Abstract
Abstract A storage control system for a print image data in a print control apparatus includes a unit for generating a print image expressed by a set of a plurality of dots as a digital data having a dot carrying a two-dimensional address corresponding to a bit, an address conversion unit for converting a digital data carrying a two-dimensional address into a digital data carrying a one-dimensional address, and a full-dot memory for storing a digital data carrying a one-dimensional address in a one-dimensional address structure.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
234 words
A print image data storage system comprising: means for generating digital print image data representing a plurality of dots to be printed on a sheet of paper, each of the dots being represented by one bit of the digital print image data and having a two-dimensional address associated therewith, the two-dimensional address including an x-address representing an abscissa of the dot on the sheet of paper and a y-address representing an ordinate of the dot on the sheet of paper; a first register for designating y-addresses of the dots to be printed on the sheet of paper; a second register for designating x-addresses of the dots to be printed on the sheet of paper; a third register for designating information about the sheet of paper; address conversion means responsive to the first register, the second register, and the third register for converting two-dimensional addresses specified by the y-addresses designated by the first register and the x-addresses designated by the second register to one-dimensional addresses based on the y-addresses designated by the first register, the x-addresses designated by the second register, and the information about the sheet of paper designated by the third register; and a one-dimensional full-dot memory receiving the digital print image data from the digital print image data generating means and responsive to the one-dimensional addresses from the address conversion means for storing the digital input image data at the one-dimensional addresses.
Claim 2
Dependent Claim
234 words
A print image data storage system comprising: means for generating digital print image data representing a plurality of dots to be printed on a sheet of paper, each of the dots being represented by one bit of the digital print image data and having a two-dimensional address associated therewith, the two-dimensional address including an x-address representing an abscissa of the dot on the sheet of paper and a y-address representing an ordinate of the dot on the sheet of paper; a first register for designating y-addresses of the dots to be printed on the sheet of paper; a second register for designating x-addresses of the dots to be printed on the sheet of paper; a third register for designating information about the sheet of paper; address conversion means responsive to the first register, the second register, and the third register for converting two-dimensional addresses specified by the y-addresses designated by the first register and the x-addresses designated by the second register to one-dimensional addresses based on the y-addresses designated by the first register, the x-addresses designated by the second register, and the information about the sheet of paper designated by the third register; and a one-dimensional full-dot memory receiving the digital print image data from the digital print image data generating means and responsive to the one-dimensional addresses from the address conversion means for storing the digital input image data at the one-dimensional addresses.
Claim 3
Dependent Claim
27 words
A system according to claim 1, wherein the information about the sheet of paper designated by the third register includes a size of the sheet of paper.
Claim 4
Dependent Claim
28 words
A system according to claim 2, wherein the information about the sheet of paper designated by the third register further includes an orientation of the sheet of paper.
Claim 5
Dependent Claim
100 words
A system according to claim 1, wherein the address conversion means includes a multiply memory for storing a table of results of multiplying the y-addresses designated by the first register by widths of a plurality of sheets of papers having different sizes and orientations, and wherein said multiply memory receives the y-addresses designated by the first register and the information about the sheet of paper designated by the third register and outputs portions of the one-dimensional addresses in response to the y-addresses designated by the first register and the information about the sheet of paper designated by the third register.
Claim 6
Dependent Claim
41 words
A system according to claim 4, wherein the address conversion means further includes an adder for adding the x-addresses designated by the second register to the portions of the one-dimensional addresses output by the multiply memory to produce the one-dimensional addresses.
