Abstract:
A sheet-feeding device includes: a first feeding roller configured to contact a sheet accommodated in a sheet-accommodation portion to feed the sheet; a second feeding roller movable between a non-feeding position and a feeding position; a driving source configured to generate a rotational driving force to the first feeding roller; a transmission portion configured to transmit the rotational driving force to the second feeding roller; a first sensor; a second sensor; and a roller actuating portion. The roller actuating portion is configured to: move the second feeding roller from the non-feeding position to the feeding position in a case where the second detector detects rotation of the first feeding roller is stopped during a sheet-feeding operation; and move the second feeding roller from the feeding position to the non-feeding position in a case where the first sensor detects the sheet-feeding operation is completed for the sheet.
