Abstract
PURPOSE: To permit maintenance and repairing by separating one of instruments by forming into a loop the control line between the controller to control the making and breaking of power source and plural instruments with independent power source.
CONSTITUTION: When the making and breaking of each instrument 2 to n composing an electronic computer system is commanded by the controller 1, the contact D of the controller 1, besides the usual control line B, and the lowest instrument n connected in series by the control line B are connected together in a loop form by the control line C. Thus, the root to keep the making and breaking state of power source by way of the controller 1 for the instruments 2 to n is doubled, so that, even if one of the instruments 2 to n was separated from the others, the power source making state of the others remains unchanged. Thus, maintenance and repairing can be performed without causing any effect on the other instruments.
