| 1. An image reading apparatus, comprising:
a sensor section which includes a color line sensor which reads a color image and a monochrome line sensor which reads a monochrome
image provided in parallel with and a specific distance away from the color line sensor;
an input section which inputs a document image to the color line sensor and the monochrome line sensor;
a control section which, when reading an image from a document by use of the input section, starts the reading of an image
by the color line sensor and the reading of an image by the monochrome line sensor with the same timing;
a counter which counts a number corresponding to the specific distance by which the color line sensor and the monochrome line
sensor are separated;
a first storage section which stores an image read by the monochrome line sensor;
a second storage section which stores an image read by the color line sensor; and
a start control section which starts to store an image read by either the color line sensor or the monochrome line sensor
provided in a position corresponding to the trailing edge in the image reading direction of the sensor section, after the
counter has counted the number corresponding to the specific distance.
