Abstract
PURPOSE: To prevent drowsing while driving in such a way that an alarm device is made operated for a moment when the driver does not blink or steer for a specified period during driving.
CONSTITUTION: Photoelectric effective material 5 has its output for the first electric pulse for a moment when the driver has a blink. Photoelectric effective material 7 gives the second electric pulse as output in response to vibration of the vehicle body, at the same time, a switch (e) interrupts both the first and second pulses or leads them to a discharger (f). When the steering wheel is moved, the related part 10 to give the third pulse as output is connected together with the discharger (f) to a switch (i), and in the event of no such pulses within the determined time set by means of a discharger (j), the alarm device 9 actuates forthwith. Since the alarm device actuates for a moment when the driver does not blink or steer for a specified period during driving, drowsing while driving can be prevented.
