Document transported typed scanning mechanism

Abstract

The scanning mechanism includes at least a mechanism for transporting document and a scanning module. The document transportation mechanism includes at least a transmission roller and multiple supporting rollers. The multiple supporting rollers are leaned on the transmission roller, and document is passed through between the transmission roller and multiple supporting rollers. The scanning module scans the document transferred in the document transportation mechanism. The scanning module includes at least one optical sensing assembly to pick up image of document.

Description

technical field [0001] The invention relates to a document conveying scanning mechanism, and in particular to a document conveying scanning mechanism capable of effectively reducing the height of the document conveying mechanism. Background technique [0002] Please refer to figure 1 , which is a schematic diagram of a known file transfer mechanism. The document transmission mechanism 110 comprises a document transmission mechanism housing 112, three transmission rollers 114a, 114b, 114c, three idle wheels 116a, 116b, 116c, a split roller 118, a split plate 120, a file loading roller 122 and A motor 124. The motor 124 is located inside the document transport mechanism housing 112 . The document loading roller 122 is also located inside the document transport mechanism housing 112 for loading a document 150 . The separation roller 118 and the separation plate 120 are all configured in the inside of the file transfer mechanism housing 112, and the separation roller 118 wil...

Problems solved by technology

[0004] In the above-mentioned document conveying mechanism 110, since multiple groups of conveying rollers 114a, 114b, 114c and idler wheels 116a, 116b, 116c are arranged around the motor 124 in pairs respectively, and in order to pass through the separating rollers 118 and separate When the documents between the boards 120 can smoothly move between the transmission roller 114a and the idler 116a, the height of the distribution roller 118 and the distribution board 120 must be higher than the position of the transmission roller 114a and the idler 116a. Therefore, the arrangement positions of the motor 124, the separating roller 118, the separating plate 120, the conveying rollers 114a, 114b, 114c and the idler wheels 116a, 116b, 116c as described above will cause the height of the document conveying mechanism 110 to be very high.

Furthermore, since the file transfer mechanism 110 needs to use multiple sets of transfer rollers 114a, 114b, 114c and idle wheels 116a, 116b, 116c to transfer the file 150, the design of the mechanism is very complicated and difficult to design.

In addition, since the multiple sets of transport rollers 114a, 114b, 114c and idler wheels 116a, 116b, 116c only touch a very small area of ​​the document 150 when the document 150 is being transported, it is easy to cause poor transmission of the document 150, and even cause the document 150 to be stuck in the What happens inside the file transfer mechanism 110
