A conveyor device capable of conveying a belt-like material from a lower site to an upper site without elongating the belt-like material and without applying unrequired stress thereto. The conveyor device comprises a lower conveyor unit for conveying the belt-like material supplied from material supply means, a central conveyor unit having an induction conveyor which is located adjacent to the front end of the lower conveyor unit and has at least one end movable in a vertical direction, a central conveyor having an inversion conveyor and an expansion conveyor disposed above the lower conveyor unit along a horizontal path, and a unit for expanding or contracting the above expansion conveyor, for inverting the belt-like material received from the above lower conveyor unit and conveying it in an upward direction. Therefore, the belt-like material can be thereby conveyed in an upward direction while the above expansion conveyor is expanded or contracted to increase or reduce the conveyance path of the belt-like material.
