Abstract: A transportation device includes: a transportation section that transports a continuous paper; and an imaging unit that detects a transportation amount of the continuous paper which is transported by the transportation section. The imaging unit includes a lens barrel; a light irradiation unit disposed in the lens barrel and capable of radiating light on the continuous paper; a condensing lens which is disposed in a position farther than the light irradiation section with respect to the continuous paper in the lens barrel and condenses a reflected light when the light is radiated from the light irradiation section to the continuous paper; and an imaging element which is disposed in a position farther than the condensing lens with respect to the continuous paper P in the lens barrel and captures an image by receiving the reflected light condensed by the condensing lens.
