Inventor: MINODA TAKATOSHI
IPC: B41J2/16
Filed: 1994-12-14
Abstract: PURPOSE: To make most of added energy contribute to generation of an air bubble by preventing breakdown of an electrode owing to cavitation by a method wherein each of a pair of electrodes provided inside an ink chamber of a head is sandwiched between a substrate composing the ink chamber and an insulating film, and only an end surface is brought into contact with a conductive ink. CONSTITUTION: Each of a pair of electrodes 3 provided inside an ink chamber 1 is sandwiched between a substrate 6 composing the chamber and an insulating film 15, and strong in mechanical strength since only an end surface comes in contact with a conductive ink. Further, since current flows only at an end surface of the electrode, there is non-excessive added energy to the conductive ink, and an air bubble can be efficiently generated. Since most of the added energy contributes to generation of the air bubble, an energy loss content does not remain as heat, the air bubble of a specified size can be always obtained. Further, strongly stabilized durability even against cavitation can be extremely improved.
