Abstract

PURPOSE:To obtain a character graph storage display device by extending one storage memory section and writing it to a memory where only a character part is extended so as to attain aimed at print-out of the character part. CONSTITUTION:A display data is inputted to an input terminal 9, decoded by a control section 1 and written in a display data storage memory 3 and a character pattern storage memory 4 through a display control section 2. In the write processing and graph drawing, write operation is executed to the display data storage memory 3 and the character pattern storage memory 4 erases a part corresponding to the graph area to be drawn. In character drawing, the character pattern storage memory 4 and the display data storage memory 3 execute writing. Through the operation, when the result is outputted to a binary graphic printer, the content of the character pattern storage memory 4 has only to be read and printed out.

Conventional configurations and their problems Up until now, as a device for outputting the display results of a character/graphics storage/display device to a binary printer, there have been only a few devices used in Japan's teletext broadcasting and captain systems that store brightness information and color information as separate information. By printing out only the luminance information, characters and figures can be outputted satisfactorily by a binary printer. However, North American style teletext and videotex,
Alternatively, in display devices where each memory represents color information, such as the display memory of a personal computer, the only way to print out the contents is to binarize the contents of the memory at a certain appropriate level. In many cases, it is difficult to clearly print out the text portion of the screen, etc.

Structure of the Invention The present invention provides a print-only memory in addition to the figure display memory, stores character information in both memories, and when figure information arrives, the print-only memory stores information corresponding to the figure part. By erasing υ, the latest character information is always stored in the print-only memory, and only the characters on the display screen are printed out.

The control unit 1 operates in response to request data from the keyboard input terminal 11, a request signal to the database is output from the request signal terminal 1o in a required format, and display data is input to the input terminal 9. This data is decoded by the control section 1 and written into the display data storage memory 3 and character pattern storage memory 4 through the display control section 2. At this time, in the writing process to the storage memory, when drawing figures, the display data storage memory 3 is written, and the character pattern storage memory 4 is erased in a portion corresponding to the drawn figure area. In character drawing, both the character pattern storage memory 4 and the display data storage memory 3 are caused to perform writing operations. Through these operations, when outputting these results to a binary graphic printer, it is only necessary to read out the contents of the character pattern storage memory 4 and print them out.
