Abstract
Disclosed are an ultrasonic wave receiver and a position information input apparatus comprising same. A signal generator and the ultrasonic wave receiver of the present invention both comprise a rechargeable battery therein whereby same are driven, and are coupled to a main body part when position information input is finished. The main body part comprises a large-capacity battery supplied and charged with a charging current from an external electronic device. Also, the main body part charges the signal generator and the ultrasonic wave receiver by supplying same with a charging current from the large-capacity battery when the signal generator and the ultrasonic wave receiver are coupled to the main body part. Accordingly, the position information input apparatus can easily be carried by coupling the signal generator and the ultrasonic wave receiver to main body part, and can maintain the signal generator and the ultrasonic wave receiver in charged state.
