Abstract
Abstract An ink jet recording apparatus performs the recording, using a recording head for discharging the ink onto the recording medium to effect the recording, while moving said recording head in a main scan direction. The recording head has a plurality of discharge orifice groups in the main scan direction, each of which has a plurality of discharge orifices for discharging the inks of different colors provided in a direction different from the main scan direction. A predetermined image data is divided into thinned image data, which is in complementary relation to each other, each of the thinned image data being supplied to a different discharge orifice group, so that predetermined image data can be recorded using different discharge orifice groups. The occurence of deviation and unevenness of the printed image can be prevented.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
81 words
An ink jet recording apparatus which performs the recording, using a recording head for discharging the ink onto the recording medium to effect the recording, while moving said recording head in a main scan direction, characterized in that said recording head has a plurality of discharge orifice groups in the main scan direction, each of which has a plurality of discharge orifices for discharging the inks of different colors which are provided in a direction different from the main scan direction.
Claim 2
Dependent Claim
58 words
An ink jet recording apparatus according to claim 1, characterized by further comprising image data supply means for dividing a predetermined image data into pieces of thinned image data in complementary relation to each other and supplying said pieces of thinned image data to respective different discharge orifice groups, which are caused to record said predetermined image data.
Claim 3
Dependent Claim
44 words
An ink jet recording head according to claim 1, wherein said recording head is an ink jet recording head, which discharges the ink by the use of thermal energy, and has electricity-heat converters for generating the heat energy to be applied to the ink.
Claim 4
Dependent Claim
43 words
An ink jet recording apparatus according to claim 3, wherein said recording head causes a state change in the ink due to the heat energy applied by said heat energy converters, and discharges the ink through discharge orifices based on said state change.
Claim 5
Dependent Claim
23 words
An image forming apparatus according to any preceding claim and including either means for receiving image information, or means for transmitting image information.
Claim 6
Dependent Claim
20 words
An image forming apparatus according to any one of the preceding claims, characterised by further comprising original image reading means.
Claim 7
Dependent Claim
16 words
An image forming apparatus as claimed in any preceding claim, and including recording signal input means.
Claim 8
Dependent Claim
19 words
An image forming apparatus according to claim 7, characterised in that said recording signal input means is a keyboard.
Claim 9
Dependent Claim
19 words
An information processing apparatus comprising ink jet recording apparatus as claimed in any preceding claim and including computation means.
Claim 10
Dependent Claim
21 words
An ink jet recording head as claimed in any one of the preceding claims in combination with ink jet recording apparatus.
Claim 11
Dependent Claim
130 words
An ink jet recording method comprising: providing an ink jet recording head for use with an ink jet recording apparatus which performs the recording while moving said recording head in a main scan direction, said recording head discharging the ink onto the recording medium to effect the recording, characterised in that said recording head has a plurality of discharge orifice groups in the main scan direction, each of which has a plurality of discharge orifices for discharging the inks of different colors provided in a different direction from the main scan direction, when mounted on said ink jet recording apparatus; mounting said ink jet recording head on said ink jet recording apparatus; and performing the recording by discharging the ink onto the recording medium from said ink jet recording head.
