Problems solved by technology
This scanning method is slow, and it is easy to cause the problem of inconsistent paper feeding direction. Therefore, the existing technology has developed a double-sided scanning device, which can automatically scan two pages of a paper, so users can quickly complete two pages of a single paper. The scanning work of the page, while avoiding the problem of inconsistent paper feeding direction
[0003] In the double-sided scanning device, an existing design is to use two scanning modules to scan two pages of paper respectively, such as US Pat. The volume is too large, and the cost of the two scanning modules is also high. Therefore, the design of flipping the paper to achieve double-page scanning has been proposed, such as disclosed in US Patent No. US 5,430,536, which is at the entrance of the paper feeding path The section and the exit section are connected by a staggered path. When the paper finishes printing and scanning the first side, the paper feeding device will drive the paper back to the staggered path, and return to the paper feeding path from the staggered path for the second For two-sided printing and scanning operations, the paper must be repeatedly traveled through the entire paper feeding path, which lengthens the traveling path and consumes more time. In addition, the page order of the paper in the output tray will be reversed. So users need to reorder
[0004] In addition, U.S. Patent No. 5,438,435 discloses a double-sided scanning mechanism. However, it has the following disadvantages: the path of the document is complicated, and it is necessary to have a precise control of the paper guide device, otherwise it is easy to run the wrong path or cause paper jams. Increased probability; due to the complex path, there are many necessary paper feeding components, resulting in a relatively high part cost

Embodiment Construction
[0013] Please refer to figure 1 , figure 1 It is a schematic cross-sectional view of an embodiment of the duplex scanning device 100 of the present invention. The duplex scanning device 100 is used to capture images of the first page Pg1 and the second page Pg2 of a document P, and finally send the document P out of the duplex scanning device 100 . Please note that the document P processed by the double-sided scanning device 100 of the present invention is not limited to paper, but generally refers to any object (object) that can be scanned by the double-sided scanning device 100 , such as transparencies.
[0014] Such as figure 1 As shown, the duplex scanning device 100 includes a document conveying device 102, a first transparent element 104, a second transparent element 106, an image scanning module 108, a first platen element 110, a second platen element 112 , a first calibration sheet 114 , a second calibration sheet 116 and a scanning platform 118 . In this embodimen...

The invention provides a two-side scanning device which is used for selectively carrying out a single-side scanning work or a two-side scanning work. The two-side scanning device consists of a file transmitting device, a first transparent element, a second transparent element and an image scanning module; the image scanning module can be moved to one side of the first transparent element to capture the image of a page and to one side of the second transparent element to capture the image of another page.
Description
technical field [0001] The present invention relates to a double-sided scanning device, in particular to a double-sided scanning device capable of reversing documents for double-sided scanning and having a movable image scanning module for selectively performing single-sided or double-sided scanning operations . Background technique [0002] When a single-sided scanning device is used to scan two pages of paper, the user must manually turn over the paper after scanning one page, and then scan another page. This scanning method is slow, and it is easy to cause the problem of inconsistent paper feeding direction. Therefore, the existing technology has developed a double-sided scanning device, which can automatically scan two pages of a paper, so users can quickly complete two pages of a single paper. The scanning work of the page can avoid the problem of inconsistent feeding direction at the same time. [0003] In the double-sided scanning device, an existing design is to us...
