Abstract
A first light intensity curve is defined as a relationship between a first light intensity and a distance from a first reading unit. The first light intensity represents intensity of light that is part of a reflected light reflected off a first irradiated subject positioned at a distance from the first reading unit and is received by a first light-receiving unit. The first light intensity curve has a first intensity value at a first distance and a second intensity value at a second distance. The first intensity value is equivalent to the second intensity value. The first distance is different from the second distance. A distance between the first reading unit and a first read position is set to the first distance. A distance between the first reading unit and a first reference member is set to the second distance.
