Patent ID: 11021340

Abstract:
A sheet stacking device includes a conveyance part and a stopper. The conveyance part includes a tray and a conveyance member. On the tray, sheet stacks are stacked. The conveyance member conveys the sheet stack on the tray. The stopper is located on a downstream side of the tray and prevents the sheet stack from falling from the tray. The stopper has a main plate and an anti-slip member. The main plate is inclined upward. The main plate has a contact face coming into contact with the sheet stack and a bent face bent downward from a downstream side tip end of the contact face. The anti-slip member is provided from a downstream side end portion of the contact face to the bent face. A frictional coefficient between the anti-slip member and the sheet stack is larger than a frictional coefficient between the sheet stack and the contact face.
