Charge-coupled devices (CCDs), the other kind of sensor often used in scanners, use mirrors to bounce light to a stationary sensor. Scanners using CISs are much smaller than ones that use CCDs, use typically a tenth as much power, and are particularly suitable for low power and portable applications, often powered over USB.
