The present invention relates to a character image editing system that edits on a display screen a composite manuscript image in which line drawings read by etc. are composited to generate a draft manuscript or a printing plate.

[Conventional technology]

In recent years, in order to cope with the increasing demand for printing,
CPU, storage device, display, keyboard,
A character image editing system that includes a printer and the like and can easily edit and generate printed manuscripts has been developed. This system can generate print manuscripts from document files created with Japanese word processors, etc., and can easily create composite manuscripts of documents and line drawings (binary images) on the display screen, which could hardly be processed with conventional word processors. can be edited.

[Problem that the invention seeks to solve]

However, in such conventional character image editing systems, the word processor is positioned as an auxiliary input means, and a dedicated character input device is prepared separately from the word processor. Since most of these dedicated character input machines are equipped with full-fledged typesetting functions, they have the disadvantage that they cannot be used without knowledge of typesetting. Data can also be input into this character image editing system from a word processor via an information recording medium such as a floppy disk, but in this case, only character code data is input, including enlargement, vertical writing, and underlining. Function code data such as line and bag binding printing is not input. These instruction data for enlargement, vertical writing, underlining, double-page printing, etc. must be input using a dedicated input device, which has the drawback of increasing the time and effort required for re-editing after converting character code data.

The present invention has been made to address the above-mentioned circumstances, and an object of the present invention is to provide a character image editing system that allows editing and printing of high-quality documents similar to printed text with simple operations.
