| 摘要 | PURPOSE:To obtain a good-operable centering function by using a system in which one operating button for centering is operated to select the centering between the left and right margins and the tabulator. CONSTITUTION:The desired letters are written by means of a motor 9 moving a pen laterally, a motor 8 for line feeding by vertically moving a paper, and a motor 10 for separating or vertically moving a pen. These motors 8-10 are controlled by a controller 11 which reads the output of a centering key and each key provided for a keyboard 2 to put a printer 7 into work. When the centering key is pushed, whether a carriage is on the tabulator is judged, and if the carriage is on the tabulator, the centering mode of tabulator is readied for operation. If the carriage is not on the tabulator, the presence of the carriage on the left margin is discriminated, and the centering mode between left and right side margins is started. The centering process of input letters between the left and right side margins is made and printing is performed. When the carriage is not on the tabulator and even on the left margin, a buzzer sounds to avoid starting into centering mode. | ||||||
