The first signal input circuit 23 and the second signal input circuit 24 are connected to the outer electrode line common line 14 a of the burnout detection sheet 10 via the connection line 30. In order to prevent a negative voltage from being input to the microcomputer 21, an input protection circuit constituted by a diode D whose anode side is connected to the ground is connected to the input side of the CR integration circuit 23a.

  As shown in FIG. 5 (a), the window glass burn-out crime prevention device 1 configured as described above is in a normal state (the window glass WG is not about to be burned out, and the burn-out detection sheet 10 and the burn-out determination are performed. When the microcomputer 21 outputs a pulse signal as shown in the output signal of FIG. 5A via the signal output circuit 22 in a state in which no disconnection is made between the notification unit 20 and the outer electrode line, Since the common line 14a and the inner electrode line common line 15a are connected via the capacitor 16, the first signal input circuit 23 has a rising edge of a pulse signal as indicated by P1 in FIG.

In addition, the signal state of the 2nd step | paragraph of the same figure (a)-(c) has shown the signal state in P1 of the burn-through determination / alerting | reporting unit 20 shown in FIG.

  On the other hand, when the window glass WG is locally heated with a gas burner or a lighter so as to burn the window glass WG, the intermediate transparent film 12 constituting the burn-out detection sheet 10 is melted and intersects in a plane. Since the outer heat-resistant electrode wire 14 and the inner heat-resistant electrode wire 15 are short-circuited, as shown in FIG. 5B, the microcomputer 21 shows the output signal shown in FIG. When the pulse signal is output, the first signal input circuit 23 is input with a pulse signal as indicated by P1 in FIG. 5B, and this pulse signal passes through the CR integration circuit 23a.
