Claim:
A paper sheet accumulating apparatus, comprising: a primary conveyer ( 2 ); a secondary conveyer ( 3 ); and an accumulation unit ( 4 ), the primary conveyer ( 2 ), secondary conveyer ( 3 ), and accumulation unit ( 4 ) being arranged in this order following a conveyance flow of a sheet material (W), the accumulation unit ( 4 ) including a posture conversion unit ( 35 ) for converting the sheet material (W) in a flatted posture into that in a standing posture by guiding the sheet material (W) from one end side thereof to a downward flow and a table top ( 7 ) for receiving the sheet material (W) at a lower position of the posture conversion unit ( 35 ) and accumulating the sheet material (W) in a longitudinally arranged state while supporting the reached sheet material (W) sequentially in a standup posture, the primary conveyer ( 2 ) including a flat conveyance plane ( 6 ) for holding the sheet material (W) in a flatted posture at a substantially same height as the table top ( 7 ) of the accumulation unit ( 4 ), and the secondary conveyer ( 3 ) being made able to convey the sheet material (W) received from the primary conveyer ( 2 ) in a rise inclined direction so that the sheet material (W) can be delivered by feeding to the posture conversion unit ( 35 ) of the accumulation unit ( 4 ), and having a first guide belt ( 12 ) and a second guide belt ( 13 ) that sandwich the sheet material (W) between the first guide belt ( 12 ) and the second guide belt ( 13 ) and convey the sheet material (W), the first guide belt ( 12 ) and the second guide belt ( 13 ) keeping parallelism thereof and being twisted along a conveyance direction so that top and bottom of the sheet material (W) being sandwiched is inverted.
