Abstract

A sheet feed device includes a sheet storage portion, a pick-up unit, a sheet-feed separation unit, and an air blower. The sheet storage portion stores a stack of sheets. The pick-up unit picks up the sheets stored in the sheet storage portion. The sheet-feed separation unit separates and feeds one by one the sheets picked up by the pick-up unit. The air blower blows air against a lateral side face of the stack of sheets stored in the sheet storage portion. The pick-up unit picks up the sheets while the air blower blows air and before the sheet-feed separation unit starts to operate.
