Abstract

In a sheet conveyance device, if a sheet has not been detected at a second position when a predetermined time has elapsed since the sheet has been detected at a first position, a separating portion switches operation thereof from a separating operation to a non-separating operation of conveying the sheet from upstream to downstream in a sheet conveyance path, and a sheet feed portion continues a feeding operation. If the sheet has not been detected at the second position by the time a predetermined time has elapsed since the separating portion has started the non-separating operation, the separating portion and the sheet feed portion stop driving, and if the sheet has been detected at the second position by the time, the separating portion switches operation thereof from the non-separating operation to the separating operation, and the sheet feed portion continues the feeding operation.
