A sheet feed device includes a first sheet cassette having an accommodating portion accommodating a first plurality of sheets and a second sheet cassette, disposed on the first sheet cassette, accommodating a second plurality of sheets. The sheet feed device also includes a sheet feeder configured to selectively feed the first plurality of sheets and the second plurality of sheets toward a sheet feed path, and a sheet separator configured to separate, one by one, the sheets fed by the sheet feeder. Specifically, the second sheet cassette is configured to move above the accommodating portion and with respect to the sheet feeder between a sheet feed position in which the sheet feeder contacts sheets accommodated in the second sheet feed cassette to a non-sheet feed position in which the second sheet feed cassette prevents the sheet feeder from contacting sheets accommodated in the second sheet feed cassette.
