    摘要: An ink jet recorder includes a plurality of recording elements which are arranged corresponding to each of a plurality of ejection outlets for ejecting ink in accordance with driving signals, a plurality of ejection passages corresponding to the ejection outlets and connected to a common chamber, a plurality of driving blocks formed by dividing the recording elements by predetermined number of units in the arrangement order, control elements for each of the driving blocks and for controlling the recording elements associated with each driving block in a simultaneous driving manner, a selection unit for selecting the driving block to be driven in order that at least adjacent driving blocks are not driven in sequence, and a supply unit for supplying driving signals to the driving block selected by the said selecting unit. With this arrangement, ink in ejection passages associated with a driving block adjacent the selected driving block will not be significantly affected when the selected driving block is driven.

    摘要: An ink jet recording apparatus of the present invention has an ink jet recording head having an orifice from which an ink drop is ejected and an energy generation means for ejecting an ink fluid in the orifice. A first electrode is formed in the orifice and is connected electrically to the ink fluid. A second electrode is formed in an opposite position to the orifice with a designated distance from the orifice. A voltage controller applies a first voltage during a time period from a time when an ink fluid is ejected from the orifice to a time when the ink fluid is separated in 2 or more ink drops during traveling, and immediately after applying the first voltage, applies a second voltage which has an identical polarity to a polarity of the first voltage and has an absolute value less than an absolute value of the first voltage.

    摘要: In an ink jet recording apparatus in which a filter is placed in an ink supply route, when an ink flow is formed in the ink supply route by ink ejection during recording operations and so on, a valve does not contact firmly to the filter, but when an ejection recovery operation is performed and an ink flow velocity increases, the valve contacts firmly to the filter and covers up a part of the filter. With this structure and operation, the effective cross-section area of the filter decreases and hence, a given quantity of pressure difference is produced between the upstream side and the downstream side of the filter. As a result, bubbles unable to pass through the filter at recording operations can pass through the filter when ejection recovery operations are performed.
