Abstract
A liquid discharge apparatus is provided, including a liquid discharge head including: an upper substrate, a plurality of piezoelectric elements, an intermediate substrate, a lower substrate and a plurality of individual traces arranged on the upper substrate and extending toward the contacts arranged on the one end side in the second direction from the plurality of piezoelectric elements respectively.
Claims19
A liquid discharge apparatus configured to discharge a liquid onto a medium comprising:
- a liquid discharge head including:
- an upper substrate including a plurality of first pressure chambers disposed in a first direction, a plurality of second pressure chambers disposed in the first direction and arranged at positions deviated in a second direction orthogonal to the first direction, and a plurality of contacts arranged on one end side in the second direction;
- a plurality of piezoelectric elements arranged at positions of the upper substrate corresponding to the plurality of first pressure chambers and the plurality of second pressure chambers;
- an intermediate substrate including a first manifold communicated with the first pressure chambers and a second manifold communicated with the second pressure chambers, a length of the intermediate substrate in the second direction being larger than that of the upper substrate;
- a lower substrate including a plurality of first nozzles communicated with the first pressure chambers and a plurality of second nozzles communicated with the second pressure chambers, a length of the lower substrate in the second direction being smaller than that of the intermediate substrate;
- and
- a plurality of individual traces arranged on the upper substrate and extending toward the contacts arranged on the one end side in the second direction from the plurality of piezoelectric elements respectively.
