<p>PURPOSE:To lighten the revolution torque by cutting the spiral grooves which can be engaged with the trunnion of each bin at least in one revolution onto each fix cam for transferring each bin between the distribution position and the sheet taking-out position. CONSTITUTION:On a fix cam 70 which transports a sheet which is distribution- accommodated into each bin 60 into the transport part to a staple tray, spral grooves 70 which can be engaged with the trunnion 60 of the bin 60 are cut in three revolutions. When the fix cam 70 is normally revolved in the (e) direction by a supporting shaft 71, the trunnion 61 of the bin 60 shifted to the bottom position from the distribution position is descended to a sheet taking-out position X3, guided by the spiral groove 70a. Here, the bin 60 which is tilted downwardly is elastically held onto a receiving member 72 urged upwardly by a spring 73, and guided by a sheet guide 78a projecting higher than a sheet counterflow preventing hook 60, and the sheet is sent into between a taking-out roller 75 and a pinch roller 75 by the dead weight. Thus, the revolution torque can be lightened, even if the pin shift stroke is long.</p> |
