Liquid ejecting head, liquid ejecting method, and method for manufacturing liquid ejecting head

摘要

A liquid ejecting head is provided comprising a member provided with a plurality of ejecting outlets which eject liquid; a substrate having a plurality of bubble generating means which generates thermal energy for generating and growing a bubble which ejects the liquid, the bubble generating means opposing the associated liquid ejecting outlet; a plurality of liquid flow paths each of which communicates with the associated ejecting outlet and has a bubble generating region for generating the bubble in the liquid by the thermal energy; a common liquid supply chamber which communicates with the plurality of said liquid flow paths via a liquid supply inlet and which supplies liquid to the plurality of said liquid flow paths via the liquid supply inlet, the liquid supply inlet being a long through-hole formed in the substrate; and a plurality of movable members disposed in the longitudinal direction of the liquid supply inlet so as to cover the liquid supply inlet, each of the movable members having a free end in the associated liquid flow path and being supported above the liquid supply inlet with a minute spacing therebetween. According to this novel liquid ejecting head having the structure described above, improvements of both ejecting power and ejecting frequency can be achieved, and a conventional problem in which liquid flow paths are adversely affected to each other can also be solved. A method for ejecting liquid using the liquid ejecting head described above and a manufacturing method therefor are also disclosed.
