Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 140 words
A data processing apparatus for controlling a printer unit, the printing unit including scanning means for scanning a photosensitive body with modulated light, comprising: code data input means for entering code data; process means for processing the code data entered from said code data input means to generate dot image data; sending means for sending the generated dot image data to the printer unit in order to generate modulated light for the scanning means; signalling means for outputting a signal for instructing a scanning speed of the modulated light, wherein said sending means sends the generated dot image data at a sending speed determined in accordance with size data of a printing medium in the printer unit, and wherein said signalling means outputs the signal for instructing a scanning speed in accordance with the size data of the printing medium.
Claim 2
Dependent Claim 140 words
A data processing apparatus for controlling a printer unit, the printing unit including scanning means for scanning a photosensitive body with modulated light, comprising: code data input means for entering code data; process means for processing the code data entered from said code data input means to generate dot image data; sending means for sending the generated dot image data to the printer unit in order to generate modulated light for the scanning means; signalling means for outputting a signal for instructing a scanning speed of the modulated light, wherein said sending means sends the generated dot image data at a sending speed determined in accordance with size data of a printing medium in the printer unit, and wherein said signalling means outputs the signal for instructing a scanning speed in accordance with the size data of the printing medium.
Claim 3
Dependent Claim 93 words
An apparatus according to claim 1, wherein said code data input means is capable of entering designation data for designating an area on which the image data generated from the code data is to be printed, wherein said sending means sends the generated dot image data at a sending speed determined in accordance with the size data of the printing medium and the designation data, and wherein said signalling means outputs the signal for instructing a scanning speed determined in accordance with the size data of the printing medium and the designation data.
Claim 4
Dependent Claim 17 words
An apparatus according to claim 1, wherein said printing unit is comprised by a laser beam printer.
Claim 5
Dependent Claim 43 words
An apparatus according to claim 3, wherein said scanning means includes a conveyance motor for conveying the printing medium, and wherein said scanning means changes a rotating speed of said conveyance motor on the basis of the signal outputted from said signalling means.
Claim 6
Dependent Claim 40 words
An apparatus according to claim 3, wherein said scanning means includes a rotatable polygonal mirror and wherein said scanning means changes a rotating speed of said rotatable polygon mirror on the basis of the signal outputted from said signalling means.
Claim 7
Dependent Claim 95 words
An apparatus according to claim 1, wherein said apparatus is comprised by a facsimile apparatus and wherein said code data input means enters size data of an image to be printed in accordance with the code data, wherein said sending means sends the generated dot image data at a sending speed determined in accordance with the size data of the printing medium and the entered size data, and wherein said signalling means outputs the signal for instructing a scanning speed in accordance with the size data of the printing medium and the entered size data.
Claim 8
Dependent Claim 86 words
An apparatus according to claim 1, wherein said code data input means enters size designating data for designating a size of the printing medium from host computer means, wherein said sending means sends the generated dot image data at a sending speed determined in accordance with the size data of the printing medium and the size designating data, and wherein said signalling means outputs the signal for instructing a scanning speed in accordance with the size data of the printing medium and the size designating data.
Claim 9
Dependent Claim 47 words
An apparatus according to claim 7, further comprising comparison means for comparing the size data of the printing medium to the size designating data, and wherein said signalling means outputs the signal for instructing a scanning speed in accordance with a comparison result by said comparison means.
