Title: Game machine
Inventor: NASU TAKASHI
IPC: A63F5/04
Filed: 2002-10-11
Abstract: <P>PROBLEM TO BE SOLVED: To provide a game machine wherein rotational swinging during the accelerating period of a drum driving motor is eliminated.  <P>SOLUTION: To eliminate rotational swinging which takes place when a stepping motor is accelerated, exciting time and number of excited phases are controlled to the accelerating period. The exciting time is obtained by holding the motor until swinging ceases. The accelerating period is divided into two stages, and the initial exciting stage is divided into two-phase excitation and one-to-two-phase excitation in the stage leading to constant-speed rotation. Thus, the time required for transition to acceleration can be minimized.  <P>COPYRIGHT: (C)2004,JPO
