    • An image recording apparatus comprising an array of styli regularly electrically connected at intervals of an integer of styli and an array of opposite electrodes each of which is disposed opposite to a plurality of styli, and either the styli or the opposite electrodes are made of a magnetic material. A protuberance of a magnetofluidic material, which is called magnetic ink herein, is formed on the tip of each stylus or each opposite electrode of magnetic material. A pluse signal having a constant frequency is applied in dot sequential fashion to one of the stylus array and the opposite electrode array, and a signal corresponding to an image is applied to the other, so that the protuberances of the magnetic ink formed on the selected styli or opposite electrodes in the stylus array and opposite electrode array applied with the two signals simultaneously fly toward a recording surface to obtain a desired image thereon.
    • 一种图像记录装置,其特征在于,包括以一定的电针间隔规则地电连接的触针阵列和相对电极的阵列,每个相对电极与多个测针相对设置,并且所述测针或相对电极由磁 材料。 在每个触针的尖端或磁性材料的每个相对电极上形成磁流体材料的突起,其在此称为磁性墨。 具有恒定频率的脉冲信号以点顺序的方式施加到触针阵列和相对电极阵列中的一个,并且对应于图像的信号被施加到另一个,使得形成在所选择的磁性墨水上的突起 触针阵列中的测针或相对电极和施加有两个信号的相对电极阵列同时朝向记录表面飞行以在其上获得期望的图像。
