A separator for segregating alternate sheets of paper traveling in a sequential stream and directing them into different exit passages comprising a housing, a guide and a bi-stable apparatus. The housing defines an entry passage and a pair of exit passages. The guide is constructed for alternately deflecting the sheets in said stream into different exit passages. The bi-stable apparatus mounts the guide between the entry and exit passages of the housing so that the guide has two stable positions and the guide shifts between these positions in response to a sheet of paper passing by it into one of the exit passages. Sheets of paper enter the separator through the entry passage in the housing and are deflected by the guide into one of the two exit passages depending on the position of the guide at the time the sheet enters the separator. As individual sheets of paper travel past the guide and engage it, they cause it to shift to its other stable position. In its alternate position the guide deflects the next succeeding sheet of paper into the other exit passage. Thus, the guide cycles between two positions to direct alternate sheets in alternate directions.
