Abstract

A sheet conveying device includes a conveying unit that conveys a sheet in a sheet conveying direction; a measuring unit that measures a position of a side edge of the sheet in a measurement area; a shielding unit having an end portion that is projected into the measurement area for shielding the sheet; a first determining unit that determines whether the shielding unit is detectable in the measurement area; and a second determining unit that determines whether the measuring unit has been mounted in the sheet conveying device based on a result obtained in the first determining unit.
