Abstract: A sheet discharge device includes: a sheet discharge portion; a sheet stacking portion having a sheet stacking surface for stacking a sheet discharged from the sheet discharge portion; and a stopper in the sheet stacking portion against which, for alignment, the leading end of the sheet discharged from the sheet discharge portion is thrust. The stopper has a support portion, a restricting portion, and an urging mechanism. The restricting portion is supported pivotally on a pivot shaft on the support portion, and is arranged either in a retracted position to lie flat substantially horizontally along the sheet stacking surface or in a restricting position to stand upright substantially vertically to the sheet stacking surface. The urging mechanism urges the restricting portion, when in retracted position, in a direction from restricting position to retracted position and, when in restricting position, in a direction from retracted position to restricting position.
