Abstract:
A sheet processing apparatus includes a fixed tray and a movable tray. The fixed tray is fixed at its downstream portion in a sheet transport direction and includes a sheet loading surface. A downstream portion of the sheet loading surface of the fixed tray is positioned at a higher level than an upstream portion thereof. The movable tray is pivotally supported, at its upstream portion, by a pivot support provided on the fixed tray. An angle between a sheet loading surface of the movable tray and a horizontal direction is more gentle than an angle between the sheet loading surface of the fixed tray and the horizontal direction.
