing, it is also possible to adopt a configuration in which a measured amount of used paper is automatically excluded and stored in a trash box provided in the apparatus. Furthermore, it is also possible to put a measured amount of used paper into the pulper 14 and dispose of paper after disaggregation without processing it. In this case, water and disaggregated paper fibers are separated. It is sufficient if character recognition is impossible. The paper fiber generated at that time may be discarded as waste as it is, but it is preferable to reuse it again as a papermaking material.

  In addition, when the supply amount of recycled raw material is less than the unit processing amount and the old paper weighed in quantity is supplied to the pulper 14 and disaggregated, the pulp liquid obtained by disaggregation is used for paper processing for the subsequent processing. It is also possible to adopt a configuration in which the user can select whether to provide or discard as garbage.
