Embodiment Construction

[0012] Rely on the basic common sense of this field below, in conjunction with accompanying drawing, the present invention will be further described:

[0013] In the double-sided scanning flatbed scanner of the present invention, the main scanner 1 and the second scanner 2 are driven by the same sliding guide rail 4, the main scanner 1 and the second scanner 2 are respectively located on the upper and lower sides of the original, and scan the original at the same time The pros and cons of . During the scanning process, the main scanner (1) and the second scanner (2) make synchronous reciprocating movements along the direction of the sliding guide rail (4), and the scanning positions of the two are kept consistent up and down.

[0014] The second scanner 2 is installed inside the cover plate 3, and the cover plate 3 can rotate around the sliding guide rail 4 as an axis. Its function is that the original document can be placed or taken away when the cover plate 3 is lifted; Fla...

Abstract

The invention discloses a double-sided scanning flatbed scanner comprising a main scanning device (1) and a transmission mechanism. The double-sided scanning flatbed scanner is characterized in that the main scanning device (1) and a second scanning device (2) are respectively positioned on the upper side and the lower side of a manuscript to simultaneously scan the front side and the back side of the manuscript; the second scanning device (2) is installed inside a cover plate (3); the cover plate (3) can rotate by taking a sliding rail (4) as an axis; meanwhile, the second scanning device (2) also rotates along the cover plate (3). The double-sided scanning tablet scanner can be used for carrying out high-precision double-sided scanning on various bills, identity documents and the like and is practical and simple.

Description

technical field [0001] The invention relates to a flatbed scanner, in particular to a scanner capable of completing double-sided scanning at one time. Background technique [0002] The steps of scanning an image with an existing flatbed scanner are: first lay the original to be scanned face down on the glass plate of the scanner, and the original can be a text manuscript or a photo of a drawing; then start the scanner and install it inside the scanner The movable light source starts scanning the original. In order to illuminate the manuscript evenly, the scanner light source is long and sweeps the entire manuscript along the y direction; the light irradiated on the manuscript passes through a very narrow gap after reflection, forming a light band along the x direction, and passes through the photoelectric The conversion element converts the light strip into an analog electronic signal, which is converted into a digital electronic signal by an A / D converter, and finally send...
