ULTRASONIC WAVE RECEIVER AND POSITION INFORMATION INPUT APPARATUS COMPRISING SAME

摘要

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.

主权项

1. An ultrasonic wave receiver, comprising:
an ultrasonic wave receiving unit including a plurality of ultrasonic wave sensors spaced from each other by a preset distance and configured to receive ultrasonic wave signals generated from a signal generator; an ultrasonic wave receiver housing having the ultrasonic wave receiving unit therein, and having a first magnetic member installed on a lower surface thereof; and a fixing member hinge-coupled to a lower part of the ultrasonic wave receiver housing, and having a second magnetic member installed at a position corresponding to the first magnetic member, wherein the first and second magnetic members are coupled to each other by a magnetic attraction, thereby fixing a writing member on which writing is performed between the ultrasonic wave receiver housing and the fixing member.
