摘要： An inkjet recording device of the present invention includes an inkjet recording head, a first wiper, a first movement component and a control component. The inkjet recording head ejects ink droplets from a plurality of nozzles formed in a nozzle face. The first wiper abuts against the nozzle face and wipes the nozzle face. The first movement component relatively moves the first wiper, with respect to the nozzle face, along the nozzle face. The control component controls ejection of ink droplets from the nozzles and controls the first movement component. The control component moves the first wiper relative to the nozzle face while the control component causes ink droplets to be ejected from the nozzles at least toward the first wiper, causing the nozzle face to be wiped.

摘要： In a printer head comprising a print element (12) and a protecting member (32) which is for protecting a printing end (24) of the print element, the protecting member is movable in a predetermined direction to place a free end (34) thereof at a first and a second position. The printing end is movable between a rest position and an activated or printing position in a first sense of the predetermined direction. When placed in the first position, the free end is substantially flush with the printing end put in the rest position so that the protecting member effectively protects the printing end. When the protecting member is moved in a second sense opposite to the first sense, the free end is retracted from the first position in the second sense to be placed at the second position so that the printing end can be readily machined without being obstructed by the protecting member. Preferably, the protecting member is rendered integral with a holding member (26) for holding the print element so that the printing end is movable between the rest position and the activated position.

摘要： A liquid droplet ejecting unit is disclosed wherein plural liquid droplet ejecting sub-units are provided which are arrayed in a direction substantially perpendicular to a conveying direction of a recording medium. Further, plural valves are provided which connect the respective liquid droplet ejecting sub-units and a liquid feed path. The valves comprise a valve body having an inlet port and an outlet port, and a floating member. The floating member is larger in radius than the inlet port and smaller in radius than the outlet port and has a lower specific gravity that the liquid. Thus, the floating member is floated in the liquid in the valve body and capable of closing the inlet port. An image forming apparatus using such a liquid droplet ejecting unit is also disclosed.

摘要： An ink jet recording apparatus according to the present invention comprises an ink jet recording head for ejecting ink drops and a differential pressure valve provided in an ink feeding line connected to the ink jet recording head, the differential pressure valve generating a head back pressure in the ink jet recording head when ejecting no ink drop. Thus, the degree of freedom for the position of arrangement of an ink reservoir such as an ink tank connected to the ink feeding line is remarkably increased. Accordingly, it is possible to realize an ink jet recording apparatus of reduced size.
