Abstract
A fluid ejection device ejecting a fluid, the fluid ejection device includes: a fluid ejection unit; a fluid container; a delivery needle; and a guard cover. The fluid ejection unit ejects a fluid onto an ejection target. The fluid container includes a container portion and a withdrawal portion. The container portion contains a fluid for ejection, and the withdrawal portion allows withdrawal of the fluid contained in the container portion. The delivery needle sticks through the withdrawal portion to provide a flow passage which communicates with the fluid ejection unit. The guard cover projects over the delivery needle to prevent the withdrawal portion from approaching the delivery needle from a direction intersecting a center axis of the delivery needle.
Claims4
A fluid ejection device ejecting a fluid,
- the fluid ejection device comprising:
- a fluid ejection unit that ejects a fluid onto an ejection target;
- a fluid container that includes a container portion and a withdrawal portion, wherein the container portion contains a fluid for ejection, and the withdrawal portion allows withdrawal of the fluid contained in the container portion;
- a delivery needle that sticks through the withdrawal portion to provide a flow passage which communicates with the fluid ejection unit;
- and
- a guard cover that projects over the delivery needle to prevent the withdrawal portion from approaching the delivery needle from a direction intersecting a center axis of the delivery needle;
- wherein the guard cover includes an opening portion that opens approximately along the center axis of the delivery needle in width narrower than the withdrawal portion.
A method of manufacturing a fluid ejection device including a fluid ejection unit that ejects a fluid onto an ejection target, a delivery needle that provides a flow passage which communicates with the fluid ejection unit, and a guard cover that projects over the delivery needle,
- the method comprising:
- providing a fluid container that includes a container portion and a withdrawal portion, wherein the container portion contains a fluid for ejection, and the withdrawal portion allows withdrawal of the fluid contained in the container portion;
- providing the guard cover with an opening portion that opens approximately along the center axis of the delivery needle in width narrower than the withdrawal portion;
- and
- sliding the fluid container from a direction approximately aligned with a center axis of the delivery needle, toward a locking position where the delivery needle sticks through the withdrawal portion away from the guard cover including the opening portion.
