20140285574 | HEAD UNIT AND LIQUID EJECTING APPARATUS - A head unit, in which unit head rows are formed by respectively arraying unit heads in parallel on both sides of a transmission substrate. The head unit includes a first liquid fluid channel that is disposed on a first side of the transmission substrate and a second liquid fluid channel that is disposed on a second side of the transmission substrate. The unit heads are provided with a flexible cable. A first head fluid channel sandwiches the flexible cable and is provided on a side that is opposite a transmission substrate side. A second head fluid channel is provided on the transmission substrate side. The first head fluid channel is in communication with a first liquid fluid channel on a surface side on which the unit heads are disposed. The second head fluid channel straddles the transmission substrate and is in communication with a second liquid fluid channel on a surface side that is opposite the unit heads. | 09-25-2014 |
20140292936 | LIQUID EJECTING HEAD AND LIQUID EJECTING APPARATUS - A flexible cable includes a portion that is covered by a solder resist and an exposed portion that is not covered by the solder resist, in which the exposed portion contains a wiring terminal and at least continues to a position closer to an outside than an opening of a wiring member insertion side of a wiring vacant portion in a state in which the wiring terminal portion is connected to an element terminal of a piezoelectric element side and in which the wiring vacant portion is filled with an electrically insulating filling material in a state of covering a joining portion between the element terminal and the wiring terminal within the wiring vacant portion, and in a state in which a protective substrate, which forms the wiring vacant portion by partitioning, and the exposed portion of the flexible cable are not in contact with one another. | 10-02-2014 |
20150021411 | LIQUID EJECTING HEAD - In a liquid ejecting head that includes a pressure generating element which generates pressure fluctuations in a liquid inside a pressure chamber by applying a voltage to an electrode and a wiring member which has a wiring terminal electrically connected to the electrode, and that ejects the liquid through a nozzle by applying the voltage to the electrode and driving the pressure generating element, the liquid ejecting head includes an electrode terminal that is connected to the electrode and is formed in a series over at least a partial region in a bonding region to which the wiring terminal is bonded. The wiring terminal has multiple terminals which are formed by being spaced apart from one another in the bonding region. | 01-22-2015 |
20150042719 | LIQUID EJECTING HEAD AND LIQUID EJECTING APPARATUS - Provided is a liquid ejecting head that includes a manifold which communicates with a plurality of nozzle openings through which liquid is ejected, a compliance portion which constitutes a part of the manifold and is constituted by a film having flexibility, a fixing plate which is fixed to a surface side of the film, which is a side opposite to the manifold, and has an opening formed in an area which constitutes the compliance portion, and a cap member which is fixed to a surface side of the fixing plate, which is a side opposite to the compliance portion, and covers the opening, in which a protrusion portion which regulates adhering of the film to the cap member is provided, in a state where the protrusion portion is not fixed to the fixing plate, in a space formed in a portion between the compliance portion and the cap member. | 02-12-2015 |
20150108257 | VALVE UNIT AND LIQUID EJECTING APPARATUS - Provided is a valve unit which opens/closes a flow path and includes a unit-main body having a pressure-adjustment chamber formed therein, a film sealing an opening of the pressure-adjustment chamber, a pressure-receiving plate adhered to the film, a valve body connected to the pressure-receiving plate, and a spring urging the valve body to the film. The pressure-adjustment chamber has an inlet and an outlet through which the liquid flows, a wall portion facing the pressure-receiving plate, and a first-concave portion facing the pressure-receiving plate. The inlet is opened/closed by the valve body and is provided in the first-concave portion. A gap between the wall portion and the pressure-receiving plate is smaller than that between the first-concave portion and the pressure-receiving plate. The wall portion makes the first-concave portion extend from the inlet to a side opposite to the outlet side, with respect to the inlet. | 04-23-2015 |
20150174901 | LIQUID EJECTING HEAD, LIQUID EJECTING APPARATUS, AND MANUFACTURING METHOD OF LIQUID EJECTING HEAD - Provided is a liquid ejecting head including a fixing plate which includes a first surface and a second surface on a side opposite to the first surface, a plurality of head units which are fixed to the second surface such that the head units can eject liquid to the first surface side of the fixing plate, and a case member which includes a wall portion that is formed to surround the head units and fixed to the fixing plate and which has a plurality of protrusion portions formed in a part of the wall portion, which is the portion facing the fixing plate. | 06-25-2015 |
20150202875 | LIQUID EJECTING APPARATUS - A wiper member | 07-23-2015 |
20150251430 | LIQUID EJECTING APPARATUS AND CONTROL METHOD THEREOF - A liquid ejecting apparatus includes a liquid ejecting head which includes a manifold; a first flow path and a second flow path which are connected to the manifold; a switching unit which switches a communication state between a liquid storage unit and the respective first and second flow paths; a pressure regulating unit which includes a valve which is open due to negative pressure on the manifold side of the first flow path; and a control unit which controls the switching unit, in which the control unit is capable of performing switching between a first mode in which liquid is supplied to the manifold through the valve and a second mode in which liquid is supplied to the manifold without going through the valve. | 09-10-2015 |
