An image processing apparatus includes an auto document feeder, and can simultaneously scans both sides of an original at a fixed scan position during one-time original feed. The image processing apparatus further includes a first scanning unit that scans a front side of the original in a single-sided scan and a double-sided scan; and a second scanning unit that scans a back side of the original in the double-sided scan. In the double-sided scan, the first scanning unit and the second scanning unit scan the original by using the same scaling method. The first scanning unit uses different scaling methods between the single-sided scan and the double-sided scan based on an original scan condition.

The invention provides a car-distributing module of real-name integrated circuit (IC) card. The car-distributing module comprises a scanning module which is used for scanning two sides of a 2nd-generation identity card and is located on a foundation, a reading module used for reading the 2nd- generation ID card, a non-contact read-write module of IC card, a contact-typed read-write module of IC card which is integrated on a the same horizontal plane which is a sole card passageway. The processes of checking, scanning and distributing are finished in a time-share mode. The foundation is further provided with a box which is used for holding the IC cards, a recycling box of IC cards, a control circuit, an actuating device and a data interface which is connected with a computer and a power source. The module has the advantages of integrating the checking part, the scanning part and the card-distributing part on the same horizontal passageway. The entrance of the reading module of identity card and the IC card exit are sharing a block mouth enabling the users to put the identity card into one block mouth so that all the steps of checking, scanning, and distributing can be finished. The adoption of the module can reduce effectively equipment cost, be convenient to operate, reduce the possibility of disoperation, save the time of distributing time, improve the efficiency of distributing cards and improve customer experience.

An image reading device and an image forming apparatus and methods thereof can achieve a duplex scanning operation and enable a user to easily arrange the scanned documents after being discharged. The image reading device may include a supply path coupled to a document supply port, a simplex document feeding path coupled to the supply path to first guide the document to the scan unit, a duplex document feeding path coupled to the supply path to second guide the document to the scan unit to scan a first surface of the document, and a duplex document circulating path to communicate with the duplex document feeding path and guide a second surface of the first surface scanned document to the scan unit.

A duplex scanning apparatus includes a flatbed scanning portion and an automatic document feeder. The flatbed scanning portion has a first scanning module. The automatic document feeder has a second scanning module. The first scanning module has a first normal line perpendicular to a horizontal plane. The second scanning module is disposed in an inclined channel, and has a second normal line. In addition, an included angle is defined between the first normal line and the second normal line. Since the second scanning module is not directly disposed over the first scanning module, the height of the duplex scanning apparatus is reduced.

A duplex scanning apparatus includes a passageway, a first optical module, a second optical module, a transporting mechanism and an elastic pressing member. The first optical module is disposed on one side of the passageway. The second optical module is disposed on the other side of the passageway. The transporting mechanism transports an original sheet through the passageway and past a first scan position of the first optical module and a second scan position of the second optical module, and images of front and reverse sides of the original sheet are obtained, respectively. The elastic pressing member, disposed between the first scan position and the second scan position, pushes the original sheet towards an original supporting plane.
