ABSTRACT:
An image reader includes a first image-reader unit, mounted on a body of the image reader, for reading image information of an original document on a first image-reader section, a closing unit which is openably supported on the body of the image reader through a closing device, a second image-reader unit, mounted on the closing unit, for reading image information of an original on a second image-reader section, and a closed-state detector for detecting a closed state of the closing unit. The closed-state detector includes a photoemitter, a photodetector, and a light-blocking unit which blocks a light beam traveling from the photoemitter to the photodetector, by moving in operative association with the opening and closing operation of the closing unit.
