| Abstract: | This paper introduces an automatic paper stand of which the scaleplate is driven by the micro machine controlled by closed cycle circuit. The paper stand is of low cost. Its accumulated error is less than 0.8 mm every 30 lines. When finishing typing a line, one can press a key on the computer deyboard to move the scaleplate to the next line. The time of pressing the key has nothing to do with the line space. In addition, one can use the regular keyboard for this stand. |
