The shapes from these reference coating divided areas _Yb1 to _{Yb11 are} divided by the shapes of the front side part 7e and the rear side part 7f, and further, the upper and lower sides of the first coating divided area _Ya1 to the eleventh coating divided area _Ya11 . As shown in FIG. 9 and FIG. 11, the edge portion is formed by adding a blurring process y that slightly degenerates the outline.
Upper and lower ends, since allowance overlap at the boundary portion to the adjacent reference painting divided area Y _b to each other are formed, the overlap margin is order to achieve uniformity of density can not be clearly recognized. The first paint division area Y _a1 to the eleventh paint division area Y _a11 that have received this blurring process y are referred to as the first reference paint division area Y _b1 to the eleventh reference paint division area Y _b11 .

Thus, by setting the shape along the surface shape of the side plate portion 7A, as compared with the case where the reference paint divided area Y _b are arranged in a rectangular or square to the surface creating, protrudes from the reference paint divided area Y _b In this way, color development is improved and accurate printing without distortion can be performed.

Next, the area setting in the front plate part 7B will be described. In the grip base portion 7D from the attachment base end portion 7C, as shown in FIGS. 12 (a) to 12 (g), a plurality of twelfth coating divided regions _Ya12 to fifteenth coating divided regions _Ya15 are set. In particular,
(1) As shown to Fig.12 (a), 12th coating division area _Ya12 is set with the shape of one side part 7g of the attachment base end part 7C and the grip part 7D.
(2) As shown in FIG. 12 (b), in a state where it is shifted by ¼ d _th from the twelfth coating divided region _Ya12 to the other side portion 7h that is a pair of one side portion 7g, A thirteenth reference _prepainted divided area _Ya13 is set according to the shape of the side part 7g.
(3) As shown in FIG. 12 (c), 13 reference before painting divided area _{Y a13} one to paired other side portion 7h side of the side portion 7g quarter _{1d th} shifted state from Thus, the fourteenth paint division area _Ya14 is set according to the shape of the other side portion 7h.

As shown in the figure, the front plate portion 7B has a gentle arc surface shape, and since the grip portion 7D is narrower than the mounting base end portion 7C, the brake lever 7 itself has a truncated cone surface. ing. Therefore, it is necessary to apply a large deformation than the shape of the reference paint divided area Y _b in the plane plate-shaped side plate portion 7A. In particular,
(1) As shown in FIG. 13 and FIG. 14, it is partitioned by the shape of one side portion 7g of the attachment base end portion 7C and the grip portion 7D, and subjected to a deformation process suitable for the surface shape of the surface to be painted. A twelfth reference paint division area _Yb12 is set.
For example, when creating a surface by placing regular squares on a truncated cone surface without gaps, an overlap margin is generated at an adjacent portion. In order to avoid this, the twelfth reference coating divided region _{Yb12, which} is the basic shape for creating the surface, must have a substantially trapezoidal shape. Therefore, since the other side portion 7h to be paired in one side portion 7g is not come appear in the 12 divided regions X ₁₂ in, a modification of the twelfth painting divided region Y _a12 substantially trapezoidal shape, 12 reference The coating division area _Yb12 was set.
(2) shown in FIGS. 13 and 14, 13 divided regions _{X 13,} so is split in a state in which the first 12 divided region _{X 12} from displaced to the other side portion 7h side only 4 minutes _{1d th,} both of the side end edge 7 g, 7h does not come appear to the 13 divided regions _{X 13.}
Therefore, the thirteenth reference paint division area _Ya13 was deformed into a substantially trapezoidal shape, and the thirteenth reference paint division area _Yb13 was set.
(3) As shown in FIGS. 13 and 14, since the 13 divided regions _{X 13} than on the other side portion 7h side only shift state quarters of _{1d th} 14th divided region _{X 14} are formed, the other side portion 7h come evident to the 14 divided regions _{X 14.} Therefore, the other side portion 7h was introduced, the fourteenth paint division area _Ya14 was transformed into a substantially trapezoidal shape, and the fourteenth reference paint division area _Yb14 was set.
(4) As shown in FIGS. 13 and 14, 15 reference paint divided area _{Y b15} is only a state deviated by a quarter of _{1d th} on the other side portion 7h side, geometric substantially the The trapezoidal shape is the same as the 14th reference coating divided region _Yb14 .
(5) As shown in FIG. 13 and FIG. 14, blur processing that slightly delineates the upper and lower ends of the twelfth reference paint division area Y _b12 to the fifteenth reference paint division area Y _b15 created as described above. y is added.

Next, it is necessary to add a printable process to the reference paint division area Y. That is a process called a bitmap process, and the bitmap process is a process of interpreting an image expressed in a data format and converting it into a pit map format that can be printed by an ink jet type coating apparatus F.
For example, the image is analyzed into an image of four primary colors: c (cyan), m (magenta), y (yellow), and k (black), and the color density is also added to the image. These data are sent to the control means for ink ejection.

Next, the control flow will be described. As shown in Fig. 2 (a), the image processing control flow is as follows.
(1) Capture an illustrator image (STP1).
(2) Image segmentation, deformation processing, and both-end blur processing are performed simultaneously (STP2).
(3) RIP processing is performed (STP3).

The ink ejection process control is as follows. In response to the image RIP process,
(1) Which nozzle is ejected from?
(2) How much is ejected?
(3) How fast is the ejection speed?
(4) From which nozzle the ink is ejected when the workpiece comes to which position (STP4).
The above control is performed simultaneously.

  The control mode as described above will be described with reference to the control configuration diagram and the control flow diagram of FIG. 2 and 3, the ink jet head 2 is abbreviated as an ink head. As shown in FIG. 3, from workpiece movement amount detection sensors 23 a and 23 b that measure the movement distance of the workpiece 7 as a brake lever, a workpiece support axis rotation detection sensor 22 that measures the rotation amount of the workpiece 7, and a start switch 24. The control device 21 adjusts the ink ejection amount from the ink supply / ejection device 13 while driving the workpiece slide movement drive device 25 and the workpiece support shaft rotation drive device 12 to obtain the inkjet information. Ink droplets are supplied from the head 2 to advance the painting process. The control device 21 is an electronic device including a CPU, a memory, and an interface.

The form of spray coating on the inkjet head 2 is as follows. That is, as shown in FIGS. 9 and 10, those from the first division region _{X 1} by arranging the 10 divided regions _{X 11} and the 12 divided regions _{X 12} from the 15 divided regions _{X 15,} again, first reference It divides _{| segments} from the coating division area _Yb1 to the required Nth reference _| standard coating division area _bn , and it coats on the basis of the reference _| standard coating division area Y.
The form for performing the painting is a multi-pass system. The multi-pass method means that the inkjet head 2 does not perform coating in a single stroke, but performs the coating by moving the same portion a plurality of times.

Specifically, it is as shown in FIGS.
(1) As shown in FIG. 10 (a), performing the coating with respect to the first reference paint divided area _{Y b1} of the first divided region _{X 1} shown in FIGS. In this case, the inkjet head 2 is moved along the long width direction of the first reference coating divided region _Yb1 , and the coating width of the ink jet head 2 along the short width direction _dth orthogonal to the long width direction l is determined.
(2) Next, as shown in FIG. 10B, coating is performed on the second reference coating divided region Y _b2 that is shifted from the first reference coating divided region Y _b1 by ¼ d _th in the short width direction. Accordingly, only 3 / 4th _th is to be painted twice.
(3) Next, as shown in FIG. 10 (c), a painting from a quarter of _{1d th} position shifted by a further short width direction from the second reference paint divided area _{Y b2} the third reference paint divided area _{Y b3} Do. Thus, only a quarter of 2d _th top of the drawing in the third reference paint divided area Y _b3 becomes to be subjected to coating in triplicate, only 1d _th thereunder quarter, facilities painted double In addition, the lower quarter _dth is painted in a single layer.
(4) Next, as shown in FIG. 10 (d), the coating from the third reference paint divided area _{Y b3} position deviated by further _{1d th} quarter in the short width direction from the fourth reference paint divided area _{Y b4} Do. Accordingly, in a quarter of 1d _th separated in the short width direction from the top of the figure in the fourth reference paint divided area Y _b4, quadruple, triple, double, would be subjected to painting singlet.
(5) As described above, the multi-pass coating can be performed by coating the reference coating divided region Y from the position shifted by ¼ d _th , as shown in FIG. In this case, there are parts that are painted in quadruple, triple, double, and single.
Moreover, the coating form with respect to the front-plate part 7B of the brake lever 2 is demonstrated based on FIGS.
(6) As shown in FIG. 14 (a), performing the coating to a 12 reference paint divided area _{Y b12} of the 12 divided regions _{X 12.} In this case, the inkjet head 2 is moved along the long width direction of the twelfth reference coating divided region _Yb12 .
(7) Then, as shown in FIG. 14 (b), performing the coating from the 12 reference paint divided area position deviated only _{1d th} quarter in the short width direction from _{Y b12} to the 13 reference paint divided area _{Y b13} . Accordingly, only 3 / 4th _th is to be painted twice.
(8) Next, as shown in FIG. 14 (c), the paint from the 13 reference paint divided area _{Y b13} position deviated by further _{1d th} quarter in the short width direction from the second 14 reference paint divided area _{Y b14} Do. Thus, only a quarter of 2d _th over on 14th reference paint divided area Y _b14 definitive drawings, will be subjected to coating in triplicate, only 1d _th thereunder quarter, facilities painted double In addition, the lower quarter _dth is painted in a single layer.
(9) Next, as shown in FIG. 14 (d), the paint from the 14 reference paint divided area _{Y b14} position deviated by further _{1d th} quarter in the short width direction from the second 15 reference paint divided area _{Y b15} Do. Accordingly, in a quarter of 1d _th separated in the short width direction from the top of the drawing in the 15 reference paint divided area Y _b15, quadruple, triple, double, it would be subjected to painting singlet.
As described above, by performing the coating to a reference coating divided area Y _b from 4 minutes of 1d _th shifted position, it can be performed paint multi-pass method, the case shown in FIG. 14 (d) There will be quadruple, triple, double, and single painted areas. Note that, finally, the single, double, and triple paint portions may be quadrupled.

For example, while the brake lever 7 as a work along a first divided region X ₁ slides driven by an electric cylinder 25A, so that the ink is applied to the first reference paint divided area Y _b1, the control unit 21, the ink The supply / injection device 13 is controlled.
For example, the ink jet head has a 300 dpi specification, and each ink head has a large number of nozzle holes. To the width of the reference paint divided area Y _b, select the nozzle holes to be used, and is performed based on the ink ejection process control.
In the control of ink droplets, error diffusion is used, and in expressing the color intensity, the same density is used depending on whether large droplets are arranged with coarse density or small droplets are arranged densely. Can be expressed and automatically controlled according to the situation.

  Specifically, when a composite color other than the four primary colors: c (cyan), m (magenta), y (yellow), and k (black) is to be produced, one of the nozzle holes that eject the four primary colors is the target. When one of the four primary colors is ejected when the nozzle reaches the ejection position, and when one nozzle of the next four primary colors reaches the ejection position following a very short time, the other of the four primary colors is ejected. One of the four primary colors is ejected, and when the remaining one nozzle of the next four primary colors reaches the ejection position in a very short time, the remaining one of the four primary colors is ejected. As a result, a composite color at the ejection position is formed.

The control mode described above will be described with reference to FIG.
(1) When the start switch 24 is ON, the image processing data is fetched. Ink ejection process data is taken in and it is determined whether or not the workpiece is at a predetermined position (STP10 to 12).
When the work is at a predetermined position, the work is moved along the first paint division area Y _a1 and ink is ejected along the first reference paint division area Y _b1 (STP13 to 14).
(2) It is determined whether or not one stroke has been completed. When the first stroke is completed, the work is returned to a predetermined position (STP15 to 16).
(3) With the workpiece returned to a predetermined position, it is detected whether or not there is _a next paint division area Ya, and if there is, the workpiece is moved in the Y-axis direction by the workpiece slide movement drive device 25B. moving the second coating divided region _{Y a2} of the lower ink jet head 2 (STP17~18).
When the work is the brake lever 7 and the side plate 7A has been painted, it is necessary to shift to the front plate 7B, so the work is rotated around the support shaft (STP19 to 20). Then, the same operation as described above is performed.
(4) In order to perform the entire surface of the brake lever 7, after the front plate portion 7B is finished, the work is rotated again to perform the opposite side plate portion 7A, and the process ends. In this case, since the next reference painting division area Y is eliminated, the operation is finished (STP21 to 22).
As described above, in the next step, the method of applying ink so as to partially overlap the previously applied coating is read as multi-pass. As described above in connection with the technique, the number of passes can be arbitrarily selected.

[Second Embodiment]
The rear derailleur W, which is a bicycle component as a leisure device, will be described.
As shown in FIG. 15, the rear derailleur W includes a bracket body 15 having a box-shaped connection case 15 </ b> A connected to the vehicle body via a support plate (not shown), and a speed change operation wire attached to the bracket body 15. The tool 16, the right link 17 and the plate holder 18 (the left link is not shown) constituting the parallel quadruple link attached to the bracket body 15, the plate holder 18, and the body 16 are attached to the vehicle body. The plate body 19 is provided with a guide pulley 20A and a tension pulley 20B that guide chain replacement on a plurality of freewheels.

  When the speed change lever 6 is operated, the four-link mechanism is operated via the speed change wire, and the support frame 19 together with the plate holder 18 is displaced in the axial direction of the guide pulley 20A, so that the chains are different. Shifting operation that can be changed to a wheel becomes possible.

  The painting of the right link 17 used in the rear derailleur W will be described. As shown in FIG. 16, here, as will be described later, since the curved portion 17A of the right link 17 is coated, the right link 17 serving as a work is rotated each time one process is completed. The structure of the adjusting table 5 shown in the first embodiment is not required. Rather, it is required to set the posture of the workpiece freely by supporting the supporting workpiece on an articulated type such as a robot arm.

Next, a method for painting the right link 17 will be described. First, image division processing is performed to set a reference paint division area. As shown in FIG. 16, the painting target surface of the second link 17 is not a flat surface but a curved surface portion 17A, and the curved surface portion 17A exhibits a bulging state gradually toward the center portion. I will explain the painting method focused on. Subdivide coated target surface to the eye-shaped divided areas X of the elongated web along a longitudinal direction, and the coating divided region Y _a, which is restricted to the outer shape included in the divided region X corresponding to the three-dimensional surface shape of the coated object surface subjected to deformation processing to form the reference paint divided area Y _b, in fact, set the shape of the reference paint divided area Y along the curved shape.

As shown in FIG. 18, the curved portion 17A, 6 pieces of the reference paint divided area from the 21 reference paint divided area _{Y b21} to 26 reference paint divided area _{Y b26} is set. The shape of these reference paint divided area Y _b21 to Y _b26, as the curved portion 17A is described above, the paper on the left and right center position wider, but at the left and right ends having a substantially drum-shaped short width, and left and right As shown in FIGS. 18 and 19 (a) to 19 (f), _a substantially trapezoidal deformation process is applied from the coating divisional area Ya described later, as it is rounded so that it rises upward and downward in the center side. , so that the reference paint divided area Y _b is clarified, data processing is performed.
Thus, by adding the deformation process, as compared with the case of the surface created by arranging the reference paint divided area Y _b square, without protruding from the base paint divided area Y _b, coloring and the like are improved.

  Next, image segmentation specified in the control flow described later will be described. When performing printing, if a sufficiently large nozzle or inkjet head 2 is used, there is no need to use such a method of image separation, but the amount of ink that can be applied in one stroke and the application width are as follows: Since the size of the nozzle and the inkjet head 2 is limited, in order to perform the coating within the limitation, the following image separation is performed to efficiently apply the ink.

The surface to be coated of the curved surface portion 17A to be painted is subdivided into elongated mesh-like divided regions X along the longitudinal direction. As shown in FIG. 16 and FIGS. 17A to 17F, the width of ink application is d _th .
(1) First, a portion including the upper side portion 17e on the paper surface is cut out. This portion is referred to as a first 21 divided region _{X 21,} width length at _{d th} exhibits a length _{l 1} of a square-shaped right link 17. The first 21 divided region _{X 21} is 16, and is shown in FIG. 17 (a). The first 21 divided region _{X 21,} as shown in FIG. 17, the 21 paint divided region _{Y a21} including upper portion 17e of the curved portion 17A is formed. This 21st painting division area _Ya21 is only restricted by the outer shape of the painting surface, shows the thing before receiving the deformation process described later, and does not receive the blurring process.
(2) Next, as a part and the 21 divided regions _{X 21} (tens% of the width _{d th)} overlap, and carving a state was a little shifted to the lower portion 17f side on the paper surface. This portion is referred to as a _twenty- second divided region _X22 , and has a rectangular shape or a rectangle having a width d _th and a length l ₁ of the curved surface portion 17A. The 22nd division region _{X 22} is 16, and is shown in FIG. 17 (b). In the first 22 divided region _{X 22,} 22 paint divided region _{Y a22} including upper portion 17e of the curved portion 17A is formed. This 22nd paint division area _Ya22 is only restricted by the outer shape of the paint surface, shows a part before undergoing the deformation process described later, and has not been subjected to the blur process.
However, with regard to the point of “cutting with a slight shift to the lower side 17f side on the paper surface”, the curved surface portion 17A to be painted is actually rounded so that it rises toward the left, right, up, down, and center side. Thus, the twenty-second coating division area _Ya22 is positioned below the inkjet nozzle 2 in a state in which the twenty-first coating division area _Ya21 is slightly rotated toward the upper side 17e while being positioned below the inkjet nozzle 2. Indicates the state. The calculation of the slightly rotated angle is performed as follows.
That is, considering an arc corresponding to the width d _th on the curved surface portion 17A, a quarter of an angle formed by connecting both ends on the circumference of the circular arc and the center of curvature of the curved surface portion 17A is a desired angle. That is, the length of the width d _th is considered as a chord in the arc of the curved surface portion 17A, and the distance between one end on the circumference of the arc and the center of curvature is the radius of the arc, so the angle is a minute angle. Taking into account, the obtained angle α is
α = 1/4 × arcTANG (width d _th length / arc radius)
It is.
(3) Next, 21 divided regions _{X 21} and, so as to partially overlap the first 22 divided region _{X 22,} and carving a state was a little shifted to the lower portion 17f side. This portion is referred to as a first 23 divided region X _23, width length at d _th exhibits rectangular length l ₁ of the brake lever. The 23rd divided region _{X 23} in FIG. 16 and is shown in FIG. 17 (c).
In the first 23 divided region _{X 23,} since the upper portion 17e of the curved portion 17A is also not present lower portion 17f, 22 paint divided region _{Y a22} square is formed. This 22nd paint division area _Ya22 is only restricted by the outer shape of the paint surface, shows a part before undergoing the deformation process described later, and has not been subjected to the blur process.
(4) As described above, one after another, as paint divided region Y _a overlap each other partially, or so that a double triple, will cut state was a little shifted to the lower portion 7f side. In this case, since it is divided so as to overlap each other by a quarter of the width d _th , a double and triple overlap allowance is formed. This overlap allowance is compared with work efficiency and good finish. Any number can be selected.
(5) in FIG. 17 (a) ~ (f), shows six paint divided region _{Y a.}

Next, by performing transformation process from painting divided region Y _a, as shown in FIGS. 18 and 19 show a state in which a reference paint divided area Y _b.
(1) As shown in FIG. 18, based on the 21st painting division area _Ya21 , the deformation | transformation process along the surface shape of the coating target surface was performed, maintaining the shape of the upper side part 17e of the curved-surface part 17A. A twenty-first reference paint division area _Yb21 is set. Here, the deformation process is performed for the following reason. The curved surface portion 17A described above is derived from the point that the central position on the paper surface of FIG. 12 has a large diameter and exhibits a part of a substantially truncated cone surface that decreases in diameter toward the left and right ends.
For example, when creating a surface by placing regular squares on a truncated cone surface without gaps, an overlap margin is generated at an adjacent portion. In order to avoid this, the twenty-first reference coating divided region _{Yb21, which} is the basic shape for creating a surface, must have a substantially trapezoidal shape. Therefore, the lower side portion 17f forming a pair of upper side portion 17e was set does not come appear in the 21 paint divided region X _21, the square shape of the 21 reference paint divided area Y _b21 substantially trapezoidal shape.
(2) shown in FIG. 18, the 22 divided regions _{X 22,} so is split in a state in which the first 21 divided regions _{X 21} from displaced to the lower side 17f side only 4 minutes _{1d th,} the central portion of the upper side portion 17e not come appear to the 22 divided regions _{X 22.} But others were set to a 21-division is similar as region _{X 21,} substantially trapezoidal shape 22 reference paint divided area _{Y b22} As with the 21 reference paint divided area _{Y b21.}
(3) shown in FIG. 18, the 23 divided regions _{X 23,} so is split further state shifted to the lower portion 17f side only 4 minutes _{1d th} than the 22 divided regions _{X 22,} the central portion of the upper side portion 17e Although but not come also reflected to the 23 divided regions _{X 23,} others are the same as the 22 divided regions _{X 22,} substantially trapezoidal the first 23 reference paint divided area _{Y b23} as with the 22 reference paint divided area _{Y b22} Set to shape.
(4) As shown in FIG. 18, 26 divided regions _{X 26} from the 24 divided regions _{X 24} is because it is formed vertically subject from the 21 divided regions _{X 21} and the 23 divided regions _{X 23,} 24 coating divided region _{Y a24} from the 26 paint divided region _{Y a26,} and, from the 24 reference paint divided area _{Y b24} 26 reference paint divided area _{Y b26,} are respectively 23 painting divided regions from the 21 paint divided region _{Y a21} Y _a23 and the twenty-first reference coating divided region Y _b21 to the twenty-third reference coating divided region Y _b23 are set in a vertically symmetrical shape.
(5) The upper and lower end portions of the thus 26th reference painting divided from the 21 reference paint divided area Y _b21 created region Y _b26, as shown in FIGS. 18 and 19, blurring y to blur slightly contour Is added.
The upper and lower end portions are for the purpose of making the density uniform so that the overlap allowance cannot be clearly recognized because the overlap allowance is formed at the boundary portion between the adjacent reference coating divided regions Y.

Then, 18, a plurality of the 21-minute region X ₂₁ having a reference paint divided area Y plus blurring side by side 26 divided regions X ₂₆ vertically, and ends the image processing. However, in the above case, six divided regions are arranged, but the number arranged can be selected according to the necessary number of divisions.
The form which actually paints with the above structure is demonstrated.
Further, a painting mode for the right link 17 of the rear derailleur W will be described with reference to FIG.

(3) Next, as shown in FIG. 19 (c), performing the coating from the 22 divided regions _{X 22} et Furthermore _{1d th} position shifted by a quarter in the short width direction to the 23 reference paint divided area _{Y b23.} Thus, only a quarter of 2d _th top of the drawing in the 23 reference paint divided area Y _b23 becomes to be subjected to coating in triplicate, only 1d _th thereunder quarter, facilities painted double In addition, the lower quarter _dth is painted in a single layer.
(4) Next, as shown in FIG. 19 (d), performing the coating further from the position deviated by a quarter of _{1d th} in the short width direction from the 23 divided regions _{X 23} to the 24 reference paint divided area _{Y b24.} Accordingly, in a quarter of 1d _th separated in the short width direction from the top of the drawing in the 24 reference paint divided area Y _b24, quadruple, triple, double, it would be subjected to painting singlet.
(5) Next, as shown in FIG. 19 (e), performing coating further four minutes of _{1d th} position shifted by the short-width direction from the 24 divided regions _{X 22} to the 25 reference paint divided area _{Y b25.} Accordingly, in a quarter of 1d _th separated in the short width direction from the top of the drawing in the 25 reference paint divided area Y _b25, quadruple, triple, double, it would be subjected to painting singlet.
(6) Next, as shown in FIG. 19 (f), performing the coating from the 25 further from the divided region _{X 25} deviated by _{1d th} quarter in the short widthwise position to the 26 reference paint divided area _{Y b26.} Accordingly, the coating is applied in quadruple, triple, double, and single at a quarter _dth division in the short width direction from the top of the drawing in the twenty-sixth reference coating divided region _Yb26 . Note that, finally, the single, double, and triple paint portions may be quadrupled.

Next, it requires printable process based paint divided area Y _b. That is a process called a pit map process. The pit map process interprets an image expressed in a data format and converts it into a pit map format that can be printed by the ink jet type coating apparatus F.
For example, the image is analyzed into an image of four primary colors: c (cyan), m (magenta), y (yellow), and k (black), and the color density is also added to the image. These data are sent to the control means for ink ejection.
