An unstacking feeder capable of unstacking sheet materials efficiently from a sheet stack has a sheet stack transfer means (3) for transferring a sheet stack (1), which consists of a plurality of stacked sheet materials (1a), along a circulation transfer passage which passes a predetermined unstacking position. In order to separate individual sheet materials from a sheet stack in order, a floater (6) is selected and supplied automatically in accordance with the shape of the sheet materials by floater supply means (5, 7, 7d). Each unstacked sheet material is tranferred to equipment in the subsequence stage, such as a transfer feeder by sheet material transfer means (11, 10). During this time, each sheet material (1) separated by the floater (6) is transferred onto a sheet material transfer unit by a sheet material transfer means (9).
