Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
74 words
An ink jet apparatus for discharging a plurality of kinds of ink to a recording medium to thereby effect color recording, having: a plurality of recording means for discharging the ink to thereby effect recording; a carriage carrying said plurality of recording means thereon and scanned along said recording medium; and forwardly and backwardly moving members for moving said plurality of recording means carried on said carriage forwardly and backwardly independently of one another.
Claim 2
Dependent Claim
54 words
An ink jet apparatus according to Claim 1, wherein said forwardly and backwardly moving members select those of said plurality of recording means which are not used, by a recording signal input for the recording of each one line and retract those recording means to a retracted position spaced apart from the recording medium.
Claim 3
Dependent Claim
41 words
An ink jet apparatus according to Claim 1, wherein said carriage retracts all of said recording means by said forwardly and backwardly moving members and is returned to a recording start position each time the recording of one line is terminated.
Claim 4
Dependent Claim
30 words
An ink jet apparatus according to Claim 1, wherein each of said plurality of recording means is provided with a cap member for covering the ink discharge port surface thereof.
Claim 5
Dependent Claim
30 words
An ink jet apparatus according to Claim 1, wherein each of said recording means is provided with an electro-thermal conversion element for generating heat energy utilized to discharge the ink.
Claim 6
Dependent Claim
98 words
An ink jet apparatus for discharging a plurality of kinds of ink to a recording medium to thereby effect color recording, having: a plurality of recording means for discharging the ink to thereby effect recording; a cap member for individually covering the ink discharge port surface of each of said plurality of recording means; and drive control means for selecting those of said recording means which are not used, by a recording signal input for the recording of each one line, and driving and controlling said cap member so as to cover each of said selected recording means.
Claim 7
Dependent Claim
32 words
An ink jet apparatus according to Claim 6, further having forwardly and backwardly moving members for moving said recording means forwardly and backwardly relative to said recording medium independently of one another.
Claim 8
Dependent Claim
52 words
An ink jet apparatus according to Claim 7, wherein said forwardly and backwardly moving members select those of said recording means which are not used, by a recording signal input for the recording of each one line, and retract those recording means to a retracted position spaced apart from the recording medium.
Claim 9
Dependent Claim
40 words
An ink jet apparatus according to Claim 7, wherein all of said recording means are retracted by said forwardly and backwardly moving members and are returned to a recording start position each time the recording of one line is terminated.
Claim 10
Dependent Claim
30 words
An ink jet apparatus according to Claim 6, wherein each of said recording means is provided with an electro-thermal conversion element for generating heat energy utilized to discharge the ink.
