摘要：A character board carrying a number of characters is placed in face-to- facerelationship with a light source matrix comprising light sources of the same number asthat of the characters so that one character may be illuminated by one light source. Eachcharacter is divided into a predetermined number of sections or dots. A photodetectormatrix comprising photodetectors of the same number as that of the sections into whichthe character is divided is provided in connection with the character board. Optical fibersof the same number as that of the sections are provided for each character to transmitthe light passing through the character to the photodetectors of the photodetectormatrix. The corresponding sections of the respective characters are connected with thesame photodetector by means of optical fibers so that every photodetector may receivesignals from the sections in the same position of the different characters. The

photodetectors are connected with a scanning line selecting circuit by way of amplifiers.In accordance with the output of the character generator as constructed above,characters are displayed in a display such as a cathode ray tube.
