A plurality of the sensors 60 are provided on the back surface of the toilet seat 62 in the front-rear direction. The pair of electrodes of each sensor are respectively input to the monostable oscillator of the seating position detecting device of FIG. The monostable oscillator, is input frequency (e.g. 50KHz～100KHz) output from the reference oscillator to, Q output of the monostable oscillator Q output and the monostable oscillator is input to the NOR circuit. The output of the NOR circuit is output through the detection circuit, the amplifier and the switching circuit. The constant voltage V _cc is connected to each electrode of the sensor 60 via resistors R ₁ and R ₂ . Further, the voltage obtained by dividing the constant voltage _Vcc by the variable resistor 64 is input to the monostable oscillator.

The operation of this capacitance comparison type seating position detecting device is as follows.

The output of the reference oscillator is input as a reference input to the two monostable oscillators and triggers them. The monostable oscillator has a resistor R₁ And the capacitance C of the sensor 60 ₁ The pulse width of the Q output changes depending on the time constant of. The monostable oscillator has a resistor R₂ And the capacitance C of the sensor 60₂ By the time constant ofQThe pulse width of the output changes. Output of monostable oscillator (Q, Q) are input to the NOR circuit. When the pulse width of each Q output of the monostable oscillator is the same, the output of the NOR circuit becomes zero. This change in pulse width is caused by the capacitance C₁ , C₂ Proportional to the change of. R to ensure that the pulse width of each Q output of the monostable oscillator is the same.₁ , R₂ By changing C and maintaining an equilibrium state,₁ , C₂ Make adjustments so that the effect of surrounding capacitance can be ignored. In this case, as shown in “non-seated” in FIG. 9, the output (Q, Q ) Becomes (0, 1) or (1, 0), and the output of the NOR circuit becomes 0. A human body sits on the toilet seat, and a slight C₁ , C₂ Output of the monostable oscillator (Q,Q) Both become (0, 0), and the output of the NOR circuit becomes 1 at this time. Therefore, when the buttocks of the human body are present on the sensor 60, the NOR circuit outputs a rectangular wave AC signal. This AC output is rectified by a detection circuit to generate a pulsating current close to DC, and further transmitted to a switching circuit through a DC amplifier. It is output to the outside as a digital human body detection signal by the switching circuit. The buttocks position is determined from the array of the sensor 60 that detects the human body and the sensor 60 that does not detect the human body.

The seating position detecting device of FIGS. 7 and 8 is (1) highly sensitive because the output changes depending on the balance of C ₁ and C ₂ ; (2) a wide margin for noise can be taken; (3) Good temperature characteristics;
