Claim:
1. A peripheral, comprising: an input tray supporting a large-size medium and a small-size medium, which is a hard medium smaller than the large-size medium; a horizontal passage; a feeding mechanism, which is disposed on a front end of the horizontal passage and transports the large-size medium and the small-size medium from the input tray into the horizontal passage to provide a sheet-fed scan mode to a user; two scanning modules, which are disposed on two sides of the horizontal passage and acquire a front side image and a reverse side image of each of the small-size medium and the large-size medium, respectively, when each of the small-size medium and the large-size medium is transported horizontally; a transporting mechanism comprising two transporting rollers, which are separately disposed on the horizontal passage and transport each of the small-size medium and the large-size medium through the horizontal passage past the scanning modules in a horizontal direction; a control module, which is electrically connected to the scanning modules, the feeding mechanism and the transporting mechanism, and digitizes the front side image and the reverse side image coming from the scanning modules; an output unit, which is electrically connected to the control module, and receives and outputs the front side image and the reverse side image; a flatbed scanning device providing a flatbed scan mode to the user, wherein the flatbed scanning device comprises a rotatable upper cover and a horizontal scan platen, the rotatable upper cover presses a document on the horizontal scan platen, and the input tray is disposed on the rotatable upper cover; and a case portion abutting upon the rotatable upper cover, wherein the transporting mechanism and the scanning modules are disposed in the case portion, and a vertical gap directly adjacent to the front end of the horizontal passage and disposed on a vertical plane is formed between the case portion and the input tray which forms one portion with the rotatable upper cover, wherein the horizontal passage, on which the front side image and the reverse side image of each of the small-size medium and the large-size medium are acquired by the two scanning modules, and the horizontal scan platen, which is lower than the horizontal passage, are disposed on left and right sides of the vertical plane, respectively; wherein the transporting mechanism defines a horizontal transportable gap between the two transporting rollers, and the two scanning modules are disposed in the horizontal transportable gap smaller than or substantially equal to 74 millimeters in the sheet-fed scan mode when a width of the large-size medium that can be accommodated within the horizontal passage and the feeding mechanism is substantially greater than or equal to 210 millimeters and when the feeding mechanism transports the large-size medium and the small-size medium, which are inclined, from the inclined input tray.
