The correction of reference position and the decision of printing configuration

Next, with reference to Fig. 6 to Fig. 8, the correction of the paper end position as benchmark of the printing configuration of the data determining to print on printing surface is described.

Fig. 6 is the figure of the appearance representing booklet 100.X-direction shown in figure represents the direction that the binding unit of booklet 100 extends.Y-direction represents the direction orthogonal with the X-direction of the bearing of trend as binding unit, and in other words, Y-direction represents the direction of opening booklet 100.Z-direction represents the direction orthogonal with X-direction and Y-direction.Fig. 6 (a) for open paper 105 state under the stereogram of booklet 100, side view when Fig. 6 (b) is for observing from X-direction the booklet 100 opened, Fig. 6 (c) is side view when observing from Y-direction the booklet 100 opened.

Fig. 7 is the sectional view representing impression flat board and amount of movement measurement unit.Fig. 7 (a) represents between impression on the print position being configured at transmission path 30 dull and stereotyped 51 and printhead 22, is configured with state during single-part stationery 200 as print media.Fig. 7 (b) expression is configured with state during booklet 100 between impression dull and stereotyped 51 and printhead 22 as print media.Flow chart when Fig. 8 is the printing configuration of print control section 70 determination data.

As shown in Fig. 6 (a) and (b), if booklet 100 exposes the paper 105 be opened, then because paper 105 is by binding unit tractive, thus the paper end position of paper 105 is positioned at paper end position than the front cover of booklet 100 closer to the side of binding unit.Therefore, the paper end position of the paper end position of paper 105 and the front cover of booklet 100 is inconsistent, produces the deviation that departure is Δ Y in the Y direction.In addition, can produce air layer between the paper end position of the paper 105 on top stacked on Z1 direction and paper 105, therefore produce deviation in binding unit side further, so the stacked number of paper 105 is more, Y is larger for departure Δ.As mentioned above, the bracket 20 being equipped with the 1st optical sensor 21 moves and the paper end position detected is the paper end position of booklet 100, is equivalent to the paper end position of the front cover of booklet 100.Its result, as shown in Fig. 6 (b), the paper end position of the front cover of the booklet 100 detected by moving of bracket 20, relative to the paper end position of the paper 105 of the topmost as printing surface, can produce the deviation that departure is Δ Y.In addition, the distance P shown in Fig. 6 (b) is the distance (details is by aftermentioned) of the paper end apart from paper 105 such as the ruling printed in advance on paper 105 or tables.

On the other hand, in the X direction, in the booklet 100 being pasted with binding unit, even if open booklet 100, be also difficult to produce deviation between the paper end position and the paper end position of paper 105 of the front cover of booklet 100.But in booklet 100, binding unit is not by pasting but getting up by linear system sometimes, in this booklet 100, although seldom be there is a little paper 105 leeway away from each other by between the paper 105 of binding and paper 105.Therefore, as shown in Fig. 6 (c), press printing surface if bracket 20 is upper in the direction (X1 direction) of the arrow A of the bearing of trend (X-direction) of the binding unit along booklet 100 and slides, then the paper 105 of printing surface is dragged on X1 direction.Its result, the paper end position of the front cover of the booklet 100 that bracket 20 detects while the upper movement in the direction (X1 direction) of arrow A and become printing surface topmost paper 105 paper end position between produce the deviation that departure is Δ X.This departure Δ X is identical with departure Δ Y, and the stacked number of paper 105 is more, and deviation will be larger.In addition, the distance P shown in Fig. 6 (c) is the distance (details is by aftermentioned) of the paper end apart from paper 105 such as the ruling printed on paper 105 in advance or forms.

As mentioned above, for booklet 100, no matter when the bearing of trend of binding unit is along the moving direction of bracket 20, or when the bearing of trend of binding unit and the moving direction of bracket 20 intersect, when printing, the paper end of the paper 105 of printing surface all can produce deviation with the paper end position of the front cover of the booklet 100 detected.

The paper 105 of booklet 100 have printed ruling or form etc. in advance, easily to read the word or numeral that need print.At this, in printer 10, configure with the printing of the location matches ground determination data of this ruling or form etc.Therefore, the position of the paper end of booklet 100 is set to reference position by the print control section 70 of printer 10, according to the information be stored in advance in the storage area of print control section 70, distance P etc. such as from the paper end of printing surface to ruling or form etc., the printing configuration of determination data.But, as described above, between the paper end at the booklet 100 detected by the 1st optical sensor 21 and the paper end of the paper 105 as printing surface, produce departure Δ Y, Δ X.Therefore, the position that print control section 70 obtains adding error correction value on the paper end position detected is used as reference position, thus suppresses the data that need print to depart from the amount (S5, the S6 of Fig. 8) of ruling or form etc.

Error correction value is pre-stored in the storage area of print control section 70, when being judged as that print media is booklet 100, print control section 70, based on error correction value and the paper end position that detects, determines printing configuration (S5, the S6 of Fig. 8) of the data in printing surface.At this, (S1, the S3 of Fig. 8) that the kind of the print media control instruction that whether be booklet 100 be is received from main process equipment 1 by print control section 70 judges.Various signal (such as, various control instruction, print data, the printing medium information etc. such as execution of the execution of magnetic data read-write or the execution of paper transport or the execution printed or note detection) is sent from main process equipment 1 towards print control section 70.When the control instruction that print control section 70 receives comprises the such booklet 100 distinctive control instruction of execution of magnetic data read-write, print control section 70 judges that print media is booklet 100.Or print control section 70 also after the control instruction receiving magnetic data read-write, when magnetic data read-write success, can judge that print media is booklet 100.If do like this, even if then when main process equipment 1 do not identify print media be booklet 100 just to print control section 70 have sent magnetic data read-write control instruction, print control section 70 also can obtain the execution result of magnetic data read-write, thus judges whether print media is booklet 100.

In addition, according to the direction of insertion of booklet 100 towards printer 10, the bearing of trend of the binding unit of the situation that the moving direction of the bearing of trend and bracket 20 that can there is the binding unit of booklet 100 intersects and booklet 100 is along the situation of the moving direction of bracket 20.Between these two conditions, departure between the paper end of the paper end of the booklet 100 detected and the paper 105 of printing surface is different, usually, the bearing of trend that the residual quantity Δ Y when bearing of trend of the binding unit of booklet 100 and the moving direction of bracket 20 intersect is greater than binding unit is along the departure Δ X during moving direction of bracket 20.Therefore, error correction value also can adopt different values according to the direction of insertion of booklet 100.At this, the direction of insertion of booklet 100 can determine the specification into printer 10, also can notify print control section 70 from main process equipment 1.

In addition, as described above, the stacked number of paper 105 is more, and departure Δ Y, departure Δ X will be larger.Therefore, printer 10 possesses the encoder 54 of the amount of movement measurement unit of the thickness as metering booklet 100.As shown in Fig. 7 (a), (b), impression dull and stereotyped 51 passes through wind spring 52 to printhead 22 pressuring direction, if thus transfer printing medium between impression dull and stereotyped 51 and printhead 22, then impression dull and stereotyped 51 moves the amount corresponding to the thickness of print media towards the direction away from printhead 22.Therefore, between the impression on the print position being configured at transmission path 30 dull and stereotyped 51 and printhead 22, when being configured with the situation of single-part stationery 200 and being configured with the thick booklet of Thickness Ratio single-part stationery 100, the amount of movement of impression dull and stereotyped 51 is different.That is, if the booklet 100 that Thickness Ratio single-part stationery 200 is thick enters between impression dull and stereotyped 51 and printhead 22, then, compared with when entering with single-part stationery 200, the mobile quantitative change of impression dull and stereotyped 51 is large.As described above, in this impression flat board 51, possess the dull and stereotyped arm 51a of impression, form encoder 54 by the 2nd optical sensor 53 of the amount of movement of the dull and stereotyped arm 51a of impression and the dull and stereotyped arm 51a of detection impression.Print control section 70 drives encoder control part 76 (with reference to Fig. 5), and encoder 54 is worked, by detecting the amount of movement of this impression flat board 51, thus the thickness (S4 of Fig. 8) of metering print media.

Print control section 70, based on the error correction value corresponding to the thickness of the print media measured, corrects the reference position (S5 of Fig. 8) determined according to the paper end position detected.After this, based on this reference position, determine printing configuration (S6 of Fig. 8) of data in printing surface that need print.

Below, with reference to Fig. 6 (b), one of concrete example of the method for the printing configuration of determination data in printing surface is described.Such as, suppose, in booklet 100, have printed Form Frame in advance, print data from this position in the position of distance P of being separated by apart from the paper end of paper 105 of printing surface.In addition, now, the departure between the paper end of the booklet 100 detected and the paper end of the paper 105 of printing surface is set to Δ Y.So, the position wanting to start to print is the position of distance of (P+ Δ Y) of being separated by apart from the paper end of booklet 100.But, the paper end of what print control section 70 was grasped is booklet 100, therefore print be the paper end of the booklet 100 detected as reference position, from the position of distance P of being separated by apart from reference position.Therefore, the printing initiating position paper end become apart from booklet 100 has been separated by the position of P, and its result, deviate from the distance of Δ Y from wanting to the position of the printing of printing surface.

Thus, the position obtained after the paper end position of the booklet 100 detected adds value S to correct as the corresponding error correction value of the thickness of the direction of insertion and booklet 100 to booklet 100, is set to reference position from readout S in storage area by print control section 70.Known according to Fig. 6 (b), if add the correction of error correction value S on the paper end position of booklet 100, then the amount of answering with value S-phase is moved in reference position in Fig. 6 (b) towards right direction (that is, the direction of the paper end of the paper 105 of printing surface).Thus, printing initiating position become apart from reference position be separated by P position, namely become (P+S) from the paper end position of booklet 100.As shown in Fig. 6 (b), because the position wanting to start to print to be separated by the position of (P+ Δ Y) from the paper end position of booklet 100, the departure of position and the actual printing initiating position starting to print therefore is wanted to be improved as (Δ Y-S) from Δ Y.

At this, when error correction value S is equal with Δ Y, the departure of position and the actual printing initiating position starting to print is wanted to be " 0 ".In addition, error correction value S also can be fixing value.Thus, owing to not needing the thickness measuring booklet 100, therefore, it is possible to simplify the structure of printer 10.Especially, the maximum of Δ Y also can be measured in advance, by its 1/2 value error correction value S fixed.As above, no matter which paper 105 becomes printing surface, can make actual printing initiating position fifty-fifty and want the departure started between the position of printing to diminish.

Next, with reference to the flow chart of Fig. 8, the decision action of the correction of above-mentioned reference position and the printing configuration of data is described successively.First, if the print media such as booklet 100 or single-part stationery 200 is inserted into printer 10, then print control section 70 starts the action for determining to print configuration.

Step S1: the control instruction such as execution of the execution that print control section 70 detects from main process equipment 1 Reiceiver sheet or printing.
