Abstract
A sheet feed apparatus comprises a sheet stacking means, being able to be installed in and released from the main body of the apparatus, for stacking sheets, a sheet feed roller for feeding the sheets stacked on the sheet stacking means, and plural inclined plane members, disposed at the end of the downstream side of a sheet feed direction of the sheet stacking means, for coming into contact with the sheets fed by the sheet feed roller to separate them, wherein, among the plural inclined plane members, the height of the inclined plane member corresponding to the sheet feed roller is set to be lower than the height of the other inclined plane members, whereby a sheet feed cassette can be installed/released without any contact with the sheet feed roller, and the sheets can be fed without any fold of their edges.
