Apparatus for the positioning of a loose leaf or bound pad or book on the work table of an apparatus for printing the individual leaves of the pad or book comprising a holder member which is disposed to extend transversely of the work table and located on or near one end of the work table. The holder member is movable in a plane normal to the upper surface of the work table between a raised inoperative position which allows introduction of a pad or book between the holder and the work table and a lowered operative position in which it can contact and hold the pad or book securely in its position on the work table, a plurality of movable positioning studs for locating the position of the pad or book on the table, are disposed both on a line extending longitudinally of the work table as well as on a line extending transversely of the work table and which are located to one side of the leaf-holder, the positioning studs so co-operating with the leaf-holder that in the operative position of the leaf-holder they are disposed in a downwardly depressed inoperative position, whereas when the leaf-holder is in its inoperative position, they are in their operative position in which they project upwardly from the work table to position a pad or book in the correct position on the work table.
