Patent number: 8807714Abstract: An ink-jet recording apparatus has a print head 13 incorporating: a nozzle 20, which vibrates ink at a constant cycle, jets out the ink, and atomizes the ink; an electrification electrode 26, which electrify an ink particle 19; and deflection electrodes 27b, which deflect the electrified ink particle in a main scanning direction. The print head 13 carries out printing by causing the ink particle to fly to a printing workpiece W conveyed by a conveyer 15. Flying time of the ink particle in a printing distance La between the printing workpiece W and the print head 13 is calculated, timing of an electrification signal supplied to the electrification electrode 26 is controlled in accordance with the flying time, and a printing position to the printing workpiece W is set. Thus, printing can be carried out at a predetermined position to the printing workpiece W, and printing quality can be enhanced.Type: GrantFiled: June 24, 2009Date of Patent: August 19, 2014Assignee: Hitachi Industrial Equipment Systems Co., Ltd.Inventors: Takuya Moriai, Nobuhiro Harada, Masahiko Sakuraba

Patent number: 8136900Abstract: An inkjet recording apparatus includes a nozzle, a charging electrode, a deflecting electrode, a storage device, and an authentication device. The nozzle atomizes a supplied ink into ink particles by exciting and ejecting the supplied ink. The charging electrode electrically charges the ink particles. The deflecting electrode forms an electric field that deflects the ink particles electrically charged. The storage device storing therein a program(s) that implements a predetermined printing function(s). The predetermined printing function(s) becomes executable upon connection of an authentication key to the authentication device.Type: GrantFiled: February 10, 2009Date of Patent: March 20, 2012Assignee: Hitachi Industrial Equipment Systems Co., Ltd.Inventors: Michio Iwasaki, Masahiko Sakuraba, Nobuhiro Harada, Shinichi Kobayashi
