发明名称 ELECTRONIC SCALE
摘要 PURPOSE:To execute a scale display by basing on the left or the right as a reference, by providing a scale mode storage part, and setting a forward direction scale mode or a backward direction scale mode by a key operation. CONSTITUTION:A scale up to, for instance, 150mm. is printed on a scale part. A scale display part 7 is provided with 150 pieces of scale electrodes in parallel to the scale part by using a liquid crystal display element. A forward direction original point display electrode and a backward direction original point display electrode are provided on the left end and the right end, respectively, and one needle and the other needle display a forward direction scale and a backward direction scale, respectively. A mode is displayed on display symbols 10A, 20B. A numerical value input data held in a key input register 23 is inputed to forward direction and backward direction registers 28, 29 by a pulse driven by a scale display signal Scale. A data selector 31 sends out one of contents of the registers 28, 29 in accordance with contents of a scale mode storage part 32, and an inverting circuit replaces a data in the backward direction at the time of the backward direction.
