Claims

[Scope of Claim for Utility Model Registration] (1) An opening/closing door for an electronic device housing in which the door is arranged so as to cover the opening of the housing housing an electronic circuit unit, and the housing side and the door side are connected by a hinge, The hinge has a notched recess carved in the center of one side of the flat plate, and a rotary shaft support plate that holds the rotary shaft by curling protrusions at both ends of the recess, and a rotary shaft support plate that fits into the notched recess and holds the rotary shaft. It consists of a rotating plate formed on the side end of a flat plate with a semi-circular cylindrical piece projecting in a convex shape, and the rotating support plate is screwed to the housing and the rotating plate is screwed to the door, and the semi-circular cylindrical piece of the rotating plate is screwed. An opening/closing door for an electronic device housing that can be opened and closed by fitting into the notch recess of the above-mentioned rotating shaft support plate and holding the rotating shaft. (2) An opening/closing door for an electronic device casing according to claim 1, wherein a horizontal elongated hole is carved in the rotating shaft support plate.
