。[Scope of Claim for Utility Model Registration] 1. In a press brake equipped with a horizontal photoelectric switch above the workpiece placement surface on the operation side, a vertical photoelectric switch that crosses the workpiece placement surface is placed at a predetermined interval between the left and right ends of the operation side. A plurality of upper mold members are provided, and a member for detecting when the upper mold descends and contacts the workpiece, and a member for stopping the lowering of the upper mold when the horizontal photoelectric switch is shielded from light until the detection member detects it; A safety device comprising: a control circuit that stops the lowering of the upper die when a photoelectric switch of the vertical photoelectric switch that is not blocked by the workpiece is blocked from light after being detected by the detection member. 2. The safety device for a press brake according to claim 1, wherein the horizontal photoelectric switch has a light projector and a light receiver disposed facing each other at both left and right ends of the press brake. 3. The press brake safety device according to claim 1 or 2, wherein a plurality of the horizontal photoelectric switches are provided vertically at predetermined intervals. 4. The safety device for a press brake according to claim 1, wherein the vertical photoelectric switch has a light projector and a light receiver arranged opposite to each other above and below the workpiece placement surface.
