Abstract
A device for conveying sheet members, the device includes a pair of feed rollers, a pair of resist rollers disposed on the downstream side of the pair of feed rollers, and a drive control unite. The drive control unite starts driving the pair of feed rollers when the pair of resist rollers are not rotating in the primary conveyance interval and stops driving the pair of feed rollers after the front end of the sheet member conveyed by the action of the pair of feed rollers has come into contact with the nip of the pair of resist rollers and a loop has been formed in the sheet member between the pair of feed rollers and the pair of resist rollers. Then, the drive control unit, first, starts driving the pair of resist rollers in the secondary conveyance and starts driving the pair of feed rollers after a predetermined delay time has passed, so that the loop of the sheet member will not excessively increase and will not substantially extinguish before the rear end of the sheet member separates away from the pair of feed rollers.
