Abstract
A frame structure includes a pair of sideboards facing each other, each sideboard having an inner surface provided with a plurality of support grooves for receiving and supporting panel plates, a first joint for fixing one of the pair of sideboards to a base and a second joint for fixing the other of the pair of sideboards to the base and provided with a movement-effecting mechanism. The first and second joints have formed on the facing inner surfaces thereof at substantially the same height steps for contacting side surfaces of the panel plates and supporting the panel plates. At least one of the steps has a surface for contacting at one side surface of one of the panel plates prior to panel plates being received in the plurality of support grooves in order to set a distance between end surfaces of opposed ones of the plurality of support grooves equal to a sum of the width of the panel plates received in and supported by the plurality of support grooves and a predetermined clearance. The at least one surface of the steps projects inward by the predetermined clearance from the end surfaces of the support grooves of one of the pair of sideboards.
