PROBLEM TO BE SOLVED: To facilitate the addition/expansion of information externally output to a parlor computer by a game machine without greatly changing and expanding a communication device, a wiring device and the like existing in a game parlor. SOLUTION: When adding and expanding the information output from a slot machine 1 to a parlor computer 900, an extended information expansion board 300 is interposed in a data bus line CD of an external centralized terminal board 200. A pulse modulation means 101 of the slot machine generates serial data pulses for every information to be added and transmits them to the extended information expansion board using part of existing data bus lines (parallel). A pulse demodulation circuit 301 converts the data pulses into parallel data and outputs them to the parlor computer 900 via extended data lines ED1-ED4. This constitution can facilitate the addition/expansion of the output information to the parlor computer. COPYRIGHT: (C)2008,JPO&INPIT
