PROBLEM TO BE SOLVED: To provide a transmission device for, if an opening/closing device of a game machine is opened/closed when a power supply of the game machine is turned off, immediately detecting the opening/closing operation.SOLUTION: A transmission device 10 is mounted on a game machine 50, and includes a power generation part 101 and a radio transmission part 102. When a door 501 of the game machine 50 is opened/closed, the power generation part 101 generates power by kinetic energy generated by the opening/closing operation. When the power generation part 101 generates the power, the radio transmission part 102 wirelessly transmits, using the electricity obtained by the power generation, an opening/closing operation signal representing that the opening/closing operation is performed, to a server device 300 installed outside the game machine 50. |
