Movable assemblies for an image reader unit and a cover unit in an image formation apparatus

An image forming apparatus, comprising:

• a main chassis configured to accommodate an image forming unit configured to form an image on a recording sheet;
• an image reader unit arranged in an upper position with respect to the main chassis and configured to read an image formed on a sheet;
• a cover unit arranged in an upper position with respect to the image reader unit and configured to cover the image reader unit;
• a first movable assembly configured to rotatably support the cover unit to be rotatable with respect to the image reader unit;
• and
• a second movable assembly configured to rotatably support the image reader unit to be rotatable with respect to the main chassis about a rotational axis,
• wherein the first movable assembly includes:
• a support member configured to support the cover unit to be vertically movable with respect to the image reader unit, and
• a frame arranged to protrude to an exterior of the image reader unit in a direction orthogonal to a vertical direction and an axial direction of the rotational axis, and configured to accommodate the support member therein;
• wherein the first movable assembly includes a lower end situated below a lower end of the image reader unit;
• and
• wherein the second movable assembly is arranged immediately below the frame of the first movable assembly in both the vertical direction and the axial direction of the rotational axis.
