ABSTRACT:
In an indication device comprising a plurality of indicators of the present invention, each indicator has an indicator control section inputting each signal except for data signals, and a logic section inputting data signals. The logic section receives an output of a logic section in an adjacent indicator, adds and/or subtracts a pre-determined number to and/or from a received signal, then outputs a result to a logic section in another indicator. More, the logic section outputs a signal corresponding to a location of the indicator to an indicator control section.
