Problems solved by technology

However, in this known recording apparatus, the speed at which each user mounts the ink cartridge to the mounting portion may vary from user to user, so that the recording apparatus obtains different determination results for different users.
For example, if the user installs the ink cartridge into the mounting section faster than a predetermined speed, or if the user initially inserts the ink cartridge into the mounting section and then partially removes the ink cartridge before finally fully inserting the ink cartridge into the mounting section, the sensor may detect an incorrect accurate information

Abstract

An ink cartridge includes a first signal blocking portion configured to selectively prevent a first signal from passing therethrough or to alter a path of the first signal. The ink cartridge also includes a second signal blocking portion configured to selectively prevent a second signal from passing therethrough or to alter a path of the second signal. The second signal blocking portion has a thickness determinative of whether the second signal blocking portion prevents the second signal from passing therethrough or alters 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.

Description

technical field [0001] The present invention generally relates to ink cartridges, ink cartridge sets, and ink cartridge identification systems. Background technique [0002] A known recording apparatus such as an inkjet recording apparatus includes an inkjet 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 paper when the known ink cartridge is mounted to the mounting portion. [0003] Another known recording device includes a carriage configured to accommodate another known ink cartridge. This known recording device is configured to determine the ink cartridge type by detecting the intensity of light reflected by the ink cartridge. While the carriage and cartridge are in motion, the intensity of the reflected light is measured by a sensor of the recording device, and from this intensity the type of cartridge is determined. Such a kn...
