Abstract: Workbench 6 is for operator performing interior maintenance of casing 2, and laid between casings 2a, 2b when separating casings. A pair of first supporting portions 61 are arranged parallel between casings so as to be able to horizontally support workbench body 60 when casings are in separating state. A pair of second supporting portions 62 are arranged parallel above bottom frame 21a of one casing 2a, and support one ends of first supporting portions 61 when workbench body 60 is in horizontal state. A pair of third supporting portions 63 are arranged parallel above bottom frame 21b with one ends of the third supporting portions 63, to which the other ends of first supporting portions 61 are pivotally fixed, overhanging from bottom frame 21b. Wiring holding section 71 of wiring duct 7 accommodating and protecting wires in casing 2 holds wires under workbench 6 between casings in separating state.

Abstract: A door opening and closing mechanism includes: a door configured to open and close a front side opening of a housing, wherein an electronic device is housed in the housing and is exposed through the front side opening; and an accommodation mechanism configured to accommodate the door in the housing when the door is in open state. The accommodation mechanism includes: an opening and closing action unit configured to cause an opening action and a closing action of the door; and a retracting action unit configured to retract the opening and closing action unit into the housing so as to accommodate the door in the housing, when the door is brought in open state by the opening and closing action unit.

Abstract: When moving casing accommodating electronic equipment for maintenance of electronic equipment, stability of casing is maintained and safety is ensured. Casing separation mechanism 1 separates and connects a pair of casings 2a, 2b. A pair of rail portions 11 are set in bottom frame 21a of one casing 2a with rail portions 11 overhanging from frame 21a. A pair of rail portions 12 extend from one ends of rail portions 11 and retract into rail portions 11 so as to be able to stop during movement of rail portions 12 by rail movement mechanism. A pair of rail portions 13 are set in bottom frame 21b of other casing 2b with rail portions 13 overhanging from frame 21b, and extend from one ends of rail portions 12 and retract into rail portions 12 so as to be able to stop during movement of rail portions 13 by rail movement mechanism.
