PROBLEM TO BE SOLVED: To provide a belt conveyor device in which a continuous conveying path can be constituted by a single conveyor without combining a separate conveyor even in a layout where the middle of the conveyor is required to be inclined. SOLUTION: An endless conveyor belt 4 is hung between a start end and terminal of conveyor frames 2 bent halfway at a predetermined angle, and a rotatable press roller 7 is vertically movably fitted to a bent frame 3 between the conveyor frames 2. Due to this structure, the first half of the hung conveyor belt 4 is lifted from the conveyor frames 2 depending on a bending angle. However, by pressing this lifted part of the conveyor belt 4 by the press roller 7 fitted to the bending part so as to make the lifted part abuts on the bending shape, the one continuous conveying path with a simple structure can be obtained even in the layout where the middle of the conveyor is required to be inclined. In addition, since the press roller 7 can be vertically moved, this does not prevent passing of conveyed objects. COPYRIGHT: (C)2007,JPO&INPIT
