・スキャン型表示装置。In a raster scan type display device in which a character code and graphic data are given as display data from a host computer, a first display control means stores the character code and converts it into a video signal; a second display control means for converting the video signal into a video signal; a video signal addition means for adding the two video signals; a display means for displaying the video signal added by the video signal addition means; and a light pen signal. 1st above
and a light pen signal generating means for supplying the light pen signal to the display control means and the second display control means, and the first display control means is configured to generate a light pen signal when the light pen signal is generated. It is checked whether a character code exists in the generated address or not, and if a character code exists, the character code or a group of character codes including the character code is sent to the host computer, and if the character code does not exist, the character code is sent to the host computer. The second display control means is configured to send a signal indicating the content to the host computer, and the second display control means has at least address storage means readable from the host computer, and when the light pen signal is generated, A raster scan type display device, characterized in that the address at which the i-light pen signal is generated is stored in the address storage means.
