PROBLEM TO BE SOLVED: To ensure input to a CPU performed from external equipment through a data bus. SOLUTION: This game machine is provided with a reception side CPU 201 connectable with one or plural external equipment to be a data transmission origin and for receiving data from the external equipment through the data bus, a buffer IC 381 for switching connection/non-connection between a CPU 201 and the external equipment based on changeover command signals from the CPU 201 and a gate signal generation part 216 provided separately from the CPU 201 and interposed between the CPU 201 and the buffer IC 371 for adjusting the timing of the transmission to the buffer 371 of the changeover command signals from the CPU 201. Thus, the collision of the data in the data bus is prevented matched with the characteristics of the various kinds of electronic components.
