To provide a technology capable of shortening the work conveying time between adjacent working devices.

A press conveying device M1 including a first step pressed work discharging hand 8 for taking a work 25 from a first step press 1 (a second step press 4), a second step pressed work charging hand 12 for charging the work 25 to the second step press 4 (a first step press 1), and a conveyor 23 or the like for conveying the work 25 in the direction of the second step press 4 from the first step press 1 is arranged on the upstream and downstream sides in the conveying direction of the work 25 between the first step press 1 and the second step press 4 adjacent to each other. The conveying time of the work 25 from the first step press 1 to the second step press 4 is shortened by performing the charging/discharging operation of the work 25 to/from the first step press 1 and the second step press 4 in a non-synchronous manner with each other.
