Description
Technical field
The utility model belongs to the scanner auxiliary equipment, particularly a kind of autofile document feeder for list/duplex scanning.
Background technology
Because the scanner development rapidly, (Automatic DocumentFeeder, ADF) demand as photoprinter or a large amount of scannings increases scanner collocation autofile document feeder day by day.
Present autofile document feeder has function that supplies single-sweep and the function that supplies duplex scanning usually.
As shown in Figure 1, generally supply the autofile document feeder 10 of duplex scanning to comprise paper feed channel 12, scanning form 13, paper turning passage 14 and roller bearing 15.Because of autofile document feeder 10 only has a paper feed channel 12, therefore, no matter be scanning single face file or double-side file, its scanned document all needs just can leave autofile document feeder 10 through paper turning passage 14.
The structure of autofile document feeder 10 as shown in Figure 1 is no doubt convenient for the file of wanting scanning double-side, just can scan but must walk around paper turning passage 14 on the contrary for the file that will scan single face, makes sweep velocity be affected.And, be positioned at the roller bearing 15 of scanning on the form 13 when scanning not coplanar, must counter-rotating, cause the complicacy in mechanism and the control.
Summary of the invention
The purpose of this utility model provides a kind of autofile document feeder for list/duplex scanning.
The utility model system is disposed on the image capture unit, and it comprises paper distributing mechanism, scans window, is arranged at paper distributing mechanism and the paper feed channel, channel selector switch, the turn-over passage that is connected with paper feed channel and the paper delivery passage that scan between the window; Paper feed channel comprises and is connected in the single-sweep paper feed channel between paper distributing mechanism and the paper delivery passage and was connected before the duplex scanning paper feed channel channel selector switch between paper distributing mechanism and the turn-over passage is arranged at single-sweep paper feed channel and duplex scanning paper feed channel.
Wherein:
Before single-sweep file paper feed channel, be provided with the feeding box that is used for placing file to be scanned.
The rear of paper delivery passage is provided with the paper output box that is used for placing the file that has scanned.
Channel selector switch has the following guide surface that individual scanning document is guided to the last guiding face of single-sweep paper feed channel and individual scanning document is guided to the duplex scanning paper feed channel.
Single-sweep paper feed channel, duplex scanning paper feed channel, turn-over passage and paper delivery passage are respectively equipped with so as to driving the paper feeding roller bearing that the single sweep file advances.
Single-sweep paper feed channel, duplex scanning paper feed channel and turn-over passage are respectively equipped with so as to the paper sensor of individual scanning document position is provided.
Image capture unit is platform-type scanner.
Because the utility model system is disposed on the image capture unit, it comprises paper distributing mechanism, scans window, is arranged at paper distributing mechanism and the paper feed channel, channel selector switch, the turn-over passage that is connected with paper feed channel and the paper delivery passage that scan between the window; Paper feed channel comprises and is connected in the single-sweep paper feed channel between paper distributing mechanism and the paper delivery passage and was connected before the duplex scanning paper feed channel channel selector switch between paper distributing mechanism and the turn-over passage is arranged at single-sweep paper feed channel and duplex scanning paper feed channel.During scanning operation, by the control of channel selector switch, individual scanning document can enter single-sweep paper feed channel or duplex scanning paper feed channel; When selecting the single-sweep pattern, individual scanning document enters the single-sweep paper feed channel via the control of channel selector switch; At this moment, when the overscanning form, and its face down, reverse side are up with first direct of travel for file to be scanned, so be the positive image of scanning during the single-sweep pattern.And after file scan finished, the front end of file was introduced into paper output box, entered paper output box behind the rear end, and front face of document down.Therefore, when All Files all after the been scanned, the file order of its file order when being positioned over feeding box is identical.When selecting the duplex scanning pattern, file to be scanned enters the duplex scanning paper feed channel via the control of channel selector switch; At this moment, when file to be scanned during for the first time through the overscanning form system enter with second direct of travel, and the reverse side of file is down, so the scanning of the reverse side of the advanced style of writing of duplex scanning pattern part.Afterwards, file to be scanned enters the turn-over passage with second direct of travel, and via after the turn-over passage turn-over, enters the scanning form with first direct of travel.So, when file to be scanned during for the second time through the overscanning form system enter with first direct of travel, and front face of document is down, so the duplex scanning pattern is carried out positive scanning after for the scanning of carrying out reverse side earlier again.And after file scan finished, the front end of file was introduced into paper output box, entered paper output box behind the rear end, and front face of document down.Therefore, when All Files all after the been scanned, the file order of its file order when being positioned over feeding box 22 is identical.So no matter be single-sweep pattern or duplex scanning pattern, the rotation direction of all roller bearings of the present utility model all can not change, therefore do not need other control.Not only simple in structure, and easy to operate, can select single face and two-sided paper feed, thereby reach the purpose of this utility model.
