Definitions

  • the present invention relates generally to ink cartridges, sets of ink cartridges, and ink cartridge determination systems.
  • a known recording apparatus such as an ink-jet recording apparatus, includes an ink-jet recording head and a mounting portion to which a known ink cartridge is mounted.
  • the known recording apparatus is configured to dispense ink from a plurality of nozzles to record an image on a sheet of paper.
  • Another known recording apparatus includes a carriage configured to receive another known ink cartridge.
  • This known recording apparatus is configured to determine a type of the ink cartridge by sensing an intensity of light reflected by the ink cartridge. When the carriage and the ink cartridge move, the intensity of the reflected light is measured by a sensor of the recording apparatus, and based on the intensity, the type of the ink cartridge is determined.
  • a sensor of the recording apparatus is described in US2005/0024454 A1 for example.
  • Yet another known recording apparatus includes a mounting portion which is separate from a carriage, and this known recording apparatus is configured to determine the type of another known ink cartridge when the ink cartridge is mounted to the mounting portion. Specifically, when the ink cartridge is mounted to the mounting portion, the recording apparatus detects the presence or absence of a signal blocking portion of the ink cartridge, and the type of the ink cartridge is determined based on the presence or absence of the signal blocking portion.
  • a known recording apparatus is described in US 2005/0195225 A1 for example. Nevertheless, in this known recording apparatus, the speed with which various users mount the ink cartridge to the mounting portion may vary from user to user, such that the recording apparatus may reach different determinations from user to user.
  • the senor may detect inaccurate information if the speed with which the user mounts the ink cartridge to the mounting portion is greater than a predetermined speed, or if the user begins to insert the ink cartridge into the mounting portion and then partially removes the ink cartridge before finally fully inserting the ink cartridge into the mounting portion, the sensor may detect inaccurate information if the speed with which the user mounts the ink cartridge to the mounting portion is greater than a predetermined speed, or if the user begins to insert the ink cartridge into the mounting portion and then partially removes the ink cartridge before finally fully inserting the ink cartridge into the mounting portion, the sensor may detect inaccurate information if the speed with which the user mounts the ink cartridge to the mounting portion is greater than a predetermined speed, or if the user begins to insert the ink cartridge into the mounting portion and then partially removes the ink cartridge before finally fully inserting the ink cartridge into the mounting portion, the sensor may detect inaccurate information if the speed with which the user mounts the ink cartridge to the mounting portion is greater than a predetermined speed, or
  • a technical advantage of the present invention is that the configuration of the ink cartridge allows a recording apparatus to accurately determine information associated with the ink cartridge independent of the speed with which the user mount the ink cartridge to the printer and regardless of whether the user begins to insert the ink cartridge into the printer and then partially removes the ink cartridge before finally fully inserting the ink cartridge into the printer.
  • an ink cartridge comprises a first signal blocking portion, a second signal blocking portion, and a third signal blocking portion.
  • the first signal blocking portion is configured to either prevent a first signal from passing therethrough or to alter a path of the first signal when the first signal blocking portion receives the first signal
  • the second signal blocking portion is configured to either prevent a second signal from passing therethrough or to alter a path of the second signal when the second signal blocking portion receives the second signal.
  • the third signal blocking portion is configured to either prevent the second signal from passing therethrough or to alter a path of the second signal when the third signal blocking portion receives the second signal.
  • a set of ink cartridges comprises first and second ink cartridges.
  • the second signal blocking portion of the first ink cartridge has a thickness configured to prevent the second signal from passing therethrough or alter the path of the second signal at a time that the first signal blocking portion initially prevents the first signal from passing therethrough or alters the path of the first signal.
  • the second signal blocking portion of the second ink cartridge has a thickness configured not to prevent the second signal from passing therethrough or alter the path of the second signal at the time that the first signal blocking portion initially prevents the first signal from passing therethrough or alters the path of the first signal.
  • an ink cartridge determination system comprises the ink cartridge and a recording apparatus.
  • the recording apparatus comprises a cartridge mounting portion configured to mount the ink cartridge, a first sensor disposed in the cartridge mounting portion and comprising a first signal-emitting element configured to emit the first signal and a first signal-receiving element configured to receive the first signal, and a second sensor disposed in the cartridge mounting portion and comprising a second signal-emitting element configured to emit the second signal and a second signal-receiving element configured to receive the second signal, and a determiner.
  • the first signal blocking portion is configured to either prevent the first signal from passing therethrough or to alter the path of the first signal at least during a mounting of the ink cartridge to the cartridge mounting portion.
  • the first signal blocking portion is configured to either prevent the second signal from passing therethrough or to alter the path of the second signal during the mounting of the ink cartridge to the cartridge mounting portion.
  • the third signal blocking portion is configured to either prevent the second signal from passing therethrough or to alter the path of the second signal when the mounting of the ink cartridge to the cartridge mounting portion is completed.
  • An intensity of the second signal received by the second signal-receiving element when the second signal is prevented from passing through the second signal blocking portion or the third signal blocking portion or the path of the second signal is altered by the second signal blocking portion or the third signal blocking portion is different from an intensity of the second signal received by the second signal-receiving element when the second signal is not prevented from passing through the second signal blocking portion or the third signal blocking portion or the path of the second signal is not altered by the second signal blocking portion or the third signal blocking portion.
  • the determiner is configured to determine information associated with the ink cartridge based on the intensity of the second signal received by the second signal-receiving element at a time that the intensity of the first signal received by the first signal-receiving element initially changes during the mounting of the ink cartridge to the cartridge mounting portion. Moreover, the determiner may be configured to determine an amount of ink in the ink chamber based on the intensity of the second signal received by the second signal-receiving element when the mounting of the ink cartridge to the cartridge mounting portion is completed.
  • information associated with the ink cartridge is accurately determined.
  • the amount of ink in the ink chamber may be determined.

At this time, the signal level of the sensor signal outputted from the optical sensor 230 changes from HIGH to LOW.

Because the signal blocking portion 199 has the side walls 198, the duration during which the light is blocked or altered by the signal blocking portion 199 is greater than the duration during which the light is blocked or altered by the signal blocking portion 189. Specifically, at the time T1, the side walls 198 are still in the optical path 231.
