Description
Technical field
The present invention relates to a kind of paper feeding scanner, particularly relate to a kind of paper feeding scanner that carries out duplex scanning.
Background technology
Present common on the market scanner, except falt bed scanner, another kind disposes automatic paper feeder (ADF; Automatic document feeder) paper feeding scanner little by little is subjected to user's favor, its characteristics are when the user need be scanned a folded file, the user only needs paper is placed on the paper feed pallet of automatic paper feeder, automatic paper feeder will be opened the scan module that is orderly sent in the scanner and scans putting in order stacker, and then finishes scanning work automatically and save operating time and human resources.
And developed at present the paper feeding scanner that, can be in the transport process of paper simultaneously or finish the duplex scanning action of paper in regular turn, Fig. 1 shows and existingly is provided with two scan modules and can carries out the structural representation of the paper feeding scanner of duplex scanning.With reference to Fig. 1, paper feeding scanner 1 comprises automatic paper feeder 11 and scanner 12.Automatic paper feeder 11 comprises paper taking module 111, scanning window 112, scan module 113 and U type paper feed passage 114, and U type paper feed passage 114 then includes gets paper section 114A, paper counter-rotating section 114B and scanning section 114C.Wherein, paper taking module 111 is arranged on to be got in the paper section 114A, in order to the paper S to be scanned inside of feed-in automatic paper feeder 11 in regular turn.112 of scanning windows are transparent window, are arranged on the scanning section 114C.Scan module 113 then is arranged on the top of the other scanning window 112 of scanning section 114C, in order to the image of first S1 reading paper S.In addition, scan module 113 includes light source 113A, reflector group 113B, set of lenses 113C and Charged Coupled Device 113D.
Continuation is with reference to Fig. 1, and scanner 12 is arranged at the below of automatic paper feeder 11, includes scanning window 121 and one scan module 122.Scanning window 121 is a transparent window, equally also is arranged on the scanning section 114C.122 of scan modules are to be used to read paper S image when being used for carrying out platform-type scanning and paper feed type scanning in the scanner 12, and when scanner 12 was carried out paper feed type scannings, 122 of scan modules can be moved to the below of scanning window 121 and read the image of second S2 of paper S.In addition, scan module 122 comprises light source 122A, reflector group 122B, set of lenses 122C and Charged Coupled Device 122D.
Continuation is with reference to Fig. 1, in above-mentioned existing paper feeding scanner 1, because scan module 113 and 122 is positioned at the scope of scanning section 114C equally, therefore, be subjected to the interference of light source 113A and 122A each other between two scan modules 113 and 122 easily and make the phenomenon (or claiming shadow effect) of scanning result generation image overlap, thereby have influence on the quality of scanning of paper feeding scanner 1.For instance, when scan module 113 is reading the image of first S1 of paper, the image of second S2 of paper will be subjected to the irradiation of scan module 122 inner light source 122A and project on the scan module 113, causes scan module 113 to receive the image of first S1 of paper and second S2 of paper simultaneously and makes the phenomenon that occurs image overlap in the scanning result.
