Abstract
Liquid droplets of large diameter and small diameter are alternately emitted from a jet nozzle and are deflected in accordance with control information so that the liquid droplets of large diameter and/or the liquid droplets of small diameter can be directed toward a recording sheet as desired. This system is especially effective in controlling ink droplets in an ink jet recorder using ink.
