Abstract: A sheet feeding device has a feed roller with a plurality of large-diameter portions and a retard roller having a plurality of large-diameter portions alternately disposed with respect to the large-diameter portions of the feed roller. Originals are individually separated between the feed roller and the retard roller. The distance between the two rollers is automatically adjusted so that when a load caused by a separated sheet in a sheet feeding direction is large, the amount of overlap between the large-diameter portions of the two rollers is reduced, and when the load is small, the amount of overlap is increased. Thus, optimum separation is performed in accordance with the thickness of the sheet and the coefficient of friction of the surface of the sheet.

Abstract: A method of processing a signal in a bar code reader in which an optical signal provided by scanning a bar code is subjected to photo-electric conversion to provide an analog electrical signal, which is utilized to decode the bar code. The method includes scanning a bar code with a light beam whose diameter is small enough to detect thin bars and determining whether the bar code is a thin bar code or a thick bar code. If the bar code is the thick bar code, the reader employs data based upon analog electrical signals, whose frequency components higher than a first cut-off frequency determined for the thick bar code are cut off, as effective data. If the bar code is the thin bar code, the reader employs data based on analog electrical signals, whose frequency components higher than a second cut-off frequency determined for the thin bar code are cut off, as effective data.
