や走行安定性の低下を招く要因となる。However, in such a precipitation detection sensor, since the optical system and the circuit board are housed in one case, the whole becomes bulky and large, and it is mounted outside the vehicle. In this case, the precipitation detection sensor is in a state of being largely projected from the vehicle body. For this reason, the appearance of the vehicle is deteriorated, and this becomes a serious problem particularly in the case of an automobile whose purchase desire is greatly influenced by the appearance design. Further, depending on the mounting position, the driver's visibility is significantly impaired, and the protrusion causes air resistance to increase, which causes deterioration of fuel efficiency and deterioration of traveling stability.

A light projecting element 7 such as a light emitting diode, a collimating lens 8 for generating parallel light from the light emitted from the light projecting element 7, and a slit plate for projecting the parallel light from the collimating lens 8 as strip light 10 through a slit hole 9a. 9 and.
On the other hand, the light receiver 3 includes a slit plate 13 in which a slit hole 13a for taking in the band-shaped light 10 from the light projector 2 is formed,
A condenser lens 14 that collects the band-shaped light 10 that has passed through the slit hole 13a, and a light receiving element 1 such as a photodiode that receives the light that has passed through the condenser lens 14.

利点がある。FIG. 6 shows another configuration example of the optical system. In this optical system, the collimator lens 8 is used as means for generating parallel light from the light emitted from the light projecting element 7 in the light projector 2.
A Fresnel lens 16 is used instead of the above, and a Fresnel lens 17 is used instead of the condenser lens 14 as means for condensing the band-shaped light 10 that has passed through the slit hole 13a in the light receiver 3. According to this embodiment, as compared with the embodiment of FIG. 5, the lens portion can be made thinner, and therefore, there is an advantage that the entire sensor can be downsized accordingly.

When the band-shaped light 10 projected from the light projector 2 is received by the light receiver 3, a signal corresponding to the amount of light received is output from the light receiving element 15, but in the space between the light projecting section 1a and the light receiving section 1b. When the raindrop 18 passes through the optical path of the band-shaped light 10 that is formed, that is, the precipitation detection area, the light intensity of the passing area 10a decreases, and the amount of light received by the light receiver 3 decreases accordingly. The change in the output signal from the light receiving element 15 due to the change in the amount of light received detects the presence or absence of precipitation such as rain or snow, and automatically controls the drive of the wiper 51 and the like.

く、非常に高い検知精度が得られる。In this case, since the projection light from the light projecting portion 1a is parallel light, this projection light does not enter the light receiving portion 1b by being reflected on the vehicle body surface or the like, and the light projecting portion 1a and the light receiving portion 1b Even if the optical path between them comes close to the surface of the vehicle body, there is no risk of lowering the detection accuracy. In addition, since the projected light is incident on the light receiving element 15 as the band-shaped light 10 through the corresponding slit hole 13a, the disturbance light and the reflected light hardly enter the light receiving portion 1b, and a very high detection accuracy can be obtained.

制約はない。It should be noted that, when the vehicle travels at an average speed, the raindrops 18 cause the strip-shaped light 10 to pass through the light projecting portion 1a and the light receiving portion 1b.
Slit holes 9a, 1 so that they enter perpendicularly to the strip surface of
It is desirable to set the longitudinal direction of 3a, and usually, the longitudinal direction is set so as to be inclined parallel to the windshield 23. Further, if the slit hole 9a on the side of the light projecting portion 1a is set to be slightly larger than the slit hole 13a on the side of the light receiving portion 1b, the precipitation detection sensor A changes its shape due to the distortion over time, and the band light 10 is projected. Even if the direction is slightly displaced, the band-shaped light 10 causes the slit light 1 on the side of the light receiving portion 1b.
It is possible to maintain the state of passing through the entire area of 3a without exhaustion, and to prevent a decrease in detection accuracy due to a shape change. The opening 12a of the end plate 12b in each waterproof cover 12 has a slit hole 9
There is no limitation on the shape as long as a and 13a are exposed.

構成を省略してもよい。FIG. 7 shows the appearance of a precipitation detection sensor B according to another embodiment. This precipitation detecting sensor B has the same basic configuration as the precipitation detecting sensor A of the first embodiment, but a beam 19 having a circular cross section, which is a parallel light, is projected from the light projecting unit 1a, and this beam is used. 19 is received by the light receiving portion 1b. In this embodiment, the end plate 12b of the waterproof cover 12 is provided with a circular opening 12a which is a light entrance / emission part. In this case, the slit plates 9 and 13 in the first embodiment are used. The corresponding configuration may be omitted.

Since the amount of received light in the receiver decreases, it is possible to detect the presence or absence of precipitation such as rain or snow by the change in the output signal from the light receiver 1b due to the change in the amount of received light. Further, since the beam 19 is parallel light, the projected light is reflected on the vehicle body surface or the like and the light receiving unit 1
Even if the optical path of the beam 19 approaches the surface of the vehicle body, the detection accuracy is not deteriorated.

Further, in addition to the small optical system protruding to the outside, the installation site is not likely to receive air resistance while the automobile 21 is running, and the wiper 51, the washer nozzle 24, and the like are provided, and it is aerodynamically smooth. Since an extra protrusion is not formed in the middle portion of the bonnet 22 to be set on the surface, the increase in air resistance due to the precipitation detection sensor A is very small. Moreover, since it does not obstruct the driver's field of view and is inconspicuous, it has almost no effect on the exterior design of the automobile 21.
