Abstract
When a mobile unit moves with a motor driven by electric power supplied by a power supply line without a contact when the mobile unit moves where the power supply line exists. The electric power supplied without a contact is also used in charging a electric double layer capacitor. Since the charging current is limited by limiting resistance, the motor can be supplied with sufficient power although the electric double layer capacitor is in a vacant (completely discharged) state.
