When a page turner is to be accommodated, a holding table is folded, and an air blowing section is rotated and moved toward a side surface of an accommodation case where a page-turning mechanism can be accommodated, whereby the upper surface of the accommodation case and the air blowing port of the air blowing section are substantially flush with each other. Also, an expansion unit is removed from the holding table, and a casing is closed to cover a page-turning main body section constituted by the accommodation case and the air blowing section and the holding table. As a result, the entire page turner is accommodated in a substantially rectangular parallelepiped shape whose vertical and horizontal size is equal to a vertical and horizontal size of a predetermined book. Finally, the page turner is inserted between a pair of side plates constituting leg sections in an image pickup apparatus stand.
