The invention concerns an automatic device for turning the pages of a bound document comprising a support ( 11 ) whereon is arranged the document, means ( 14 ) for separating by suction one page from the other pages to be turned and for turning the separated page to bring it on a pile of turned pages. The support ( 11 ) consists of two mobile trays ( 16 ) mutually linked by a rod ( 17 ), each tray consisting of a box ( 26 ) whereof the upper side is provided with small holes ( 27 ) cooperating with the suction intake orifices ( 28 ). The means ( 14 ) for separating the document pages consist of suction means ( 34 ), displaced by the combination of a vertical movement and a horizontal movement, consisting of the perforated recessed element ( 36 ) provided with a diaphragm ( 37 ). Said perforated element ( 36 ) is provided with holes ( 38 ) and the diaphragm ( 37 ) comprises two mobile parts for orienting the direction of the suction flow and modify its flow rate and its speed. Said suction means ( 34 ) also comprise mobile closure means ( 44 ) for longitudinally delimiting the suction surface. The means ( 14 ) for turning a page of the document comprise two mobile transparent plates ( 30 ) arranged in parallel planes. Control means ( 13 ) enable to measure the dimensions of the document and the number of pages turned.
