Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
89 words
An interface for inputting color image information into a color printer, comprising: a first memory for storing the color image information; a second memory provided separately from said first memory, for storing the color image information; and control means for storing the image information in sequence into said first and second memories, wherein said first and second memories store the same kind of color information, and said control means stores the image information alternatively into said first and said second memories synchronously with printing operation of the color printer.
Claim 2
Dependent Claim
89 words
An interface for inputting color image information into a color printer, comprising: a first memory for storing the color image information; a second memory provided separately from said first memory, for storing the color image information; and control means for storing the image information in sequence into said first and second memories, wherein said first and second memories store the same kind of color information, and said control means stores the image information alternatively into said first and said second memories synchronously with printing operation of the color printer.
Claim 3
Dependent Claim
24 words
An interface according to claim 1, further comprising: an input section for inputting of the color information into said interface responsive to a command.
Claim 4
Dependent Claim
24 words
An interface according to claim 2, wherein said input section is also structured and arranged for inputting of the command, converted into image information.
Claim 5
Dependent Claim
21 words
An interface according to claim 1, further comprising: selecting means for selecting between outputs from said first and said second memories.
Claim 6
Dependent Claim
15 words
An interface according to claim 1, wherein the color printer is an electronic photographic printer.
Claim 7
Dependent Claim
19 words
An interface according to claim 1, wherein said first and second memories have, respectively, memory capacities of a page.
Claim 8
Dependent Claim
