Abstract:
Provided is a drive circuit for a two-coil stepper motor, including: a rotor; a stator including first, second, and third stator magnetic-pole portions; a coil A to be magnetically coupled to the first stator magnetic-pole portion and the third stator magnetic-pole portion; a coil B to be magnetically coupled to the second stator magnetic-pole portion and the third stator magnetic-pole portion; a drive pulse generation circuit configured to output a drive pulse; a detection pulse generation circuit configured to output a detection pulse for detecting counter-electromotive currents generated in the coil A and the coil B; and a rotation detection circuit configured to receive a detection signal generated due to the detection pulse as input to determine whether or not the rotor has rotated.

Claim (Index 8):
The drive circuit for a two-coil stepper motor according to  claim 1 ,\n wherein the detection pulse generation circuit is configured to output a detection pulse to be output to one of the first coil and the second coil to which the drive pulse is not output, and wherein the rotation detection circuit has configured to determine whether or not the rotor has rotated with use of the detection signal generated in response to the detection pulse.
