  • Publication number: 20160144627
    Abstract: Provided is a cleaning device that can reduce maintenance-time while injecting a cleaning solution into a gap between head modules so that the cleaning solution or the like is not sucked into an inkjet head. The position of the inkjet head relative to a spray-nozzle is moved in one direction. When relative movement is performed, the relative movement is temporarily stopped or moving speed of the relative movement is reduced at a position where the gap between the head modules faces at least the spray-nozzle. The cleaning solution is sprayed to the gap at a time when the relative movement is temporarily stopped or when the moving speed of the relative movement is reduced. A removing member removing the cleaning solution present in the gap, is provided at a position separated from the spray-nozzle in the one direction by a distance of n times a pitch of the gaps.

  • Patent number: 9308730
    Abstract: The present invention provides a nozzle face wiping device and an image recording device that can switch whether to wipe out a nozzle face by a simple mechanism. According to one mode of the present invention, it is possible to brake the running of the wiping web by the braking device on the upstream side (supply shaft side) of the pressure member. In a case where the running direction of the wiping web wound around the pressure member and the relative movement direction of the nozzle face are the same, it is possible to prevent the wiping web from being forcefully drawn out from the supply shaft by braking the running of the wiping web by the braking device. By this means, it is possible to wipe out the nozzle face from two directions.

  • Patent number: 8947562
    Abstract: A zoom lens has first through fourth lens groups from the object side to the image side, and changes the magnification by changing their intervals. The first and third lens groups and the second and fourth lens groups have negative and positive powers, respectively. When changing the magnification from the wide-angle end to the telescopic end, the interval between the first and the second lens groups is reduced. The first lens group includes a reflective optical element. The second lens group includes at least two lenses, and the lens nearest to the image is a single plastic positive lens. The third lens group is configured by a single plastic negative lens. When the focal length of the single lens nearest to the image in the second lens group is defined as f2L and the focal length of the third lens group is defined as f3, “0.60<|f2L/f3|<1.60” is satisfied.
