PROBLEM TO BE SOLVED: To provide a compact and stable touch sensor circuit. SOLUTION: N sets, from first to nth, of a contact S and an oscillator V for undergoing contact by an object such as the human body and a finger are installed. On the other hand, there is a unitary multiplexer (a) which is a switch for switching over the inputs from the individual oscillators V in order by time division method, and there is also a unitary detector K for detecting contact (touch) by a relevant contact S from the switched-over inputs. The detector K includes a counter (b), a comparator (c), and a latch (d). COPYRIGHT: (C)2007,JPO&INPIT
