<P>PROBLEM TO BE SOLVED: To provide a game machine capable of generating a plurality of vibration patters while suppressing increase in the number of development processes to the utmost. <P>SOLUTION: The game machine includes a push button device 50 installed in a game machine frame 1a and a vibration motor 514 installed in the push button device 50. In the game machine frame 1a, there is provided a vibration motor driving circuit 60 for driving the vibration motor 514 and switching the vibration strength. The vibration motor driving circuit 60 includes: a power source 61 for supplying driving power to the vibration motor 514; a switching circuit 66 for switching the power of the power source 61; and a control signal input part 62 for supplying a first and a second command signals P1, P2 to the switching circuit 66. The vibration motor driving circuit 60 is also provided with a plurality of driving power systems (60a, 60b), wherein the switching circuit 66 switches the systems (60a, 60b) on the basis of the first and the second command signals P1, P2. <P>COPYRIGHT: (C)2013,JPO&INPIT |
