Description
Technical field
The improvement that the present invention relates to extract the trace of seal and be registered as the print input device of numerical data.
Background technology
In general, when registering, the seal that speckles with ink paste is impressed on the paper, and this paper is scanned with optical scanner at the trace that extracts seal and with digital data form, thus the trace of extraction seal.But, when this method of employing, can make the profile width difference because of the increase and decrease of ink paste adhesion amount or can produce infiltration etc., even its result uses same seal, also differing obtains identical shade surely, thereby not satisfactory.And, owing to need wait until the scan operation of carrying out optical scanner after the paper drying that is attached with ink paste again, therefore register seal required in case of necessity between be difficult to shorten.In addition, also there be the problem of waste as the paper of intermediate medium.
On the other hand, the trace that extracts seal is disclosed in the patent documentation 1 below under the situation of not using paper and as the invention of numerical data registration, promptly, on optical scanner, be arranged on the pressure-sensitive thin plate of temporary transient variable color when being subjected to pressing force, and when depressing the front end of seal, read in the part that produces variable color on the pressure-sensitive thin plate, be transformed to numerical data with optical scanner.Such invention has become known technology.
But,, must get rid of the pollution of the pressure-sensitive thin plate that disturbs for read the variable color part of look exactly from the pressure-sensitive thin plate.Thereby the ink paste that must wipe the seal front end neatly is again to pressure-sensitive thin plate impression, and its result produces the become problem of trouble of the pre-treatment relevant with cleaning seal.In addition, if produce breakage etc. on the pressure-sensitive thin plate, then the optical index of this part will change, and there are the restriction that must operate the pressure-sensitive thin plate extremely carefully in the variable color part that might be look with this breakage wrong identification, its result.
In addition, the trace that extracts seal is disclosed in the patent documentation 2 below under the situation of not using paper and as another invention of numerical data registration, that is, the front end face of the seal that is provided with by transparent guides (guide) from being situated between reads trace in the noncontact mode.
Yet, in above-mentioned technology, must use the reading devices such as for example optical reading device that detect the front end shape of seal in the noncontact mode, and because the front end face that seal may take place can't be extracted the situation of trace exactly by pollution such as ink paste, therefore still there is the problem that will carry out as the pre-treatment of seal cleaning, thus not satisfactory.
[patent documentation 1] spy opens flat 4-247584 communique (paragraph sequence number 0004);
The clear 61-290580 communique of [patent documentation 2] special hope (second page of upper left hurdle 14 row～16 row).
Summary of the invention
The present invention is in view of the above fact, its purpose is to provide a kind of following print input device, promptly improve the not convenient aspect of above-mentioned conventional art, do not need to adopt intermediate mediums such as paper, and do not need to carry out cleaning operation, thereby can extract the trace of seal and the print input device of registering in the numerical data mode at short notice exactly.
The invention provides a kind of print input device, it is used to extract trace that is engraved on the seal and the print input device of registering as numerical data, and in order to address the above problem, it is characterized in that possessing: profile testing agency, it is integrated into small induction region on the roughly same plane and forms, wherein, described small induction region is in the abstraction process of trace, stimulates the zone that output is changed according to the physical property from the outside that changes based on having or not of seal leading section; Decision mechanism, it reads the output of each induction region of the described profile of self-forming testing agency, described output and predetermined conditions are compared, when described condition is set up, judge in this induction region, to have detected the seal leading section, in this induction region, do not detect the seal leading section and when described condition is false, be judged to be; Trace digitizing mechanism, it is based on the arrangement of the induction region in the described profile testing agency and the result of determination that is drawn by described decision mechanism, on two-dimensional matrix to distribute the mode that whether has the seal leading section to constitute the numerical data of trace.
According to above structure, being on the roughly same plane of profile testing agency and the small induction region separately of configuration, in the abstraction process of trace, detecting the physical property from the outside that changes based on whether having the leading section of seal stimulates the signal that output is corresponding with this stimulation.
Being determined mechanism from the signal of each induction region output of profile testing agency reads, and this decision mechanism, to compare from the signal and the predetermined conditions of the output of each induction region, when described condition is set up, be judged as and in this induction region, detected the seal leading section, in this induction region, do not detect the seal leading section and when described condition is false, be judged as.For example, if the physical property from the outside that changes based on whether having the leading section of seal stimulates and the output signal of change, be to be below the setting more than the setting and when not having the leading section of seal when having the leading section of seal, then this setting can be set at threshold value, and use output signal and described threshold value to compare from each induction region, when output signal be threshold value be judged to be when above detect the seal leading section and when output signal be that threshold value is judged to be when following and does not detect the seal leading section.
Finally, trace digitizing mechanism is based on the arrangement of the induction region of profile testing agency with according to the result of determination of decision mechanism, on two-dimensional matrix, construct the front end shape of seal again, and make the numerical data of trace thus in the mode of distributing the leading section that whether has seal.
As previously discussed, owing to being utilizes small induction region is integrated into the profile testing agency that forms on the roughly same plane and the front end shape of Direct Recognition seal, therefore accurate trace, i.e. the front end shape of seal extracted under the situation about staining of seal front end face can not related to.
In addition, but because the front end shape of this profile testing agency Direct Recognition seal, the intermediate medium of paper etc. that therefore can not need the front end shape of transcription seal, therefore can extract trace not relating under the situation about staining of seal front end face, thereby also need not clean loaded down with trivial details work such as seal in advance.
More particularly, described profile testing agency is made of the pressure transducer group of a plurality of pressure transducers of set, wherein, described a plurality of pressure transducer, performance makes the function of the small induction region of output change according to the suffered pressure of leading section of the seal that is pressed in the abstraction process of trace
And whether described trace digitizing mechanism can exist the mode of seal leading section to constitute according to distributing in the two-dimensional matrix on storer.
Using under the situation of this structure, if in the trace abstraction process, push the seal front end to profile testing agency, each pressure transducer of the small induction region of conduct of the profile testing agency that constitutes by the pressure transducer group output signal respectively then.This signal is according to being pressure based on the stimulation from the outside that whether has the seal leading section to change in the abstraction process of trace, and the signal that changes.
Same as described above, by decision mechanism the signal of exporting from each induction region (each pressure transducer) of profile testing agency (pressure transducer group) is read, this decision mechanism will compare from the output and the predetermined conditions of each induction region, and when condition is set up, be judged as and in this induction region, detected the seal leading section, in this induction region, do not detect the seal leading section and when described condition is false, be judged as.
And, final trace digitizing mechanism is based on the arrangement of the induction region (pressure transducer) of profile testing agency (pressure transducer group) with according to the result of determination of decision mechanism, on the two-dimensional matrix on the storer, construct the front end shape of seal again, and make the numerical data of trace thus in the mode of distributing the leading section that whether has seal.
Also have, as not using intermediate mediums such as paper and not relating to staining of seal front end face and the profile testing agency that can extract the front end shape of seal exactly, except utilizing the mode of the pressure that produces by direct contact seal leading section, it is also conceivable that the mode that is used in combination following two parts that adopts, i.e. hyperacoustic output mechanism that the stone material that constitutes seal etc. is reflected easily and the reflection wave testing agency group that is divided into small form by ink paste isocolloid shape material.But, consider not limit front end shape and the simplified construction that the imprinted material mode that becomes the extraction of trace object can detect seal exactly, here be to have used the pressure transducer group (only otherwise this problem of being considered to as profile testing agency, with present technical merit, can realize the profile testing agency that the pressure transducer group is outer).
Under situation, preferably absorb the microdeformation of seal leading section and the pressing force of seal is conveyed to the pilot thin plate of described pressure transducer group in the surface coverage of pressure transducer group as profile testing agency working pressure sensor groups.
Though sometimes by wearing and tearing of seal etc. and make the seal front end face may not exclusively be on the plane, but by surface coverage pilot thin plate in the pressure transducer group, can absorb the microdeformation of seal leading section, and will be conveyed to the pressure transducer group, and then can obtain the Exact Number data corresponding to the pressing force of each one of front end of seal front end shape.
Wherein, the pilot thin plate preferably is made of the material that possesses enough elasticity and toughness for protection pressure transducer group.
Thus, can prevent the damage of the pressure transducer group that causes by the collision of seal or an end in contact etc. in when impression, improve the permanance of device integral body by the pilot thin plate.
In addition, the supporter that supports described pressure transducer group can also be set, also availablely can keep this supporter in the damping of shocks mechanism of pressurized direction displacement.
Under the situation that adopts this structure, before the unaffordable excessive external force of described pilot thin plate acts on the pressure transducer group, the supporter of abutment pressure sensor groups self is towards the displacement of pressurized direction, and with damping of shocks mechanism absorption in the external force of pressure transducer group, thereby prevent the damage of pressure transducer group.
As damping of shocks mechanism, for example can utilize with the volute spring that can keep supporter or oil damper etc. at the state of pressurized direction compression.
In addition, the supporter that supports described pressure transducer group can be set, and keep this supporter by stance adjustment mechanism.
Owing to supporter is to constitute in the mode that the front end face that allows to copy seal changes posture, seal one end in contact in the time of therefore can suppressing to impress etc. make the front end face press pressure sensor groups exactly of seal.
As stance adjustment mechanism, for example can utilize the volute spring of the posture change that allows supporter or oil damper etc.
And, can also dispose the damping of shocks stance adjustment mechanism of common permission towards the variation of the displacement of the pressurized direction of supporter and posture.
Because the supporter self that allows abutment pressure sensor groups before excessive external force acts on the pressure transducer group is towards the displacement of pressurized direction, also allow supporter that posture is changed in addition, one end in contact phenomenon of seal in the time of therefore can effectively suppressing the damage of pressure transducer group and impression.
As damping of shocks stance adjustment mechanism, for example can utilize with the volute spring that can supporter be kept by the mode that can change posture at the state of pressurized direction compression or oil damper etc.
In addition, utilizing as profile testing agency under the situation of pressure transducer group, except described each formation, following mechanism can also be set simultaneously: clamping device, it keeps seal with the front end of the seal state with respect to described profile testing agency by dismountable mode; Seal connects from travel mechanism, in its relation between described profile testing agency and described clamping device, either party is connect from moving with respect to the opposing party; And control part, it drives described seal and connects from travel mechanism up to the front end of seal with set pressure with after described profile testing agency docks, described profile testing agency, described decision mechanism and described trace digitizing mechanism are started working, and the numerical data on the described storer is outputed to epigyny device.
Be suitable under the situation of this structure, can realizing the obtaining of numerical data of trace in the robotization mode.
Promptly, if keep seal and move control part with clamping device, then at first seal connects from travel mechanism according to the mode that is docked to profile testing agency up to the front end of seal by set pressure, be driven according to instruction, push the seal front end to the profile testing agency that constitutes by the pressure transducer group from control part.
Then, the profile testing agency that will constitute by the pressure transducer group, decision mechanism and trace digitizing mechanism start working in proper order by this, and with decision mechanism to reading from signal as each pressure sensing zone output of small induction region, and will compare from the output signal and the predetermined conditions of each induction region by this decision mechanism, whether judgement detects after the seal leading section in each induction region, trace digitizing mechanism is based on the arrangement of the induction region (pressure transducer) in the profile testing agency (pressure transducer group) and the result of determination of above-mentioned decision mechanism, the mode that on the two-dimensional matrix of storer, whether has the leading section of seal with distribution, construct the front end shape of seal again, and make the numerical data of trace thus.
And Jie of the numerical data on the storer transfers to epigyny device by control part the most at last.
According to above structure, owing to can often push the seal front end to profile testing agency with set pressure, therefore can carry out stabilization to the size of exporting from the signal of each pressure transducer that constitutes the pressure transducer group, its result can very correctly judge whether there is the seal leading section on each induction region, and then further improves the reliability as the numerical data of the final trace of exporting.
Be provided with at the same time under the situation of such control part, preferably make described profile testing agency, decision mechanism, trace digitizing mechanism repeatedly work, and will exist the information of seal leading section temporarily to store in the two-dimensional matrix on storer with the disjunctive form formula.
Owing to extract seal front end shape through repeatedly working by profile testing agency and decision mechanism, and will exist the information of seal leading section temporarily to store in the two-dimensional matrix on storer with the disjunctive form formula, even therefore exist by once extracting operation can not the situation of detected shape under, also can improve the possibility of the front end shape at this position of extraction in the extraction operation that other times are carried out.
Thereby, and only when extracting seal front end shape, operation compares by once extracting, can significantly improve reliability as the numerical data of the trace of final output.
In addition, can also make control part possess automatic retray function, wherein, described automatic retray function, be meant the logic that has the seal leading section in the two-dimensional matrix that temporarily is stored on the storer and surpass during the setting value function that profile testing agency, decision mechanism, trace digitizing mechanism are worked repeatedly.
Under the situation that is suitable for this structure, till the total area of the front end shape of seal reaches setting value, promptly till the reliability of the numerical data of trace is guaranteed MIN degree, extract seal front end shape repeatedly by profile testing agency and decision mechanism, therefore, with only by once extract operation when extracting seal front end shape or the number of times that will extract operation be set at and compare when fixed value is extracted seal front end shape again, can further improve reliability as the numerical data of the trace of finally exporting.
In addition, can also make control part possess automatic return function, wherein, described automatic return function, connect from travel mechanism even be meant at the driving seal, the seal front end is docked under the situation in the profile testing agency with authorised pressure, perhaps, even make profile testing agency, decision mechanism, trace digitizing mechanism temporarily is stored in the logic that has the seal leading section in the two-dimensional matrix on the storer and is no more than under the situation of setting value when working repeatedly, the output error signal, and reverse to drive seal and connect from travel mechanism, seal is kept apart from profile testing agency.
By being suitable for this structure, do not make the seal front end can't accurately be docked under the situation of profile testing agency on the clamping device owing to correctly being installed in when seal, perhaps, fail accurately to extract under the situation of trace of seal, seal is connect from travel mechanism reverse driving automatically, and then clamping device is back to position of readiness, therefore can accurately prevent to handle the generation of the abnormal ending of operation.
Thereby, print input device can be arranged on the paving and the use-pattern that the user is used voluntarily, perhaps, by showing the setup error of seal based on error signal or reading in wrong generation and then impel the user to take the mode of retry operation through judgement.
Print input device of the present invention, small induction region is integrated on the roughly same plane and forms profile testing agency, wherein, described small induction region, be in the abstraction process of trace, stimulate according to the physical property that changes based on having or not of seal leading section, make the zone of output change from the outside; And read the output of each induction region of the described profile of self-forming testing agency, and judge in each induction region, whether to detect after the seal leading section, based on the arrangement of the induction region of the result of determination of decision mechanism and profile testing agency, on two-dimensional matrix, generate the numerical data of trace again in the mode of distributing the leading section that whether has seal.Therefore, can not need to use the transcription seal the front end shape intermediate medium such as paper and can extract the front end shape of seal when not relating to the staining of seal front end face exactly.

Embodiment
Below, illustration preferred forms of the present invention.Fig. 1 is the deep cutting view that an example of using print input device of the present invention is simplified expression.
The major part of print input device 1 shown in Figure 1 is made of the pressure transducer group 2 and the translation circuit 3 of performance as profile testing agency function.
Wherein pressure transducer group 2 is profile testing agencies, it is integrated into pressure transducer 4 on the roughly same plane and forms, and described pressure transducer 4 performances make the function of the small induction region of output change as a kind of pressure that stimulates according to the physical property from the outside.And as shown in Figure 2, described pressure transducer group 2 is by constituting a plurality of pressure transducers 4 with the two-dimensional-matrix-like configuration.
In addition, as shown in Figure 3, translation circuit 3 possesses: decision mechanism 6, it reads the output of each pressure transducer 4 of self-forming pressure transducer group 2, should export with predetermined conditions and compare, and under the situation that predetermined conditions has been set up, be judged to be the leading section that in this pressure transducer 4, has detected seal 5, under the invalid situation of predetermined conditions, be judged to be on the other hand and in this pressure transducer 4, do not detect seal 5 leading sections; Storer 8a, frame memory of the image that it is formed by the numerical data of black and white 2 gray scales by temporary transient storage etc. constitutes; Trace digitizing mechanism 7, whether it exists the mode of seal 5 leading sections to constitute the numerical data of trace with distribution based on the arrangement situation of the pressure transducer in the pressure transducer group 24 and the result of determination that is drawn by decision mechanism 6 in two-dimensional matrix on storer 8a.
Be provided in decision mechanism 6 judging whether pressure transducer 4 detects the threshold value of the pressure that is acted on from seal 5, for example, when the common power of pressure transducer group 2 usefulness is pushed seal 5, when the output signal of the pressure transducer 4 of the projection of promptly carving from the part that is positioned at the leading section that has seal 5 is set to X1, the output signal of the pressure transducer 4 of the sunk part of promptly carving from the part that is positioned at the leading section that does not have seal 5 is set to X2, then for example can set the threshold to their intermediate value (X1+X2)/2.
Here, suppose X1＞X2, then when being that (X1+X2)/2 are when above from the signal of pressure transducer 4 output X, be judged to be the existence of the leading section that in this pressure transducer 4, has detected seal 5, the i.e. existence of Diao Ke projection, in addition, if be (X1+X2)/2 when following, be judged to be the existence of the sunk part that in this pressure transducer 4, has detected the engraving in the seal 5 from the signal of pressure transducer 4 output X.
In the present embodiment, because the arrangement of the pressure transducer 4 in the pressure transducer group 2 is two-dimensional-matrix-like, and the memory location of each pixel of the two-dimensional matrix on the storer 8a is corresponding in fact one by one with the arrangement of pressure transducer 4, therefore as shown in Figure 3, can make trace digitizing mechanism 7 simply based on the result of determination of decision mechanism 6, on the correspondence position on the storer 8a, distribute the leading section that whether has seal 5.Promptly when being that (X1+X2)/2 are when above from the signal of pressure transducer 4 output X, to be set at black to the pixel of position that should pressure transducer 4, and when from the signal of pressure transducer 4 output X being (X1+X2)/2 when following, will be set at white to the pixel of position that should pressure transducer 4.
But the arrangement of the pressure transducer 4 in the pressure transducer group 2 might not be two-dimensional-matrix-like.When the arrangement of the pressure transducer in the pressure transducer group 24 is different under the situation of the two-dimensional matrix on the storer 8a, arrangement based on the pressure transducer in the pressure transducer group 24, obtain the arithmetic expression of the configured corresponding relation of the two-dimensional matrix on specified pressure sensor 4 and the storer 8a in advance, and this arithmetic expression stored in the trace digitizing mechanism 7, and trace digitizing mechanism 7 distributes the leading section that whether has seal 5 according to this arithmetic expression in the two-dimensional matrix on storer 8a.
In the abstraction process of trace, if push the front end of seal 5 to pressure transducer group 2, then promptly carve having or not of protuberance according to the having or not of leading section of seal 5, the pressure that change stimulates as the physical property from external action on each pressure transducer 4 of pressure transducer group 2, and change from the signal of each pressure transducer 4 output X according to this pressure, therefore by this signal output X and described threshold value (X1+X2)/2 are carried out the comparison of magnitude relationship, respective signal is exported X be set at black for the pixel of the position of the above pressure transducer 4 in (X1+X2)/2, and respective signal is exported X be set at white, thereby the numerical data of trace is formed on the storer 8a for the pixel of the position of the following pressure transducer 4 in (X1+X2)/2.
Consider the contrast precision of trace etc., the configuration density of the pressure transducer 4 in the pressure transducer group 2 is preferably more than the 240DPI.
In the print input device 1 of this embodiment, as shown in Figure 1, also on the surface of pressure transducer group 2, cover pilot thin plate 9, it is used to absorb the microdeformation of seal 5 leading sections, and pressing force is delivered on the pressure transducer group 2.
As the material of pilot thin plate 9, preferably possesses the material of enough elasticity and toughness from the angle of protection pressure transducer group 2.And in this embodiment, the sealing gasket (Seal) of the silicon materials system about having used thickness as 0.5mm, under the situation of deteriorations such as producing damage on the pilot thin plate 9 or stain, can peel off pilot thin plate 9 from pressure transducer group 2 simply, new pilot thin plate 9 is installed again.
With reference to Fig. 4, the principle of work of pilot thin plate 9 is described here.Fig. 4 (a) is the cut-open view of an example that the expression leading section has the seal 5 of microdeformation.In this embodiment, on the part of the engraving protuberance of seal 5, change and wait and form wear 5b, thereby between the 5a of appearance profile portion of the front end of seal 5 and wear 5b, formed difference in height through the time.
With ink paste attached to seal 5 on and when being stamped on the paper, shown in Fig. 4 (b),, therefore can fill the gap between this ink paste 10 and the paper 11 owing on wear 5b, be attached with enough ink paste 10, obtain correct trace.
But, if not on seal 5, adhering to ink paste, but on pressure transducer group 2, carrying out coining manipulation under the situation that does not adopt pilot thin plate 9, then between the surface of wear 5b and pressure transducer group 2, can produce the gap shown in Fig. 4 (c), and then may produce the unfavorable condition that the locational pressure transducer 4 relative with wear can't detect the part of engraving protuberance.
Therefore, for addressing this problem, in this embodiment, shown in Fig. 4 (d), covering pilot thin plate 9 absorbs the microdeformation of the leading section of seal 5 with this on pressure transducer group 2, and pressing force is passed to pressure transducer group 2.Because this pilot thin plate 9 has the elasticity and the toughness of appropriateness concurrently, therefore shown in Fig. 4 (d), can fill the gap between wear 5b and the pressure transducer group 2, will be passed to the locational pressure transducer 4 relative from the pressing force of seal 5 effects with wear 5b.
At this moment, the pressing force that the locational pressure transducer relative with wear 5b 4 is suffered, be weaker than the suffered pressing force of the locational pressure transducer relative 4 with the 5a of appearance profile portion, but be positioned at the locational pressure transducer 4 relative and detect the engraving protuberance with wear 5b by suitably adjusting described threshold value, can make to be judged to be.In addition, Ci Shi threshold value preferably is set at a value less than described (X1+X2)/2.
In addition, carrying out manually under the situation of coining manipulation, might be with corner angle one end in contact of seal 5 in pushing the object face, perhaps the front end of seal 5 is hit and be connected to the object face of pushing with strength greater than needs, but, by with these pilot thin plate 9 shock absorbings, can prevent pressure transducer 4 damaged in the pressure transducer group 2.
And the print input device 1 of present embodiment also possesses the damping of shocks stance adjustment mechanism 12 that the supporter 11 to abutment pressure sensor groups 2 supports.
As shown in Figure 1, this damping of shocks stance adjustment mechanism 12 is arranged at supporter 11 following a plurality of volute springs 13 by the mode with supported body 11 and constitutes.And these volute springs 13 have both following function: supporter 11 is being applied under the situation of even pressing force, producing elastic deformation simultaneously and bring into play and make the function of supporter 11 in the damping of shocks mechanism of pressurized direction displacement; With under situation to the inhomogeneous pressing force of supporter 11 effects, as shown in Figure 5, when to pressure transducer group 2 with the front end of seal 5 obliquely under the situation of an end in contact, then performance makes them carry out elastic deformation with separately deflection respectively, allows that supporter 11 copies the front end face of seal 5 and make the function of the stance adjustment mechanism that posture changes.
Owing to can be subjected to before elastic deformation for described pilot thin plate 9 is unaffordable excessive external force in pressure transducer group 2, make volute spring 13 produce elastic deformation and then supporter 11 is moved in the pressurized direction, therefore can absorption prevent the damage of pressure transducer group 2 in the too much external force of pressure transducer group 2, and, front end at seal 5 is under the situation of an end in contact, can make the supporter 11 of abutment pressure sensor groups 2 copy the front end face of seal 5 and posture is changed, therefore, be effective structure especially at the print input device 1 of pushing the front end of seal 5 and then extracting trace to pressure transducer group 2 by manual operation.
In addition, carry out an end in contact at the front end of seal 5 and make under the situation that the posture of supporter 11 changes, as illustrative among Fig. 5, produce change for the pressing force of the front end of the seal 5 of pressure transducer group 2 separately according to the difference at position, and at this point, can be corresponding with it by the threshold value of suitably setting decision mechanism 6.
As damping of shocks stance adjustment mechanism 12, except volute spring 13, can also utilize oil damper etc.

Fig. 6 is the functional block diagram of structure of representing to be provided with simultaneously the print input device 15 of control part 14, wherein, described control part 14, with the front end of seal 5 by be pressed on the pressure transducer group 2 during, make more than 7 action of pressure transducer group 2, decision mechanism 6 and trace digitizing mechanism, and the information that has seal 5 leading sections temporarily is stored in the two-dimensional matrix on the storer 8a with the disjunctive form formula.The mechanicalness structure of relevant print input device 15, the structure of promptly relevant pilot thin plate 9, supporter 11, damping of shocks stance adjustment mechanism 12 etc., identical with embodiment shown in Figure 1, therefore omit its explanation.
In present embodiment 1, only carry out following operation repeatedly with the number of times that configures, that is: utilization possesses the translation circuit 3 of decision mechanism 6 and trace digitizing mechanism 7, with with described identical processing sequence, on storer 8a, temporarily store after the numerical data of trace as black and white 2 value images, with the data of the black in the pixel as benchmark, obtain the numerical data of storer 8b and storer 8a numerical data logic and, and with this logic and updated stored device 8a and storage, be white with the data reset all of storer 8b.Finally, the numerical data that will obtain in storer 8a is identified as the protuberance shape in the leading section of seal 5.
Under the situation of carrying out such processing operation, because in the starting stage, with the data reset all of storer 8a is white, therefore in the moment that at first pressure transducer group 2, decision mechanism 6, trace digitizing mechanism 7 is moved, at first, with the content among the storer 8b promptly in initial detecting operation the protuberance shape of the leading section of detected seal 5 directly transfer among the storer 8a resetting memory 8b again.
Then, when pressure transducer group 2, decision mechanism 6, trace digitizing mechanism 7 being started working in the second time, then will temporarily be stored among the storer 8b in the protuberance shape that current detecting operation is the leading section of detected seal 5 in the detecting operation second time, obtain the numerical data of storer 8b and storer 8a numerical data logic and, and with this logic and updated stored device 8a and store.Thereby, do not detect if exist in the initial detecting operation, but the shape of detected protuberance in second time detecting operation, then detected protuberance is in shape in initial detecting operation, add the shape of detected protuberance in second time detecting operation, and be stored among the storer 8a with the disjunctive form formula.
Then, by only carrying out set point number and above-mentioned same operation repeatedly, finally be identified as protuberance shape in the leading section of seal 5 with being stored in numerical data among the storer 8a.
Fig. 7 is used to illustrate the action principle figure that is set at the principle of work of control part 14 under 4 times the situation and storer 8a, 8b at the repetitive operation number of times with detecting operation.Like this, on the one hand when pressure transducer group 2, decision mechanism 6, the 7 every work of trace digitizing mechanism once, among the storer 8b just once being that unit obtains new numerical data, and on the other hand, among the storer 8a that has been reset in the initial period, when pressure transducer group 2, decision mechanism 6, the 7 every work of trace digitizing mechanism once, will keep under the prerequisite of existing black picture element obtaining new numerical data corresponding to black in the mode of appending, therefore, even some incorrect part in the pressing operation of seal 5 also can be in the protuberance shape in the leading section of final identifying stamp 5 exactly.
In this embodiment 1, be appended to storer 8a and storage by the new numerical data that will be equivalent to black, thus obtain logic and, but also can be in each detecting operation to storer 8b1 independently, 8b2,8b3 ... middle storage numerical data, and obtain storer 8b1 in terminal stage, 8b2,8b3 ... logic and, store into again among the storer 8a.

Below, with reference to Fig. 8～Figure 11, to being set simultaneously, clamping device and seal connect from travel mechanism, and the embodiment 2 that obtains the numerical data of trace in the robotization mode describes, wherein, described clamping device under the state of the front end face relative pressure sensor group 2 that makes seal 5, is pressed removably and is kept seal 5; Described seal connects from travel mechanism, with respect to pressure transducer group 2, clamping device is connect from moving.
As shown in Figure 8, print input device 16 possesses: the framework 17 of platform-like, be equipped with in it in the pressure transducer group 2 described in Fig. 1 and Fig. 2, pilot thin plate 9, supporter 11 and damping of shocks stance adjustment mechanism 12 etc.; Be configured in the clamping device 18 on the framework 17; And connect from travel mechanism 19 at the seal that above-below direction drives this clamping device 18.Also possess control part 20, its performance seal connects the function from drive controlling mechanism or the decision mechanism and the trace numerical data mechanism of travel mechanism 19.
Wherein, as shown in Figure 8, clamping device 18 is by constituting with the lower part: sliding part 24, and its main clamping part 23 and the swallow-tailed projection 21 that will delineate V groove 22 forms as one; Secondary clamping part 26, it possesses the V groove 25 relative with V groove 22, and mode is supported by axle to swing freely via pin 27 on sliding part 24.
Fig. 9 (a) is the cut-open view that shows to looking A-A cutting clamping device 18 with Fig. 8, and Fig. 9 (b) is the cut-open view that shows to looking B-B cutting clamping device 18 with Fig. 9 (a).
In addition, the swing of the secondary clamping part 26 on the counter clockwise direction in Fig. 9 (a) is allowed to rotate about about 90 ° from illustrated state.
On the V groove 25 of the V of main clamping part 23 groove 22 and secondary clamping part 26, be provided with the laminal slip-proofing device 29 that constitutes by synthetic rubber etc., fix 29, thereby the seal 5 that prevents to be clamped between the V groove 22,25 slides.
In addition, spiral shell is carved with the internal thread 31 that connects this projection 21 at above-below direction in dovetail shaped projection 21.
On the other hand, as shown in Figure 8, the seal that drives this clamping device 18 at above-below direction connects from travel mechanism 19 by constituting with the lower part: column 33, and the dovetail shaped projection 21 of delineating and being formed on the sliding part 24 is coincide, and the dovetail groove 30 that moves up and down of guiding clamping device 18; The feed screw 32 of the internal screw-thread screw that is provided with in the mode that connects dovetail shaped projection 21; And the stepping motor M1 that is used for this feed screw 32 is rotated driving.
Figure 10 is the block diagram that the structure that internally is loaded on the control part 20 of print input device 16 simplifies expression.
This control part 20 possesses: CPU34, and its performance connects function from the major part of the drive controlling mechanism of travel mechanism 19 and decision mechanism and trace digitizing mechanism as seal; ROM35, it stores control program of this CPU34 etc.; RAM36, its performance temporary transient storage operational data or the frame memory 8a of storage black and white 2 grey digital data, the function of 8b.Also possess interface 37, it is used for charging at bankbook the transmission of carrying out data between epigyny devices 38 such as device and the CPU34.Storer 8a, 8b distribute the part in the storage space of RAM36 to constitute, but its actual functional capability is but identical with storer 8a, 8b among the illustrated embodiment 1 of reference Fig. 6.
In addition, in the imput output circuit 39 of CPU34, be connected with: A/D change-over circuit 40 is used for signal to a plurality of sensors 4 of coming self-forming sensor groups 2 and carries out the A/D conversion and read in; With driver 41, it is used to drive described stepping motor M1, and be situated between and read in CPU34 from being arranged at start button SW1 on the framework 17 and the signal of cancel button SW2, and be configured in display 42 on the framework 17 and be situated between and carry out drive controlling by CPU34 by driver 43 by imput output circuit 39.
Below, with reference to the process flow diagram of Figure 11, the processing of CPU34 action is specifically described.Here, CPU34 performance meets drive controlling mechanism and decision mechanism and trace numerical data mechanism from travel mechanism 19 as seal, also has the function of automatic retry (retry) function and auto-reset function to realize the function of mechanism etc.
If in print input device 16, insert power supply, after then the tutorial message that CPU34 at first will " wish good health dress seal and press start button " etc. is presented on the display 42, according to the control program that is stored among the ROM35, begin to carry out processing, enter into the holding state (step S1) of wait by user's operation start button SW1 as Figure 11.
At this moment, the user resists the secondary clamping part 26 of being turned round the upward force of volute spring 28 and drawing back clamping device 18, and after clamping seal 5 between the V groove 25 of the V of main clamping part 23 groove 22 and secondary clamping part 26, unclamp hand, then seal 5 will be remained between main clamping part 23 and the secondary clamping part 26 by the upward swings power of being turned round volute spring 28.
Then, the user presses the start button SW1 on the lower frame body 17, then CPU34 is detected the operation of start button SW1 by the determination processing of step S1, thereby and begin to carry out just commentaries on classics that seal meets the stepping motor M1 in travel mechanism 19 and drive and make feed screw 32 rotations, and in the reduction action (step S2) that begins to carry out clamping device 18, and the timer T of the driving permitted hours of regulation stepping motor M1 is reset, last the time (step S3) after the beginning instrumentation clamping device 18 beginning down maneuvers.
Then, CPU34 is situated between and is detected the currency (step S4) of the drive current I of stepping motor M1 by driver 41, judge whether this drive current I reaches setting value i, the front end of promptly judging seal 5 whether with suitable power by the surface that is pressed in pressure transducer group 2 (step S5).
If drive current I does not reach setting value i, the front end that then means seal 5 in this step does not have with suitable power by on the surface that is pressed in pressure transducer group 2, therefore CPU34 judges further whether the timing of timer T reaches setting value t (step S6), if do not reach, then directly proceed the driving of stepping motor M1, and then continue to move down clamping device 18.
Like this, the result of determination of step S6 becomes under the genuine situation when carrying out the processing of step S4～step S6 repeatedly, even mean reduce front end that clamping device 18 can not make seal 5 with suitable power (set pressure) by on the surface that is pressed in pressure transducer group 2, mean that promptly the user fails correctly to install seal 5, therefore performance realizes the CPU34 of the function of mechanism as automatic return function, in display 42, show the demonstrations that makes mistakes such as " seal setup errors ", in a single day and at driving (the step S24 that stops stepping motor M1, step S25) after, change the reverse driving that begins to carry out stepping motor M1 into, upwards give (step S20) clamping device 18.
At this moment, bring into play automatic return function and realize that the CPU34 standby of the function of mechanism arrives (step S21) after pressure (imposition) scope of retreating positions to clamping device 18, confirming that clamping device 18 has been reset to the moment of retreating position, stop to drive stepping motor M1 (step S22), eliminate the demonstration that makes mistakes of " seal setup error " on the display 42, reset into initial holding state (step S23).
On the other hand, in the processing of carrying out step S4～step S6 repeatedly the result of determination of step S5 is become under the genuine situation, mean the surface of the front end of seal 5 with suitable power (set pressure) press pressure sensor groups 2, therefore performance meets CPU34 from the function of the control gear of travel mechanism 19 as seal, stop the driving of stepping motor M1, thereby guarantee pressed state (step S7) to the front end of the seal 5 of pressure transducer group 2, and in display 42, showing the information (step S8) that expressions such as " having begun to carry out trace extract " begins the extraction processing of trace, the value initialization with retryCounter (retry) C is 0 (step S9) simultaneously.
Then, CPU34 stores the beginning (step S10) that trace for the first time extracts operation the value of counter C is increased by 1 mode, and performance is situated between as the CPU34 of the function of decision mechanism and trace digitizing mechanism and reads in output X (step S11) from each sensor 4 that constitutes pressure transducer group 2 by A/D converter 40 and imput output circuit 39, and judge whether this value surpasses for example (X1+X2)/2 of pre-set threshold, if be that threshold value is when above on the one hand from the signal output X of pressure transducer 4, pixel memory location on the storer 8b of these pressure transducer 4 correspondences is set to represent the value " 1 " of black, if be threshold value when following from the signal of pressure transducer 4 output X on the other hand, the pixel memory location on the storer 8b of these pressure transducer 4 correspondences is set to represent the value " 0 " (step S12) of white.
Then, CPU34 is a benchmark with the data " 1 " of expression black, obtain the numerical data of storer 8b and storer 8a numerical data logic and, and with this logic and updated stored device 8a and storage (step S13), judge the occupied ratio of data " 1 " of expression black in storer 8a again, promptly judge the logic of the pixel of representing black and whether reach setting value (step S14).
Here, when the ratio that occupies the data " 1 " of representing black does not reach setting value, thereby in step S14, obtain under result's the situation of "No", mean that the engraving protuberance shape in the front end of seal 5 fails fully to be extracted at this constantly, therefore, CPU34 judges further whether the value of retryCounter C surpasses setting value C0, judges that promptly the trace that whether has carried out licensed number of times repeatedly extracts operation (step S15).
If the value of retryCounter C does not surpass setting value C0, then exist to continue to carry out the extraction operation of trace repeatedly and fully extract the possibility of engraving protuberance shape of the front end of seal 5, therefore, CPU34 further judges whether press cancel button SW2 (step S16) by the user.
At this moment, if do not press cancel button SW2, then bring into play the CPU34 processing of carrying out step S10～step S16 repeatedly same as described above that automatic retray function is realized the function of mechanism.
Like this, realize as automatic retray function by performance the CPU34 of the function of mechanism carry out repeatedly retry treatment step S10～step S16 during, the result of determination of step S14 becomes under the genuine situation, mean that then the protuberance shape of carving on the front end of seal 5 is stored device 8a and is extracted as registrable degree, therefore, CPU34 will be stored in numerical data among the storer 8a at current time, the data of common formation of promptly representing " 1 " and " 0 " of the engraving protuberance shape in seal 5 front ends, Jie is sent to (step S17) in the epigyny device 38 by interface 37, and from display 42 eliminations information such as " having begun to carry out trace extract ", and after the information such as " normal termination processing " that demonstration expression normal termination extraction is operated in display 42 (step S18), content among the storer 8a all is initialized as " 0 " (step S19), processing with described identical execution in step S20～step S23, after making clamping device 18 turn back to retreating position, the driving of stepping motor M1 is stopped, and from display 42, eliminate information such as " normal termination processing ", get back to initial holding state.
When the numerical data in will being stored in storer 8a is sent to epigyny device 38, its data layout is not particularly limited, but consider and epigyny device 38 between communication speed and the memory span etc. in each device, preferably use the little form of compressibility height and degradation.
In addition, because the numerical data that is stored among the storer 8a is in fact identical with the view data of carrying out 2 gray processings, therefore certainly carry out processing such as monitor demonstration or printout.
On the other hand, as mentioned above, carry out repeatedly during the retry processing of step S10～step S16, result of determination in step S15 becomes under the genuine situation, extract operation even then mean the trace that carries out only licensed number of times, also the engraving protuberance shape in the front end of seal 5 can't be extracted as registrable degree, therefore, bring into play automatic return function and realize that the CPU34 of the function of mechanism eliminates information such as " having begun to carry out trace extract " from display 42, and in display 42, show (step S26) after the error messages such as " trace extract failure " of extraction operation failure of expression trace, content among the storer 8a all is initialized as " 0 " (step S19), with the described identical processing of carrying out step S20～step S23, make clamping device 18 turn back to retreating position and remove from pressure transducer group 2, stop the driving of stepping motor M1, and from display 42, eliminate error messages such as " trace extract failure ", get back to initial holding state.
In addition, result of determination at step S16 becomes very, press under the situation of cancel button SW2 and detect by the user, mean that user's oneself requirement interrupts extracting operation, therefore, performance realizes that as automatic return function the CPU34 of body function eliminates information such as " having begun to carry out trace extract " from display 42, the indicator gauge system of expressing strong finishes trace and extracts (step S27) after the information demonstration that " processing is cancelled " of operation wait in display 42, content among the storer 8a all is initialized as " 0 " (step S19), the processing of carrying out step S20～step S23 same as described above, make clamping device 18 turn back to retreating position and remove from pressure transducer group 2, stop the driving of stepping motor M1, and from display 42, eliminate the information demonstration of " processing is cancelled ", get back to initial holding state.
As mentioned above, the print input device 16 of present embodiment 2 is the print input devices that possess following mechanism: clamping device 18 under the state of the front end that makes seal 5 with respect to pressure transducer group 2, keeps seal 5 by dismountable mode; Connect from travel mechanism 19 with seal, it connects from moving clamping device 18 with respect to described pressure transducer group 2.By the processing of step S1～step S7, seal meets the CPU34 that is used as the control gear of its essence from travel mechanism 19 and drives, till the leading section of seal 5 reaches the set pressure that the drive current i by stepping motor M1 represents.
And, as the pressure transducer group 2 of profile testing agency or decision mechanism and the trace digitizing mechanism that constitutes by CPU34, processing by step S9～step S16, value maximum according to setting value C0 only drives C0 time, and the protuberance that the front end shape of the seal 5 that will extract is during this period promptly carved is as the value " 1 " of representing black, and with the logic of accumulative total and updated stored in storer 8a, and the most at last this content as the digital data transmission of trace to upper device 38.
In addition, even when only with set point number driving pressure sensor groups 2, decision mechanism and trace digitizing mechanism, also fail to extract under the situation of the front end shape that can estimate as suitable trace, processing by step S15 and step S19～step 23, directly abandon the data of storer 8a and do not transfer to epigyny device 38, simultaneously, seal connect to reverse from travel mechanism 19 drive and clamping device 18 is reset to initial position of readiness, and make the each several part of print input device 16 get back to original state automatically.
In addition, even only drive permitted hours t in that seal is connect from travel mechanism 19, also the front end of seal 5 can't be docked under the situation of pressure transducer group 2, also identical therewith, processing by step S6 and step S19～step 23 does not transfer to epigyny device 38, reverses driving and seal connect from travel mechanism 19, clamping device 18 is reset to initial position of readiness, and make the each several part of print input device 16 get back to original state automatically.But owing to do not begin to carry out the extraction processing of trace this moment, the replacement that does not therefore need to carry out storer 8a is handled.
By with the extraction of step S10～step S16 operation as retry handle carry out repeatedly and in storer 8a resulting information, with the situation with reference to the embodiment 1 of Fig. 7 explanation is identical.
In this embodiment 2, because the front end of seal 5 is regularly with set pressure press pressure sensor groups 2, therefore can remember that big or small stabilization from the signal output of each pressure transducer 4 that constitutes pressure transducer group 2, its result, can compare when operating manually and judge the leading section that on each pressure transducer 4, whether has seal 5 better, and can improve reliability especially as the trace numerical data of final output.Thereby; in this case; the damping of shocks stance adjustment mechanism 12 of function that performance is used to cushion the damping of shocks mechanism of too much external force, protection pressure transducer group 2 just might not be set, and perhaps performance is copied the posture of seal and is adjusted the damping of shocks stance adjustment mechanism 12 of function of stance adjustment mechanism of the posture of pressure transducer group 2.In this embodiment 2, based on error message, with the setup error of seal 5 or read in being presented on the display 42 of mistake (the extraction mistake of trace) etc., because the each several part of print input device 16 automatically returns to original state when abnormal conditions take place, therefore be particularly suitable for the user carries out the seal registration by Self-Service situation.
More than, though exemplified embodiment and embodiment, concrete structure to print input device 1,15,16 is illustrated, but intermediate mediums such as paper about the front end shape that do not need to use transcription seal 5, and do not relate to the aspect that can accurately extract trace under the situation about staining etc. of front end face of seal 5, all have identical action effect.
As practical example of the present invention, can impress to substitute paper bill impression with electronic bill in the financial institution of bank etc., thereby can use the use of minimizing paper medium under the various situations of seal at needs.
