Abstract
A plurality of containers store sheets to be fed, and a plurality of sheet guides bias the sheets in the containers toward a predetermined location. Detectors determine the positions of the sheet guides and output position data corresponding to the size of sheets disposed in each of the plurality of containers. A memory circuit store sheet size data for a plurality of sheet size groups, and include, and at least a portion of sheet sizes from the plurality of sheet size groups are of similar dimension. A first comparison circuit compares selected position data with sheet size data stored in the memory to determine if sheets in a selected container are included in either a first group, a second group or the similarly dimensioned portion of the first and second groups. A second comparison circuit compares position data other than the selected position data with sheet size data stored in the memory circuit to determine if sheets in a container other than the selected container are excluded from the similarly dimensioned portion when the selected position data corresponds to a sheet size included in the similarly dimensioned portion. A circuit determines the sheet size of sheets in the selected container based upon position data corresponding to a container other than the selected container when position data corresponding to the other container does not correspond to a sheet size in the similarly dimensioned portion.
