The present invention is a kind of filtering method and mechanism of optical scanner, and is main by in the manufacturing process of scanner, in conjunction with optical filter that is added and reciprocal gear train, makes optical filter can bring into play the effect that different optical filters filter on different opportunitys.
At first, see also the embodiment of the invention shown in Figure 2 adds optical filtering mechanism in light path mechanism synoptic diagram.The light path path of wherein being disclosed is mainly: two light sources are arranged, one is visible light source 20, another is an infrared light sources 30, both are separately emissions and be incident upon the file 10 of institute's desire scanning, reflex to first eyeglass 40 afterwards, reflex to second eyeglass 50, prismatic glasses 60 and the 4th eyeglass 70 etc. more in regular turn.Read image via camera lens (Lens) 80 more at last, close in the element (CCD) 90 and deal with and be sent to the electric charge lotus root.
The present invention has added in the light path path of optical filtering mechanism between file 10 and two light sources 20,30, and this optical filtering mechanism is by additive filter and reciprocal gear train.Wherein said reciprocal gear train includes: a motor 100, and in order to drive the reciprocating action of this optical filtering mechanism.One nut 102 is connected with connecting rod 106, is equipped with screw rod 104 in this connecting rod 106, further drives the to-and-fro movement of whole optical filtering mechanism by the rotation of motor 100.One screw rod 104 is placed among this nut 102, is connected with this motor 100 to rotate to cooperate.One connecting rod 106 in order to the optical filter that carrying is added, makes its energy to-and-fro movement.And the composition of described additive filter, include: first optical filter 108, in order to filter the wavelength of visible light source; Second optical filter 110 is in order to filter the wavelength of infrared light sources.
Seeing also in the embodiment of the invention shown in Figure 3 the synoptic diagram that further specifies of relevant optical filtering mechanism, mainly is to disclose the enlarged drawing in this optical filtering mechanism and be illustrated.Wherein the major function of this first, second optical filter 108,110 is in order to difference infrared light and visible light, and just this first optical filter 108 is in order to the light beyond the wavelength-filtered 400-700nm, keeps visible-range.And this second optical filter 110 is in order to the light beyond the wavelength-filtered 820-890nm, keeps the light of infrared wavelength range.By reciprocating type gear train, optical filter is switched back and forth afterwards, to accept 20, the 30 simultaneous emissions of two light sources of visible light and infrared ray.These two light sources can be visible light and the infrared ray modes of radiation at two places and simultaneously respectively, also can be that the mode that single fluorescent tube radiates two kinds of light sources is simultaneously implemented.
In addition, for reciprocal gear train of the present invention mainly is to reach the purpose that optical filter is back and forth pushed, its structure is formed except the aforesaid gear train such as motor 100 and screw rod 104, nut 102 (referring to Fig. 2, embodiment shown in Figure 3) connecting rod 106 that can be and is formed, and also can cooperate belt, cable wire, gear or tooth bar to do the variation of the different kinds of drive again.On the other hand, also can use the mechanism for implementing of electromagnetic switch 120 as reciprocating type transmission, as shown in Figure 4 be that another embodiment of the present invention uses electromagnetic switch 120 as driving the enforcement synoptic diagram that optical filter moves.It is different from embodiment shown in Figure 2, is to use electromagnetic switch 120 carrying out the reciprocating type transmission of this optical filtering mechanism, and carries first, second optical filter 108,110, uses to switch first, second optical filter 108,110.The first sheet 108 of this first filter is in order to filter the wavelength of visible light source; Second optical filter 110 is in order to filter the wavelength of infrared light sources.
Optical filtering mechanism proposed by the invention, its setting position can be on arbitrary position on the light path (comprise eyeglass (mirror), camera lens (Lens), electric charge lotus root and close element (CCD) or the like), and wherein this optical filtering mechanism shown in Figure 2 is that device is on the light path path between the scanning document 10 and first eyeglass 40.In addition also can be between eyeglass and camera lens with the optical filtering mechanism arrangement, as shown in Figure 5, this Fig. 5 is the enforcement synoptic diagram that in the embodiment of the invention lighting means is arranged on diverse location in the light path.Mainly be that this optical filtering mechanism (being to be reciprocating type gear train embodiment with electromagnetic switch 120) device is used and filtered visible light and two kinds of light sources of infrared ray in light path path between the 4th eyeglass 70 and camera lens 80.
See also a method flow diagram of the embodiment of the invention shown in Figure 6.When initial, open white light source and infrared light sources 200 simultaneously, movable base (Chassis) is enabled the white light optical filter to a certain fixed position 202, only allows white light pass through, and to scan 204, at this moment, the data after will scanning are simultaneously stored 206.The person of connecing enables infrared filter, only allows infrared light pass through, and scan 208 again, and the data after similarly will scanning is stored 210.After abovementioned steps 206,210 and 208, all be the operation of carrying out data processing 212 wherein; Be to add again the scratch data of desiring to try to achieve 214 are arranged and to be compared at the same time, as sweep signal foundation relatively.Comparison signal afterwards, the scratch of proofreading and correct former scanning patter partly 216.Judge whether to finish scanning 218? if finish, then finish; If do not finish, the movable base of then getting back to step 202 is so finished method of the present invention to a certain fixed position.Therefore, often separate emission in the prior art and obtain Different Light with visible light and infrared ray.And the present invention discloses another kind of use-pattern, makes visible light and infrared ray to launch simultaneously, and is separated with first, second light tiles.
In sum, the lighting means of a kind of optical scanner of the present invention can provide the one scan device can use visible light and the infrared ray mode as its scanning light source simultaneously, and is more to obtain, make powerful IPF.
