Claims

[Scope of utility model registration request]

A device in which three primary color signals of R, G, and B, which are supplied as video signals to a color CRT using a three primary color demodulation excitation method, and horizontal and vertical synchronization signals are inputted from a personal computer, and the three primary color signals are inputted from a personal computer. Select one of the three AND gate circuits that individually gate each of the three AND gate circuits, and select any color obtained by combining the three primary colors.The opening and closing of the gates of the three AND gate circuits are individually controlled. R, G, B select switch, an OR gate circuit that takes the logical sum of each signal output from the three AND gate circuits, and output from the OR gate circuit in synchronization with the horizontal and vertical same signals. The signal has a predetermined number of bits as 1
By using a serial/parallel data converter to convert into parallel data as a unit and accumulating the parallel data output from this serial/parallel data converter, the data can be displayed on one screen or one scanning line of the CRT. a memory circuit that is capable of storing an amount of information; and a memory circuit that is capable of storing an amount of information that is synchronized with the horizontal and vertical synchronization signals in order to sequentially write parallel data output from the serial/parallel data converter into the memory circuit in the predetermined units. an address counter that generates a write command signal that specifies an address to be stored in the memory circuit; a read counter that generates a read command signal that reads out the parallel data stored in the memory circuit in the predetermined unit; a parallel/serial data converter that converts read parallel data into serial pulse data; an oscillator that generates a timing clock pulse signal, and supplies the timing clock pulse signal output from the oscillator as a driving pulse to the read counter and the parallel/serial data converter. , B monochrome printer device using input method.
