摘要： 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.

摘要： In a liquid jet recording apparatus comprising a liquid jet section including orifice means for discharging a liquid to form flying droplets and liquid path means communicating with said orifice means and having as a part an energy acting portion for causing the energy to act on the liquid to form said flying droplets, and a liquid chamber communicating with said liquid path means and containing the liquid supplied to said liquid path means, the apparatus further comprises an air vent path formed in a member defining the liquid jet section and used to extract air from said liquid chamber, the air vent path has an inlet opened to the liquid chamber and an outlet formed on the liquid jet section, and the air vent path is defined by a groove formed on a plate by etching, on which plate groove means defining the liquid path means is similarly formed.
