Embodiment Construction

[0013] 1 and 2 are schematic diagrams showing two states of a double-sided scanning device according to a first embodiment of the present invention. As shown in Figures 1 and 2, the double-sided scanning device with a reversible scanning unit in this embodiment includes a housing 10, a paper tray 12, a conveying mechanism 20 installed in the housing 10, and rotatably installed in the housing. The scanning unit 30 in the body 10 , the scanning unit rotating mechanism 40 for rotating the scanning unit 30 and the output tray 50 .

[0014] The transport mechanism 20 includes a plurality of transport rollers 20A to 20D. It should be noted that it is also possible to replace the conveying rollers 20A to 20D with a plurality of conveying belts. The conveying mechanism 20 is used for conveying the document D to be scanned along the conveying channel 22 . The delivery channel 22 includes a front channel 22A, a rear channel 22C, and a middle channel 22B connecting the front channel 22...

Abstract

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.

Description

technical field [0001] The invention relates to a double-sided scanning device and a double-sided scanning method thereof, in particular to a double-sided scanning device with a reversible scanning unit and a double-sided scanning method thereof. Background technique [0002] A conventional duplex scanning device usually has two optical modules for scanning the front and back sides of a document respectively. Due to the high cost of the optical module, the price of the double-sided scanning device has been kept high. [0003] Another traditional duplex scanning device has only a single optical module, but in order to scan the front and back sides of a document, the document transport mechanism must feed the document back and forth three times and flip it twice. For example, the document feed mechanism first feeds the document so that the optical module can scan the front side of the document. Then, the document conveying mechanism performs the f...
