摘要： Disclosed is an ink jet head driven by a drive IC for ejecting an ink droplet having conductivity, comprising a chamber for storing ink, a nozzle plate attached to the chamber, an actuator provided with an electrode electrically contacting ink in the chamber and activated by a current flowing through the electrode from a power supply, a conductive plate including an opening and glued to the nozzle plate such that the nozzle is exposed through the opening, and a current limiter limiting the current when the ink is purged from the nozzle during a period other than that of ink being ejected. Even if the purge is repeatedly carried out, an extraordinarily rising in temperature of the drive IC and resultant breakdown of the IC can be prevented.

摘要： A single recording head is provided which includes a set of plural head units each having a substrate and plural recording elements arranged on the substrate, whereby a line type recording head which is long in a main scanning direction can be manufactured easily and in high yield. The head units are arranged to be inclined so that the rows of recording elements are inclined in the main scanning direction, whereby the arrangement pitch of recording elements in a sub scanning direction is narrowed to permit a high definition recording. The inclined arrangement of the head units, moreover, is made so that the recording elements located at the same position on the substrates of separate head units lie on the same main scanning line, whereby an increase of size in the sub scanning direction is prevented and a reduction of the entire size is attained.

摘要翻译： 提供单个记录头，其包括一组多个头单元，每个头单元具有基底和布置在基底上的多个记录元件，由此可以容易且高产率地制造长主扫描方向的线型记录头。 头单元被布置成倾斜，使得记录元件行在主扫描方向上倾斜，由此使记录元件在副扫描方向上的排列间距变窄，以允许高清晰度记录。 此外，头单元的倾斜布置使得位于分离头单元的基板上的相同位置的记录元件位于相同的主扫描线上，从而防止副扫描方向上的尺寸增大， 实现了整体尺寸的减小。
