Image reader with a closed-state detector and image forming apparatus using same

An image reader comprising:

• a body;
• a closing unit which is pivotably supported by said body of the image reader at an axis of rotation;
• a first closed-state detector, arranged in the image reader on a side opposite to the axis of rotation, for detecting a closed state of said closing unit;
• a second closed-state detector, arranged in the image reader in the vicinity of the axis of rotation, for detecting a position of said closing unit;
• a first image reading unit, mounted on said body, for reading image information of an original document;
• a second image reading unit, mounted on said closing unit, for reading image information of the original document;
• a first reading point at which a first side of the original document is read by said first image reading unit;
• and
• a second reading point at which a second side of the original document is read by said second image reading unit,
• wherein said first reading point is other than on a glass platen, and
• wherein said first reading point, said second reading point, and said first and said second closed-state detectors are generally aligned in a direction substantially perpendicular to the axis of rotation.
