Existing image scanning system, is normally being installed light source by above the side of scan image.As shown in Figure 1, this image scanning system comprises CCD (Charge-coupled Device, image controller.) 11 and multiple speculum 12 and the light source 14 be located at above by scan image 13 side.This light source 14 for by scan image emission of light to illuminate by scan image.This light source 14 and scan line shape in an angle, when as shown in Figure 2, during by scan image as bank note out-of-flatness, due to light source 14 be not directly over, at R place formation shade, the definition of scan image will be affected.
Summary of the invention
In view of this, the purpose of this utility model is to provide a kind of image-scanning device light source and image scanning system, to solve the problem that existing light source easily forms shade.
Based on above-mentioned purpose, the utility model embodiment provides a kind of image-scanning device light source, and described light source comprises at least one first luminescence unit be located on described image-scanning device, for by scan image emission of light.
Preferably, described first luminescence unit is symmetrically set on described image-scanning device.
Preferably, described first luminescence unit is dismountable is located on described image-scanning device.
Preferably, described first luminescence unit is LED lamp bead.
Preferably, described image-scanning device is CCD.
Preferably, described first luminescence unit is located at the side and/or and/or below of described image-scanning device above.
Preferably, described light source also comprise be located at described by the second luminescence unit above scintigram image side.
The utility model embodiment is also done on the other hand and is provided a kind of image scanning system, comprises image-scanning device, speculum and above-mentioned image-scanning device light source;
Described image-scanning device, for scanning by scan image;
Described light source, for described by scan image emission of light;
Described speculum, for by described light reflection to described by scan image and by the described light reflection reflected by scan image to described image-scanning device.
Preferably, described first luminescence unit is located at the side and/or and/or below of described image-scanning device above.
Preferably, described light source also comprise be located at described by the second luminescence unit above scintigram image side
Beneficial effect:
The utility model, by being arranged on image-scanning device by light source, makes no matter by scan image whether out-of-flatness, light be all directly over it according to, and then to ensure that by the impact of scan image not light shade.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1,2 is image scanning system structure chart in prior art;
Fig. 3, the 4 image scanning system structure charts provided for the utility model embodiment.
Embodiment
For making the object of the utility model embodiment, technical scheme and advantage clearly, below in conjunction with the accompanying drawing in the utility model embodiment, technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
The utility model embodiment aims to provide a kind of light source of image-scanning device, this light source is located on image-scanning device, the light that light source is sent is forever all by directly over scan image, thus, no matter whether smooth by scan image, all there will not be the phenomenon of time shadow, thus ensure that the definition of scan image.
As shown in Figure 3,4, be a kind of image-scanning device light source that the utility model provides, this light source comprises the first luminescence unit 24 (34) be located on image-scanning device 21 (31), for emitting beam.This light impinges perpendicularly on by scan image 23 (33) after speculum 22 (32) is launched.Because the first luminescence unit is located on image-scanning device, the light penetrated can be mapped to by scan image by the scanning optical path of image-scanning device.
Fig. 3 and Fig. 4 respectively illustrates and out-of-flatness two states smooth by scan image.Can go out from figure, no matter whether smooth by scan image, the light that the first luminescence unit sends all is penetrated from by directly over scan image, thus avoids and occur time shadow phenomenon, ensure that the definition of scan image.
It should be noted that, if the first luminescence unit is located at the top of image-scanning device, then image-scanning device can stop at least part of light of the first luminescence unit injection.If the first luminescence unit to be located at the below of image-scanning device, then the scanning optical path of image-scanning device can be stopped by the first luminescence unit.Therefore, in preferred embodiment of the present utility model, the first luminescence unit can be located at two sides, the front and back of image-scanning device.Namely the vertical paper shown in Fig. 3,4 inwards, vertical paper outwards, the position at front and rear.
In the utility model, the first luminescence unit is connected to image-scanning device by dismountable mode.
In addition, for ensureing uniform light, multiple first luminescence unit can be symmetrically set on image-scanning device.
Certainly, the second luminescence unit be positioned at above by scintigram image side can also be set in the utility model simultaneously, make it work together with the first luminescence unit, ensure the definition of scan image.
That above-mentioned image-scanning device is concrete can be CCD, and luminescence unit is specifically as follows LED lamp bead.
Below be only preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection range of the present utility model.
