PROBLEM TO BE SOLVED: To facilitate attachment/detachment of a component and removal of a jam by simplifying a two-step opening/closing operation of a cover.SOLUTION: A first path and a second path are formed so as to function as described below. A cover is supported at a first opening angle when a connection member is at one end of the first path, and the cover is supported at a second opening angle, greater than the first opening angle, when the connection member is at one end of the second path. When a cover support member is rotated upward from the position where the cover is supported at the first opening angle, the cover rotates while interlocking with the upward rotation. When the connection member reaches the junction of the first and second paths, the connection member moves from the first path to the second path by the self-weight of the cover. |
