Abstract

PURPOSE: To make it possible to increase the number of input items without increment of the number of input switches, by giving a multiple structure to item input switches.
CONSTITUTION: A switches and B switches are stored in coaxial switches 20 respectively. Now, when contacts A0 and B0 of switches 20 are closed, B switch closing is input through signal line (l). Meanwhile, signals 0, 0 and 1 are generated at matrix switches AWC terminals, and 0101 is applied to the input of agreement detecting circuit 25 through signal lines (x) and (y), and gate circuit 26 becomes operatable. Meanwhile, counters 21 and 22 count pulses generated from oscillator 24; and when signal 0 appears on signal lines a0 and b0 and signal 1 appears on signal lines a1 and b1, agreement between them and signals on signal lines (x) and (y) is detected in circuit 25, and circuit 25 generates a signal to output (e). By this signal, circuit 26 issues a signal, and gate circuit 23 is closed, and counters 21 and 22 stop counting. Information of counters 21 and 22 and information of signal line (l) are sent to CPU30 to obtain coding position information of switch group 20.
