Patent ID: 7957675

Claim:
An opening and closing assembly comprising: a first casing having a connected portion and a distant portion that is distant from the connected portion; a second casing having a connected portion and a distant portion that is distant from the connected portion of the second casing, the second casing being connected at the connected portion thereof to the connected portion of the first casing, and being pivotable about the connected portions of the respective first and second casings relative to the first casing so as to be selectively placed in open and closed positions relative to the first casing; and a support stand configured to support the second casing so as to maintain the open position of the second casing when the second casing is to be held in the open position, the support stand including a proximal end portion that is pivotably connected to the distant portion of one of the first and second casings and a distal end portion that is slidably connected to the other of the first and second casings, wherein the other of the first and second casings includes a guide portion configured to guide the distal end portion of the support stand, for permitting the distal end portion of the support stand to be slidable between the connected portion and the distant portion of the other of the first and second casings, and first and second wall portions opposed to each other and cooperating with each other for gripping the distal end portion of the support stand that is interposed between the first and second wall portions, wherein the distal end portion of the support stand includes a gripped portion at which the distal end portion is gripped between the first and second wall portions of the other of the first and second casings, and the gripped portion is brought into slidable contact with the first and second wall portions of the other of the first and second casings, wherein the gripped portion has a cross section having a width and a length, the width of the cross section increases from one end of the cross section to a maximum width, and decreases from the maximum width until the other end of the cross section, the maximum width of the cross section of the gripped portion causes the first and second wall portions of the other of the first and second casings to be spaced apart, wherein the gripped portion is configured to slide between the first and second wall portions in a direction substantially parallel to the length of the cross section of the gripped portion, and wherein the gripped portion includes an elastically deformable member, which contacts the first and second wall portions of the other of the first and second casings, and the gripped portion has a space covered by the elastically deformable member.
