摘要:
A mechanism for swinging a rectangular plate-like panel unit between a first state in which the panel unit is set with its longer sides parallel to a horizontal direction and a second state in which the panel unit is set with its shorter sides parallel to the horizontal direction. The mechanism includes a support unit swingably supporting the panel unit, a first connecting member coupling the panel unit and the support unit, and a second connecting member coupling the panel unit and the support unit. The first connecting member serves as a shaft around which the panel unit is swingable relative to the support unit. The mechanism further includes a first guide groove formed in the support unit to regulate movement of the first connecting member, and a second guide groove formed in the support unit to regulate movement of the second connecting member. The first and second connecting members respectively engage the first and second guide groove and are respectively movable therein when the panel unit is swung between the first and second states.
