摘要： An image reading apparatus including a shading correction mechanism that can be formed by fewer component parts than conventional ones, and is increased in the degree of freedom of design, thereby enabling reduction of the size and weight thereof. A contact glass guides an original to an image reading position. A glass holding member holds the glass. A line image sensor reads an image on the original conveyed to the image reading location, through the contact glass. A reference member is disposed at a location different from the image reading location on the contact glass. A moving mechanism relatively moves the line image sensor and the reference member so that the line image sensor can alternatively read the original conveyed to the image reading location and the reference member. A drive section externally drives the moving mechanism to move the line image sensor and/or the reference member.

摘要： A sheet feeding apparatus comprises a conveying path formed between an upper and a lower units facing each other; a feed roller which feeds a sheet by a portion partially exposed from an upper surface of the lower unit to the conveying path; a separation member disposed to oppose the feed roller; a stopper which stops entrance of the sheet into the conveying path by abutting against a sheet end in a closed state in which the stopper is moved in a direction to intersect with an exposed surface of the feed roller; a driving unit which drives at least the feed roller and the stopper; and a control unit which controls the driving unit to rotate the feed roller through a predetermined angle in a sheet feeding direction and to then open the stopper when feeding of the sheet is started from the closed state of the stopper.
