PURPOSE:To maintain the space between two data constant even though the letter row printed on the left side in the same line printing the left side data is variable in its length by establshing the prescribed space interval at the point of time when the printing of the data to be printed on the left side is accomplished. CONSTITUTION:The data of the letter, mark or the like to be printed on the left side of the same line are housed in a data buffer 2 from the front address continuously, and a content of a address counter 4 is increased by one by the clock signal CL1 when the AND gate 5 opend, and the position data corresponding to the content of the counter 4 is read out by the data buffer 2. The data to be printed on the right side of the same line is read out from the data buffer by the clock signal LC3 in the same manner, and being sent to a printer 9 through OR circuit 8. The space interval as same as the pre-established distance is established at the point of time when the printing of the data to be printed on the left side, then the right side data is printed. |
