OPENING/CLOSING STRUCTURE

To provide an image formation apparatus which can ease the impact at the time of opening of an opening/closing member.SOLUTION: An opening/closing structure comprises: an opening/closing member capable of being opened/closed with respect to an apparatus body; and a connection member which connects the opening/closing member openably/closably to the apparatus body. The connection member has a leg opening link structure in which a first link member whose one end side is rotatably supported by the opening/closing member and a second link member whose one end side is rotatably supported by the apparatus body are connected such that the other end sides of them are rotatable and movable. The other end side of the first link member protrudes in the direction crossing the opening/closing direction, and a shaft part formed with a cam shape part with the longitudinal direction of the first link member as the major axis on the outer periphery is inserted to the long hole formed with the direction crossing the movement direction of the shaft part as the minor axis on the other end side of the second link member to be connected in a movable manner.SELECTED DRAWING: Figure 8 【課題】開閉部材の開放時の衝撃を緩和することができる画像形成装置を提供する。【解決手段】装置本体に対して開閉可能な開閉部材と、開閉部材を装置本体に対して開閉可能に連結する連結部材と、を備え、連結部材は、一端側が開閉部材に回転可能に支持された第１リンク部材と、一端側が装置本体に回転可能に支持された第２リンク部材とが、各々の他端側が回転可能且つ移動可能に連結された開脚リンク構造を有し、第１リンク部材の他端側は開閉方向と交差する方向に突出し外周に第１リンク部材の長手方向を長径とするカム形状部が形成された軸部が、第２リンク部材の他端側に軸部の移動方向と交差する方向を短径にして形成された長孔に挿通されて移動可能に連結されている。【選択図】図８
