  • Patent number: 7278696
    Abstract: 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.

  • Publication number: 20050018009
    Abstract: In a waste ink tank provided with a storing part in which waste ink ejected from an ink nozzle is stored, there are provided a waste ink inlet which catches the waste ink ejected from the ink nozzle and leads it to the storing part, and a sweeping mechanism for sweeping the waste ink that stays downward of the waste ink inlet. The sweeping mechanism comprises a scraper that slides, and a slant surface located downward of the waste ink inlet, on which the scraper slides, and an ink absorber for absorbing the waste ink ejected from the ink nozzle is provided on one side of the slide surface.
