<P>PROBLEM TO BE SOLVED: To further enhance the safety due to an operation stop in an unstable state of a load by a sudden disconnection of a power source and to improve the maintainability while maintaining the safety such as disconnection of the power source by opening and closing of an opening/closing lid formed in a case. <P>SOLUTION: The opening of the opening/closing lid 12A is detected by an interlock switch 36 and while the shutoff of a mechanical load power source supply line 102 is maintained, a load power source supply monitor line 126 is juxtaposed (parallel connected) to the load power source supply line 102 to delay the shutoff of the load power source supply line 102 by using a capacitor 134, and a relay circuit 128 (a coil 128A and a relay switch 128B) and therefore the control extension time to each load 104 by a main controller 108 can be provided and the stoppage during the connection state operation of each load 104 and a mechanism unit can be averted. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
