Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
108 words
In an image reproducing system wherein a reproduction image is generated by photo-electric scanning of an original and spraying an image generating substance by scanning a recording member with an image generating device, the improvement wherein; said image generating device comprises: at least one liquid pigment supply fluid coupled to a pigment supply nozzle corresponding thereto and facing said recording member, an air emitting port in juxtaposition to said nozzle for spraying pigment onto said recording member, means for supplying said port with a constant volume air flow, and means for varying the area of the pigment supply nozzle opening in accordance with the density of the original.
Claim 2
Dependent Claim
108 words
In an image reproducing system wherein a reproduction image is generated by photo-electric scanning of an original and spraying an image generating substance by scanning a recording member with an image generating device, the improvement wherein; said image generating device comprises: at least one liquid pigment supply fluid coupled to a pigment supply nozzle corresponding thereto and facing said recording member, an air emitting port in juxtaposition to said nozzle for spraying pigment onto said recording member, means for supplying said port with a constant volume air flow, and means for varying the area of the pigment supply nozzle opening in accordance with the density of the original.
Claim 3
Dependent Claim
47 words
The image reproducing device of claim 1, wherein a regulator for varying the area of the nozzle opening includes a cover disposed in the front of the nozzle opening and coupled to a drive rod which is laterally moved in response to the density of the original.
Claim 4
Dependent Claim
21 words
The image reproducing device of claim 1, wherein the opening of the nozzle has a progressively expanding width of wedge-like configuration.
Claim 5
Dependent Claim
25 words
The image reproducing device of claim 2, wherein the opening of the nozzle is of non-linearly expanding width to form a logarithmically progressively expanding opening.
Claim 6
Dependent Claim
47 words
The image reproducing device of claim 1, wherein a plurality of different color image generating substance spraying nozzles are disposed around said air emitting port and each nozzle has a regulator for varying the area of the corresponding nozzle oPening to achieve multi-color reproduction of the image.
