Abstract:
1. A sheet feeding apparatus comprising: first stacking means and second stacking means for stacking sheets thereon; first sheet feeding means for feeding the sheets stacked on said first stacking means a first transport path for guiding the sheets fed from said first stacking means; second sheet feeding means for feeding the sheets stacked on said second stacking means; a second transport path for guiding the sheets fed from said second stacking means; a common transport path, which said first transport path and said second transport path join; reading means for reading images of documents transported in said common transport path; moving means for moving said reading means between a first position away from said common transport path and a second position for reading the images of the documents transported in said common transport path; a single drive source for generating a driving force for driving said first sheet feeding means, or said second sheet feeding means and said moving means; and controlling means for controlling said single drive, source so that the driving force generated by said single drive source when said single drive source drives said second sheet feeding means and said moving means is greater than the driving force generated by said single drive source when said single drive source drives said first sheet feeding means.
