1. An image reading apparatus for reading image information from a sheet, comprising:
a cover unit provided rotatably about a first rotational axis and including an upper surface of said image reading apparatus;
a sheet conveying member configured to convey the sheet along a sheet conveying passage;
a conveying guide provided rotatably about a second rotational axis different from the first rotational axis and configured to guide the sheet fed by said sheet conveying member; and
a reading unit which includes a transparent member and a reading portion configured to read, through said transparent member, an image on the sheet fed by said sheet conveying member and which is provided rotatably about a third rotational axis different from the first rotational axis and the second rotational axis,
wherein said cover unit is rotatable between a closed position where said cover unit forms the sheet conveying passage in cooperation with said conveying guide and an open position where the sheet conveying passage is open, and
wherein in a state in which said cover unit is positioned in the open position, said transparent member is exposed to an outside of said image reading apparatus by rotation of said conveying guide and said reading unit.
