A compact duplex scanner for scanning both sides of an original document scans a document smoothly without paper jams. A platen roller 8 is located opposite an image sensor 7 for scanning a paper 15 held therebetween as it is transported through a paper feed path 2b. The image sensor 7 and platen roller 8 are mounted on a rotary frame 90 designed to move circularly as a single unit around a rotary shaft positioned transversely to the paper feed path 2b. After the paper 15 is carried in a forward direction P and the front 15a of the paper 15 is scanned, the rotary frame 90 rotates 180 degrees, and the paper 15 is carried in a reverse direction to scan the back 15b.

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.

A duplex scanning apparatus includes a sheet feeding tray, a sheet pick-up roller and a sheet separation roller. The sheet feeding tray includes a first opening and a second opening. The sheet pick-up roller and the sheet separation roller are partially received in the first opening and the second opening of the sheet feeding tray, respectively, so that the sheet pick-up roller and the sheet separation roller are sustained against documents on the sheet feeding tray. For performing duplex scanning operations on the stack of paper sheets, the documents are successively scanned from the bottommost paper sheet to the uppermost paper sheet. As a consequence, the scanned documents are stacked in the discharging tray in the same order as that of the original stack.

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.

The invention relates to an automatic file feeding device supporting single-side and double-side scanning and a file feeding method thereof. The automatic file feeding device comprises a feeding path, a positive scanning discharging path, a negative scanning path and a negative scanning discharging path, wherein the positive scanning discharging path is selectively connected with the negative scanning path through a door structure, a file on the way can push the door structure to open a certain angle, the negative scanning path is provided with a clutch and a paper clamping block, the clutch comprises a transmission part and a brake part, the brake part is separated from the paper clamping block when the transmission part is meshed with a feeding roll, and the transmission part is separated from the feeding roll when the brake part is meshed with the paper clamping roll. The automatic file feeding device has low cost, small appearance size, and high scanning speed because the image scanning space is controlled little as soon as possible, and adapts to a high-end or low-end scanner.

The duplex scanning apparatus includes a sheet feeding channel, a sheet transfer channel, an inverting channel, and a sheet sensing module. A first end of the inverting channel is connected to a junction between said sheet feeding channel and the sheet transfer channel. A second end of the inverting channel is connected to the sheet transfer channel. A distance between the sheet sensing module and the first end of the inverting channel is greater than a distance between the sheet sensing module and the second end of the inverting channel. When a document is transferred through the sheet sensing module at the second time, a next document is fed into the sheet feeding channel through a sheet entrance.

An automatic document feeder includes a first path extending from a feeding tray to a scanning module, a second path extending from the scanning module to a reversing roller unit, and a third path extending from the reversing roller unit to an intermediate portion of the first path. A document is moved from the feeding tray onto the reversing roller unit via the first and second paths for a first scanning. Just before the document is moved through the second path, the reversing roller unit is driven to allow the document to move therethrough. Subsequently, the document is reversed on the reversing roller unit to move through a looped passage defined by the third path, a portion of the first path downstream of the intermediate portion, and the second path for a second scanning. The reversing roller unit is operable to allow two opposite edges of the document to move thereon in different directions.
