A drowsiness prevention apparatus is provided to be utilized at various users such as a car driver, a machine operator, a night monitor, a student or the like with a compact construction. A drowsiness prevention apparatus includes a slope sensing sensor unit(200), a main body housing(100), a power unit, a relay switch(300), and an alarm unit(400). The slope sensing sensor unit has a bearing unit(210) and a proximity sensor(220). The bearing unit is formed in a shape of a cylindrical capsule where a ball bearing is slidably mounted inside the bearing unit. The proximity sensor outputs an ON signal by sensing the contact of the ball bearing. The main body housing encompasses the slope sensing sensor unit. The power unit supplies power to the slope sensing sensor unit. The relay switch conducts the power to the alarm unit according to the ON signal outputted from the proximity sensor when the power is applied to the power unit. The alarm unit generates an alarm according to the supply of the power. |
