Claims

[Scope of Claim for Utility Model Registration] An image forming apparatus comprising a document ejection tray provided at the top of a lid that can be opened and closed as needed, wherein the document ejection tray is rotatable in a direction perpendicular to the document ejection direction. a shaft; an arm protruding from the circumferential surface of the rotation shaft in a direction perpendicular to the central axis direction of the rotation shaft; a plate provided at one end of the rotation shaft; connected to one end of the plate; an elastic body that applies a rotational force to the rotation shaft so that the arm is pressed against the document stacking surface of the document ejection tray; and the lid body is fixedly disposed within the main body of the apparatus in which the lid is housed with the lid closed. , when the lid body is closed, the arm engages with the plate to rotate the rotation shaft against the rotational force of the elastic body until the arm is housed in a position that does not interfere with ejection of the original; and a stud that is disengaged from the plate when the lid body is opened so that the rotation shaft is rotated according to the rotational force of the elastic body until the arm comes into pressure contact with a document that has already been accommodated. An image forming apparatus characterized by:
