The soft and longer material like that such as compression spring forms elastic supporting part 18, come absorb workpiece W inclination, coating needle 3 base
Hold 3b movement.
However, as shown in Figure 27 (a), Figure 27 (b), the reaction force F1 quilts of the front end 3a applications from workpiece W to coating needle 3
It is divided into the power F2 that can be used for absorption dip and the power F3 for absorbing position movement can be used for, compared with F2, F3 is minimum.Therefore, need to make
With can be with less power to the elastic supporting part 18 that be absorbed of position movement, but have the following disadvantages：This elastic supporting part
18 vibration effect when easily being acted by coating, it is difficult in return in addition, elastic force is weaker to original position.
In addition, it is also contemplated that by using the elastic supporting part 18 for the hardness for being difficult to influence degree vibrated strengthen by
Pressure, so as to strengthen the power for absorbing position movement, if but when the inclined states of front end 3a of coating needle 3 press energetically, workpiece W
May be damaged.
Therefore, in present embodiment 11, there is provided a kind of to be stablized with lighter pressing force and be accurately coated with
Correct the coater unit of ink 11.
