A duplex scanning apparatus capable of switching a scanning background includes a pair of glass plates, a pair of background boards pivoted to the glass plates and a driving mechanism. The glass plates are disposed in a frame and overlapped with each other. The two glass plates define two scanning areas face to face. A portion of the frame adjacent to an outer surface of the glass plate defines a first color area of the scanning background corresponding to the scanning area. One background board is positioned above one glass plate, and the other background board is positioned under the other glass plate and away from the one background board. Each background board defines a second color area of the scanning background corresponding to the scanning area. The driving mechanism mounted in the frame drives the background boards to turn over with respect to the corresponding glass plates.

Scanning apparatus

A document guiding mechanism includes a document supporting tray, a gearwheel coupled to the document supporting tray, a right guiding unit, a left guiding unit and a single-way latch means. The right guiding unit includes a right guiding wall positioned on the document supporting tray and a right linear gear extended from the right guiding wall and engaged with the gearwheel. The left guiding unit includes a left guiding wall positioned on the document supporting tray and opposite to and parallel to the right guiding wall, and a left linear gear extended from the left guiding wall and engaged with the gearwheel. The single-way latch means interconnects the document supporting tray and at least one of the right guiding unit and the left guiding unit. The right guiding wall and the left guiding wall can be kept at a suitable position by the single-way latch means.

Document guiding mechanism

A paper feeding mechanism mounted to a shell includes a pickup mechanism, a transporting mechanism, a separation mechanism and a one-way clutch mechanism. The pickup mechanism includes a pickup motor having a rotating roller, a pickup roller and a pickup wheel. The transporting mechanism includes a transporting motor, a transporting roller, a transporting wheel and a transporting gear. The separation mechanism includes a separation roller, a separation gear and a separation wheel. The one-way clutch mechanism includes a one-way axle, a wiggling arm, a restoration elastic element fastened between the wiggling arm and the shell, and a releasing gear. The one-way axle passes through one end of the wiggling arm. The rotating roller of the pickup motor passes through the one-way axle. The releasing gear mounted to the other end of the wiggling arm is engaged with the transporting gear and the separation gear.

Paper feeding mechanism

A document feeding mechanism includes a driving shaft, a document blocking unit, a tray, an elastic unit and an actuating unit. The tray is pushed up to connect the document blocking unit by the elastic unit. The actuating unit is coupled to the driving shaft and abutted against the tray for pushing down the tray to separate from the document blocking unit. The actuating unit will be driven to allow the tray to be pushed to swing up by the elastic unit for blocking documents. The actuating unit will be driven to abut against the tray for pushing the tray to swing down for separating the tray from the document blocking unit for conveying the documents. Therefore, the document feeding mechanism has high reliability for blocking the documents.

Document feeding mechanism

A sheet guiding apparatus assembled on a shelf includes two guiding members, two adjusting plates, a first spring, two push bars, a second spring and two rotating members. The guiding member has a base board. A front of the base board defines a guiding portion defining a horizontal recess. Each adjusting plate is pivoted to an outside edge of the base board. The push bars are movably received in the horizontal recesses and capable of sliding in the horizontal recesses to drive the corresponding adjusting plates to rotate upward or free the corresponding adjusting plates therefrom. Each rotating member is pivoted to a front of the guiding portion. When the rotating member is turned down, the rotating member touches the push bar and pushes the push bar to move rearward so that further drives the adjusting plate to rotate upward till being perpendicular to the base board.
