ABSTRACT:
A sheet feed device includes: a conveyor roller that rotates in a first direction; a separation roller rotatable in a second, reverse to the first direction, that nips a sheet with the conveyor roller; a sheet detector provided at a detecting position to detect a number of sheets; a pressure generator that generates a pressure to press the separation roller against the conveyor roller; a separation torque generator that generates a separation torque to convey the sheet on the separation roller in the second direction; and a controller that, if two or more sheets are detected, applies the pressure and/or the separation torque to the separation roller to separate the sheets until the detected number of sheets is decreased to be one, and that, after the number of sheets becomes one, controls the pressure and/or the separation torque to adjust a position of the sheet on the separation roller to a target position.
