Abstract: According to one embodiment, a booklet page turning apparatus includes a guide member which is provided near a vacuum pad to freely project/retreat from a plane corresponding to the suction surface of the vacuum pad, the guide member moving integrally with the vacuum pad and coming into contact with a page of a booklet at the page turning position to regulate rising of the page.

Abstract: In a book document reading device having a page turning capability, a turn belt has a flat portion at the underside thereof and is supported by a turn roller. The turn roller selectively moves the turn belt to a first position where the flat portion of the belt electrostatically attracts the uppermost leaf of a book document, which is spread on a table, in contact with the leaf, or to a second position where the belt is spaced apart from the book document while carrying the uppermost page therewith. When the turn belt is moved from the first position to the second position, a scanning unit is caused to stop moving. This allows the leaf of the document to surely adhere to the turn belt.

Abstract: A sheet turning device for printed sheets supported on a stand which includes a transparent jacket for each sheet, a sheet turning rod secured to each jacket of the stack, the several rods extending side by side, a lever arm fixed to each rod, whereby pulling on a selected lever arm causes rotation of the associated rod and turning of the sheet to the jacket of which the rod is fixed. A set of selector members are disposed side by side and are longitudinally movable in a guide, each selector member is attached to one lever arm. A common pulling member is movable back and forth in a predetermined path under the action of an electromagnet controlled by a foot-actuated switch. The first pulling action causes the first sheet to be turned since only the selector member associated with the first sheet is pulled.

Abstract: A device which will effectively turn a page, for example a page of a booklet of music, enabling a musician to play "hands free", has a book carrier (13) on a frame (11) and a number of page turner subassemblies (16) each with a disc (17) rotatable on an axle (12), each disc (17) having a notch (18) in its periphery, and also having an arm (20) radiating outwardly from the disc (17) and having a clip (57) to engage the page at the swinging end of the arm (20), and a spring (23) which will urge the arm (20) in a pivotal movement of the disc (17) in a page-turning direction, and an escapement mechanism (30) which co-operates with the notches (18) in the discs (17) to inhibit pivotal movement until released by a remote actuated controller (32).
