Abstract

PURPOSE:To enable split output of an image not confined within a regular recording area onto a plurality of recording sheets, by splitting every input image not confined within a recording area then converting the co-ordinates of the input image address into a record area address and outputting sequentially to recording sections. CONSTITUTION:Unit data containing image data such as characters and control data are received from a data generating source l, and if said data are not a code of data end, the data are stored in an input buffer 3 so as to bring the corresponding bit memory area of a register RR to '1' based on an address position obtained through calculation of the address position of said data. Then a unit data are read out from the input buffer 3, and if said data are the data end code, image data being stored in an output page buffer 7 are fed to an output device a and printed onto a recording paper; thereafter, a paper number count PNC is incremented and when said count equals to the total bit number of the register RR. image output processing is ended. Consequently, the input image is outputted while being split and when a user combines respective output images, original image can be reproduced.
