1. An electronic device serving as a receiving device, comprising:
- a receiving-end capacitive touch panel that detects contact of a target object or approach thereof, the receiving-end capacitive touch panel including receiving-end sense lines each capable of receiving at least one pulse signal applied to respective transmitting-end drive lines, the receiving-end sense lines being provided in a transmitting-end capacitive touch panel of a transmitting device having contacted or approached the electronic device;
a central processing unit (CPU) that determines a position of the transmitting device in relation to the electronic device by judging which of the receiving-end sense lines has received the at least one pulse signal transmitted from the respective transmitting-end drive lines; and
a receiving-end casing into which the receiving-end capacitive touch panel is incorporated, whereina minimum distance between the receiving-end capacitive touch panel and an outside surface of the receiving-end casing is no longer than a detectable distance within which the receiving-end capacitive touch panel is capable of detecting the contact of the target object with the outside surface or the approach thereof to the outside surface, andthe receiving-end capacitive touch panel receives the at least one pulse signal from the transmitting-end capacitive touch panel of the transmitting device when the transmitting-end touch panel has contacted or approached an end surface of the receiving-end casing.
