As shown in Figure 1, from be formed at needle stand member 19 lower face side pin bearing-surface 19a with the mode relative with object workpiece (applied thing) W towards below the outstanding many coating needle 3 that are provided with.The cardinal extremity 3b of each coating needle 3 is fixed on pin bearing-surface 19a.Be positioned at from pin bearing-surface 19a and give prominence to each coating needle 3 is set away from the mode the same plane of the position of given size with the front end 3a of many coating needle 3.Therefore the front end 3a that, is arranged in the many coating needle 3 on pin bearing-surface 19a is taking the surface of the workpiece W height identical as benchmark is arranged in.
Needle stand member 19 is held in mobile base member 17 by 18 of elastic supporting parts that are made up of elastic component, and this mobile base member 17 is fixed in sliding component 16.In addition, when this sliding component 16 is because the driving of base travel mechanism 5 is in the time that upper and lower upward sliding moves, the distance that the front end 3a that is arranged in the multiple coating needle 3 on pin bearing-surface 19a can remain to till workpiece W is on one side equidistant, on one side close, away from workpiece W.In the time utilizing base travel mechanism 5 that multiple coating needle 3 are declined towards workpiece W, the correction ink 11 that is attached to the front end of multiple coating needle 3 is coated with, and is essentially rectangular shape to be coated with out the shape identical with the applied portion shape of the workpiece W as object.
Fig. 3 is the figure that represents the action of coater unit 2 in the situation that applied region WV tilts.While being located at a part of front end 3a in the front end 3a of many coating needle 3 of needle stand member 19 lower face side surperficial butt with applied region WV more first than other front end 3a, be passed to elastic supporting part 18 via needle stand member 19 from the pressing force of the coating needle 3 of elder generation and front end 3a butt.The periphery of the elastic supporting part 18 directly over the coating needle 3 of the pressing force that transmission comes to first butt is pressed so that its strain.Thus, needle stand member 19 tilts along applied region WV with respect to mobile base member 17, and parallel with the surface of applied region WV.Therefore, the front end 3a of all coating needle 3 including the front end 3a of coating needle 3 and the front end 3a of other coating needle 3 of first butt and the surface butt equably of applied region WV.
Therefore,, even if the surface tilt of applied region WV, the front end 3a of all coating needle 3 is also impartial and because the elasticity of elastic supporting part 18 is to have the mode Elastic Contact of resiliency of expectation.
In addition, as elastic supporting part 18, as long as rubber system, leaf spring system etc. with the front end 3a of multiple coating needle 3 can with the surface in the applied region member of the mode generation strain of butt equably, form elastic supporting part 18 member shape, quantity and material not Bei Te Do limit.
Fig. 4 (a1)～Fig. 4 (d2) is the figure that represents the coating action of apparatus for coating 1.As shown in Fig. 4 (a1), Fig. 4 (a2), on the pin bearing-surface 19a of needle stand member 19, arrange many coating needle 3 are installed.First, the front end 3a of many coating needle 3 is fixed on the position relative with the liquid level of the correction ink 11 of print cartridge 12.
Then, drive base travel mechanism 5 that needle stand member 19 and many coating needle 3 are declined, as shown in Fig. 4 (a1), the front end 3a of many coating needle 3 is immersed in the correction ink 11 in print cartridge 12.Now, the front end 3a of each coating needle 3 is immersed in and revises in ink 11 with the degree of depth of regulation.
Then, drive base travel mechanism 5 to make needle stand member 19 and many coating needle 3 increase, the front end 3a of each coating needle 3 is moved to the top of print cartridge 12.As shown in Fig. 4 (b1), around the front end 3a of the each coating needle 3 from print cartridge 12 interior liftings, be attached with the correction ink 11 of desired amount.Correction ink 11 maintenances of the front end 3a of each coating needle 3 and the independently state of correction ink 11 of the front end 3a of other coating needle 3.
As shown in Fig. 4 (b2), be attached with roughly spherical correction ink 11 at the front end 3a from each coating needle 3 of print cartridge 12 interior liftings.
Then, as shown in Fig. 4 (c1), use the XY worktable 40 of being controlled by master computer 30, make the applied region of workpiece W relatively move to the below of the pin bearing-surface 19a of needle stand member 19.Then,, in the time that the coating needle 3 that drives base travel mechanism 5 to make to be fixed on needle stand member 19 declines, the front end 3a of each coating needle 3 and the surperficial butt of workpiece W, to coat applied region by correction ink 11.
Now, as shown in Figure 3, the elastic supporting part 18 between insertion needle stand member 19 and mobile base member 17 absorbs the power of the front end that puts on coating needle 3 by strain.Thus, can reduce the possibility that makes the front end distortion of coating needle 3 etc. because of load partially.
,, in the coater unit 2 of embodiment one, as shown in Figure 3, even if in the situation that workpiece W tilts, also can tilt because of the inclination that the strain of elastic supporting part 18 makes needle stand member 19 follow workpiece W.Therefore, the front end 3a of coating needle 3 respectively with the surperficial approximate equality ground butt in the applied region of workpiece W.In addition, in Fig. 3, show the workpiece W under normal level with double dot dash line, show the workpiece W being inclined relative to horizontal with solid line.
Thus, it is impartial that the pressing force of the front end 3a of many coating needle 3 becomes, thereby can not apply uneven load to the front end 3a of a part of coating needle 3.Therefore, can be coated with in heterogeneity correction ink 11 in the surperficial applied region from the front end 3a of many coating needle 3 towards workpiece W.
After just coating, in the time driving base travel mechanism 5 to make coating needle 3 increase, as shown in Fig. 4 (c2), revise the surface that ink 11 is point-like and residues in workpiece W.
As shown in Fig. 4 (d1), Fig. 4 (d2), when from coating during through the stipulated time, the surperficial correction ink 11 of coating workpiece W flows, adjacent correction ink 11 each other fit, mix and be integrated, and become the membranaceous ink layer with uniform thickness.Finally, make this ink layer dry, curing, and finish the correction of defect part.
[comparative example one]

(embodiment 11)
In the coater unit 2 of embodiment one, the front end 3a of many coating needle 3 along plane and the uneven situation of applied region WV under, utilize the strain of elastic supporting part 18 to carry out absorption dip, so that the surface butt equably of the front end 3a of many coating needle 3 and applied region WV.
But, strictly speaking, for absorption dip, need make the front end 3a of coating needle 3 move in the mode of sliding with respect to applied region WV, or the cardinal extremity 3b of coating needle 3 is moved in the horizontal direction.
For example, as shown in figure 25, suppose the only absorption dip of distortion of elastic supporting part 18, and there is fulcrum P in the central upper portion of elastic supporting part 18 in hypothesis.In addition, in Figure 25, in order to simplify accompanying drawing and explanation, omit the diagram of needle stand member 19, and represented multiple coating needle 3 with a quadrangle.In this case, when making elastic supporting part 18 and coating needle 3 in the time that the workpiece W tilting vertically declines, make the inclination variation of elastic supporting part 18 and coating needle 3 according to the inclination of workpiece W.Now, as shown in figure 25, the contact position of the front end 3a of coating needle 3 and the Surface Contact of workpiece W moves a certain apart from d1 from being coated with to when coating.In addition, if the front end 3a of coating needle 3 does not move, cannot absorb the inclination of workpiece W.
But in the time that the contact position of the front end 3a of coating needle 3 moves, the precision of coating position reduces, produce coating shape and become oval grade for harmful effect.In order to improve the reduction of coating precision, the variation of coating shape, as shown in figure 26, need make elastic supporting part 18 taking the front end 3a of the coating needle 3 that contacts at first as fulcrum moves a certain distance.
Also can consider that and longer material such as, by material, rubber, the Compress Spring etc. of movement of cardinal extremity 3b of inclination, coating needle 3 by absorbing workpiece W soft like that forms elastic supporting part 18, absorb the movement of the cardinal extremity 3b of inclination, the coating needle 3 of workpiece W.
But as shown in Figure 27 (a), Figure 27 (b), the reaction force F1 front end 3a of coating needle 3 being applied from workpiece W is divided into and can be used for the power F2 of absorption dip and can be used for absorbing the power F3 that move position, compared with F2, F3 is minimum.Therefore, need to use and can move forward into position the elastic supporting part 18 that row absorbs with less power, but have following shortcoming: vibration effect when this elastic supporting part 18 is easily subject to coating action, in addition, elastic force is difficult to be back to original position a little less than.
In addition, also can consider that the elastic supporting part 18 that is difficult to the hardness that is subject to vibration effect degree by use strengthens pressing force, thereby strengthen the power that move position that absorbs, if but in the time that the state of the front end 3a of coating needle 3 inclination is pressed energetically, workpiece W may be damaged.
Therefore,, in present embodiment 11, provide a kind of coater unit that can stablize and be coated with accurately with lighter pressing force correction ink 11.
