Abstract:
1. An opening and closing mechanism comprising: a movable member removably mounted relative to a main body of an apparatus; an opening and closing member having a cover portion, protrusions, and pivot shafts, the cover portion pivotable between a closed position and an open position around the pivot shafts, the cover portion configured to cover an interior of the main body at the closed position and open the interior of the main body to an outside of the main body at the open position, the protrusions protruding outward from positions of the cover portion adjacent to the pivot shafts; and shaft position adjusters to change positions of the pivot shafts while the cover portion pivots between the closed position and the open position, wherein the opening and closing member is arranged relative to the main body so that, on an imaginary plane perpendicular to a central axis of each of the pivot shafts, a projected portion of each of the pivot shafts on the imaginary plane is positioned to interfere with a projected portion of the movable member on the imaginary plane when the cover portion is placed at the closed position, and the cover portion is positioned so as not to interfere with a trajectory of movement of the movable member relative to the main body while the cover portion pivots toward the open position, and wherein each of the shaft position adjusters includes a guide member to guide a corresponding one of the protrusions or the cover portion and a connecting member having a first end portion pivotably connected to a corresponding one of the pivot shafts and a second end portion pivotably connected to the main body via a shaft.
