Passage member, liquid discharge head using same, and recording device
A passage member of the present disclosure includes a plurality of plates including openings forming a passage through which a liquid flows and stacked through an adhesive. In at least one plate, a plurality of adhesive spill holes are arranged at substantially the same distances from the opening, so as to surround the opening.
1. A passage member comprising:
a plurality of plates that are stacked using an adhesive and configured with openings forming a passage through which a liquid flows, wherein a first plate of the plurality of plates is further configured with a plurality of first openings and a plurality of independent first adhesive spill holes arranged at substantially a same distance from one of the plurality of first openings and surround the one of the plurality of first openings.
2. The passage member according to claim 1 , wherein each of opening areas of the plurality of first adhesive spill holes is smaller than an opening area of the one of the plurality of first openings.
3. The passage member according to claim 1 , wherein the first adhesive spill holes arranged at the surroundings of the one of the plurality of first openings are arranged rotationally symmetrically.
4. The passage member according to claim 1 , further comprising:
a second plate of the plurality of plates which is stacked on the first plate and comprises a plurality of second openings as the openings and a plurality of independent second adhesive spill holes arranged at substantially the same distance from one of the plurality of second openings and surround the one of the plurality of second openings, wherein the one of the plurality of first openings and the one of the plurality of second openings are connected,
the second adhesive spill holes are arranged in a surface of the second plate at a side of the first plate, and
when viewed on a plane, the second adhesive spill holes are not arranged at positions with respect to the one of the plurality of first openings opposite to the first adhesive spill holes.
5. The passage member according to claim 1 , further comprising:
a second plate of the plurality of plates which is stacked on the first plate and comprises a plurality of second openings as the openings and a plurality of independent second adhesive spill holes arranged at substantially the same distance from one of the plurality of second openings and surround the one of the plurality of second openings, wherein,
the one of the plurality of first openings and the one of the plurality of second openings are connected,
the first adhesive spill holes are arranged in rotational symmetry of order “n” (“n” is an odd number of 3 or more), and
when viewed on a plane, the second adhesive spill holes are arranged at positions the first adhesive spill holes.
6. The passage member according to claim 1 , wherein:
the plurality of first adhesive spill holes arranged at substantially a first distance from the one of the plurality of first openings, and
the first plate further comprises a plurality of independent second adhesive spill holes arranged at substantially a second distance from the one of the plurality of first openings and surround the one of the plurality of first openings, the second distance being longer than the first distance.
7. The passage member according to claim 6 , wherein, when viewed from the opening, the second adhesive spill holes are arranged at positions that overlap clearances between two of the first adhesive spill holes arranged adjacent to each other.
8. The passage member according to claim 6 , wherein, when viewed from the one of the plurality of first openings, size of the second adhesive spill holes are larger than the size of the first adhesive spill holes.
9. The passage member according to claim 1 , wherein:
apertures of said first adhesive spill holes are circular shaped.
10. A liquid discharge head comprising:
the passage member according to claim 1 , and pressurizing parts pressurizing the liquid in the passage.
11. A recording device comprising:
the liquid discharge head according to claim 10 ,
a conveying part conveying a recording medium with respect to the liquid discharge head, and
a control part controlling the liquid discharge head.
12. A passage member comprising:
a plurality of plates configured with openings forming a passage through which a liquid flows and stacked through an adhesive, wherein
a first plate of the plurality of plates is further configured with a plurality of first openings as the openings and a plurality of independent first adhesive spill holes arranged on a circumference centered on one of the plurality of first openings and surround the one of the plurality of first openings.
13. A liquid discharge head comprising:
the passage member according to claim 12 , and pressurizing parts pressurizing the liquid in the passage.
14. A recording device comprising:
the liquid discharge head according to claim 13 ,
a conveying part conveying a recording medium with respect to the liquid discharge head, and
a control part controlling the liquid discharge head.
