Embodiment
At first, scan method of the present invention is used a posting 1 (see figure 2), produce a printing opacity signal at scan start point, and when the end of scan, also produce a printing opacity signal, simultaneously when this transmission file 9 places this posting 1, in time the aforementioned initial printing opacity signal of shaded portions with stop the printing opacity signal, whether these signals of mat are partly covered and are distinguished whether this document 9 exists, with optionally scanning, utilize scanning machine to read above-mentioned signal simultaneously and determine its sweep limit automatically.
Wherein aforementioned printing opacity signal can be linear, shaped form or several dot signals, when if it is linear, when this transmission type file 9 places posting 1, this straight line printing opacity signal length promptly can because of the covering of this document 9 by brachymemma, so, can the signal section crested of mat straight line printing opacity and distinguish that whether this document 9 exists, if straight line printing opacity signal integrity, represent that then file 9 does not exist, otherwise, represent that then file 9 exists.Certainly, if aforementioned printing opacity signal point shape printing opacity signal, then the part point is capped, and part is printing opacity then, and all the other can reach same effect by that analogy.
In addition, the decision of file 9 sweep limits has dual mode in aforementioned scan method, and the first is provided with built-in document size default value when scanner is installed, and when judging that file 9 exists, directly gets (read range during scanning) with this default value frame; It two is to come the calculation document size with this initial printing opacity signal and the distance that stops the crested of printing opacity signal, and extrapolates the width that another axial required frame is got;
When scanning, after can scanning in advance, will scan the laggard line scanning of gained file 9 location records more in advance in mode of the present invention; If will save scan operation in advance, then when initial printing opacity signal crested, after reading interior build file 9 sizes, the beginning frame is got, after frame has been got All Files, (this moment is because the existing file size promptly to stop scanning, so do not need to stop the printing opacity signal), the single pass stroke is finished and is distinguished that whether file 9 exists and two operations of scanning like this, certainly, then can when initial printing opacity signal crested, begin frame and get, and when aforementioned termination printing opacity signal produces, stop frame and get when if scanner and operator interface therewith do not preestablish file 9 sizes and frame 90 thereof, can reach same effect, only the gained scanning result has frame 90; Have again, aforementioned default file 9 sizes operation also can by on this posting 1, be provided with for the operator interface therewith identification distinguish form 15 (see figure 2)s, and then produce one and distinguish and look the printing opacity signal, replacing user's setting operation, and have the effect of autoscan.
Have again, for knowing the position of finishing scanning, so move at last through locating to produce an end printing opacity signal at the corresponding scanning of posting optical track, this finishes the printing opacity signal must and stop the difference of printing opacity signal with aforementioned initial printing opacity signal, be beneficial to the end of scan and judge that scanner can be learnt the position of the end of scan like this.
The employed posting of the inventive method sees also Fig. 2, and this posting 1 comprises: a framework 10 is an opaque plate; The positioning seat 11 that one or more are located in the aforementioned framework 10 has a depressed part 110 and is nested with and locatees for the aforementioned transmission file 9 that conforms to its shape and size; One has the transparency window 12 that is a bit larger tham aforementioned transmission type file 9 is located in the aforementioned positioning seat 11, sees through this transparency window 12 and scans this document for scanner; And an equivalent is disposed at the mark 13 of aforementioned positioning seat 11, for light penetration, and can be when this document 9 be inserted positioning seat 11 shaded portions mark 13, all the other are light transmission state; Use this parts, method of the present invention is that this mark 13 of mat is partly covered by this document 9 opaque frames 90, makes the contraction in length of printing opacity mark, thereby judges whether this document 9 exists, and scans for you to choose.
The linear mark window 13 of aforementioned mark 13 in Fig. 2, offering, at this moment the printing opacity signal of Chan Shenging also is a linear printing opacity signal, can be same as preceding method scanning; Can end mark window 14 be set in this posting 1 corresponding scanning optical track scanning place at last again, finish the printing opacity mark to produce, this end mark window 14 is had any different with aforementioned start mark window 15 and end mark window, confirms to finish the position of scanning in order to scanner.
Secondly, be provided with a groove 111, be beneficial to this transmission file 9 and insert and take out in this positioning seat 11 sides extension; In addition, Fig. 3 illustrates second embodiment of the invention, and it makes several shape mark windows 13a with this mark, and it is inside and outside to be separately positioned on positioning seat 11, so that when this document 9 is inserted, the some shape mark window 13a that will be positioned at positioning seat 11 covers, and can be read automatically by scanner equally.
In addition, can see also in Fig. 1 a that this posting 1a is provided with through the place at first at the scanning optical track and distinguish form 15a for the light transmission, distinguish and look the printing opacity signal to produce one, and this distinguishes that form 15a changes according to the size of this positioning seat 11, type, distinguishes the size of looking file 9 automatically by scanner like this; Have again, in order to distinguish the size of looking file 9, can be by this mark window 13, spacing that 13a is capped calculates, the present invention is distinguished automatically look on the effect of file 9 and scanning has improvement.
Have again, for the scanning flow process of aforementioned second embodiment is described, please cooperate Fig. 3, it finishes the embodiment of scan operation for the single pass stroke, mainly read earlier and differentiate this and distinguish and look the printing opacity signal, this distinguishes mat and looks the size that the printing opacity signal is set transmission file 9, again pick up initial printing opacity signal, and whether differentiate this initial printing opacity signal complete thereafter, or the no file 9 of expression, or get according to the size row frame of aforementioned document 9, differentiate again afterwards whether to read and finish the printing opacity signal,, whether do not read initial printing opacity signal if obtain then differentiating again if obtaining this signal then finishes, get back to abovementioned steps again, can realize the aforementioned purpose of promptly finishing scan operation through single pass like this.
Have, the flow process of scan mode is close with the discriminant approach of Fig. 3 in advance again, and different is that it gets part with a batch mode record with the required frame of each file after scanning in advance, does mass scanning with this record value when scanning once more and finishes scanning work.
The present invention scans that optical track 99 moves and frame is got scope, sees also Fig. 4, and it is placed with four transmission file 9a in six positioning seats 11 are built-in, 9b, and 9c, 9d, and optical track 99 is represented with imaginary line, and progressively moving through whole framework 1, it moves situation and with differentiating to close is:
1. at first move after distinguishing form 15, the kind of promptly differentiating this framework 1 with read built-in positioning seat 11 sizes and need frame get scope 91 sizes and coordinate position;
2. move to a1 again, during the b1 horizontal level, promptly obtain initial printing opacity signal, and move to a2, during b2, learn the a2 crested and b2 does not have, represent promptly that a2 disposes to put file, get size and coordinate position and move on optical track 99 and carry out frame and get with the aforementioned frame of obtaining this moment immediately;
3. the continuous a3 that moves to, stopping the printing opacity signal during b3 position occurs, but owing to got the size of reading file 9, so stopping the printing opacity signal does not use, and then read initial printing opacity signal, and move to a4, the b4 position, promptly be b4 crested and a4 does not have this moment, so differentiate in the above described manner and frame is got acquisition file 9b again;
4. then read file 9c, 9d with said method again;
5. this optical track 99 moves to end mark window 14 thereafter, promptly stops scanning after reading this end printing opacity signal.
File 9a in the aforementioned flow process, 9b, 9c, the size of 9d, frame is got scope 91 and is all obtained by software after optical track 99 distinguishes to look this kind of distinguishing form 15 with coordinate position, in addition, also can work as optical track 99 distinguishes and only obtains file 9a when looking out this distinguishes form 15,9b, 9c, size and the frame of 9d are got scope, and just obtain coordinate position when optical track 99 moves to a2 point (crested of initial printing opacity signal), just carry out frame thereafter as previously mentioned and get, this moment, this a2 point was whether file 9a exists and the reference point of coordinate position, and this reference point all has at each positioning seat 11 place and is beneficial to distinguish and looks certainly.
Certainly in aforementioned flow process, if remove end mark window 14, then scanning motion in advance need be arranged, with the initial and end position of certain affirmation scanning.
In sum as can be known, method of the present invention and posting 1, the use of 1a can realize purpose of the present invention, and right aforementioned embodiments of the invention can not limit the present invention, and feature of the present invention is included in claims of the present invention.
