摘要： There are provided an ejection actuator that ejects ink from a nozzle, and a driver chip that supplies a signal for driving the ejection actuator. In a first location, the driver chip is sandwiched between a flat plate member and an elastic member. The elastic member biases the driver chip to the flat plate member. The elastic member is supported by the support member. A restricting portion is provided on at least either one of the support member and the flat plate member. When the support member and the flat plate member get close to each other in a second location different from the first location, the restricting portion restricts movement of at least either one of the support member and the flat plate member so as to prevent the driver chip and the support member in the first location from getting closer to each other beyond a minimum distance. Here, the minimum distance means a distance between the support member and the flat plate member in the first location at the time when the elastic member is compressed to the maximum limit.

摘要： An ink-jet head includes a flexible print cable (FPC) supplying a driving signal to an actuator unit. The actuator unit has a piezoelectric member, an inner electrode, individual electrodes formed on a surface of the piezoelectric member, a first surface terminal and second surface terminals. A partial area of the FPC confronts the surface of the piezoelectric member and an adjacent area continuous to the partial area extends in a direction away from the surface of the piezoelectric member. A distance between an end of the surface of the piezoelectric member closest to the adjacent area and the first surface terminal is equal to or greater than a distance between the end surface of the piezoelectric member and the second surface terminal disposed closest thereto. The FPC is adhered proximate the end of the piezoelectric member via a thermosetting adhesive.

摘要： The first passage component and the second passage component are fixed with each other as the male screw part is screw-engaged with the female screw hole while the cylinder part is inserted into the through-hole. The second passage component has a convex contacting the head and a spaced surface spaced apart from the head in the axial direction, both in a first annular confronting area confronting the head of the stepped screw, at a surrounding of the through-hole of the third surface. The axial length of the cylinder part is same as the length of a line segment extending to the second surface from the leading end of the convex in the axial direction, while the axial length of the cylinder part is smaller than the length of the line segment until the male screw part is screw-engaged with the female screw hole.

摘要： An ink-jet head of the present invention includes a discharge valve that includes a valve chamber and an opening/closing mechanism. The valve chamber has an ink supply port through which ink is supplied from outside, an outside discharge port through which ink is discharged to outside, and a reservoir discharge port through which ink is discharged to an ink reservoir. The opening/closing mechanism is able to selectively take either one of a state where a passage is formed between the ink supply port and the outside discharge port while access between the ink supply port and the reservoir discharge port is blocked and a state where a passage is formed between the ink supply port and the reservoir discharge port while access between the ink supply port and the outside discharge port is blocked.
