  • Patent number: 7731328
    Abstract: A wiper, a cleaning device, and an inkjet image forming device including the wiper and the cleaning device. The cleaning device includes a carrier moving in a lengthwise direction of a nozzle unit, the length of the nozzle unit corresponding to a width of a printing medium, a driving element moving the carrier forwards and backwards, and a wiper mounted on the carrier and removing ink adhered to the nozzle unit, wherein the wiper includes a belt member which is supported by a plurality of pulleys and circularly moves along a predetermined path and a cleaning member which is attached to an outer circumference of the belt member and removes the ink adhered to the nozzle unit while rotating in contact with the nozzle unit. Accordingly, an absorption capacity of the wiper is increased using the belt type wiper. Furthermore, since the absorption capacity of the wiper is increased, a replacement cycle for replacing the wiper is extended, thereby increasing the life span of the wiper.

  • Patent number: 7726772
    Abstract: A liquid ejection apparatus including a liquid ejection head, a liquid receiver, a liquid receiver movement mechanism, and a lid body is provided. The liquid ejection head has a nozzle surface. The nozzle surface includes a nozzle opening. The liquid ejection head ejects a liquid from the nozzle surface. The liquid receiver has an opening provided in correspondence with the nozzle surface of the liquid ejection head. The liquid receiver is capable of receiving the liquid ejected as a waste liquid from the nozzle opening of the liquid ejection head through the opening of the liquid receiver. The liquid receiver movement mechanism moves the liquid receiver between a receiving position at which the opening of the liquid receiver opposes the nozzle surface of the liquid ejection head and a non-receiving position spaced from the receiving position. The lid body is arranged at the non-receiving position.

  • Patent number: 7726771
    Abstract: An inkjet printer that has a printhead with an elongate orifice plate and a surface that surrounds the elongate orifice plate, a platen that partially defines a media path extending passed the printhead, a capping member with a seal for sealing engagement with the surface that surrounds the printhead, and a static solenoid for moving the capping member in a direction perpendicular to the longitudinal extent of the elongate orifice plate. During use, the printhead, the media path and the platen all remain fixed relative to each other, and the capping member is movable through the media path. Providing a sealing surface around the orifice plate that is configured to engage the cap and seal the printhead requires less manufacturing precision than a capping mechanism that directly engages the orifice plate. Production efficiencies from lower precision assembly have particular significance for high volume products.

    Abstract: A nozzle protecting device 30 of an ink jet type recording apparatus has a cap 46 which covers nozzles of a recording head and a cap support member 47 which is connected to the cap 45 via a spring member 80. The distance between the cap 46 and the cap support member 47 can be changed by elastic deformation of the spring member 80. A vent hole 54 is formed in the cap 46. A valve seat 56 which covers the terminal portion of the vent hole 54 is provided. A valve body 58 is rotatably attached to the lower portion of the cap 46. The valve body 58 selectively abuts on and parts from the valve seat 56 in accordance with the distance between the cap 46 and the cap support member 47. As a result, the inside of the cap 46 is opened and closed to air via the vent hole 54.
