PURPOSE:To cut off feed for an exposed electrical equipment at the time of dividing and opening an image forming device by supplying output form DC-DC converter which inputs power-supply voltage through a power source cut-off means to the desired electrical equipment as a control voltage. CONSTITUTION:When the image forming device which can be divided into two, an upper main body and a lower main body, is opened, an interlock switch 3 is interlockingly opened to shut off the feed from an AC-DC converter 6 being a power source unit to a driving system and shut off the feed of the control voltage to the exposed electrical equipment 5 through the DC-DC con verter 8. Meanwhile, the control voltage to the control system of the electrical equipment other than the electrical equipment 5 is not shut off and the power is fed thereto from the converter 6, thereby preventing the loss of data and the occurrence of damage and trouble through the exposed electrical equipment. |
