ABSTRACT:
A safety apparatus is mounted to the side of a bed of a power press machine on which an operator is positioned for ensuring safety of the operator of the power press machine. The safety apparatus includes a table, for supporting the front end portion of a workpiece, fitted so as to be movable toward and away from the bed at substantially the same height as a fixed mold set to the bed side and on the side of the bed where the operator is positioned. A pair of two-hand operation type switches are fitted to the front side portion of the table with a gap between them, and are operated by both hands of the operator. A deactivating switch is provided for deactivating the pair of two-hand operation type switches when a movable mold set to slide portion side of the power press machine approaches to within predetermined distance of the fixed mold set to the bed side to provide a safety state. Thus, the slide portion is allowed to operate only when the pair of two-hand operation type switches are operated by both hands of the operator and are turned on.
