Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
164 words
An ink-jet cartridge including: an ink-jet head body having injection ports and energy generating elements for generating energy used for injecting an ink, said energy generating elements being arranged in correspondence with said injection ports; and an ink storage portion for storing the ink supplied to said ink-jet head body, said ink storage portion being integrally formed with said ink-jet head body, characterized by that: said ink-jet head body and said ink storage portion include coupling members, respectively, which are coupled to each other upon mounting of said ink-jet head body on said ink storage portion, said ink storage portion includes an absorbing member for absorbing the ink and a supply port for supplying the ink, and said ink-jet head body includes an ink communication pipe inserted into said supply port upon coupling of said coupling members during mounting of said ink-jet head body on said ink storage portion so that a guide port of said ink communication pipe abuts against said absorbing member.
Claim 2
Dependent Claim
164 words
An ink-jet cartridge including: an ink-jet head body having injection ports and energy generating elements for generating energy used for injecting an ink, said energy generating elements being arranged in correspondence with said injection ports; and an ink storage portion for storing the ink supplied to said ink-jet head body, said ink storage portion being integrally formed with said ink-jet head body, characterized by that: said ink-jet head body and said ink storage portion include coupling members, respectively, which are coupled to each other upon mounting of said ink-jet head body on said ink storage portion, said ink storage portion includes an absorbing member for absorbing the ink and a supply port for supplying the ink, and said ink-jet head body includes an ink communication pipe inserted into said supply port upon coupling of said coupling members during mounting of said ink-jet head body on said ink storage portion so that a guide port of said ink communication pipe abuts against said absorbing member.
Claim 3
Dependent Claim
48 words
A cartridge according to claim 1, wherein said coupling members comprise a projection formed on said ink-jet head body and an opening formed in said ink storage portion and engageable with said projection, and a part of said ink storage portion which corresponds to said opening has elasticity.
Claim 4
Dependent Claim
20 words
A cartridge according to claim 1, further comprising a filter formed at said guide port of said ink communication pipe.
Claim 5
Dependent Claim
22 words
A cartridge according to claim 1, wherein said energy generating elements are respectively electricity-heat converters for generating heat energy as the energy.
Claim 6
Dependent Claim
16 words
A cartridge according to claim 1, wherein said absorbing member essentially consists of a porous material.
Claim 7
Dependent Claim
14 words
A cartridge according to claim 1, wherein said absorbing member essentially consists of fibers.
Claim 8
Dependent Claim
19 words
A cartridge according to claim 1, wherein said energy generating elements are electro-mechanical converters consisting of piezoelectric elements, respectively.
Claim 9
Dependent Claim
42 words
A cartridge according to claim 1, wherein a direction for injecting the ink from said injection ports is substantially the same as a direction for injecting the ink to positions in said ink-jet head body where said energy generating elements are arranged.
Claim 10
Dependent Claim
40 words
A cartridge according to claim 1, wherein a direction for injecting the ink from said injection ports is different from a direction for supplying the ink to positions in said ink-jet head body where said energy generating elements are arranged.
Claim 11
Dependent Claim
41 words
A cartridge according to claim 1, wherein the direction for supplying the ink from said injection ports is substantially perpendicular to the direction of supplying the ink to positions in said ink-jet head body where said energy generating elements are arranged.
Claim 12
Dependent Claim
31 words
A cartridge according to claim 1, wherein said ink-jet head body is a full-line type head having said plurality of injection ports in correspondence with a width of a recording medium.
Claim 13
Dependent Claim
18 words
An ink-jet apparatus comprising said ink-jet cartridge of claim 1 and a member for carrying said ink-jet cartridge.
