Since the light passes through and enters the light receiver 6, the infrared light 19 is detected by the light receiver 17. When the vehicle 2 moves to the normal stop position, the infrared rays 19 are blocked, and at least some of the photoreceptors 17 do not detect the infrared rays 19, so that a detection signal is output from the light receiver 6.

[0006]

In the above-described vehicle position detecting device for a vehicle elevator, as shown in FIG. 3, when the vehicle driver mistakenly drives in the direction of the side wall, the projector 5 or Since the light receiver 6 is installed on the side plate surface in a bare state, the vehicle may come into contact with or collide with the vehicle and the light emitter 5 or the light receiver 6 may be destroyed. In addition to the collision of the vehicle itself,
It was feared that it could be destroyed by intentional mischief because of the psychological effects on the bare. Furthermore, when another vehicle driver uses the vehicle elevator when left in a broken state, the function of the vehicle position detection device itself does not work, causing the vehicle to collide with the rear side plate. There was also a fear of being connected.

The present invention has been made in view of such a situation in the prior art, and even if a vehicle driver accidentally drives in the direction of the side plate, the light emitter or the light receiver is not destroyed. Another object of the present invention is to provide a vehicle position detection device for a vehicle elevator that can prevent intentional mischief.

[0008]

SUMMARY OF THE INVENTION It is an object of the present invention to ascend and descend in a hoistway and enter a car of a vehicle elevator for carrying a vehicle surrounded by a side plate except for an entrance. Further, in a vehicle position detecting device provided with a light emitter and a light receiver for detecting a stop position of the vehicle, a structure in which the light emitter and the light receiver are respectively sandwiched between the side plates, and are installed at a predetermined distance from the surface of the side plate. Is achieved by:

According to the above configuration, when the vehicle driver of the vehicle entering the car accidentally drives in the direction of the side plate, the light emitter and the light receiver are respectively sandwiched between the side plates, and At a predetermined distance from the side plate surface,
Since the light emitter and the light receiver are installed so as to be protected from external force, there is no possibility that the vehicle will contact or collide with the light emitter or the light receiver. Further, since the light emitter or the light receiver is hard to be seen by a vehicle driver, intentional mischief can be prevented.
