Light from the infrared diode 10 is reflected by the reflecting object 15 via the light projecting lens 11. 3 and 4 show the painted surface 2
This explains the difference between 0 and the reflection characteristics of the window glass. Light incident on the painted surface is diffusely reflected 19, but light incident on the window glass 18 is vertically reflected without being diffused as shown in FIG.

い。The point of view of the present invention is to determine whether a vehicle is a painted surface or a window glass by the presence or absence of light reception of the reflection type photoelectric switch 3 having both a light emitting function and a light receiving function. As shown in FIG.
When installed at an angle of θ, the painted surface 20 of the vehicle that undergoes diffuse reflection 19 receives light, but reflected light 17 that does not diffuse from the window glass 18 is not received by the reflective photoelectric switch.

いため受光しない。Therefore, it is determined that the part where the vehicle enters and receives the light by diffuse reflection is the painted surface of the vehicle, and the part that does not receive the light is the window glass. FIG. 6 and FIG. 7 are explanatory diagrams of a window discriminating method. FIG. 6 shows changes in the light receiving signals of the transmission type photoelectric switch 2 and the reflection type photoelectric switch 3 due to the passage of the vehicle 8 before the vehicle 8 enters. The light-receiving side of the transmission type photoelectric switch 2 receives light, but the reflection type photoelectric switch 3 does not receive light because there is no reflected light.
【００１８】車両８が進入すると、車両８が光軸を遮断
するため透過型光電スイッチ２は受光しないが、反射型
光電スイッチ３は前記のように車体の塗装部分は受光
し、窓の部分では受光しない。When the vehicle 8 enters, the transmission type photoelectric switch 2 does not receive light because the vehicle 8 cuts off the optical axis. However, the reflection type photoelectric switch 3 receives light on the painted portion of the vehicle body as described above, and on the window portion. No light is received.

窓ガラスであるかを判別する。The height of the window portion that does not receive light is determined by the number of reflection type photoelectric switches 3 that are arranged in advance in the height direction.
Can be detected from the position. FIG. 6 shows a transmission type photoelectric switch 2
And signals from the reflection type photoelectric switch 3 are symbolized and displayed, and it is determined from the combination of these signals whether the vehicle body is a paint portion or a window glass.

あるかの判別は可能である。When the window of the vehicle is open, light may be transmitted. However, if the occupant is shielded and the mesh of the photoelectric switch is reduced, the signal of the transmission photoelectric switch and the signal of the reflection photoelectric switch can be reduced. It is possible to determine whether it is a paint part or a window glass by the distribution of.

(2) Since the pickup unit is at the height of the window of the driver's seat, the driver does not acquire a toll ticket or pay a fee when the driver is in an unstable posture, which leads to safe driving. (3) The cost is reduced because only one collection unit is required.
