摘要： An ink jet head includes an ink supply path (11), a pressure chamber (10), an orifice and an oscillator (7). By bending a portion of the wall surface of the pressure chamber (10) by oscillation of oscillator (7), ink is emitted. A portion of the wall surface of pressure chamber (10) is formed by an oscillating plate (4) of resin, and a unimorph including an elastic plate (5) and oscillator (7) provided on oscillating plate (4). Sidewalls (25) separating the inside of pressure chamber (10) are provided, and the dimension between the sidewalls is made shorter than the dimension of the unimorph.

摘要： A photoconductive layer is formed on the entire outer peripheral surface of a light transmissive drum, and a conductive layer is formed on the photoconductive layer and is made up of a plurality of strip-like conductive portions. Provided around the drum are a tank for storing thermo-melting ink, a blade which removes surplus ink on the outer peripheral surface of the drum, a drier for drying the ink filling the gaps between the conductive portions in the conductive layers, a platen roller which presses against the outer peripheral surface of the drum with a sheet of recording paper in between, and a light source which is provided inside the drum, facing the inner peripheral surface thereof. When the light source is selectively operated in accordance with image information, current is made to flow between the conductive portions in the conductive layer via the photoconductive layer at image recording areas, thus causing the ink filling the gap to be transferred to the recording paper.

摘要： An ink jet recording device has heating device (14a, 14b, 15a, 15b, 19, 20) for heating ink at a suction pipe (10), a suction pump (12) or a cap member (9). With this structure, an unsatisfactory operation of the ink jet recording device due to coagulation of ink can be prevented even when heat melting ink, or ink presenting plastic-flowability at the ordinary temperature, is used for the ink jet recording device.

摘要： An ink-jet recording head device capable of ejecting an ink from an orifice (34) opened on a slit (32), the ink being fed from an ink feeding port provided at a lower location than the orifice by means of pressure generated in response to an electrical signal, includes an ink conducting path (35, 35a, 35b, 35c) for communicating the ink feeding port with the slit. The ink conducting path includes a first conducting path (35, 35a, 35c) formed to conduct the ink from the ink feeding port to the upper place than the slit and then to the slit.
