PROBLEM TO BE SOLVED: To prevent instability in electrical potential in signal wiring connecting electric parts such as a control circuit.SOLUTION: A game controlling device comprises: game controlling means; and outer section expanding means (181) having a function for generating and outputting extension selection signal of signal input/output means arranged in an expanded I/O space. In the game controlling device, installed is a composite resistor (71) comprising: a plurality of resistance elements; a common terminal (COM) which is connected to one of terminal of the plurality of resistance elements and to which a predetermined voltage is applied from outside; and a plurality of individual terminals connected to the other terminal of each of the plurality of resistance elements. By connecting the individual terminals of the composite resistor with signal wiring for transmitting the extension selection signal from the outer section expanding means to the signal input/output means and applying the predetermined voltage to the individual terminals via the resistance elements, a voltage level within a predetermined range may be transmitted as the extension selection signal. A part of the individual terminals among the plurality of individual terminals of the composite resistor is not connected with the signal wiring and subjected to the same voltage with the common terminal. |
