A flatbed scanning device of a paper feeding scanning equipment includes a device casing and a scanning module. The device casing includes a first glass plate, and a second glass plate spaced apart from the first glass plate and having a bottom surface. The scanning module is disposed in the device casing, and including a module body, a scanning assembly disposed in the module body, and at least one contact assembly disposed on the module body. When the scanning module is in an initial position, the scanning assembly is located below the first glass plate, and the at least one contact assembly abuttingly contacts the bottom surface of the second glass plate.

A follower roller mounting mechanism for a paper feeding apparatus is provided, which has at least one follower roller and a shaft passing through the follower roller. The follower roller mounting mechanism includes a base having a trough and a hole on a top surface thereof. The trough has a back wall, a bottom wall, and two opposite lateral walls. The bottom wall and the back wall are adjacent to each other. Each of the lateral walls has a sliding slot. The shaft is disposed inside the base passing through the trough via the sliding slot for making the follower roller protruding from the top surface through the hole. An elastic element is disposed between the shaft and the back wall for generating elastic force, pushing the shaft sliding along the sliding slot, and making the follower roller to constantly rise above the top surface through the hole.

A paper grabbing assembly is provided. The paper grabbing assembly includes: a base with a pivot seat disposed thereon, wherein the shaft is pivotally disposed on the pivot seat; a bearing plate, pivotally disposed on the base corresponding to the paper grabbing roller; a driven member, connected to one end of the shaft; a cam member and an elastic member, rotatablely fitted on the shaft. The elastic member frictionally contacts the cam member and the driven member respectively, such that the driven member rotates the cam member via the elastic member, for pressing the bearing plate away from the paper grabbing roller. Further, when the cam member is stopped, the elastic member slides relative to the cam member, such that the driven member may not be affected by the cam member, but continue driving the paper grabbing roller to rotate.

A paper pressing device disposed on one side of a paper track of a sheet feed scanner, corresponding to a scanning module on the other side of the paper track is provided. The paper pressing device includes two pivot seats, a pressing block, and an elastic element. The two pivot seats are respectively disposed at two lateral edges of the paper track. The pressing block is located across and above the paper track, and is pivotally disposed between the two pivot seats for being rotated and slid. The elastic element, pressing against the pressing block, is used to provide a normal force to push the pressing block to move linearly and rotate. By adjusting the position and angle of the pressing block, the paper is flattened onto the scanning module.

A scanning apparatus includes a body, a transparent plate, a scanning module, and a color reference slice. A paper-feeding track is formed within the body, and a scanning window is formed at a side wall of the paper-feeding track. A coupling groove is formed at an edge of the scanning window. Both the transparent plate and the color reference slice have an edge being inserted into the coupling groove, such that the transparent plate covers the scanning window while the color reference slice leans against a side surface of the transparent plate facing the paper-feeding track. The scanning module is disposed within the body corresponding to the scanning window, such that a paper to be scanned and the color reference slice are located in the same plane, and the color reference slice and the paper are scanned under the same optical conditions.

Scanning apparatus

A paper feeder includes a base, a roller adjacent to the base, a holder for holding a paper, and a torsional element. The holder has a pivot end and a movable end, wherein the pivot end is pivoted to the base. The torsional element is disposed at a position where the holder is pivoted to the base, and provides torsion to move the movable end of the holder to be pressed against the roller, such that a front edge of the paper is raised to be in contact with the roller. As the roller rotates, the paper is fed into a paper feed track by a frictional force.

A device for paper separating and guiding is provided for separating a first paper sheet from a plurality of second paper sheets, and guiding the first paper sheet into a paper-feeding apparatus. The device includes a first inclined surface and a second inclined surface adjacent to each other. The first inclined surface is used for arranging the first paper sheet and a part of the second paper sheets stepwise, so that the first paper sheet located at the top layer is protruding forwards. The second inclined surface is used for blocking the other second paper sheets to maintain the paper sheets on the first inclined surface to be arranged stepwise, so that the process for paper separating and guiding is accomplished.
