To provide a conveyor device having a lifting function which can eliminate the need of supplying power from a ground side to a base, which can eliminate the need of communicating between the base and the ground side, and which can accurately lift a load receiving body.

This conveyor device comprises: the load receiving body 2 supported in a liftable and lowerable manner on the base 1; a traveling drive applying a driving force from the outside to the base 1; a converting mechanism 4 interposed between the base 1 and the load receiving body 2 and converting the rotary motion of an input shaft 4E to the vertical linear motion thereof; a lifting drive 6 installed on the side of a feeding path at a predetermined position and engageable with and disengageable from an input shaft 4E, a horizontal reflector attached to the load receiving body 2 with the mirror surface facing downward, a tilted reflector 24 attached to the base positioned just below the horizontal reflector, and a laser distance sensor 22 so installed on the ground that a laser beam L is reciprocated via the tilted reflector 24 and the horizontal reflector when the laser beam L is emitted toward the tilted reflector 24.
