PURPOSE: To enable readily recognizing the distributing condition of sheets in such a way that display of the displaying part which is installed in response to each bin member is selected while it is done in association with the movement of a moving member which is moved in response to the sheet inserting part of a bin member.

CONSTITUTION: With the progress of duplication, moving members 181, 182 are sent down, and sheets are distributed into all the bins. A protruded part 183 is provided on the moving member 182, which is engaged with a microswitch 21 or 22, by which a light emitting diode 23 or 24 is lighted up. In other words, with the movement of the moving members 181, 182, for example, when the bin 5 becomes distributable, a lamp 24 in response to the bin 5 is lighted up, so that it helps an operator to recognize what ordinal numbered bin he is about to distribute.
