Abstract
A liquid ejecting head includes: a channel member having channel groups, and actuators. Each of the channel groups has: nozzles, a supply channel, a return channel, and a connecting channel connecting one end in a first direction of the supply channel and one end in the first direction of the return channel. The channel member has a supply port communicating with the other end in the first direction of the supply channel, and a discharge port communicating with the other end in the first direction of the return channel. In two channel groups adjacent in a third direction, a set of the supply and discharge ports communicating with one of the two channel groups and a set of the supply and discharge ports communicating with the other of the two channel groups are arranged to be opposite to each other in the first direction.
Claims22
A liquid ejecting head, comprising:
- a channel member having a plurality of channel groups;
- and
- a plurality of actuators arranged on the channel member,
- wherein each of the channel groups has:
- a plurality of nozzles aligned along a first direction;
- a supply channel extending in the first direction and communicating with the nozzles;
- a return channel extending in the first direction, communicating with the nozzles, and arranged side by side with the supply channel in a second direction crossing the first direction;
- and
- a connecting channel connecting one end in the first direction of the supply channel and one end in the first direction of the return channel,
- the channel groups are aligned in a third direction crossing the first direction,
- each of the actuators is configured to apply energy to liquid in the channel member to cause the liquid to be ejected from one of the nozzles, the actuators being arranged along the first direction to correspond to the nozzles,
- the channel member further has a supply port communicating with the other end in the first direction of the supply channel, and a discharge port communicating with the other end in the first direction of the return channel, and
- in two channel groups, which are included in the channel groups and which are adjacent in the third direction, a set of the supply port and the discharge port communicating with one of the two channel groups and a set of the supply port and the discharge port communicating with the other of the two channel groups are arranged to be opposite to each other in the first direction.
A liquid ejecting head, comprising:
- a channel member having a plurality of channel groups;
- and
- a plurality of actuators arranged on the channel member,
- wherein each of the channel groups has:
- a plurality of individual channels aligned along a first direction;
- a supply channel extending in the first direction and communicating with the individual channels;
- and
- a return channel extending in the first direction, communicating with the individual channels, and arranged side by side with the supply channel in a second direction crossing the first direction,
- the channel groups are aligned in a third direction crossing the first direction,
- the individual channels have nozzles, first communicating channels having one ends communicating with the supply channel and the other ends communicating with the nozzles, and second communicating channels having one ends communicating with the nozzles and the other ends communicating with the return channel,
- each of the actuators is configured to apply energy to liquid in the channel member to cause the liquid to be ejected from one of the nozzles, the actuators being arranged along the first direction to correspond to the nozzles,
- the channel member further has a supply port communicating with one end in the first direction of the supply channel, and a discharge port communicating with one end in the first direction of the return channel, and
- in two channel groups, which are included in the channel groups and which are adjacent in the third direction, a set of the supply port and the discharge port communicating with one of the two channel groups and a set of the supply port and the discharge port communicating with the other of the two channel groups are arranged to be opposite to each other in the first direction.
