Description

Miniaturization paper feed type Double face scanner

Technical field

The utility model relates to a kind of miniaturization paper feed type Double face scanner.

Background technology

Fig. 3 shows a kind of schematic diagram of known two-sided paper feeding scanner 100.In known two-sided paper feeding scanner 100, adopt two scan modules 110,120 to scan the file of being presented simultaneously.Two scan modules 110,120 are arranged in the housing 130.Need be formed with paper-feeding channel 132 in the housing 130.In order to allow each scan module 110,120 can carry out correction program, need in scanning area 140, be provided with and proofread and correct blank 150,160.Tarnish for fear of proofreading and correct blank, preferably will proofread and correct blank 150,160 and be arranged on beyond the paper-feeding channel 132.Therefore, the part 134 of paper-feeding channel 130 need be formed by clear sheet, and so, scan module 110,120 just can carry out scanning operation to proofreading and correct blank 150,160.In addition, traditional clear sheet and scan module 110,120 be arranged in parallel, be positioned at upper left scan module 110 and need correspond to the correction blank 160 that is positioned at the lower left, need correspond to and be positioned at top-right correction blank 150 and be positioned at bottom-right scan module 120, therefore quite take up room, and be unfavorable for the miniaturization of scanner, do not meet the demand of the miniaturized electric subset of modern trend.

The utility model content

Therefore, a purpose of the present utility model provides a kind of miniaturization paper feed type Double face scanner, by the suitable spatial configuration of reference colour table and scan module, and can be so that the volume of Double face scanner be minimized.

For reaching above-mentioned purpose, the utility model provides a kind of miniaturization Double face scanner, its comprise first scan module, first with reference to colour table, second scan module and second with reference to colour table.First scan module is used for the front at the first scanning area scanning document.First is arranged at first scan module with reference to colour table.Second scan module is relative with first scan module, is used in the scanning first of second scanning area with reference to colour table and back face of document.Second is arranged at second scan module with reference to colour table.First scan module is further used for scanning second with reference to colour table.

By this, can allow first and second scan module toward each other, and dwindle two spaces that scan module is shared, and then dwindle the overall volume of scanner.

For foregoing of the present utility model can be become apparent, a preferred embodiment cited below particularly, and conjunction with figs. are described in detail below.

Embodiment

Fig. 1 is the schematic diagram that shows according to the miniaturization paper feed type Double face scanner of the utility model preferred embodiment.As shown in Figure 1, the miniaturization Double face scanner of present embodiment comprise first scan module 10, first with reference to colour table 20, second scan module 30 and second with reference to colour table 40.First scan module 10 and second scan module 30 are formed the part of paper feeding channel 60.In addition, Double face scanner can also comprise paper delivery mechanism 50 and processor 70.Processor 70 is coupled to first scan module 10 and second scan module 30.Paper delivery mechanism 50 comprises several rollers 51-54, in order to file D is presented by being positioned at the first scanning area R1 and the second scanning area R2 on the paper-feeding channel 60.

First scan module 10 comprises first platform 12, first light source 14, first lens 16 and first image sensor 18, in order to carry out scanning motion, just at the positive DF of the first scanning area R1 scanning document D.First is arranged at first scan module 10 with reference to colour table 20.In the present embodiment, the outer surface 12A of first platform 12 is arranged on the inner surface 12B of first platform 12 with reference to colour table 20 in the face of second scan module 30, the first, and first platform 12 is the printing opacity platform.

Second scan module 30 is relative with first scan module 10, and comprise second platform 32, secondary light source 34, second lens 36 and second image sensor 38, in order to carry out scanning motion, just at second scanning area R2 scanning, first the back side DB with reference to colour table 20 and file D.Second is arranged at second scan module, 30, the first scan modules 10 with reference to colour table 40 is further used for scanning second with reference to colour table 40.In the present embodiment, surperficial 32A is arranged within second platform 32 on the surperficial 32B with reference to colour table 40 in the face of first scan module 10, the second outside second platform 32, and second platform 32 is the printing opacity platform.

First scan module 10 can with second scan module, 30 complete matchings.For example, the edge 10A of the first scan module 10 edge 30A of second scan module 30 that aligns.Perhaps, two edges 10A, the 10B of first scan module 10 two edges 30A, the 30B of second scan module 30 that can align respectively.Thus, effectively dwindled two spaces that scan module is shared.

In order to carry out calibration function, processor 70 can be proofreaied and correct the first sweep signal SS1 of the positive DF gained of the first scan module 10 scanning document D according to first scan module, 10 scannings, the second first reference signal SR1 with reference to colour table 40 gained, and proofreaies and correct the second sweep signal SS2 of the back side DB gained of the second scan module 30 scanning document D according to second scan module, 30 scannings, the first second reference signal SR2 with reference to colour table 20 gained.

Fig. 2 is the partial schematic diagram of the another kind of execution mode of displayed map 1.As shown in Figure 2, present embodiment is similar to the execution mode of Fig. 1, and difference is that first is arranged on the outer surface 12A of first platform 12 with reference to colour table 20, and second is arranged on the outer surface 32A of second platform 32 with reference to colour table 40.In this execution mode, first platform 12 and second platform 32 can be the platform or the local lighttight platforms of all printing opacities.First has gradually the structure of protruding with reference to colour table 20 and second respectively with reference to colour table 40, can cause the result of paper distortion because of protrusion suddenly to avoid file D, and then influence the execution of scanning operation.

It should be noted that the set-up mode of the reference colour table 20,40 of all right constitutional diagram 1 and 2.That is, first can be arranged on the outer surface 12A of first platform 12 with reference to colour table 20, and second can be arranged on the inner surface 32B of second platform 32 with reference to colour table 40.

The correcting sheet of known technology is arranged at the zone beyond the scan module, and the correcting sheet of ccontaining scan module and setting is come in the space that causes providing more in scanner.And in the utility model, reference plate (with reference to colour table) is arranged on the scan module, makes that the space of scanner is effectively utilized.By configuration of the present utility model, can effectively dwindle two spaces that scan module is shared, use the overall volume of dwindling scanner, meet the development trend of microminiaturization, lightweight portable electronic product.In addition, because the dwindling of the overall volume of scanner, thereby reduce employed material, and then reduce production costs and meet environmental protection requirement.

The specific embodiment that is proposed in the detailed description of preferred embodiment is only in order to convenient explanation technology contents of the present utility model, but not with the utility model narrow sense be limited to the foregoing description, in the situation that does not exceed spirit of the present utility model and following claim, the many variations of being done is implemented, and all belongs to scope of the present utility model.
