Abstract
There is provided a liquid discharge head, including: a nozzle member formed having nozzle rows extending in a first direction, the nozzle rows being arranged in a second direction; driving elements; a first channel member disposed at one side of the nozzle member in a third direction; a second channel member disposed at the one side of the first channel member in the third direction; and a third channel member disposed at the one side of the second channel member in the third direction.
Claims14
A liquid discharge head, comprising:
- a nozzle member including a plurality of nozzles that form parts of a plurality of individual channels, the nozzles forming a plurality of nozzle rows that extend in a first direction, the nozzle rows being arranged in a second direction intersecting with the first direction;
- a plurality of driving elements corresponding to the respective individual channels, each of the driving elements configured to apply discharge energy to a liquid in a corresponding one of the individual channels;
- a first channel member disposed at one side of the nozzle member in a third direction orthogonal to the first direction and the second direction,
- the first channel member including:
- a plurality of first supply channels corresponding to the respective nozzle rows, the first supply channels extending in the first direction, each of the first supply channels communicating with a corresponding one of the individual channels;
- and
- a plurality of first return channels corresponding to the respective nozzle rows, the first return channels extending in the first direction, each of the first return channels communicating with a corresponding one of the individual channels;
- a second channel member disposed at the one side of the first channel member in the third direction,
- the second channel member including:
- a plurality of second supply channels corresponding to the respective first supply channels, each of the second supply channels communicating with a corresponding one of the first supply channels;
- and
- a plurality of second return channels corresponding to the respective first return channels, each of the second return channels communicating with a corresponding one of the first return channels;
- a third channel member disposed at the one side of the second channel member in the third direction,
- the third channel member including:
- a third supply channel provided in common to the second supply channels and communicating with the second supply channels;
- and
- a third return channel provided in common to the second return channels and communicating with the second return channels,
- wherein the second channel member further includes a first bypass channel connecting the third supply channel and the third return channel, and
- wherein the third channel member further includes a second bypass channel connecting the third supply channel and the third return channel.
