Abstract

PURPOSE:To obtain the ink jet recording unit simple in construction, having no restriction in moving scanning and easy to exchange by a method wherein an ink reservoir is formed integral with a head equipped with an oscillator, ink chamber and a nozzle to make them into one unit. CONSTITUTION:The ink reservoir 8 is formed at the lower position of the nozzle 2 in one side of the rectangular parallelopiped head body 1 equipped with the oscillator 4, the ink chamber 3 and the nozzle 2 and a membrane filter 9 is provided at the bottom surface thereof. The lower part of the ink reservoir 8 and an ink supplying chamber 10 provided at the nozzle section 2 are connected by a supplying path 11. The head body 1 thus constituted is made into one unit and is connected to the other unit by only electrical connections, therefore, it is very easy to attach to and detach from a carrier. Ink is fed from the ink reservoir 8 to the ink liquid chamber 3 sufficiently by capillarity and the setting of the ink at the nozzle section 2 upon resting may also be eliminated. Bubbles will never invade into the ink liquid chamber 3 since thay are removed by the membrane filter 9 at the bottom surface of the ink reservoir 8.
