Abstract:
A data processing device for simultaneously reading out plural lines of image, comprising:a data inputting mechanism configured to generate line by line in order dot-matrix-state data in synchronism with an input clock;at least m memories having a memorizing capacity capable of memorizing one or more lines of said dot-matrix-state data generated by said data inputting medium, wherein m is an integer equal to or greater than n.times.2, and n is another integer equal to or greater than two;a memory writing-in mechanism configured to write the dot-matrix-state data from said data inputting mechanism line by line in order into said at least m memories in synchronism with the input clock during a write-in period;a memory reading-out control mechanism configured to write in n lines of data generated by said data inputting mechanism line by line in order into n memories among said at least m memories in synchronism with the input clock, to simultaneously read out (m-n)-lines of data from memories other than said n memories in synchronism with a printing clock during said write-in period, and to change the memory for reading out the data stored in said at least m memories and repeating the operation of reading-out the image data whenever the n-lines of data are written into said n memories; andn image processing mechanisms configured to output printing image data on respective lines on the basis of plural-lines of image data read out from said n memories.
