<p><P>PROBLEM TO BE SOLVED: To achieve lowered power consumption and miniaturization by connecting both the ends of a coiled wire to a VDD potential by turning on respective H arms in a bipolar constant voltage drive system reel drive unit. <P>SOLUTION: In a drive and stop control method of step motor for a game machine, the reel stop condition in which the condition for stopping reels by a controller is generated, is generated, thereafter the respective H arms (3, 7) in the respective H bridges (1, 2) are all turned on, when the step motor (5) is stopped by connecting both ends of two-phase coiled wire (10) to a power source potential, after the generation of the reel stop condition, once one face coiled wire (6 or 9) of the two-phase coiled wire (10) is excited, and the respective H arms (3, 7) are turned on after the elapse of a time set as a parameter in the controller (20) in advance. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
