Document Type and Number:
Japanese Patent JP2021011085
Kind Code:
A
Abstract:
To sufficiently ensure a circulation flow rate of a liquid.SOLUTION: A liquid discharge head includes: two supply manifolds 41a and 41b respectively provided on a first individual channel group 50a and a second individual channel group 50b; two feedback manifolds 42a and 42b respectively provided on the first individual channel group 50 and the second individual channel group 50b; and bypass channels 48a and 48b that communicate the two supply manifolds 41a and 41b and the feedback manifolds 42a and 42b. A first pressure P1 of the supply manifold 41a, a second pressure P2 of the supply manifold 41b, a third pressure-P1 of the feedback manifold 42a, and a forth pressure-P2 of the feedback manifold 42b satisfy a relationship of |P1|>|P2|.SELECTED DRAWING: Figure 3
