Abstract
A sheet feeding device () includes a placing plate () on which a sheet is placed; a pickup roller () which feeds the sheet to a conveying path (); a lift member () which is turned around a rotating shaft () to elevate the placing plate () and to make an downstream side end portion of an uppermost sheet in a conveying direction come into contact with the pickup roller (); a drive unit () which rotates the rotating shaft (); a variable resistor () which changes an electric resistance value depending on a rotating angle of the rotating shaft (); and a control part () which calculates the rotating angle of the rotating shaft () using the electric resistance value measured by the variable resistor () and detects an amount of the sheets based on the calculated rotating angle.
