LIRAY / Spray Nozzle

Unless it is a case of scribbling, the coloring work with a can spray requires prudence.

In the SLR camera, when the shutter button is pushed slightly, it collects the information to photograph, and when it is pushed more strongly, it photographs the information. This was applied to the spray; that is, when the button is slightly pushed, it shoots the LED light so that it can be seen in advance which area will be colored when the paints are actually sprayed. If they can check it from the laser and then sprays, they can do the work far more precisely and save the amount of paints that could have been wasted.
