Abstract
In a character displaying device having a character pattern memory which is made up of a circulating sequential access memory storing character patterns therein, a character pattern generating system comprises a high speed buffer memory which stores the character codes of one line or any other suitable amount of characters to be displayed and the corresponding character patterns, so that each time one character is delivered as an output from the character pattern memory, the presence of the character code of the particular character is examined for all the character codes of the buffer memory, and the character pattern of the particular character is written into the buffer memory when the character codes are coincident, the writing operations being sequentially executed in the order of the character outputs of the character pattern memory, thereby making it possible to finish all the character patterns in the buffer memory within a period in which the read-out of the character pattern memory circulates.
