Abstract
A cartridge is detachably mountable to a holder of an ink jet recording apparatus, so as to be freely reciprocatable to scan across a recording medium and record thereon by discharging ink. The cartridge is defined by a cartridge main body, and is provided with a recording head for discharging ink from plural nozzles formed in parallel on a lower face of the cartridge main body facing the recording medium. A front face of the cartridge main body is provided with an electrical connection portion having cartridge electrodes, which are electrically connectable with corresponding electrodes of the holder. A rear face opposite to the front face is provided with an ink connection portion connectable to corresponding supply ports which supply ink to the recording head from a main tank installed elsewhere on the ink jet recording apparatus. With the cartridge thus structured, the force exerted for connection to the supply port does not affect the precision with which the cartridge is mounted on the holder.
