Abstract
An image reading apparatus having an illuminating device for illuminating a film original, an image reading device for reading an image on the film original illuminated by the illuminating device and outputting image signals. The image reading apparatus further includes a type discriminating device for discriminating whether the film original is a first film original or a second film original having different film sizes, and a reading scope modifying device for modifying the reading scope of the image reading means according to the result of discrimination of the type discriminating means.

11. An image reading apparatus, comprising:
-
a photoelectric converter that outputs an image signal of an original;
an original type detector that determines whether the original loaded in the apparatus is one of a first original having a first size and a second original having a second size; and
a controller coupled to the photoelectric converter and to the original type detector, to determine a reading scope of the photoelectric converter based on the determination made by the original type detector. - View Dependent Claims (12, 13, 14, 15, 16, 17)

26. A storage medium that stores a control process for an image reading apparatus that has a photoelectric converter that outputs an image signal of an original that is scanned by the photoelectric converter, the control process comprising:
-
an original classification process for classifying an original loaded into the image reading apparatus as one of a first original having a first size and a second original having a second size different than the first size; and
a scanning variation process for changing a scanning range of the photoelectric converter based on a result of the original classification process. - View Dependent Claims (27, 28, 29)
