ABSTRACT:
Attributes of an original (image density and discrimination between a color image and a black-and-white image) stopped on a platen glass is read by a reading unit in which light is irradiated upward from a lamp and reflection light is finally read by an image sensor. Next, while carriages of the reading unit are moved rightward, an image of the original is read by the reading unit. After completion of the reading operation, the carriages are held at a position near an image reading end position. Then, the readout original is ejected from above the platen glass, and the next original is transported by an automatic document feeder so as to be stopped on the platen glass. Thereafter, while the carriages are moved leftward, attributes of the next original stopped on the platen glass are read.
