Patent ID: 7778572

Claim:
An opening and closing assembly comprising: (a) a first casing body having a connected portion and a distant portion that is distant from said connected portion; (b) a second casing body having a connected portion and a distant portion that is distant from said connected portion of said second casing body, said second casing body being connected at said connected portion thereof to said connected portion of said first casing body, and being pivotable about said connected portions of said respective first and second casing bodies relative to said first casing body so as to be selectively placed in open and closed positions relative to said first casing body; and (c) a support stand configured to support said second casing body so as to maintain the open position of said second casing body when said second casing body is to be held in the open position, said support stand including (c-1) a proximal end portion that is pivotably connected to said distant portion of one of said first and second casing bodies and (c-2) a distal end portion that is slidably connected to the other of said first and second casing bodies, wherein said other of said first and second casing bodies includes (i) a guide portion configured to guide said distal end portion of said support stand, for permitting said distal end portion of said support stand to be sidable between said connected portion and said distant portion of said other of said first and second casing bodies, and (ii) first and second wall portions opposed to each other and cooperating with each other for gripping said distal end portion of said support stand that is interposed between said first and second wall portions, wherein said distal end portion of said support stand includes a gripped portion at which said distal end portion can be gripped between said first and second wall portions of said other of said first and second casing bodies, and at which said distal end portion can be brought into slidable contact with said first and second wall portions of said other of said first and second casing bodies, and wherein a thickness of said gripped portion, as measured in an opposed direction in which said first and second wall portions are opposed to each other, is increased in a direction away from said distal end portion of said support stand toward said proximal end portion of said support stand.
