PURPOSE: To enable the structure to be simple and also enable piled sheets for each of sorter bins to be positively taken out by arranging a pull-out part in a sorter bin which stores sort sheets.

CONSTITUTION: On a handle 7 being moved to the direction as indicated by an arrow head, drawers 61 and 62 which are connected to the handle 7 by way of a lever 6, are pulled out allowing piled sheets on the bin 3 to be pulled out while they are selected by guide hoes 5 out of other sheets on the bin. This enables piled sheets to be easily taken out. In addition, the drawers 61 and 62 serves as an arrange unit as well, which arranges properly the rear end of sheets which normally stored in the bin. Moreover, a rib 4 is usually provided for the bin to reduce a frictional force with sheets, and also to strengthen the bin's structure.
