Patent number: 8162425Abstract: An image recording apparatus improves the operating efficiency while preventing trouble due to the contact of a recording medium with a discharging surface of a recording head. A distance sensor for detecting the distance of the leading edge of a sheet from a conveying surface is provided upstream from the inkjet head in the conveying direction of the sheet. A gap control unit controls a frame moving mechanism to move the inkjet head up so that a gap between the discharging surface and the conveying surface increases when the distance detected by the distance sensor is above a first distance, and the gap distance may be increased by different amounts depending on the distance detected by the distance sensor. A discharging control unit controls the inkjet head to discharge ink droplets after the gap is increased.Type: GrantFiled: March 28, 2008Date of Patent: April 24, 2012Assignee: Brother Kogyo Kabushiki KaishaInventors: Shigeki Kato, Katsuaki Suzuki, Masahiro Nishizaki, Koji Nakayama

Patent number: 8011746Abstract: When a DNA ink printing mode is selected, a serial number and a pattern data of DNA is read from an IC tag of a DNA ink cartridge and a fingerprint of a printing person is read by a fingerprint authenticating unit. The pattern of the fingerprint and DNA which have been read are verified with the pattern data of fingerprints and DNA in a memory and personal authentication is carried out. Thereafter, a DNA ink is jetted on to a recording paper, and printing of an image by an image forming ink is carried out. By carrying out printing by such a method, it is possible to specify the printing person who has created the printed matter.Type: GrantFiled: December 28, 2007Date of Patent: September 6, 2011Assignee: Brother Kogyo Kabushiki KaishaInventors: Hiroto Sugahara, Hiroaki Yazawa, Masahiro Nishizaki, Motohiro Momozaki

Patent number: 7931361Abstract: An ink-jet head according to the present invention includes a passage component, a filter, and a sealing member. The passage component defines an ink passage which includes a middle hole having an opening. The filter partitions the middle hole of the passage component into a first space and a second space. The sealing member seals the opening. The sealing member has a first region which is opposed to the filter with respect to the vertical direction. The filter is mounted to the passage component in such a manner that ink passing through the filter flows from the first space upward into the second space. A surface of the first region of the sealing member facing the ink passage has a portion which is inclined relative to a horizon.Type: GrantFiled: December 28, 2007Date of Patent: April 26, 2011Assignee: Brother Kogyo Kabushiki KaishaInventor: Masahiro Nishizaki
