ABSTRACT:
A sheet feed device includes a first sheet cassette including an accommodating portion configured to accommodate a first plurality of sheets, and a second sheet cassette disposed on the first sheet cassette and including a holding portion configured to hold a second plurality of sheets, in which one or more characteristics of the first plurality of sheets is different than one or more characteristics of the second plurality of sheets. The sheet feed device also includes a sheet feeder including a sheet feed roller, and the sheet feed device is configured to selectively feed the first plurality of sheets and the second plurality of sheets in a sheet feed direction toward a recording unit. Moreover, the sheet feed device includes 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 of the first sheet cassette and with respect to the sheet feeder, and the sheet feed roller is configured to contact the second plurality of sheets on the holding portion that is inclined so as to increase in height in a direction toward the sheet separator.
