To raise the whole lid easily when required, even if the lid is comparatively heavy, by providing a vertical movement mechanism which moves a rotary part together with the lid vertically in an opening and closing mechanism of the lid which can open and close the lid centered on the rotary part provided in the vicinity of an end fringe of the lid.
A vertical movement mechanism 3 is embedded in a position which corresponds to the vicinity of one end fringe of a platen cover of a copying machine, only a rotary part connected with an upper end 35a of a vertical movement shaft 35 of the vertical movement mechanism 3 is positioned outside of a main body part in the normal condition, and one end fringe of a lid member is connected with the rotary part in such a manner that it can turn. When a document which is thick such as a book is set on platen glass, rotation force of a motor 32 is transmitted to a drive shaft 33 through an output shaft 32a and a gear 32b, a travelling member 34 screw-fitted in the drive shaft 33 rises together with a bearing plate 37 along a guide member 38, a vertical movement shaft 35 supported on the bearing plate 37 rises and protrudes to the outside of main body part of the copying machine from the upper end 35a, and the platen over rises together with the rotary part.
