Abstract
An ink cartridge attachment/detachment device that loads an ink cartridge into a main body of a recording apparatus by sliding the ink cartridge into includes an ejection lever and an urging force adjustment device. The ejection lever contacts the ink cartridge and urges the ink cartridge using an urging force of an urging device in an ejecting direction in which the ink cartridge is ejected when the ink cartridge is loaded or when the ink cartridge is ejected. The urging force adjustment device changes a ratio of a force with which the urging device urges the ejection lever in a pivotal direction in which the ejection lever is pivoted to a force with which the urging device urges the ejection lever in a radial direction about a pivotal fulcrum of the ejection lever. The urging force adjustment device reduces the force with which the urging device urges the ejection lever in the radial direction as the ejection lever is pivoted in the ejecting direction, and the urging force adjustment device increases the force with which the urging device urges the ejection lever in the radial direction as the ejection lever is pivoted in a loading direction in which the ink cartridge is loaded.
