Abstract
A scanning device includes a first scanning unit having a first scanning element array to scan a first surface of a scan-target medium to acquire a first image, a second scanning unit having a second scanning element array to scan a second surface of the scan-target medium to acquire a second image, and an output unit that outputs a first image signal of the first image and a second image signal of the second image. The first scanning unit and the second scanning unit face each other to scan the first surface and the second surface concurrently. When the scanning directions of the first scanning element array and the second scanning element array are the same, a mirrored image acquired from one of the first image signal and the second image signal is inverted so that the output unit outputs normal images of the first surface and the second surface.
