Abstract
A head unit fixed to a case in a position in which a nozzle forming surface thereof faces a first surface side of a head fixing portion, and a wiring substrate is arranged on a second surface side opposite from the first surface on a portion. A supply flow channel in the case communicate with a common liquid chamber at an end portion of the communicating flow channel in a first direction, and a flexible cable is disposed inside the supply flow channel in the case in the first direction.
Claims6
A liquid ejecting head comprising:
- a holding member, the holding member including:
- a head unit including a nozzle forming surface in which nozzles are formed so as to be arranged horizontally in a first direction;
- a pressure generating unit configured to cause pressure variations in a pressure chamber communicating the nozzles;
- and a common liquid chamber formed along the first direction and to which a liquid common to a plurality of the pressure chambers is introduced, and configured to eject the liquid from the nozzles by driving the pressure generating unit;
- a wiring member electrically connected at an end portion thereof to the pressure generating unit;
- a wiring substrate electrically connected to the other end portion of the wiring member and configured to supply a drive signal to the pressure generating unit via the wiring member;
- a supply flow channel configured to supply the liquid from a liquid supply source to the common liquid chamber, wherein
- the head unit is fixed to the holding member in a position in which the nozzle forming surface thereof faces a first surface side of a head fixing portion, and the wiring substrate is arranged on a second surface side of the head fixing portion opposite from the first surface,
- the supply flow channel communicates with the common liquid chamber at an end of the common liquid chamber in the first direction, and
- the wiring member is disposed inside the supply flow channel in the first direction in the holding member.
