Abstract

PURPOSE: To decrease the number of wires and remarkably diminish the number of wiring man-hour, by making common the data line bunching which is directly connected to the input contact group and the output indicator group, and making each data line have the bilateral property of input and output.
CONSTITUTION: An output of the address driving circuit 14 makes active only one address line among the address line bunching in accordance with a command by the time division of the computer 1, and in case when said address line is connected to the input contact group 6, a state of the contact connected to said address line appears as a digital signal in the data line bunching 15, and it is loaded into the computer 1 through the data input/output circuit 13. In case one address line which has become active is connected to the output indicator group 7, an indicator of the output indicator group 7 to which said address line is connected is driven by a data of the data line bunching 15 which is output from the data input/output circuit 13.
