Abstract
In recording information patterns on the surface of an article conveyed by a conveyer, a distortion of recorded patterns occurs when the speed of the conveyer varies. In the present invention, the speed of the conveyer is detected to control the collection of dot-forming ink droplets thereby preventing the occurrence of the distortion of the recorded patterns.
