    摘要: 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.

    摘要: A medium conveying apparatus includes a medium tray, a pair of side guides to regulate a width direction of a medium, and a housing on which the medium tray is located and including a conveyance path capable of conveying the medium placed on the medium tray. The pair of side guides are located on the medium tray so that outer ends of the pair of side guides can be positioned from an inside of the medium tray to an outside of a maximum width of the medium tray. The conveyance path can convey a medium having a width of an inside of the pair of side guides even when the outer ends of the pair of side guides are positioned outside the maximum width of the medium tray.
