Abstract

PURPOSE:To check the whole sequence drawing by forming the whole sequence drawing while displaying a part of the sequence drawing to which data are being inputted and switching a part to be displayed by a shifting means. CONSTITUTION:Information inputted from an operating part 31 is transmitted to a sequence editing part 32, the decoding function of which converts symbol information into a symbol display code and position information into a timing signal to transfer the symbol display code to a one-line buffer 35. Consequently symbol code data are sequentially stored in prescribed positions in the one-line buffer 35. The symbol display codes corresponding to one line are transmitted to a display controlling part 36 to be converted into a display signal and displayed in simple display part 37. If an advancement key 29 is depressed after forming the sequence drawing for one line, the data in the one-line buffer 35 are transferred to a one-circuit buffer 34. When the sequence drawing for one circuit has been stored, the contents are transferred to a sequence controlling circuit 1.
