ABSTRACT:
An ink outlet and a pushing pin are formed on the bottom of a case of an ink cartridge. A fine-textured filter is put on inside of the ink outlet. A carriage is provided with an ink holding section at an upper end of an ink supply tube and a pressing section that is connected to the ink supply tube. As the ink cartridge is mounted on the carriage, a porous member of the ink holding section is pressed onto the filter, whereas the pushing pin pushes the pressing section to deform elastically. Then pressure inside the ink supply tube is raised to feed the ink reversely into the porous member, so the ink inside the ink supply tube is joined to the ink inside the case, reducing pressure loss through the filter.
