PURPOSE:To remarkably save the power consumption by cutting off not only the mechanism part but also all power sources, in case of completing the production of the scheduled number of pieces. CONSTITUTION:A unmanned driving device 20 is provided on a press device 20 and a pulse is generated on each repeating of a motion cycle by the press device 1 on the AC-DC converter 212 thereof. This pulse is added to a counter 220 and the number of manufactured products is displayed 21, the counted value is compared with the production scheduled value in a comparator 222 as well and in case of the coincidence, a coincidence detecting signal is transmitted. The prescribed switch is actuated by this signal and all power sources of crank shaft, compressor 40, motor 11, etc. are cut off. Consequently, the power consumption can be remarkably saved.
