摘要

An image scanning apparatus includes a reversal tray (180) on which printable media are temporarily stacked, and a reverse roller (160) installed inside a main body immediately before the reversal tray (180) at a junction between the reversal tray (180) and an end of a second moving path (S2), which is driven in both clockwise and anticlockwise directions by power transmitted via a discharge roller to guide one of the printable media towards and away from the reversal tray (180) along a second moving path (S2), wherein a feeder (110), a pick-up roller (120), a scanning unit (143), a discharge tray (170), and transport rollers (130) are installed on a first moving path (S1) in order to scan images from one side of the printable medium, and the reversal tray (180) and the reverse roller (160) are installed on the second moving path (S2) in order to scan images from the other side of the printable medium.
