ABSTRACT:
An ink jet recording apparatus is designed to prevent leakage of ink from an ink tank cartridge with recording ink stored therein when the cartridge is removed. A flexible ink bag is sandwiched between an upper plate and a lower plate so that the-upper plate can be moved as the ink bag contracts as the ink is consumed. When the ink is almost gone, the upper plate is held by a latch on the lower plate, and movement of the ink bag is suppressed. Leakage of ink from a stopper that provides access to the ink bag is prevented by sealing members on the upper and lower plates. Thus, when the cartridge is replaced, no ink will be applied.
