A vibrating conveyor has a conveying plate (6) which carries objects to be conveyed. The conveying plate (6) is movable back and forth between a first and a second end position by a cam wheel (7) and a pressure spring (8). The cam wheel (7) has on its periphery at least one cam (18) with a cam surface (19) which has a distance to the centre of the cam wheel (7) that increases continuously in the direction opposite to the direction of rotation of the cam wheel (7), and which is terminated abruptly with a substantially radially directed cam surface portion. The pressure spring (8) is arranged to be contracted during the displacement of the conveying plate (6) to the first end position, and then displaces the conveying element to the second end position. The conveying plate (6) has a cam follower (21), which abuts against the periphery of the cam wheel (7) to follow the cam surface of the cam as the cam wheel rotates and move the conveying element (6) to the first end position against the action of the pressure spring (8). The conveying plate (6) is moved so fast from the first end position to the second end position that the objects are not carried along, and so slowly in the opposite direction that the objects are carried along.
