Patent number: 7278696Abstract: An inkjet recording apparatus ejects ink from recording heads to a recording paper, thereby attaching the ink to the medium for recording. The apparatus includes a carriage driving motor, a transfer motor, a scanner which reciprocates a carriage having the recording heads in a scanning direction, and a transfer machine. The transfer machine transfers the recording paper in a transfer direction perpendicular to the scanning direction. Both of the motors are located at approximately the same place in an ejecting direction of ink from the heads to the paper, and at the same height of a transfer path of the paper or on the carriage side with respect to the transfer path.Type: GrantFiled: March 7, 2006Date of Patent: October 9, 2007Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Tetsuya Matsuzaki, Shinichi Kitamura, Hiroyuki Matsuba, Kensei Otsubo
