发明名称 Liquid jet head and liquid jet recording apparatus
摘要 A liquid jet head includes an ejecting portion having a first head chip and a second chip which are laminated with each other, and a circuit board which outputs a drive signal for driving the ejecting portion. A first connection board electrically connects the first head chip to the circuit board, and a second connection board electrically connects the second head chip to the circuit board. A bend portion is provided in the circuit board so that by bending the circuit board at the bend portion, the first electrode terminal portion and the second electrode terminal portion are made to extend in the same direction, and face each other in the lamination direction of the head chips. The circuit board has a connecting terminal that is exposed to the outside through a window in the circuit board when the circuit board is bent at the ending portion.

主权项 1. A liquid jet head comprising: an ejecting portion having a first head chip and a second head chip for jetting liquid, the first head chip and the second head chip being laminated with each other; a circuit board for outputting a drive signal for driving the ejecting portion, the circuit board including an external device connecting terminal portion for electrically connecting the circuit board and an external device to each other, and a window portion for allowing the external device connecting terminal portion to be exposed to the outside; a first connection board electrically connecting the first head chip and the circuit board to each other; and a second connection board electrically connecting the second head chip and the circuit board to each other, wherein a first end of the first connection board and a first end of the second connection board are separately formed on any two lateral sides of the circuit board, and wherein, by bending at least any one of the circuit board, the first connection board and the second connection board at a bend portion provided in at least any one of the circuit board, the first connection board and the second connection board, a second end of the first connection board and a second end of the second connection board are made to extend in the same direction.
