Definitions

  • the present invention relates generally to ink cartridges.
  • the present invention is directed towards ink cartridges which may be used in combination with ink jet printers.
  • a known ink jet printer is configured to dispense ink onto a sheet of paper to record an image on the sheet of paper.
  • the known ink jet printer has a recording head.
  • the recording head is configured to selectively eject ink from nozzles to the sheet of paper.
  • a known ink cartridge is configured to be removably mounted to the ink jet printer.
  • the ink cartridge has an ink chamber configured to store ink therein, and ink is supplied from the ink chamber to the recording head when the ink cartridge is mounted to the ink jet printer.
  • the ink cartridge has a movable member positioned in the ink chamber.
  • the movable member is configured to pivot based on the amount of ink stored in the ink chamber.
  • an end of the movable member moves from a first position at which the end of the movable member is detected by a detector e.g., an optical sensor, to a second position at which the end of the movable member is not detected by the detector. Consequently, whether the ink chamber has a sufficient amount of ink stored therein may be determined based on the position of the end of the movable member.
  • the movable member is submerged in ink when the ink chamber has an amount of ink which is substantially greater than a sufficient amount of ink. As the ink in the ink chamber gradually decreases, the movable member gradually becomes exposed above the surface of the ink. When the movable member is exposed from the surface of the ink, a web-shaped film of ink or a balloon-shaped film of ink may be formed between the movable member and inner wall of the ink chamber. The film may inhibit or restrict the pivotal motion of the movable member, and the end of movable member may not be detected accurately. For example, when the movable member attempts to pivot away from the surface of the ink, the film may draw the movable member towards the inner wall of the ink chamber.
  • an ink cartridge for supplying ink to an inkjet recording device.
  • the ink cartridge comprises a case forming a housing space for housing an ink reservoir element on the inside and a replaceable ink reservoir element storing ink and placed in the housing space.
  • the ink reservoir element comprises an ink supply part for supplying ink to an inkjet recording device and an irradiated part structured to be placed between two portions of an optical sensor of the inkjet recording apparatus and to be irradiated with light. A remaining ink quantity can be detected by the operation of a sensor arm.
  • an ink cartridge including a movable member which includes a sliding member and a float portion.
  • the sliding member includes a signal blocking portion, and the signal blocking portion is configured to move in a first direction from a first position within a translucent portion to a second position based on the amount of ink within the ink chamber.
  • the float portion is operationally coupled to the sliding member, and the float portion is disposed within the ink chamber. The float portion is configured to move independent of the first portion in a second direction from a third position to a fourth position based on the amount of ink within the ink chamber.
  • an ink cartridge comprising a sensor arm which is provided inside the ink tank where ink is stored and which moves along a set displacement path as the ink stored inside the ink tank decreases.
  • a diffusion surface is provided on a portion of the surface of the sensor arm. Small irregularities are formed on the diffusion surface so as to generate a capillary force.
  • the diffusion surface consists of a base surface and a plurality of projecting parts projecting from the base surface. Base surface and projecting parts are connected at an angle so as to form corner parts. Furthermore, capillary force generating areas formed between adjusting projecting parts are linked to other capillary force generating areas.
  • a technical advantage of the present invention is that a movable member readily may pivot in a direction away from a surface of ink.

In this case, the upper ends 159 of the supporting portions 189 extend substantially in parallel with the direction of extension of the second sub-portion 63 (see Fig. 16 ) of the arm 70.

  • leading end surface 58 has an S-shape. Consequently, the edge of the leading end 59 of the reinforcing plate 53 is not extended linearly in the direction of thickness 40. Therefore, the tendency of an ink film to be formed along the leading end 59 is reduced.
