Abstract:
A sheet material stacking device for stacking, at a stacking section which is provided at a downstream side, sheet materials which are transported from an upstream side, comprising:a pair of nipping and feeding members which are disposed at a sheet material transport direction upstream side of the stacking section, which receive the sheet materials which are transported from the upstream side, and which forcibly feed the sheet material to said stacking section; a guiding device which is disposed at the sheet material transport direction upstream side of said nipping and feeding members, and which guides said sheet materials which are transported from the upstream side into a gap between said nipping and feeding members which face each other, wherein said guiding device has a pair of guide plates disposed so as to form a tapered shape having a width which gradually reduces toward said gap; a sheet material transport section which is disposed at said sheet material transport direction upstream side of said guiding device, wherein said sheet material transport section has a transport mechanism which is formed by a plurality of narrow belts only, and transports said sheet materials by a weak nipping force; and wrap-around prevention boards corresponding to each of the pair of nipping and feeding members which prevent the sheet material which has passed through the nipping and feeding members from engaging again with said nipping and feeding members.
