Abstract:
1. An image reading method for sheet media, comprising steps of: measuring and storing a sensor-to-sensor distance between a first image sensor disposed to a transportation path in which the sheet medium is conveyed and a second image sensor disposed to the transportation path downstream from the first image sensor; setting a point before a sheet medium reaches the first image sensor as a first reading start point; setting a point that is before the sheet medium reaches the second image sensor and is after the sheet medium is conveyed the sensor-to-sensor distance from the first reading start point as a second reading start point; setting a point after the sheet medium has finished passing the second age sensor as a first reading end point and a second reading end point, capturing first image information containing a first side of the sheet medium from the first reading start point to the first reading end point by means of the first image sensor; capturing second image information containing a second side of the sheet medium from the second reading start point to the second reading end point by means of the second image sensor; and removing a sensor-to-sensor distance portion of image information from an area not including first-side image information in the first image information.
