The double-surface scanner with flip scanning unit comprises: a shell, a feeding mechanism to feed file along a channel included a front/middle/back segment, a scanning unit rotatable set in shell to scan the file on middle channel, and a driver. Wherein, the feeding mechanism first feeds the file from the front to the back segment along the channel, then the driver rotates the scanning unit scanning unit for 180deg, and the feeding mechanism feeds the file again for dual-surface scanning.

A method and apparatus for double-sided scanning of a paper document comprising diagonally offset scanner and traction pinch roller pairs thereby forming a zero-gravity traction feed. The zero-gravity traction feed allows the scanning apparatus to be oriented in varying positions while maintaining full operation. The scanner is adapted to scan a two-sided document by flip-flopping between two scanners whose field of views each face opposing sides of the document.

The invention relates to a horizontal CCD (charge-coupled device) two-sided line scanning system, and belongs to the technical field of machine vision image processing. The system comprises a horizontal scanning system support. The both ends of the horizontal scanning system support are provided with an extracting mechanism and a discharging mechanism; an upper CCD scanning mechanism is disposed between the extracting mechanism and the discharging mechanism; a first LED (light-emitting diode) controllable illuminant lighting device is disposed below the upper CCD scanning mechanism; a conveying device A and a conveying device B are disposed below the first LED controllable illuminant lighting device; a scanning opening is disposed between the conveying device A and the conveying device B; a second LED controllable illuminant lighting device is disposed below the scanning opening, and a lower CCD scanning mechanism is disposed below the second LED controllable illuminant lighting device. By using horizontal way to perform two-sided scanning, the system can scan multiple items side by side at one time; the items can be allowed to roll and continuously transport and a next plate can enter into the scanning area without waiting for the completion of one transport period, and therefore, production efficiency is greatly improved.

A food grain two-side scanning device provided by the application comprises a supporting frame and a scanning device mounted inside the supporting frame, wherein the scanning device comprises an upper scanner and a lower scanner which are arranged in an up-and-down manner and scanning surfaces of the upper scanner and the lower scanner are opposite; and a transparent plate which can move forwards and backwards in a horizontal plane is arranged between the upper scanner and the lower scanner. The supporting frame plays a supporting role, two side image acquisition of food grains is realized through the two scanners, and meanwhile, a movable shielding piece is additionally arranged to be used as a background during scanning, so that the scanning effect is better, the foundation is laid for image recognition of incomplete food grains, and problems that food grain image acquisition cost is high and the sampling efficiency is low in the prior art are solved; and in addition, the cost is low, the sampling efficiency is high, and the device for two-side scanning of a certain amount of the food grains in multiple directions is provided.

The utility model relates to a double-sided scanner, which is characterized in that two openings are arranged at the bottom of a feed box respectively, enabling a pickup roller and a combing roller pass through the opening, thereby the double-sided scanner begins to scan from the bottom of a pile of documents. The utility model has the advantage that a file of documents are scanned from the bottom using secondary double-sided scanning, therefore the scanned documents and the documents before scanning has the same order.

The invention provides a scanning device. The scanning device comprises a first scanning module and a second scanning module and is used for conducting double-side scanning on a manuscript to be scanned. The first scanning module comprises a first light source, a first imaging section and a first scanning window, an area which corresponds to the first imaging section and is located in a transmission channel is defined as a first scanning area, and an area which is located in the transmission channel and irradiated by a ray of light sent out by the first light source through the first scanning window is defined as a first irradiation area. The second scanning module comprises a second light source, a second imaging section and a second scanning window, an area which corresponds to the second imaging section and is located in the transmission channel is defined as a second scanning area, and an area which is located in the transmission channel and irradiated by a ray of light sent out by the second light source through the second scanning window is defined as a second irradiation area. The first scanning area is not overlapped with the second irradiation area, and the second scanning area is not overlapped with the first irradiation area. The scanning device is compact in structure, and simultaneously, light interference between the first scanning module and the second scanning module can be avoided.

The present invention relates to a device for document automatically entering and exiting and a method using the device to scan documents in two-sides; the device comprises an input tray, an exit tray, a scanning module, a first steering group, a second steering group, first to fourth paths, and an exit path. During double-sided scanning, documents can be sent to the scanning module through the first path to scan the first side; then the documents can be sent by the second path to the first steering group, and can be sent back to the first path consequently by the third path via the inversion of the first steering group, and can be scanned for second time by the scanning module; and then the documents can be sent to the second steering group along the fourth path, and next, under the help of the second steering group, the documents can be sent along the exit path to the first steering group, and then can be sent to the exit tray to finish the double-sided canning; via the paths and a first leading unit, the present invention can not cause repeated paths no matter how the documents are on the way of one-sided canning and double-sided canning, thereby avoiding paper blocking, solving the problem of ordering paper as well as shortening the canning path and time.

A double-side scan device for performing a single-side scan operation or a double-side scan operation selectively includes a document conveyer, a first transparent device, a second transparent device, and an image scan module. The image scan module moves to one side of the first transparent device to capture an image of one surface/side of a document and moves to one side of the second transparent device to capture an image of the other surface/side of the document, respectively.

The invention relates to a two-sided scanning device. A paper fetching roller is arranged on a paper feeding tray, and the two-sided scanning device starts scanning from the files nethermost a stack of files. The second-scanning type two-sided scanning device can achieve the effect that the sequence of the scanned files is the same as the sequence of the currently scanned files by performing scanning from the files nethermost the stack of the files. The two-sided scanning device can finish the two-sided scanning to achieve the effect that the sequence is the same as the original sequence only by passing through the scanning area twice, and compared with the prior third-scanning two-sided scanning device, the times of the files to pass through the scanning area during the feeding process is reduced by one time, therefore, the scanning time of the prior two-sided scanning device is obviously reduced; and in addition, compared with the single-sweep two-sided scanning device with two groups of scanning modules, the invention also saves the cost of a group of scanning modules.

A duplex scan method of detecting document size includes the steps of: (a) detecting size of a document and generating a size signal while moving the document from a sheet input tray to a reverse region; (b) moving the document across a scan region from the reverse region to the reverse region and scanning a back side of the document at the scan region according to the size signal; and (c) moving the document across the scan region from the reverse region to a sheet output tray and scanning a front side of the document at the scan region according to the size signal.
