Abstract
PURPOSE: To select as an output a detection signal from a specific probe in set priority order, by a tablet with several probes.
CONSTITUTION: Signal detection lines 8b and 9b of proves 8 and 9 are led to inputs of AND gates 24 and 25 of selector circuit 52. Switches 8a and 9a provided corresponding to above-mentioned probes 8 and 9 are led to inputs of AND gates 16 and 17 of priority selector circuit 51. Through operations of inverter 18, AND gate 19, OR gate 20, and FF21, either probe signal is detected without fail and if both probes come in contact, only a circuit corresponding to probe 8 operates, so that malfunction will never be caused. In this case, priority is given to a prove which comes in contact earier and data is outputted.
