Abstract
PURPOSE:To prevent malaction by constituting a voice detecting circuit provided with a response sound and an environmental sound detecting circuits, in a device which stops generation of an alarm by uttering a sound in response to an alarm sound uttered to an operator. CONSTITUTION:When a signal V is signalled from a cycle signal generator 1 during travelling on an established cycle T through a variable resistor 1a FF2 is set, and an alarm sound is uttered from an alarm circuit 3. When an operator utters properly in response to this alarm sound a voice detecting circuit 4 applies a signal F, FF2 is reset through this signal and an alarm sound generation action is stopped. In this instance, the voice detecting circuit 4 is constituted with the first and the second detecting circuits 4A and 4B which applies voltage in conformity with the volume detected by the circuit 4 and a comparison circuit 4C which makes a comparison between outputs for both circuits 4A and 4B. And the comparison circuit 4C is so constituted that an output of a signal F becomes applicable only when the output of the circuit 4A is larger than that of the circuit 4B.
