Claim Text:
1. A light source control device configured to control a plurality of light sources provided in a game machine, an anode of each of the plurality of light sources being connected to one of at least one first signal wire, a cathode being connected to one of a plurality of second signal wires, the light sources differing from each other in a set of the connected first signal wire and second signal wire, the light source control device comprising: a plurality of first output pins; a plurality of second output pins; an interface; a storage; a dynamic controller; a period-setting unit; and a gradation controller, wherein each of the plurality of first output pins is provided in corresponding one of the at least one first signal wire, wherein the plurality of first output pins connect to a drive circuit that switches whether power is supplied to the first signal wire, wherein the plurality of second output pins connect with one of the plurality of second signal wires; wherein the interface comprises gradation data for each of the plurality of light sources, wherein the gradation data specifies an emission amount of one of the plurality of light sources using a plurality of bits, wherein the interface receives a serially-transmitted control command and an operation mode signal designating an operation mode applied in a plurality of operation modes, wherein the operation modes differ from each other in a combination of the number of first signal wires and the number of second signal wires, wherein the storage stores each piece of gradation data, wherein the dynamic controller decides a first period such that the first signal wires differ from each other in timing of supplying the power according to the number of first signal wires used in the operation mode designated by the operation mode signal, wherein the dynamic controller outputs a signal to each first output pin connected to the drive circuit in the plurality of first output pins, wherein the signal causes each first output pin to supply the power to the first signal wire during the first period, wherein the drive circuit is connected to the first signal wire used in the designated operation mode, wherein the period-setting unit sets a second period to each of the plurality of second signal wires used in the designated operation mode, the second period during which the light source is able to be energized according to the emission amount expressed in the gradation data corresponding to the light source while the first period is set to the first signal wire to which the anode of the light source is connected, wherein the anode of the light source is connected to the second signal wire in the plurality of light sources, wherein the gradation controller is connected to the plurality of second output pins, and wherein the gradation controller energizes the light source during the second period of the light source connected to the second signal wire in the plurality of light sources with respect to each second output pins connected to the second signal wire used in the designated operation mode.
