-A, PH4-A and light receiving device PH1-B, PH2
-B, PH3-B, and PH4-B are placed at appropriate locations near the vehicle loading/unloading entrance, respectively, to detect the presence of objects that block the irradiation beam of the photoelectric device, in this case people and vehicles. Detects absence, direction of movement, length of vehicle, etc.
Parking equipment may be operated. It is determined whether or not. (PH1 is a photoelectric device consisting of a light projecting device PH1-A and a light receiving device PH1-B, PH2 is a photoelectric device consisting of a light projecting device PH2-A and a light receiving device PH2-B, and PH2 is a photoelectric device consisting of a light projecting device PH2-A and a light receiving device PH2-B. The photoelectric device consisting of the light emitting device PH3-B and the light receiving device PH4-B is referred to as PH3, and the photoelectric device consisting of the light projecting device PH4-A and the light receiving device PH4-B is referred to as PH4. Devices PH2 and PH4 detect the length of the car or the protrusion of the stopping position, and use photoelectric devices.
Distinguishing people and cars using PH1 and PH2 (photoelectric device)
If both PH1 and PH2 irradiation beams are blocked, it is determined that it is a car).

がなされること（立体駐車設備の場合では、実際

人はいないと判断する）があつた。 By the way, due to space constraints, the photoelectric devices PH1 and PH2 are often installed side by side in close proximity, shifted by a small distance in the direction of movement of a moving object, that is, a person or a car, and conventionally Since PH1-A and PH2-A and the light receiving devices PH1-B and PH2-B were installed on the same left and right sides with respect to the moving direction of the object, as shown in Figure 2, the photoelectric devices with poor directivity or the optical axis If the light beams are misaligned, the light beams from adjacent floodlighting devices will be exposed, resulting in false detections that indicate the light reception status even though the original light beams are blocked (in the case of multi-story parking facilities) In this case, it was determined that there was no one inside the tower, even though there were actually people inside the tower.

うな構成にしている。 That is, in the present invention, as shown in FIG. 3, for example, the light projecting device PH1-A of the photoelectric device PH1 and the light receiving device PH2-B of the photoelectric device PH2 are used to detect the movement of an object to either the left or right side with respect to the moving direction of the object. The light receiving device of the photoelectric device PH1 is
Light projection device PH2- of PH1-B and photoelectric device PH2
A is arranged so as to be shifted in the direction of movement of the object on the other side to the left and right with respect to the direction of movement of the object, so that the optical axes of the adjacent photoelectric devices PH1 and PH2 are arranged substantially parallel to each other.

Furthermore, if a plurality of photoelectric devices are used and this detection device is utilized effectively, it is possible to sort out objects of various lengths such as a, b, and c as shown in FIG.
