摘要： To prevent corrosion and disconnection of an anisotropic conductor film due to ink and ink vapor and to eliminate discharge defects in an ink jet print head having a structure in which a head chip and a circuit substrate for driving the head chip are interconnected by an FPC substrate through the anisotropic conductor film, an outer periphery of the interconnecting portion is molded throughout a full range by a sealant so as to cut off the interconnecting portion from external air. The sealant is of an epoxy type, a silicone type or an acrylic type. An epoxy sealant having low viscosity (50 pa·s or below) and high hardness (85 or more: JISA standard) is used for a first layer sealant of the interconnecting portion and a silicone sealant having high viscosity (70 pa·s or more) is used for a second layer sealant to achieve a two-layered molding structure.

摘要： An air damper for use with an ink jet head has a main body having an ink reservoir portion, and a film sealed to the main body and covering the ink reservoir portion to define therewith an ink reservoir. A reinforcement plate is attached to the main body and overlies the film to prevent rupture of the film due to expansion thereof when the ink jet head is pressure-filled with ink. The reinforcement plate has a recessed portion opposed to and facing the film to permit limited expansion of the film caused by pressure fluctuations of ink in the ink reservoir.
