Here, the low voltage charging circuit 174b may include boosting means for boosting the voltage of the DC power supply to a predetermined voltage. That is, when the wave is weak and the voltage of the DC power rectified by the rectifier 172 becomes less than the preset voltage, the voltage may be boosted through the low voltage charging circuit 174b to charge the storage battery 176. As such, the charging controller 174 may perform charging by varying the charging path according to the voltage of the DC power.

The voltage detector 178 may detect the voltage of the DC power rectified by the rectifier 172. The voltage detector 178 may transfer the detected voltage of the DC power supply to the charging controller 174. In addition, when the detected voltage of the DC power supply exceeds a preset threshold voltage, the voltage detector 178 may generate a driving signal for driving the stopper driver 155. Then, the stopper driver 155 rotates the stopper 153 to press the armature 125.
