摘要： An ink jet printer having a print head which comprises a front nozzle member having a front channel, a housing secured to the front nozzle member, and a rear nozzle member which defines with the housing a liquid chamber and further defines with the front nozzle member a laminar airflow chamber. The rear nozzle member has a forwardly projecting nozzle and a rear channel extending from the liquid chamber through the projecting nozzle in axial alignment with the front channel to form a meniscus at the front end. The airflow chamber is connected to an air supply for directing air to a point between the front and rear channels so that it creates a sharp pressure gradient along a path therebetween. A dead air region is created in a location adjacent the exit end of the rear channel to cause the meniscus to take a dome-like shape which is stabilized against vibrations and transients. An electric field gradient is established between the front channel and the meniscus to cause the latter to extend toward the front channel and expelled through the front channel.

摘要： In a nonimpact printer having a reciprocable printer head, ink is supplied to the head through a pair of identical, flexible conduits which are connected from first and second spaced apart outlets of an ink container. The container is not air tight with the outside so that it can act as a pressure absorber. Each of the first and second conduits have a sufficient length to allow the head to reciprocate along the length of a platen with end of each conduit moving therewith to cause pressure variations to occur in the conduits when the printer head varies its speed of movement. By virtue of the pressure absorbing action of the liquid container, the pressure variations are nullified and the printer head is supplied with constant pressure ink.
摘要翻译：在具有可往复打印头的非打印机打印机中，油墨通过一对相同的柔性管道供应到头部，该管道从墨水容器的第一和第二间隔开的出口连接。容器与外部不是气密的，因此它可以用作减压器。第一和第二导管中的每一个具有足够的长度，以允许头部沿着压板的长度往复运动，每个导管的端部随着其移动而在打印头改变其运动速度时导致管道中发生压力变化。由于液体容器的压力吸收作用，压力变化无效，打印机头被供给恒压油墨。

摘要： An ink ejection recording apparatus is disclosed which comprises a plurality of ink ejection heads commonly connected to an ink tank, each of the ink ejection heads having an ink nozzle through which minute ink droplets are discharged in accordance with an electric signal and an air nozzle opposing to the ink nozzle and adapted for forming an air stream which accelerates the ink droplets towards a recording medium so as to record an image on the recording medium by means of the droplets. The ink ejection heads are arranged at different heights and the ink ejection heads have different levels of balance pressure so that the levels of the ink pressure acting on the ink nozzles of the ink ejection head are equalized in the operating state of the apparatus. Pressure relieving means are provided for relieving pneumatic pressure applied to the ink ejection heads and to the ink tank and being arranged such that relief of pressure from said ink tank is conducted after relief of pressure from said ink ejection heads.

摘要： An ink jet recording apparatus has an ink jet unit from which tiny independent ink droplets, suspended by a flow of air, are made to fly towards a recording medium, thereby recording information on the medium. The apparatus has a heat washing unit disposed at a position beyond one end of a recording medium mounting portion, so that the ink jet unit which has been moved to this position after completion of the recording operation is washed by the head washing unit which is movable towards and away from the ink jet unit at this position, whereby a high stability and reliability of the ink jet recording are ensured for a long period of time without suffering from clogging of nozzles or contamination of the recording medium. The stability and reliability are further enhanced by the simultaneous use of an ink mist suction unit which sucks ink mist around the ink jet unit and an anti-clogging unit which prevents clogging of the nozzles.
摘要翻译：一种喷墨记录装置具有一个喷墨单元，使由空气流悬置的微小的独立墨滴从该喷墨单元朝向记录介质飞行，从而在介质上记录信息。该设备具有设置在超过记录介质安装部分的一端的位置处的热洗单元，使得在完成记录操作之后移动到该位置的喷墨单元被可移动的头部清洗单元在该位置处朝向和远离喷墨单元，从而长时间地确保喷墨记录的高稳定性和可靠性，而不会受到喷嘴堵塞或记录介质的污染。通过同时使用在喷墨单元周围吸墨墨水的墨雾吸引单元和防止喷嘴堵塞的防堵塞单元来进一步提高稳定性和可靠性。
