PROBLEM TO BE SOLVED: To improve a utility value of an earphone terminal in a game machine having the earphone terminal as well as a speaker. SOLUTION: This game machine is provided with the speaker 15, the earphone terminal 9 connectable to the earphone 9b, and a sub integration board (a control board) 45 storing speaker sound source data and earphone sound source data; The sub integration board 45 outputs a speaker sound signal generated based on the speaker sound source data to the speaker 15 and outputs an earphone sound signal generated based on the earphone sound source data to the earphone terminal 9. When an earphone 9b is connected to the earphone terminal 9, the sub integration board outputs the speaker sound signal simultaneously with outputting of the earphone sound signal. Such constitution can make the sound from the speaker 15 different from the sound from the earphone 9b to improve the utility value of the earphone terminal 9. COPYRIGHT: (C)2006,JPO&NCIPI
