Embodiment
Scanner with double-sided scanning function provided by the utility model, its characteristics are to carry out simultaneously the duplex scanning at the file to be scanned front and the back side.The scanner of traditional platform formula can only be as the usefulness of single-sweep.If will be engaged in the duplex scanning work of file, then file must be done rescan, not only effort and time-consuming.Scanner with double-sided scanning function of the present utility model is at the dull and stereotyped downside of the printing opacity of scanner, disposes one group of bottom ray machine.And, then disposing one group of top ray machine at the dull and stereotyped upside of printing opacity, the top ray machine also can be along a side directions and the same moved further of bottom ray machine of printing opacity flat board.Have light supply apparatus and mirror group in the ray machine of top.Light supply apparatus is used for shining back face of document to be scanned, makes it to produce reflected light.The mirror group is then mutually vertical by two, and couples with the catoptrons at the dull and stereotyped folder of printing opacity 45 degree angles respectively and form.The function of mirror group promptly is the reflected light at the file back side is reflexed to the bottom ray machine, and the bottom ray machine is received.Bottom ray machine and according to the reflected light that is received carries out the scanning work at the file back side.It should be noted that the printing opacity flat board is the rectangular area that to separate with a center line be two equal and opposite in directions, shape is identical.Scanner is to see through a rectangular area scanning document, another zone then be used for making reflected light be able to by.
Please refer to Fig. 2, it shows the schematic perspective view according to the scanner with double-sided scanning function of a preferred embodiment of the present utility model.Printing opacity flat board 210 has the first side 220 parallel with directions X shown in the diagram, the second side 230 parallel with the Y direction.Printing opacity dull and stereotyped 210 and be divided into first side 220 and second side 230 half surrounded two equal and opposite in directions, the rectangular area that shape is identical--first area 240 and second area 250 by the length of side.Top ray machine 260 is configured in the upside of printing opacity flat board 210, along directions X and the same moved further of bottom ray machine (not being shown among the figure) that is configured in dull and stereotyped 210 downsides of printing opacity, makes scanner 200 can be engaged in the work of duplex scanning.
For making the explanation of the present utility model can be more detailed, referring again to Fig. 3, it shows the catoptrical synoptic diagram of advancing according to the file back side of the scanner with double-sided scanning function of preferred embodiment of the present utility model.Scanner 200 with double-sided scanning function includes printing opacity flat board 210, bottom ray machine 305 and top ray machine 260.Printing opacity flat board 210 has the first side perpendicular to page (being the directions X among Fig. 2), and the second side (first side and second side all be not shown in figure) parallel with the Y direction.Printing opacity dull and stereotyped 210 and as shown in two equal and opposite in directions about shown dividing into, rectangular area that shape is identical, this rectangular area is respectively first area 240, second area 250.Bottom ray machine 305 is configured in the downside of printing opacity flat board 210, and top ray machine 260 then is configured in the upside of printing opacity flat board 210.Bottom ray machine 305 can move on the first side, places the front of the file to be scanned 310 on the first area 240 on the printing opacity flat board 210 with scanning.And top ray machine 260 also can be along first side and bottom ray machine 305 same moved further.
Then include in the top ray machine 260 light supply apparatus 315, and two mutually vertically and respectively with the catoptrons 320 and catoptrons 325 at dull and stereotyped 210 folders of printing opacity 45 degree angles.Light supply apparatus 315 is configured in the top ray machine 260, is used for the back side of shot file 310 making file 310 backside reflection reflected light 330.And couple the mirror group that forms by catoptron 320 and catoptron 325, and then be used for reflective light 330, make reflected light 330 after penetrating second area 250, be able to be received by bottom ray machine 305, bottom ray machine 305 can scan the back side of file 310 in view of the above.
It should be noted that scanner 200 top ray machine 260 with it in conjunction with before, only possess the function (being the function of known scanner) that single-sweep is arranged.That is the bottom light supply apparatus 335 of this moment is positioned at along the first area 240 of Y direction and the below of second area 250, can shine the front face of document to be scanned that is cross-placed on first area 240 and the second area 250, in order to be engaged in the work of single-sweep.And at top ray machine 260 with after scanner 200 combines, the part of bottom light supply apparatus 335 below second area 250 promptly can crested or not luminous, so that the work of duplex scanning can be carried out smoothly.
The utility model is on the practice, and scanner 200 sees through first area 240 and comes scanning document 310.The effect of second area 250 then is used for making reflected light 330 to be penetrated, and is received by bottom ray machine 305.In addition, the configurable shade of the periphery of light supply apparatus 315 (not being shown among the figure) then has a slit (not being shown among the figure) on the shade, and the light that can make light supply apparatus 315 be sent only can penetrate this slit.Can avoid causing the generation of the not good parasitic light of scanning quality with this.315 of light supply apparatuses can be cold-cathode tube (cold cathode fluorescent lamp, CCFL) or discharge lamp (discharged lamp).
Please be simultaneously with reference to Fig. 4 A and Fig. 4 B, its show top of the present utility model ray machine can with the synoptic diagram of the synchronization-moving method of bottom ray machine.Fig. 4 A is the front view of Fig. 2, and Fig. 4 B then is the side view of Fig. 2.Have the top ray machine 260 of catoptron 320,325 and light supply apparatus 315, dispose pilot pin 410.Bottom ray machine 305 then disposes pin-and-hole 420.Top ray machine 260 can see through pilot pin 410 with combining of pin-and-hole 420 for it with the coupling mode of bottom ray machine 305.When bottom ray machine 305 when directions X moves, top ray machine 260 can be with bottom ray machine 305 same moved further.
It should be noted that, the geometry of each object only is an example of the present utility model among the embodiment, be not in order to limiting applicable elements of the present utility model, anyly be familiar with this technology personage and all can be adjusted and reach and the similar function of the utility model, but still do not break away from spirit of the present utility model.
The described scanner with double-sided scanning function of the utility model the foregoing description has the following advantages at least:
One, the function that has duplex scanning: the setting of top ray machine, and the scanning document of printing opacity flat board is regional and make separating of reflected light penetration region, makes scanner of the present utility model have the function of duplex scanning.
Two, the time of duplex scanning is the same with single-sweep: the top ray machine is with the same moved further of bottom ray machine, and file is positive and negative two-sidedly to be scanned by the bottom ray machine simultaneously.Therefore, scanning document positive and negative two-sided need do not scanned secondary.So the time that duplex scanning is spent is the same with single-sweep.
In sum; though the utility model discloses as above with a preferred embodiment; right its is not in order to limit the utility model; anyly have the knack of this technician; in not breaking away from spirit and scope of the present utility model; when can being used for a variety of modifications and variations, therefore protection domain of the present utility model when look application claim defined is as the criterion.
