Claim Text:
1. A sheet conveying device comprising: a plurality of conveying roller pairs provided along a sheet conveying path, including a downstream-side conveying roller pair whose rotation is stopped at occurrence of jamming and an upstream-side conveying roller pair provided on an upstream side of the downstream-side conveying roller pair and continuously rotating at the occurrence of jamming; a movable guide portion for opening a sheet conveying path by moving one of rollers of at least the downstream-side conveying roller pair in the plurality of conveying roller pairs in a direction away from the sheet conveying path; and a control portion for executing control such that rotation of the downstream-side conveying roller pair in the plurality of conveying roller pairs is stopped at the occurrence of jamming and a conveying force for conveying a sheet of a stepping motor driving the upstream-side conveying roller pair becomes larger than the conveying force before the rotation of the downstream-side conveying roller pair is stopped.
