an ink rank configured to supply ink to the ink jet head,
2. The ink cartridge as claimed in claim 1, wherein the width of the common liquid room on a plane level is narrower substantially consecutively as a point of the width is more remote from the supply opening part.
3. The ink cartridge as claimed in claim 1, wherein the width of the common liquid room on a plane level is narrower substantially gradually as a point of the width is more remote from the supply opening part.
4. The ink cartridge as claimed in claim 1, wherein the common liquid room has a configuration of a single wing on a plane level.
5. The ink cartridge as claimed in claim 1, wherein the common liquid room has a configuration of dual wings on a plane level.
6. The ink cartridge as claimed in claim 5, wherein a wall surface opposite to a liquid room side in the common liquid roam has a substantially arc configuration or a semicircle configuration in a direction of a line.
7. The ink cartridge as claimed in claim 1, wherein the common liquid room is formed by anisotropically etching of a silicon substrate.
8. The ink cartridge as claimed in claim 7, wherein the common liquid room has a wall surface at a liquid room side of the common liquid room, and the wall surface has a plane configuration having an obtuse angle.
9. The ink cartridge as claimed in claim 1, wherein the supply opening part is provided at a surface opposite side to a lid member or a nozzle board forming a wall surface of the liquid room.
10. A picture recording apparatus comprising an ink jet head, the ink jet head comprising:
11. The picture recording apparatus as claimed in claim 10, wherein the width of the common liquid room on a plane level is narrower substantially consecutively as a point of the width is more remote front the supply opening part.
12. The picture recording apparatus as claimed in claim 10, wherein the width of the common liquid room on a plane level is narrower substantially gradually as a point of the width is more remote from the supply opening part.
13. The picture recording apparatus as claimed in claim 10, wherein the common liquid room has a configuration of a single wing on a plane level.
14. The picture recording apparatus as claimed in claim 10, wherein the common liquid room has a configuration of dual wings on a plane level.
15. The picture recording apparatus as claimed in claim 14, wherein a wall surface opposite to a liquid room side in the common liquid room has a substantially arc configuration or a semicircle configuration in a direction of a line.
16. The picture recording apparatus as claimed in claim 10, wherein the common liquid room is formed by anisotropically etching of a silicon substrate.
17. The picture recording apparatus as claimed in claim 16, wherein the common liquid room has a wall surface at a liquid room side of the common liquid room, and the wall surface has a plane configuration having an obtuse angle.
18. The picture recording apparatus as claimed in claim 10, wherein the supply opening part is provided at a surface opposite side to a lid member or a nozzle board forming a wall surface of the liquid room.
This application is a Rule 1.53(b) Continuation of U.S. Ser. No. 10/721,209, filed Nov. 25, 2003, now U.S. Pat. No. 6,913,348, issued Jul. 5, 2005, which in turn is a continuation of U.S. Ser. No. 10/102,464, filed Mar. 20, 2002, now U.S. Pat. No. 6,682,185, issued Jan. 27, 2004, the entire contents of each of which are incorporated by reference herein.
As described above, the wall surface 8 b situated at the side of liquid room 6 in the common liquid room 8 has the configuration of the saw teeth on a plane level. Hence, taking a microscopic view, the width of the common liquid room 8 is not narrower as the point of the width is more remote from the ink supply opening part 19. Rather, the width of the common liquid room 8 may be wider at a point based on a degree of inclination of the saw teeth part of the wall surface 8 a. However, the present invention can be applied to the wall surface 8 a having this discrete wide part. That is, even if the width of the common liquid room 8 may be wider at a point taking a microscopic view, the width of the common liquid room 8 is narrower as the point of the width is more remote from the ink supply opening part 19 as a whole, taking a macro view. In other words, in this specification, “the width of the common liquid room 8 is narrower as the point of the width is more remote from the ink supply opening part 19” includes “the width of the common liquid room 8 may be wider at a point based on the degree of inclination of the saw teeth part of the wall surface 8 a”. Furthermore, a width L2 of a partition wall 21 between the neighboring common liquid rooms 8 has the substantially same length as a width L1 of a partition wall 11 between the neighboring liquid rooms 6. Hence, it is possible to obtain a high strength of the partition wall 21 between the neighboring common liquid rooms 8 and thereby the common liquid room 8 can be kept separate as the neighboring liquid rooms 6 are kept separate.
