Abstract
A sheet conveying device has a supporting frame that supports a pick-up roller and that moves downward when a sheet is fed, a stepping motor that rotates the pick-up roller and moves the supporting frame downward, and a control portion that starts driving the stepping motor when a job is started and then increases a frequency of the pulse signal to a target frequency. The control portion keeps the frequency of the pulse signal not more than ½ of the target frequency at least until the pick-up roller touches the sheet first.
