摘要： An ink jet recording device comprises a recording head for ejecting pigmented ink in an ink chamber, an ink reservoir for circulating the pigmented ink between the ink chamber and the ink reservoir, and a replenishment tank for replenishing concentrated pigmented ink to the ink reservoir. The replenishment of the concentrated pigmented ink is effected by a piezoelectric element for reducing the volume of the replenishment tank upon receiving a driving signal. The concentration of colored particles in the concentrated pigmented ink is equal to the concentration of the colored particles in the ink droplet ejected from the ink chamber.

摘要： An electrostatic ink jet recorder of the present invention includes a head for ejecting ink, an ink reservoir storing the ink, and an ink feed pipe and an ink discharge pipe for circulating the ink between the head and the ink reservoir. The head has a first ink chamber communicated to the ink feed pipe, a second ink chamber communicated to the ink discharge pipe, a third ink chamber positioned at a higher level than the first and second ink chambers for ejecting the ink for printing, a siphon pipe communicating the first and third ink chamber and having a suction opening below an ink level in the first ink chamber, and an ink outlet pipe having an outlet opening above an ink level in the second ink chamber for delivering the ink from the third ink chamber to the second ink chamber. Delicate pressure variation in the head ascribable to the movement of the head is reduced in order to maintain pressure inside the third ink chamber for ejection stable.

摘要： An electrostatic ink-jet printing head in which ink containing charged toner particles in an insulating solvent is supplied from an ink reservoir, an electric field is applied to the ink to generate an electrostatic force, and the electrostatic force causes the toner particles to be ejected from ink ejecting ports. The electrostatic ink-jet printing head comprises a head block including a head block main body which defines an ink chamber and also including a base film which is assembled on the head block main body. The base film has ink ejecting ports and has a plurality of projections extending from one edge of the ejecting port into the ejecting port. The ejecting ports, ejecting electrodes and ejecting projections are collectively formed on a base film by a TAB technique, and by bending the base film at the ejecting ports having projections according to the shape of the head block main body.

摘要： An ink jet type head has a plurality of ink ejection electrodes in a form of parallel strips formed on a base. The ink ejection electrodes include first ejection electrode and second ejection electrodes provided adjacent to two sides of the first ejection electrode. There is provided a voltage driving unit for applying an ejection voltage for ink ejection to the first ejection electrode. In the voltage driving unit, the ejection voltage to cause the ink to be ejected is applied to the first ejection electrode and an auxiliary voltage ineffective to cause the ink to be ejected is applied to the second ejection electrodes. This enables the reduction of potential differences between the first and second ejection electrodes, thus suppressing movement of color particles of the ink between them.
