To provide a pre-stacking device that can improve productivity by stacking multiple sheets in a limited space.SOLUTION: A pre-stacking device includes: a housing in which a main conveying path and a pre-stacking conveying path are formed; a main conveying part that is capable of forward rotation to convey sheets along the main conveying path in a conveying direction and reverse rotation to convey sheets in a reverse conveying direction; a pre-stacking conveyance part that is capable of forward rotation to convey sheets on the pre-stacking conveying path to the main conveying path through a branching position and reverse rotation to convey sheets that have entered from the main conveying path through the branching position into the pre-stacking conveying path; and a branching claw that can be switched between a first attitude that allows sheets conveyed in the conveying direction on the main conveying path to pass through the branching position and allows sheets on the pre-stacking conveying path to enter the main conveying path through the branching position, and a second attitude that allows sheets conveyed in the reverse conveying direction on the main conveying path to enter the pre-stacking conveying path through the branching position.SELECTED DRAWING: Figure 2 【課題】限られたスペースで複数のシートをスタックすることによって、生産性を向上させることが可能なプレスタック装置を提供する。【解決手段】プレスタック装置は、主搬送路及びプレスタック搬送路が形成された筐体と、主搬送路に沿ってシートを搬送方向に搬送する順回転及び逆搬送方向に搬送する逆回転が可能な主搬送部と、プレスタック搬送路上のシートを分岐位置を通じて主搬送路に搬出する順回転、及び分岐位置を通じて主搬送路から進入したシートをプレスタック搬送路に搬入する逆回転が可能なプレスタック搬送部と、主搬送路上を搬送方向に搬送されるシートが分岐位置を通過するのを許容すると共に、プレスタック搬送路上のシートが分岐位置を通じて主搬送路に進入するのを許容する第一姿勢、及び主搬送路上を逆搬送方向に搬送されるシートが分岐位置を通じてプレスタック搬送路に進入するのを許容する第二姿勢に切替可能な分岐爪とを備える。【選択図】図２
