LIQUID EJECTING HEAD UNIT AND LIQUID EJECTING APPARATUS

摘要

A liquid ejecting head unit includes a first flow path member with a first flow path and a second flow path member with a second flow path which is stacked on the first flow path member. A seal member connects the first and second flow paths and has a first seal part and a second seal part. The first flow path member applies a force to the first seal part in a stacking direction of the first and second flow path members. The second flow path member applies a force to the second seal part in a direction from the center of the second flow path to the outside and normal to the stacking direction. A retaining part controls expansion of the seal member in the normal direction with a control part. A drive element ejects liquid supplied through the first and the second flow paths through nozzles.

主权项

1. A liquid ejecting head unit comprising:
a first flow path member having a first flow path; a second flow path member having a second flow path, the second flow path member being stacked on the first flow path member; a seal member that connects the first flow path to the second flow path, the seal member having a first seal part and a second seal part, the first flow path member applying a force to the first seal part in a stacking direction in which the second flow path member is stacked on the first path member, the second flow path member applying a force to the second seal part in a direction from a center of the second flow path to an outside thereof, the direction being perpendicular to the stacking direction; a bar against expansion of the seal member in the perpendicular direction by a control part thereof; and a drive element configured to eject liquid through a nozzle, the liquid supplied through both the first flow path and the second flow path.
