Abstract
A stepping motor control device is provided with a stopping position determination section and a drive control section. The stopping position determination section determines whether a mover stopping position during the holding state is a stabilized phase or a semistable phase. When it is determined that the mover stopping position is a semistable phase during the holding state by the stopping position determination section, and the control state of the stepping motor transitions from the holding state to the standby state in which the holding of the mover is released due to a trigger signal from a device or the holding state persisting for a fixed time, the drive control section changes the mover stopping position to one of the stabilized phases adjacent to the mover stopping position during the holding state.
