However, a counting means for counting the separated paper sheets P is provided and stored in the storage unit. It may be detected that the predetermined number of paper sheets P have been separated.

This is because, in the separation preparatory operation, the end of the tongue piece 9 abuts against the end of the paper sheet P so that the end is separated, and the paper sheet P and the paper sheet P are in close contact with each other. range capable of forming the gap is due to is limited to the paper sheet P in a substantially constant number of upper integrated in stage 2.
Therefore, in S7b, when the number of sheets P that can form a gap between the sheets P and P that are in close contact with each other by performing the preparatory operation is 100, for example, When it is detected that the separation of the number of paper sheets P has been completed, the processing from S8b to S12b is performed, and the processing from S1b to S6b is performed, so that the separated paper sheets that have not yet undergone the separation preparatory operation are performed. A gap is formed between the sheet P and the paper sheet P, and the separation operation can be started.

  In S7b, when it is detected by the abnormality detection means that an abnormality has occurred in the separation operation and the feeding operation, or when it is detected that a predetermined number of sheets P have been separated, the processing from S8b to S12b is performed. And by performing the processing from S1b to S6b, a gap is formed between the closely contacted paper sheets P that have not yet undergone the separation preparation operation and the paper sheets P, and the separation operation is started. May be.

Further, when the paper sheets P accumulated on the stage 2 can be discriminated in advance as being non-government-pasted paper, the separation preparation operation may not be performed.
As described above, in the second embodiment, in addition to the effects of the first embodiment, when an abnormality is detected in the separation operation and feeding operation of the paper sheet P, or a predetermined number of paper sheets P When the separation is detected, the separation operation and the feeding operation are performed again after performing the separation preparation operation, so that the abnormality in the separation operation and the feeding operation can be reduced, and the pause rate of the apparatus is reduced. The effect that it can be made is acquired.
