Abstract
PURPOSE: To simplify operation of a driver by recovering over again automatically to a certain indication after changing over to the other indication at a certain time when a driver turns on an automatic indicating switch at a certain point.
CONSTITUTION: When a driver turns on the automatic indicating switch A at a certain time, one shot multi D3 is triggered at down condition of pulse generating according to the actuation of momentum of switch A to generate a square pulse. In this case, the logic level of power of OR gate D2 becomes "H". The logic level of power of NAND gate D1 becomes "L". Accordingly a data select signal is not selected. The signal 2 is selected owing to the output of D3 being "H". A multiplexer not showing in the diagram, for example, selects the travelling error distance, which is indicated for a certain time. The power Q3 of one shot multi D3 becomes from "H" to "L" after elapsing a certain time, with down condition of which one shot multi D4 is triggered, selecting the data select signal to change automatically the indication.
