SHEET DISCHARGE DEVICE, IMAGE READING APPARATUS AND IMAGE FORMATION APPARATUS

Japanese Patent JP2023155373

A

To secure the consistency of sheets in various sizes.SOLUTION: A discharge tray 303 is provided with an upstream side support part 101, a wall surface part 100, a first support part 102 having a first inclined surface, and a second support part 103 having a second inclined surface. A swing guide 411 is arranged on the upper side of the discharge tray. When viewed from the width direction, in a case where a point at which the wall surface part and the upstream side support part intersect each other is defined as the first intersection point, a point at which the swing guide and the first support part intersect each other is defined as the second intersection point, a distance in the horizontal direction from the first intersection point to the highest first apex of the first inclined surface is defined as L1, the distance in the gravity direction is defined as H1, the distance in the horizontal direction from the first intersection point to the highest second apex of the second inclined surface is defined as L2, the distance in the gravity direction is defined as H2, the distance in the horizontal direction from the first intersection point to the second intersection point is defined as L4, and the distance in the gravity direction is defined as H4, the relation of L1
