Abstract
Abstract In a facsimile data processing apparatus, printer code, including a line pitch amount control command and character codes are received from a host computer. The character codes are converted into image data and the image data is converted into transmission code such as modified Huffman code. The line space is directly converted into the transmission code, in the form of white code, without the conversion into image data. The line space varies according to the line pitch amount control command by changing the amount of the white code to be added.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
127 words
A facsimile data processing apparatus connectable to a host computer, comprising: first conversion means for receiving printer control code and character code from the host computer and for converting characters corresponding to the received character code into image data; second conversion means for converting the converted image data into transmission code; memory means for memorizing line space amount; code adding means for adding white code, corresponding to the line space amount, stored in said memory means, following said transmission code converted from the image data of one character line; and detecting means for detecting the conclusion of the conversion from image data for one character line into said transmission code, wherein said code adding means adds said white code based on the detection by said detecting means.
Claim 2
Dependent Claim
127 words
A facsimile data processing apparatus connectable to a host computer, comprising: first conversion means for receiving printer control code and character code from the host computer and for converting characters corresponding to the received character code into image data; second conversion means for converting the converted image data into transmission code; memory means for memorizing line space amount; code adding means for adding white code, corresponding to the line space amount, stored in said memory means, following said transmission code converted from the image data of one character line; and detecting means for detecting the conclusion of the conversion from image data for one character line into said transmission code, wherein said code adding means adds said white code based on the detection by said detecting means.
Claim 3
Dependent Claim
38 words
The facsimile data processing apparatus as claimed in claim 1, further comprising a font pattern memory wherein the pattern dot data is limited to the pattern solely and contains no spacing dot data at upper and lower portions.
Claim 4
Dependent Claim
23 words
The facsimile data processing apparatus as claimed in claim 1, wherein said apparatus includes a central processing unit independent from said host computer.
Claim 5
Dependent Claim
62 words
The facsimile data processing apparatus as claimed in claim 1, wherein said printer control codes include a plurality of line pitch control codes, and wherein said memory means memorize the line space amount corresponding to said plurality of line pitch control codes, whereby the amount of white code added by said code adding means varies based on the line pitch control codes.
Claim 6
Dependent Claim
18 words
The facsimile data processing apparatus as claimed in claim 1, wherein said transmission code is modified Huffman code.
Claim 7
Dependent Claim
40 words
The facsimile data processing apparatus as claimed in claim 1, wherein said memory means memorizes the line space amount as the difference between the raster number of the line pitch and the raster number of one line of image data.
Claim 8
Dependent Claim
62 words
The facsimile data processing apparatus as claimed in claim 1, further comprising imaging vertical position storing means for storing the uppermost raster of the one line image data to be subjected to the conversion into transmission code, and coding vertical position storing means for storing a vertical raster position to be subjected to the conversion into transmission code at the next time.
Claim 9
Dependent Claim
41 words
The facsimile data processing apparatus as claimed in claim 7, wherein said code adding means adds said white code until reaching the vertical raster position indicated by said imaging vertical position storing means following the converted code for one character line.
Claim 10
Dependent Claim
119 words
A facsimile data processing apparatus usable with a host computer, comprising: a central processing unit; a first conversion means for converting character data from the host computer into image data; a second conversion means for converting the image data into transmission code; a line space creation means for generating spacing between lines directly as transmission code, wherein said central processing unit controls said first and second conversion means and said line space creation means; and detecting means for detecting the conclusion of the conversion of one line of image data into transmission code, wherein said line space creation means adds the transmission code corresponding to a space between lines at the end of each line of converted transmission code.
Claim 11
Dependent Claim
119 words
A facsimile data processing apparatus usable with a host computer, comprising: a central processing unit; a first conversion means for converting character data from the host computer into image data; a second conversion means for converting the image data into transmission code; a line space creation means for generating spacing between lines directly as transmission code, wherein said central processing unit controls said first and second conversion means and said line space creation means; and detecting means for detecting the conclusion of the conversion of one line of image data into transmission code, wherein said line space creation means adds the transmission code corresponding to a space between lines at the end of each line of converted transmission code.
Claim 12
Dependent Claim
42 words
The facsimile data processing apparatus as claimed in claim 9, wherein a control code may be entered from the host computer to change a size of the spacing between lines that is converted into transmission code by said line space creation means.
