Disclosed are an ultrasonic wave receiver and a location 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 connected to a main body part when location information input is finished. The main body part comprises a large-capacity battery which is 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 connected to the main body part. Accordingly, the present invention can easily be carried by connecting the signal generator and the ultrasonic receiver to the main body part, and additionally can always maintain a charged state by receiving the charging current from the large-capacity battery installed in the main body part. |
