Introduce preferred embodiment below in detail
At first with reference to Fig. 1, reference number 10 expressions are constructed with the identification that the electro-optic scanner that scan light is scanned along a sweep trace at least uses.Be suitable for this purpose electro-optic scanner from United States Patent (USP) the 4th, 387, No. 297, the 4th, 409, No. 470, the 4th, 816, No. 660, the 4th, 896, any one in No. 026 can find.These United States Patent (USP)s have all transferred the application's assignee.The full content of these United States Patent (USP)s is all quoted in this article as the reference data.
Above-mentioned United States Patent (USP) is is all recorded and narrated as an embodiment the portable scanning head that light source (preferably gas laser or semiconductor laser) is housed respectively at least.For forming light beam spot, the light that light source is sent used optical element.Light beam spot can be positioned at the outside near probe, also can be positioned at apart from the desired distance in there.Scanning element makes light beam spot scanning form sweep trace.The operator places sweep trace on the mark that will scan.The light of reflected back is detected by the photodetector in the probe from the mark.Photodetector produces the analog electrical signal of expression by the varying strength of the light of the different photo-emission part sub reflectors of mark.This analog electrical signal is converted into digitized signal, deciphers according to the algorithm of memory stores then.These all carry out under the control of the microprocessor of programmed.Signal through deciphering is identification sign uniquely, can exist in the probe, also can deliver to principal computer and go, and this mark promptly is read like this.
According to a feature of the present invention, will be used for attached purpose with scanner same shown in the label among Fig. 2 12, promptly be used to discern, catch the mark 14 that is arranged on space 16.What mark 14 and UPC mark were such can be different with the coded markings of machine recognition.Mark 14 as described herein is idiographs as shown in fig. 1.Certainly, doing like this is for convenience of explanation because the present invention is not limited only to catch hand-written signature, can be used for catching other figure too or affix one's seal or the signature printed or other all kinds of as marks such as impression of the hand, symbol, mark, little chapters.There are boundary line 18 and 20 in space 16 in vertical rear and front end.Best (but be not necessary) space 16 with the above-mentioned vertically vertical two side lines 22 and 24 that are spaced laterally apart a segment distance that transversely have.As shown in the figure, the planimetric map in space 16 is rectangular, also can consider other shapes.In preferred embodiment, boundary line 18 and 20 distance are about 2.7 inches (6.86 centimetres), and boundary line 22 and 24 distance are about 0.4 inch (1.02 centimetres).
The occupied area, the light reflectivity in the zone of the part that promptly bears the signature does not promptly have the area light reflectivity of signature section different with the unoccupied zone.The bar of occupied area and upc bar code is similar, but not the occupied area is then similar with the blank parts of upc bar code." 1 " in the scale-of-two is represented in the occupied area, but not " 0 " in the scale-of-two is then represented in the occupied area.When the sweep trace of scanner 12 was passed by delegation zone in the space, the light of occupied area reflection was less than the light of unoccupied regional reflex.The optical information of this variation can be represented the data of signing with being processed into the method for handling UPC mark all fours.
But the UPC mark is an one dimension, if at arbitrary place of its short transverse (being horizontal Y-axis) by sweep trace scan just can read data; And the mirror name has comprised vertically (X-axis) and the laterally information of (Y-axis) both direction, is two-dimentional.In order to reproduce the signature of two dimension, need also to know which row zone a certain specific sweep trace is scanning, and when each sweep trace enters and leaves and contain the space that bears the signature.
The present invention builds justice, and 16 front and back ends (longitudinally considering) is provided with multirow top end stops device 26 and multirow rear end sign indicating number device 28 respectively in the space.Each yard device is the multirow mark structure, be provided with can by electropical scanning and read longitudinally with transversely arranged coded data.Each mark structure can be a unique two-dimensional marker structure, as bar code or new mark structure compatible mutually with popular standard bar code structure of a branch.Before a kind of being applicable to, the multirow bar code of rear end sign indicating number device 26,28 is at United States Patent (USP) the 4th, 794, discloses in No. 239, and its content is here quoted as a reference, also please refer to Fig. 6.
Each end sign indicating number device 26,28 is arranged at a plurality of row longitudinally 1,2,3,4 with its coded data ... on the N, wherein, N is the enough big numerical value of the preferable sharpness that can obtain signing.In theory, when line number is unlimited, can provide best sharpness, as long as but in fact have 25 row just can obtain the signature of suitable sharpness.These row are to arrange layer by layer successively in the horizontal.
Each row of coded data comprises that one is used to judge that a special time one scan line is scanning the capable recognition device of that delegation.As shown in Figure 1, with regard to horizontal scanning line 30, end sign indicating number device 26,28 capable recognition device separately comprises that identifying the row that this moment scanning is the 3rd capable data.Still as shown in Figure 1, with regard to dip sweeping line 32, the capable recognition device of top end stops device 26 comprises that identifying the row that this moment scanning is the data of the 1st row, and the capable recognition device of rear end sign indicating number device 28 comprises that identifying the row that this moment scanning is the 2nd capable data.
Each coded data row also comprises and is used to judge the pass by synchronous device in front and rear side boundary line in space 16 of each sweep trace when, promptly begins/stop data.
At first make scanner 12 produce a sweep trace (as sweep trace 30) with the inswept identification structure 10 of zero drift angle level during use, that is, and the pass by same delegation of top end stops device and rear end sign indicating number device of same sweep trace.Sweep trace 30 overscanning identification structure 10.For example, the linear sweep of one 4 inches (10,6 centimetres) is enough to cover the length in top end stops, rear end sign indicating number device and space 16.Overscanning helps to reduce the inhomogeneous of sweep trace two ends light beam spot speed.
With the top that scanner 12 places identification to construct, then, the operator is lower than identification structure by the identification structure up to it with the horizontal motion scan device of hand.In the manual transfer process, have mutually colleague's number front end capable with the rear end row by identical sweep trace scanning, each successively is scanned corresponding row.Scanner 12 with photodetector detect the variation light intensity that occupied area in top end stops, the space and unoccupied zone and rear end sign indicating number are reflected.As shown in Figure 1, for the 3rd sweep trace 30 of going of each fore device of passing by, rear end sign indicating number device, signature 14 is represented an occupied area with the point of crossing of sweep trace 30, and signature 14 is represented the unoccupied zone with all Uncrossed points of sweep trace 30.
Electric analoging signal corresponding to each end sign indicating number device and occupied area, unoccupied zone is produced by photodetector.These simulation signals are deciphered according to an algorithm under the control of little processing by simulation/digital quantizer digitizing.Decoded signal is deposited in the storage unit.The signal of being stored can be retrieved from storage unit, thereby signature can form on display screen or printer again.
In fact, sweep trace can not accurately be placed identification textural and make the identical row of the inswept front and back ends sign indicating number of sweep trace device.Usually, sweep trace shows non-zero slope and tilts shown in representative parallax 32.However, with method similar to the above, scanner 12 places the mark top, and moves along horizontal lower position to mark with hand.The front end of each sweep trace is capable, the rear end row is by record respectively, because the size in space 16 is scheduled to, thereby can calculate slope.Like this, with regard to each sweep trace, just know it, occupied area and unoccupied zone on the rear end of space every trade number and this sweep trace through the front end every trade of space number.All these information all are stored in respectively in the storage unit, can retrieve as required and on the display screen and printer on reconstituting mark.
Can be not yet with scanner manual transfer in the horizontal, and make sweep trace itself automatically along the scanning of " Y " axle.For example, the output of scanner can not be above-mentioned single sweep trace, the raster mode that can form with the sweep trace that is parallel to each other by a group.For example, can be with reference to United States Patent (USP) the 4th, 816, No. 661.The full content of this United States Patent (USP) is all here quoted as the reference data.
Scanner 12 can be used manual manipulation, place away from the place that will scan mark (with reference to Fig. 2) in the mode that does not contact with the identification structure, perhaps under the situation of using identification pen 34, (with reference to Fig. 3) is arranged on scanner facing to the place of discerning structure with the way of contact.Also can be set as scanning workbench 36, the own stationkeeping of scanister and need not to move (referring to Fig. 4), identification structure 10 moves with respect to scanning workbench 36.For example, will discern structure 10 transmits by stationary work-table 36 by travelling belt 38.
As shown in Figure 5, be printed on identification structure 10 on the tracking tags 40, and contain the tracking that to form by the multidigit number by arabic numeral of people's identification numbers 42 on the label 40.Label 40 also contains UPC mark 44, and it is can be by the mechanical-readable numeral of electro-optic scanner identification, it can be decoded as to follow the tracks of numbers 42.The place 46,48 of also containing the weight of filling in the article 50 that to send by post on the label and transporting number.Label 40 has the pressure-sensitive back side of gluing usually, and this back side is in order to be attached on the mail 50.Also this label can be inserted in the pocket that is fixed on reliably on the mail 50.
As Fig. 2-shown in Figure 4, when being attached to label 40 on the mail 50, use as 12,34,36 scanner can read top UPC mark 44 with general fashion.Simultaneously or then, can read identification structure 10, have the space 16 that is filled with signature 14 on it with scanner.
The signature capture feature of confirming the mail receiptor more than has been described, but has also had other very wide purposes of coverage.For example, in the electronic lock purposes, sample is checked and approved signature pre-deposits in the storer, to later signature carry out optically read and with former sample signature relatively, whether consistent according to both, allow or do not allow near shielded place.Here said protected place can be meant place or automatic payment machine, automatic machine etc.
Top end stops device 26 and rear end sign indicating number device 28 differ and address above the fixation on the front and back that are arranged on the 16 vertical meanings of space shown in Figure 1.End sign indicating number device 26,28 also can be arranged on space 16 upper and lower transversely.Perhaps, with each multirow sign indicating number device be arranged on the preceding of space 16 and after, upper and lower, promptly on all 4 borders, catch signature 14 or other similar images at the vertical and horizontal both direction.
Fig. 6 represents actual end sign indicating number device 26 or 28 preferred embodiment.This end sign indicating number device is a two dimension, and 16 row are arranged, and this can provide catches the enough sharpness of image.
Be understood that, above-mentionedly respectively constitute in the unit, or two or more formations unit, with above-mentioned dissimilar image forming mode in also be of great practical value.
The present invention is to have made diagram and to be illustrated of the signature capture of electropical scanning, still, the present invention is not limited only to illustrated content.According to spirit of the present invention, can also carry out various corrections and structure change.
